“…The overfilling can be observed due to the overestimation of working length, the apex locator may give false results in roots with apical resorption, overpreparing of the canal, incorrectly matched master apical cones, and excessive pressure on the spreader during the lateral condensation technique, especially after rotary instrumentation [ 27 ]. Additionally, the final obturation of the root canals beyond the apex may occur more often in the case of periapical tissue inflammation [ 48 ]. It should be emphasized that the small extrusion of a sealer is generally well-tolerated by the periapical tissues [ 49 , 50 , 51 ].…”

The Assessment of Quality of the Root Canal Filling and the Number of Visits Needed for Completing Primary Root Canal Treatment by Operators with Different Experience

The main goal of root canal treatment (RCT) is to eradicate or essentially diminish the microbial population within the root canal system and to prevent reinfection by a proper chemo-mechanical preparation and hermetic final obturation of the root canal space. The aim of this study was to assess the quality of the root canal filling and the number of visits needed for completing RCT by operators with different experience, including dentistry students (4th and 5th year), general dental practitioners (GDPs), and endodontists. Data from medical records of 798 patients were analyzed, obtaining 900 teeth and 1773 obturated canals according to the inclusion and exclusion criteria. A similar number of teeth was assessed in each group in terms of density and length of root canal filling and number of visits. The larger number of visits and the lower quality of treatment was observed for 4th year students than for other groups (p < 0.05); in contrast, the endodontists needed the lowest number of visits to complete RCT and more often overfilled teeth than other operator groups (p < 0.05). Interestingly, no statistical difference in quality of root canal filling was noted between 5th year students, GPDs and endodontists. The treatment of lower teeth demanded statistically more visits than that of upper teeth (p < 0.05). The results of the study emphasize that most of the root canal filling performed by operators was considered adequate, regardless of tooth type, files used and number of visits.

“…Compared with in vitro cell experiments and animal experiments, it was more intuitive. In a follow‐up study report on root canal sealer beyond the apical foramen, the researchers conducted a long‐term follow‐up of 6 cases, and the results showed that in all cases the excess sealer was absorbed, and the periapical tissue was healed [73]. Another case study of overfill reported that the healing of the root apex was not related to the type of sealer but was related to tooth position [74].…”

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

et al. 2022

The function of root canal sealer was to achieve an appropriate three‐dimensional filling effect by filling the root canal and some irregular lumen, thereby inhibiting the residual bacteria. There were many types of sealers, but research to find the most suitable ones was still ongoing. In recent years, researchers had continuously improved the performance of sealers by developing new sealers or adding active ingredients to the sealers. However, most sealers exhibit varying degrees of cytotoxicity and tissue responses, which affect clinical therapy efficacy. This review describes different technical approaches, and recent research progress in the biocompatibility evaluation of root canal sealers and provides brief insights into this field by summarising the performance studies of different root canal sealers.

“…Cerca de 60% das falhas do canal radicular ocorrem devido a obturações incompletas (Saatchi et al, 2011). Portanto, o objetivo da obturação é fornecer uma vedação impermeável a fluidos dentro de todo o sistema de canais radiculares, para evitar a microinfiltração oral e apical (Ceribelli et al, 2013;Murata et al, 2013;Malagnino et al, 2021). Para atingir esse objetivo, grandes variações entre o instrumento de formatação e os cones GP devem ser evitadas (Bajaj et al, 2017;Mamede et al 2011).…”

A guta-percha é considerada o melhor material para obturação do canal radicular e o cumprimento das normas internacionais para sua fabricação é de extrema importância para a etapa de obturação. Esta pesquisa teve como objetivo avaliar o diâmetro da ponta e conicidade de cones acessórios de guta-percha não estandardizados tamanho M de três diferentes marcas comerciais brasileiras: Tanari, Odous e MK Life. Para tanto, 20 cones de cada marca foram fotografados, com auxílio do de um mini microscópio com câmera digital acoplada, para obter medições dos seguintes parâmetros: diâmetro da ponta (D0), diâmetro a 3 mm da ponta (D3), diâmetro a 16 mm da ponta (D16) e conicidade (C). As medidas encontradas foram submetidas a análises estatísticas e comparações entre os grupos das médias de cada parâmetro avaliado. As especificações ANSI/ADA números 57 e 78 foram utilizadas como referências para a análise da estandardização dos cones testados. Os respectivos valores médios de D0 e conicidade encontrados foram 0,05 mm e 0,07 para os cones Odous, 0,15 mm e 0,05 mm para os cones da fabricante Tanari, e 0,07 mm e 0,05 mm os cones da marca MK Life. De posse dos resultados, foi possível concluir que não existe padronização dos cones obturadores M entre as marcas avaliadas com discordância do preconizado pelas especificações ANSI/ADA.
