Pulpotomy is a regular procedure in the management of inflamed primary teeth. Diverse materials have been reviewed for the pulpotomy, some of them being formocresol, glutaraldehyde, ferric sulfate, and mineral trioxide aggregate (MTA).
The aim was to evaluate and compare clinically and radiographically the effects of MTA as a pulp dressing after coronal pulp amputation (pulpotomy) in primary molars.
Sixty primary molars of thirty healthy children using split mouth design aged between 4 and 6 years were treated by pulpotomy technique.
Sixty primary mandibular molars of thirty healthy children aged between 4 and 6 years were treated by pulpotomy technique. The teeth on the right side were assigned to MTA (Group A) and the left side for the formocresol (Group B). The children were then examined clinically and radiographically every 6 months. Statistical analysis used: Chi-square test using the SPSS version 19.0 was used to compare between the two groups.
Results showed that both MTA and formocresol have the same outcome on the primary molars, with Chi-square value being 1.1483 ( ≥ 0.05). None of the teeth in any children in the study showed any clinical pathology.
The principle conclusions of this study are that there are no significant differences in MTA and formocresol. The success rate of MTA and formocresol pulpotomy can be considered comparable till this therapy influences the development and growth of the permanent teeth.
牙髓切断术是治疗乳磨牙牙髓炎症的常规方法。人们已对多种用于牙髓切断术的材料进行了评估,其中包括甲醛甲酚、戊二醛、硫酸铁和矿物三氧化物凝聚体(MTA)。
旨在通过临床和影像学评估及比较MTA作为乳牙冠髓切断术(牙髓切断术)后牙髓敷料的效果。
采用双盲设计,对30名年龄在4至6岁的健康儿童的60颗乳牙进行牙髓切断术治疗。
对30名年龄在4至6岁的健康儿童的60颗下颌乳磨牙采用牙髓切断术治疗。右侧牙齿分配给MTA组(A组),左侧牙齿分配给甲醛甲酚组(B组)。然后每6个月对儿童进行临床和影像学检查。统计分析方法:使用SPSS 19.0版进行卡方检验以比较两组。
结果显示,MTA和甲醛甲酚对乳磨牙的治疗效果相同,卡方值为1.1483(≥0.05)。研究中任何儿童的牙齿均未出现任何临床病变。
本研究的主要结论是,MTA和甲醛甲酚之间无显著差异。在该治疗方法影响恒牙的发育和生长之前,MTA和甲醛甲酚牙髓切断术的成功率可认为相当。
