本文报导作者对早期牙釉质龋病变进行继续研究的结果。对25颗早期釉质龋和5颗人工龋的标本进行了观察,结果证明早期牙釉质龋的破坏先自牙面开始,以后沿牙釉柱方向穿过表层牙釉质往表层下进行,当病变达到生长线时,则沿生长线平面扩展。牙釉质的破坏开始表现为牙釉柱周围部分和柱心的溶解,以后整个牙釉柱被溶解。 This article reports the authors' continued study of early enamel carious lesions. 25 early enamel caries and 5 artificial caries specimens were observed, the results show that early damage to the enamel caries from the tooth surface, and then along the direction of the enamel through the surface enamel to the surface layer, when the lesions reached Grow line, then along the growth line plane expansion. Enamel destruction began to show the dissolution of the enamel around the part of the cylinder and the heart, after the entire enamel was dissolved.
