Impression making itself depends on the type of material and the impression technique used to record the details. Various combinations of material and the technique have been described in the literature.Aim: To evaluate the effect of three different impression techniques on the marginal fit of computer-aided designed/computer-aided manufactured (CAD/CAM) single unit composite fixed dental prostheses (FDP), different consistencies of addition silicone impression material and different tray design were utilized.Method: Impression of prepared tooth on typodont was made using Matrix impression system, two-step putty wash technique, and individual tooth tray technique. Prosthesis was fabricated using CAD/CAM technology and marginal accuracy was evaluated using scanning electron microscopy (SEM).Result: In the present study, the matrix impression system resulted in less microgap in both mid-buccal and mid-mesial region, whereas putty wash technique showed very high standard deviation in the interproximal region.Conclusion: Matrix impression system had the best results at both mid-buccal and mid-mesial position with least marginal discrepancy.Clinical implication: The findings of this study could be used by clinicians to help them choose the viscosity of polyvinylsiloxane material and impression techniques for FDP that will result in high-accuracy impressions and well-fitting prostheses.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current evidence clearly states an association between oral diseases and diabetes mellitus with manifestations like periodontitis, peri-implantitis, xerostomia, etc. Despite this obvious link, knowledge, awareness and attitude of general population towards this are not fully understood.Aims: To assess public knowledge and awareness on association between diabetes and oral health and assess their attitude towards oral hygiene care and maintenance.Methods and materials: A three-part structured questionnaire was developed with multiple choice questions and circulated among patients visiting a private dental college. A total of 502 questionnaires were evaluated, and results were statistically analysed.Statistical analysis used: Student-t test and Chi-square test using SPSS software.Results: Majority of the participants were male and lived in urban area. 41.8% respondents had diabetes, out of which 86.7% had no awareness of the type. A significant number of non-diabetic individuals had awareness of excessive sugar intake as a cause of diabetes. Greater number of diabetic patients (96.7%) reported dry mouth, whereas only 53.3% had periodontal complications. 90% participants use tooth brush as oral hygiene aid. Only 10.6% participants follow regular dental visits. Majority of subjects (60.6%) listed their friends and family as major source of information.Conclusion: More people are aware of systemic complications of diabetes as compared to oral problems. A better interdisciplinary relationship is required among dentists and physicians to improve knowledge and awareness of general population.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fruitful method to deal with strong willed children is to violate the causal relationship by some magic tricks from preventive via curative to his/her follow ups visits. Tricks can be applied at three levels of their visit. Level 1 is preoperative tricks, which includes the preventive measures that teach and educate children for good oral health. Level 2 is operative tricks, which involves child preparedness for successful dental procedures. Level 3 is postoperative tricks, which involve positive reinforcement for regular follow ups.

COVID-19 infection results in an immunocompromised state due to the steroid therapy administered to patients and the infection itself. The presence of co-morbidities makes patients more susceptible to acquire mucor infection. Mucormycosis spreads rapidly, associated with aggressive angioinvasion, leading to ischemic necrosis of surrounding tissues. Due to its rapid spread and angioinvasion, mucormycosis is associated with increased mortality and morbidity.Treatment planning: Early diagnosis and proper treatment planning are crucial to prevent further spread of infection, where dentists play an important role.Discussion: This case series is mainly focused on patients reported to the oral medicine department with complaints of discomfort or mobility of teeth in the maxillary region while explaining the role of dentists in diagnosing and treating the disease.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reduction in permeability can improve prognosis of these teeth. Therefore, this study was designed to compare the effect of 940 nm diode laser and dentin bonding agent on the dye penetration of furcation area in primary molars.Material and methods: Thirty teeth were divided into three groups, that is, Group 1 (control group), Group 2 (dentin bonding agent applied over floor of pulp chamber), and Group 3 (diode laser irradiated over floor of pulp chamber). The samples were prepared and seven from each group were tested by dye penetration and three were sent for scanning electron microscopy. Rise in temperature in the perifurcal area was also recorded at the time of laser irradiation. Dunn's pair-wise comparison analysis was used for the analysis for the difference in dye penetration among the group.Results: : The maximum rise in temperature recorded postirradiation was 6.90C. Dye penetration was significantly reduced in Group 2 Dentin bonding group (DBG) as compared to control group (P = 0.0025). Reduction in permeability was observed in Group 3 Laser group (LG) but this was not statistically significant (P = 0.197). Scanning electron microscope revealed open dentinal tubules in Group 1. There were no open dentinal tubules in Group 2, while Group 3 had sealed dentinal tubules with glass-like surface over the region.Conclusion: Dentin bonding agent led to substantial decrease in dye penetration of furcation area of primary molars.
