This high-yield revision note on Scaling & Root Planing: Instruments, Technique & Healing covers everything examiners typically test under Periodontology — structured as quick-reference tables, clinical correlations, mnemonics and previous-year-style high-yield points. It's built for last-mile revision before NEET MDS, INI-CET MDS and INBDE, so you can scan it in minutes instead of re-reading a whole textbook chapter.
| Aspect | Detail |
|---|---|
| Scaling | Removal of supragingival and subgingival plaque/calculus from the tooth surface; does not intentionally remove cementum |
| Root planing | Removal of residual embedded calculus and necrotic/contaminated cementum to produce a smooth, hard root surface |
| Hand instruments | Sickle scalers (supragingival use); Curettes - Universal (e.g. Columbia, Barnhart - two cutting edges, usable in multiple areas) vs Gracey curettes (area-specific, single cutting edge, blade offset 60-70° to the shank) |
| Gracey curette area assignment | 1-2, 3-4: anteriors; 5-6: anteriors + premolars; 7-8, 9-10: posterior facial/lingual surfaces; 11-12: posterior mesial surfaces; 13-14: posterior distal surfaces |
| Ultrasonic/sonic scalers | Magnetostrictive and piezoelectric types; useful for gross calculus removal and biofilm disruption |
| Healing after conventional SRP | Predominantly via formation of a LONG JUNCTIONAL EPITHELIUM (not true new connective tissue attachment/regeneration) in most cases |
