Objectives: Frequency of typical and non-typical root and canal
morphology of primary teeth, which in clinical practice cannot
be detected using 2D radiographic images,
should be known by clinicians to decrease failures arising
from complexity of root canal morphologies. The
aim of this in vitro study was to evaluate morphologic variations in mandibular
primary molars’ root canal systems.
Materials and
Methods: Primary mandibular 1st
(n=17) and 2nd (n=33) molars were scanned using micro-CT. 3D root
models were obtained and root canal morphologies were evaluated according to a
modified Vertucci classification. Type 1 and Type
4 canal morphologies were evaluated as ‘normal’ and all other types and
‘non-typical’ canal morphology were evaluated as ‘abnormal’ root canal
morphology.
Results: Most common root canal morphology among mandibular
primary 1st molars were Vertucci Type 4 morphology for both mesial
and distal roots (47% and 41.2% respectively), and non-typical morphology for
both the mesial and distal roots (45.7% and 21.2% respectively) of mandibular
primary 2nd molars.
Conclusions: Wide range of morphologic variations and frequency of
non-typical morphology could be seen especially among mandibular primary 2nd
molars and use of disinfectant irrigants and root canal
fillings with high antibacterial efficacies are important in order to decrease
failures arising from these inaccessible areas.
