Periodontitis is one of the most common inflammatory diseases of the oral cavity, accompanied by the destruction of supporting tissues of the teeth. Modern treatment methods are aimed not only at eliminating inflammation but also at restoring periodontal structure. This study investigated the effectiveness of the combined use of hyaluronic acid and photodynamic therapy in the treatment of moderate chronic generalized periodontitis. A clinical observation of 60 patients was conducted, divided into a control and study group. The study group received a combination of standard treatment with hyaluronic acid applications and photodynamic laser therapy (λ = 660 nm). The results showed a significant improvement in clinical and microbiological parameters in patients in the study group. The combined method demonstrated anti-inflammatory, regenerative, and antimicrobial effects, ensuring long-term disease remission.
