This review paper examines the chemical and mechanical properties of natural fiber reinforced polymer bonded composites and the processing techniques are compared for the reinforced composite materials. The chemical and mechanical properties of the different natural fibers composites were compared. Present days natural fibers are attracting many scholars and researchers due to its cost and largely available in nature also processing of these fibers is not hard in comparison to the conventional fiber's production. Also, Environmental awareness and a growing concern with the greenhouse effect have triggered the construction, automotive, and packing industries to watch out for ecofriendly materials that can replace conventional synthetic polymeric fiber's. Natural fibers seem to be a good alternate because they are readily available in fibrous form and can be extracted from herb leaves at very low costs. By these reasons the natural fibers are trusted over the regular fibers.

Aim: The purpose of this cross sectional study was to understand and evaluate local practioner`s knowledge on dental bur selection, its usage, sterilization procedures undertaken and the method of disposal of dental burs in restorative procedures. Materials and Methods:A questionnaires proforma was prepared with each question having 4 answers. A total of 20 questions were framed and were sub-divided in to 3 categories namely selection, usage sterilization and disposal. These questionnairess were sent to all the local practioner`s by mail and to ensure a high response rate as they were followed up by telephone calls. The results were analyzed statistically and were represented in the form of percentage.
