This retrospective study analyzed the 12-month pulp sensibility (cold and electric) test response after mineral trioxide aggregate (MTA) full pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis.
The records of 120 subjects from 3 completed and 1 ongoing clinical study on MTA full pulpotomy were retrieved. Ninety-six first and second mandibular molar teeth with a diagnosis of symptomatic irreversible pulpitis that underwent a single-visit MTA full pulpotomy and had completed a 12-month clinical, radiographic, and pulp sensibility (cold and electric) test follow-up were included. The data were analyzed using the Fisher exact test, the Pearson chi-square test, and the McNemar test. The significance level was predetermined at P < .05.
A higher percentage of teeth (94.7%) responded to the electric pulp test in comparison with the cold test (13.5%) (P < .05). Sex-based responses to the electric pulp test (P > .05) and the cold test were similar (P > .05). The age-based response was similar for the electric pulp test (P > .05) but was significant for the cold test (P < .05). The tooth quadrant (left and right), the tooth (mandibular first and second molar), and the location of restoration (proximal or occlusal) did not influence the response of either the electric pulp test (P > .05) or the cold test (P > .05). At the 1-year follow-up, all the teeth that were classified as clinically and radiographically successful responded to the electric pulp test; however, only 13 teeth responded to the cold test (P = .00).
The majority (94.7%) of the teeth that underwent MTA full pulpotomy responded to the electric pulp test at a 1-year time interval.
本回顾性研究分析了有症状不可复性牙髓炎的成熟恒牙行矿化三氧化物聚合体（MTA）全牙髓切断术后 12 个月牙髓活力（冷、电测试）的反应。
从 3 项已完成和 1 项正在进行的关于 MTA 全牙髓切断术的临床研究中提取了 120 名受试者的记录。纳入 96 例第一、第二下颌磨牙，诊断为有症状不可复性牙髓炎，单次就诊行 MTA 全牙髓切断术，并完成了 12 个月的临床、放射学和牙髓活力（冷、电测试）随访。采用 Fisher 确切检验、Pearson 卡方检验和 McNemar 检验进行数据分析。预设显著性水平为 P<.05。
与冷测试（13.5%）相比，电测试的牙齿（94.7%）反应更高（P<.05）。电测试的性别反应（P>.05）和冷测试相似（P>.05）。电测试的年龄反应相似（P>.05），但冷测试的年龄反应显著（P<.05）。电测试的牙位（左侧和右侧）、牙位（下颌第一和第二磨牙）和修复位置（近中或咬合面）不影响电测试（P>.05）或冷测试（P>.05）的反应。在 1 年的随访中，所有临床和放射学上成功的牙齿都对电测试有反应，但只有 13 颗牙齿对冷测试有反应（P=.00）。
在 1 年的时间间隔内，行 MTA 全牙髓切断术的大多数（94.7%）牙齿对电测试有反应。
