Study on the effect of esthetic improvement using the dental coating materials

应用于牙体的涂层材料和修复材料表面作为一种选择来平衡感官获得和MI：存在最小的干预。然而，指导在临床方面的情况尚不明确。本研究旨在从不同角度考察牙膜材料在体外的感官改善效果和耐久性，为临床应用的证据构建奠定基础。结果表明，从各种食品中提取的色素对复合树脂本身的着色有一定的影响，其着色被增白剂破坏，再涂覆后着色效果减弱。此外，对于着色程度，认识到填料在复合树脂中组合的体积比有影响的趋势。

Coating materials applying to the tooth substance and restoration materials surface as one choice to balance sensuousness acquisition with MI: Minimal Intervention exist.However, the guidance at the clinical situation has not yet clear. The purpose of this study aims at the foundation of the Evidence construction for clinical applications by examining the sensuousness improvement effect of dental coating materials and the durability in in vitro from different angles.As a result, the pigment derived from various kinds of food influenced the coloration to composite resin in itself, and it was revealed the coloration being broken by a whitening agent, that a coloration effect attenuated by coating again.In addition, as for the degree of the coloration, a tendency to be affected by the volume ratio of fillers combined in composite resin was recognized.
