Regenerative Endodontic Therapy by Using MTA, Biodentine, and Calcium Hydroxide
Objectives: According to American Association of endodontists statements, 2016; three goals of regenerative endodontic therapy (RET) in immature non-vital teeth are: the elimination of symptoms and the evidence of bony healing, increased root wall thickness and/or increased root length and positive response to vitality testing. In recent years, clinical treatment protocol by using different biomaterials for different terms of RET, guided endodontic repair and pulp revitalization were published. This case series report was to compare the RET outcome in immature permanent teeth with necrotic pulp using MTA, biodentine and calcium hydroxide.
Methods: Five immature mandibular premolars with open apex and evidence of periapical radiolucency/ sinus tract cases (age range from 10 to 12, 1 male and 3 female) were included. After local anesthesia and proper isolation using rubber dam, which RET protocol (AAE, 2016) was done for individual case using MTA, biodentine and Calcium hydroxide. Patient was recalled after 4 months to 1 and half year. The treated teeth were evaluated clinically for vitality and radiographically for any evidence of root canal thickness or formation.
Results: Clinically, treated infected canals combined with sinus tract cases revealed totally subsided after 1 or 2 weeks' Ca(OH)2 dressing and immediate biomaterial dressing in all teeth. Biodentine cases responded positively to cold test and electric pulp testing after 1 month. Postoperative radiographs showed good bone healing in all teeth. Calcium hydroxide case got apical closure. MTA cases showed that thickness of root canal wall improved.
Conclusions: All the three materials tested have the ability to serve as regenerative endodontic reparative agents to induce root canal wall thickness and root formation. Further long-term evaluation should be continued.
