상·하악전치부의 근관치료에 사용되는 시술길이(Working Length)에 관한 통계학적 연구

Abstract

[한글]

저자는 1978년 2월부터 1984년 6월까지 연세대학교 치과대학부속병원 보존과에 내원한 환자중에서 상·하악전치부 근관치료를 받은 827명의 1249개 치아를 대상으로 치아별, 성별. 연령별에 따라 근관충전을 위해 측정된 근관길이를 조사하여 다음과 같은 결과를 얻었다.

1. 상·하악전치부외 평균근관길이는 다음과 같다.

상악중절치 : 21.8mm

상악측절치 : 21.0mm

상 악 견 치 : 24.lmm

하악중절치 : 18.6mm

하라측절치 : 19.9mm

하 악 견 치 : 22.6mm

2. 각 치아에서 성별에 따른 근관길이의 차이는 통계적으로 유의차가 없었다. (P>0.05)

3. 각 치아에서 연령에 따른 근관길이의 차이는 통계적으로 유의차가 없었다. (P>0.05)

4. 연령별 분포로는 10대-40대에서는 상악중절치, 상악측절치, 하악중절치순으로 많았고 그외 연령층에서는 각 치아간에 별다른 차이는 볼 수 없었다.

성별 분포로는 남자가 49.5%, 여자가 50.4%로 유사하게 나타났으며, 상·하악별로는 상악이 74.3%, 하악이 25.7% 였고 그중에서 상악중절치가 40.6%로 전체의 1/2가량을 차지했다.

A STATISTICAL STUDY ON WORKING LENGTH OF UPPER AND LOWER ANTERIOR TEETH IN

ENDODONTIC TREATMENT

Department of Dental Science, Graduate School, Yonsei Unoversity

(Directed by Assistant Prof. Dong Soo Park, D.D.S.,M.S.D.,Ph.D)

This study was based upon 827 out-patients who's upper & lower anterior teeth bad

endodontic treatment at the operative department of Yonsei University Dental

College from Feb.1978 to June 1984. The 1249 teeth of these patients were devided

into sex and age groups. The root canal length of these teeth were measured.

The following results were obtained ;

1. The mean root canal length of upper & lower anterior teeth were as follows;

Upper central incisors : 21.8mm

Upper lateral incisors : 21.0mm

Upper canines : 24.1mm

Lower central incisors : 18.6mm

Lower lateral incisors : 19.9mm

Lower canines : 22.6mm

2. There was no significant difference in root canal length between sex. (p>0.01)

3. There was no significant difference in root canal length between age group.

(p>0.05)

4. The distribution of upper central incisors showed the highest distribution

followed by upper lateral incisors and lower central incisors between 10 to 40 year

old age groups, and there was no significant difference in the rest of the age

groups.

There was no significant difference in sex distribution, which was 49.5% for

males and 50.4% for females. The number of the upper anterior teeth was 74.3% of

all the specimens and the lower anterior 25.7%, and 40.6% of all the specimens were

upper central incisors.
