    Abstract:
    BACKGROUND: This study compares diamond burs and curettes by clinical, microbiological, biochemical and 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 the other two quadrants were treated with curettes. Clinical periodontal measurements were recorded at baseline and then 1, 3 and 6 months after completion of non-surgical periodontal treatment. Subgingival plaque and 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 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) and ratio of each bacterium to the total bacterial count at baseline and 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 and loss of tooth substance indices but roughness index values were better for curettes. CONCLUSIONS: Diamond burs provide findings comparable with curettes in root planing.
