{1125201033{} {\*Riched20 10.0.22621}41 200 200 22 200 Cause: Carpal tunnel syndrome is caused by pressure on the median nerve in the wrist. This can result from repetitive hand movements, wrist anatomy, or health conditions like arthritis. Neutral Seated Position A neutral seated position involves sitting with your back straight, feet flat on the floor, and knees at a 90-degree angle. This helps prevent strain on the musculoskeletal system. Patients Head Position The patients head should be positioned so that the clinician can see the treatment area clearly without straining. Typically, the head is tilted slightly back and to the side. Common Positioning Errors Made by Clinicians Bending over the patient Raising shoulders Twisting the torso Not adjusting the patients chair properly Clock Position Refers to the position of the clinician relative to the patient, often described using a clock face. For example, 12 oclock is directly behind the patient. Standing Position When Debriding When standing to debride, maintain a neutral posture with feet shoulder-width apart, knees slightly bent, and avoid leaning forward excessively. 3 Parts of the Periodontal Instrument Handle: The part you hold. Shank: Connects the handle to the working end. Working-End: The part that performs the task, such as scaling. Modified Pen Grasp A way to hold instruments using the thumb, index, and middle fingers, providing control and precision. Proper Glove Fit Gloves should fit snugly without being too tight, allowing for dexterity and tactile sensitivity. Retraction, Indirect Illumination, Transillumination, Indirect Vision Retraction: Using a mirror or tool to move tissues aside. Indirect Illumination: Reflecting light onto an area. Transillumination: Shining light through tissues. Indirect Vision: Using a mirror to see areas not directly visible. Fulcrum A finger rest used to stabilize the hand during instrumentation. Tactile Sensitivity The ability to feel vibrations and textures through the instrument, crucial for detecting calculus. Balanced Periodontal Instrument An instrument where the working end is aligned with the handle, reducing strain. Simple vs Complex Shank Design Simple Shank: Straight, used for anterior teeth. Complex Shank: Bent, used for posterior teeth. Short vs Long Functional Shank Length Short Shank: For shallow pockets. Long Shank: For deep pockets. Parts of the Periodontium Includes the gingiva, periodontal ligament, cementum, and alveolar bone. How to Identify the Correct Working End The correct working end adapts to the tooth surface without causing trauma. Texturing of Instrument Handle (Knurling) Texturing on the handle provides a better grip. Parts of the Working End Face: The top surface. Back: The opposite side of the face. Lateral Surface: The sides. Cutting Edge: The sharp edge used for scaling. Double-Ended Instrument An instrument with a working end on both sides of the handle. Lower Shank (Terminal Shank) The part of the shank closest to the working end. Cross-Section of Instruments The shape of the instruments working end, which can be round or triangular. Assessment Instruments vs Calculus Removal Instruments Assessment Instruments: Explorer, probe. Calculus Removal Instruments: Curets, sickles. Mirror - Different Uses and Parts Uses: Retraction, indirect vision, illumination. Parts: Handle, shank, mirror head. Explorer Activation: Light grasp, exploratory strokes. Adaptation: Keep the tip in contact with the tooth. Uses: Detect calculus, caries. Correct Working End: Adapts to the tooth surface. Surfaces Towards and Away: Different techniques for anterior and posterior teeth. Probe Activation: Gentle pressure. Uses: Measure pocket depths. Calculate CAL: Add recession to pocket depth. Nabors Probe/Furcations Class I: Early involvement. Class II: Moderate involvement. Class III: Through-and-through involvement. Class IV: Visible through-and-through involvement. }
