“…Atualmente, a ADA e a ISO são duas organizações internacionais que padronizam os cones GP, e de acordo com as normas vigentes, o diâmetro aceito do cone GP pode variar de 0,005 a 0,007 mm. Tal variação significa que o cone de um determinado tamanho pode ter um tamanho acima e/ou abaixo, por exemplo, o cone ISO # 25 pode ter ISO # 30 ou ISO # 20 (Bueno et al, 2017).…”

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.

“…There are reports in the literature on the wide variability in diameter and taper of commercially available gutta-percha points [15][16][17]. However, only a few papers address the accuracy of the greater taper GP points [18][19][20][21][22]. This study was performed to evaluate the ISO size compliance of GP greater taper points.…”

Introduction and Objective.When filling root canals with gutta-percha points (GP), good adaptation of the point to the apical diameter must be achieved through the use of a point corresponding to the size of the master apical file (MAF). GP points with a greater taper, designed to fit into root canals shaped with files with a greater taper, are currently in common use. The study was performed to evaluate the ISO compliance of GP greater taper points (4% and 6%). Materials and Method. Two boxes of GP in sizes 20, 30 and 40 (Dentsply Maillefer, Switzerland) with a taper of 4% (GP 4% group) and 6% (GP 6% group) were used. The percentage of GPs conforming to the ISO size and those not conforming to the ISO size was determined by assessing the fit of the GP apex diameter (D0) with an endodontic gauge (Dentsply Maillefer, Switzerland). Data were analysed using the chi2 test with a significance level of 0.05. Results. Overall, 58.9% of the GP points assessed were in accordance with the ISO size. Depending on the size (20, 30, 40 according to ISO), compliance was 75%, 52.5% and 44.4% in the group GP 4%, and 87.5%, 32.5% and 60% in the group GP 6%, respectively. The results were statistically significant in the GP 4% (p<0.0001) and GP 6% (p<0.05) groups. In both groups, standardisation of greater taper GP was most accurate at size 20. There were no statistically significant differences between the number of GP points with correct diameter between groups GP 4% and GP 6%. Conclusions. The study demonstrated the presence of differences between the ISO size and the actual size of the greater taper GP points. Therefore, the calibration of greater taper GP points before root canal filling should be a routine procedure.
