Hemodynamic periodontal changes in the treatment of chronic generalized periodontitis using polarized polychromatic light

Background: Ineffective treatment of inflammatory periodontal diseases is a significant medical and social issue. Previous research have shown that improved vascular response and local immunity activation are crucial for the treatment of periodontal diseases. This can be accomplished using polarized polychromatic light. However, the effect of polarized polychromatic light on microhemocirculation in periodontal tissues is poorly understood.

Aim: To assess microhemodynamic changes in periodontal tissues in the treatment of mild chronic generalized periodontitis using polarized polychromatic light.

Materials and Methods: A complex dental examination and treatment were performed in 70 patients (32 males and 38 females) with active chronic generalized periodontitis aged 20 to 59 years. The study had two groups (35 subjects each) based on treatment approaches. Group 1 received professional oral care and a course of antimicrobial therapy using Dentamet dental gel. Group 2 received antimicrobial therapy in combination with polarized polychromatic light therapy (wavelength 480–3,400 nm, power 40 mW/cm², flux density 2.4 J/cm² per minute, polarization 95%). Laser Doppler flowmetry was used to assess hemodynamics before treatment, as well as 3, 6, and 12 months after treatment.

Results: Group 1 demonstrated an improvement in microcirculation parameters for up to 3 months (p=0.0027). In group 2, an improvement was observed for up to one year (p=0.0455).

Conclusion: Polarized polychromatic light therapy in mild chronic generalized periodontitis improves microhemocirculation in periodontal tissues, increasing the efficacy of drug therapy.
