Bio-C Repair - A New Bioceramic Material for Root Perforation Management: Two Case Reports

Abstract

These case reports aimed to describe the management of lateral perforation in the middle cervical third of the root in two maxillary incisors with pulp canal calcification using Bio-C Repair, with safe and viable clinical treatment strategies. Digital radiographic exams were obtained with different angles and analyzed using different filters. Cone-beam computed tomography (CBCT) images were requested to show the actual position of the canal, location of the perforation, and guide the strategic planning of the case. Subsequently, cavity access was prepared with the aid of dental operating microscopy. After perforation was identified, granulation tissue was removed and the original canal was identified and then dressed with calcium hydroxide. In the second visit, the perforation was filled with Bio-C Repair and the canal system filled with gutta-percha points and a root canal sealer (Bio-C Sealer). The teeth were restored with glass fiber post, 4 mm beyond the perforation level, and provisory crowns. Both teeth treated as described above were functional and asymptomatic with a 1-year clinical and radiographic assessment. The Bio-C Repair is suggested as a new cement option for the management of lateral canal perforations, with effective results as observed after a one-year follow-up.

Physicochemical properties, cytotoxicity and bioactivity of a ready-to-use bioceramic repair material

“…Bio-C Repair is a pre-mixed cement 5 , and the setting reaction occurs with moisture from the dentin and adjacent tissues 6 . Bio-C Repair has cytocompatibility similar to that of tricalcium silicate-based materials 7 , induces biomineralization, and shows appropriate clinical results 8 . However, there are no studies evaluating the physicochemical properties of this material.…”

The improvement of the art of saving teeth by endodontic microsurgery - case report

“…The root end filling material MTA (Angelus, Brazil) was placed into the root end preparation. This material has been the first choice for over two decades (Toubes et al, 2021;Souza et al, 2021) as long as its wide acceptance as a root end filling material is due to its excellent properties of biocompatibility, sealing (Osborne et al, 2005;Shinbori et al, 2015) and potential bioactive actions such as biomineralization. (Chong & Rhodes, 2014).…”

A Review of the research methods and progress of biocompatibility evaluation of root canal sealers

“…The tested sealers all showed good biocompatibility [75][76][77]. Kênia et al published a case report on root canal puncture repair [78], after 1-year follow-up observation, the treated teeth had no obvious clinical symptoms. The healing of the periapical tissue will be affected by the body's conditions, and the postoperative pain was affected by various factors, such as the estimation of working length with an apex locator connected to every file [79], number of visits [80], choice of instrumentation [81], it was difficult to consider the potential impact of each factor on pain aggravation or reduction.…”
