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. - See more at:
