Oral health-related quality of life of children before, during, and after anterior open bite correction: A single-blinded randomized controlled trial.

Introduction: One of the goals of malocclusion treatment is to improve the oral health-related quality of life (OHRQoL) of patients. The aim of this trial was to assess the OHRQoL of children before, during, and after anterior open bite (AOB) correction, compared with nontreated children, in a 2-arm parallel single-blind randomized controlled trial.

Methods: Eighty children with AOB aged 8-10 years were randomly assigned to 2 groups (n = 40 each): a group treated with the use of fixed palatal crib (FPC; TG) and a control group (nontreated; CG).

Evaluation of black spaces between maxillary central incisors by dentistry students and laypeople.

This study aimed to compare the perception of smile esthetics and alterations among dentistry degree students and laypeople to identify differences in the esthetic perception of black spaces between the maxillary central incisors among Turkish laypeople and students in different study years. Photographs altered to include black spaces of various sizes at the midline were evaluated by 208 dentistry students in years 1-5 and 45 Turkish laypeople. Perceptional differences in different photographs were statistically significant.

Nonsurgical treatment of severe Class II malocclusion with anterior open bite using mini-implants and maxillary lateral incisor and mandibular first molar extractions.

This clinical case report presents the nonsurgical orthodontic treatment of a patient with skeletal Class II malocclusion, posterior crossbite, anterior open bite, accentuated dental discrepancies in both arches, and an odontoma.

A 22-year follow-up of the nonsurgical expansion of maxillary and mandibular arches in a young adult: Are the outcomes stable, relapsed, or unstable with aging?

Adult maxillary and mandible arch expansion without a surgical approach can be uncertain when long-term stability is considered. This case report describes the treatment of a 19-year-old woman with an Angle Class I malocclusion with constricted maxillary and mandibular arches. The patient's main complaint was mandibular anterior crowding.
