研究目的:

1.评估自体静脉血血运重建术在年轻恒牙治疗中的临床疗效,包括临床症状的改善与消除、牙根和牙髓组织的再生情况以及牙齿整体健康和功能的提升程度。 2.对比自体静脉血支架与传统支架在促进根尖孔闭合、牙根发育等方面的疗效差异,为牙髓血运重建术的支架选择提供科学依据。  

Objectives of Study:

1. Evaluate the clinical efficacy of autologous venous revascularization in the treatment of young permanent teeth, including improvement and elimination of clinical symptoms, regeneration of root and pulp tissues, and overall improvement of tooth health and function. 2. Compare the therapeutic differences between autologous venous blood stents and traditional stents in promoting apical foramen closure and root development, and provide scientific basis for the selection of stents for pulp revascularization surgery.

Outcomes:

指标中文名:

根长

指标类型:

主要指标

Outcome:

Root length

Type:

Primary indicator

测量时间点:

1年,2年,3年

测量方法:

1. 影像学检查:使用X线片(根尖片)来获取牙齿的影像。 2. 图像校正:使用ImageJ软件(Version 1.4)及TurboReg插件对术前和术后的根尖片进行统一校正,以消除投照角度差异对测量结果的影响。 3. 测量指标: a) 根长(Root Length, RL):从牙冠到根尖的长度。 b) 根尖孔直径(Apical Foramen Diameter, AFW):根尖孔的直径。 c)

Measure time point of outcome:

1 year, 2 years, 3 years

Measure method:

1. Imaging examination: Use X-rays (periapical films) to obtain images of teeth. 2. Image correction: Use ImageJ software (Version 1.4) and TurboReg plugin to perform unified correction on preoperative and postoperative periapical radiographs to eliminate the influence of differences in projection angles on measurement results. 3. Measurement indicators: a) Root Length (RL): The length from the dental crown to the root tip. b) Apical Foramen Diameter (AFW): The diameter of the apical foramen. c)

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Sixty young permanent teeth with irreversible pulpitis and acute or chronic periapical periodontitis who visited the hospital due to dental caries, dental trauma and other causes were recruited. The cases were collected and entered into the electronic medical record system and the related clinical data collection system for standardized management, and regular follow-up was conducted.
