Dental autotransplantation with i-PRF and apical sealing with Biodentine: a clinical case report with unfavorable evolution

Mon, 06 Apr 2026 17:42:48 +0000

Introduction: dental autotransplantation is a conservative therapeutic alternative indicated when implants are contraindicated. Objective: The objective of this report was to describe a clinical case of autotransplantation with application of injected fibrin-rich plasma (i-PRF) and apical sealing with biodentine. Methodology: This clinical case report was used to conduct a descriptive study. Results: A 32-year-old patient was treated in whom the upper left third molar (2.8) was transplanted to the site of the first upper left molar (2.6). Despite the use of i-PRF and the sealing of the dental apex with biodentine, the procedure presented clinical failure. Conclusions: This outcome was associated with persistent gingival inflammation secondary to poor oral hygiene, which favored bacterial colonization of the gingival sulcus and compromised early periodontal reattachment. In addition, the behavior of endodontic sealant cement in a humid environment may have contributed to bacterial microfiltration and the persistence of the inflammatory process.

Comparison of apical microleakage in teeth obturated with AH Plus®, Vioseal®, and BioRoot RCS®, with and without gutta-percha cone(s): evaluation by root sectioning and optical microscopy

Introduction: apical sealing is a determining factor for the success of endodontic treatment, as it prevents the leakage of fluids and microorganisms into the root canal system. Objective: The objective of this study was to compare apical microfiltration in filled teeth with the sealants AH Plus®, Vioseal® and BioRoot RCS®, with and without the use of gutta-percha cone(s), evaluation by root sections and light microscopy. Methodology: An in vitro experimental study was conducted using 30 human teeth extracted from uniradicular teeth, which were subjected to a standardized protocol of instrumentation and endodontic filling. The samples were randomly divided into six groups (n=5): AH Plus with gutta-percha, AH Plus without gutta-percha, Vioseal with gutta-percha, Vioseal without gutta-percha, BioRoot RCS with gutta-percha, and BioRoot RCS without gutta-percha. Subsequently, the teeth were subjected to a cutting process and evaluated by immersion in 2% methylene blue, recording the penetration of the dye at the apical level. Results: To determine whether the use of gutta-percha cone(s) influences apical microfiltration when different endodontic sealants are used. Conclusions: The apical sealing capacity was related to the intrinsic properties of the endodontic sealant. AH Plus® and Vioseal® showed less apical microfiltration, while BioRoot RCS® showed greater susceptibility to dye penetration and material resorption, with no evident influence of the use of gutta-percha cone(s).

Clinical and radiographic evaluation of endodontic treatments: a case series

Tue, 28 Apr 2026 00:00:00 +0000

Introduction: the success of endodontic treatment depends on multiple factors, such as disinfection of the root canal system, quality of the filling, and coronal rehabilitation, evaluated using clinical and radiographic criteria. However, anatomical, microbiological and procedural variables can influence prognosis, conditioning favorable or unfavorable results in endodontic therapy. Objectives: the objective of this study was to evaluate clinically and radiographically the success and failure of endodontic treatments through a series of clinical cases. Methodology: a retrospective descriptive case series study was conducted in patients treated at the postgraduate course in endodontics at the Catholic University of Cuenca, Ecuador. Treatments included chamber access, biomechanical instrumentation, irrigation with 5.25% sodium hypochlorite, use of intracanal medication with calcium hydroxide in indicated cases, and filling with gutta-percha and sealant cement. In specific situations, retreatments, management of accessory canals, instrumentation of complex anatomies, and use of bioactive materials were performed. Clinical and radiographic follow-up allowed the evolution of periapical lesions to be assessed. Results: the results using quantifiable parameters showed that most cases presented resolution of clinical symptoms and signs of periapical bone repair. Factors such as the location of unidentified ducts, adequate management of complications, and effective disinfection positively influenced the prognosis. However, bacterial persistence and anatomical complexity were associated with unfavorable outcomes. Conclusions: concluding that the success of endodontic treatment requires a comprehensive approach based on accurate diagnosis, anatomical knowledge, adequate protocols, and long-term clinical/radiographic follow-up.

Apical surgery in a tooth with root perforation: therapeutic approach and clinical results. A case report

Karina Estefanía Saldaña Ayala, Felipe Guido Rodríguez Reyes — Tue, 28 Apr 2026 00:00:00 +0000

Introduction: Root perforations represent one of the most challenging complications in endodontics, especially when located in the middle or cervical third, where the prognosis tends to be guarded. The incorporation of bioceramic materials significantly improves the success rate in sealing perforations, thanks to their biocompatibility and ability to induce tissue repair. Objective: To present the clinical and microsurgical management of a buccal and distal root perforation in tooth 2.1, previously treated, as well as its clinical and radiographic evolution at six months. Materials and methods: Endodontic retreatment was performed using a vertical compaction technique, followed by apical microsurgery for perforation sealing with Biodentine® (Septodont, France). Retrograde preparation was performed with NSK ProUltra® ED45 ultrasonic tips (NSK America Corp., USA). Clinical, radiographic, and tomographic findings were documented, and follow-up examinations were performed at 15 days, 1 month, and 6 months. Results: The patient recovered well, without pain or inflammation. Percussion and palpation tests were negative, and the follow-up tomography scan showed a significant reduction in the periapical lesion and reparative bone formation. Conclusions: Although multiple root perforations present a guarded prognosis, the application of microsurgical techniques and bioceramic materials allowed for the preservation of the tooth and the achievement of a satisfactory functional and aesthetic repair.

Digital planning and 3D surgical guide in dental autotransplantation: a literature review

Juan David Donoso Vega, Felipe Guido Rodriguez Reyes — Thu, 07 May 2026 00:00:00 +0000

Introduction. Dental autotransplantation is a biologically predictable procedure when periodontal ligament vitality is preserved and extraoral exposure time is minimized. Digital planning, cone-beam computed tomography (CBCT), 3D surgical guides, and three-dimensional printing have improved the accuracy and predictability of this procedure. Objective. To analyze the application of a digital workflow using CBCT, intraoral scanning, and 3D-printed surgical guides in the planning and execution of dental autotransplantation, evaluating their contribution to surgical precision and periodontal tissue preservation. Methodology. An initial literature review on digitally assisted dental autotransplantation was conducted. Subsequently, four clinical cases planned to use a digital workflow are presented, that included CBCT, intraoral scanning, and 3D-printed surgical guides in patients aged 25, 28, 31, and 33 years. Results. All procedures showed extraoral exposure times of less than one-minute, functional stability, and no signs of root resorption or ankylosis during follow-up. Conclusion. The digital workflow applied to dental autotransplantation demonstrates high efficacy across different age groups and anatomical scenarios, enhancing surgical precision, preserving the periodontal ligament, and standardizing clinical protocols.
