Solid handles: reduce tactile transfer and increase fatigue Hollow handles: increase tactile transfer and minimize fatigue
Handles with small diameter, heavy solid metal core and smooth, flat texture are generally avoided. Hollow handles are more widely used because of better tactile perception and minimized muscle fatigue. The weight of the handle is determined by its diameter and its core (solid or hollow). Presently, they are available in various weights, diameters, and textures. The handle of the instrument is used for grasping the instrument. Parts of an instrumentįollowing is the detailed description of these three parts of the instruments, Handle: Double-ended instruments with working ends that are mirror images of each other have paired working-ends while instruments with two dissimilar working ends have unpaired working ends. The instrument may be single-ended or double-ended. The working end does the work of the instrument. Shank connects the handle to the working end and allows adaptation of the working end on the tooth surface. Parts of an instrumentĪn instrument can be broadly divided into three parts: handle, shank, and working end. The following discussion is focused on various aspects of periodontal instrument designs and their specific uses. A thorough knowledge of instruments is mandatory for their appropriate usage. Presently, there is a large range of instruments available for the removal of supra and subgingival calculus, including ultrasonic devices, sickles, hoes, chisels and curettes. Periodontal instruments have been designed specifically to achieve this goal. Removal of these local factors to obtain a clean root surface is mandatory to achieve periodontal health. Local factors like plaque and calculus are the major factors for periodontal disease progression. The re-establishment and maintenance of periodontal health are the main objectives of periodontal treatment. Periobasics Clinical Periodontology, Recent Posts Introduction to periodontal instruments
