Effect of tube debonding on the enamel surface in vitro : Evaluation with optical coherence tomography.

Objective: In vitro evaluation of the morphology of the enamel surface before bonding metal tubes and after debonding using spectral domain optical coherence tomography (SD-OCT) and light microscopy.

Methods: In all, 40 extracted caries-free human molars without defects were selected and cleaned. The tooth surfaces were imaged by light microscopy and SD-OCT prior to the placement of metal tubes (Titanium Orthos; Ormco, Brea, CA, USA).

Perception of facial and dental asymmetries and their impact on oral health-related quality of life in children and adolescents.

Background: The aim of this study was to investigate the perception of facial and dental asymmetries in children and adolescents and how these asymmetries affect their psychosocial and emotional well-being.

Methods: The study included 66 children and adolescents (7-15 years) with a deviation between the maxillary and mandibular dental midlines of > 0.5 mm.
