Assessment of knowledge, attitude, and practice of faculty and postgraduates toward Bisphenol A (BPA) exposure in dental care.

Bisphenol A (BPA) is commonly used in resin-based dental materials and is categorised as an endocrine-disrupting compound. This study aimed to evaluate the knowledge, attitudes, and practice toward the use of BPA among faculty members and postgraduate students. In this descriptive study, a validated self-administered questionnaire was used, and 204 dentists were included, with a response rate of 56.2%. The findings revealed that faculty members had significantly better knowledge (p=0.024) and practice (p=0.036) and more positive attitudes (p=0.024) toward BPA exposure. Regression analysis showed a significantly positive effect of attending a workshop/lecture or reading an article about BPA on the participants' total mean knowledge (p<0.001) and practice scores (p<0.001). Furthermore, faculty members showed a significantly more positive attitude (p<0.001) toward BPA exposure. These results emphasise the importance of increased awareness and education concerning BPA exposure to ensure optimal dental care.

A literature review of clinical efficiency, patient satisfaction, and future preference of Isolite and DryShield dental isolation systems among pediatric patients.

This review aims to summarize and analyze previous studies that evaluated the clinical efficiency, patient satisfaction, and future preference of Isolite System Isolation (ISI) and DryShield System Isolation (DSI) and compare them to other forms of isolation during dental treatment in children. Both authors independently searched engines using the keywords "Isolite", "Vacuum", "DryShield" and their combinations in March 2022. The inclusion criteria included peer-reviewed articles written in English and clinical trials that assessed the clinical efficiency, patient satisfaction, and future preference of ISI or DSI during dental treatment on healthy unaffected children and compared it to other isolation systems such as rubber dam and cotton roll. A total of five articles were included, and data were extracted by both authors independently and compiled into one single table.Five clinical trials were identified. The use of both ISI and DSI systems is associated with more noise, requires less chair time, is more comfortable, and is preferred by more children than rubber dam or cotton ball isolation.The review reports promising results in clinical efficiency, patient satisfaction, and future preference for both Isolite and DryShield isolation systems. Both systems require less chair time and were preferred by pediatric patients for future dental treatment when compared to both rubber dam and cotton roll isolation systems. Less fluid leaking and gagging reflex were reported when compared to cotton roll isolation. When compared to rubber dam isolation, they were associated with less discomfort.
