ASSESSMENT OF LASER AND ANTIOXIDANT THERAPY EFFICACY IN TREATMENT OF CHRONIC GENERALIZED PERIODONTITIS.

Chronic generalized parodontitis is one of the most prevalent disorders among diseases of oral cavity, making the search for optimal treatment modalities of this disorder one of the mostressing matters to this day.  The purpose of this study was to assess outcomes of conventional therapy and secondary prevention of chronic generalized parodontitis with in combination with use of laser therapy and antioxidant drug treatment.   The study is presented as a joint multi-site investigation conducted by the group of authors from St. Petersburg and Saransk medical teaching and clinical institutions. The aim of the study was to improve the treatment and secondary prevention of chronic generalized parodontitis based on a pathogenetically substantiated scheme of laser and antioxidant therapy.   The total of 98 patients (31 male and 67 female) aged 30-50 years) with the 3 to 10 year history of moderate chronic generalized parodontitis were selected for the prospective study.  All patients were approximately equally divided into three groups according to the received treatment regimens: conventional treatment, laser therapy, and laser therapy with antioxidant medication. Several clinical indices were utilized for parodontal tissue assessment (PMA, SBI, AP), resistance of gingival capillary bed, osteal resorption. The lipid peroxide oxidation was determined by MDA, Fe2+ MDA  and phospholipase A2.   Additional implementation of laser and metabolic therapies sufficiently increases efficacy of conventional therapy and improves secondary prevention of chronic parodontitis. A marked decrease in structural-functional deviations and apparent recovery of microcirculatory vascular bed of parodontal tissue has been achieved. .
