Abstract

Purpose: The purpose of this study was to compare one-year clinical outcomes of primary incisor strip crowns (SCs) and zirconia crowns (ZCs) and determine the frequency of pulp therapy associated with each technique.

Methods: Children aged 18 to 48 months were randomly assigned to a ZC group or SC group. Each incisor was rated as intact (I), damaged (D), or requiring treatment (TR) six and 12 months following placement.

Results: Seventy-six ZCs and 101 SCs were placed for 59 participants; ZCs were more likely to be rated I than SCs at six months (odds ratio [OR] equals 4.2; P=0.01) and 12 months (OR equals 4.0; P=0.02). There was no statistical difference in the frequency of pulp therapy between groups (OR equals 0.8; P=0.70). There were no deviations from treatment randomization in either group.

Conclusions: Zirconia crowns were more likely than strip crowns to be rated as intact at six or 12 months after treatment. The frequency of pulp therapy was not statistically different between groups.

上颌切牙氧化锆与复合树脂条冠的比较:为期一年的可行性研究。

目的:本研究的目的是比较初级切牙条带冠(SCs)和氧化锆冠(ZCs)一年的临床结果，并确定每种技术的牙髓治疗频率。方法:将18 ~ 48月龄儿童随机分为ZC组和SC组。每个门牙在放置6个月和12个月后被评为完好(I)，受损(D)或需要治疗(TR)。结果:59名受试者放置了76个zc和101个SCs;6个月时，ZCs比SCs更有可能被评为I级(比值比[OR] = 4.2;P=0.01)和12个月(OR = 4.0;P = 0.02)。两组间牙髓治疗频率差异无统计学意义(OR = 0.8;P = 0.70)。两组均未出现治疗随机化的偏差。结论:在治疗后6个月或12个月，氧化锆冠比带状冠更有可能被评为完整。组间牙髓治疗频率无统计学差异。
