摘要:

釉珠是最常见的异位牙釉质,发生机制尚不明确。临床中釉珠主要通过影像学检查或引起相关临床症状时被发现。釉珠与牙周组织为半桥粒连接,这种连接减弱了牙周组织防御感染的能力。此外,釉珠的存在使菌斑免受唾液酶及口腔清洁措施的影响,利于菌斑滞留,易导致发生牙体牙髓和牙周疾病。釉珠的早期诊断、评估、处理具有重要的临床意义。本文通过回顾釉珠相关文献,对釉珠的命名、发生率、诊断及鉴别诊断、分类、形态特点、分布特点、理化性质、组织学特征、组织来源与发生机制、临床意义、处理策略等方面进行综述,为釉珠的临床诊治与进一步研究提供参考。

Abstract:

Enamel pearls (EPs) are the most common ectopic enamel. The etiology of EPs remains obscure. Clinically, EPs are mainly detected through radiographic examinations or when they elicit associated clinical symptoms. A hemidesmosomal junction exists between EP and periodontal tissue, which weakens the ability of periodontium to defend against infection. Furthermore, the presence of EPs facilitates plaque retention by shielding plaque from salivary enzymes and routine oral hygiene measures, which leads to endodontic and periodontal diseases. Therefore, early diagnosis, assessment, and management of EPs are of clinical importance. This article reviews the literature on EPs; it encompasses their nomenclature, prevalence, diagnosis and differential diagnosis, classification, morphological and distribution characteristics, physicochemical properties, histological features, histogenesis and pathogenesis, clinical implications, and management strategies, to provide a reference for their clinical diagnosis and management and further investigation.

Key words: enamel pearl, classification, prevalence, diagnosis, treatment
