The Coronal Pulp Cavity Index an aid in age determination -A Cone Beam Computed Tomography Study

Background: The objective of the present study was to assess accuracy age estimation from TCI ofmandibular molars (except wisdom teeth) both sides using CBCT images known and sex, so thatwe can apply this method estimate in living individuals skeletal material unknown age.Methods: A cross sectional retrospective conducted on a total 100 subjectswho were referred department for varied diagnostic purposes gender. All CBCTimages with fully visible pulp cavity selected. Two measurements taken at two different levels.Height crown (CH) height coronal (CPCH). Then tooth – index (TCI)for each calculated as follows: = CPCH X / CH.Results: Comparison value between male female showed no significant difference thegender. Among four mandibular (lower left right1stand 2nd molars) 46 47 correlateswell age. has prediction an R 0.426. Inter observermeasurements moderate good agreement measures.Conclusions: teeth found be reliable notgender determination. used determination forensic it is non- invasiveand also makes possible reconstruct planes showing anatomical imagedstructures planes.
