Study phase:

New Treatment Measure Clinical Study

研究设计:

非随机对照试验 

Study design:

Non randomized control 

研究目的:

对于不可复性牙髓炎早期患者,采用减压膜减压+牙髓再生治疗,促进牙髓的修复再生,保留活髓,从而研究减压再生治疗方案对治疗不可复性牙髓炎的预后疗效。  

Objectives of Study:

For patients with early irreversible pulpitis, a treatment combining decompression membrane and pulp regeneration is adopted to promote repair and regeneration of the pulp and to preserve the vital pulp. This study aims to investigate the therapeutic efficacy of the decompression and regeneration treatment for irreversible pulpitis.

纳入标准:

Inclusion criteria

排除标准:

1. 患牙出现“热痛冷缓解”、甚至冷刺激无反应(即化脓及坏死牙髓)。 2. 患牙有越过边缘嵴的隐裂纹等需要冠修复的情况。 3. 患者有中至重度牙周炎、或患牙有牙周牙髓联合病变。 4. 患牙有根尖周病变或牙根的内外吸收。 5. 去净腐质后显微镜下观察牙髓出现明显的液化坏死,牙髓创面出血难以控制。 6. 患者无法按时复诊。

Exclusion criteria:

1. The affected tooth exhibits symptoms such as "heat pain relieved by cold" or even no response to cold stimulation (indicating abscessed and necrotic dental pulp). 2. In cases where the affected tooth has cracks that extend beyond the marginal ridge or other conditions requiring crown restoration. 3. The patient has moderate to severe periodontitis, or the affected tooth has combined periodontal and pulpal pathology. 4. The tooth has periapical lesions or internal or external root resorption. 5. The pulp is obviously liquefied and necrotic under the microscope after removing the decay, and the bleeding from the pulp wound is difficult to control. 6. The patient is unable to return to the clinic on time.
