Evaluation of Upper Canine Eruptive Course: A Radiographic study

Abstract

Early detection of upper canine eruptive problems, give a better chance for the
preventive steps to be taken. 328 maxillary canines in pre-emergence phase, were
studied on the bases of (164) panoramic radiographic records of Iraqi children age 5-
12 years (72 boys - 92 girls). Canine inclination (CI) (relative to a plane between the
suborbital points), and its relation to the lateral incisor (CLR) were studied. The
lateral incisor developmental stage (LID) was evaluated too.
Results showed that, in initial stages of (LID), the canine lateral incisor relation
(CLR) is almost characterized by overlapping, a situation rarely seen in the final
stages. Only 8-15% of the overlapping is found when the lateral incisor was
completely developed (CO), detecting possible canine anomalies in this stage,
especially when associated with other clinical signs as non-palpation of the cuspid
bulge in the alveolar process. Then extraction of the primary canine is advised to
prevent impaction.
