The purpose of this study was to assess the outcome of coronal pulpotomy using mineral trioxide aggregate (MTA) in mature and immature teeth with symptoms indicative of irreversible pulpitis.
Fifty permanent molars with symptomatic irreversible pulpitis were divided into two groups according to complete or incomplete radicular growth (25 teeth in each group). Coronal pulpotomy was performed with MTA. Clinical follow-up evaluations were scheduled at the third, sixth, ninth, 12th, 18th, and 24th months. Follow-up radiographs were taken at the sixth, 12th, 18th, and 24th months. Pain levels were scored preoperatively and two days post-treatment.
At two years of recall, 10 patients were lost to follow-up and the success of molars with complete or incomplete radicular growth were 100 percent and 95 percent, respectively. All teeth with periapical rarefaction were present preoperatively and showed complete radiographic healing. Radiographic evidence of dentin bridge formation was discernable in 31 of 38 cases.
Full coronal pulpotomy using mineral trioxide aggregate was successful in controlling pain and any infections after two years in 39 of 40 teeth regardless of whether they had immature or mature roots.
本研究旨在评估使用三氧化矿物凝聚体（MTA）对有不可逆性牙髓炎症状的成熟恒牙和年轻恒牙进行冠髓切断术的疗效。
根据根方完全或不完全发育（每组 25 颗牙），将 50 颗有症状的不可逆性牙髓炎的恒牙分为两组。使用 MTA 进行冠髓切断术。临床随访评估分别在第 3、6、9、12、18 和 24 个月进行。在第 6、12、18 和 24 个月时拍摄随访 X 线片。术前和治疗后两天记录疼痛程度。
在 2 年的随访中，10 名患者失访，根方完全发育和不完全发育的磨牙成功率分别为 100%和 95%。所有术前存在根尖稀疏的牙齿均完全愈合。在 38 例中有 31 例可识别出牙本质桥形成的放射学证据。
在 2 年的随访中，40 颗牙中的 39 颗（无论其根方是否发育成熟）均成功地使用 MTA 进行完全冠髓切断术，控制了疼痛和任何感染。
