Comparison between scaling-root-planing (SRP) and SRP/photodynamic therapy: six-month study

Area of Science:

• Periodontology
• Dental Therapeutics
• Photomedicine

Background:

• Chronic periodontal disease affects a significant portion of the adult population.
• Periodontal disease management often involves mechanical therapies like scaling and root planing (SRP).
• Exploring adjunctive therapies to enhance SRP efficacy is crucial for improved patient outcomes.

Purpose of the Study:

• To evaluate the additional efficacy of photodynamic therapy (PDT) when used alongside scaling and root planing (SRP).
• To assess the impact of SRP combined with PDT on clinical parameters in patients with chronic periodontal disease.

Main Methods:

• A clinical study involving 22 patients with chronic periodontal disease.
• Patients received either SRP alone or SRP combined with PDT (Periowave).
• Clinical parameters including probing depth and clinical attachment loss were measured at baseline and at one, three, and six months post-therapy.

Main Results:

• Both SRP and SRP/PDT treatments led to a reduction in bleeding on probing.
• A statistically significant greater reduction in probing depth was observed with the combination of SRP and PDT after six months (p = 0.007).
• Improvements in clinical attachment loss were noted for both treatment groups over the six-month period.

Conclusions:

• Scaling and root planing (SRP) in conjunction with photodynamic therapy (PDT) demonstrates effectiveness.
• PDT serves as a suitable adjuvant therapy for mechanical conditioning of periodontal pockets.
• The combined approach offers a promising strategy for managing chronic periodontal diseases.
