“…A barrier of 5 mm MTA was created apically according to suggestions in the literature. 12 MTA as an obturation material is claimed to have numerous benefits, which include superb biocompatibility, a biologically acceptable seal and reduced cytotoxicity. 13 Bogen and Kuttler (2009) 14 advocate the use of MTA as a suitable obturation material after cleaning and shaping and even as a complete fill of the root canal system, which might ultimately increase the long-term prognosis and retention of the tooth.…”

The Human Immunodeficiency Virus (HIV) has been a focal point of investigation over the last few years. Consideration of endodontic treatment in an HIV-positive patient needs a calculated approach as the choice of materials and chemicals may influence the final result. A recent investigation showed that cases presenting with pre-operative pathology during examinations have a significantly lower prognosis after treatment. This clinical case report discusses the treatment approach of an upper left central incisor of an HIV-positive patient. The treatment approach and the outcome after a fifteenmonth follow-up period are outlined. Foreign bodies are sometimes lodged inside the root canal system of teeth and can be fortuitously discovered during dental examinations. In reported cases, children are among the patients more often affected by this phenomenon. 1 The reality is that these foreign bodies are not sterile and act as a potential breeding ground for organisms, which have the ability to cause infections and complications in the future. 1

Background: Mineral trioxide aggregate (MTA) becomes a hard mass after setting and making it difficult to remove and can cause significant problems in the retreatment process. The aim of this study was to evaluate the effect of different concentrations of hydrochloric acid (HCl) on MTA dissolution and its effect on dentin. Materials and Methods: In this in vitro study, 45 single-root premolars were selected. Artificially open apex was created in all samples with similar process. The samples were randomly divided into 4 experimental groups of 10, and a control group of 5. Four-millimeter thick apical plugs of Root MTA were placed in all samples in an orthograde manner. HCl was used at concentrations of 3.75%, 7.5%, 15%, and 22.5% (w/v) for the experimental groups and normal saline for the control group. Each sample was exposed to the desired solution for 15 min. Then, MTA retrieval and reaching the working length were attempted with k-file # 30. The times of each sample were recorded. Furthermore, after longitudinal incision of the roots with a disc, the dentin surfaces of canals were examined with a Dino-Lite microscope (×50). Results were analyzed by Shapiro–Wilk test and one-way analysis of variance tests. The level of significance P value was set at 0.05. Results: The lowest average time of reaching working length was observed with group 22.5% that was significantly lower than 15% and 7.5% concentrations (P = 0.005 and P = 0.011). Furthermore, by examining with ×50 of Dino-Lite microscope, no difference was observed on the canal walls. Conclusion: The optimum concentration of HCl was 7.5%. Furthermore, different concentrations of HCl had no significantly different effect on the dentinal canal wall using Dino-Lite microscope with ×50.
