Abstract

Cervical enamel projections (CEPs) represent a unique developmental and anatomical anomaly wherein the enamel structure extends apically beyond the cemento-enamel junction of the tooth. In this scoping review, the existing literature on CEPs was evaluated to delineate their characteristics, prevalence, predilection for specific teeth and surfaces, clinical significance, and management approaches. Searches were conducted on MEDLINE (PubMed), Cochrane Library, and Embase databases using the keywords “enamel projection(s)” or “ectopic enamel.” In total, 24 studies meeting inclusion criteria were included in the review. The prevalence of CEPs varied widely (8.3%–85.1%), predominantly manifesting as grade I or grade III. Mandibular first and second molars exhibited a higher incidence of CEPs, with a notable predilection for buccal surfaces. The consensus in most studies was that CEPs are associated with localized periodontal diseases. Recommendations inclined toward the removal of ectopic enamel during periodontal surgery to enhance periodontal attachment formation. However, decision-making should involve careful consideration of the benefits and drawbacks based on individual circumstances.

从牙周角度看牙颈部釉质突起:范围综述。
牙颈部釉质突起(CEPs)是一种独特的发育和解剖异常,其釉质结构向顶部延伸,超出了牙齿的牙本质-釉质交界处。在此次范围审查中,我们评估了有关 CEPs 的现有文献,以确定其特征、发病率、对特定牙齿和表面的偏好、临床意义和管理方法。使用关键词 "釉质突起 "或 "异位釉质 "在 MEDLINE (PubMed)、Cochrane Library 和 Embase 数据库中进行了检索。符合纳入标准的研究共有 24 项。CEPs的发病率差异很大(8.3%-85.1%),主要表现为I级或III级。下颌第一和第二磨牙的 CEP 发生率较高,且明显偏向于颊面。大多数研究一致认为,CEPs 与局部牙周疾病有关。建议倾向于在牙周手术中去除异位釉质,以促进牙周附着的形成。不过,在做决定时应根据个人情况仔细考虑利弊。

期刊介绍: Clinical Anatomy is the Official Journal of the American Association of Clinical Anatomists and the British Association of Clinical Anatomists. The goal of Clinical Anatomy is to provide a medium for the exchange of current information between anatomists and clinicians. This journal embraces anatomy in all its aspects as applied to medical practice. Furthermore, the journal assists physicians and other health care providers in keeping abreast of new methodologies for patient management and informs educators of new developments in clinical anatomy and teaching techniques. Clinical Anatomy publishes original and review articles of scientific, clinical, and educational interest. Papers covering the application of anatomic principles to the solution of clinical problems and/or the application of clinical observations to expand anatomic knowledge are welcomed.
