摘要

这项研究的目的是了解牙根尖周炎年幼恒切牙的不成熟与成熟牙髓再生术的临床和影像学结果。 研究选取了 20 名 7 至 13 岁之间有外伤暴露的非活体年轻恒切牙。患者被分为两组:第一组--未成熟(包括牙齿数量=10),第二组--成熟(包括牙齿数量=10)。手术采用血块法作为支架。在牙本质-釉质交界处放置生物丁(约 2-3 毫米)作为覆盖材料。评估基于临床(疼痛、窦道、叩诊触痛、肿胀、活动度、修复体完好)和放射学(Nolla 分期、壁增厚、硬膜外连续性、髓室和髓道钙化、根尖周愈合、PAI 评分)参数。 经过 12 个月的随访,所有 19 颗牙齿均无临床症状。从影像学角度看,12 个月时牙根连续发育的百分比(未成熟组)为 100%(P = 0.000**)。12 个月后,X 光片显示未成熟组和成熟组的 PAI 分数均有所下降。在 12 个月的随访中,所有接受治疗的牙齿都没有对冷测试做出反应。成熟组中有一名患者没有接受干预。所有统计检验(卡方检验、曼-惠特尼U检验和费雪精确检验)均以5%的显著性水平进行。 未成熟组和成熟组的结果没有明显差异。

Comparative evaluation of the clinical and radiographic success of regenerative endodontic procedures in immature versus mature permanent incisors with apical periodontitis: A prospective observational study
The aim of the study was to know the clinical and radiographic outcomes of regenerative endodontic procedures of immature versus mature in young permanent incisors with apical periodontitis. Twenty non-vital, young permanent incisors with traumatic exposure between the age of 7 and 13 years were taken. Patients were divided into two groups: Group I – immature (number of teeth included = 10) and Group II – mature (number of teeth included = 10). The procedure was performed by the blood clot method as a scaffold. Biodentine (about 2–3 mm) was placed as a capping material at the cementoenamel junction. Evaluation was based on the clinical (pain, sinus, tender on percussion, swelling, mobility, intact restoration) and radiographical (Nolla stage, thickening of walls, lamina dura continuity, calcification of pulp chamber and canal, periapical healing, PAI score) parameters. All 19 teeth were clinically asymptomatic after the 12-month follow-up. Radiographically, the percentage of continuous root development (in the immature group) was 100% at 12 months (P = 0.000**). Radiography revealed a reduction in the PAI scores at 12 months in the immature and mature groups. None of the treated teeth responded to the cold test after a 12-month follow-up. One patient did not come for intervention in the mature group. All the statistical tests (Chi-square, Mann–Whitney U-test, and Fisher’s exact test) were performed at a 5% significance level. Outcomes did not differ significantly between immature and mature groups.
