분광광도계를 이용한 상악 유전치부와 다양한 복합레진 색조의 비교

Abstract

The purpose of this study was to compare the color of maxillary primary central incisors, lateral incisors, canines with the color of various composite resins using a spectrophotometer VITA Easyshade®V. One researcher measured the color of sound maxillary primary anterior teeth of 100 children aged 1 to 6 and specimens which were made by composite resins with a total of 10 types and 31 shades, and CIE L*, a*, b* values were obtained. There was no clinically recognizable color difference between the maxillary primary central and lateral incisors. However, the maxillary primary canines showed difference in color above the clinical acceptability threshold with the primary central and lateral incisors. These findings showed no significant color differences between male and female, and no significant color changes with age. A1 shade is the most common in all maxillary primary anterior teeth. Composite resins, which are thought to be similar to the color of maxillary primary anterior teeth, were selected from 9 types of maxillary primary central incisors, 6 types of primary lateral incisors and 6 types of primary canines.
