Bioblock technique to treat severe internal resorption with subsequent periapical pathology: a case report

Abstract

A variety of therapeutic modalities can be used for the endodontic treatment of a traumatized tooth with internal root resorption (IRR). The authors present a case report of the successful restoration of a traumatized upper central incisor that was weakened due to severe IRR and subsequent periapical lesion formation. A 20-year-old female patient was referred to our clinic with severe internal resorption and subsequent periapical pathosis destroying the buccal bone wall. Root canal treatment had been initiated previously at another dental practice, but at that time, the patient's condition could not be managed even with several treatments. After cone-beam computed tomography imaging and proper chemomechanical cleaning, the tooth was managed with a mineral trioxide aggregate plug followed by root canal filling using short fiber-reinforced composite, known as the Bioblock technique. This report is the first documentation of the use of the Bioblock technique in the restoration of a traumatized tooth. The Bioblock technique appears to be ideal for restoring wide irregular root canals, as in cases of severe internal resorption, because it can uniquely fill out the hollow irregularities of the canal. However, further long-term clinical investigations are required to provide additional information about this new technique.

Evaluation of microhardness of short fiber-reinforced composites inside the root canal after different light curing methods – An in vitro study

“…These materials, when used with specific techniques, enhance the physical properties of ETT more effectively than conventional FRC post solutions [25,26]. One of the primary challenges in applying SFRC J o u r n a l P r e -p r o o f within the root canal, either in bulk (Bioblock technique) [22,26,27] or in a layered manner [29], is ensuring adequate light curing of these materials intraradicularly, occasionally at a depth of 6-8 mm apical to the CEJ. In previous publications, an FRC post (GC Fiber Post 0.8 mm, GC Europe, Leuven) was employed to transmit light from the curing unit [25,26,29,38].…”

“…Currently, two prominent direct methods for crafting personalized FRC posts are FRC post relining [12,[18][19][20][21] and the Bioblock technique [22][23][24][25][26].…”

Aspergilose – Relato De Caso

“…Já a reabsorção radicular interna é uma situação rara, comumente referida como uma reabsorção intracanal, resultando em distrofia pulpar que leva à destruição dos tecidos duros pelos osteoclastos (PATEL et al, 2010;NILSSON et al, 2013;SUBAY;SUBAY, TUZCO, 2018). Tem sido definida como um defeito localizado na face interna da raiz, ocasionada por diferentes fatores etiológicos, entre eles estão a inflamação pulpar crônica, traumas e necrose (KAVAL; GÜNERI; ÇALISKMAN, 2018;FRÁTER;SÁRY;GAROUSHI, 2020). Geralmente é assintomática, sendo diagnosticada casualmente através dos exames radiográficos de boca inteira de rotina (DAGNA, 2016).…”

Fatigue performance of endodontically treated premolars restored with direct and indirect cuspal coverage restorations utilizing fiber-reinforced cores

“…The failure of conventional FRC posts to reinforce premolar teeth may have multiple reasons: their inadequate fit in the cervical region of the canal (leading to an increased amount of luting cement) [23,24], poor bonding of the post material to the luting cement [25,26], or even the biomechanically inadequate position of the fibers inside the canal [27]. Aiming to solve the above-mentioned shortcomings, the authors have proposed the Bioblock technique for the individualized restoration of irregular root canals [28][29][30]. In many cases, the Bioblock technique, utilizing either packable or flowable short fiber-reinforced composite (SFRC), has shown superior results compared to FRC posts [28,29].…”
