Abstract

Objective: To evaluate the radiographic quality of endodontic treatments and their respective coronal restorations, correlating it with periapical status.

Material and method: The root filling quality of four hundred and sixteen teeth was carefully evaluated regarding three radiographic parameters: i) apical extension, ii) homogeneity and iii) taper, being E0, E1 and E2. E0 and E1 corresponding to sharp and mild deviation from normality, respectively; while E2 corresponding to the gold standard. Due to the combination of the assigned scores, filling was classified as perfect (PF), with three E2 scores; satisfactory (ST), with two E2 scores; or deficient (DF), with one or no E2 score. In addition, periapical status was considered to be a healthy periodontium; thickening of the periodontal ligament and presence of apical periodontitis. Coronary restorations were classified according to the presence and type of restoration. Associations between variables were analyzed using Spearman's Correlation test (p<0.05).

Result: Two hundred and twenty-one teeth had DF filling (53.1%). The apical extension was the parameter with the highest number of E0, accounting for 38.94% of assigned scores. Individually, the observed parameters did not show statistically significant association with periapical status (p>0.05); however, it was significantly associated with the general filling quality (p=0.021).

Conclusion: Fillings presented low quality standard, being the most critical parameter, negatively influencing the periapical status of the entire sample.

Resumo

Objetivo: Avaliar a qualidade radiográfica de tratamentos endodônticos e suas respectivas restaurações coronárias, correlacionando-os ao status periapical.

Material e método: A qualidade da obturação de quatrocentos e dezesseis dentes foi criteriosamente avaliada em três parâmetros radiográficos: i) limite apical, ii) homogeneidade e iii) conicidade, sendo E0, E1 e E2. E0 e E1 corresponderam a acentuado e suave desvio da normalidade, respectivamente; enquanto E2 correspondeu ao padrão-ouro. Em função da combinação dos escores atribuídos, a obturação foi classificada em perfeita (PF), com três escores E2; satisfatória (ST), com dois escores E2; ou deficiente (DF), com um ou nenhum escore E2. Além disso, o status periapical foi considerado como periodonto sadio; espessamento do ligamento periodontal e presença de periodontite apical. Restaurações coronárias foram classificadas quanto à presença e tipo de restauração. As associações entre as variáveis foram analisadas através do teste de Correlação de Spearman (p<0.05).

Resultado: Duzentos e vinte e um dentes apresentaram obturação DF (53.1%). O limite apical foi o parâmetro com maior número de E0, perfazendo 38,94% dos escores atribuídos. Individualmente, os parâmetros observados não apresentaram associação estatisticamente significativa com o status periapical (p>0.05); entretanto, o mesmo associou-se significativamente com a qualidade geral da obturação (p=0.021).

Conclusão: As obturações apresentaram baixo padrão de qualidade, sendo o parâmetro mais crítico, influenciando o status periapical de toda a amostra.
