Therefore, most countries put physical distancing measures (e.g., closing of public, cultural, and educational institutions) in place to decelerate the infection rate. Consequently, dental education at universities worldwide is strongly affected by the COVID-19 pandemic. The present study was done to know the effect of COVID-19 pandemic on dental education. Materials and Methods: A self-designed, structured, online questionnaire of 22 close-ended questions was generated and distributed among the undergraduates and postgraduate dental students in Bangalore city. A total of 450 forms were sent through online by messages, WhatsApp, and emails. Online consent was obtained before participation in the study and it was mandatory to answer all questions. Data obtained were subjected to descriptive and inferential statistics, and significant proportions were available. The level of significance was considered as P ≤≤≤ 5. Results: The study showed that in this pandemic, 73.4% of the students feel e-learning as a boon for learning dental students, but 87.1% of students feel classroom lectures are more interactive compared to online lectures. About 12.4% of the students felt difficult to access the Internet for online classes, whereas 87.6% of students had access. Students feel understanding clinical procedures is difficult through e-learning; hence, 83.6% of students search web for better understanding. Almost 92.5% of the students feel they are lacking clinical experience due to online classes. Conclusion: COVID-19 has definitely affected the world; similarly, it has affected the clinical practice of dental students in dental schools. As education continues through e-learning, still, few students are deprived of education due to access to the Internet.","PeriodicalId":14257,"journal":{"name":"International Journal of Preventive and Clinical Dental Research","volume":"116 1","pages":"78 - 80"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83082781","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}

An important anatomic variant in root canal morphology, the C configuration, presents as a thin fin connecting the canals with a predilection for mandibular second molars. Early recognition of the C-shape becomes imperative for its successful management. Newer diagnostic tools have facilitated a more precise diagnosis of this condition. Clinical and radiographic diagnoses can aid in the identification and negotiation of the fan-shaped areas. The inaccessible areas and unique canal patterns make provision of optimum treatment quality a highly challenging proposition. Successful endodontic therapy of this canal configuration can be achieved with rotary and hand instrumentation assisted with ultrasonics.","PeriodicalId":14257,"journal":{"name":"International Journal of Preventive and Clinical Dental Research","volume":"42 1","pages":"81 - 84"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85581902","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}

Color changes have been considered as the major problem of dental restorations. Long-term usage of pediatric liquid medications can stain the tooth as well as the restorative materials whose longevity and acceptability are directly proportional to its color stability. Aim: The present study aims to evaluate and compare the effect of pediatric drugs on the color stability of different esthetic restorations. Methodology: Three different restorative materials such as glass-ionomer cement, composite, and ACTIVA KIDS were used to prepare a total of 150 (50 from each) specimens. These specimens were divided into five experimental subgroups (n = 10), which were immersed in 5 different liquid medicines. The color stability of all specimens was evaluated by colorimeter before and after the immersion period. Results: Composites in iron supplements showed the highest color changes, and the least changes were seen in the ACTIVA KIDS - Ibuprofen group.
