Dental Arch Crowding in Permanent Dentition Among Class I And Class Ii Div 1 Malocclusion

Crowding of dental arches is a common malocclusion and it involves improper alignment of the anterior or posterior teeth. The primary objective of the study was to evaluate the severity of crowding in subjects with Class I and Class II malocclusions. This retrospective study was performed using case records of subjects visiting a private dental college. The present study included 200 subjects with equal distribution of class I and class II malocclusions. Data on type of malocclusion and other associated factors was recorded and tabulated. Analysis of the data was performed using SPSS, descriptive statistics and Chi square tests were done. The study reported 53% mild crowding, 31% severe crowding and 16% moderate crowding in class 1 malocclusion whereas in Class II division 1 malocclusion 50% severe crowding, 46% mild crowding, 4% moderate crowding was observed. Within the limits of the present study, it can be concluded mild crowding was more prevalent followed by severe and moderate crowding in class I malocclusion whereas in Class II division 1 malocclusion severe crowding was more common followed by mild and moderate crowding. No significant association between the type of malocclusion and the severity of crowding was noted.
