Tratamento endodôntico de incisivo com calcificação e desvio na trajetória do canal com uso do ed-file

Abstract

INTRODUCTION: Pulpal calcification is characterized by the deposition of calcium salts in the dental pulp tissue, often caused by trauma, deep caries, extensive restorations, or aging. The treatment of calcified root canals is complex due to anatomical difficulties, with the risk of perforations and deviations. In these cases, technologies such as computed tomography, ultrasound, and the ED File® adapter for mechanized files are essential, facilitating the preservation of the tooth and its function. OBJECTIVES: To report the endodontic treatment of a tooth with pulpal calcification and canal deviation, using the ED File® adapter to precisely insert the mechanized instrument, followed by coupling to the endodontic motor to facilitate access and instrumentation. METHODOLOGY: A left maxillary lateral incisor with pulpal calcification and canal deviation, diagnosed with asymptomatic apical periodontitis, was treated in two sessions. Cone-beam computed tomography was requested due to the absence of a canal outline on conventional radiographic examination. Treatment was performed using NiTi rotary instruments inserted with the ED File® adapter, allowing the endodontic motor to be coupled to the instrument already positioned in the canal. RESULTS: The technique with the ED File® ensured precise direction of the instruments to the original root canal, facilitating negotiation of the calcification. The use of the ED File® adapter prevented the mechanized instrument from deviating from the original trajectory, avoiding invasion of the pre-existing deviation, providing safer and more efficient mechanized instrumentation.
