The aim of the study is to evaluate and compare the clinical and radiographic outcome of partial pulpotomy and full pulpotomy in mature permanent molars with symptomatic irreversible pulpitis using biodentine.
A total of 66 vital mature permanent molars with irreversible pulpitis were randomly allocated to a partial pulpotomy ( = 33) and full pulpotomy group ( = 33). Biodentine was used as a pulp capping material which was covered with resin-modified glass ionomer cement (RMGIC) followed by composite restoration. Clinical and radiographic evaluation was done at 3, 6, and 12 months follow-up for tenderness, periapical radiolucency, dentine bridge formation, and root canal calcification. Data from the study were analyzed using a Friedman and Mann-Whitney test and the success rate was analyzed by Chi-square value.
No statistically significant difference was found between partial and full pulpotomy ( > 0.05) and the success rate was 80.7% and 92.8%, respectively, at 12 months follow-up period.
Both partial and full pulpotomy can be used as a permanent treatment modality in symptomatic irreversible pulpitis of vital mature permanent molars.
本研究旨在评估和比较使用生物陶瓷在有症状的不可逆性牙髓炎的成熟恒牙中进行部分牙髓切断术和完全牙髓切断术的临床和影像学结果。
总共66颗患有不可逆性牙髓炎的活髓成熟恒牙被随机分配到部分牙髓切断术组（n = 33）和完全牙髓切断术组（n = 33）。生物陶瓷用作盖髓材料，其上覆盖树脂改性玻璃离子水门汀（RMGIC），然后进行复合树脂修复。在3、6和12个月的随访中对压痛、根尖透影区、牙本质桥形成和根管钙化进行临床和影像学评估。使用Friedman检验和Mann-Whitney检验分析研究数据，并通过卡方值分析成功率。
部分牙髓切断术和完全牙髓切断术之间未发现统计学上的显著差异（P > 0.05），在12个月的随访期内，成功率分别为80.7%和92.8%。
部分牙髓切断术和完全牙髓切断术均可作为有症状的活髓成熟恒牙不可逆性牙髓炎的永久性治疗方式。
