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.
