Evaluation of regression of periradicular lesions submitted to endodontic treatment in a single session and filled with PBS CIMMO Hp and Endofill cement: Clinical case report

Endodontic treatment has as main objective the cleaning and modeling of the root canal, thus removing the microorganisms that provide the infectious condition through chemical and mechanical preparation. The objective of this study is to present a case report on the evaluation of the regression of periradicular lesions submitted to endodontic treatment in a single session and filled with PBS CIMMO Hp and Endofill cement. It is a study with an applied research principle, a qualitative and quantitative approach, with an exploratory character, carried out on a 29-year-old female patient who had two uniradicular teeth (8 and 9) with periradicular injury caused by an infectious and asymptomatic process. Endodontic treatment in a single session was performed simultaneously on the two dental elements with ProDesign S rotating files, localization of the working length through foraminal locator and irrigation with 2.5% sodium hypochlorite and final irrigation with 17% EDTA. After complete chemical-mechanical preparation, dental element 9 was filled with endodontic cement endofill and dental element 8 was filled with bioceramic endodontic cement PBS CIMMO HP. Radiographic follow-up was performed for a period of 1, 2 and 8 months in order to observe the repair process of the lesions and the regression of the periradicular lesion and it was observed that the regression of the periradicular lesions submitted to endodontic treatment in a single and filled session with cement PBS CIMMO Hp and Endofill were similar in the two dental elements. Given the context, it is possible to conclude that the type of endodontic cement did not interfere in the regression time of the periapical lesion.
