Abstract

Objective

This report describes an unusual case of a lateral periodontal cyst (LPC) residing between the roots of a mandibular first and second molar.

Background

The LPC is a developmental odontogenic cyst, the majority situated along the lateral roots of the mandibular canines and premolars. The occurrence of an LPC solely confined to the molar region is extremely rare. Limited information regarding the LPC has appeared in the geriatric literature.

Patient Presentation

A unilocular cyst-like lesion was incidentally discovered on extraoral and intraoral radiographic examinations involving a 68-year-old patient. It was initially considered an infected odontogenic keratocyst or unicystic ameloblastoma.

Results

Histologic examination of the excised specimen revealed a thin cuboidal epithelial lining with focal nodular thickenings and underlying fibrovascular connective tissue wall. The lesion was diagnosed as an LPC. At a 6-month follow-up, the patient has remained asymptomatic and exhibited radiographic osseous regeneration.

Conclusions

The LPC should be added to the differential diagnosis of developmental odontogenic cysts found in the inter-molar region. A preoperative cone beam computed tomography scan may be helpful to optimise the surgical approach. Timely removal of any suspected cystic lesion, particularly in the context of infection in an older patient, may reduce postoperative sequelae and rule out malignancy.

牙间磨牙部位侧周囊肿:一位老年患者的新表现
目的本报告描述了一个不寻常的病例侧牙周囊肿(LPC)居住在下颌第一和第二磨牙的根之间。LPC是一种发育性牙源性囊肿,大多数位于下颌犬齿和前磨牙的侧根。LPC仅局限于磨牙区是极为罕见的。关于LPC的有限信息出现在老年文献中。一位68岁的患者在口外和口内x线检查中偶然发现单眼囊肿样病变。它最初被认为是感染的牙源性角化囊肿或单囊性成釉细胞瘤。结果病理检查显示薄的立方上皮衬里有局灶性结节增厚,下有纤维血管结缔组织壁。病变被诊断为LPC。在6个月的随访中,患者仍无症状,影像学显示骨再生。结论磨牙间区发育性牙源性囊肿的鉴别诊断应增加LPC检查。术前锥形束计算机断层扫描可能有助于优化手术入路。及时切除任何可疑的囊性病变,特别是在老年患者感染的情况下,可以减少术后后遗症并排除恶性肿瘤。

期刊介绍: The ultimate aim of Gerodontology is to improve the quality of life and oral health of older people. The boundaries of most conventional dental specialties must be repeatedly crossed to provide optimal dental care for older people. In addition, management of other health problems impacts on dental care and clinicians need knowledge in these numerous overlapping areas. Bringing together these diverse topics within one journal serves clinicians who are seeking to read and to publish papers across a broad spectrum of specialties. This journal provides the juxtaposition of papers from traditional specialties but which share this patient-centred interest, providing a synergy that serves progress in the subject of gerodontology.
