Eficácia de medicamentos fitoterápicos no retratamento endodontico

Abstract

Failures in endodontic therapy are frequent, and their etiology is diverse and ranges from unsatisfactory endodontic treatments to adequate treatments but associated with microbial, non-microbial, intrinsic or extrinsic factors. Thus, endodontic retreatment is a frequent practice in dentistry, requiring the removal of the root filling using solvents that are often toxic. The use of essential oils has been reported by the Chinese since 2000 a.C. with wide application for both aromatic and medicinal purposes. In this context, this work aims to use essential oils as an alternative to conventional endodontic solvents, focusing on a biocompatible substance, with low cytotoxicity and non-carcinogenic. Thus, this work evaluated the effectiveness of several essential oils, including Eucalyptus globulus, Melaleuca alternifolia, Citrus aurantium dulcis and Eugenia caryophyllus in dissolving the gutta-percha cone. The test was carried out in triplicate, the sample was composed of 54 gutta-percha cones that were initially weighed, then immersed in 2,5mL of test substance for 5 minutes, then dried at room temperature for 72h and weighed again, thus calculating the mass lost after exposure. The control group consisted of Eucaliptol® - Biodinamica and Chloroform. As a result, it was found that the essential oil Citrus aurantium dulciswas more effective than eucalyptol and statistically similar to chloroform. Eucalyptus globulusoil was superior to the Eucaliptol control and inferior to chloroform. Melaleuca alternifolia was similar to Eucaliptol and inferior to chloroform. The essential oil ofEugeniacaryophyllus performed worse. It is concluded that Citrus aurantium dulcis, Eucalyptus globulus, Melaleuca alternifolia oil presents itself as an alternative to conventional solvents.
