Objective:The present study aimed to compare dentoskeletal changes in mandibular-deficient patients treated with Bionator and Farmand appliances.Methods:This study included 54 subjects treated for class II division I malocclusion. All subjects fulfilled the following criteria: ANB>5°, SNB5 mm. The Bionator group consisted of 27 patients (15 girls, 12 boys) with the mean age of 11 (SD 1) years and the Farmand group consisted of 27 patients (17 girls, 10 boys) with the mean age of 11.1 (SD 1.4) years. Statistical analyses were performed using t-test, paired t-test, Wilcoxon, and Mann–Whitney test.Results:In the Farmand group, SNB significantly increased from 74.3° (SD 1.7) to 77.6° (SD 2.3) and ANB decreased by 3.2° (SD 1.7) (p

Abstract Background The aim of this study was to investigate the prevalence of cleft sidedness, and the number of congenitally missing teeth in regard to cleft type and gender. Methods The charts, models, radiographs, and intraoral photographs of 201 cleft patients including 131 males with the mean age of 12.3 ± 4 years and 70 females with the mean age of 12.6 ± 3.9 years were used for the study. T test, Chi-square, and binomial tests were used for assessment of the data. Results and conclusions One hundred forty-eight of the subjects suffered from cleft lip and palate followed by 41 subjects who suffered from cleft lip and alveolus. Chi-square test did not show any significant difference between the genders. Binomial test showed that left-sided cleft was more predominant in unilateral cleft lip and palate patients (P

Background and Aim: The aim of the present study was to evaluate the cephalometric changes in Class II division 1 mandibular deficient patients treated with Farmand functional appliance. Methods and Materials: Twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. All the subjects were treated with Farmand functional appliance. Paired t-test and Wilcoxon test were used to evaluate the data. The significance level was set at P

Introduction Failure in the fusion of medial nasal processes and maxillary prominences would result in the development of a cleft lip while failure in merging the palatal shelves would result in the development of a cleft palate (CP). At present, patients with a cleft palate (CP) have often undergone corrective surgery before 1 year of age. However, an oronasal fistula (ONF) often remains in the palate after surgery. Methodology In this historical cohort, 40 patients with CP, 6-10 years old, who had undergone corrective surgery at 1 year of age were selected by targeted sampling and assigned to two groups with ONF (N=20) and without ONF (n=20). The two groups were matched in terms of age and gender. All patients had an intraoral photograph of the maxilla and a lateral cephalogram. Twenty-three cephalometric parameters were measured prior to the orthodontic treatment and compared between the two groups using a t-test. Results CP patients with ONF had significantly higher Y-axis, gonial angle, Go1, Go2, GoGn-SN, U1-SN, and lower lip to E line compared with those without ONF (P<0.05). The Jarabak index was significantly lower in the CP patients with ONF compared with those without it (P<0.05). The difference in other cephalometric parameters was not significant between the two groups (P>0.05). Conclusion Patients with ONF had significantly greater growth in the vertical dimension compared with those without ONF. Yet, the difference in the anteroposterior dimension was not significant between the two groups. [ABSTRACT FROM AUTHOR]
