Abstract
Objective: To evaluate the secondary dentin formation with age. Methods: We evaluated 36 bitewing radiographs of the first maxillary and mandibular molar, aged 15 to 25 years. The images were grouped into three groups. Pulp area of clinical crown, total pulp area and pulp width at cervix measurements were made from image of each first molar. Results: Pulp area of clinical crown, total pulp area and pulp width at cervix significantly decrease with advanced age. Conclusion: Secondary dentin acts as indicator of age because area decrease is due to secondary dentin formation.
