Objective: The aim of this study was to investigate the correlation of the skeletal malocclusion with dental malocclusion in the sagittal plane, which includes molar relation in orthodontic patients.
Material and Methods: The cephalograms and casts of 100 of vertically normal patients were included in this retrospective cross-sectional study. ANB and Wits were calculated for skeletal classification and angle classification for dental malocclusion classification. All statistical analyses were performed using SPSS 16 software (SPSS Inc., Chicago, Ill, USA). Descriptive statistics were performed for the calculation of the mean, standard deviation, minimum, maximum, and range. The Spearman’s correlation coeficient (r) was also calculated between the measurement skeletal and dental relationship in sagittal relationship in female and males. Statistical significance was predetermined at the 95% level at (P < 0.05).
Results: Of total 100 patients 58(58%) were females and 48(48%) were males. The mean age was 21±3.6 years. The mean value for ANB angle in this sample was 2.5, 4.7 and -1.5 for skeletal class I,II, and III respectively. Class I malocclusion showed the highest variation in ANB; the standard deviation was largest.. There was a definite and statistical significant correlation between ANB and Wits value. The highest correlation was for skeletal class III patients. The correlation between dental (angle classes of molar) and skeletal ANB and Wits was weak and statistically nonsignificant. Only skeletal class II carried a positive correlation.
Conclusions: There is a weak correlation between skeletal and dental malocclusion.
