The anatomical pits and fissures of the teeth have long been recognized as susceptible areas for the initiation of dental caries. The extreme vulnerability to decay of these pits and fissures on the occlusal surfaces has prompted dental scientists to seek methods of caries prevention. Motivated by the role of pit and fissure sealants in caries prevention, the aim of this study was to compare the efficacy of Fuji VII glass ionomer sealant and Concise resin-based sealant.
An in vitro study was undertaken using forty premolars extracted for orthodontic reasons. The teeth were divided into two groups and sealants were applied. One was an experimental group using Fuji VII as a pit and fissure sealant and the other a control group using Concise. The teeth were kept in gentian violet dye for 24 hours, the sectioned samples were observed for the extent of dye penetration, and scores were based on established scoring criteria.
The comparison of the performance of the two groups showed a statistically significant difference.
The Concise resin-based sealant performed better in terms of sealing ability than did the Fuji VII glass ionomer sealant.
牙齿的解剖窝沟长期以来一直被认为是龋齿始发的易感区域。咬合面上这些窝沟对龋齿的极端易感性促使牙科科学家寻求预防龋齿的方法。受窝沟封闭剂在预防龋齿中作用的启发,本研究的目的是比较富士VII玻璃离子封闭剂和Concise树脂基封闭剂的疗效。
使用因正畸原因拔除的40颗前磨牙进行体外研究。将牙齿分为两组并应用封闭剂。一组为实验组,使用富士VII作为窝沟封闭剂,另一组为对照组,使用Concise。将牙齿置于龙胆紫染料中24小时,观察切片样本中染料渗透的程度,并根据既定的评分标准进行评分。
两组性能的比较显示出统计学上的显著差异。
Concise树脂基封闭剂在封闭能力方面比富士VII玻璃离子封闭剂表现更好。
