本文对口腔组织的放射效应及处理进行了研究。口腔组织的放射效应口腔粘膜:放疗早期(2—3周)粘膜出现红斑,最后发展为广泛的溃疡、脱屑。有时可导致相当严重的放射性粘膜炎。通常可在放疗后2—3周内痊癒。在此期间,由于淋巴回流障碍,偶尔并发水肿。自色念珠菌感染是放疗期间常见的并发症。放疗后,粘膜上皮变薄、萎缩、其下方的结缔组织发生纤维化和无血管化,从而,给义齿修复带来困难。味蕾:经1000rad照射则出现味蕾变性
In this paper, the radiation effects and treatment of oral tissues were studied. Radiation effects in oral tissues Oral mucosa: erythema in the mucosa early in the radiotherapy (2-3 weeks), eventually developing extensive ulceration and scaling. Sometimes it can cause quite serious radiation mucositis. It can usually be cured within 2-3 weeks after radiotherapy. During this period, due to lymphatic drainage disorders, occasionally complicated by edema. Candida albicans infection is a common complication during radiotherapy. After radiotherapy, mucosal epithelium thinning, atrophy, the connective tissue below it fibrosis and avascular, thus, to the denture repair difficulties. Taste buds: 1000rad exposure occurs when the taste buds degeneration
