ABSTRACT
Nanotechnology is widely used in day to day life including its use in medicine. Using nanotechnology it is easy to analyse the atoms , chemical bonds and molecules present between various compounds. Use of nanoparticles in the field of dentistry is called nano dentistry. Chemical, physical and biological aspects of nanoparticles should be taken into account while choosing nanoparticles for the use in the field of nano dentistry. Nanoparticles are used in innovations of dentistry. Nano materials can be used for preventing and curing oral diseases such as oral cancer and to maintain oral health care. This study aims at evaluating knowledge and awareness of nanoparticles incorporated in dental materials among undergraduate dental students. A questionnaire with a set of 9 questions to assess the students knowledge and awareness about nanoparticles incorporation in dental materials. The sample size of 99 participants of dental students of Saveetha Dental College were selected by a simple random sampling method. The participants were asked to fill the questionnaire in an online site called survey planet. The results were collected and statistically analysed. Chi square test was done and it was found that 71% of the participants were aware about the use of nanoparticles in dental materials, even though it is statistically not significant (p value- 0.436), 73% of respondents were aware about nanoparticle incorporation in impression materials with p value 0.449 (not significant) and 72% were aware about use of nanomaterials in titanium implants(p value-0.340). Within the limitations of the study, it can be observed that the undergraduate students at the Faculty of Dentistry of Saveetha were well aware about the use of nanoparticles in dental materials
ABSTRACT
The aim of this study was to evaluate the awareness and knowledge on the use of Botox injections in facial aesthetics among undergraduate dental students. Botulinum toxin is considered as a quick and effective non-surgical solution for enhancing physical appearance. Botox is considered as the best choice, as it is affordable and less radical than surgery. It is derived from gram-positive spore forming, clostridium botulinum. A questionnaire was developed to evaluate the awareness of dentists towards using botulinum toxins in facial aesthetics. The survey was conducted online via survey planet. There were about 103 study population, participated in this study. Data is collected using an online survey planet link and statistically analysed. 95.1% of participants reported that they have general knowledge on the Botox (95.1%). 66 % of respondents agreed that clostridium botulinum bacterium is the source of Botox. 24.51% of respondents stated that Botox was commonly used for wrinkle reduction and 96.1% were aware of the toxicity effect of Botox when it is administered in a high dosage. Association between response of the participants and knowledge on Botox was found to be statistically significant (p<0.05). According to our study, the majority of students showed an acceptable level of knowledge and awareness on Botox and its use in facial aesthetics
ABSTRACT
Beta-lactam antibiotic is the most common antibiotic prescribed by dental students. However, the actual knowledge on beta lactam is important as antimicrobial resistance is currently an alarming and growing phenomenon and in turn becoming a public health challenge. A survey was conducted to assess the knowledge and awareness of beta-lactam antibiotics prescriptions among dental students in their third years, final years and interns. A total of 145 responses were obtained and the results were analyzed using the SPSS statistical software.Based on their knowledge on beta-lactam antibiotics, 59.3% of the participants knew exactly the mechanisms of action of beta-lactam antibiotic which was by interfering with the synthesis of the bacterial cell wall. In the case of penicillin allergy, 40% ofthe participants chose erythromycin as the alternative for penicillin allergy. 84% of the participants were aware that the combination of amoxicillin with clavulanic acid may increase its effectiveness. Meanwhile, 98% of the participants were aware that amoxicillin is the drug of choice for bacterial endocarditis prophylaxis. 72% of the participants were aware that most beta-lactam antibiotics are considered safe for pregnant and lactating women which was statistically significant (p<0.05). In conclusion, the students had quite a good knowledge and awareness regarding the prescription of beta-lactam antibiotics since they have been practicing under guidance from the practitioner in the college
