Objetivo: Avaliar a capacidade de preenchimento das Reabsorções Radiculares Internas artificiais por avaliação radiográfica e por método de corte com as diferentes técnicas (Condensação Lateral; Híbrida de Tagger; Cone Único) e diferentes cimentos (AH Plus® e BioRoot RCS®).
Métodos: Os 30 dentes foram decoronados para obter um comprimento de trabalho de 17mm. Posteriormente, realizou-se a instrumentação e procedeu-se ao protocolo de irrigação final. Foram seccionados com disco de carbono a 7mm do ápice e em cada fragmento realizou-se uma cavidade semiesférica. Foram unidos e procedeu-se à obturação com as diferentes técnicas.
Resultados: No grupo A, 0% obteve obturação total e 100% obturação parcial, sendo que todos os elementos obtiveram uma predominância de Core e 0% predominância de cimento obturador. No grupo B, 20% obteve obturação total e 80% obturação parcial, sendo que 80% obtiveram uma predominância de Core e 20% predominância de cimento obturador. No grupo C, 60% obtiveram obturação total e 40% obturação parcial, sendo que 30% obtiveram uma predominância de Core e 70% predominância de cimento obturador.
Conclusões: A técnica com melhor capacidade de preenchimento é a Técnica de Cone Único associada com o cimento obturador BioRoot RCS®, visto que apresentou uma maior percentagem de obturações totais, comparativamente com as Técnicas de Condensação Lateral e Híbrida de Tagger. Outro parâmetro relevante é a predominância de cimento obturador ser mais elevada na Técnica de Cone Único, tendo o BioRoot RCS® uma dureza maior e uma contração do material menor comparativamente ao AH Plus®.
Objective: To evaluate the filling capacity, by radiographic evaluation and by cutting method, of artificial Internal Root Resorptions with different techniques (Lateral Condensation; Tagger Hybrid; Single Cone) and different cements (AH Plus® and BioRoot RCS®). Methods: The 30 teeth were decoroned to obtain a working length of 17mm. Subsequently, instrumentation was performed and the final irrigation protocol was carried out. They were sectioned with a carbon disc 7mm from the apex and a semispherical cavity was made in each fragment. They were joined and filled with different techniques. Results: In group A, 0% achieved total filling and 100% partial filling, with 100% teeth having a predominance of Core and 0% predominance of filling cement. In group B, 20% achieved total filling and 80% partial filling, with 80% teeth having a predominance of Core and 20% of filling cement. In group C, 60% achieved total filling and 40% partial filling, with 30% of teeth having a predominance of Core and 70% of filling cement. Conclusions: The technique with the best filling capacity is the Single Cone Technique associated with the BioRoot RCS® filling cement, since it presented a higher percentage of total fillings, compared to the Lateral Condensation Technique and Tagger's Hybrid Technique. Another relevant parameter is that the predominance of sealing cement is higher in the Single Cone Technique, with BioRoot RCS® having a higher hardness and a smaller material shrinkage compared to AH Plus®.
