The effect of preprocedural mouthrinses against COVID-19 before acid etching on the microleakage of a resin-based sealant in permanent molars: An experimental study.

Aim: To determine whether rinsing with preprocedural mouthrinses against coronavirus disease before acid etching affects resin-based sealant microleakage.

Materials And Methods: A presented experimental study was performed on 15 extracted permanent third molars. Samples were randomly allocated into five groups: Group 1-distilled water (control); Group 2-1% hydrogen peroxide; Group 3-1.

The effect of casein phosphopeptide toothpaste versus fluoride toothpaste on remineralization of primary teeth enamel.

This study evaluated the effect of a CPP-containing toothpaste and compared it with fluoride-containing toothpastes on remineralization of caries-like lesions in primary teeth enamel, using polarized light microscopy. Forty-eight sound primary incisors were coated with nail varnish, leaving two 1x1 mm windows before being placed in a demineralizing solution for 4 days. After demineralization, all the specimens were coated with nail varnish over one window and were randomly assigned to 4 groups (A to D; n = 12).

A 6-month comparison of toothbrushing efficacy between the horizontal Scrub and modified Bass methods in visually impaired students.

Objective: The aim of this study was to compare the efficacy of the horizontal Scrub and modified Bass methods of toothbrushing in visually impaired students for 6 months.

Methods: Sixty visually impaired students, aged 10-12 years, were recruited to a randomized controlled clinical trial. At baseline, plaque index (PI) and gingival index (GI) were assessed, and then subjects were randomly divided into the horizontal Scrub and modified Bass groups.
