“…In fact, in a previous pilot study our research group found that if a -8°reverse-taper preparation were digitally blocked-out at the CAD stage, approximately 28 mm 3 of dental structure could be preserved in the mesiodistal aspect (relative to a 22°preparation, Fig 1). To put the relevance of this seemingly small amount of volume into perspective, one should keep in mind that the average pulpal volume of an adult maxillary central incisor 43 is approximately 21 mm 3 . Therefore, preserving such amount of tooth structure is definitely not negligible.…”

“…With the increase of the use of 3-dimensional imaging methods in dentistry, a number of studies that used CBCT to make the measurements related to pulpal chamber anatomy have been published. In these studies, it was proposed that CBCT is a more useful tool to determine pulpal chamber parameters and it enables precise and correct measurement of age-related volume changes in dental tissues (9,14,16,23).…”

In our study, pulpal chamber was segmented and volume measurements were made with 3D Slicer software, which was tested by Harvard Surgery Planning Laboratory and used in several studies in health sciences (34)(35)(36)(37)(38)(39)(40)(41)(42)(43).…”

“…Pulpal chamber size can be evaluated in detail by using axial, sagittal and coronal CBCT sections (14). Volumetric changes of pulpal chamber with age can be measured precisely and correctly by segmenting and reforming CBCT images (15,16). This study was aimed to show in 3dimension the anatomy of pulpal chamber of permanent first molar teeth in maxilla and mandible, to compare total pulpal chamber volume according to age and gender, and to evaluate pulpal chamber volume change with secondary dentin accumulation.…”

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.

“…Usually, evidence related to the regressive phenomena due to secondary dentin deposition are treated using different kinds of regression model that consider age as the predictor variable and the volume or area of the pulp cavity as the dependent variable [5,[11][12][13]15,16,[18][19][20][21][22][23][24][25][26][27][28][29]. However, previous studies highlighted that such a statistical methodology presents some disadvantages, both statistical [30][31][32] and conceptual [33,34], when used in age estimation for forensic purposes.…”
