Impression compound has been introduced for more than 100 years. Since then, it has been widely used to obtain a preliminary impression of the edentulous arch. Although the use of impression compound has declined markedly over recent years as newer materials have become available, the cost-effectiveness and desirable physical and mechanical properties make this material indispensable in developing countries and teaching institutions. Its high viscosity characterizes impression compound as a mucocompressive impression material, which enables the full depth of the sulcus to be recorded for the retention of complete dentures. Literature reviews revealed that most contact allergies to impression materials are towards polyether, very few are towards alginate and polysulfide, and no reported cases have been found toward impression compound. This case report demonstrates a recent rare case of contact allergy towards impression compound during a routine impression taking for a fully edentulous arch in a 61-year-old woman. The patient developed symptoms of an allergic reaction, and the management of the condition was described.
Introduction: Undergraduate (UG) dental students are trained for fixed prosthodontics course clinically in teaching institutions during the clinical years. However, there is a lack of objective data on the quality of fixed prostheses preparations done by UG students on their patients for academic and clinical staff. Aim: To evaluate the full-coverage crown preparations performed by UG dental students in the university clinical teaching programme. Materials and Methods: This study was a clinical audit done in the Faculty of Dentistry, Universiti Sains Islam, Malaysia (USIM) from April to July 2018. The demographic and clinical data were collected from the patients’ notes and included relevant information of patients such as age, gender and others. Full-coverage crowns were analysed and crown preparation assessments were done using specific criteria and standards. The descriptive data were measured in frequency and percentage for categorical variables and mean and standard deviation for continuous data. Results: A total of 31 patients fitted with 45 units of full-coverage crowns were analysed. The mean age of patients treated by fifth year dental students was 40.5 (±14.16) years. A 51% Porcelain Fused to Metal (PFM) crown provided to the patients. On the whole, UG undergoing the dentistry programme in the institution scored the lowest (51%) on proximal reduction and the highest (97.7%) on producing smooth and continuous preparation. Conclusion: Majority of the crowns prepared by students have acceptable preparation except in proximal reduction and cervical margin preparation that can be improved upon and emphasised further during the teaching and learning sessions.
Coronavirus Disease 2019 (COVID-19) is an acute infectious disease that causes global outbreaks. The COVID-19 outbreak has forced various sectors to change their approach and daily practice to new alternatives. Dental education is no exception to the effects of this pandemic, which has severely disrupted teaching, learning and clinical activities. The impact of this pandemic on dental education can be classified into different aspects, including academic, practical, research and clinical services. Teaching and learning activities have been transformed into distance learning methods. However, dental educators are still struggling with psychomotor components, including practical and clinical sessions, which are the main course components that are severely affected. This sharing of experience focuses on the effects of the pandemic on the delivery of dental education and the actions taken by the Faculty of Dentistry, Universiti Sains Islam Malaysia (USIM) to ensure continuous learning. The challenges faced by the faculty are overcome with careful planning and discussion through the establishment of specific committees related to various issues, such as online learning and clinical COVID-19 committees. The committees identify any issues, plan the strategies and monitor the implementation of the plan. All actions during the pandemic are closely monitored by managing the faculty and university to ensure implementation of organised and smooth work, good record keeping, and compliance with instructions and guidelines by the authority.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
