Abstract
Introduction: Maxillary canine usually has a single root, but variations have been seen because of
several events occurring during the tooth development. The variation in root morphology can be seen
due to ethnicity and genetic differences. Few studies studies on morphology and root dimension of
permanent maxillary canine using Cone Beam Computed Tomography (CBCT) Technique have been
conducted in Pakistan. Hence the objective of the study was to assess the morphology and root
dimension of permanent maxillary canine in Peshawar, Pakistan using CBCT Technique.
Material and Methods: A total of forty-three (43) radiographic (CBCT) archives of maxillary canine
from November 2017 to February 2018 were studied and assessed. The CBCT along with history file was
assessed to ensure that the CBCT of permanent maxillary canine included were of patients aged 15 and
above. Each permanent canine was examined, and tooth length was measured. The mesio-distal width
and bucco-palatal width at Cemento-Enamel Junction (CEJ) and deflection of tooth and root was
observed using CBCT. The root canal pattern was assessed and classified according to Vertucci’s
classification. The data were analyzed in SPSS software (SPSS version 17) using the Chi-squared test and
the t-test.
Results: All teeth examined under CBCT were having one root and Type I (100%) canal configuration.
Maxillary canine revealed a predominantly straight root (65.1%). The anatomical length of maxillary
canine and root was 22.7 mm and 15.49 mm while average mesio-distal and bucco-palatal width of the
root at Cemento-Enamel Junction (CEJ) was 5.77mm and 6.70mm. 65.1% of the maxillary canines were
having no deflection
Conclusions: The most frequent canal pattern reported in the maxillary canine was Type I (100%). The
length of maxillary canine in Asian population ranges between 22.7mm – 26.4mm. The maxillary canines
are bulkier on MD and BP aspect in Mardan then Peshawar.
