This study is aimed to review the applications of Polyether Ether Ketone (PEEK) in dentistry. The increased demand for aesthetics, legislation in some developed countries, few drawbacks with existing materials and clinicians shifting their paradigms towards metal free restorations led space for the metal-free restorations in today’s dental practice. An electronic literature search was conducted through Medline via PubMed, Wiley Online library, EBSCOhost, Science Direct, as well as the Google Scholar between January 2010 and March 2018 using the keywords: PEEK, modified PEEK, PEEK and Dental, advantages of PEEK, applications of PEEK in dentistry and PEEK Implants. A total of 103 articles were found in the literature search and out of these, 18 were not related to our study and hence were excluded. Finally, 85 articles were found to be relevant. PEEK has been explained for a number of applications in dental practice. The literature showed that the PEEK material has superior mechanical properties with different uses in various specialties of dentistry.

Introduction: The use of antibiotics in recent years has become more aggressive and more common. The inappropriate use, to be more precise, the abuse of these prescriptions, is the root cause for increasing bacterial resistance and adverse outcomes. Antisepsis can be suggested as an appropriate alternative to antibiotics, to control the increasing antibiotic resistance among individuals. Objective: The objective of this study was to compare the awareness of antibiotic prescription and resistance among BDS and MDS practitioners and students. Materials and Methods: A total of 361 dental professionals were included in this study. Each of them was given a questionnaire containing questions pertaining to antibiotic prescription and awareness. Results: Most of the participants prescribed antibiotics as pre and post treatment management of all the oral diseases during their routine interaction with the patients. Overprescription of antibiotics, amoxicillin being the most common, was significantly more among the BDS practitioners than the MDS practitioners. BDS practitioners (78%) preferred a 3-day antibiotic prescription whereas MDS practitioners (80%) prescribed a 5-day course, which was statistically significant. Mindfulness with respect to antimicrobial prophylaxis and antibiotic resistance was observed to be satisfactory in both the groups. However, there was a general absence of mindfulness with respect to the rules for antibiotic prescription recommendations in both the groups. Conclusion: Antibiotic prescription should be given with care to prevent its resistance, an upcoming iatrogenic health hazard.
