Diamond burs versus curettes in root planing: A randomized clinical trial

Abstract

Aim

This study compares diamond burs and curettes by clinical, microbiological, biochemical, scanning electron microscopic parameters and treatment time data in the non-surgical periodontal treatment of patients with chronic periodontitis.

Methods

Two quadrants of each of the 12 patients received root planing with diamond burs whereas other 2 quadrants were treated with curettes. Clinical periodontal measurements were recorded at baseline and then 1, 3, 6 months after completion of non-surgical periodontal treatment. Subgingival plaque, gingival crevicular fluid samples were obtained at baseline and 1-month control. Twenty-one hopeless teeth received root planing with diamond burs or curettes or no treatment at all and then extracted for microscopic evaluations.

Results

Clinical periodontal parameters improved similarly with both treatment modalities. Microbiological analyses revealed similar findings for the bacterial load (16S gene copy numbers), ratio of each bacterium to the total bacterial count at baseline, 1-month control. Cytokine levels in the gingival crevicular fluid samples exhibited differences between the two treatments. Scanning electron microscopic analyses indicated that diamond burs were better in terms of calculus removal, loss of tooth substance indices, but roughness index values were better for curettes.

Conclusion

As a conclusion, diamond burs provide findings comparable with curettes in root planing.
