The effect of facemask in patients with unilateral cleft lip and palate: a systematic review and meta-analysis.

Background: Patients with cleft lip and palate usually present a Class III skeletal pattern. Facemask (FM) is one of the conventional orthodontic treatment modalities used to address the skeletal discrepancy in cleft patients.

Objective: To investigate the potential effectiveness of FM in unilateral cleft lip and palate (UCLP) patients.

NAM Therapy-Evidence-Based Results.

Many orthodontists working on patients with cleft lip and palate (CLP) have shown great enthusiasm for presurgical infant orthopedics (PSIO) to improve surgical outcomes with minimal intervention. Even though every clinician aims to use the best treatment modality for their patients, PSIO effects can be confounded by surgical type and timing of the primary repair, as is discussed in many studies. In such cases, one should be cautious when evaluating the particular outcomes for patients with CLP since it is difficult to differentiate the sole effect of an individual surgical or orthodontic intervention.

In vivo evaluation of tooth colour alterations during orthodontic retention: A split-mouth cohort study.

Objectives: To assess in vivo colour alterations of teeth following removal of fixed orthodontic appliances during retention.

Setting And Sample Population: The Department of Orthodontics at the Aristotle University of Thessaloniki. Forty-eight patients after orthodontic treatment.

In vitro spectrophotometric evaluation of Vivera clear thermoplastic retainer discolouration.

Aims: To investigate the in vitro effect of different staining solutions on the colour stability of Vivera retainers.

Methods: Thirty flat specimens fabricated using the Vivera material (Align Technology Inc., CA, USA) were assigned into five Groups (A, B, C, D and E) and immersed at 37 degrees C in solutions of distilled water (control), coffee, tea, red wine, and Coca-Cola.

Root resorption of endodontically treated teeth following orthodontic treatment: a meta-analysis.

Objective: The aim of this meta-analysis was to investigate the effect of orthodontic treatment on root resorption of endodontically treated teeth compared to vital teeth.

Materials And Methods: A literature search was conducted in 18 electronic databases. Review articles and relevant articles were searched for cross-references.

Transmigration of impacted canines: prevalence, management and implications on tooth structure and pulp vitality of adjacent teeth.

The aim of this study was to estimate the prevalence of transmigrant canines in a sample of panoramic radiographs of a random Greek population, to classify them and evaluate clinically and radiographically all the implications for adjacent teeth. Panoramic radiographs of 3,586 patients retrieved from eight private practices between 1998 and 2009, were examined. Panoramic radiographs with extracted canines were not included in this study.
