Avaliação clínica e radiográfica de dois tipos de cimentos obturadores usados no tratamento endodôntico de dentes decíduos necrosados após trauma com 1 ano de acompanhamento

Abstract

The endodontic treatment of necrotic primary teeth after trauma has been advocated for maintaining functional and aesthetic rules of these teeth the oral cavity. Various materials have been used for root canal filling of deciduous teeth, but none meets all the criteria for an ideal filling material. In view of the lack of consensus in the literature about the best filling material to be used for this purpose, the objective of this study was to compare two root canal filling materials used in endodontic treatment of necrotic primary teeth after trauma. The sample consisted of 31 teeth, and a total of 26 patients between 2 and 5 years old. The filling materials used were zinc oxide and eugenol (Group I) and Calen ® paste thickened with zinc oxide (Group II). The endodontic treatment was performed in two sessions with an interval of 30 days between them; Calen ® was used as a root canal dressing. Clinical success was evaluated by no pain, mobility, and fistula and radiographic success was based on the absence or reduction of lesion, absence of pathological root resorption and the presence of new bone formation. There was a success rate of 93.3% for Group I and 87.5% for Group II. The results were submitted to statistical analysis by Fisher test and there was no statistically significant difference between groups. It has been demonstrated that zinc oxide and eugenol and Calen paste thickened with zinc oxide can be indicated for endodontic therapy of deciduous teeth, and these two filling materials did not differ in the clinical success of treatment.
