This collection explores the evolving landscape of dentistry and oral medicine, focusing on everything from cavity prevention and gum health to complex surgical procedures and systemic links between the mouth and the rest of the body. We translate these critical medical advances into clear, accessible insights so that both specialists and curious readers can understand the latest breakthroughs without getting lost in dense technical language.
Every new preprint in this category originates from medRxiv, where researchers share their findings before formal publication. Gist.Science processes each of these submissions immediately, generating both straightforward plain-language overviews and detailed technical summaries to ensure you get the full picture of the research. Below are the latest papers in dentistry and oral medicine, updated regularly as new studies emerge from the medRxiv server.
This systematic review and meta-analysis of 11 studies involving 2,847 patients reveals that orthodontic traction for impacted maxillary incisors has a pooled success rate of 82.3%, with significantly better outcomes associated with younger age (<14 years) and milder impaction depth (<5mm).
This study presents a proof-of-concept framework that integrates experimental antimicrobial susceptibility testing of oral *E. coli* with Particle Swarm Optimization and a surrogate Random Forest model to mathematically optimize hypothetical fluoride toothpaste formulations, while explicitly acknowledging that the current results require extensive experimental validation due to limited training data.
This in vitro study concludes that the Samsung Galaxy S23 Ultra, when used with a stabilization system, offers linear measurement precision comparable to a DSLR camera for dental photography, while the iPhone 15 Pro Max showed minor discrepancies, though the findings' clinical applicability is limited by the controlled experimental setup.
This cross-sectional study of children in Kano, Nigeria, reveals an unexpected predominance of *Staphylococcus aureus* over conventional pathogens like *Streptococcus mutans* in the salivary microbiome of those with Early Childhood Caries, suggesting a complex, multifactorial etiology that challenges existing caries paradigms in sub-Saharan Africa.
This international survey reveals that while dental educators hold positive views on the educational value of Extended Reality for enhancing anatomy understanding and clinical skills, its widespread integration is currently hindered by structural barriers such as high costs, limited technical support, and time constraints.
This comprehensive systematic review and meta-analysis establishes an evidence-based framework for managing mechanically impacted canines through orthodontic traction, demonstrating that while open and closed surgical exposure techniques yield comparable success rates, open exposure offers shorter treatment duration and lower ankylosis risk, whereas closed exposure provides superior patient comfort, all while emphasizing the critical need to differentiate mechanical impaction from primary failure of eruption to guide genetically informed clinical decision-making.
This systematic review and meta-analysis of 12,719 Nigerian children and adolescents found that while fluoridated toothpaste use is widespread, it is significantly associated with a 16% reduction in dental caries odds primarily in urban and rural settings, with the protective effect varying by residential location and baseline caries severity.
This study identifies a distinct salivary dysbiosis characterized by an enrichment of periodontal anaerobes and a loss of nitrate-reducing commensals that aligns with a specific olfactory-cognitive phenotype of aging, suggesting a non-invasive, microbiome-based approach for monitoring oral-brain axis health.
