Prevalence of talon cusp: Systematic literature review, meta-analysis and new scoring system

Talon cusp is a developmental anomaly consisting of vertical ridge or projecting labially lingually from an anterior permanent primary tooth. A range prevalence between 0.06 % and 40.8 has been reported in the literature. Although many epidemiological studies have conducted, no synthesis these data performed to date. The aim this paper was determine talon investigate link sex cusp. systematic search undertaken using PubMed/Medline, Embase Cochrane Library electronic databases for publications 1981 2020 investigating sex. Three reviewers selected independently, extracted accordance with PRISMA statement, assessed risk bias via GRADE & approaches. From 39 potentially eligible studies, 9 were full text analysis 8 included meta-analysis, representing 35,224 participants. meta-analyses random model, calculating weighted-mean (at least one per individual) 1.67 %. Sex not statistically significantly associated our study (OR = 1.10; 95 CI [0.82–1.47]; p > 0.05). We report first provided by meta-analysis non-syndromic sample. non-statistically significant association relevant terms genetic etiology. In order improve homogeneity accuracy results further we propose new universal scoring system various clinical implications. Therapeutics may vary simple monitoring extraction supporting This condition occurs approximately population.
