Thirty patients with lepromatous leprosy of long duration were examined for gingival and periodontal changes. All patients presented with chronic gingivitis and periodontitis of an unspecific type. Etiologic factors affecting the development of gingival and periodontal changes in this disease are: lack of oral hygiene with severe plaque and calculus formation due to the inability of the patients to perform oral hygiene, mouth breathing, specific granulomatous infiltrations, and a possible specific drug action. Specific changes in form of 'facies leprosa' are not pathognomonic of lepromatous leprosy but may be found in 20% of the cases among Thai and Chinese patients. Occurrence and pathogenesis of 'facies leprosa' is described.
对30例病程较长的瘤型麻风患者进行了牙龈和牙周变化检查。所有患者均表现为非特异性类型的慢性牙龈炎和牙周炎。影响该疾病牙龈和牙周变化发展的病因包括：由于患者无法进行口腔卫生护理导致口腔卫生不良，形成严重的菌斑和牙石；口呼吸；特异性肉芽肿浸润；以及可能的特定药物作用。“麻风面容”形式的特异性变化并非瘤型麻风所特有，但在泰国和中国患者中，20%的病例可能会出现。本文描述了“麻风面容”的发生情况和发病机制。
