The Effectiveness of the Titan‐S Sonic Sealer Versus Curettes in the Removal of Subgingival Calculus

“…Complete calculus removal following periodontal instrumentation is rare 27 . Similarly to other studies, 4,27,28 we found that 22.3% of the total surfaces evaluated were free of calculus.…”

“…Studies have demonstrated that it is not. [23][24][25][26][27][28][29][30] This study agrees with these findings. There was residual calculus remaining after instrumentation with no significant difference between the two curets.…”

The Effectiveness of Scaling and Root Planing With Curets Designed for Deep Pockets

This study evaluates the effectiveness of subgingival scaling and root planing with longer shank, thinner blade, rigid curets compared to the standard rigid Gracey curet. A total of 35 non-molar teeth from 7 patients provided 140 root surfaces for evaluation; 52 root surfaces were instrumented with the rigid longer shank curets; 52 with the standard rigid Gracey curets; and 36 provided untreated controls. A bilateral matched design was utilized where contralateral teeth in the same arch were instrumented. Instrumentation was standardized at 15 minutes per tooth. Both scaled and unscaled teeth were extracted immediately after the experimental procedures. They were viewed under a stereomicroscope with a 0.10 mm grid to assess the percent of surface covered by calculus and unaltered cementum. The curet efficiency was also evaluated. The results indicated a significant treatment effect compared to the controls in relation to the percentage of residual calculus and curet efficiency. However, there was no significant difference between the rigid longer shank and standard rigid Gracey curets. There was a difference noted when tooth surfaces were evaluated. Mesial tooth surfaces had the least remaining calculus and demonstrated the best curet efficiency.

“…This could account for the low percentage (3.9%) of molars extracted during active treatment. Because the mean PD (6.7 mm) exceeded the depth of effective scaling and root planing (SRP) (5 mm), surgery was done on most molars 45,46 with emphasis on thorough SRP. Conservative osseous surgery was done to remove thickened bone and to enhance flap adaptation.…”

Background This retrospective study evaluated and assigned scores to six prognostic factors and derived a quantitative scoring system used to determine the periodontal prognosis on molar teeth. Methods Data were gathered on 816 molars in 102 patients with moderate to severe periodontitis. The six factors evaluated, age, probing depth, mobility, furcation involvement, smoking, and molar type, were assigned a numerical score based on statistical analysis. The sum of the scores for all factors was used to determine the prognosis score for each molar. Only patients with all first and second molars at the initial examination qualified for the study. All patients were a minimum of 15 years post treatment. Results The post treatment time ranged from 15 to 40 years and averaged 24 years. When the study was completed, 639 molars survived (78%), and of those surviving molars, 566 survived in health (89%). In molars with lower scores (1,2,and 3) the 15-year survival rates ranged from 99% to 96%. For scores 4, 5, 6 the 15 year survival rates ranged was 95% to 90% and for molars with scores of 7, 8, 9, and 10 the survival rates ranged from 86% to 67%. Conclusions Our results indicate that the periodontal prognosis on molars diagnosed with moderate to severe periodontitis can be calculated using an evidence-based scoring system.
