目的

通过观察和对比深龋露髓的年轻恒牙应用iRoot BP Plus和矿物三氧化聚合体(MTA)直接盖髓的远期临床疗效,探讨iRoot BP Plus在年轻恒牙盖髓治疗上的优越性。

方法

对7~ 15岁患者的30颗年轻、深龋露髓患牙(包括去腐露髓和意外露髓的年轻恒牙),随机分为iRoot BP Plus组和MTA组,每组各15颗,分别行iRoot BP Plus和MTA直接盖髓术,随访2组1年内的临床疗效(包括牙髓症状、牙髓活力、钙化桥的形成和根尖孔闭合),对比分析2组钙化桥形成率和直接盖髓成功率,百分率统计采用秩和检验,两者盖髓时间统计采用独立样本t检验。

结果

术后1年,iRoot BP Plus组和MTA组治疗成功率分别为86.7%和80.0%,组间差异无统计学意义(χ2= 0.240,P= 0.624);而2组直接盖髓操作时间分别为(2.55 ± 0.33)和(4.88 ± 0.25)min,差异有统计学意义(t=-21.983,P<0.001);iRoot BP Plus组盖髓就诊次数少于MTA组,iRoot BP Plus组和MTA组术后随访3个月X线完整钙化桥形成率为80.0%和73.3%(χ2= 0.186,P= 0.666),6个月形成率分别为86.7%和80.0%(χ2= 0.240,P= 0.624),12个月形成率分别为86.7%和80.0%(χ2= 0.240,P= 0.624),组间差异均无统计学意义。iRoot BP Plus组患牙未见牙齿变色,MTA组患牙均观察到牙齿变色现象。

结论

iRoot BP Plus直接盖髓的临床疗效与MTA相近,但iRoot BP Plus操作较为便利、就诊次数少且无牙齿变色现象,是临床上更为理想的直接盖髓剂。

Objective

To observe and compare the clinical efficacy of direct pulp capping with iRoot BP Plus and mineral trioxide aggregate (MTA) in young permanent teeth with deep caries and exposed pulp.

Methods

Thirty young permanent teeth in 7- to 15-year-old patients, were randomly divided into iRoot BP Plus group (fifteen teeth) and MTA group (fifteen teeth) . iRoot BP Plus and MTA were used to direct cap on the exposed pulp. Clinical symptoms, pulp vitality, the formation of dentinal bridge, and the closing of the rupture of teeth marrow were evaluated in 1 year. The percentage of root canal calcification bridges formation and the survival rate of the pulp were compared and evaluated by Wilcoxon rank sum test. And Student′s t test was used for the statistical analysis of the operation time of capping.

Results

After 1 year, the survival rate of the pulp in iRoot BP Plus group was 86.7%, which was 80.0% in MTA group, while there was no significant difference between two group (χ2= 0.240, P= 0.624) . The operation time of capping in iRoot BP Plus group and MTA group were (2.55 ± 0.33) min and (4.88 ± 0.25) min. Thus, the operation time of capping in iRoot BP Plus group was significantly shorter than MTA group (t=-21.983, P<0.001) . The times of visit of iRoot BP Plus group was less than MTA group in this study. After 3 months of follow-up, the rate of calcification formation in iRoot BP plus group and MTA group were respectively 80% and 73.3% (χ2= 0.186, P= 0.666) . After 6 months, the formation rates were 86.7% and 80% (χ2= 0.240, P= 0.624) , respectively, and after 12 months the formation rates were 86.7% and 80% (χ2= 0.240, P= 0.624) , respectively. There was no significant difference for the rate of calcification formation between the two groups. The teeth were discolored in the MTA group, and no tooth discoloration occurred in the iRoot BP Plus group.

Conclusions

Both iRoot BP Plus and MTA are excellent direct pulp capping agents. The clinical effect of iRoot BP Plus is similar to MTA. The operation of direct pulp capping with iRoot BP Plus is quicker and easier than MTA.
