Dentistry has been greatly benefitted from the advances in optical technology such as magnification loupes and operating microscopes.[1] Though each of them have their own merits and demerits, they help in improving precision required beyond unaided vision. Magnification is useful at any age for a dentist to perform precisely restorative and endodontic procedures. Magnification loupes are used in dentistry where increased visual performance is needed. Increased magnification and improved illumination of the operating field has many benefits for the operator, especially CX-5461 manufacturer in endodontics.[2] The treatment quality improves through the usage of magnifying devices. The ability to work with a high level of accuracy and improved control reduces treatment time and reduces operator fatigue. According to various data, it has been found that every dental professional is at a potential risk for developing Sitaxentan occupational musculoskeletal problems including the vision and posture in which the clinician sits. Slight modification in posture and vision through the usage of magnifying aids can improve the work efficiency of the clinician.[3] Achromatic compound magnification loupes increase the size from ��2 to ��5, though magnification of ��2.5 to ��4 is generally used for restorative procedures.[4] The interest and use of loupes among dental practitioners and students appears to be growing.[5] Thus, the use of appropriate visual enhancement should be considered for all dental professionals to make the practice of dentistry more precise, easy, and more enjoyable; and thereby reducing the risk of musculoskeletal problems. The objective of this study was Forskolin ic50 to evaluate clinical performance during tooth preparations for Class II cavities using magnification loupes among dental interns and final year BDS students in the preclinical laboratory. MATERIALS AND METHODS Forty Nos of Typhodont teeth #36 (20 Nos) and #46 (20 Nos) (Frasaco-USA) mounted on a lower acrylic jaw base of phantom head were prepared for a conservative mesio-occlusal (MO) Class II cavity design using micromotor, mouth mirror, explorer and periodontal probe in preclinical laboratory of conservative dentistry, and endodontics. The sample size comprised of dental interns and final year BDS students is divided equally into two groups, aged between 22 and 24 years. The study groups were asked to prepare two teeth each #36 was prepared using magnifying loupes (Heine [Germany], HR ��2.5, 420 mm/16��) while #46 was prepared without the loupes. The subjects were chosen having a normal vision or eye power
