Methods: This study was a cross sectional survey conducted by means of a confidential on-line survey on 174 Iranian dentists. COVID-19 related questions were divided to three parts: dentists’ perspective about their career future, virus contagion and concerns of getting infected COVID-19 from patients, and paucity of information and facilities to control the spread of the virus. Perceived stress and psychological flexibility were assessed by PSS (Cohen et al., 1983) and CFI (Dennis et al., 2010). To analyze data path analysis method was used. Results : Perceived stress significantly predicted psychological flexibility (both alternatives and control subscales) and COVID-19 factors related to dental work In addition, control subscale significantly predicted dentists’ concerns toward their career future and fear of COVID-19 contagion. Hence, control subscale of cognitive flexibility mediated the relationship of perceived stress and professional concerns of dentists during COVID-19 pandemic. Conclusion: Given these results, elevated stress during an infectious disease outbreak can effect (have impact on) perceived stress and professional concerns among dentists. Different aspects of dentists’ lives can be affected by those concerns and stress. Interventions to enhance the cognitive flexibility should be applied to reduce the psychological burden of the crisis for dentists.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45069211","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}

The present study aimed to evaluate common procedural errors that lead to lawsuits in dentistry. In the present cross-sectional study, all the patient files of three large dental clinics in Tehran were evaluated from 2014 to 2019, in which a dentist’s negligence had been confirmed by the specialty dental committee. Files with incomplete clinical data, without the dentist’s name, and the type of the lawsuit were excludeda and Finally, 107 lawsuit files were confirmed and entered the study. After extraction of the data from the existing files and completing the relevant checklist, data were analyzed with SPSS 23. Most lawsuits were of the therapeutic type (88 cases, 82%), with 34 cases (31.9%) , 26 cases (24.2%) and 19 cases (17.6%) related to prosthodontics, endodontics, and surgery, respectively. Most plaintiffs were 30–49 years of age (56 cases ,52%), and most were women (70 cases, 65%). Over half of the lawsuits had been filed against dentists with a job experience of <10 years and against general dental practitioners (81 cases, 76%). One of the most important ways to prevent errors leading to lawsuits is to increase dentists’ knowledge about previous lawsuits. Knowledge about the most common lawsuits and the provision of organizational guidelines will help manage and decrease such lawsuits.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70729472","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}

Motivating tobacco users through behavioral counseling is the mainstay for achieving tobacco abstinence. Research evidence suggests a larger role of dental professionals in motivating tobacco users to quit. The efforts of private dental practitioners in providing Tobacco Cessation Interventions (TCI) in their clinics need to be measured and acknowledged. Methods: A cross-sectional survey based on self-administered questionnaire with private dental practitioners was carried out in the state of Delhi, India. The main objectives of the survey were to assess the current practices and the barriers experienced in providing TCI by the participating dentists. Statistical analysis was conducted to find out the association between independent variables and the responses to questions on tobacco cessation. Results: The mean age and years of practice of 297 participating dentists was 37.2 (SD 9.8) and 11.9 (SD 9.5) years respectively. Most of them were graduate (N=204, 68.7%). Only 17.2% (N=51) of the participating dentists had undergone any training in providing TCI. Most of the dentists felt that the lack of proper training (N=146, 49.2%) and resistance by patients (N=185, 62.5%) are the main barriers in providing TCI. Younger dentists (<35 years) performed significantly better than older dentists in many parameters pertaining to attitude and practices of TCI in their clinics. Conclusion: This is a pioneer survey conducted on the issue of TCI provided by private dental practitioners of Delhi. The study results show that around 2/3rds of the participating private dental practitioners were providing TCI to their patients but there are certain barriers for its proper implementation. Therefore, there is an urgent need to remove these self-reported barriers and build self-confidence among the dentists for instituting effective TCI in their clinics.","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45579938","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}

Many factors have been demonstrated to influence the marginal seating and retention of crowns, such as size and shape of the prepared teeth, manipulation of the cement, retentive properties of the cement, cement film thickness, relieving space or venting for cement, cement application, and roughness of the dentinal surface. Optimum retention form is considered to be one of the most important principles of tooth preparation. The longevity of fixed prosthesis depends on the retention and marginal integrity of restoration. This study was done to evaluate, compare and correlate the marginal fit and retention for two different designs of die spacer. Materials and Method: The samples to be studied were divided into 2 groups of 15 each. Each having a different die spacer design.
