牙颈部釉突(CEPs)是磨牙釉质从釉牙骨质界向根分叉的突起。以往学者们对磨牙CEPs和牙周根分叉感染的关系有不同看法。本研究的目的是评价磨牙根分叉受累者的:(1)CEPs的发生、分布和程度;(2)根分叉感染程度与CEPs的关系;(3)无论有、无CEPs磨牙颊侧相邻牙周组织的健康状况;(4)CEPs的双侧对称性。作者用探诊、牙周X片、翻瓣术和望诊检查了78名21到61岁的根分叉受累患者。按Masters和Hoskins体系及Glickman的分度标准记录患者年龄(分四组:21～30;31～40;41～50;≥51岁)、性别、磨牙颊和
Cervical glaucoma (CEPs) is the protrusion of the molars enamel from the enamel to the root of the enamel. In the past scholars have different views on the relationship between molar CEPs and periodontal root bifida infection. The purpose of this study was to evaluate the effects of CEPs on the involvement of (1) the occurrence, distribution and extent of CEPs; (2) the relationship between root bifurcation and CEPs; (3) Adjacent periodontal tissue health status; (4) Bilateral symmetry of CEPs. The authors examined 78 patients with root bifurcation between the ages of 21 and 61 years with probing, periodontal X, flap surgery and look-up. According to Masters and Hoskins system and Glickman's indexing criteria, the patient's age (four groups: 21-30; 31-40; 41-50;
