Clinical Outcome of Mta Apical Plug and Mta Monoblock Technique for Apexification of Non-vital Immature Permanent Incisors. in Vivo Study

OBJECTIVE: To compare the clinical outcome between mineral trioxide aggregate apical plug and mineral trioxide monoblock technique of endodontic apexification procedure of non vital permanent incisors with open apexes. STUDY DESIGN: Clinical in vivo Cross sectional comparative study PLACE AND DURATION: Endodontic department/College of Dentistry Ziauddin University, Karachi. Study duration was from January 2010 to January 2013. METHODOLOGY: Total fifty patients of male or female visited Endodontic department with non vital permanent maxillary incisors with open apexes were selected. The selected teeth were divided into 2 groups by simple random method. Group A was treated with MTA apical plugtechnique and the group B was treated with MTA monoblock technique. The assessment of clinical outcome was carried out at12 and 24 month follow-up appointments. The presence of signs and symptoms with treated cases were considered as clinical failure, while treated cases without symptoms were considered as clinical successful cases. The treated cases were also checked radiographically according to the published criteria of evaluation and categorized as successful, uncertain outcome and failure cases. The recorded data were analyzed by using the statistical software. RESULTS: The results of the study showed clinical success in both group and radiographic success was found to be 68% and 76% in MTA apical plug group and 84% and 92 % in MTA monoblock group at 12 and 24 months intervals. CONCLUSION: This study have showed no significant difference in clinical outcome of MTA apical plug and mineral trioxide monoblock technique for endodontic apexification procedure of non vital permanent incisors with open apexes.
