Background/Objectives: This retrospective observational study evaluated associations among dentition type, age, systemic conditions, and oral pathology in pediatric patients. Methods: A six-month retrospective analysis was conducted in a specialized pediatric hospital. Patients (n = 155; 0–18 years) were grouped as clinically healthy with oro-maxillofacial diseases or with systemic diseases. Data included dental/periodontal status, anomalies, gingival bleeding index, IOTN score and oral mucosal conditions. Statistical tests (chi-square, ANOVA, and correlations) were applied. Results: Chronic gingivitis was most frequently associated with primary dentition. Caries and root debris were more frequent in ages 4–6, while acute gingivitis appeared in younger children. Orthodontic treatment need increased with age, especially in mixed dentition. Periodontal diseases were most often linked to digestive pathologies. Conclusions: Oral health in children showed associations with age, dentition type, and systemic conditions. Findings highlight associations rather than causation, underscoring the importance of prevention, early monitoring, and age-appropriate interdisciplinary management. Full article

Background: Cardiovascular diseases (CVDs) are linked with poor oral health outcomes, yet data on oral health status, behaviors, and awareness among CVD patients in Odisha remain scarce. This study aimed to assess the self-reported oral health status, behaviors, and knowledge among patients with CVD and associated risk factors. Methods: A cross-sectional survey was conducted among 391 patients aged 40–80 years attending dental and cardiology OPDs at a tertiary care center in Bhubaneswar. Participants were grouped into control, at-risk, and established CVD categories. A 24-item questionnaire and panoramic radiographic examination were used to assess oral health. Data were analyzed using the chi-squared test and Kappa statistics. Results: Patients with established CVD reported significantly higher prevalence of oral health problems, poor oral hygiene behaviors, and lower awareness compared to controls. Clinical findings revealed higher rates of periodontal bone loss, caries, and periapical radiolucency in the CVD group. Agreement between radiographic examiners was high. Conclusions: There is a substantial burden of oral disease and poor oral health awareness among patients with CVD in Odisha. These findings emphasize the need for integrated oral health education and care protocols in cardiovascular patient management. Full article

Background. Orthodontic extrusion (OE), or forced eruption, is a conservative technique used to recover teeth affected by coronal fractures, traumatic intrusions, or severe caries. It involves applying light, continuous forces to induce vertical tooth movement, promoting tissue remodeling through periodontal ligament stimulation. Materials and Methods. This narrative review included studies investigating OE as a therapeutic approach for the management of deep or subgingival carious lesions, traumatic dental injuries (such as intrusion or fracture), or for alveolar ridge augmentation in implant site development. OE is typically performed using fixed appliances such as the straight-wire system or, in selected cases, clear aligners. Forces between 30 and 100 g per tooth are applied, depending on the clinical situation. In some protocols, OE is combined with fiberotomy to minimize gingival and bone migration. Results. Studies show that OE leads to significant vertical movement and increases in buccal bone height and interproximal septa. It enhances bone volume in targeted sites, making it valuable in implant site development. Compared to surgical crown lengthening, OE better preserves periodontal tissues and improves esthetics. Conclusions. In this narrative review is analized how OE is effective for managing traumatic intrusions and compromised periodontal sites, particularly when paired with early endodontic treatment. It reduces the risks of ankylosis and root resorption while avoiding invasive procedures like grafting. Although clear aligners may limit axial tooth movement, OE remains a minimally invasive, cost-effective alternative in both restorative and implant dentistry. Full article

Background: Traditional visual-tactile methods, radiographic interpretation including CBCT imaging, clinical judgement and supplementary aids such as fluorescence-based devices are pivotal components of the restorative diagnostic process in detecting dental caries and defective or failed restorations. However, when evaluating the restorability of a tooth compromised by extensive and deep caries, whether associated with a failed restoration or not, the conventional approach may not provide sufficient diagnostic information to establish a definitive restorative diagnosis without first removing failing restoration, caries or both. Objective: This manuscript presents caries clearance management (CCM) as a novel comprehensive clinical diagnostic restorative procedure designed to assist dentists in making a final restorative diagnosis regarding the restorability of a tooth compromised by extensive caries, fractured tooth cusp(s) or a failed large direct/indirect restoration without caries or a combination of all of them. Practical implications: CCM involves removing the failed direct/indirect restorations and selective removal of carious tissue while preserving the greatest amount of sound tooth structure as possible. Following this clinical diagnostic procedure and an assessment of dental pulp and periodontium, the clinician proceeds through a decision-making process to determine the final restorative diagnosis. This allows the dentist to advise the patient on a suitable complex restorative treatment plan. Conclusions: The manuscript introduces caries clearance management (CCM) as a structured clinical diagnostic procedure, to assist dentists to determine the restorability of compromised teeth by extensive caries, fractured teeth or failed large direct or indirect restorations.

X-linked hypophosphatemic rickets (XLH) is a rare genetic disorder with a frequency of 1:20,000, caused by mutations in the PHEX gene, resulting in impaired phosphate metabolism and bone mineralization. There is an association between hypophosphatemia and dental issues, though this link is not definitively established. This study aims to evaluate the dental status, including oral hygiene, caries prevalence, and malocclusions, as well as parental awareness of dental complications, in children with XLH in Bulgaria, particularly those receiving or about to begin burosumab treatment, and to compare their oral health status with that of healthy children. Eleven children with XLH (seven girls, four boys, aged 2.5–17 years), nine receiving burosumab, were assessed and compared with eleven age- and gender-matched healthy children (seven girls, four boys, aged 2.5–17 years) without XLH or systemic conditions affecting dental health. Parental awareness of dental implications was assessed via a questionnaire, revealing no awareness of potential complications. Oral hygiene, measured using the Oral Hygiene Index-Simplified (OHI-s), was poor in 66.67% of children, with an average of 6.45 ± 5.80 carious lesions per child, and was highest in the 11–16 age group. Malocclusions were observed in 63.64% of children, and spontaneous endodontic infections occurred in 18.18%. Compared with healthy children, patients with XLH had significantly worse oral hygiene (p = 0.013) and a higher caries prevalence (p = 0.001). Children with XLH exhibit poor oral hygiene, a high caries burden, and frequent malocclusions, compounded by a lack of parental awareness of dental risks. These findings underscore the need for targeted dental interventions and education in XLH management, including the integration of routine dental assessments and structured parental education programs into existing clinical protocols to improve oral health outcomes.

Background: Dental caries is a prevalent dental problem affecting primary and permanent teeth. Early demineralization of enamel lesions can be reversed through remineralization. Many studies have focused on caries prevention and disease progression arrest using silver diamine fluoride (SDF). No in vitro studies have compared the remineralization effects of different 38% SDF solutions on artificially demineralized enamel lesions. This study aimed to compare the remineralization potential of three commercial 38% silver diamine fluoride formulations on artificial enamel lesions in primary teeth using a pH cycling model. The hypothesis was as follows: different commercial SDF formulations would exhibit varying remineralization effects, as measured by surface microhardness, due to potential differences in their compositions. Materials and Methods: In this study, 75 primary molars were randomized into five groups (N = 15): I: baseline, II: SDF Riva Star Aqua^® 38%, III: Riva Star^® 38%, IV: SDF Advantage Arrest^® 38%, and V: control. Artificial caries were created by submerging teeth in 10 mL of demineralization solution (pH 4.5) for three days in a light-resistant container, ensuring distinct visual changes in the enamel as per the International Caries Detection and Assessment System (ICDAS level 2). After pH cycling, all samples underwent a standardized Vickers microhardness test (VMHT) with a 50 g load for 15 s. Data were analyzed using one-way ANOVA and Tukey’s post hoc test, with a significance level set at p ≤ 0.05. Results: The one-way ANOVA test indicated a significant difference in microhardness among the groups (SDF Riva Star Aqua, SDF Riva Star, and SDF Advantage Arrest), with an F-value of 167.73 and p < 0.001. The post hoc Scheffé test showed that SDF Riva Star Aqua and SDF Riva Star were not significantly different (p = 0.388). However, SDF Advantage Arrest had a significantly higher mean microhardness compared to both groups (p < 0.001). Overall, these results show that SDF Advantage Arrest leads to greater microhardness than SDF Riva Star Aqua or SDF Riva Star. Conclusions: SDF Advantage Arrest showed superior performance among the SDF-treated groups, significantly increasing microhardness compared to SDF Riva Star Aqua and SDF Riva Star. This suggests that SDF Advantage Arrest offers enhanced remineralization and structural strengthening, making it the most effective option for managing demineralized primary teeth. Future research should investigate the long-term performance and mechanisms of these treatments to optimize clinical protocols for preserving primary tooth integrity. Full article

Background/Objectives: Caries risk assessment is essential for the management of dental caries. There are different assessment methods with the most commonly used being CAMBRA, the Cariogram, and Caries Risk Semaphore (CRS). The aim of this study was to determine the diagnostic agreement between the three different caries risk assessment methods mentioned above. Methods: This study was conducted in the Dental Clinic of the University of Valencia by Preventive and Community Dentistry II students on patients examined during clinical practices (n = 672). Patients were evaluated to determine their caries risk using the three methods named above. A descriptive analysis of the sample was performed, and diagnostic agreement was assessed using the Kappa coefficient. Results: According to CRS, 321 patients (48%) showed high risk, 96 patients (14%) moderate risk, and 255 (38%) low risk. The highest diagnostic agreement was found between CRS and CAMBRA, with an unweighted Kappa of 0.36. Regarding risk severity assessments, the highest Kappa was also observed between CRS and CAMBRA, with a Kappa of 0.46 for low risk, 0.14 for moderate risk, and 0.40 for high risk. Conclusions: There is an important heterogeneity in the obtained results. This highlights the need to further study different caries risk assessment methods and determine their predictive capacity to choose the one that yields the best outcome. Full article

Background: Early caries management is essential to enable reversal of white spot lesions without the further need for operative interventions, especially in primary dentition. Silver-based compounds can be quite effective in arresting caries lesions; however, a major drawback is teeth staining. This study aimed to evaluate the remineralization potential and aesthetic effects of novel, green-synthesized nano-silver fluoride (NSF) on artificial white spot lesions in primary teeth in comparison to 38% silver diamine fluoride (SDF) and silver diamine fluoride/potassium iodide (SDF/KI). Materials and Methods: NSF was synthesized using green tea extract. Sixty primary teeth specimens with artificial enamel lesions were randomly divided into five groups depending on the applied material: 38% SDF, 38% SDF/KI, single and double application of NSF, and control group. Treatments were followed by pH cycling. Surface microhardness and photographic analysis were conducted to assess remineralization and staining. Statistical analysis was conducted using non-parametric tests including Kruskal–Wallis and Mann–Whitney U tests with Bonferroni correction. Results: The greatest increase in microhardness was observed in the group receiving double NSF application. Its remineralizing potential was comparable to that of 38% SDF/KI, with no statistically significant difference (p = 1.000). Importantly, NSF-treated samples exhibited no teeth discoloration, unlike the black staining observed in SDF and SDF/KI groups. Conclusions: Green-synthesized NSF is a promising alternative to conventional SDF and SDF/KI, offering remineralization benefits without compromising aesthetics. The eco-friendly formulation and non-staining properties support its potential for clinical use in pediatric dentistry. Full article

Gene therapy has emerged as a promising therapeutic approach across various oral diseases. This review examines current applications and future prospects of gene therapy in dentistry, focusing on five key areas: oral cancer, cancer-related pain, xerostomia (dry mouth), dental caries, and periodontal disease. Recent advances in viral and non-viral vectors have enabled more efficient gene delivery systems, with particular success in cancer pain management through µ-opioid receptor gene transfer and xerostomia treatment using aquaporin-1 gene therapy. For periodontal applications, gene therapy strategies include both immunomodulation and tissue regeneration approaches using growth factors like platelet-derived growth factor and bone morphogenetic proteins. While significant progress has been made, particularly in treating radiation-induced xerostomia and oral cancer pain, challenges remain in vector optimization and delivery methods. Clinical trials, predominantly in Phase I, indicate both the potential and current limitations of gene therapy in oral healthcare. This review synthesizes current evidence and outlines future directions for gene therapy applications in oral medicine and dentistry. Full article

Background: AI has been adopted in dentistry for diagnosis, decision making, and therapy prognosis prediction. This systematic review aimed to identify AI models in dentistry, assess their performance, identify their shortcomings, and discuss their potential for adoption and integration in dental practice in the future. Methodology: The sources of the papers were the following electronic databases: PubMed, Scopus, and Cochrane Library. A total of 20 out of 947 needed further studies, and this was encompassed in the present meta-analysis. It identified diagnostic accuracy, predictive performance, and potential biases. Results: AI models demonstrated an overall diagnostic accuracy of 82%, primarily leveraging artificial neural networks (ANNs) and convolutional neural networks (CNNs). These models have significantly improved the diagnostic precision for dental caries compared with traditional methods. Moreover, they have shown potential in detecting and managing conditions such as bone loss, malignant lesions, vertical root fractures, apical lesions, salivary gland disorders, and maxillofacial cysts, as well as in performing orthodontic assessments. However, the integration of AI systems into dentistry poses challenges, including potential data biases, cost implications, technical requirements, and ethical concerns such as patient data security and informed consent. AI models may also underperform when faced with limited or skewed datasets, thus underscoring the importance of robust training and validation procedures. Conclusions: AI has the potential to revolutionize dentistry by significantly improving diagnostic accuracy and treatment planning. However, before integrating this tool into clinical practice, a critical assessment of its advantages, disadvantages, and utility or ethical issues must be established. Future studies should aim to eradicate existing barriers and enhance the model’s ease of understanding and challenges regarding expense and data protection, to ensure the effective utilization of AI in dental healthcare.

This review highlights key findings, identifies research gaps, and underscores the therapeutic potential of LTP in managing complex oral biofilm-related infections. Full article

Oral caries is one of the most common oral diseases worldwide, affecting about 2.4 billion people. This phenomenon always starts with enamel demineralization, eventually progressing to tooth cavitation and loss when not properly treated. Nowadays, the standard diagnostic techniques to detect demineralization strongly depend on the operator’s expertise and are characterized by fairly low sensitivity and specificity, and/or involve ionizing radiation. This study investigates the feasibility of a non-invasive, effective, rapid, and radiation-free approach employing impedance spectroscopy for early caries detection. Two binary classifiers were developed for automated assessment and validated using a dataset obtained by in vitro demineralization of human teeth. A computationally efficient single-neuron classifier, utilizing a single impedance phase measurement at 15 Hz, achieved 88% accuracy, offering a lightweight, low-power solution suitable for microcontroller implementation and rapid measurements. A Multi-Layer Perceptron (MLP) classifier, utilizing equivalent circuit element values, yielded a similar accuracy of 86%. A prototype of a diagnostic portable tool was developed and characterized, demonstrating reliable impedance phase measurement (uncertainty < 2°). The performance of these classifiers meets or exceeds the existing AI-based methodologies for caries detection relying on radiographic data. This work introduces a novel application of AI to tooth impedance spectra, addressing a significant research gap in non-invasive diagnostics and laying the foundation for a novel, accessible, and accurate tool for early caries management.

Background/Objectives: Deep caries lesions represent an actual concern in preserving tooth vitality and preventing irreversible pulpitis. As presently the non-selective approach is considered an overtreatment, the concept of selective caries removal is highly recommended. The goal of this narrative review is to focus on current trends in carious dentine excavation and adjunctive therapies. Methods: A keyword-based selection of scientific publications issued in the last six years, i.e., 2019–2024, was conducted with the search engine of PubMed (MEDLINE) and ScienceDirect databases, using the following keywords: deep carious lesion; caries removal; indirect pulp capping; adjunctive antimicrobial therapy; adjunctive anti-enzymatic therapy; biomimetic restorative dentistry. Discussions: In deep caries management, the current trends of carious dentine excavation recommend preferentially partial caries removal technique as less risky to pulp exposure and more conservative compared to the stepwise technique (SW). Presently, advanced additional procedures such as antimicrobial photodynamic therapy and an anti-enzymatic approach are also considered for caries arrest. Conclusions: Selective caries removal and adjunctive photodynamic antimicrobial therapy are procedures of choice in preserving pulp vitality. Anti-enzymatic therapies impede decoupling with time of adhesive restorations from the smear layer. Biomimetic restorative dentistry and smart materials introduce the principles of artificial intelligence in the therapeutic approach of deep caries. Full article

Background/Objectives: Oral health is a complex concept involving physical, psychological, emotional, and social components. A key factor in maintaining oral tissue integrity is redox balance, which is disrupted by oxidative stress (OS) through an imbalance between reactive oxygen species (ROS) and antioxidant defenses. This study examines the contribution of endogenous and exogenous sources to OS and explores the therapeutic potential of medicinal plants from the Asteraceae and Lamiaceae families in restoring redox homeostasis and improving oral health. Methods: A literature review was conducted, analyzing the role of OS in oral diseases and the antioxidant mechanisms of selected Asteraceae species. Special attention was given to their phytochemical contents—polyphenols, flavonoids, and essential oils—and their biological relevance to oral health. Results: OS plays a critical role in the onset and progression of oral conditions such as caries, periodontitis, gingivitis, aphthous ulcers, abscesses, precancerous lesions, and oral cancers. ROS and reactive nitrogen species (RNS) cause inflammation, tissue breakdown, and salivary gland dysfunction. Asteraceae plants like Matricaria chamomilla, Calendula officinalis, Cichorium intybus, Taraxacum officinale, Arctium lappa, Achillea millefolium, and Solidago virgaurea demonstrate notable antioxidant, anti-inflammatory, and antimicrobial properties that help counteract OS and support oral homeostasis. Conclusions: Asteraceae and Lamiaceae species show high therapeutic potential in addressing OS-related oral disorders. Their bioactive compounds aid in restoring redox balance and protecting oral tissues. These findings support the integration of phytotherapeutic agents into oral healthcare and call for further clinical validation of plant-based strategies for disease prevention and management.

Oral infections, caused by bacterial, fungal, and viral pathogens, are a significant source of dental morbidity and can lead to systemic complications, especially in immunocompromised individuals. Complex microbial interactions and host immune responses drive common conditions such as dental caries, periodontal disease, oral candidiasis, and herpetic lesions. Conventional antimicrobial therapies face limitations due to resistance and adverse effects, prompting interest in alternative treatments. Cannabidiol (CBD), a non-psychoactive compound derived from Cannabis sativa, has emerged as a promising candidate due to its antimicrobial, anti-inflammatory, and immunomodulatory properties. CBD targets various molecular pathways, including cannabinoid receptors, TRP channels, adenosine receptors, and PPARs, contributing to its multifaceted therapeutic effects. It has demonstrated efficacy against oral pathogens such as Streptococcus mutans, Enterococcus faecalis, and Candida albicans, disrupting biofilms and bacterial membranes. Additionally, CBD modulates inflammatory responses by reducing cytokine production and oxidative stress, particularly relevant in chronic conditions like periodontal disease. Emerging evidence also suggests synergistic effects with conventional antimicrobials and benefits in tissue regeneration. This review highlights the therapeutic potential of CBD in managing oral infections, offering a novel approach to overcoming current treatment limitations and guiding future research into safer and more effective oral health interventions.
