Periodontitis is primarily a bacteria-induced disease that can be modified by tooth-related local factors. Cervical enamel projections (CEPs) are a common tooth anomaly that can act as contributing factors in the development of periodontitis. They are most commonly found at the buccal surfaces of mandibular molars.
A 57-year-old female was referred to our clinic for treatment of chronic periodontitis. A clinical examination revealed moderate attachment loss that was localized to the palatal side of the maxillary second molars. The rest of the dentition was less affected, with a diagnosis of generalized slight chronic periodontitis. An initial non-surgical periodontal treatment was provided followed by apically positioned flap surgery in the maxillary right and left posterior areas. At the time of surgery, CEPs were found where the periodontium was most affected.
Because surgical intervention exposed the CEPs, they were not removed. After the active therapy, which resulted in inflammation resolution and maintainable probing depths, the patient was placed on a 3-month recall for periodontal maintenance.
CEPs were found in an unusual location on the palatal roots of maxillary second molars. The findings of this case report confirm the role of CEPs as a local contributing factor in localized chronic periodontitis.
牙周炎主要是一种由细菌引起的疾病,可以通过与牙齿相关的局部因素来改变。颈缘釉突(CEPs)是一种常见的牙齿异常,可能是牙周炎发展的促成因素。它们最常见于下颌磨牙的颊面。
一名 57 岁女性因慢性牙周炎到我院就诊。临床检查显示上颌第二磨牙腭侧有中度附着丧失。其余牙齿受影响较小,诊断为广泛轻度慢性牙周炎。首先提供了非手术牙周治疗,然后在右上和左上后牙区进行了牙向位瓣手术。手术时发现牙周组织受影响最严重的地方有颈缘釉突。
由于手术干预暴露了颈缘釉突,因此没有将其去除。积极治疗后炎症得到缓解且可维持的探诊深度,患者开始每 3 个月进行一次牙周维护的复诊。
在腭根上颌第二磨牙上发现了颈缘釉突位于不常见的位置。本病例报告的结果证实了颈缘釉突作为局部促成因素在局限性慢性牙周炎中的作用。
