How does scaling and root planing affect alveolar bone density?

Methods: Thirteen subjects with a total of 39 sites that presented with >3 mm of vertical bone loss were included. Radiographs were taken prior to treatment and were repeated 6 months following scaling and root planing.  Results: Digital subtraction radiography revealed an increase in radiographic density in 101 of the 117 test regions (83.3%). A significant increase in bone density was seen in probing depths >5 mm compared to those <5 mm in depth.  Conclusions:  Scaling and root planing of diseased periodontal pockets can significantly increase radiographic alveolar bone density  For more information please refer to:  Journal of PeriodontologyVolume 79,...

Amoxicillin and Metronidazole as an Adjunct to Full-Mouth Scaling?

Methods: Fifty-one patients received full-mouth periodontal debridement, performed within 48 hours. Twenty-five subjects received metronidazole, 500 mg, and amoxicillin, 375 mg, three times a day for 7 days; 26 subjects received a placebo.  Results: Mean probing depth decreased from 4.3 ± 0.4 mm to 3.0 ± 0.2 mm in the test group and from 4.4 ± 0.4 mm to 3.1 ± 0.3 mm in the control group. Test subjects had a significantly lower mean number of persisting pockets >4 mm and bleeding on probing that required further treatment.  Conclusions: Systemic metronidazole and amoxicillin significantly improved the 6-month clinical outcomes of...

Chlorhexidine Chips as an Adjunct to Scaling and Root Planing?

Methods: Twenty-six subjects with probing depth ≥5 mm and bleeding on probing participated in a split-mouth trial. At baseline, the patients received full-mouth scaling and root planing followed by placement of chlorhexidine chips.  Test sites still ≥5 mm deep at 3 and 6 months were retreated with another chlorhexidine chip. Results: Improvements of bleeding scores, probing depths and clinical attachment levels were observed for both test and control sites at 6 weeks compared to baseline. No differences in improvements were found comparing test and control sites.  Conclusions: This study did not observe any significant adjunctive effect of subgingival placement of...

How effective is subgingival scaling and root planing in calculus removal?

Methods: A total of 119 teeth in 25 patients were selected; 62 were scaled and 57 were used as controls. The levels of the gingival margin were marked on the teeth to locate supra and subgingival calculus. Both scaled and unsealed teeth were viewed under a stereomicroscope.  Results: There was a a high correlation between percent of residual calculus and pocket depth. Pockets less than 3 mm were the easiest sites for scaling and root planing.  Conclusion: Pocket depths between 3 to 5 mm were more difficult to scale.  Pockets deeper than 5 mm were the most difficult. Tooth type did...

How much root substance is removed by scaling and root planing?

Methods: Forty extracted teeth with loss of connective tissue attachment into the middle third of the roots were washed and embedded in plaster. A total of 40 working scaling strokes were applied. Low forces were used in 30 teeth and high forces in 10 teeth.  Results: Mean cumulative loss of root substance across 40 strokes was 148.7 microns at low forces, and 343.3 microns at high forces. Substance removal per stroke during strokes 1 to 5 was 6.8 microns using low forces and 20.6 microns using high forces.  Conclusions: High forces remove more root substance. Loss of root substance per...
