Resumo

Objectivo

O objectivo deste estudo piloto in vitro foi avaliar a qualidade da obturação endodôntica do sistema de canais radiculares por três técnicas diferentes: condensação lateral convencional, híbrida de Tagger e Thermafil, com base em dois parâmetros – os espaços vazios remanescentes e a ausência ou presença de extrusão de material obturador.

Materiais e métodos

Prepararam-se 18 raízes mesiais de molares inferiores humanos com limas de Ni-Ti. Destas, 15 foram divididas aleatoriamente em três grupos e, em cada grupo, obturadas por cada uma das técnicas referidas. 3 raízes foram seleccionadas para testar o equipamento SkyScan® e as suas ferramentas de reconstrução e análise de imagem. As imagens foram captadas antes da preparação, após a preparação e após a obturação. O volume de espaços vazios remanescentes (mm3) determinado pelas imagens de micro-tomografia computorizada, e os valores de extrusão, foram analisados estatisticamente para um nível de significância de 0,05, ou seja, para um grau de confiança de 95% (teste de Kruskal-Wallis).

Resultados

Todas as técnicas apresentaram espaços vazios remanescentes sendo que a Thermafil foi a responsável pelo maior volume registado (mediana = 0,861mm3). Foi também a que se traduziu numa maior percentagem de extrusão (42,86% de um total de 46,70%).

Conclusão

A técnica de condensação lateral convencional apresentou os melhores resultados das três técnicas em estudo. A potencialidade do software de micro-tomografia computorizada merece ser explorada em estudos futuros.

Abstract

Aim

The aim of this in vitro pilot study was to evaluate the quality of root canal filling of three different techniques: lateral condensation, Tagger hybrid technique and Thermafil based on two parameters – voids (unfilled) areas and the absence or presence of extrusion of filling material.

Materials and methods

18 mesial roots of human mandibular molars were prepared using rotary Ni-Ti files. After a biomechanical preparation, 15 teeth were randomly allocated to three treatment groups and within each group, teeth were filled using one of the three above-mentioned techniques. Three teeth were used to test the equipment SkyScan® and his reconstruction and image analysis tools. The images were captured before preparation, after preparation and after filling. The volume of root filling voids (mm3) was determined by microcomputed tomography imaging and the extrusion values were statistically analysed at a significance level of 0,05, or, at a confidence level of 95% (Kruskal-Wallis test).

Results

All techniques showed filling voids and the Thermafil was responsible for the highest volume recorded (median = 0,861mm3). It was also the one that resulted in a higher percentage of extrusion (42,86% of a total of 46,70%).

Conclusions

Lateral condensation showed the best results of the three studied techniques. The potentiality of the microcomputed tomography software deserves to be explored in future researches.
