Brief Summary

the object of this study is to evaluate clinically and radiographically the effect of using Biodentine and Mineral Trioxide Aggregate as coronal plug materials in revascularization of non-vital immature teeth

Detailed Description

Traumatic injury to the anterior teeth is commonly found among young children, represent one third in boys and one fourth in girls. Because the root development completed two years after eruption of the tooth into the oral cavity, an incomplete root development is one of the most common complication seen in traumatized teeth. Loss of pulp vitality before dentine deposition is completed, leaves a weak root more susceptible to fracture as a result of the thin dentinal walls. It will also lead to a poor crown/root ratio, with possible periodontal injury as a result of increased mobility.

Several techniques have been advocated to manage the open apex of immature teeth, including calcium hydroxide (Ca(OH)2) apexification or apical barrier technique with Mineral Trioxide Aggregate (MTA). Although these techniques were successful in obtaining apical closure and healing of the apical pathosis, they have certain disadvantages, as the root walls of the immature tooth remain thin and short as hard tissue barrier formation only occurs apically, with no further root development.

As an replacement to traditional methods, the use of a regenerative endodontic procedure has been recommended as it may strengthen the root walls through the deposition of hard tissue and promote the development of a normal apical morphology. MTA was chosen to be placed over blood clot to provide excellent seal and it was considered the recommended material for regenerative procedures.The application of MTA over a blood clot was technically difficult, and condensation resulted in displacement of the material apically. Another important note was the prolonged setting time of MTA which resulted in postponing placement of composite restoration to next appointments and post-treatment tooth discoloration.

Biodentine has the same mechanical properties as human dentine, very low cytotoxicity and overcome clinical drawbacks of white MTA. It had better consistency and allow its condensation without any apical displacement. Biodentine sets within twelve minutes, which allow placement of composite restoration in the same appointment. Biodentine is tooth-colored and doesn't cause the discoloration resulted from the presence of the material at level of the orifice.

Study Groups

Biodentine

3-4 mm of Biodentine (Septodont, St. Maur-des-Fosses, France) was applied over the clot carefully in group I by using amalgam carrier. material was packed lightly with a moistened cotton pellet and Periapical radiograph was taken to confirm coronal seal in the second visit of dental pulp revascularization.

Group Type: EXPERIMENTAL

Biodentine

Intervention Type: DRUG

a procedure used to regenerate a pulp-dentine complex that restores functional properties of this tissue, fosters continued root development for immature teeth, and prevents or resolves apical periodontitis.

Mineral Trioxide Aggregate

3-4 mm of white Mineral Trioxide Aggregate (Angelus, Londrina, Brazil) was applied over the clot in group II by using amalgam carrier. material was packed lightly with a moistened cotton pellet and Periapical radiograph was taken to confirm coronal seal in the second visit of dental pulp revascularization.

Group Type: ACTIVE_COMPARATOR

Mineral Trioxide Aggregate

Intervention Type: DRUG

a procedure used to regenerate a pulp-dentine complex that restores functional properties of this tissue, fosters continued root development for immature teeth, and prevents or resolves apical periodontitis.
