Resorbable Collagen Barrier Impeding the Extrusion of Obturating Material in Primary Molars Undergoing Resorption - A Randomized Clinical Trial.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption.

Study Design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group 'A'- 47 canals with collagen barrier (Test group) and Group 'B'- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed.

Combined Effect of Enamel Deproteinization and Intermediate Bonding in the Retention of Pit and Fissure Sealants in Children: A Randomized Clinical Trial.

Objective: This manuscript shows if enamel deproteinization along with an intermediate layer of bonding enhances the retention of pit and fissure sealants..

Study Design: Two hundred six mandibular first permanent molars were allocated to Group I (n=103) and Group II (n=103).
