Abstract

From earlier studies, it is known that dentitions featuring PDC (palatally displaced canine) showed various anomalies such as peg shaped and missing laterals incisors, other missing teeth and spaced dentitions. These anomalies which have associated genetic origin have similar association with PDC. In dentitions featuring PDC, reduction in tooth size, particularly lateral incisors was recorded.  A recent Study was done in Israel to investigate the connection between palatal canine displacement and tooth size reduction in other teeth in maxilla. The present study was done to put this study into Indian context within Mysore population. The records of patients attending Farooqia Dental College were collected. The diagnosis was made on basis of clinical examination and standardized radiographs. Bilateral and Unilateral Subjects were analysed using study model casts for measuring the M-D and B-L dimensions of the maxillary dentition using a Digital Vernier Calliper.
The mean B-L width of all maxillary teeth in PDC subjects were significantly smaller by approximately 0.5 mm than in the control group. The B-L width of Lateral incisors was found to be significantly smaller for PDC subjects which was statistically significant. There was a distinct trend towards narrower teeth in the PDC group which was statistically significant for the maxillary first premolar and first molar.
Based on the results of the study it can be safely assumed that the results can be applied to Indian context. The tooth size variation information can be used as an additional diagnostic tool in clinical settings to determine the position of the canine in canine displacement cases.
