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 at 12 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

Monoblock obturation technique for non-vital immature permanent maxillary incisors using mineral trioxide aggregate: results from case series

Ten patients presented with non-vital immature teeth for root canal treatment. In all these cases the pre-operative clinical examination revealed apical periodontitis with a buccal sinus tract of endodontic origin. These cases were treated by a mineral trioxide aggregate [MTA] monoblock obturation technique. Follow-up evaluations were performed at 1 - 2 years after treatment. Eight out of 10 cases were associated with periradicular healing at follow-up evaluation. Mineral trioxide aggregate Monoblock obturation technique appears to be a valid material to obtain periradicular healing in teeth with open apices and necrotic pulps
