This prospective clinical study evaluated the success of vital pulpotomy treatment for permanent teeth with closed apices using mineral trioxide aggregates (MTA) in a dental public health setting.
Twenty-seven mature permanent first molars and 2 premolars (in 25 patients) with carious exposure were treated using MTA pulpotomy. Age of patients ranged from 10- to 15-years (mean=13.2±1.74-years). Four trained and calibrated practitioners performed the same clinical procedure for all patients. Following isolation and caries removal, the inflamed pulp tissue was completely removed from the pulp chamber. This was followed by irrigation with 2% sodium hypochlorite. Haemostasis was achieved using a cotton pellet damped in normal saline. A white MTA paste was placed against the pulp orifices. MTA was covered with a damped cotton pellet and a base of IRM. Patients were recalled after 1 day where a glass ionomer liner and a final restoration were placed. Teeth were evaluated clinically and radiographically for up to 47 months.
Mean follow-up period for all teeth was 25±14 months. Twenty-six of the 29 teeth were clinically asymptomatic with no evidence of periradicular or root pathology during the follow-up period. The estimated success rate was 90%. Three teeth presented with clinical symptoms of pain and radiographic evidence of periradicular pathology that indicated root canal treatment (RCT) or extraction.
When managing carious pulp exposures of permanent teeth with closed root apices in children, MTA pulpotomy showed a high success rate.
MTA pulpotomy for permanent molars in children is a viable alternative to RCT.
本前瞻性临床研究评估了在牙科公共卫生环境中,使用三氧化矿物凝聚体(MTA)对根尖封闭的恒牙进行活髓切断术治疗的成功率。
对25例患者的27颗成熟恒牙第一磨牙和2颗前磨牙进行龋洞暴露处理,并采用MTA活髓切断术。患者年龄在10至15岁之间(平均=13.2±1.74岁)。四名经过培训和校准的从业者对所有患者进行相同的临床操作。在隔离和去除龋坏组织后,将发炎的牙髓组织从髓腔中完全清除。随后用2%的次氯酸钠冲洗。使用浸有生理盐水的棉球止血。将白色MTA糊剂放置在髓孔处。MTA上覆盖浸有生理盐水的棉球和IRM垫底材料。1天后召回患者,放置玻璃离子粘固剂衬层和最终修复体。对牙齿进行临床和影像学评估,最长达47个月。
所有牙齿的平均随访期为25±14个月。29颗牙齿中有26颗在随访期间临床无症状,无根尖周或牙根病变的证据。估计成功率为90%。三颗牙齿出现疼痛的临床症状和根尖周病变的影像学证据,表明需要进行根管治疗(RCT)或拔除。
在处理儿童根尖封闭的恒牙龋源性牙髓暴露时,MTA活髓切断术显示出较高的成功率。
儿童恒牙MTA活髓切断术是RCT的可行替代方法。
