ABSTRACT
Background: Age Calculation Has Become Increasingly Important In Forensic Sciences. It Considered As The Ideal And Most Accurate Method To Evaluate The Pulp/tooth Volume Ratio. Cone-Beam Computed Tomography (CBCT) Can Be Used To Measure The Rate Of Secondary Dentine Deposition Which Is Depicted By Reduction In The Pulp Area Objective: The Aim Of The Study Was To Investigate An Age Estimation Method Based On The Ratio Of The Pulp/tooth Volume For Egyptians.

Materials and Methods: A Random Selection Of 150 Sets Of 3D Cone Beam CT Tooth Images Of Mandibular Canines Were Collected. DICOM FILES Were Used For Tooth And Pulp Segmentation To Form A 3D Model To Calculate Volume Of Both Pulp And Tooth. Linear Regression Analyses Is Then Performed To Establish A Correlation Between The Chronological Age And The Pulp/tooth Volume Ratio.

Results: Pulp/Tooth Volumes (PTV) Showed No Statistically Significant Difference Between Males And Females. PTV Values Yielding The Linear Regression Formula:� Age = 80.755- 805.599 (PTV).

Conclusions: Using Cone-beam CT 3D Images; The Ratio Of Pulp/tooth Volume Can Be Calculated. For Age Estimation Based On This Ratio. Keywords: Dental Age, Forensic Odontology, CBCT, Canine, Tooth Volume
