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) ≤ 3 mm, 8 sites
with PD > 3 mm and < 5 mm, and 6 sites with PD ≥ 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 ≥ 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
≥ 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 ≥ 5 mm were
reduced to values less than 3 mm. Conclusion: Irradiation of deep pockets with highpower 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.
