Background:The present study was undertaken for comparing the impact of desensitizing
agents on the retention of crowns cemented with luting agents.Materials & methods:20
freshly extracted mandibular molar teeth were selected. Storing of the tooth specimens in
the normal saline was done followed by thorough cleaning. All the specimens were divided
into two study groups as follows: Group 1: Glass ionomer cement (Control), and Group 2:
Glass ionomer cement (GC Tooth Mousse desensitizer). Crowns were fabricated and were
subjected under universal force testing machine. All the results were recorded in Microsoft
excel sheet and were analyzed by SPSS software.Results:Among the group 1, mean tensile
bond strength was 45.9 Kg while in the group 2, mean tensile strength was 44.2 Kg
respectively. While comparing statistically, non-significant results were
obtained.Conclusion:Application of desensitizing agents might be designated during
fabrication of crowns as it will not affect the retentive ability of the luting cements.

Endodontically treated teeth are more prone to fracture compared to vital teeth.Clinical outcome of endodontically treated teeth is influenced by a variety of factors, tooth position in the arch,number of proximal or occlusal contacts, type of abutment, crown placement, amount of tooth structure loss due to caries,previous restorations or endodontic access, trauma, and periodontal status.Theaim of the present study was to evaluate the number of patients reporting for post endodontic restoration after completion of root canal treatment to dental hospital. This is a retrospective study conducted during June 2020. Included patients who visited a dental hospital in chennai,India from June 2019 - March 2020. Data of patients was collected from case records, tabulated into excel sheets under headings age,gender,teeth no, patients reported back for post endodontic restoration.Then data was analyzed using SPSS software(23.0 version). Statistical analysis of the data was performed using the chi square test. In the present study 66.2% of patients reported for post endodontic restoration, 33.8% of patients did not report back for post endodontic restoration. Failure to report back for post endodontic restoration was less in the present study. Being busy with other activities and long distance were some reasons given by patients who failed to report back for post endodontic restoration.
