Evaluation of Radiological Outcomes of Theracal Light Cured (TLC) And Calcium Hydroxide As Indirect Pulp Capping Agents In The Treatment Of Deep Carious Lesion Of Permanent Molar Teeth.

To evaluate the radiographic changes in permanent molar teeth submitted to indirect pulp treatment (IPT) over 12 months period. This prospective comparative study was performed in Department of Conservative Dentistry and Endodontics, Faculty of Dentistry, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from August 2016 to July 2017. Fifty permanent molar teeth with deep caries, but without preoperative signs and symptoms of irreversible pulpitis, received for indirect pulp capping. The teeth were randomly divided into two groups, according to the material used for protection of the dentin- pulp complex: Group A - Twenty five teeth were treated by using Ca(OH)₂ Control and Group B - Twenty five teeth were treated by using theracal light cured (TLC) experimental. Both groups were restored with composite restoration. All patient were evaluated radiographically at 3.6 and 12 months interval to assess formation of reparative dentin. The success of IPT was after 12 months observation period, 24 cases (96%) of TLC and 17(68%) Ca(OH)₂ treated teeth showed reparative dentin formation. A statistically significant was obtained in all observation periods where TLC showed more capable for reparative dentin formation than that of Ca(OH)₂. It can be concluded that radiographically TLC is more effective than that of Ca(OH)₂ as indirect pulp capping agent.
