Uso do metronidazol como medicação intracanal em dentes com necrose pulpar e reação periapical – relato de caso
Abstract
O objetivo desse trabalho foi comparar dois tratamentos endodônticos realizados em dentes com abscesso periapical crônico, em um mesmo paciente, empregando-se medicações intracanais diferentes. Para isso foram relatados dois casos clínicos de tratamentos endodônticos em dois dentes (31 e 41), nos quais foram empregados a mesma técnica de preparo biomecânico e obturação, variando apenas a medicação intracanal, pois no dente 31 foi empregada uma pasta a base de hidróxido de cálcio (Calen) e no dente 41, o metronidazol na forma de gel ginecológico. Após um ano de proservação dos tratamentos realizados, verificou-se reparação dos tecidos periapicais em ambos os dentes, concluindo-se que, nesse caso, a variação da medicação intracanal não interferiu no resultado do tratamento instituído e que o metronidazol pode ser uma alternativa viável como coadjuvante na terapia endodôntica desse tipo de patologia.
UNITERMOS: hidróxido de cálcio; medicação intracanal; metronidazol; reação periapical.
SUMMARYM
The aim of this work was to compare two endodontic treatments in teeth with cronic periapical abscess, in the same patient, using different intracanal medications. This two clinical cases are reported of endodontic treatments in two teeth (31 and 41), in which was used the same technique of biomechanic root preparation and obturation, varying only the intracanal medication. In the tooth 31 a paste based on calcium hidroxide (Calen) was applied and in the tooth 41 was used metronidazol in the form of a gynaecological gel. After 1 year of following up, the repair of periapical tissue of both teeth was evaluated. In conclusion, the variation of the intracanal medication did not interfere with the results of the treatment. The metronidazol can be a viable alternative as a coadjuvant in the endodontic treatment of this type of pathology.
UNITERMS: calcium hidroxide; intracanal medication; metronidazol; periapical reaction.
