Several treatment options have been proposed for restoring primary teeth in children. Recently, Zirconia crowns have been introduced as an esthetic option and gained wide popularity. However, the literature is still limited regarding the clinical outcomes and luting techniques of these crowns. The aim of this study was to compare the clinical efficacy of using Glass Ionomer Cement (GIC) versus self-adhesive resin cement with anterior zirconia crowns.
This was a split-mouth randomised clinical trial that involved healthy three-to-five-year-old children with carious primary incisors that required restoration with zirconia crowns. Pair-matched incisors were randomly assigned to receive either resin cement or GIC for crown cementation. Crowns were clinically evaluated for retention, and gingival condition at 1-week, 1-,3-, 6- and 12-month recall appointments.
Twenty-six children were enrolled in the study with a total of 42 pair-matched incisors (i.e. 84 teeth). Follow-up durations ranged from 12 to 30 months. Over the study period, only one patient experienced crown debonding in the GIC group. Maximum retention (100%) was reported for both GIC and resin cement groups after 12 months. Regarding gingival health, no statistically significant difference was found in the gingival index scores between the two cement types at all follow-up points.
The effect of the type of cement is likely to be clinically insignificant. GIC could be considered a valid alternative to the resin-based cement for zirconia crowns in primary teeth.
已提出多种治疗儿童乳牙修复的方法。最近，氧化锆全冠作为一种美观的修复选择被引入并广泛应用。然而，关于这些全冠的临床疗效和粘结技术的文献仍然有限。本研究的目的是比较使用玻璃离子水门汀（GIC）和自粘结树脂水门汀粘结前牙氧化锆全冠的临床疗效。
这是一项双侧随机临床试验，纳入了健康的3至5岁患有龋坏乳牙切牙且需要用氧化锆全冠修复的儿童。配对的切牙被随机分配接受树脂水门汀或GIC进行全冠粘结。在1周、1个月、3个月、6个月和12个月的复诊时，对全冠的固位情况和牙龈状况进行临床评估。
26名儿童参与了本研究，共有42对配对切牙（即84颗牙齿）。随访时间为12至30个月。在研究期间，GIC组只有1例患者出现全冠脱落。12个月后，GIC组和树脂水门汀组的固位率均达到最高（100%）。关于牙龈健康，在所有随访时间点，两种水门汀类型之间的牙龈指数评分均未发现统计学上的显著差异。
水门汀类型的影响在临床上可能不显著。GIC可被认为是乳牙氧化锆全冠粘结中树脂基水门汀的有效替代物。
