| Sumario: | Introduction: Adequate knowledge of the anatomic variation and
root canal morphology is paramount for long term endodontic
success. The presence of two canals in Mesiobuccal (MB) root is
commonly associated with maxillary molars in various populations.
Aim: To retrospectively evaluate the prevalence of a second
mesiobuccal canal (MB2) in maxillary first and second molars
in Delhi-National Capital Region (NCR) population using Cone
Beam Computed Tomography (CBCT) analysis.
Materials and Methods: This retrospective study evaluated the
records of complete maxillary CBCT scans of 204 maxillary first
and second molars from January 2016 till May 2019 from different
CBCT centres in Delhi-NCR region to determine the anatomy and
morphology in June 2019. The prevalence of second MB2 canals
was recorded and associated with age, gender and symmetry.
The z-test for proportions was used to assess the differences
among the subgroups.
Results: The number of roots in 204 teeth in both maxillary molars
were determined. The prevalence of 3-rooted configuration was
98.55% in maxillary first molars and 79.4% in maxillary 2nd molars.
Also, in maxillary 2nd molars, 7.4% were single rooted and 13.2%
had 2-rooted configuration. Three rooted configuration and
variable canal number was commonly reported in maxillary molars.
Prevalence of MB2 canal was 87.2% in maxillary 1st molars and
64.2% in maxillary 2nd molars. Also, the prevalence was 87.2%
bilaterally in maxillary first molars and 65.7% on the right and
53.9% on the left in maxillary second molars respectively. Type IV
canal configuration was most prevalent in 44.60% of maxillary
first molars and type 1 configuration (35.78%) for the maxillary
second molars.
Conclusion: Prevalence of MB2 canals in maxillary first and second
molars was found to be high in North Indian population and the
clinician should suspect its presence in all cases. Prevalence of
MB2 had bilaterally symmetrical distribution without any association
with age or gender. The MB roots were more likely to exhibit type IV
and type II canal configurations in maxillary first molars and type I
and type II configurations in second molars. |
