NON-SURGICAL PERIODONTAL TREATMENT: CLINICAL AND MICROSCOPIC EVALUATION
Journal Title: Revista Científica do CRO-RJ / Rio de Janeiro Dental Journal - Year 2018, Vol 3, Issue 1
Abstract
Objective: To compare the effectiveness of two combined non-surgical periodontal therapies from an analysis of the treated tooth surface using optical microscopy (OM) and scanning electron microscopy (SEM). Methods: Thirty patients were selected with moderate to severe periodontal disease and indicating at least one piece for extraction due to poor prognosis. A clinical study with a split-mouth, randomized, double-blind design was performed. Two combined treatment modalities were compared: Cavitron Bobcat™+ completion with Gracey Curettes (G1); EMS™ + completion with Gracey curettes (G2). The treatment was performed until a smooth surface was obtained and no residual calculus was present, which was verified by a periodontal probe. The extracted pieces were analyzed by OM and SEM. Periodontal variables were: plaque index (PI), bleeding on probing (BP), probing pocket depth (PPD), clinical insertion level (CIL), gingival recession (GR) were observed before treatment, 3 and 6 months later. The operative time (OT) for each method was also analyzed. The results were compared by ANOVA followed by the Tukey test, setting the significance value at p<0.05. Results: PI, DP, PPD and CIL performed similarly in both groups. GR, determined in mm, was for G1 (0.31) and for G2 (0.46). OT, in minutes per tooth, was for G1 (3.21) and for G2 (3.12). Conclusion: Both treatment modalities favored the resolution of periodontal disease. Piezoelectric ultrasound combined with Gracey curettes produced greater gingival recessions. The surfaces analyzed by OM and SEM did not show statistically significant quantitative or qualitative variations.
