研究目的: |
本研究通过两部分前瞻性随机对照试验,评估国产新型含锶生物陶瓷材料C-Root BP用于根尖手术倒充填治疗慢性根尖周炎和活髓切断术治疗年轻恒牙龋源性慢性牙髓炎的临床疗效(与iRoot BP Plus、MTA对比),旨在为其在根尖外科及活髓保存治疗中的临床应用提供高级别临床循证医学证据。研究成果有望推动高性能国产生物材料的临床转化,为临床医生提供新的、有效的治疗选择,最终提升牙体保存治疗的成功率与远期预后。 |

Objectives of Study: |
This study evaluates the clinical efficacy of the novel domestic strontium-containing bioceramic material C-Root BP in apical retrofilling for chronic apical periodontitis and in pulpotomy for carious chronic pulpitis in young permanent teeth (compared with iRoot BP Plus and MTA) through two prospective randomized controlled trials, aiming to provide high-level clinical evidence-based medical evidence for its application in apical surgery and vital pulp therapy. The research outcomes are expected to promote the clinical translation of high-performance domestic biomaterials, offer new and effective treatment options for clinicians, and ultimately improve the success rate and long-term prognosis of tooth preservation treatment. |

Inclusion criteria |
Study 1 (Apical Surgery RCT): (1) Patients aged 18 to 60 years without major systemic diseases who can cooperate with surgical treatment and postoperative long-term follow-up; preoperative X-ray and CBCT examinations are performed. (2) Periapical cyst (single-root periapical cyst size <=8 mm in diameter). (3) Iatrogenic periapical lesions (e.g., overfilling of root canal, separated instrument, root canal deviation, lateral perforation, etc.). (4) Inability to complete root canal treatment/retreatment (e.g., calcified blockage in the apical region, post-and-core crown restoration, etc.). (5) Localized horizontal root fracture or cemental tear (periapical radiolucency area <=8 mm in diameter). (6) Chronic apical periodontitis deemed as treatment failure after non-surgical retreatment with follow-up exceeding 6 months, based on clinical examination and imaging findings (including recurrent swelling and pain, persistent sinus tract, no significant reduction in periapical radiolucency, etc.). Study 2 (Pulpotomy RCT): (1) Patients aged 6 to 14 years without systemic diseases who can cooperate with treatment; preoperative periapical radiographs or panoramic radiographs are taken to record root development status. (2) Preoperative clinical diagnosis of carious chronic pulpitis in immature permanent teeth: The affected tooth may present with food impaction pain and occlusal discomfort, spontaneous pain, but no radiating pain or history of gum swelling and pain; deep carious cavity, obvious probing pain or exposure of the pulp chamber and pulp can be detected, without root fracture or displacement, no percussion pain or percussion pain (+/-), no mobility, and pulp temperature testing shows delayed pain lasting several seconds to minutes. Preoperative imaging confirms immature permanent teeth with open apices, showing caries approaching or involving the pulp, intact and continuous periodontal ligament space (with possible widening), no periapical radiolucency, no internal or external root resorption, and no pulp chamber calcification. (3) During the procedure, after complete caries removal, pulp exposure occurs, and formed pulp tissue is visible. Hemostasis can be achieved within 10 minutes after pulpotomy. In deep carious teeth without typical clinical manifestations of pulpitis, when pulp exposure occurs after complete caries removal or even before complete caries removal, it should be diagnosed as "chronic pulpitis". In this study, all postoperative diagnoses are "chronic pulpitis". |

随机方法(请说明由何人用什么方法产生随机序列): |
两项临床研究均采用分层区组随机化。根据核心影响因素分层(研究一按牙位分层;研究二按患者年龄和露髓孔大小分层),每层内使用计算机生成随机序列,按1:1比例分配至试验组(C-Root BP)或对照组(iRoot BP Plus或MTA)。随机序列由独立统计人员保存于密封不透光信封中。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Both clinical studies adopted stratified block randomization. Stratification was based on key influencing factors (Study 1: tooth type; Study 2: patient age and size of the pulp exposure site). Within each stratum, a computer?generated random sequence was used to allocate participants in a 1:1 ratio to either the experimental group (C?Root BP) or the control group (iRoot BP Plus or MTA). The random allocation sequences were kept by an independent statistician in sealed, opaque envelopes. |

|
盲法: |
实施“评估者盲法”。负责术后随访、数据收集(尤其是影像学评估)的研究人员对患者分组信息保持盲态。由于材料外观和调拌方式不同,对术者设盲不现实,但要求术者不向患者和评估者透露所用材料。 |
|
Blinding: |
Implementation of assessor blinding. Researchers responsible for postoperative follow-up and data collection (especially radiographic assessment) remained blinded to patient group allocation. Blinding of the operators was not feasible due to differences in the appearance and handling/mixing procedures of the materials; however, operators were instructed not to disclose the material used to either the patients or the assessors. |
