Abstract

|
Necrotizing periodontal disease caused by plaque bacteria is showed clinical findings including pseudo-membrane, interproximal necrosis of the affected area, pain on palpation and gingiva bleeding. Microbiological examination is showed that patients have fusospirochetal bacteria. Two patients who were provisionally diagnosed as necrotizing periodontal disease received nonsurgical periodontal treatments in conjunction with dressing using 3% hydrogen peroxide and local antibiotic delivery. Before and 3 - 5 days after initial treatment, the levels of periodontal bacteria in gingival crevicular fluid obtained using quantitative PCR were compared. After treatment, patients recovered normal gingiva. The number of periodontal diseases related bacterial species decreased from seven or eight to one. As a result, periodontium of patients with necrotizing periodontal disease was recovered to normal periodontium by nonsurgical periodontal treatments.
