ABSTRACT

This study aimed to analyze the level of radiopacity of different materials used in endodontic retrofilling procedure regarding the influence of humidity on solubilization over a period of 30 days. Material and methods: 10 specimens with 10 mm diameter and 1mm thick were made with each of the materials. The following retrograde filling materials were tested: glass ionomer Vitro Fil LC®, IRM®, MTA Angelus®, Sealer 26® and silver amalgam capsule DFL Alloy. These materials have been handled by a single operator, according to the recommendations of their respective manufacturers. The obtained specimens were surrounded by moist gauze and incubated in a heater for thirty days at 37°C and 100% humidity. The samples were x-rayed, via the digital system Digora Optime®, at three different moments: first, 15th, and 30th day of incubation. For the analysis of radiopacity of the samples, the shades of gray were measured through ImageTool® software. Results and Conclusion: Data were subjected to statistical analysis using ANOVA, repeated measures design, followed by Tukey test with a significance level of 5%. According to the results, it could be observed that the only tested materials that have undergone changes in radiopacity, in accordance with the period of incubation in humidity, were the glass ionomer Vitro Fil LC® and Sealer 26®.

Introduction: Periodontal and pulp tissues are closely related through communication pathways present in the periodontium. This interrelation supports the emergence of endo-periodontal lesions, caused by infectious and irritating products, triggering an inflammatory response Objective: The present study aim to report the treatment of a case of endo-periodontal lesion where endodontic treatment was performed prior to periodontal treatment. Case description: On clinical and radiographic examination, the patient was diagnosed with an endo-periodontal lesion on element 48. The proposed treatment plan was endodontics followed by subgingival scaling. Conclusion: Endodontic treatment associated with periodontal treatment led to the resolution of the case, being observed the absence of pain, absence of abscess/fistula, decreased probing depth and tooth mobility, in addition to bone gain seen radiographically.
