Although both appliances were successful in correcting the skeletal Class II malocclusion, the skeletally anchored Forsus FRD EZ appliance did so without protruding the mandibular incisors.

Objective: To test the null hypothesis that there were no significant differences for pharyngeal airway volumes between the adolescent patients affected by bilateral cleft lip and palate (BCLP) and well-matched controls using cone beam computed tomography. Materials and Methods: The study sample consisted of 16 patients (11 female and 5 male; mean [SD] age 14.1 [2.1] years) affected by BCLP and 16 patients (10 female and 6 male; mean [SD] age 13.4 [2.0] years) as age-and sex-matched control group. Craniofacial measurements and pharyngeal airway dimension, area, and volume measurements of patients in both groups were calculated and statistically examined using Student's t-test and multiple linear regression analyses. Results: Statistically significant differences were found between the BCLP and control groups for SNB (P , .05), SN-GoGn (P , .05), Co-A (P , .05), PAS (P , .01), minAx (P , .01), and oropharyngeal airway volume (P , .05). The most predictive variables for oropharyngeal airway volume were found as PAS (r 5 .655 and P 5 .000) and minAx (r 5 .787 and P 5 .000). Conclusions: The null hypothesis was rejected. Oropharyngeal (P , .05) and total (P . .05) airway volumes were found to be less in the BCLP group, and thus the treatment choice in these patients should have positive effects on the pharyngeal airway.

The present study provides new information on the literature concerning the identification of the anatomical structure of NPC. This finding may assist clinicians in understanding the morphology and preventing possible complications in this region.

BackgroundDiscision method may provide an alternative to the piezocision approach in accelerated orthodontic treatment. The purpose of this study was to investigate the efficacy of discision on accelerated orthodontic tooth movement in comparison to the piezocision method in moderate crowding Angle Class I malocclusions.MethodsThirty-five female individuals were included in this clinical study. The participants were classified into three groups as conventional fixed non-extraction orthodontic treatment only (OT, n = 14), piezocision in addition to fixed non-extraction orthodontic treatment (PG, n = 9), and discision in addition to fixed non-extraction orthodontic treatment (DG, n = 12). The piezocisions and discisions were performed 1 week after placement of bonding brackets. The patients were seen at 2–3 week-intervals. Initial Little’s irregularity index scores were recorded from dental casts. Periodontal parameters were measured initially, after the 1-month orthodontic treatment. Probing pocket depth, bleeding on probing, plaque index, and gingival index were recorded. Visual analog scale (VAS) was performed over the first month at different times following the bracket bonding for pain assessment. The total orthodontic treatment duration was noted.ResultsThe duration of orthodontic treatment was statistically decreased in PG and DG compared to OT (P = 0.003). There was no statistical difference between PG and DG in orthodontic treatment duration (P > 0.05). There was no statistical difference between the two experimental groups in terms of VAS and periodontal parameter values (P > 0.05).ConclusionsThis is the first clinical orthodontic study to assess the effect of discision on the rate of orthodontic tooth movement. Discision is comparable to piezocision in terms of tooth movement acceleration, pain level, and periodontal status. The discision seems to be effective in reducing the time of orthodontic treatment.

Objective: The aim of the present study was to evaluate the content and quality of the popular videos on YouTubeTM about the treatment of cleft lip and palate. Design: Retrospective, YouTubeTM video analysis. Methods: The 3 keywords “cleft lip and palate surgery,” “cleft lip and palate treatment,” and “cleft lip and palate repair” were searched on YouTubeTM. After sorted by view-count, final 50 videos were analyzed for general characteristics, primary purpose, information content, relevance, audiovisual quality, and also viewers’ interaction index, and viewing rate formulas were calculated for each video. Kruskal Wallis and one-way analysis of variance tests were used to compare the video parameters between good, moderate, and poor information content videos. Results: The viewing rate was significantly higher in good content videos ( P = .003). Most of the videos were uploaded by a clinic (32%), a surgeon (20%), or individuals (22%) who shared their own experience. Most of the videos (54.00%) were classified as moderate general information content and 26.00% were rated as poor, and 20.00% were rated as good. Videos generally involved patient information (60.00%), followed by patient parent’s experience (14.00%), and cleft lip and palate surgery (12.00%). The average viewers’ interaction index of all evaluated YouTubeTM videos was 0.36. Conclusions: Although most of the videos were rated as moderate regarding the sufficiency of the information, the results of this study showed that YouTubeTM could still not be considered as a fully reliable source of information for patients on treatment of cleft lip and palate.
