Three-dimensional Observation of Decrease in Pulp Cavity Volume Using Micro-CT: Age-related Change

Year: 2010

Type: article

Abstract: We investigated three-dimensional decrease in the volume of the pulp chamber caused by age-related secondary dentin formation using micro-CT and evaluated the applicability of the results to evaluation of age taking into account sex, age and tooth type.Decrease was slightly higher in females than in males, and a higher correlation between decrease and aging was observed in females.A comparison between age-groups revealed that decrease progressed between the fifties and sixties in males, and the forties and fifties in females.A stronger correlation between aging and decrease was observed in the mandibular central incisors than in the mandibular second premolars.This correlation was higher than other correlations between sexes and age-groups. Key words: Pulp chamber-Secondary dentin-Micro-CT -Age estimation-Three-dimensional measurement size and area of a tooth and pulp cavity are measured on ground sections or radiographs and a regression analysis is performed to determine correlations between the ratios of these values and age.These results are then used to estimate age 3,4,7,10,15) .However, these ground section or radiograph-based methods Bull Tokyo Dent Coll (2010) 51(1): 1-6
