KNOWLEDGE, AWARENESS, AND PRACTICES REGARDING BIOMEDICAL WASTE MANAGEMENT AMONG UNDERGRADUATE DENTAL STUDENTS

Objective: The objective of this study was to assess the knowledge, awareness, and practices of dental students regarding biomedical waste (BMW)management.Methods: A self-administered structured questionnaire consisting of 16 questions on knowledge, awareness, and practices about BMW managementwas distributed among 100 students randomly belonging to 3rd year, final year and intern students of Saveetha Dental College, Saveetha University,Chennai. The data extracted were tabulated, statistically analyzed using SPSS version 20.0 and results obtained. The data were analyzed using ANOVAtest (all the results are calculated at 1% level of significance) and Post-hoc test.Results: Overall, 67% respondents were aware of the existing BMW management policy systems in India. 62% of students were aware about thecorrect color coding management system for hospital waste management that prevails in India. 86% of students knew about the dental wastecategories of materials used in dentistry. There was a statistically significant difference of knowledge levels among the 3rd year, final year students andthe interns. 100% practice discarding sharps in the puncture-proof containers. Only 27% of the respondents discarded the extracted tooth in a properway. Only 51% of them have attended previous training programs on dental waste management. There was also a statistically significant difference ofBMW disposal practices among the three groups.Conclusion: The majority of dental students in our study have good level of knowledge and awareness regarding BMW management in dental clinics.However, their practice toward BMW disposal was poor. Hence, the knowledge acquired must be put into practice. Intern students have the highestlevel of knowledge and practices toward dental waste disposal when compared to final year and 3rd year students. Hence, these findings imply thatproper training, continuing education programs, and short-term courses about BMW management, and infection control procedures are requiredto motivate the dental students and dental auxiliaries. The importance of training regarding BMW management must be emphasized as the lack ofproper and complete knowledge about BMW management impacts practices of appropriate waste disposal.

ABSTRACT Objective: The purpose of this study was to investigate compliance, awareness and practices of infection control procedures among senior dental students at the College of Dentistry, University of Sharjah, United Arab Emirates. Materials and Methods: The study comprised of 119 subjects of 4 th and 5 th year dental students. A questionnaire was developed with 25 open and closed-ended questions related to barrier techniques, vaccination status, infection control practices and awareness. This was distributed among the senior dental students and completed upon signing the consent form. Each questionnaire was coded to ensure the confidentiality of responses. Results: The questionnaire was distributed among 223 senior dental students at the University of Sharjah of which only 119 students (53%) responded. Compliance with the use of protective barriers was high with the exception of protective eye wear, utilized by a mere 27% of students. There was a significant difference between 4 th and 5 th year dental students′ attitudes (p < 0.05) regarding the treatment of patients with infectious diseases. Compared with 44.4% of the 5 th year students, 68.5% of the 4 th year students did not mind treating patients with infectious diseases. Owing to this, 61.9% of the 5 th year students suffered from non-sterile percutaneous and mucous membrane exposures compared with 44.6% of the 4 th year students (p < 0.05). Conclusions: Efforts are needed to improve attitudes, implement information and motivate students in the correct and routine use of infection control measures. With all infection control protocols already implemented in dental schools, the challenge remains on improving compliance with infection control recommendations.

OBJECTIVE: To evaluate in vitro the sealing ability of three materials used as cervical barrier for internal dental bleaching. METHODS: Thirty-three canines were selected, and after biomechanical root canal preparation, the canals were filled by lateral condensation technique. After the filling material setting reaction, the teeth were randomly divided into three groups of ten teeth each, according to the following materials for constructing the cervical barrier: X Temp LC; Vitro Fil; Coltosol. The control group consisted of three teeth, without placement of the cervical cap. Sodium perborate /distilled water associated with 2% Rhodamin B were used as bleaching substance. After placing the bleaching agent in the pulp chamber, access cavities were sealed with temporary cement IRM and samples were stored at 37 ° for 7 days. After this period, the samples were cleaved longitudinally, and leakage was evaluated by the visual method. The data were submitted to Pearson test with a 5% level of significance. RESULTS: No statistically significant difference was found between the study groups, however, the largest number of specimens with a lower degree of leakage were found in the Coltosol group. CONCLUSION: All the materials evaluated for making the cervical cap allowed some level of leakage.

Treatment And Disposal

ABSTRACT Various national and international agencies have shown their concern towards proper handling, treatment and disposal of biomedical waste, as they may cause serious infectious diseases like hepatitis, tuberculosis and HIV/AIDS. Most of the hospitals do not have effective disposal system leading to complex problem of hygiene and sanitation in hospitals. The use of disposable items has reduced the rate of infection but at the same time has increased the volume of the waste which needs to be disposed properly. Effective waste disposal can be achieved only by considering the various components of the waste management system and this should be made an integral part of hospital planning and designing.

Posterior Restorations

Background: The most common restorative materials used in dentistry are amalgam and composite. Amalgam is a controversial material owing to its mercury toxicity. With recent advances in the properties of composite materials, there has been a shift towards its use. Objectives: The aim of this study was to understand the perceptions of undergraduate dental students in a northern Saudi Arabian dental school about the choice of restorative materials for restoring posterior teeth. Methodology: The study included undergraduate students studying in 4th and 5th year dental program in College of Dentistry, Jouf University. A four-item questionnaire with 18 close-ended questions was developed by the investigators, which were hand delivered to all the students. Data analysis is presented through tables and descriptive methods. Results: A total of 98 (out of 131) undergraduate students participated in this study. Overall, the students reported a significantly strong influence of the type of restorative materials in relation to the cavity size and margin of the restorations along with the esthetics factor(p<0.05). There was slight influence on the student’s choice because of the instructor's influence, whereas the students felt they were knowledgeable and had appropriate training to use either amalgam or composite. The study also found that patient’s preference had a strong influence on choosing composite material. The students were mostly not influenced while choosing the material as far as the safety of it was concerned. However, the patient’s influence was slight when it came to the choice of the material. A significant difference was noted among the students when it came to pregnancy-related safety concerns where the choice of material was not influenced by either amalgam or composite (p=.002). Conclusion: The undergraduate dental students at College of Dentistry, Jouf University are comfortable in using both amalgam and composite as a posterior restorative material. They are knowledgeable about both the materials and are adequately trained to use either one.
