光动力学照射小鼠牙周组织的病理变化
Pathological changes of mouse periodontal tissues following photodynamic therapy
摘要
Abstract
BACKGROUND:Photodynamic therapy (PDT) may have bad effects on oral cavity tissue, so the biological safety evaluation is necessary before Toluidine blue O (TBO)-mediated PDT of dentine caries in clinic.OBJECTIVE:To observe the effects of photosensitization of the TBO-mediated PDT to periodontal tissues in mice.METHODS:Fifty-four mice were randomly divided into nine groups, and were respectively treated with 0 mg/L, 50 mg/L, 100 mg/L TBO with 0, 15, 25min LED illumination. Periodontal tissue slices were taken to observation after treatment of 72 hours.RESULTS AND CONCLUSION:There were no abnormal changes like necrosis, ulcer or hyperplasia happens in the mice gingival,alveolar bone or teeth after light treatment. This indicated that TBO-mediated PDT was safe to the prevention of dental caries,without damaging effect to periodontal tissues adjacent to the teeth.关键词
