研究目的:

非龋性颈部缺损(NCCLs)是指在某些因素长期作用下,发生在牙釉质和牙骨质交界处非龋损导致的牙体硬组织丧失,是一类在牙体牙髓科常见的非龋性疾病。NCCLs在人群中患病率很高,且往往累及多颗患牙;可引起牙本质敏感、牙髓炎、根尖周炎等症状。门诊病人中,龈方边缘位于牙龈以下的龈下NCCLs十分常见,但目前导致其发生的危险因素尚不明确。在治疗龈下NCCLs时,有诸多难点,常会导致充填修复的失败。本课题收集临床患者,通过临床检查将患者分为无NCCLs的对照组和有NCCLs的龈上NCCLs和龈下NCCLs组,填写调查问卷并检查患牙的牙体情况和牙周情况等,以评估NCCLs的临床特征及其相关风险因素,为精准化预防龈下NCCLs提供依据;对于有龈下NCCLs的患者,根据患者的临床情况选择合适的治疗方案,并记录治疗后的修复体状况和牙周情况,评估不同的修复方式的远期效果,为临床上选择合适的龈下NCCLs修复方案提供指导;对需要牙体联合牙周手术治疗龈下NCCLs的患者,进行远期效果随访和评估,为建立功能和美观兼顾的修复方案提供依据。  

Objectives of Study:

Non?carious cervical lesions (NCCLs) refer to the loss of hard tissue at the cemento-enamel junction (CEJ) in the absence of caries under the long-term action of certain factors. It is a common type of non-caries disease in endodontics department. NCCLs have a high prevalence in the population, and often involve multiple teeth and can cause dentine sensitivity, pulpitis, and periapical periodontitis. In outpatients, subgingival NCCLs are very common, but the related risk factors for their occurrence are still unclear. There are many difficulties in the treatment of subgingival NCCLs, which often lead to the failure of repair. In this study, clinical patients will be collected and divided into a control group without NCCLs and a supragingival NCCLs and subgingival NCCLs groups with NCCLs through clinical examination. The patients will be instructed to fill the questionnaire and examined to gather the dental and periodontal conditions of the affected tooth. The clinical characteristics of NCCLs and related risk factors was evaluated to provide the basis for precise prevention of subgingival NCCLs.For patients with subgingival NCCLs, appropriate treatment plan was selected and performed, then the status of the restoration and periodontal conditions after treatment will be recorded to evaluate the long-term effects of different repair methods, to provide guidance for appropriate clinical treatment selection of subgingival NCCLs. For patients with subgingival NCCLs who need multidisciplinary treatmenttreat, the long-term effect will be evaluated to provide a basis for establishing a functional and aesthetic restoration program.

药物成份或治疗方案详述:

1.研究与龈下NCCLs发生相关的风险因素 指导所有纳入患者填写调查问卷,了解患者的口腔卫生习惯及饮食习惯等。对NCCLs组患者进行口腔检查,包括NCCLs缺损形态(宽度和深度)、缺损与釉牙骨质界的关系、咬合面磨损情况等牙体组织和牙龈生物型、牙龈退缩、附着丧失、附着龈宽度等牙周组织的检查,并记录缺损与牙龈的位置关系,以评估NCCLs的基本发病情况及导致龈下NCCLs发生的相关风险因素,包括患者口腔习惯及牙体牙周组织结构。周情况选择合适的牙周手术方案,如切龈术、冠延长术和膜龈手术,暴露龈侧边缘或增加附着龈宽度,改善美观问题。手术前或手术后进行纳米树脂充填修复。 2.评估各种龈下NCCLs充填修复方式的远期效果 2.1 根据患者的临床情况选择合适的龈下NCCLs治疗方式,包括直接树脂充填修复和间接树脂嵌体修复。 2.2修复1周后复查,记录治疗后的修复体状况和牙周情况。检查并记录以下内容作为基线:修复体情况包括原充填物(复合树脂/树脂嵌体)表面情况(光滑/粗糙)、有无脱落、有无暴露牙本质或基底、边缘是否密合、边缘有无着色、有无继发龋;牙周情况包括探诊深度、探诊出血、菌斑指数、有无新的牙龈退缩和附着丧失;并记录牙本质敏感程度。 2.3患者6个月、1年、2年、3年、5年复查并记录2.2中的各参数,并与基线数据进行对比;取患牙及无修复体的对照牙的龈沟液,检测其中炎性因子的表达量进行对比;收集患牙及无修复体的对照牙的龈下菌斑,检测其中某种牙周致病菌的含量并进行对比。通过分析以上数据,评估不同充填修复方式的远期效果。 3.评估联合牙周手术治疗龈下NCCLs的修复方式的远期效果 3.1收集无法通过排龈等方式完全暴露龈下NCCLs的龈侧边缘的病例;龈下NCCLs伴明显的牙龈退缩和牙根暴露,导致附着龈过窄或丧失,或涉及美观问题的病例。 3.2根据患牙的缺损和牙周情况选择合适的牙周手术方案,如切龈术、冠延长术和膜龈手术,暴露龈侧边缘或增加附着龈宽度,改善美观问题。手术前或手术后进行纳米树脂充填修复。 3.3治疗结束后记录修复体状况和牙周情况,检查并记录2.2中描述的项目。患者6个月、1年、2年、3年、5年复查并记录以上参数,并与基线数据进行对比;取患牙及无修复体的对照牙的龈沟液,检测其中炎性因子的表达量进行对比;收集患牙及无修复体的对照牙的龈下菌斑,检测其中某种牙周致病菌的含量并进行对比。通过分析以上数据,评估不同修复方式的远期效果。 

Description for medicine or protocol of treatment in detail:

1. Study on the related risk factors of the occurrence of subgingival NCCLs All included patients will be instructed to fill in the questionnaire to know the oral hygiene habits and eating habits of patients. Oral examination will be performed on patients with NCCLs, including dental structure, such as lesions morphology (width and depth), the relationship between lesions and enamel-cementum junction, occlusal surface wear, and periodontal structure, such as gingival biotypes, gingival recession, loss of attachment, and width of attached gingiva. The positional relationships between the lesions and the gingiva will be recorded. All information will be gathered to evaluate the clinical characteristics of NCCLs and the related risk factors that lead to the occurrence of subgingival NCCLs. 2. Assess the long-term effects of various filling and repair treatment of subgingival NCCLs 2.1 According to the patients clinical condition, the appropriate treatment, including direct resin filling and indirect resin inlay repair. 2.2 The condition of the restorations and periodontal conditions after treatment will be recorded after 1 week. Check and record the followings as the baseline: condition of the restorations, including the surface of the original fillings (smooth/rough), falling off of fillings, dentin or base exposition, Edge tightness of fillings, edge staining and secondary caries, and periodontal conditions, including probing depth, probing bleeding, plaque index, and whether there is new gingival recession and loss of attachment, and the degree of dentin sensitivity. 2.3 Patients will review after 6 months, 1 year, 2 years, 3 years, and 5 years, and the parameters in 2.2 will be recorded and compared with the baseline data. Gingival crevicular fluid of the repaired teeth and control normal teeth were collected and tested to compare the expression of inflammatory factors. The subgingival plaques of the repaired teeth and control normal teeth were collected, and the content of periodontal pathogens was detected. the long-term effects of different treatment will be evaluated through the comparison and analysis of the above data. 3. Evaluation of the long-term effect of treatment combined periodontal surgery for subgingival NCCLs 3.1 Cases where the gingival edge of subgingival NCCLs cannot be fully exposed by gingival retraction; cases where subgingival NCCLs are accompanied with obvious gingival recession and root exposure, resulting in narrow attached gingiva or loss of attached gingiva; cases involving aesthetic problems will be collected. 3.2 The appropriate periodontal surgery plan was selected, such as gingival incision, crown lengthening and membranous gingival surgery, to expose the gingival edge or increase the width of the attached gingiva. Resin filling will be performed before or after surgery. 3.3 After the treatment, the restoration and periodontal condition will be checked and recorded as described in 2.2. Patients should review after 6 months, 1 year, 2 years, 3 years, and 5 years and the above parameters will be recorded and compared with baseline data. Gingival crevicular fluid of the repaired teeth and control normal teeth were collected and tested to compare the expression of inflammatory factors. The subgingival plaques of the repaired teeth and control normal teeth were collected, and the content of periodontal pathogens was detected. the long-term effects of different treatment will be evaluated through the comparison and analysis of the above data.
