Aims and Objectives:The purpose of the study was to evaluate and compare the microhardness of enamel after the application of anticay on bleached enamel with fluoride containing and fluoride free bleaching agent.Materials and Methods:Twenty freshly extracted teeth decoronated and divided mesiodistally into two halves were randomly divided into five groups with 10 samples in each group. The enamel surface was treated as follows: Group 1 - no treatment, Group 2 - fluoride free bleaching agent, Group 3 - fluoride containing bleaching agent, and Group 4 - fluoride free bleaching agent followed by anticay application. The samples were subjected to indentation to test the microhardness using Vicker's hardness analyzer.Conclusion:Enamel microhardness significantly increased in samples where anticay was used after the application of bleaching agent.

Endodontists belong to the category of specialist dentists who depend much on dental radiography. Starting from the stage of disease diagnosis, radiography is of much importance in different stages of endodontic therapy, and further on radiographic evaluation is a tool for assessment of endodontic treatment. There is a heavy dependency on dental radiography in some form or other in the speciality of endodontics. As is the case with any ionizing radiation, radiation hazard is a phenomenon that matters a lot to this group of dental professionals. There needs to be a change in our attitude toward radiation safety measures, as many of our professional colleagues are seen much not to be bothered about the cumulative outcomes of radiation hazard, which can create havoc in our professional and personal lives. This article outlines the potential hazards that can happen by routine radiographic utilization in endodontic setup and tries to highlight the measures that need to be taken to mitigate the negative effects.

Proper knowledge of the internal anatomy of tooth is essential for the long-term success of endodontic treatment. Mandibular premolars exhibit a greater variation in their internal morphology due to the occurrence of additional roots and root canals. This article showcases two case reports of successful endodontic management of mandibular premolars with three roots and three canals. A detailed diagnosis of symptomatic irreversible pulpitis with apical periodontitis was made through clinical and radiographic examinations. Endodontic management was carried out successfully and the patient was evaluated.
