慢性牙周炎是由口腔混合茵群引起的慢性感染性疾病,能够造成牙周支持组织破坏,最终导致牙齿缺失、影响咀嚼功能。多种复杂因素能够影响牙周疾病的发生、发展和预后,其中全身因素在影响疾病发展变化和指导临床治疗工作中具有重要作用。本文将对慢性牙周炎全身相关危险因素进行简要阐述。

种植修复目前已经成为牙列缺损后常见的修复方法,发生于颌骨的囊肿通常会导致大量骨质破坏,尤其是上颌前牙区为囊肿多发部位,临床中摘除囊肿并拔除患牙后通常会造成大面积骨缺损,最终使种植修复面临很大困难。目前,多种骨增量手术可有效解决这一问题。自体骨是移植材料的金标准,但术后自体骨不可预知的吸收常影响临床效果。本文就1例上颌前牙囊肿摘除术后的病例,取下颌骨外斜线自体骨块Onlay植骨联合

牙根内吸收是指根管内发生的进行性病理性吸收,无明显的临床症状,多在X线检查时偶然发现．一般表现为膨出于根管的圆形或卵圆形透射影．有时是根管影像的整体性增宽,严重的牙根内吸收可导致牙齿丧失。

88例甲状舌管囊肿临床病理分析

目的回顾性研究88例甲状舌管囊肿，总结其临床病理特点。方法光镜下观察术后标本的病理切片，并复查其临床资料。结果10岁以下的儿童为6250％，11～20岁的青少年为15.90％；囊肿分布舌骨厂为54.54％，舌骨上为26.14％舌肌水平19.33％；囊肿衬里上皮的形态依次为假复层纤毛柱状上皮（30.67％），扁平上皮（29.55％）皮复层鳞状上皮（14.77％）。结论甲状舌管囊肿为好发于青少年的发育性囊肿，其衬里上皮多样，治疗小彻底易复发。     

Radiofrequency coblation assisted transoral excision of lingual thyroglossal duct cyst

Radiofrequency coblation (RFC) is a relatively new device that has been used in several transoral procedures. Currently, clinical data on its use for excising lingual thyroglossal duct cyst (LTGDC) are lacking. Herein, we conducted this retrospective case series to explore the feasibility and efficacy of RFC-assisted transoral surgery (RFC-TOS) in excising LTGDC. A total of 12 LTGDC patients between 2013 and 2020 were retrospectively studied. The cysts of these patients were all fully removed along the boundary to the depth of the hyoid using RFC wands. All surgeries were completed within 30 minutes. Only one patient had an intraoperative blood loss of more than 10 ml. All patients started oral feeding on the day of operation. The mean postoperative hospital stay was only 3.3 days (range 1-8 days). No surgical-related short-term and long-term complications were observed. One patient was lost to follow up, and no recurrences occurred during a mean follow-up period of 52.7 months among the other 11 patients. Therefore, we believe that RFC is a reliable tool in transoral operation for treating LTGDC. LTGDC patients who underwent RFC-TOS showed quick recovery, low risks of complications, and excellent clinical and functional outcomes.

60例甲状舌管囊肿临床分析

目的探讨甲状舌管囊肿临床流行病学特点以提高手术治疗效果。方法对60例甲状舌管囊肿的临床表现、病理特点和治疗效果进行回顾性分析。结果甲状舌管囊肿以儿童好发,女性多于男性,舌骨及舌骨以下水平多见;多数甲状舌管囊肿位于颈正中线附近,极少数表现为颌下囊肿;囊肿以单个为主,少数表现为多个囊肿;多数病例术后可探查到管状物或条索状物。甲状舌管囊肿病理组织学表现呈多样性特征,治疗不当易复发。结论甲状舌管囊肿的临床表现及病理特点均表现为多样性特征,手术不当易复发。

A primordial cyst without keratinization in the maxillary molar region: a case report

In this article we report a case of a 54-year-old man with a primordial cyst in the left maxillary molar region. We performed conventional radiographs and computed tomography (CT) without contrast enhancement, but it was difficult to determine whether the lesion was a tumor or a cyst. CT images with contrast medium showed a cyst, not a tumor. Histopathologically, the cyst wall was composed of fibrous connective tissue lined by nonkeratinized squamous epithelium. Based on its clinical, radiological, and histopathological findings, this lesion was diagnosed as a primordial cyst. This case indicated that enhanced CT imaging is useful for differentiating between cysts and benign tumors and that there are no specific differences in the radiological appearance between primordial cysts and odontogenic keratocysts

Radiographic analysis of a calcifying odontogenic cyst

The Radiographic appearance of 33 cases of calcifying odontogenic cyst (COC) from 1971 to 1998 were analyzed. COC has a variety of radiographic appearances. According to the WHO classification¹⁾, such cysts can be divided into five subtypes in order to be considered as central COC and one peripheral type. The subtypes are as follows: I: Unilocular, II: COC associated with odontoma, III: alveolar bone type, IV: compound type, V: recurrences that have become malignant. Ghost cells are an important feature in the diagnosis of COC. However, ghost cells may occur in other tumors as well. Differentiation of the types of COC according to radiographic appearance will aid the clinical diagnosis and treatment of odontogenic cysts.     

Traumatic bone cyst: case report

Abstract The traumatic bone cyst is a lesion whose aetiology and pathogenesis have not been conclusively established. There are several theories and names for this lesion and various forms of management have been reported in the literature. This report outlines the clinical and radiographic findings associated with a case of a traumatic bone cyst. Laboratory investigations were also carried out and their findings are reported. This case was treated jointly by the endodontic and oral surgery departments of an institution and demonstrates the need for close follow-up from both departments. In particular, the endodontic aspects of monitoring the pulp status of teeth in the region of such a bone lesion are emphasised.
