Distinctive genes and signaling pathways associated with type 2 diabetes-related periodontitis: Preliminary study.

The biological mechanisms underlying the pathogenesis of type 2 diabetes (T2DM)-related periodontitis remain unclear. This cross-sectional study evaluated the distinctive transcriptomic changes between tissues with periodontal health and with periodontitis in patients with T2DM. In this cross-sectional study, whole transcriptome sequencing was performed on gingival biopsies from non-periodontitis and periodontitis tissues from non-diabetic and diabetic patients.

Association between low fluoride exposure and children's intelligence: a meta-analysis relevant to community water fluoridation.

Objectives: Previous meta-analyses have mainly focused on studies conducted in endemic fluorosis areas with relatively high fluoride concentrations. These are impoverished rural communities in China, India, and Iran, and the findings cannot be generalised to developed countries. Therefore, we investigated the association between fluoride concentrations relevant to community water fluoridation and children's cognition measured with IQ scores by synthesising effect sizes reported in observational studies.

High sugar intake from sugar-sweetened beverages is associated with prevalence of untreated decay in US adults: NHANES 2013-2016.

Objectives: To assess the association between sugar from sugar-sweetened beverages (SSBs) and untreated decay in permanent teeth and calculate the cost burden of sugar from SSBs on untreated decay in US adults.

Methods: Cross-sectional data from the 2013-2014 and 2015-2016 cycles of the National Health and Nutrition Examination Survey (NHANES) were analysed in 2020 (n = 9001 adults aged ≥20). Multivariable analyses assessed sugar intake from SSB consumption with the presence of untreated decay in permanent teeth and number of untreated decayed teeth.

Cross-sectional study on the quality of oral lichen planus videos on YouTube™.

Background: YouTube™ is one of the most used platforms for patients looking for health-related information. The purpose of this cross-sectional study was to analyze the available information about oral lichen planus on YouTube™ and how users interact with it.

Methods: A YouTube™ search for oral lichen planus was performed, setting English UK (language) and United Kingdom (country).

Measurement of Oral Epithelial Thickness by Optical Coherence Tomography.

Optical coherence tomography (OCT) is a real-time, in-situ, non-invasive imaging device that is able to perform a cross-sectional evaluation of tissue microstructure based on the specific intensity of back-scattered and reflected light. The aim of the present study was to define normal values of epithelial thickness within the oral cavity. OCT measurements of epithelial thickness were performed in 28 healthy patients at six different locations within the oral cavity.

Does water fluoridation affect the prevalence of enamel fluorosis differently among racial and ethnic groups?

Objectives: There are reports showing higher prevalence of enamel fluorosis among African-American children. This study was conducted to assess whether the effect of water fluoride level on enamel fluorosis is different among different race/ethnicity groups among US school children.

Methods: Data from the National Survey of Oral Health of US School Children 1986-1987 were analyzed to determine the prevalence of enamel fluorosis among 7-17 year-old children.

Survey of dentists to determine contemporary use of endodontic posts.

Statement Of Problem: Although the scientific literature provides sound decision-making tools for the restoration of endodontically treated teeth, dentists have different opinions on the rationale for the use of endodontic posts (dowels) and selection of post systems. The decision to place a post is at times contrary to the literature. Updated information on the treatment of endodontically treated teeth among general dentists is lacking.
