DESIGN: Retrospective study.
SETTING: School of Dental Science, Universiti Sains Malaysia.
SUBJECTS: Eighty-four Bangladeshi children with nonsyndromic UCLP who received cheiloplasty and palatoplasty.
MAIN OUTCOME MEASURES: Dental models were taken at 5 to 12 years of age (man: 7.69), and dental arch relationships were assessed using modified Huddart/Bodenham index (mHB) by two raters. Kappa statistics was used to evaluate the intra- and interexaminer agreements, chi-square was used to assess the associations, and logistic regression analysis was used to explore the responsible factors that affect DAR.
RESULTS: The total mHB score (mean [SD]) was -8.261 (7.115). Intra- and interagreement was very good. Using crude and stepwise backward regression analysis, significant association was found between positive history of class III (P = .025, P = .030, respectively) and unfavorable DAR. Complete UCLP (P = .003) was also significantly correlated with unfavorable DAR.
CONCLUSION: This multivariate study suggested complete type of UCLP and positive history of class III had a significantly unfavorable effect on the DAR.
STUDY DESIGN: Observational, cross-sectional study.
PLACE AND DURATION OF STUDY: Orthodontic Department of Baqai Medical University, Karachi, Pakistan, from August to October 2013.
METHODOLOGY: Atotal of 209 pre-treatment lateral cephalometric radiographs of orthodontic patients were selected from departmental records, comprised of 92 males and 117 females. Radiographs were traced for measurements of ANB, Wits appraisal, Beta-angle, W-angle and Yen-angle. Patients were categorized into skeletal classes I, II, and III on the basis of performed measurements, incisor classification, and profile recorded from their records. Descriptive analysis was used to obtain median interquartile range in both the genders and Mann-Whitney U-test was used to observe gender dimorphism.
RESULTS: Skeletal class II was the most prevalent type of malocclusion. There were no difference in the obtained measurements between males and females except the Wits appraisal and Beta-angle in class II patients, which showed significant difference in values (p < 0.05).
CONCLUSION: Pakistani population has no significant different difference in the craniofacial morphology of males and females, with the exception of Wits-appraisal and Beta-angle in class II cases.
