Objective Methods Results Conclusion High‐risk human papillomaviruses (HPV) are an established cause of oropharyngeal cancer. Their relationship with oral cancer remains unclear with detection ranging from 0% to 100%. HPV DNA detection or evidence of exposure alone is insufficient to conclude causality. This systematic review assesses the extent of bias in studies of HPV detection in cancers of the oral cavity.PubMed, Ovid MEDLINE, EMBASE, and PsycInfo databases were searched for observational studies reporting the effect of HPV in oral cavity specific cancers.All 15 included studies presented HPV DNA detection or serum HPV‐antibodies, none included mRNA E6/E7 analysis. Cases with oral cancer had 5.36 times (95% CI 3.29–8.72) higher odds of having HPV detected compared to controls. The odds of HPV detection were higher in cell‐based (OR 6.93; 95% CI 0.82–58.55) and tissue samples (OR 5.28; 95% CI 3.41–8.18) than blood‐based samples (OR 3.36; 95% CI 1.53–7.40).When cancer site is clearly differentiated between oropharynx and oral cavity, 12 studies showed strong association between HPV and oral cancer, but the available estimates lack internal validity due to inconsistent measurements, high confounding, and lack of gold standard testing. There is not high‐quality evidence to conclude a causal relationship of HPV with oral cancer. [ABSTRACT FROM AUTHOR]

Introduction: Special needs dentistry (SND) is an emerging dental specialty, with ongoing developments in education and clinical practice focused towards the tailored management of individuals with special needs (SN). Patients with SN have a higher prevalence of oral diseases and unmet dental needs compared to the general population. Although inadequate training and experience in managing patients with SN has been highlighted as a significant barrier to accessing care, there is limited data about the extent of SND teaching at the entry‐to‐practice or higher levels. Methods: This work is the first to map SND curricula globally, across 180 countries and 1265 dental schools. Results: Although 74.62% of dental schools were found in developing economies, the distribution of programs that reported SND in their courses was highly skewed towards developed countries. In terms of advanced degrees, beyond basic entry‐to‐practice training, the USA delivered 60% of the SND programs, followed by Canada (15.56%), UK (13.33%), and Australia (8.89%). The term SND appeared in 33.95% of entry‐to‐practice level program curricula and was less commonly used in transitioning economies. Only 112 SND‐specialized practitioners enter the workforce globally each year from developed economies, and all but three advanced degrees are found in G7 countries. Conclusion: By exploring the impact of economic status on its distribution, this paper highlighted the lack of SND representation in dental curricula, especially amongst programs in transitioning or developing economies. Education of both general dentists and specialists is critical as a collaborative effort is needed to manage the growing population of patients with SN. [ABSTRACT FROM AUTHOR]

Objectives: Special needs dentistry (SND) is a vast and fragmented field of study. This comprehensive bibliometric analysis aimed to evaluate the scope of SND, including the existing knowledge base, distribution structure, quantitative relationships, and research trends. Material and Methods: A systematic search was conducted on March 10, 2022, using the Web of Science Core Collection database, covering the period from 1985 to 2021, focusing on studies reporting on special needs populations in a dentally relevant context. Records were title‐screened and analyzed for key bibliometric indicators. Results: Among 48,374 articles, 13,869 underwent bibliometric analysis. Peak SND research occurred during 1985–1997. United States led in productivity, trailed by Brazil and Japan. University of Sao Paulo excelled in Brazil, University of Washington and University of North Carolina in the United States. The Journal of Dental Research was the most productive source of research and also had the highest number of citations, followed by Community Dentistry and Oral Epidemiology. Keyword analysis revealed that "elderly", "caries", and "epidemiology" were the most commonly used author keywords. Conclusions: This study represents the first bibliometric analysis of SND literature. It emphasizes the need for increased collaboration between institutions and authors. Furthermore, it suggests focusing on research input from non‐dental disciplines and populations with rarer intellectual or developmental conditions. [ABSTRACT FROM AUTHOR]

Oral squamous cell carcinoma (OSCC) is the most common head and neck cancer. There is mounting evidence to suggest that several components of the coagulation system directly affect carcinogenesis. Our recent in vitro studies demonstrated, for the first time, that various anticoagulants have anticancer effects on OSCC. They also showed the need for the immediate translation of these experimental conditions from bench to preclinical animal models. Here, we carried out a systematic review to summarise existing evidence on murine models built around the interactions between anticoagulants and oral cancer. Only one preclinical murine study was included in our systematic review, investigating the role of heparins in tumour pathophysiology. The paucity of evidence regarding the interactions between oral squamous cell carcinoma and anticoagulants emphasises the urgency with which further preclinical research should be conducted.

Objective: To systematically identify and summarise current research on the utility of confocal microscopy in oral squamous cell carcinoma and oral epithelial dysplasia in oral potentially malignant disorders. Methods: Databases Medline, Embase, Evidence‐Based Medicine, and Web of Science were searched with articles screened and included if their primary objective was the use of a confocal microscope in diagnosis of oral cancer or epithelial dysplasia, in vivo or ex vivo. Results and Discussion: Twenty‐eight relevant studies were identified of which 21 studies included oral squamous cell carcinoma specimens. Fifteen studies included in vivo use. The studies included both qualitative and fluorescence confocal microscope and reflectance confocal microscope analysis along with quantitative analysis of carcinoma and dysplasia. Thirteen studies reported the predictive value of their confocal device in the diagnosis of dysplasia and carcinoma. The quantitative software‐based studies show promise in objectifying the diagnostic process for identifying abnormalities within the microstructure of the oral mucosa. Conclusions: There was heterogeneity in the criteria for diagnosis of dysplasia and oral squamous cell carcinoma with experience levels of assessors impacting method efficacy. Both qualitative and quantitative confocal assessment methodologies have been explored, the latter highlighting the potential of future machine‐augmented diagnostic precision. [ABSTRACT FROM AUTHOR]
