慢性剥脱性龈炎的临床特点是游离龈和附着龈充血、剥脱。1932年Prioz将严重龈上皮剥脱的病例首次命名为“慢性弥散性剥脱性龈炎”。病损中,牙龈受累的程度和范围不同:有时充血仅伴有较轻的剥脱,一些病例,上皮能从无溃烂的区域轻易剥下;另些病例,则显示出结缔组织面的广泛暴露区。病人可能无症状或有烧灼感,或有剧烈疼痛。本病女性比男性多,青春期任何年龄皆可发病,而以30岁以后较多。本病的缓解和加重时期不定,牙龈损害可能在几月后愈合,病情也可持续数年。本病病因尚难确定,早期的研究者认为是单一的病因。以后考虑到的病因学因素包括雌激素缺乏、甲状腺机能减退和营养缺乏等,但Glickman等曾考虑本病主要是一种 The clinical features of chronic exfoliative gingivitis are gingival hyperemia and exfoliation. In 1932, Prioz named the first case of severe gingival exfoliation as “chronic disseminated exfoliative gingivitis.” In lesions, the extent and extent of gingival involvement vary: sometimes there is only mild exfoliation of the hyperemia, and in some cases, the epithelium can be easily peeled off from the non-ulcerated area; in other cases, the area of ​​extensive connective tissue exposure . The patient may be asymptomatic or have a burning sensation, or have severe pain. The disease more women than men, adolescence can be any age, but more after 30 years of age. The disease eases and exacerbates the period of uncertainty gum damage may be healing in a few months, the condition may also continue for several years. The etiology of the disease is still difficult to determine, early researchers believe that the single cause. Etiological factors to be considered later include estrogen deficiency, hypothyroidism and nutritional deficiencies, but Glickman et al. Have considered the disease is mainly a
