Applicability of Pulp Tooth Area Ratio in Age Estimation using Mandibular Premolars

Introduction: Age estimation is an important parameter in forensic for identification of individuals. Cameriere developed pulp tooth area ratio as age method Orthopantomogram. Objective this study was to use Pulp mandibular premolars and derive population-specific equations estimation. Materials Method: A retrospective conducted Department Oral Maxillofacial Pathology, Kantipur Dental College Teaching Hospital from June 2021 November after ethical clearance no 10/021. Total 392, Orthopantomograms patients aged 17- 50 years with were retrieved Medicine Radiology. The radiographic images saved JPEG file processed using Image J software. measured their calculated. Result: There 178 males 214 females mean 22.39 years. Paired T tests showed good intra observer agreement between premolars.
