Abstract
결론
치아색에 이상이 없고, 전신적인 병력이 없는, 3∼15세의 소아 90명(유치 60명, 영구치 30
명)을 대상으로 OFC -1001 DP Colorimeter를 이용하여, 유치 및 영구치의 치관부 절단
1/3, 중앙 1/3, 치경 1/3등 3부분으로 나누어 치아의 색을 측정한 결과, 다음과 같은 결론을
얻었다.
1. 유치의 명도(L), 적색채도(a), 황색채도(b)의 평균, 최대 및 최소치를 구하였다.
2. 한국인 유치의 치아색은 청회색(bluish gray) 혹은 청녹회색(bluish-geen gay)을 보였다.
3. 유치의 명도(L)는 전치부가 구치부보다 높고, 적색채도(a) 및 황색채도(b)는 중절치가 가
장 높았다.
4. 치아의 각 부위에 따른 명도(L), 적색채도(a), 황색채도(b)는 절단부로 갈수록 높았다.
5. 남녀간에 명도(L), 적색채도(a), 황색채도(b) 모두 유의차가 없었다.
6. 증령에 따라 명도(L)는 약간 감소하는 경향을 보이나, 적색채도(a)와 황색채도(b)는 약간
증가하는 경향을 보였으며, 상관관계는 아주 약한 상관관계를 보였다.
7. 유치와 영구치를 비교시 명도(L)는 유치가 높았고, 적색채도(a)는 영구치가 높았으며, 황
색채도(b)는 차이가 없었다.
#초록#
The purpose of this study was to analyse the color of the natural deciduous teeth in
Korean children by means of the OPC -1001 DP Colorimeter which can be measured by
Adams coordinate system (L, a, b system).
The subjects were 90 children (43 boys and 47 girls) with good general condition and
normal tooth color, aged from three to fifteen year. The color of incisal third, middle
third, and cervical third of maxillary right central incisor, canine, and second molar in
deciduous teeth and maxillary right central incisor, canine, and second premolar in
permanent teeth were examined after the teeth were cleaned and dried.
The data were analysed statistically by means of SPSS(Statistical Package for the
Social Sciences) on Prime 750 Computer.
The results were as follows :
1. The mean of L(lightness), a (red chromaticity), and b (yellow chromaticity) of
deciduous teeth were measured.
2. The color of Korean deciduous teeth was bluish gray or bluish-green gray,
3. The L value of anterior teeth was greater than that of posterior teeth and the
incisor was greater than other teeth in the a and b values.
4. The L, a, and b values of incisal third were greater than those of the cervical third.
5. The average L, a, and b values of deciduous teeth were not statistically significant
differences between sex groups.
6. The age being increased, the L value of deciduous teeth was slightly decreased but
the a and b values of deciduous teeth were slightly increased.
7. The L value of deciduous teeth was greater and the a value of deciduous teeth was
smaller than that of permanent teeth, but the b values were not statistically significant
diflerences between dentition groups.
