Evaluation of enamel surface integrity after orthodontic bracket debonding: comparison of three different system.

Objective: This study aimed to evaluate enamel surface integrity and time consumed during residual cement removal after bracket debonding using different adhesive removal burs with and without a dental loupe.

Material And Methods: Sixty human-extracted premolars were collected, cleaned, mounted, and prepared for orthodontic bracket bonding. Teeth were randomly divided into three main groups (n = 20) based on the adhesive removal method: tungsten carbide system (TC), sof-lex discs system (SD), and diamond system (DB) groups.

Growth-related nasal stability following unilateral complete cleft lip repair: A comparison of the standard and modified rotation-advancement technique.

Background: Improving growth-related nasal stability is a critical goal of primary cleft lip repair. The purpose of this study was to evaluate the growth-related stability of the nose after unilateral complete cleft lip (UCCL) repair with standard rotation-advancement (RA) and modified rotation-advancement (MRA) techniques.

Material And Method: In this retrospective study, 52 non-syndromic (UCCL) patients were treated with a MRA technique, where a C-flap and a superiorly based advanced flap were used to lengthen and support the columella and nasal sill, and 48 patients were treated with a standard RA technique.
