Description
Summary:Introduction: Clinical information regarding skeletal and dental characteristics are essential for orthodontic diagnosis and treatment planning. Therefore, an evaluation to predict the association between skeletal and dental variables would prove diagnostically invaluable. Material and methods: Orthodontic study models and lateral cephalograms of 117 Malay patients between 18 and 41 years old (mean age 26.5 ± 5.38) were evaluated for molar relationship (Class I, II or III), A point-Nasion-B point (ANB) angle (skeletal Class I, II or III) and maxillary-mandibular planes (MMP) angle (normo-, hypo- or hyperdivergent). Reassessment was done after two weeks for intra- and inter-examiner reliability. The association between these variables were analysed with Chi-square test. Results: There was perfect agreement for intra- and inter-examiner reliability with kappa scored 1. A highly statistically significant association between molar relationship and sagittal skeletal pattern (p=0.000), and statistically significant association between sagittal and vertical skeletal pattern (p=0.048) was found. There was no significant association between molar relationship and vertical skeletal pattern (p=0.855). Conclusion: Skeletal Class I, molar Class II and normodivergent vertical pattern were the most prevalent. There was association between sagittal and vertical dimension, and between sagittal and molar relationships. However, there was no association between vertical plane and molar relationships.
