Eficácia do laser de diodo de alta potência como coadjuvante à instrumentação mecânica de bolsa profunda em paciente com periodontite estádio III, grau C e generalizada.

Abstract

Periodontitis is an inflammatory clinical condition caused by a dysbiotic biofilm that results in progressive destruction of the periodontal attachment and can lead to tooth loss if left untreated. The objective of this study was to evaluate the clinical efficacy of high-power diode laser as an adjunct to mechanical instrumentation in deep pockets of a patient with generalized Stage III, Grade C periodontitis. A total of 126 sites were examined, including 112 sites with probing depth (PD) f 3 mm, 8 sites with PD > 3 mm and < 5 mm, and 6 sites with PD g 5 mm. Parameters of probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were evaluated at baseline, 3 months, and 6 months after basic therapy. All patients received non-surgical periodontal treatment, including scaling and root planing (SRP) and coronal polishing. Deep periodontal pockets with PD g 5 mm received adjunctive therapy with high-power diode laser, using a wavelength of 808 ± 10 nm, power of 1.5 W, continuous mode, and delivered through a 400 μm diameter optical fiber device. Results: There was a significant improvement in periodontal parameters of probing depth (p < 0.001), clinical attachment loss (p < 0.001), and bleeding on probing (p < 0.001) in all treated sites. Similar results were observed in sites with PD g 5 mm, with a statistically significant reduction in probing depth (p = 0.006), clinical attachment loss (p = 0.006), and bleeding on probing (p = 0.022) before and after treatment. After 6 months, all deep periodontal pockets with PD g 5 mm were reduced to values less than 3 mm. Conclusion: Irradiation of deep pockets with high- power diode laser proved to be effective as an adjunctive therapy to scaling and root planing in a patient with generalized Stage III, Grade C periodontitis.
