Outline of Final Research Achievements

Nine patients treated for weight loss and took periodontal examinations were not affected with severe periodontitis. Two patients of them were affected with gingivitis. Serum IgG antibodies of Porphyromonas gingivalis (Pg) correlated with BOP number.
Average serum IgG antibodies of Pg of thirty-two patients treated for weight loss two-SD higher than the health, it was not change after the treatment.
