Tomographic Evaluation of Pulpotomy in Young Permanent Teeth Using Human-treated Dentin Matrix

The study was conducted as a split-mouth randomized clinical trial, approved by research ethics committee, Faculty of Dentistry, Tanta University, and carried out at Pediatric Dentistry Department, Faculty of Dentistry, Tanta University. The material preparation was conducted at Pharmaceutical Technology Department, Faculty of Pharmacy, Tanta University. 20 children of both sexes aged from 6 to 8 years old were selected with bilateral deeply carious young permanent mandibular first molars that are indicated for pulpotomy procedure.The selected deeply carious molars were randomly divided into two groups as follows:

Group I (Study group): 20 molars were treated with hTDM. Group II:

(Control group): 20 molars were treated with White MTA. The participating cases were evaluated clinically 3, 6, 12 and 18 months. Digital periapical radiographs was taken at 6 month follow-up period to ensure the state of the treated teeth or if there was necessary condition.

Tomographic evaluation was performed immediate postoperatively and at 18 months.
