Long-term effects of orthodontic interceptive expansion treatment : A retrospective study.

Purpose: The aim of this retrospective cohort study was to evaluate the long-term effects of interceptive orthodontic treatment with a removable expansion plate, based on transversal, sagittal, and vertical parameters.

Methods: A total of 90 patients needing interceptive treatment due to a crossbite or space deficiency were included. Records consisting of clinical photos, radiographs, and digital dental casts were collected for evaluation at two time points: the start of interceptive treatment (T0) and the start of comprehensive treatment (T1).

Hemoglobin A1c and preoperative glycemia as a decision tool to help minimise sternal wound complications: a retrospective study in OPCAB patients.

Background: Poor glycemic control has been associated with an increased risk of wound complications after various types of operations. However, it remains unclear how hemoglobin A1c (HbA1c) and preoperative glycemia can be used in clinical decision-making to prevent sternal wound complications (SWC) following off-pump coronary artery bypass grafting (OPCAB).

Methods: We conducted a retrospective study of 1774 consecutive patients who underwent OPCAB surgery between January 2010 and November 2016.

The evolution of self-esteem before, during and after orthodontic treatment in adolescents with dental malocclusion, a prospective cohort study.

Objectives: This study aimed (1) to investigate the evolution of self-esteem through orthodontic treatment, and (2) to study how key demographic factors would affect these evolutions and to assess relationships between self-esteem and orthodontic treatment need.

Methods: This longitudinal prospective cohort study comprised of 326 adolescents (172 girls and 154 boys) aged 11-16 years; data were obtained from 325 adolescents at T0 and 123 at T2. Three hundred twenty-one adolescents filled in questionnaires at T0, whereas 118 at T2.
