Abstract		Residual subgingival calculus (RSC) was studied in 23 patients undergoing flap surgery following nonsurgical treatment of periodontal disease. A total of 51 modified Widman operations (1-6 in each patient) were performed, and 205 teeth with 1055 surfaces were evaluated. Pockets of 1-3 mm were found on 64%, 4-6 mm on 30 %, and >=7 mm on 6 % of the treated surfaces. RSC deposits were present on 191 surfaces (18%). The surfaces carrying the deposits had an average pocket depth of 4.77 mm and an average clinical attachment level of 5.4 mm apical to the cementoenamel junction. Fifty-one per cent showed no bleeding on probing, 41 % showed bleeding, and 8% exhibited suppuration from the periodontal pocket. Over a third of the deposits (37 %) were thin and level with the root surface, in the shape of a dot or flake. The remaining 63 % were thicker, extending above the root surface in the form of a line or spot. Thin deposits were mostly found in shallow periodontal pockets, while deep pockets contained thicker deposits. The association between pocket depth and deposit thickness was statistically significant (p = 0.02). Thirty-five per cent of the RSC deposits were found on teeth with pocket depth of 1-3 mm, 50% on teeth with pocket depth of 4-6 mm, and 15% on teeth with pocket depth of >=7 mm. RSC on the proximal surfaces of teeth with deep periodontal pockets is an indication for periodontal surgery, which allows visual inspection and thorough scaling and planing ot the exposed root.
