The association between facial and dental asymmetry in the adolescents with class II subdivision

Research output: Contribution to conferenceAbstractpeer-review

Abstract

The objective was to assess the differences in the facial parameters of the individuals with Class II subdivision (Class IIs) compared with Class I and Class II individuals. The sample was retrieved from an ongoing growth study at the Rīga Stradiņš University. From the initial sample of the 107 individuals with facial scans, 17 individuals were excluded from the occlusion analysis for different reasons. Total sample was 90 individuals (47 males and 43 females) with an average age of 15 years. In the final sample was 30 Class I, 21 Class II and 30 individuals with Class IIs. The facial scans were obtained using 3dMD facial scanner. The occlusion was scanned with 3Shape scanner. The dental midline was significantly deviated to the Class IIs side compared with Class I (p=0.030) and Class II (p<0.000) individuals. The deviations of the upper midline points (mid-endocanthion, mid-exocanthion, mid-nasion and mid-glabella) from the midsagittal plane were more significant than those of the lower parts of the face, except for the mid-pogonion and mid-chelion. The mid-pogonion point in the Class I individuals was perfectly set on the midsagittal plane (0.01 ± 1.58). It was shifted to the respective side in the Class IIs individuals (0.45 ± 1.51) and to the right in the Class II individuals (-0.47 ± 1.23). Class IIs individuals have the respective side chelion higher. The mid-chelion point was shifted to the left in the Class IIs. Occlusal parameters are represented in the face to some extent. The facial asymmetry seems to be beyond the occlusion in Class I and Class II individuals.
