Do Patients with Extrinsic Black Tooth Stains Have a Lower Dental Caries Experience? A Systematic Review and Meta-Analysis.

Studies have suggested that individuals affected by extrinsic black tooth stains have less dental caries experience in comparison to those without this condition. The aim of the present study was to perform a systematic review and meta-analysis to determine whether there is scientific evidence demonstrating that extrinsic black stains are a protective factor for the occurrence of dental caries. This systematic review was developed in accordance with the PRISMA statement and the research question was determined using the PECO strategy.

Association between developmental defects of enamel and celiac disease: A meta-analysis.

Objectives: Studies have observed the presence of extra-intestinal manifestations of celiac disease (CD), including involvement of the oral cavity, such that developmental defects of enamel (DDE) occur. Thus, the aim of this review was to access the polled prevalence of DDE in individuals with CD, and to establish the strength of the association between these two variables.

Methods: To carry out the systematic review, four electronic databases and the Grey Literature were searched, complemented by a manual search of reference lists within the selected articles.
