This document discusses different types of curettes used for instrumentation and root planing. It provides details on universal curettes that can be used in most areas of the dentition, as well as area specific curettes like Gracey curettes that target specific tooth surfaces. Gracey curettes are considered the best instruments for subgingival scaling and root planing due to their offset, curved blades that can access precise areas. Other curette types discussed include extended shank, mini-bladed, micro-mini, and Gracey curvettes, each with unique characteristics that make them suitable for different root planing applications.
Instrumentation for scaling and root planing
- 2. GROUP MEMBERS: M.Zain Perah Ushna Nadeem Ramsha Akhtar Zaira Batool Naila Adeel Priha Niaz
- 3. INTRODUCTION: SCALING: scaling is a clinical procedure by which calculus is removed from tooth surface
- 4. ROOT PLANING It is also a clinical procedure by which small deposits of calculus is removed and cementum and dentin are softened to make the root surface smooth
- 39. CURETTES
- 40. CURETTES Uses: 1.Removing deep subgingival calculus 2. Root planing 3. Removing soft tissue lining the periodontal pocket
- 41. CURETTES Characterstics: 1. Two working ends 2. Each working end has a curved blade and a rounded toe. 3. Cutting edges on both sides of the blade
- 43. CURETTES Types of Curettes: 1. Universal curettes 2. Area specific curettes
- 44. CURETTES Universal Curettes: 1. May be inserted in most areas of the dentition. 2. Blade curved in one direction… head to toe 3. Blade… 90 degrees to the lower shank.
- 46. CURETTES Area specific curettes: 1.Gracey curettes 2. Extended shank curettes 3. mini-bladed curettes 4. Micro-mini gracey curettes 5. Gracey curvettes 6. Langer and mini-langer curettes
- 47. Curettes Gracey Curettes: . Best instruments for subgingival scaling and root planing . Area-specific curettes.
- 48. Sets of Gracey curettes Area specific use 1-2 and 3-4 5-6 7-8 and 9-10 11-12 12-13 Anterior teeth Anterior and premolar Posterior… facial and lingual Posterior… mesial Posterior… distal Curettes
- 50. CURETTES Characterstics of Gracey: 1. Blade… 60 to 70 degrees to the shank (offset). 2. Blade curves…. 2 directions… upward and sideward. 3. Used with a pull stroke
- 52. Characterstic of gracey curette Utilization . 60 to 70 degrees angled from the lower shank The unique angulation allows the blade to be inserted in precise position CURETTES
- 53. Curettes Extended shank curettes: . Modification of gracey curettes . 3mm longer shank. . Thinned blade . #9-10 curettes not available
- 55. Characteristics of extended shank curettes Utilization . 3mm longer shank than gracey . Thinned blade . Extension into the deeper pockets . Smoother insertion in the pocket CURETTES
- 56. CURETTES Mini-bladed curettes: . Modification of extended shank curettes . Blade… half the length of gracey curettes
- 57. Characterstic of mini- bladed curette Utilization . Blade… half the length of gracey curettes Easier insertion and adaptation in deep narrow pockets . CURETTES
- 58. Curettes Micro-mini gracey curettes: . Smallest of all curettes . 20% thinner and smaller than the mini-bladed
- 60. Curettes Gracey curvettes: . Blade length… 50% shorter than gracey. . Blade is curved slightly upward.
- 62. Characterstic of Gracey curvettes Utilization . Blade is curved slightly upward . Curvature allows… close adaptation to the tooth surface than any other curettes CURETTES
