Objective: To evaluate the bacterial contamination of different brands of Gutta-Percha (GP) points routinely used in clinical practice and the efficacy of a chairside disinfection protocol with sodium hypochlorite.
Methods: GP points (n=240), in sizes A, B, C, D, K15, K20, K25, K30, K35, K40, F1, F2, F3 (Dentsply®, Proclinic®, ProTaper® and R&S®), were randomly sampled from commercial packages already in use. These were added directly to Fluid Thioglycolate Medium (one GP point per tube) and incubated at 37ºC for 21 days.
Purpose: To assess the association between low prenatal or childhood levels of 25-hydroxyvitamin D (25(OH) D) and dental caries experience in children.
Materials And Methods: PubMed, B-On, Web of Science, Scopus, and Cochrane Library databases were searched. The inclusion criteria were randomised controlled trials, cohort and cross-sectional studies published between 1998 and 2019; caries outcomes expressed as prevalence or based on the decayed missing and filled index for primary and permanent teeth/surfaces; and vitamin D levels assessed by laboratory analysis.
