Minimally invasive interventions such as silver diamine fluoride (SDF) and atraumatic restorative treatments (ARTs) have been recommended by the World Health Organization to control caries where evidence is lacking in older adults. This cluster-randomized clinical trial tested the noninferiority of SDF vs ART in caries arrest (primary) and prevention (secondary) at 52 wk. Older adults ≥62 y living in 33 subsidized housing facilities were enrolled at baseline, with follow-up visits at 26 and 52 wk. Participants in the intervention arm received biannual topical application of 38% SDF, and the control arm received ART with glass ionomer cement (+2.5% sodium fluoride varnish). Caries arrest and new caries were determined through examinations conducted by hygienists utilizing criteria from the International Caries Detection and Assessment System. The noninferiority margin was 10% of the effectiveness of the control treatment. Among a total of 568 enrolled participants (intervention: 18 sites, <jats:italic toggle=\"yes\">n</jats:italic> = 346; control: 15 sites, <jats:italic toggle=\"yes\">n</jats:italic> = 222), 51% were female and 66% were Black; the mean ± SD age was 69.6 ± 6.8 y. Caries arrest at 52 wk was 88% in the intervention arm vs 92% in the control arm (difference, −0.04; 95% CI, −0.08 to 0.01). After adjusting for sociodemographics, a linear model with generalized estimating equations yielded an estimated treatment difference of −0.05 (95% CI, −0.09 to −0.01). The mean number of new decayed/carious lesions at 52 wk was 0.67 ± 1.72 for the intervention arm and 0.66 ± 1.71 for the control arm (difference, 0.01; 95% CI, −0.31 to 0.32). Results for both outcomes indicated noninferiority of 38% SDF at 52 wk. Findings support the use of a simple topical biannual 38% SDF treatment to control caries in clinical and public health settings, which can be delivered by dental and medical clinicians (ClinicalTrials.gov NCT03916926).","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"1 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Public ambivalence toward fluoride has intensified in recent years, reflected in ongoing disputes over water fluoridation. This scoping review synthesizes qualitative evidence on how fluoride hesitancy is constructed and expressed across social and clinical contexts. Qualitative studies examining perceptions, beliefs, and decision-making related to fluoride use were identified through searches of PubMed, Scopus, Embase, and CINAHL to April 2025. Twelve studies met the inclusion criteria. Data were extracted using a standardized charting approach and synthesized through an inductive, grounded theory–informed thematic analysis supported by constant comparison and reflexive memoing. Five interconnected domains of hesitancy were identified: (1) perceptions of fluoride as harmful or toxic; (2) uncertainty about benefits or necessity; (3) mistrust of scientific, professional, or governmental institutions; (4) ethical concerns regarding autonomy, consent, and environmental integrity; and (5) discomfort with specific delivery modalities paired with preferences for alternatives. Hesitancy was shaped not only by information but also by emotional responses, lived experience, parenting norms, online discourse, and interpretations of institutional credibility. Across studies, decisions about fluoride reflected broader efforts to navigate uncertainty, protect children, and maintain control over health choices. Fluoride hesitancy is a multifaceted interpretive process rather than a simple knowledge deficit. Addressing it requires approaches that pair clear scientific communication with attention to trust, autonomy, and the social contexts in which preventive recommendations are received. Strategies that acknowledge experiential perspectives and increase transparency around policy decisions may enhance the credibility and uptake of fluoride guidance, but some degree of hesitancy is likely to persist given wider environments of uneven trust and contested information.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"10 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these interventional studies are not always feasible due to ethical, time, and cost constraints. Additionally, they are often criticized for not accurately representing patients seen in clinical practice. Observational studies can help bridge this gap, but they are often affected by several sources of bias. A growing framework known as target trial emulation (TTE) is increasingly being applied to real-world data to minimize these common biases in observational studies and, under certain conditions, allow for causal interpretation. In this study, we assessed the 5-y effect of thiazide monotherapy, an antihypertensive medication known to cause xerostomia, on the risk of developing dental caries. We applied the target trial framework to build a TTE cohort using an active comparator new user design. We compared thiazide vs nonthiazide monotherapy using electronic health records from the All of Us Research Program. Furthermore, we developed 2 naïve cohorts: a prevalent user cohort, which included existing medication users, and a nonaligned cohort, which was affected by immortal time bias. These cohorts helped illustrate the advantages of TTE. In the TTE cohort, we found no significant difference in the 5-y risk of dental caries between groups, with a risk difference of 0.29% (95% CI, −0.36% to 0.95%). In contrast, the naïve cohorts showed directionally opposite effects, with 5-y risk differences of 0.65% (95% CI, 0.22% to 1.09%) in the prevalent user cohort and −0.24% (95% CI, −0.55% to 0.07%) in the nonaligned cohort, highlighting the impact of design-related biases on the observed outcomes. We demonstrated how the TTE framework can help avoid common biases in observational research, enabling researchers to answer important oral health questions.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"84 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the 2 X-chromosomes is randomly selected for inactivation in each cell during embryogenesis and remains inactive throughout life.

However, it remains unclear how X-inactivation is involved in palate and tooth development. <jats:italic toggle=\"yes\">Ofd1</jats:italic> is located on the X-chromosome.

Cells with <jats:italic toggle=\"yes\">Ofd1</jats:italic> mutant X chromosome activation ( <jats:italic toggle=\"yes\">Ofd1</jats:italic> mutant cells) accumulated at the tip of the palatal shelves due to cell segregation caused by a lack of EFNB1 expression, resulting in a cleft palate in all <jats:italic toggle=\"yes\">Ofd1</jats:italic> <jats:sup>fl/WT</jats:sup> ; <jats:italic toggle=\"yes\">Wnt1Cre</jats:italic> (HET) mice.

Dysregulation of nitric oxide synthase (NOS) and consequent impairment of endogenous NO production have been implicated in a range of oral conditions. Accordingly, exogenous NO therapy has garnered significant interest due to its broad-spectrum antibacterial, potent anti-inflammatory, tissue-regenerative, and potential antitumor effects. This review provides a comprehensive overview of therapeutic advances in exogenous NO for dental and oral diseases, focusing on underlying mechanisms, such as modulation of the cyclic di-guanosine monophosphate pathway, mediation of S-nitrosylation, activation of the soluble guanylate cyclase–cyclic guanosine monophosphate–protein kinase G pathway, and regulation of the c-Jun N-terminal kinase/mitogen-activated protein kinase pathway. Collectively, these mechanisms confer antimicrobial efficacy, immunomodulation, enhanced periodontal and pulpal tissue repair, and apoptosis induction in oral cancer cells. Various NO delivery platforms, including nanocarriers, hydrogels, implant coatings, and microneedles, are reviewed for their efficacy and application in managing periodontitis, peri-implantitis, dental caries, endodontic and periapical diseases, oral ulcers, orthodontic tooth movement, and oral cancer. Although most of the current evidence is derived from preclinical studies and substantial challenges remain with respect to dosing accuracy and delivery specificity, the unique multitarget properties of exogenous NO highlight its considerable promise as an adjunctive strategy in dental medicine. This review seeks to provide a comprehensive overview that not only advances fundamental understanding of exogenous NO but also promotes its clinical translation for improved management of dental and oral diseases.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"37 1","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147465374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined heterogeneity in the association between tooth loss and mortality among older Japanese adults. Data were obtained from 69,265 individuals aged ≥65 y who participated in the 2013 wave of the Japan Gerontological Evaluation Study. Questionnaire survey responses were linked to mortality records from municipal registries for 9 y. The average treatment effect (ATE) of tooth loss (having <20 natural teeth) on all-cause mortality was estimated using a linear probability model with an inverse probability weighting estimator. Heterogeneity in the association was assessed by estimating conditional average treatment effects (CATEs) using the causal forest machine learning algorithm. A set of 44 covariates, including demographic, economic, social, health, and community-related factors, was incorporated as potential drivers of heterogeneity. During the follow-up period, 26.4% of participants with <20 teeth and 14.4% of those with ≥20 teeth died. Tooth loss was significantly associated with increased mortality risk by 3.2 percentage points after adjustment for covariates (average treatment effect = 0.032; 95% confidence interval, 0.023-0.040). A statistically significant heterogeneity in the estimated effects was observed (median CATE = 0.028; interquartile range = 0.010). Greater effects were identified among subgroups characterized by men, poor health status, and lower socioeconomic conditions. Heart disease, sex, and depression were the most influential contributors to this heterogeneity. Tooth loss was associated with mortality risk, with significant variation in the magnitude across population subgroups. Tooth loss may serve as an informative indicator of elevated mortality risk among older adults, particularly among vulnerable subgroups.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"35 1","pages":"220345251414360"},"PeriodicalIF":7.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147461759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we present MetaDent, a comprehensive resource that includes 1) a novel and large-scale dentistry image dataset collected from clinical, public, and web sources; 2) a semistructured annotation framework designed to capture the hierarchical and clinically nuanced nature of dental photography; and 3) comprehensive benchmark suites for evaluating state-of-the-art VLMs on clinical image understanding. Our labeling approach combines a high-level image summary with point-by-point, free-text descriptions of abnormalities. This method enables rich, scalable, and task-agnostic representations. We curated 60,669 dental images from diverse sources and annotated a representative subset of 2,588 images using this meta-labeling scheme. Leveraging large language models (LLMs), we derive standardized benchmarks: approximately 15,000 visual question answering (VQA) pairs and an 18-class multilabel classification dataset, which we validated with human review and error analysis to justify that the LLM-driven transition reliably preserves fidelity and semantic accuracy. We then evaluate state-of-the-art VLMs across VQA, classification, and image captioning tasks. Quantitative results reveal that even the most advanced models struggle with a fine-grained understanding of intraoral scenes, achieving moderate accuracy (e.g., less than 70% in VQA) and producing inconsistent or incomplete descriptions in image captioning. These findings underscore the gap between general-purpose VLMs and the demands of specialized models, highlighting the need for domain-adapted training and more sophisticated evaluation protocols to assist professional dental practice and community oral health efforts.

These changes are often detected histologically in potentially malignant disorders and are associated with an increased risk of malignant transformation into oral squamous cell carcinoma (OSCC). Currently, clinicians rely mainly on the pathologist's histological gradings (binary or tertiary grading systems) to determine the follow-up protocol for patients with OED. However, both histological gradings are rather subjective and not highly reliable. Therefore, there is a need for biomarkers to distinguish high-risk OED cases from low-risk cases. Twelve oral tongue dysplasia samples were collected for multiplex immunostaining. The samples were derived from 7 patients who did not develop OSCC within 5 y of their OED diagnosis (low-risk group, LR) and 5 patients who developed OSCC (high-risk group, HR). Ten antibodies targeting epithelial cells, immune cells, a proliferation marker, and immune checkpoints were used (PanCK, CD4, CD8, CD11b, CD68, CD56, FoxP3, Ki67, PD-1, PD-L1). Uniform manifold approximation and projection generated from multiplex staining revealed distinct differences in the distribution of immune cells and immune checkpoint expression between the LR and HR groups. The HR group showed a higher number of CD8+ cytotoxic T cells and CD68+ macrophages than the LR group. Notably, both PanCK+ epithelial cells and CD8+ cytotoxic T cells exhibited increased proliferation in the HR group, as indicated by Ki67 expression. Additionally, PD-1 expression was significantly elevated in the HR group. The logistics regression model further confirmed the predictive value of individual markers and identified a multimarker model with superior predictive performance. Our multiplex immunostaining revealed significant differences in the immune landscape between LR and HR cases of OED dysplasia. CD8+ cytotoxic T cells, CD68+ macrophages, and PD-1+ cells may serve as potential biomarkers for stratifying HR from LR oral tongue dysplasia cases.","PeriodicalId":15596,"journal":{"name":"Journal of Dental Research","volume":"10 1","pages":"220345251414354"},"PeriodicalIF":7.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147461777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
