Comparison of physical and mechanical properties of mineral trioxide aggregate and Biodentine.

Background: Mineral trioxide aggregate (MTA) fulfills many of the ideal properties of the root‑end filling material. However, its low cohesive property often makes it difficult to handle. Biodentine, new calcium‑silicate‑based cement has been developed to improve some MTA drawbacks such as its difficult handling property and long‑setting time. Aim: The objective of this study was to compare at different times the microleakage of roots filled with Biodentine and white MTA (WMTA)‑Angelus and to investigate their setting time, handling properties and compressive strength. Materials and Methods: Root canals of single‑rooted teeth were instrumented, filled with either Biodentine or WMTA‑Angelus (n = 15 each) with two positive and two negative control roots and stored at 37°C. Sealing was assessed at 4, 24 h, 1, 2, 4, 8, and 12 weeks by a fluid filtration method. The initial setting time, handling properties, and compressive strength of the test groups were investigated by a vicat needle, questionnaire of operational hand feel, and universal instron machine, respectively. Results: Significant differences in microleakage were found between two groups at 4‑h and 24 h (P < 0.05) and no difference at 1, 2, 4, 8, and 12 weeks. No significant difference was seen in the setting time of MTA‑Angelus and Biodentine, though latter was found to have better handling consistency. Compressive strength of Biodentine was significantly higher than MTA‑Angelus. Conclusions: The results suggest that the new calcium‑silicate‑based endodontic cement provides improvement in sealing ability as well as clinical manageability of dental filling materials.

Endodontic management of open apex using Biodentine as a novel apical matrix.

Aim: Endodontic management of open apex using Biodentine as an apical matrix. Summary: An immature tooth with pulpal necrosis and periapical pathology imposes a great difficulty to the endodontist. Endodontic treatment options for such teeth consist of conventional apexification procedure with and without apical barriers. Biodentine™ is new calcium silicate based cement that exhibits physical and chemical properties similar to those described for certain Portland cement derivatives. This article demonstrates the use of the newer material, Biodentine as an apical matrix barrier in root end apexification procedure. This case reports present apexification and successful healing with the use of Biodentine as an apical barrier matrix. Conclusion: Apexification in one step using an apical plug of Biodentine can be considered a predictable treatment and may be an alternative to mineral trioxide aggregate apexification.

Successful management of pulpo-periodontal lesion in maxillary lateral incisor with palatogingival groove using CBCT scan.

Palatogingival groove is a rare developmental anomaly involving the lingual surface of the maxillary incisor and resulting in severe endodontic and periodontal lesions. This case report describes a multidisciplinary approach for the combined management of the endodontic and periodontal problems for successful rehabilitation of the involved tooth. Cone-beam computed tomography (CBCT) helped in correct diagnosis of the lesion and hence enabled effective treatment.
