Purpose: We aimed to systematically review the current literature on the bond strength between custom tray materials and impression materials, including the various parameters affecting the strength. Methods: Four electronic databases were used: Ovid, Web of Science, PubMed, and Scopus. Relevant studies were chosen based on their eligibility, determined through inclusion and exclusion criteria. This review followed the PRISMA strategy. A risk of bias assessment was produced to evaluate the validity of each study. Results: There were 173 initial relevant studies identified, and after the screening process, this was reduced to seven. Two additional studies were also included from hand searching, resulting in total nine studies to be included in the review. Four of the nine evaluated studies concerned additively manufactured (AM) materials, including acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol polyester (PETG), high-impact polystyrene (HIPS), and polylactic acid (PLA). Five studies evaluated an auto-polymerizing resin and one a thermoplastic material. All studies used polyvinyl siloxane impression materials and an adhesive selection following manufacturers’ recommendations. Three studies used scanning electron microscopy (SEM) to analyze their specimens. All studies reported a low risk of bias. Conclusions: Surface roughening was shown to reduce the strength of the bonding interface, whereas combining chemical and mechanical retention was shown to increase the bond strength. Inconsistent results exist in determining if AMed (3D-printed) tray materials are comparable or perform better than the conventional tray materials, highlighting the need for further study. Clinical Significance: The bond strength of the custom tray to the dental impression material is critical as it affects the model produced and therefore the final prosthesis. It is therefore invaluable to use materials with high bond strength for the construction of custom trays. Full article

Background/Objectives: Oral lesions can present with a wide range of clinical appearances, often making diagnosis challenging, particularly for dental students. This study aimed to identify the most common oral lesions treated at a teaching dental clinic and to compare these findings with data from a systematic review of similar clinical settings. The goal was to inform and calibrate a clinical classification system for oral pathology used in teaching environments. Methods: A retrospective analysis was conducted using electronic medical records from a university dental clinic over the past 10 years. Oral and maxillofacial pathology cases were categorized based on clinical and histopathological diagnoses. A systematic review was also performed to provide external context, with searches conducted across four electronic databases. Two independent reviewers carried out the study selection, data extraction, and quality assessment. The review adhered to the PRISMA guidelines. Results: A total of 524 patients were identified with oral lesions. The most frequently encountered clinical diagnostic category was developmental defects, while the most common histopathological diagnosis from biopsied cases was epithelial atypia. The systematic review yielded 1215 records, of which 69 were retrieved for full-text assessment, and 28 studies met the inclusion criteria. Conclusions: The findings highlight the predominance of specific oral and maxillofacial pathoses in teaching clinic settings, underscoring the importance of targeted educational strategies to improve diagnostic confidence among students. There is also a need for more consistent diagnostic grouping in oral pathology to enable better comparison across studies and support clinical and pre-clinical teaching. By integrating these insights, we propose a referenced classification framework that may improve standardization in the clinical teaching of oral lesions and enhance diagnostic calibration and teaching effectiveness in dental education.

Objective: Our aim was to investigate the oral health-related quality of life (OHRQoL) and dental care experiences of adults with Cerebral Palsy (CP). Methods: In 2023, adults with CP and their caregivers from four Australian states completed questionnaires, including the Oral Health Impact Profile-14 (OHIP-14). Non-parametric tests were conducted to analyze associations between demographic and CP-related variables and OHRQoL. Results: A total of 69 respondents participated, including n = 22 adults with CP and n = 47 caregivers of adults with CP. Most adults with CP were diagnosed with a spastic motor type (46/69, 66%), with bilateral spasticity being the most common (30/46, 65%). The mean OHIP-14 score was 10.3 ± 9.3 (mean ± SD). Nearly 70% reported challenges cleaning their teeth, over 25% lacked a dentist, more than 60% found dental exams challenging, and nearly 50% required specialized dental care. In bivariate analysis, OHIP-14 was associated with daily oral care routines (p = 0.012) and “simple dental check-up” (p = 0.017). There was a statistically significant relationship between socio-economic status and scores for the handicap dimension (p = 0.040). Higher OHIP-14 scores were associated with greater levels of impairment regarding gross motor (p = 0.199), manual functioning limitations (p = 0.001), speech (p = 0.123), and communication function scales (p = 0.319). Conclusion: Adults with CP reported challenges participating in and maintaining oral health and accessing dental care, influenced by physical, functional, and socio-economic factors. These findings indicate the need for inclusive care and strategies to support access to services. Full article

Background: Chronic kidney disease (CKD) is a progressive global health burden often diagnosed in late stages due to reliance on invasive and centralized blood and urine tests. Saliva, as a non-invasive diagnostic fluid, has emerged as a promising alternative for assessing renal function. This scoping review aims to evaluate the diagnostic accuracy of salivary biomarkers compared to traditional methods, and to explore the potential of emerging biosensing technologies for CKD detection and monitoring. Methods: A comprehensive literature search was conducted in PubMed/MEDLINE, Scopus, Web of Science, and Cochrane Library up to 1 July 2025, following the PRISMA-ScR guidelines. Studies involving adult CKD patients and healthy controls that assessed the diagnostic performance of salivary biomarkers against validated reference standards (e.g., serum creatinine, eGFR) were included. A total of 29 eligible studies were selected after applying predefined inclusion and exclusion criteria. Results: Salivary creatinine and urea were the most frequently assessed biomarkers and demonstrated strong correlations with serum levels (AUCs up to 1.00; sensitivity and specificity frequently >85%). Several studies reported high diagnostic potential for novel salivary markers such as Trimethylamine N-oxide (TMAO), cystatin C, and amino acids. Technological innovations, including electrochemical biosensors and ATR-FTIR spectroscopy, showed promise for enhancing sensitivity and enabling point-of-care testing. However, heterogeneity in sampling protocols and limited data for early-stage CKD were notable limitations. Conclusions: Salivary diagnostics, supported by biosensor technologies, offer a feasible and non-invasive alternative for CKD screening and monitoring. Standardization, broader clinical validation, and integration into dental workflows are key to clinical implementation. Full article

Objective: The prevalence and severity of obstructive sleep apnea (OSA) increase with age, suggesting that age-related factors are etiological factors for OSA in older adults. In addition to anatomic contractions of the upper respiratory tract, such as those caused by obesity and retrognathia, sleep is impaired in older OSA patients due to aging. Although aging has long been associated with structural changes in the upper airway potential, specific age-related anatomical differences in patients with OSA are not established. This study aimed to examine age-related morphological differences in OSA patients, particularly in older adults. Methods: This study was designed as a retrospective cross-sectional study conducted at the Center for Dental Sleep Medicine, Osaka Dental University, between May 2017 and September 2022. From an initial cohort of 1032 patients, 183 male participants were included after applying strict inclusion and exclusion criteria. Patients were classified into two age groups: middle age (40–60 years) and older age (≥65 years). Polysomnographic parameters; body mass index (BMI); airway space (AS) obtained from cephalometric radiographs; length of the soft palate (PNS-P); SNB angle, as an indicator of mandibular position; and the position of the hyoid bone (MP-H) were compared between the groups. Statistical analysis included Levene’s test for homogeneity of variances, independent sample t-tests for group comparisons, and multiple regression analyses to identify independent predictors of AHI. This study was conducted with the approval of the Ethics Committee of Osaka Dental University (No. 111047). Results: Older patients showed significantly lower REM sleep percentage (13.5 ± 1.31% vs. 16.4 ± 0.59%, p = 0.047), significantly lower BMI (23.6 ± 0.45 kg/m² vs. 24.6 ± 0.29 kg/m², p = 0.049), and significantly larger AS (15.8 ± 0.52 mm vs. 12.0 ± 0.27 mm, p = 0.000) compared to middle-aged patients. Furthermore, in the middle-aged group, BMI (β = 0.40, 95% CI: 1.46 to 3.41, p < 0.001), SNB (β = −0.18, 95% CI: −1.75 to −0.09, p = 0.030), and MP-H (β = 0.19, 95% CI: 0.10 to 1.01, p = 0.018) were significant independent predictors of AHI. In the older group, no parameters were significant predictors of AHI. Conclusions: We found that older adult patients had a larger airway diameter and lower REM sleep percentage and BMI than middle-aged patients. Furthermore, regarding factors associated with AHI, which is an indicator of sleep apnea severity, in the middle-aged group, anatomical factors such as BMI, SNA, and MPH contributed significantly, but in the older adult group, anatomical factors were not relevant. The results suggested that anatomical factors alone may not fully explain the pathogenesis of OSA in older patients, highlighting the need for further studies focusing on other age-related factors.

Background: Bovine bone-derived xenografts are widely used in regenerative dental procedures due to their osteoconductive properties and volumetric stability. However, their long-term behavior and biological integration remain a subject of debate. This systematic review aims to critically assess the histological and clinical outcomes associated with bovine xenografts over extended follow-up periods. Methods: An electronic search was performed in PubMed, Scopus, and Web of Science, including studies published in the English language from 2005 to 2025 for a total of 217 records, which were initially identified from PubMed, Scopus, and Wos. Results: After duplicate removal, following title/abstract screening and full-text evaluation, 11 studies met the inclusion criteria. These studies reported on the use of bovine-derived xenografts in clinical contexts, assessing parameters such as graft integration, histological remodeling, complication incidence (e.g., chronic inflammation or foreign body reactions), and implant success rates over time. Conclusions: The current evidence suggests that bovine-derived xenografts, particularly Bio-Oss^®, are associated with favorable long-term outcomes in bone regenerative procedures, demonstrating satisfactory graft integration and implant survival rates. However, variations in study design, follow-up duration, and outcome measures warrant further high-quality, long-term randomized clinical trials to confirm these findings and guide clinical decision-making.

Background/Objectives: This review aimed to evaluate whether patients undergoing dental extractions while taking antidepressants experience increased intra-operative or post-operative bleeding compared to patients not taking these medications. Methods: A comprehensive literature search was conducted across PubMed, EMBASE, Web of Science, Scopus, and ClinicalTrials.gov for randomized controlled trials (RCTs) published before 17 August 2025. Studies were included if they compared bleeding outcomes between antidepressant users and non-users undergoing dental extraction procedures. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered with the International Prospective Register of Systematic Reviews (PROSPERO, CRD42025645035). Results: Of 689 studies screened, no RCTs met the eligibility criteria. Only one retrospective study, which did not match the inclusion criteria, identified a 1% incidence of bleeding complications in users of selective serotonin reuptake inhibitors (SSRIs) undergoing invasive dental procedures. However, it lacked a control group and standardized methodology, so this study was included in the discussion section. Conclusions: The lack of high-quality evidence, especially studies examining dynamic coagulation parameters like bleeding time and prothrombin time before and after antidepressant use, highlights a significant gap in the research. These findings emphasize the urgent need for well-designed clinical trials to determine the potential effect of antidepressants on bleeding risk. Full article

Background/Objectives: This scoping review aims to map existing AI applications in dental education, in student learning, assessment, and diagnostic training, identifying key limitations and challenges. Methods: Following the Arksey and O’Malley framework and PRISMA-ScR guidelines, six databases were searched in March 2025 using combinations of the following search words: “dental education,” “artificial intelligence,” “machine learning,” and “student assessment”. Inclusion was limited to English-language empirical studies focused on dental student education. Of 547 identified studies, 17 met the inclusion criteria. They were categorized into four domains: (1) Preclinical Training, (2) AI in Clinical, Diagnostic Training, and Radiographic Interpretation, (3) AI as an Assessment Tool and Feedback System, and (4) AI in Content Generation for Dental Education. Results: AI has positively influenced various domains, enhancing procedural accuracy, diagnostic confidence, assessment efficiency, and content delivery. However, it struggles to assess nuanced competencies like dexterity and clinical judgment. The challenges faced include disparate definitions of AI, ethical and privacy concerns, model variability, and a deficiency of dental leadership in AI development. At present, most tools are engineered by computer scientists and may not align effectively with the priorities of dental education. Conclusions: AI holds significant potential to enhance dental education outcomes. However, to guarantee its relevance and reliability, it requires standard frameworks, ethical oversight, and clinician-led development. Future research should concentrate on implementing real-time AI-driven feedback systems during preclinical training and advocate for more precise definitions to support consistent AI application and evaluation in dental education.

This systematic review aimed to evaluate the association between Helicobacter pylori in the oral cavity as an extragastric reservoir and oral diseases in patients with or without gastritis. Following the PRISMA guidelines, a comprehensive search was conducted on the PubMed, Scopus, Cochrane Central, and Embase databases (2010–2025) using MeSH terms and keywords related to H. pylori, the oral cavity, and oral diseases. Inclusion criteria included observational studies, clinical trials, and case–control studies. Data extraction and quality assessment were performed using the Newcastle–Ottawa Scale (NOS). Of the 298 records initially identified, 22 studies met the inclusion criteria. The presence of H. pylori in the oral cavity (plaque, saliva) was variably associated with gastritis, periodontitis, dental caries, and halitosis. Detection rates varied widely (0–100%), influenced by methodological differences (PCR, culture, antigen tests). Some studies reported an improvement in oral health after eradication therapy, while others found no significant association. The oral cavity may serve as a reservoir for H. pylori, with implications for oral and systemic health. Standardized diagnostic methods and integrated treatment approaches (combining gastric eradication and oral hygiene) are needed to clarify their role and optimize clinical outcomes. Further research is warranted to establish causal relationships and therapeutic strategies. Full article

Background: Dentistry is undergoing a digital transformation driven by emerging technologies such as Artificial Intelligence (AI), Internet of Things (IoT), Digital Twins (DTs), and Large Language Models (LLMs). These advancements offer new paradigms in clinical diagnostics, patient monitoring, treatment planning, and medical education. However, integrating these technologies also raises critical questions around security, privacy, ethics, and trust. Objective: This review aims to provide a structured synthesis of the recent literature exploring AI, IoT, DTs, and LLMs in dentistry, with a specific focus on their application domains and the associated ethical, privacy, and security concerns. Methods: A comprehensive literature search was conducted across PubMed, IEEE Xplore, and SpringerLink using a custom Boolean query string targeting publications from 2020 to 2025. Articles were screened based on defined inclusion and exclusion criteria. In total, 146 peer-reviewed articles and 18 technology platforms were selected. Each article was critically evaluated and categorized by technology domain, application type, evaluation metrics, and ethical considerations. Results: AI-based diagnostic systems and LLM-driven patient support tools were the most prominent technologies, primarily applied in image analysis, decision-making, and health communication. While numerous studies reported high performance, significant methodological gaps exist in evaluation design, sample size, and real-world validation. Ethical and privacy concerns were mentioned frequently, but were substantively addressed in only a few works. Notably, IoT and Digital Twin implementations remained largely conceptual or in pilot stages, highlighting a technology gap in dental deployment. Conclusions: The review identifies significant potential for converged intelligent dental systems but also reveals gaps in integration, security, ethical frameworks, and clinical validation. Future work must prioritize cross-disciplinary development, transparency, and regulatory alignment to realize responsible and patient-centered digital transformation in dentistry. Full article

Background: The purpose of alveolar ridge preservation (ARP) is to minimise the physiological alveolar ridge reduction occurring after dental extraction, which can prevent the need for future alveolar ridge augmentation. Biologic materials (biologics) promote tissue regeneration based on their effect on wound healing at a cellular level. By integrating biologics into ARP biomaterials, there is a potential to enhance the regeneration of both hard and soft tissues with greater efficacy. Aim: This narrative review aims to evaluate the clinical efficacy of the addition of biologics to existing ARP materials on the physiological changes following ARP of an extraction site. Methods: A search of the PubMed electronic database was conducted, and relevant articles were examined. Sixty-three articles met the inclusion and exclusion criteria and were included in this review. Results and Conclusions: A review of the existing literature found that the combination of biologics with ARP materials resulted in similar dimensional changes when compared to using ARP materials alone. Existing research has identified an enhancement in bone density, increased wound healing capacity of soft and hard tissue, and a reduction in post-operative pain. Whilst the addition of biologics to ARP materials has shown an increase in bone density, its effectiveness in improving implant outcomes and reducing the need for future alveolar ridge augmentation is unclear. Recognising the limitations within the existing literature, along with the risk of bias and heterogeneity, renders it unwise to make definite conclusions about the benefits of integrating biologics with ARP materials. This narrative review found possible benefits in the use of biologics in ARP to optimise patient-related and treatment outcomes, indicating the need for additional research. Full article

Odontophobia, defined as the intense and persistent fear of dentists or dental care, is a widely underestimated, yet clinically significant, barrier to oral health. It affects individuals across all age groups, from children to the elderly, and is particularly prevalent among those with intellectual or developmental disabilities. Odontophobia is a multifactorial condition influenced by psychological, sensory, cognitive, and sociocultural factors. Left unaddressed, it contributes to poor oral health outcomes, avoidant behavior, and broader health disparities. This perspective paper explores the clinical manifestations and principles of management of odontophobia across populations and different age groups, highlighting the limitations of pharmacological sedation, especially when used in isolation. Instead, evidence supports the use of cognitive behavioral strategies, desensitization protocols, sensory-adaptive environments, and communication-based approaches, such as the “tell-show-do” method. Innovative technologies, including virtual reality, offer additional promise. This paper also addresses critical gaps in the research, the paucity of tailored interventions for vulnerable groups, and both ethical and legal complexities surrounding consent, autonomy, and equitable access. Ultimately, managing odontophobia requires a shift toward “person-centered” and “trauma-informed” dental care, supported by interdisciplinary collaboration, inclusive infrastructure, and policy-level commitment to reduce fear-based disparities in oral health.

Background: Dental professionals face high levels of occupational stress, which intensified during the COVID-19 pandemic, contributing to increased burnout, diminished well-being, and signs of accelerated biological aging. This systematic review explores the role of physical activity as a protective factor for mental and physical health, with a focus on promoting resilience and long-term occupational sustainability in a post-pandemic volatile, uncertain, complex, and ambiguous (VUCA) environment. Methods: A systematic review was conducted in accordance with PRISMA 2020 guidelines. Studies published between 2000 and 2024 were identified through PubMed, Scopus, and the Cochrane Library using MeSH terms related to dentistry, physical activity, stress management, and occupational health. Of 850 records screened, 28 studies were included: 24 cross-sectional, 2 systematic reviews, 1 retrospective, and 1 case–control study. Inclusion and quality appraisal followed standardized criteria. Results: The included studies consistently showed that physical activity was associated with reduced burnout, improved psychological well-being, enhanced postural function, and potential markers of slowed biological aging in dental professionals. Several studies reported moderate-to-strong associations, with effect sizes ranging from small improvements in perceived stress scores to substantial reductions in MSD prevalence. Interventions combining exercise with ergonomic education, stress management, and institutional support demonstrated the stronger and more consistent benefits for professional sustainability. Conclusions: Physical activity, when integrated into comprehensive workplace wellness frameworks, significantly enhances the mental and physical resilience of dental professionals. Embedding movement, ergonomics, and psychosocial support into practice environments offers a promising strategy for safeguarding long-term workforce sustainability and improving public health outcomes.

Introduction: Dental caries remains a public health concern, and early detection prevents its progression and complications. Panoramic radiographs are essential diagnostic tools, yet the interpretation of panoramic X-rays varies among practitioners. Artificial intelligence (AI) presents a promising approach to enhance diagnostic accuracy in detecting dental caries. This scoping review examines the current literature on the use of AI programs to analyze panoramic radiographs for the diagnosis of dental caries. Methods: This scoping review searched PubMed, Scopus, Web of Science, and Dentistry and Oral Sciences Source, adhering to PRISMA guidelines. The review included peer-reviewed, original research published in English that investigated the use of AI to diagnose dental caries. Data were extracted on the AI model characteristics, advantages, disadvantages, and diagnostic performance. Results: Seven studies met the inclusion criteria. The Deep Learning Model achieved the highest performance (specificity 0.9487, accuracy 0.9789, F1 score 0.9245), followed by Diagnocat and Tooth Type Enhanced Transformer. Models such as CranioCatch and CariSeg showed moderate performance, while the Dental Caries Detection Network demonstrated the lowest. Benefits included improved diagnostic support and workflow efficiency, while limitations involved dataset biases, interpretability challenges, and computational demands. Conclusions: Applying AI technologies to panoramic X-rays demonstrates the potential for enhancing caries diagnosis, with some models achieving near-expert performance. However, future research must address the generalizability, transparency, and integration of AI models into clinical practice. Future research should focus on diverse training datasets, explainable AI development, clinical validation, and incorporating AI training into dental education and training. Full article

Background/Objectives: The functionalization of various forms of graphene, such as graphene nanoplatelets, graphene oxide, and reduced graphene oxide, in biomaterials is a promising strategy in dentistry, particularly regarding their antimicrobial potential. However, conclusive studies on the toxicity and biocompatibility of graphene-based materials remain limited, and standardized guidelines for their production, handling, and dental applications are still lacking. This scoping review aims to map the available studies on various types of graphene, synthesize evidence on their antimicrobial effectiveness, and describe the main biological responses when functionalized in dental biomaterials. Methods: An electronic search was conducted in the Clarivate, PubMed, and Scopus databases using the descriptors as follows: ‘graphene’ AND ‘antimicrobial effect’ AND ‘bactericidal effect’ AND (‘graphene oxide’ OR ‘dental biofilm’ OR ‘antibacterial properties’ OR ‘dental materials’). Article screening and eligibility assessment were performed based on predefined inclusion and exclusion criteria, following the PRISMA-ScR guidelines. Results: The search identified 793 articles. After removing duplicates, applying the eligibility criteria, and performing a full-text analysis of 64 articles, 21 studies were included in the review. Graphene oxide, particularly at low concentrations, was the most commonly studied graphene variant, demonstrating significant antimicrobial efficacy against S. mutans, S. faecalis, E. coli, P. aeruginosa, and C. albicans. Both mechanical and chemical mechanisms have been linked to the biological responses of graphene-doped biomaterials. The biocompatibility and cytotoxicity of these compounds remain controversial, with some studies reporting favorable outcomes, while others raise significant concerns. Conclusions: Graphene shows great promise as an antimicrobial agent in dental biomaterials. Despite encouraging results, more in vitro and in vivo studies are needed to better understand its biocompatibility and cytotoxicity in dental applications. Additionally, standardized production protocols, clearly defined clinical applications in dentistry, and regulatory guidelines from the World Health Organization concerning handling procedures and occupational risks remain necessary.
