Prosthodontics practice involves contact with restorative materials, auxiliary dental materials which are broadly of different composition. The leakage and transfer of the potent allergic components from these materials is the cause of hypersensitive reactions to patients, dental professionals and the lab technicians. The biological side-effects of the materials that are in dental practice are rare. All artificial materials release substances in the oral environment which are potent allergens that might cause side effects and adverse reactions. The current study gives a statically about the dental professional knowledge and also makes the aware of toxic biological side effects of these materials, also make them aware of the reporting of the cases. A cross sectional survey was conducted among 100 dental professionals about the Toxic Biological effects associated with materials used in prosthodontics. Questionnaires with 20 close ended questions were circulated among people. Results obtained analyzed using SPSS software. In this Study, almost 80% of them were aware that some components of the dental materials might cause a hypersensitivity reaction. 57% of the participants have not experienced any allergic resin, latex, gloves etc. The prevalence of allergic reaction among Dental staff is low and most reported are due to latex, acrylate & formaldehyde. The present study shows that there is a lack of knowledge on the toxic biological effects of dental material used in prosthodontics. [ABSTRACT FROM AUTHOR]

PEEK stands for Poly Ether Ether Ketone.. It is a semi crystalline polycyclic aromatic linear polymer. It is a white and a radiolucent material that is rigid in nature. PEEK is the latest invention in the field of dentistry. It is known that this material can prove as a substitute for the existing dental materials. It is claimed that this has better properties than other materials. PEEK has been the center of attention for a lot of scientists looking for better alternatives to the existing materials. Various researches and reviews have been carried out in detail to study this material. The role of Poly Ether Ether Ketone in dentistry by itself has been a majorly studied topic. A literature review was carried out using a systematic search strategy and articles were found using keywords. Literature was taken from databases like PubMed and Google Scholar. Articles that discussed the properties of PEEK and its applications were included. Other articles which had data regarding the structure and its advantages were also included. This review summarized the properties of Poly Ether Ether Ketone. Its structure, and other applications in different dental materials were also discussed in detail. [ABSTRACT FROM AUTHOR]
