Comparative Evaluation Of Accuracy Of Dental Operating Microscope With Conventional Vernier Caliper In Conservation Of Tooth Structure For Root Canal Treatment


European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 7, Pages 1569-1575

Background : The endodontic access cavity design directly relate to the identification and negotiation of the canals and allow straight line accessibility and visibility of the canals facilitating proper preparation. By introducing dental operating microscope and the accompanying capability of inspecting the root canals – ‘both orthograde and retrograde.’ This study is to determine the difference between the location and the difference in the access cavity for the conservation of the tooth structure.
Materials and methods: Thirty mandibular first molars were selected which were scheduled for the root canal treatment. The endodontic access cavity was prepared by using#4 carbide bur or #557 tapered bur. Three canals were located after the completion of the access opening. The samples were measured simultaneously with operating microscope and Vernier caliper. The inter orifice distance is measured and compared between the groups.
Results: Detection rate between the difference among the groups by operating microscope and Vernier caliper showed a non-significant difference between the groups only the mesiolingual orifice showed a significant difference. The microscopic method could more accurately detect orifices statistically than the other method.
Conclusion: Under the condition of this study access opening done under the microscope done shows more conservation of the tooth structure.

Rubber dam was introduced by Dr.Barnum in the 1860 s, the main advantage of using rubber dams in endodontics include patient protection from medicaments, aspiration of endodontic instruments, tooth debris, and irrigating solutions. The aim of the study to determine the prevalence and frequency of rubber dam usage during endodontic procedures among dentists in the state of TamilNadu, India.A survey was conducted among 101 dentists in the state of Tamil Nadu, India by preparing a set of questions, and the answers were collected through an online survey method.In this survey, 82.2% feel comfortable to use a rubber dam,36.6% never use a rubber dam to pediatric patients,89% always use a rubber dam to adult patients,61.4% not using rubber dam for all cases of RCT,73.8% need to gain knowledge about rubber dams through training programs,23.8 % told patients discomfort was a reason for not using a rubber dam, 80.2% not using rubber dam while taking X- rays,45.5% take more than 5 mins for applying a rubber dam to patients,63.4% told it is easily available for clinical usage.The present survey shows there is a low prevalence of its usage during endodontic treatment. Greater emphasis should be placed on the advantages of using rubber dams in clinical dentistry at dental school and through continuing dental education for practitioners to update their knowledge

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.
