Purpose
The aim of this study was to determine the
differences between the positional relationship of the crown contour and the
pulp chamber of left and right maxillary first molars, as well as their
morphological characteristics by using micro-CT system with reconstruction from
a volumetric rendering software.
Materials and methods
In total, 21 extracted maxillary first
molars, including 11 left and 10 right teeth, were used. The positional
relationship between the crown contour, pulp chamber and morphology of the
teeth were investigated three-dimensionally by means of micro-CT imaging.
Results
Closest distance of mesio-buccal pulp horn
to enamel surface in mm was calculated as 2.5±0.20 mm for right and 2.29±0.17
mm for left teeth. This difference was statistically significant (p=0.017). The
means of closest distance of disto-buccal pulp horn to enamel surface were also
significantly different between left and right teeth (p=0.001). The mean pulp
volumes of right side and left side teeth were, respectively, 32.94±3.19 mm3
and 33.71±2.82 mm3 but this difference was not statistically significant.
Conclusion
These results suggest that right and left
maxillary first molars should be treated differently during preparation of
cavities. Further studies must be done with larger samples as well as for other
molar teeth in different populations to reveal the morphology of the molar for
further considerations in restorative dentistry.
