研究目的: |
评估浓缩生长因子(CGF)在牙根外吸收患牙中促进牙根修复性再生的有效性与安全性,并探讨其对邻牙预后的影响,从而为牙根外吸收患牙的长期保存提供客观依据 |
||||||||||||||||||||||
|
Objectives of Study: |
To evaluate the efficacy and safety of concentrated growth factor (CGF) in promoting reparative regeneration of root structure in teeth affected by external root resorption, and to investigate its impact on the prognosis of adjacent teeth, thereby providing objective evidence for the long-term preservation of teeth with external root resorption. |

纳入标准: |
1.年龄18-45岁,性别不限; 2.有阻生牙拔除适应证; 3.CBCT显示邻牙牙根远中面或根尖存在局限性外吸收区域,且与阻生牙的牙冠密切接触; 注:所有病例由两名具有影像阅片经验的口腔医生独立判断为“阻生牙致邻牙外吸收”,如意见不一致,则由第三名高级别医师裁定; 4.排除其他明确诱因(如正畸、外伤、肿瘤或囊肿等); 5.外吸收患牙为已萌出恒牙,无牙髓牙周病变,牙髓电活力测试正常; 6.无拔牙禁忌证者; 7.患者自愿签署知情同意书,同意参与试验并依从方案。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Male or female participants aged 18 to 45 years. 2. Patients who meet the indications for extraction of an impacted tooth. 3. Cone-beam computed tomography (CBCT) demonstrates a localized area of external root resorption on the distal surface or apex of the adjacent tooth root, closely contacting the crown of the impacted tooth. Assessment method: All cases are independently evaluated by two experienced oral radiologists. In case of disagreement, the diagnosis will be determined by a third senior radiologist. 4. Patients with no other identifiable causes of external root resorption, such as orthodontic treatment, trauma, tumor, or cyst. 5. The tooth affected by external root resorption is a fully erupted permanent tooth, with no pulp or periodontal pathology, and demonstrates normal pulp vitality on electric pulp testing. 6. No contraindications to tooth extraction. 7. The participant has voluntarily signed the informed consent form and agrees to participate in the study and comply with the study protocol. |
||||||||||||||||||||||
|
排除标准: |
1.合并严重全身性疾病,不能耐受口腔手术; 2.妊娠或近期有妊娠计划者; 3.外吸收患牙存在明显牙体牙周病变; 4.放射性或药物性颌骨骨髓炎患者; 5.既往或当前使用影响骨/牙周愈合的药物(如长期糖皮质激素、抗骨吸收药等); 6.精神病患者或认知障碍患者; 7.正在接受正畸治疗者; 8.1个月内参加过其他临床试验者; 9.研究者判断不适合入组的其他情况。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Presence of severe systemic disease rendering the patient unable to tolerate oral surgery. 2. Pregnant or planning to become pregnant in the near future. 3. The tooth affected by external root resorption shows obvious coronal or periodontal pathology. 4. Diagnosis of radiation-induced or medication-related osteomyelitis of the jaw. 5. Current or prior use of medications known to affect bone or periodontal healing (e.g., long-term corticosteroids or antiresorptive agents). 6. Patients with psychiatric disorders or cognitive impairment that may affect compliance. 7. Patients currently undergoing orthodontic treatment. 8. Participation in another clinical trial within the past one month. 9. Any other condition deemed unsuitable for inclusion by the investigator. |

随机方法(请说明由何人用什么方法产生随机序列): |
采用计算机生成的区组随机法,区组大小为4,分配比例为1:1。随机序列由独立统计人员生成,并由不参与临床操作的研究人员管理。本研究为涉及具体手术操作的临床研究,术者需根据分组实施不同的手术方式,研究过程中无法对术者及受试者实施盲法,因此不采用隐蔽分组。为降低偏倚风险,结局指标由未参与手术的独立评估人员进行评价,并按照统一标准进行数据收集与分析。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The study adopts a computer-generated block randomization method with a block size of 4 and a 1:1 allocation ratio. The randomization sequence is generated by an independent statistician and managed by study personnel who are not involved in clinical procedures. This is a surgical study; surgeons must be aware of group allocation during the procedure, thus blinding of surgeons and participants is not feasible. Randomization sequence will be generated by an independent statistician (block size = 4). Allocation concealment will be ensured by sealed, opaque, sequentially numbered envelopes (SNOSE) / or a central randomization system. Outcome assessors and imaging evaluators, who are not involved in surgery, will remain blinded to group assignments. |

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
At present, this study has no plan to share individual participant data. The primary reasons include the need to protect participant privacy, limitations of the current ethical approval scope, and data security management requirements. If conditions become appropriate in subsequent phases of the study, the feasibility of data sharing will be evaluated in accordance with ethical and legal regulations. |
