To evaluate in vitro and in vivo conditions of stainless steel crowns (SSC) cemented using one luting glass-ionomer cement (Aqua Meron) and one luting resin-modified glass-ionomer cement (Vitremer).
In the in vitro part of this study, retentive properties of SSCs cemented using Aqua Meron and Vitremer on extracted primary first molars were tested. In addition, two specimens of each group were used to evaluate the tooth hard tissue-cement, within the cement itself, cement-SSC, and tooth hard tissue-cement-SSC under scanning electron microscope (SEM). In the in vivo part of this study, 152 SSCs were placed on the first or second primary molars of 86 children, and cemented using either Aqua Meron or Vitremer. The crowns were examined for retention. In addition, the clinical views of the crowns were recorded with an intraoral camera.
No significant difference was found between the mean retentive forces of Aqua Meron and Vitremer (P> 0.05). SSCs cemented with Aqua Meron and Vitremer had an average lifespan of 26.44 and 24.07 months respectively. Only one (0.66%) of 152 SSCs was lost from the Aqua Meron group during post-cementation periods. Nineteen of the 152 SSCs (12.5%) had dents or perforations.
评估使用一种玻璃离子水门汀（Aqua Meron）和一种树脂改性玻璃离子水门汀（Vitremer）粘结的不锈钢冠（SSC）的体外和体内情况。
在本研究的体外部分，测试了使用Aqua Meron和Vitremer粘结在拔除的乳牙第一磨牙上的SSC的固位性能。此外，每组使用两个样本，在扫描电子显微镜（SEM）下评估牙齿硬组织 - 水门汀、水门汀本身、水门汀 - SSC以及牙齿硬组织 - 水门汀 - SSC的情况。在本研究的体内部分，将152个SSC放置在86名儿童的第一或第二乳磨牙上，并使用Aqua Meron或Vitremer进行粘结。检查冠的固位情况。此外，用口腔内摄像头记录冠的临床情况。
Aqua Meron和Vitremer的平均固位力之间未发现显著差异（P>0.05）。用Aqua Meron和Vitremer粘结的SSC的平均使用寿命分别为26.44个月和24.07个月。在粘结后期间，Aqua Meron组的152个SSC中仅有一个（0.66%）脱落。152个SSC中有19个（12.5%）有凹痕或穿孔。
