Abstract

결 론
조선대학교 치과대학 부속치과병원 소아치과에 내원한 3∼6세의 소아 20명(남 12명, 여 8
명)을 대상으로 OFC-1001 DP colorimeter를 이용해 상악 우측 유중절치, 유견치, 제2유구치
의 절단부, 중앙부, 치경부 등 3부분으로 나누어 유치의 치아색을 측정한 결과 다음과 같은
결론을 얻었다.
1. 전체 치아의 명도(L), 적색채도(a), 황색채도(b)의 평균치, 최대·최소치를 구하였다.
(Table 2, 3, 4)
2. 한국인 유치의 치아색은 청회색(bluish gray) 혹은 청녹회색 (bluish-green gray)을 보
였다.
3. 상악 유중절치와 유견치가 상악제2유구치에 비해 명도(L)가 높다.
4. 상악 유중절치가 유견치나 제2유구치에 비해 치경부에서는 적색채도(a)가 더 높으며,
절단부에서는 황색채도가 더 높다.
5. 유견치와 제2유구치에서 명도(L)는 치경부로 갈수록 높다.
6. 유치의 적색채도(a)는 각 부위에 따라 차이가 없었으나, 황색채도(b)는 절단부에서 가
장 낮고, 치경부로 갈수록 높다.
#초록#
The purpose of this study was to analyze the color of the Korean natural deciduous
teeth by means of the OFC-1001 DP colorimeter which could measure in Adams
Coordinate System(L, a, b system).
The subjects were the 20 children (12 boys and 8 girls), aged from three to six year,
who had come to infirmary of dental college, Chosun University. The colors of incisal
third, middle third and cervical third of maxillary right deciduous incisor, canine and
second molor were examined after the teeth were cleaned and dried. The data were
analyzed statistically by means of SPSS(Statistical Package for the Social Science).
The results were as follows:
1. The means of L (lightness), a (red chromaticity) and b (yellow chromaticity) of all
teeth were measured (Table 2, 3, 4).
2. The color of Korean deciduous teeth was bluish gray or bluish-green gray.
3. The L values of the maxillary right deciduous incisor and canine were greater than
that of maxillary right deciduous second motor.
4. In cervical third, the a value of the maxillary right deciduous incisor was greater
than those of the maxillary right deciduous canine and second molor. In incisal third, the
b value of the maxillary right deciduous canine and second molor.
5. The L values of the cervical third and middle third were greater than that of
incisal third in maxillary right deciduous canine and second molor.
6. The avarage value of a according to region of each tooth were not significant, but
the b value of the cervical third was greater than those of the incisal & middle third in
maxillary right deciduous teeth.
