Piriform Rim Asymmetry in Unilateral Cleft Lip and Palate Patients Before Orthognathic Surgery.

Background: Complete unilateral cleft lip and palate (UCLP) creates a continuity defect on the nasal floor, which contributes to nasal asymmetry. Traditionally, piriform rim symmetry has been evaluated by comparing cleft and noncleft sides. No study has compared the magnitude of perinasal asymmetry in UCLP patients with a control group of patients without clefts.

A Qualitative Analysis of Treatment Patterns for Mild and Severe Molar Hypomineralization in Permanent Teeth: A Systematic Review.

Using a systematic review to answer the following question: What are the treatment patterns for mild and severe molar hypomineralization in permanent teeth? Electronic searches were conducted to identify randomized clinical trials (RCT) that related treatment to molar hypomineralization- (MH) affected permanent molars in children from five to 16 years old. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool, were performed for all included studies. Studies were selected according to PICOS criteria.

Three-segment versus 2-segment surgically assisted rapid maxillary expansion.

Objective: To compare the 2 surgically assisted rapid maxillary expansion (SARME) techniques, the conventional 2-segment osteotomy between maxillary central incisors and the 3-segment osteotomy between maxillary lateral incisors and canines bilaterally. Authors hypothesized that the 3-piece would provide better bone expansion.

Study Design: A pilot study was conducted; 19 patients were divided into 2 groups: conventional 2-segment osteotomy (10 patients) and 3-segment osteotomy (9 patients).

Impact of orthognathic surgery on quality of life and comparison of patients' postoperative experience after single- and double-jaw surgery: a longitudinal study.

Objective: To evaluate the impact of orthognathic surgery on quality of life (QoL) and to compare single- and double-jaw surgeries in terms of ratio and patient perceptions of the postoperative period.

Study Design: A prospective, longitudinal observational study was conducted. The short form Oral Health Impact Profile (OHIP-14) and the Orthognathic Quality of Life Questionnaire (OQLQ) were applied preoperatively and 6 months postoperatively to evaluate oral health-related QoL (OHRQoL).
