Volumetric pulp chambers measurements in mandibular and maxillary permanent first molar using cone-beam computed tomography by age and gender
Aim: The aim of this study was to demonstrate the anatomical structure of pulp chamber, measure the volume of the total pulp chambers in mm3 and evaluate the pulp chamber volume changes by age and gender statistically in mandibular and maxillary first molars by means of CBCT.
Methodology: In our study, CBCT examinations of patients between the ages of 7-18 years, which were carried out due to different reasons were evaluated retrospectively. The CBCT images of healthy total of 160 lower and upper right permanent first molar teeth were selected randomly and the volumes of the total pulp chamber were measured in mm3 with the 3D Slicer software program. We analyzed the collected data with statistical analysis methods and we evaluated whether there was any difference between the patients grouped according to the age in respect of volume changes in the total pulp chamber and whether there was any difference between the mean volume values and gender of the patients within the same group.
Results: Comparison of the volume measurements of the lower and upper first permanent molar teeth between the groups showed that the volume values of the total pulp chamber decreased depending on the age (p<0.05). Regarding gender, volume decrease related to age was statistically more significant among females. We determined in all age groups except age 7-9 group that the volume value of the total pulp chamber of the upper permanent first molar teeth was statistically higher than the volume value of the total pulp chamber of the lower permanent first molar teeth (p<0,05).
Conclusion: We believe that CBCT is an easy and conservative method for the 3D-imaging of the pulp chamber, volume measurement and examination of the dimensional changes of the total pulp chamber depending on deposition of secondary dentin.
