Introduction. There is still no agreement as to which materials are best for final root canal fillings. Endodontal research remains focused on finding a synthetic material that lacks antigenic properties when implanted in vital tissue. This report describes how two different types of silers affect periapical tissue. One contained epoxy resins (AH Plus), and the other contained calcium hydroxide (Apexit). We assessed the effect of these materials by observing clinical signs, sensitivity, and by analysis of radiological (RTG) scans done just before therapy, immediately after and at 12 months after. Methods. Our study included 53 patients of both genders with ages ranging between 15 and 50 years. All patients were diagnosed with acute or chronical periodontitis following endodontic therapy. One group of patients had a total of 26 teeth filled with AH Plus siler, while the second group had 27 teeth filled with Apexit siler. Patients were classfied according to their gender, morphological characteristics of their teeth, presence of spontaneous pain, oedema, sensitivity to vertical and horizontal percussion, and the presence or absence of fistulas. Results. Immediately after treatment and 12 months later, patients from both groups (teeth filled with either AH Plus or Apexit) experienced neither pain nor oedema. However, existing fistulas persisted in the majority of patients whose teeth are filled with Apexit. Percutory sensitivity persisted immediately after the treatment as well as 12 months later in half or more of the patients whose teeth are filled with Apexit. Pathological changes identified by RTG were 30% more common in the Apexit patient group than in the AH Plus group immediately after treatment, and 50% more common at the 12 month follow up visit. Conclusion. From the results presented, we conclude that AH Plus siler is preferable to Apexit for endodontic treatment in periapical disease.
