The aim of the study was to evaluate the efficacy of a polarized, polychromatic, non-coherent light (Bioptron), in addition to full mouth scaling and root planing, in chronic periodontitis. Forty adult patients affected by chronic periodontitis were enrolled in the study and were randomly divided into two groups. The control group received only full mouth scaling and root planing (FMSRP), while in the test group, Bioptron light treatment was added to FMSRP. The Full Mouth Plaque Score (FMPS), Full Mouth Bleeding Score (FMBS), Gingival Index (GI) and Probing Pockets Depth (PPD) were recorded in both groups at the first examination, after 1 month (T1) and after 3 months (T2). Both groups showed a significant reduction of FMPS at T1 and T2 (p less than 0.05). Both groups showed a significant reduction of FMBS at T1 and T2 (p less than 0.05), but a higher improvement (p less than 0.05) was recorded in the study group at T1. Study group GI was significantly reduced at T2 (p less than 0.05), differently from the control group (p>0.05). PPD showed a reduction in both groups with no statistically significant differences (p>0.05) between them. Polarized, polychromatic non-coherent light seems to be an effective additional therapy in the management of adult chronic periodontitis, reducing inflammatory clinical indexes.
