- Title
Estimation of remaining dentine thickness under deep carious lesions in deciduous molars.

- Abstract
Introduction: The treatment of deep carious lesions approaching healthy pulp has always been a challenge. A shallow-looking cavity may be in fact much deeper and result in pulp exposures during cavity preparation and caries removal. If it were possible to accurately measure the depth of the remaining dentine thickness and, therefore, the proximity of the pulp to the base of a lesion, excavation could be terminated before exposing the pulp. Objective: The aim of this study is to estimate the remaining dentine thickness below deep carious lesions in deciduous molars. Methodology: In vivo periapical radiographs will be taken for each tooth. The remaining dentine thickness will be measured using Vernier caliper. Cone-beam computed tomography systems (CBCT) will be done for the particular tooth. The remaining dentine thickness will be measured again in CBCT and the reading will be compared with that of the intraoral periapical. Now, the caries will be excavated by hand intraorally, and the number of cases going for restoration or pulp therapy would be noted. Hence, the remaining dentine thickness would be obtained beyond which pulp therapy would be required. Conclusion: It is not possible to accurately determine the dimension of the remaining dentine thickness from a periapical radiograph alone. The addition of CBCT to the study helps in estimating the amount of remaining dentine thickness under deep carious lesions with more accuracy beyond which pulp therapy would be required.
