Background: The US has state variation in edentulism, commonly known as total tooth loss, in older adults. This paper identifies key social determinants of health (SDOH) associated with state differences in older adult edentulism that can be addressed with partnerships between dental providers and policymakers. Methods: Data was collected from three publicly available data sets, including County Health Rankings, provided by the University of Wisconsin Population Health Institute, the U.S. Centers for Disease Control and Prevention (CDC), and the Centers for Medicare and Medicaid Services (CMS). Results come from multiple regression analysis of panel data for all states and the District of Columbia for even years of 2012–2020. Results: A variety of SDOH, population health behaviors, and demographics are associated with older adult edentulism, with the largest effects for education and smoking. We have other variables of interest, and overall, our model explains over 80 percent of the variation. Conclusion: Policymaking in states should emphasize both education and smoking cessation programs for individuals. Future research may also consider the relationship between state-regulated dental insurance and dental practice location. States may also consider policies to encourage better dental professional training and incentives to address smoking cessation for patients. Full article

Background/Objectives: Dental caries remains one of the most prevalent chronic diseases affecting children worldwide and continues to pose a substantial challenge to healthcare systems. Although the clinical consequences of paediatric dental caries are well documented, the associated economic burden has not been comprehensively synthesised. This systematic review aimed to evaluate and summarise the available evidence regarding the costs associated with dental caries in children and adolescents under 18 years of age. Methods: A systematic review was conducted in accordance with PRISMA 2020 guidelines and registered in PROSPERO (CRD420251138979). MEDLINE via PubMed, Scopus, and Dentistry & Oral Sciences Source (EBSCOhost) were searched for studies published between January 2012 and July 2025. The MEDLINE and Scopus searches were conducted on 22 July 2025, and an additional search of Dentistry & Oral Sciences Source (EBSCOhost) was conducted on 19 August 2026. Eligible studies included peer-reviewed cost-of-illness studies, economic evaluations, cost analyses, cross-sectional studies, retrospective studies, and randomised controlled trials reporting economic outcomes related to the prevention or management of dental caries in individuals under 18 years of age. Methodological quality was assessed using the Drummond 10-item checklist. Data were extracted on study characteristics, population demographics, cost components, study perspective, and key findings. Reported costs were categorised as direct, indirect, and intangible costs where applicable. Due to substantial methodological heterogeneity among studies, a narrative synthesis was performed. Results: Seventeen studies met the inclusion criteria. Most studies focused on direct medical costs associated with restorative treatment, hospital-based dental care, and emergency services. Direct costs were consistently substantial across different healthcare settings, particularly for cases requiring advanced treatment or general anaesthesia. Preventive interventions were generally reported to be more cost-effective than curative approaches. Indirect costs, including caregiver productivity losses, were infrequently assessed, while no study comprehensively evaluated intangible costs. Considerable variation in study design, costing perspective, and reporting methodology limited direct comparison across studies. Conclusions: Dental caries in individuals under 18 years of age imposes a considerable economic burden, driven primarily by direct treatment costs. Preventive oral health strategies appear to provide greater economic value than treatment-focused approaches. The limited assessment of indirect and intangible costs suggests that the overall societal burden of paediatric dental caries is likely underestimated. Future research should adopt standardised and comprehensive costing methodologies to better support policy development and resource allocation in paediatric oral healthcare. Full article

Background/Objectives: Oral diseases are common, largely preventable and closely associated with social determinants, noncommunicable diseases and quality of life. Greece has historically had a high dentist-to-population ratio; however, oral health care remains highly dependent on private provision and out-of-pocket payment. This structured evidence synthesis and health-system mapping aims to summarize the current situation of oral health care in Greece, focusing on access, financing, workforce capacity, epidemiology, prevention, and quality measurement. Methods: A structured evidence synthesis and health-system mapping were conducted using publicly available and verifiable sources, including World Health Organization documents, OECD/European Observatory country health profiles, Eurostat data, official Greek government information, and peer-reviewed studies identified through PubMed, Google Scholar, publisher records, and reference-list searching. The final synthesis included 29 sources: 15 peer-reviewed articles and 14 official or institutional documents/data sources. A formal systematic review, with or without meta-analysis, was not methodologically feasible because the research question was not based on a single intervention, exposure, comparator, or outcome, and because key evidence on oral health-system organization, financing, and governance is contained in heterogeneous policy documents, administrative sources, official reports, and country profiles that are not consistently indexed in bibliographic databases. Evidence was organized across predefined health-system domains: governance, service delivery, financing, workforce, epidemiology, equity, information systems, and quality measurement. Results: Greece combines high dentist density with limited public dental coverage and major financial barriers. Current EOPYY rules list age-specific preventive and treatment benefits, and Dentist Pass provided a preventive dental-care voucher for children; however, no ring-fenced national dental-treatment allocation or nationwide uptake estimate was identified. Most routine adult dental care remains privately financed. Recent Eurostat data indicate that Greece has the highest reported unmet dental care needs in the European Union. Comparative WHO country-profile indicators suggest that Greece’s high dentist density does not, by itself, correspond to lower unmet dental care needs or stronger publicly reported coverage of routine and preventive oral health care. Epidemiological studies show persistent caries, periodontal disease and tooth loss, particularly among children, older adults and socioeconomically disadvantaged groups. Major system-level gaps include limited financial protection, weak integration with primary care, insufficient standardized referral pathways and limited routine measurement of oral health quality and outcomes. Conclusions: The findings suggest that strengthening oral health care in Greece would require a shift from fragmented, curative and privately financed care toward prevention-oriented, publicly accountable and measurable services integrated with universal health coverage and national quality-of-care reforms.

Background/Objectives: Dental caries remains one of the most prevalent chronic diseases in childhood, influenced by a combination of hygiene, dietary, and access-related behaviours that are largely shaped by parental involvement. This study aimed to evaluate oral hygiene habits, dietary risk factors, access to dental services, awareness of caries prevention, and the impact of oral health on the child, in relation to parent-reported dental caries in Romanian children and adolescents. Methods: A cross-sectional study was conducted using a structured online questionnaire completed by parents or legal guardians of 508 children and adolescents aged under 18 years. Associations between categorical variables and reported caries were assessed using chi-square tests and Cramér’s V. Ordinal variables were compared using the Mann–Whitney U test. A multivariable logistic regression identified independent predictors of reported caries, with robustness examined through sensitivity analyses. Results: Parent-reported caries was present in 61.2% of children. The strongest associations with caries were the absence of parental supervision during brushing (Cramér’s V = 0.364), the age at which children began brushing unsupervised (V = 0.354), and the reason for the last dental visit (V = 0.426). In the multivariable model, older age, absence of brushing supervision, sweets before bedtime, less frequent dental visits, and rural residence were independent predictors (all p < 0.05; Nagelkerke R² = 0.361). All six assessed dimensions of oral-health impact on the child were significantly associated with caries, with physical discomfort showing the largest effect (V = 0.349). Conclusions: Parent-reported caries risk in this population clustered around a small number of modifiable behaviours rather than any single dominant factor, while reported caries was associated with a substantial burden on children’s daily functioning. These findings point to sustained parental supervision and routine, non-symptomatic dental care as priority targets for future prevention efforts, although intervention studies are needed to confirm their effectiveness.

Early childhood dental caries (ECC) remains one of the most prevalent and preventable chronic diseases affecting young children globally, yet behavioral and contextual determinants of its onset during the first 1000 days of life remain poorly understood and infrequently modeled in Latin American populations. This study presents a novel application of the PRECEDE diagnostic framework to conceptualize Early Childhood Dental Caries during the first 1000 days (1000ECDC) as a behaviorally rooted, socio-ecologically conditioned health problem. Drawing on a formative longitudinal pilot study (n = 10 mother–infant dyads, Caracas, Venezuela) and a complementary narrative literature review, we develop the first PRECEDE-based conceptual model linking maternal prenatal and postnatal behaviors to dental caries risk in a Latin American context. The model identifies dietary and feeding behaviors, oral health care practices, and healthcare service utilization as primary behavioral risk factors, modulated by predisposing factors (low oral health knowledge, limited self-efficacy, cultural norms), enabling factors (socioeconomic constraints, fragmented health systems), and reinforcing factors (social norms, family influence). Exploratory pilot findings indicated that more than 60% of children had advanced dental caries lesions at 24-month follow-up, consistent with regional estimates and underscoring the urgency of early intervention. This model provides practitioners and policymakers with a structured, evidence-informed diagnostic tool to guide the design of early-life oral health promotion programs, with particular relevance for low-resource Latin American settings. Future validation through expert consensus and prospective studies is warranted. Full article

Background/Objectives: Dental trauma is recognized as a global public health problem due to its prevalence and psychosocial consequences. This study aimed to verify the prevalence of traumatic dental injuries in practitioners of combat sports and whether they were associated with sociodemographic and sports variables in a capital city in southeastern Brazil. Methods: This cross-sectional observational study included 284 athletes over 18 years of age from 17 academies that offered combat sports. Data collection was performed by a single examiner through individual interviews and a questionnaire addressing sociodemographic profile, access to oral health services, sport modality, experience with dental trauma during combat sports, mouthguard use, and guidance on dental injuries. Descriptive analyses, frequency tables, the Chi-square test (p < 0.05), and Odds Ratio were used. Results: Most participants were male (n = 203; 71.48%), aged up to 25 years (n = 75; 26.41%). The most practiced sports were Jiu-Jitsu (n = 79; 27.82%) and Kickboxing (n = 77; 27.11%). Among participants who suffered dental trauma (n = 19; 6.69%), single episodes predominated (n = 9; 47.37%), enamel fractures were most frequent (n = 7; 36.84%), and anterior teeth were the most affected (n = 9; 47.36%). Most were not using a mouthguard at the time of trauma (n = 15; 78.95%), although they considered mouthguard use important (n = 229; 80.63%), and most had not received guidance on dental trauma (n = 237; 83.45%). Age group was significantly associated with dental trauma (p = 0.016; OR = 3.33; 95% CI: 1.167–9.524). Conclusions: The prevalence of dental trauma among fighters was low. Mouthguard adherence was inconsistent, post-trauma management was inadequate, and most respondents had never received guidance on dental trauma. Public health policies should strengthen awareness and prevention of dental injuries in sports. Full article

Background/Objectives: Children with special healthcare needs (CSHCN) face significant barriers to conventional dental care and frequently require general anaesthesia (GA). Data characterising the clinical and therapeutic profile of this population in the Spanish public health system remain scarce. This study aimed to describe the systemic conditions, oral pathology, and dental procedures performed in CSHCN attending a tertiary-care paediatric oral and maxillofacial surgery service, and to characterise the subgroup of patients requiring treatment under GA relative to the wider clinic population. Methods: A retrospective, descriptive, observational study was conducted at the Hospital Universitario y Politécnico La Fe (Valencia, Spain) from November 2022 to February 2026. Data were extracted from electronic health records for 160 outpatient clinic patients aged 0–14 years (70.6% male), of whom 42—a subgroup, not an independent sample—subsequently underwent dental treatment under GA (76.2% male). Sex, age, and autism spectrum disorder (ASD) status were compared between the GA subgroup and a non-overlapping outpatient-only comparator (n = 118) using Fisher’s exact test and Welch’s t-test. Results: ASD was the most prevalent systemic condition in both the outpatient clinic (25.0%) and the GA subgroup (42.9%); a statistically significant association with ASD status was observed against the non-overlapping outpatient-only comparator (18.6% ASD; p = 0.003), while sex (p = 0.432) and age (p = 1.00) did not differ. Dental caries was the most common finding at outpatient assessment (61.0%), followed by root remnants (32.1%). Among GA patients, tooth extraction was performed in 78.6%, composite restoration in 71.4%, and professional dental cleaning in 50.0%. The mean number of procedure types per GA patient was 2.5 ± 1.0 (range 1–5); 81.0% received two or more procedure types in a single session. Conclusions: CSHCN attending this service present advanced oral disease, and those referred for GA had a significantly higher prevalence of ASD than the remaining clinic population, requiring complex, multi-procedure interventions in a single session. The wide geographic pattern of referrals suggests that further evaluation of the distribution of hospital dental services within the public health network may be warranted, and caregiver-targeted preventive programmes may represent a promising strategy to reduce the oral disease burden in this population.

Background and Objective: Glucagon-like peptide-1 (GLP-1) receptor agonist therapy has intensified the policy debate over whether obesity pharmacotherapy increases short-term healthcare expenditures or reduces downstream medical costs (i.e., non-drug, acute-care expenditures). This study estimated same-year associations between GLP-1 use and medical spending among adults with observed obesity. Methods: Analyses used Medical Expenditure Panel Survey (MEPS) person-year files compiled from 2018 to 2022, with body mass index (BMI)-defined analyses restricted to 2019 and 2021. The primary analytic sample included 7144 person-years, of which 275 represented sustained GLP-1 users. Overlap-weighted Poisson pseudo-maximum likelihood models, utilization regressions, two-part decompositions, and a layered diagnostic framework were applied to assess spending patterns and same-year cost implications. Robustness was evaluated through sensitivity analyses across all-obesity, severe-obesity, and diabetes-excluded subsamples, as well as exploratory molecule-specific specifications. Results: Findings showed no evidence of same-year cost savings, but rather a distinct shift in spending composition. In fully adjusted primary models, GLP-1 use was associated with reduced non-drug medical spending (beta = −0.2494; marginal effect = −$2586 per person-year) and lower acute-care spending (beta = −0.5856; marginal effect = −$2019), while total medical spending was higher (beta = 0.3182; marginal effect = +$6483). Point E values of 1.89 (non-drug) and 2.99 (acute-care) indicated moderate-to-strong resilience to unmeasured confounding. Negative control models using dental spending and visits showed significant positive associations. Since this residual confounding operates in the direction opposite to the negative acute-care association, the headline compositional pattern is unlikely to be an artifact of upward health-seeking bias. Utilization models indicated fewer inpatient discharges (IRR = 0.686) and inpatient nights (IRR = 0.524). Two-part models further suggested that the reduction in acute-care spending was concentrated on the intensive margin among individuals with positive expenditures. Conclusions: The use of GLP-1 is not associated with overall short-term cost savings. This usage is related to a shift in the composition of observed medical spending during the same year. This change is leading to a decline in hospital admissions and acute care costs, in parallel with the rise in pharmaceutical spending. Non-drug and acute-care costs were lower among regular users. However, total spending was at a higher level, consistent with a trend in the budget records from that period in which drug costs were the dominant factor. These associations are consistent with a potential reallocation of healthcare resources from inpatient acute care toward pharmacy and ambulatory services, with corresponding planning implications for payers and possible workforce reallocation of nursing capacity from acute to outpatient settings, contingent on replication in post-2022 data.

Background/Objectives: Romania’s National Health Insurance House (CNAS) reimbursement basket is the principal public financial-protection mechanism, yet whether it reflects the therapeutic services patients actually seek has not been tested against private-market offerings. This study compared the public basket with the private dental service portfolio, using the latter as an indirect, supply-side signal of expressed need rather than a direct measure of demand. Methods: In this cross-sectional study (November 2024–February 2025), the publicly listed portfolios of 420 private dental practices in Bucharest (n = 256), Cluj-Napoca (n = 104), and Iași (n = 60) were analyzed, stratified by size (0–3 vs. >3 employees). Practices were identified from CAEN 8623 records on listafirme.ro; portfolios were extracted from official websites displaying prices. Services were classified as functional or aesthetic by two independent raters (Cohen’s κ = 0.91), with disagreements resolved by consensus. Results: Across all municipalities and strata, approximately 53–68% of private services fell outside the CNAS basket. Critically, about 95–96% of private services were functional rather than aesthetic (4–5%), indicating that the gap reflects functional treatments patients seek and providers offer yet that remain unfunded—not elective demand. No statistically significant geographic differences emerged. Geographic location was not associated with portfolio breadth, whereas in multivariable models larger practices (>3 employees) independently offered approximately 33% more services. Conclusions: Because the analysis reflects advertised portfolio breadth rather than utilization, and a documented Romanian orientation toward reactive over preventive care, these hypothesis-generating findings make private supply a pragmatic, supply-side reference point for evidence-based revision of the CNAS basket, pointing to two directions directly supported by the data—aligning coverage with observed demand and administrative simplification of contracting. To our knowledge, this is the first benchmarking of the CNAS basket against private supply, relevant to other predominantly private European dental systems. Full article

Background and Objectives: Individuals with heroin-related opioid use disorder are at high risk of poor oral health and impaired oral health-related quality of life (OHRQoL). However, data on the determinants of OHRQoL in this population remain limited. This study aimed to assess oral health status and OHRQoL and to identify key predictors of OHRQoL among hospitalized patients with heroin-related opioid use disorder. Materials and Methods: A cross-sectional study was conducted among 97 hospitalized patients with heroin-related opioid use disorder. Data were collected through structured interviews and clinical oral examinations, including the Decayed, Missing, and Filled Teeth (DMFT) index and the Simplified Oral Hygiene Index (OHI-S). OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14). Spearman correlation and multiple linear regression analyses were performed to examine associations and identify predictors of OHRQoL. Results: Participants had poor oral health, with high DMFT (19.1 ± 6.1) and OHI-S (2.0 ± 1.2) scores. OHRQoL was markedly impaired, with a mean OHIP-14 score of 29.6 ± 7.0, particularly in the psychological and social domains. OHIP-14 scores were strongly correlated with DMFT (r = 0.754, p < 0.001) and OHI-S (r = 0.552, p < 0.001). Longer duration of heroin use was associated with higher DMFT scores, poorer oral hygiene, and greater OHRQoL impairment. Multiple linear regression analysis identified unstable housing/homelessness (β = 0.166, p = 0.012), DMFT (β = 0.624, p < 0.001), and OHI-S (β = 0.272, p = 0.007) as significant predictors of poorer OHRQoL. Conclusions: Individuals with heroin-related opioid use disorder experienced substantial oral health burden and impaired OHRQoL, strongly associated with caries experience, poor oral hygiene, and housing instability. These findings highlight the need to integrate prevention-oriented dental care into addiction treatment services and to address the broader social determinants of oral health. Full article

Background/Objectives: Access to dental care is a multilevel challenge shaped by healthcare systems, individual characteristics, and broader social determinants. This study aimed to identify parent-reported barriers to dental care among a sample of children in Saudi Arabia using Levesque’s Conceptual Framework for Access to Healthcare. Methods: A cross-sectional survey was conducted between March and April 2023 among parents of children aged 1–18 years. The 44-item survey assessed sociodemographic, oral health, and dental care utilization, organized using Levesque’s access dimensions. Difficulty accessing needed dental care within the past 12 months served as the main outcome. The chi-square test was used to examine bivariate associations between potential barriers and difficulty accessing needed dental care. Multivariable logistic regression was used to identify factors independently associated with difficulty accessing needed dental care after adjustment for the other variables. Results: This study included 351 parents. The mean age of children was 10.7 ± 4.7 years, and 45.9% were male. One-third of parents reported difficulty accessing needed dental care for their children. The adjusted regression model identified fair/poor oral health (aOR = 13.39, 95% CI: 6.19–28.97), general health condition (aOR = 2.31, 95% CI: 1.11–4.82), and the absence of a nearby dental clinic (aOR = 2.08, 95% CI: 1.11–3.90) as factors independently associated with difficulty accessing dental care. Conclusions: Applying Levesque’s framework highlighted the multidimensional nature of barriers to accessing dental care for the study population. These findings provide preliminary evidence on parent-reported access barriers and may inform larger, representative studies and future policies to improve equitable pediatric oral healthcare in alignment with Saudi Vision 2030.

Objective: Varicella zoster virus (VZV), a member of the Herpesviridae family, is known as the causative agent of chickenpox (varicella). Following primary infection, VZV can remain latent for life and may reactivate over time to cause herpes zoster (shingles). Advanced age, immunodeficiency, and certain chronic illnesses are major risk factors for the development of herpes zoster. To prevent herpes zoster, a live zoster vaccine was licensed in 2006, followed by a recombinant zoster vaccine with higher efficacy in 2018. In Türkiye, the recombinant zoster vaccine was licensed in 2024. Raising awareness among healthcare workers is important both for their own health and the safety of vulnerable patients. This study aimed to evaluate healthcare workers’ knowledge and awareness of herpes zoster infection and zoster vaccines across the country, as well as to determine the prevalence of prior herpes zoster infection among them. Methods: After obtaining ethical approval, a nationwide multicenter survey was conducted. A questionnaire was distributed to healthcare workers via an online link. Participation was entirely voluntary. The survey collected demographic information (age, sex, profession, years of experience) and included questions on knowledge of herpes zoster, history of zoster infection, symptoms and severity (if applicable), awareness of the zoster vaccine, and vaccination attitudes. Results: A total of 5180 healthcare workers participated, of whom 3505 were female. The participants ranged in age from 18 to 79 years (mean age: 34.24 ± 11.52). Regarding professions: 47.9% were physicians, 21.3% were nurses or midwives, 0.8% were dentists or dental technicians, and 30% were from other healthcare professions. Among participants, 54.4% had ≤10 years of professional experience, 20% had comorbidities, and 10.5% were using immunosuppressive medications. It was found that 9.6% had previously had herpes zoster, 8.8% had no knowledge of the disease, 39.6% were aware of the vaccine, and 20.1% were unwilling to pay for vaccination. Multivariate binary logistic regression analysis revealed that being a physician significantly increased the likelihood of having correct knowledge by 1.961 times compared to other professions (p < 0.001, CI: 1.608–2.392). Similarly, those who had heard of herpes zoster were 3.191 times more likely to answer correctly than those who had not (p = 0.011, CI: 1.650–6.172). Male gender was significantly associated with a lower likelihood of having accurate knowledge compared to females (p = 0.001, OR = 0.720, CI: 0.594–0.874). Conclusions: This study revealed that healthcare workers’ knowledge and awareness regarding herpes zoster and its vaccines are generally insufficient. The recent licensing of the vaccine in Türkiye may explain this, but it is critical for healthcare professionals to be more informed about risk groups and vaccination indications in order to enhance the effectiveness of preventive healthcare services. Given the potential for serious complications of herpes zoster in elderly and immunocompromised individuals, the importance of vaccination should be emphasized more strongly to healthcare workers. Furthermore, the finding that 20.1% of those aware of the vaccine were deterred by its cost highlights the need to improve vaccine accessibility. Economic barriers preventing healthcare workers from being vaccinated emphasize the importance of making the vaccine widely available through public support to protect both healthcare workers and patient safety.

Background: Individuals with sensory impairments often encounter barriers to oral health information, preventive care, and dental services. Despite a growing body of research, oral health among individuals with hearing and visual impairments has not been comprehensively evaluated across the full spectrum of oral health outcomes. This systematic review aimed to evaluate oral health outcomes and dental treatment needs in individuals with hearing and visual impairments. Methods: A literature search was performed in Ovid MEDLINE, Ovid Embase, and Web of Science from database inception to 8 January 2026, in collaboration with a medical information specialist, and in accordance with the PRISMA 2020 guidelines. Observational studies reporting oral hygiene, periodontal status, dental caries, dental needs, and other relevant oral health outcomes in individuals with hearing and visual impairments were included. Given the substantial clinical and methodological heterogeneity across the included studies, findings were synthesized using a narrative approach. Results: A total of 5650 records were identified, of which 84 studies were included. Oral health problems were frequently reported among individuals with sensory impairments. Dental caries was the most common finding. Poor oral hygiene, gingival inflammation, periodontal problems, and unmet treatment needs were also often described. Additional findings included traumatic dental injuries, malocclusion, salivary and microbiological alterations, functional oral limitations, and reduced oral health-related quality of life. Conclusions: Individuals with sensory impairments are likely to experience poorer oral health and considerable unmet dental needs. These findings highlight the need for improved preventive strategies, effective communication approaches, and more inclusive dental care. Full article

Background/Objectives: Dental caries remains a major public health problem in childhood and disproportionately affects socioeconomically disadvantaged populations. Although toothbrushing and oral hygiene are commonly promoted as key preventive behaviours, their protective effect may be limited by structural factors such as access to dental care, fluoride exposure, and preventive services. This study aimed to compare dental caries experience, oral hygiene status, toothbrushing frequency, and sugar consumption among disadvantaged children from the Peruvian Amazon and Valencia, Spain, and to explore whether differences in hygiene behaviours were reflected in caries outcomes. Methods: An exploratory cross-sectional school-based study was conducted among 291 children aged 5–12 years attending three purposively selected schools serving socioeconomically disadvantaged communities: one rural school in the Peruvian Amazon (n = 162) and two urban schools in Valencia, Spain (n = 129). Dental caries experience was assessed using a combined global caries score derived from the dmft and DMFT (CAOD/cod) indices according to dentition type, and oral hygiene status was evaluated using the Simplified Oral Hygiene Index (OHI-S). Toothbrushing frequency and sugar consumption were collected through structured questionnaires. Group comparisons, Spearman correlation analyses, and exploratory multiple linear regression models were performed. Results: Mean global caries scores did not differ significantly between Peruvian and Spanish children (3.71 ± 2.86 vs. 4.07 ± 3.44; p = 0.596). However, severe caries experience (score ≥ 8) was more frequent among Valencian children (21.7% vs. 10.5%; p = 0.014). Peruvian children showed significantly better oral hygiene status (OHI-S-derived score: 1.25 ± 0.79 vs. 1.49 ± 0.84; p = 0.014) and higher toothbrushing frequency (p < 0.001). Frequent sugar consumption was similarly high in both groups. Within each population, poorer oral hygiene and lower toothbrushing frequency were associated with higher caries experience in bivariate analyses, although the exploratory multivariable models showed a more limited pattern of association. Conclusions: Among the participating schools, children from the Peruvian Amazon showed better oral hygiene indicators and more frequent toothbrushing than Spanish children, while no statistically significant difference in caries experience was detected. Because structural variables such as fluoride exposure, dental attendance, and access to restorative care were not directly measured, explanations involving healthcare infrastructure should be considered as candidate hypotheses to be tested in future, adequately powered and adjusted studies, rather than as confirmed mechanisms. Findings should not be generalised beyond the participating schools. Full article

Pediatric dental diseases, notably dental caries, malocclusion, and dental trauma, remain a significant public health challenge in China, exerting considerable impact on children’s oral and general health. Despite growing societal demand for pediatric dental care, China faces a critical shortage and uneven geographic distribution of pediatric dentists, alongside persistent urban–rural disparities in access to oral health services. These challenges underscore the urgent need for educational reforms, workforce policy adjustments, and assessment of the strengths and limitations of recent training initiatives to enhance pediatric dental service delivery. This narrative review aims to: (I) describe the current structure of pediatric dental education in China and recent reforms, notably the integration of degree education with standardized residency training; (II) summarize the epidemiological burden of dental diseases among Chinese children, together with contributing social and geographic factors; (III) outline national policy initiatives targeting children’s oral health and existing gaps in implementation; and (IV) discuss innovations in dental education, including student-centered pedagogies and humanities integration. This review provides a comprehensive overview of pediatric dentistry in China and offers strategic recommendations to strengthen workforce training, expand service access, and reduce the burden of pediatric oral diseases.
