Arresting Active Carious Lesions Using Minimal Intervention Dentistry among a Group of Preschool Children: A Randomized Controlled Clinical Trial.

Objectives: This clinical trial investigated the effectiveness of three minimal intervention dentistry protocols in arresting dentin caries in primary molars of preschool children. Treatment time, anxiety in children, adverse events, and parents' esthetic perception were all assessed.

Materials And Methods: One hundred thirty-five 3-5-year-old children with active dentin caries lesions on the occlusal surface of primary molars were randomly allocated to the control group receiving atraumatic restorative treatment (ART) and two test groups receiving 38% silver diamine fluoride (SDF) or ultraconservative treatment (UCT).

Cleaning Efficacy of Toothpastes With Varying Abrasiveness-An In Vitro Investigation on Bovine Dentin.

Objective: To determine how differences in abrasiveness (RDA) influence cleaning capabilities of toothpastes.

Methods: For this in vitro trial, 60 bovine dentin samples were prepared and divided into six groups (G1-G6; n = 10). Groups G1-G5 were arranged in order from low to high toothpaste abrasiveness (G1: RDA: 12, G2: RDA: 29, G3: RDA: 43, G4: RDA: 71, and G5: RDA: 143).

In-Vitro Tooth Cleaning Efficacy and Filament End Rounding of Different Manual Children's Toothbrushes.

Purpose: This in-vitro study aimed to investigate the cleaning efficacy of 18 different manual children's toothbrushes applying horizontal, vertical, and rotational movements, as well as to evaluate the rounding of their filament ends.

Materials And Methods: Models equipped with artificial teeth (coated with titanium dioxide) were brushed using a brushing machine with clamped manual children's toothbrushes. The machine carried out horizontal, vertical, and rotational movements for 1 min with a constant contact pressure of 100 g.

Adhesion of tooth fragment after trauma: effect of adhesion strategy and storage in the rescue box.

This study aims to investigate the impact of storage conditions for crown fragments (specifically, whether they were stored within a tooth rescue box or in tap water) on their adhesion to fractured teeth when subjected to two different adhesive systems (namely, total etch and self etch). Sixty maxillary premolars were sectioned to obtain tooth fragments. These fragments were stored briefly (2 hours) and reattached in the following groups: Group 1 (fragments stored in tooth rescue box and reattached with etch and rinse (E&R) technique), Group 2 (fragments stored in tap water and reattached with E&R technique), Group 3 (fragments stored in tooth rescue box and reattached with self-etch (SE) technique), and Group 4 (fragments stored in tap water and reattached SE technique).
