One-year clinical evaluation of class II bulk-fill restorations in primary molars: a randomized clinical trial.

This double-blind, randomized clinical trial aimed to compare the clinical performance and clinical time to restore occluso-proximal cavities in primary molars withbulk-fillresin and conventional resin. A total of 140 class II restorations in primary molars of 65 participants (mean age of 6.7 + 1.

Evaluation of the Use of Potassium Iodide Application on Stained Demineralized Dentin Under Resin Composite Following Silver Diamine Fluoride Application.

The purpose of this study was to assess the effect of potassium iodide (KI) after applying silver diamine fluoride (SDF) on the staining of demineralized dentin covered or not by a composite resin layer. Dentin blocks from 30 bovine incisors were demineralized and randomly allocated in three groups (N equals 10): (1) control (no treatment); (2) treated with SDF; and (3) treated with SDF and KI. Half of the specimens of each group received a composite resin restoration immediately after treatment.

Etching time and bonding of adhesive systems to dentin of primary teeth: A systematic review and meta-analysis.

Background: Due to the chemical and morphological differences between primary vs. permanent teeth, the time reduction of the acid etching or acidic primer can result in higher values of bond strength.

Aim: To assess through a systematic review and meta-analysis the influence of the reducing etching (acid etching or acidic primer) time on the bond strength of adhesive systems to primary dentin.

Oral health status of schoolchildren living in rural and urban areas in southern Brazil.

This study assessed the effect of area of residence (rural vs. urban) on dental caries experience among southern Brazilian schoolchildren. This cross-sectional survey was conducted in Rosário do Sul, southern Brazil, and included 373 9-14-year-old schoolchildren attending public municipal schools (122 living in the rural area, and 251, in the urban area).
