The purpose of this retrospective study was to evaluate pulpotomies completed without the use of a fixative, preservative, or astringent agent prior to placement of a reinforced zinc oxide-eugenol (ZOE) sub-base in the pulp chamber and subsequent restoration.
Clinical and radiographic data were collected from a private pediatric dental office in Toronto, Ontario, Canada. The pulpotomy technique used involved: amputation of coronal pulp; radicular hemostasis via pressure with dry cotton pellet; placement of ZOE into the pulp chamber; and restoration with stainless steel crown or amalgam.
One-hundred-ninety primary molars in 116 children (follow-up=6-94 months; mean=35.8 months) met the inclusion criteria. The radiographic, clinical, and overall success rates were approximately 95%, 97%, and 94%, respectively. The most frequently observed pathologic pulpal response was furcation radiolucency (N=7, ∼4%). The patient's age at time of pulpotomy, restoration type, tooth type, arch, and location of treatment (in-office vs general anesthesia) were not statistically significant factors influencing the success of the reinforced ZOE pulpotomy technique.
The success rates indicate that the reinforced zinc oxide-eugenol pulpotomy technique may be an acceptable treatment modality for primary molars requiring vital pulp therapy.
本回顾性研究的目的是评估在牙髓腔中放置增强型氧化锌丁香油(ZOE)衬层并进行后续修复之前,不使用固定剂、防腐剂或收敛剂完成的牙髓切断术。
从加拿大安大略省多伦多市的一家私人儿科牙科诊所收集临床和影像学数据。所采用的牙髓切断术技术包括:切除冠髓;用干棉球压迫进行根管止血;将ZOE放入牙髓腔;以及用不锈钢冠或银汞合金进行修复。
116名儿童的190颗乳磨牙(随访时间=6 - 94个月;平均=35.8个月)符合纳入标准。影像学成功率、临床成功率和总体成功率分别约为95%、97%和94%。最常观察到的牙髓病理反应是根分叉透射区(N = 7,约4%)。牙髓切断术时患者的年龄、修复类型、牙齿类型、牙弓以及治疗地点(诊所内治疗与全身麻醉)并非影响增强型ZOE牙髓切断术技术成功的统计学显著因素。
成功率表明,增强型氧化锌丁香油牙髓切断术技术对于需要进行活髓治疗的乳磨牙可能是一种可接受的治疗方式。
