Background: 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 a contributing factor in the development of periodontitis. They are most commonly found at the buccal surfaces of mandibular molars. Methods: A 57-year-old female was referred to our clinic for treatment of chronic periodontitis. Clinical examination revealed moderate attachment loss that was localized to the palatal side of the maxillary secondary molars. The rest of the dentition was less affected, with a diagnosis of generalized slight chronic periodontitis. 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. Results: Due to the fact that surgical intervention exposed the CEPs, they were not removed. After the active therapy, which resulted in inflammation resolution and maintainable probing depth, the patient was placed on a three-month recall for periodontal maintenance. Conclusions: This case report presents CEPs in an unusual location in the palatal roots of maxillary secondary molars. CEPs confirm their role 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,可受牙齿相关局部因素的影响而改变。颈缘釉突(CEPs)是一种常见的牙齿异常,可成为牙周炎发展的一个促成因素。它们最常见于下颌磨牙的颊面。方法:一名57岁女性因慢性牙周炎被转诊至我们的诊所。临床检查发现中度附着丧失,局限于上颌第二磨牙的腭侧。其余牙列受影响较小,诊断为广泛性轻度慢性牙周炎。先进行了初始非手术牙周治疗,随后在上颌左右后部区域进行了根向复位瓣手术。手术时,在牙周组织受影响最严重的部位发现了CEPs。结果:由于手术干预暴露了CEPs,未将其去除。在积极治疗使炎症消退且探诊深度可维持后,患者被安排每三个月复诊进行牙周维护。结论:本病例报告展示了CEPs出现在上颌第二磨牙腭根的不寻常位置。CEPs证实了它们作为局部促成因素在局限性慢性牙周炎中的作用。
