Volumetric pulp chambers measurements in mandibular and maxillary permanent first molar using cone-beam computed tomography by age and gender

Abstract

Aim: The aim of this study was to demonstrate the anatomical structureof pulp chamber, measure the volume of the total pulp chambers in mm3and evaluate the pulp chamber volume changes by age and genderstatistically in mandibular and maxillary first molars by means of CBCT.Methodology: In our study, CBCT examinations of patients between theages of 7-18 years, which were carried out due to different reasons wereevaluated retrospectively. The CBCT images of healthy total of 160 lowerand upper right permanent first molar teeth were selected randomly andthe volumes of the total pulp chamber were measured in mm3 with the 3DSlicer software program. We analyzed the collected data with statisticalanalysis methods and we evaluated whether there was any differencebetween the patients grouped according to the age in respect of volumechanges in the total pulp chamber and whether there was any differencebetween the mean volume values and gender of the patients within thesame group.Results: Comparison of the volume measurements of the lower and upperfirst permanent molar teeth between the groups showed that the volumevalues of the total pulp chamber decreased depending on the age (p
