Nasal septum changes in adolescent patients treated with rapid maxillary expansion.

Objective: To analyze cone-beam computed tomography (CBCT) scans to measure changes in nasal septal deviation (NSD) after rapid maxillary expansion (RME) treatment in adolescent patients.

Methods: This retrospective study involved 33 patients presenting with moderate to severe nasal septum deviation as an incidental finding. Out of these 33 patients, 26 were treated for transverse maxillary constriction with RME and seven, who did not undergo RME treatment, were included in the study as control group.

Effect of non-surgical maxillary expansion on the nasal septum deviation: a systematic review.

Nasal breathing is a requirement for proper growth and development of the craniofacial complex. Inadequacy of the nasal airway from obstruction such as from nasal septal deviation (NSD) can affect craniofacial development. Further investigation of the possibility of rapid maxillary expansion (RME) correcting NSD would be valuable, considering the undesirable sequelae of NSD on nasal breathing, which can consequently affect craniofacial development.

Measurement tools for the diagnosis of nasal septal deviation: a systematic review.

Objective: To perform a systematic review of measurement tools utilized for the diagnosis of nasal septal deviation (NSD).

Methods: Electronic database searches were performed using MEDLINE (from 1966 to second week of August 2013), EMBASE (from 1966 to second week of August 2013), Web of Science (from 1945 to second week of August 2013) and all Evidence Based Medicine Reviews Files (EBMR); Cochrane Database of Systematic Review (CDSR), Cochrane Central Register of Controlled Trials (CCTR), Cochrane Methodology Register (CMR), Database of Abstracts of Reviews of Effects (DARE), American College of Physicians Journal Club (ACP Journal Club), Health Technology Assessments (HTA), NHS Economic Evaluation Database (NHSEED) till the second quarter of 2013. The search terms used in database searches were 'nasal septum', 'deviation', 'diagnosis', 'nose deformities' and 'nose malformation'.

Prediction of lower incisor proclination during Xbow treatment based on initial cephalometric variables.

Objective: To predict lower incisor proclination from initial cephalometric values in Class II division 1 patients treated in phase I with the Xbow appliance.

Materials And Methods: Two hundred forty-nine mild to moderate Class II division 1 patients treated with the Xbow appliance as a phase I treatment were considered. Patients were in late mixed dentition or early permanent dentition.

Dimensional stability of irreversible hydrocolloid impression materials as a function of pouring time: a systematic review.

Statement Of Problem: Pouring time of irreversible hydrocolloid impressions differs depending on the brand and intended use, either of which may result in variable dimensional stability.

Purpose: The purpose of this study was to investigate the available literature on dimensional stability of irreversible hydrocolloid impression materials as a function of pouring time and disinfectant solutions used.

Material And Methods: Three electronic database searches (Medline, PubMed, and EMBASE) were conducted to identify in vitro peer-reviewed studies published in English between the early 1970s and October 2010.

A comparison of anterior vs posterior isolated mandible fractures treated with intermaxillary fixation screws.

Objective: To compare complication rates after use of intermaxillary fixation (IMF) bone screws for anterior (ie, symphyseal/parasymphyseal) and posterior (ie, body and angle) mandible fractures.

Methods: A retrospective analysis of isolated mandible fractures treated with intraoperative IMF bone screws at 2 major level 1 trauma centers within the Department of Otolaryngology-Head and Neck Surgery at the University of Minnesota. From January 1, 2003, through January 31, 2006, we accrued 53 patients with 67 isolated mandible fractures treated with intraoperative IMF bone screws.

A systematic review of the association between appliance-induced labial movement of mandibular incisors and gingival recession.

Objective: To determine if an association exists between appliance-induced labial movement of mandibular incisors and gingival recession.

Methods: Electronic databases were searched for studies with the terms: 'incisor', 'incisor proclination', 'tooth movement', 'orthodontic tooth movement', 'gingival recession' and 'orthodontic appliance'. The original articles and abstracts that met the initial inclusion criteria were retrieved, and their references hand searched for possible articles missed by the database searches.
