“…Because CBCT has been shown to be a reliable method for assessing dehiscences and fenestrations, we decided to use these images in cleft patients, a technique that has not been reported previously. Consistent with previous studies 4,5,[18][19][20][21][22][23][24] showing the high reliability of CBCT for 2-D and 3-D measurements, agreement was 100% for the detection of dehiscences and fenestrations. Although Sun et al 12 reported that this method might overestimate the actual measurements, the technique was reported to have the highest sensitivity and diagnostic accuracy for detecting various periodontal defects.…”

Objective: To evaluate the presence of dehiscence and fenestration defects around anterior teeth in the cleft region and to compare these findings with the noncleft side in the same patients using cone beam computed tomography (CBCT). Materials and Methods: CBCT scans of 44 patients (26 males, 18 females; mean age, 14.04 6 3.81 years) with unilateral cleft lip and palate (UCLP) were assessed to define dehiscences and fenestrations of the anterior teeth in both cleft and noncleft sides of the UCLP patients and a control group of noncleft patients (51 patients; 21 males, 30 females; mean age, 14.52 6 1.16 years). Data were analyzed using Pearson's x 2 and Student's t-test. Results: The prevalence of dehiscences at the maxillary central incisors, lateral incisors, and canines teeth were 43.2%, 70.6%, and 34.1% on the cleft side and 22.7%, 53.1%, and 27.3% on the noncleft side of UCLP patients, and 13.7%, 7.8%, and 13.7% in controls, respectively (statistically no difference between the sides of cleft patients). The cleft patients had a statistically significantly higher prevalence of dehiscences than did the controls on both the cleft and noncleft sides (P , .05), except for the maxillary central incisors. Fenestrations for these teeth were significantly more common on the cleft side in UCLP patients compared with controls (P , .05), whereas the difference for maxillary lateral incisors was not statistically significant. Conclusions: Patients with UCLP showed a higher prevalence of dehiscence and fenestration defects around the maxillary anterior teeth. (Angle Orthod. 2016;86:431-436.)

“…Current correlation analysis showed an inverse correlation between NA and the mandibular plane angle in the RH-HD group, consistent with Freitas et al, 23 who found that vertical growth patterns influenced upper airway dimensions. Confirming this point, Celikoglu et al 24 found that the nasopharyngeal and oropharyngeal airway volume were significantly higher in the low-and normal-angle groups than in the high-angle group. Ucar and Uysal 16 also reported a decrease in nasopharyngeal airway space from low-angle to normal-to high-angle cases.…”

The aim of this study was to investigate the effects of reverse headgear (RH) on pharyngeal airway morphology in two groups of Class III patients with different vertical craniofacial features in comparison with an untreated Class III group. Seventeen subjects (9 males, 8 females; mean age 11.3 ± 0.98 years) with optimum vertical growth and 17 subjects (10 males, 7 females, mean age 11.5 ± 1.1 years) with a vertical growth pattern treated with a removable intra-oral appliance and a Delaire type facemask were included. An untreated Class III control group of 11 subjects (8 males, 3 females, mean age 9.1 ± 1.1 years) was included to compare the treated groups. The paired t-test for intragroup and one-way ANOVA for intergroup comparisons were performed. The relationships between changes in the craniofacial morphology and airway were assessed by Spearman correlation analysis. The airway dimensions at the adenoid side and soft palate were increased in the treatment groups compared to the control group (p < 0.05). The nasopharyngeal area demonstrated a significant difference in normodivergent and control subjects (p < 0.05). No significant difference was found in the airway morphology due to different vertical features. The effect of RH treatment on the sagittal airway dimensions revealed no significant difference between different vertical craniofacial features in the short term.

“…Oktay and Ulukaya 10 also reported that the changes in the pharyngeal measurements of patients aged 11.7 years for a duration of 8 months were at a negligible level. In addition, future prospective studies using cone-beam computed tomography images with larger study samples could provide accurate findings and provide an opportunity for clinicians to compare their findings with ours because those images were reported to have several advantages [28][29][30][31] when compared with the conventional cephalometric films. Thus, the findings of the present prospective clinical study should be assessed within the limitations of the two-dimensional radiography design used for the assessment of the pharyngeal airway.…”

Objective: To evaluate the changes in pharyngeal airway dimensions and the position of the hyoid bone after maxillary protraction with different alternate rapid maxillary expansion and construction (Alt-RAMEC) protocols in patients with skeletal class III malocclusion as a result of maxillary retrusion. Material and Methods: The patients with skeletal class III malocclusions were consecutively divided into two groups. Group 1 consisted of 17 patients (11 boys and 6 girls, mean age 11.31 6 1.71 years) who had the Alt-RAMEC protocol for 5 weeks, and group 2 consisted of 17 patients (10 boys and 7 girls, mean age 11.64 6 1.24 years) who had the Alt-RAMEC procedure for 9 weeks. In this study, 4 angular and 13 linear measurements were performed to evaluate the skeletal and pharyngeal airway changes that occurred after maxillary protraction. Results: A significant increase in the maxillary growth, inhabitation of mandibular growth, and clockwise rotation of the mandible caused the improvement of the maxillo-mandibular relationship in both groups. Those changes caused a significant increase in the upper pharyngeal airway dimension (P , .01) and affected the vertical position of the hyoid bone in both groups (P , .05 and P , .01, respectively). However, changes that occurred in both groups were found to be similar for all airway variables (P . .05). Conclusion: Upper pharyngeal dimension and vertical position of the hyoid bone were affected by the maxillary protraction with different Alt-RAMEC protocols. There were no statistically significant differences between the groups. (Angle Orthod. 2017;87:519-525)
