저자는 Y대 치과병원 치주과를 내원한 환자와 대도시에서 조사한 일반인 간에 치주낭 깊이, 치은퇴축과 각화치은의 넓이에 있어 차이가 있는지를 알기위해서 Y대 치과병원 치주과를 내원한 초진환자 353명과 대도시에서 조사한 일반인 353명을 조사대상으로 하여 치주낭 깊이, 치은퇴축, 각화치은의 넓이를 조사하여 비교하였다.

치주낭 깊이와 치은퇴축, 각화치은의 넓이는 Williams probe를 이용하여 측정 하였으며 얻어진 자료를 SPSS 프로그램중 T-test를 이용하여, 통계처리 및 비교분석하여 다음과 같은 결론을 얻었다.

1. 치주낭 깊이는 병원환자와 일반인의 평균값이 각각 3.21 ± 1.25mm, 2.52 ± 0.60mm 이었으며, 집단간에 유의성있는 차이가 있었다. (P<0.01)

2. 치주낭이 가장 깊은 부위는 상악구치 부위였으며, 병원환자의 경우는 3.96 ± 1.75mm 이었고, 일반인 경우에는 2.92 ± 0.77mm 이었다.

3. 치은퇴축은 병원환자와 일반인의 평균값이 각각 0.09 ± 0.47mm, 0.22 ± 0.50mm 이었으며, 상하악 소구치, 상악구치, 하악전치 부위에서 집단간의 유의성있는 차이가 있었다. (P< 0.01)

4. 치은퇴축 발생 빈도는 병뭔 환자에서 하악 전치부에서 ( 6.8%) 제일 빈도가 컸으며, 일반인에서는 상악 제 1소구치에서 ( 21.2%) 제일 큰 빈도를 나타냈다.

5. 각화치은의 넓이는 병원환자와 일반인의 평균값이 각각 3.92 ± 0.78mm, 3.88 ± 0.81mm 이었으며, 집단간에 유의성있는 차이가 없었다.

A STATISTICAL STUDY ON THE STATUS OF PERIODONTAL TISSUES BETWEEN PATIENTS AND

PERSONS WITHOUT CHIEF COMPLAINT

Seong Ho Choi, D.D.S.

Department of Dental Science, Graduate School, Yonsei University

(Directed by Prof. Chong Kwan Kim D.D.S., M.S.D., Ph.D.)

The purpose of this study was to compare the status of periodontal tissues

between patients and persons without chief complaint.

706 subjects were selected for this study. The subjects were divided into two

groups: A group; 353 patients in a dental hospital. B group; 353 individuals from

large cities surveyed.

The pocket depth, gingival recession, and the width of keratinized gingival were

examined in each tooth and arch to compare A and B group and then the comparison

between A and B group was performed with T-test.

The results were as follows:

1. In the periodontal pocket, there was statistically significant difference in

the relationship between A and B group.(P< 0.01) The mean value of A group(3.21 ±

1.25mm) was deeper than that of B group (2.52 ± 0.60mm).

2. The deepest pocket depth of A group was seen in the upper 2nd molar (3.96 ±

1.75mm) and the same phenomenum was seen in B group (2.92 ± 0.78mm).

3. In the gingival recession, there was statistically significant difference in

the upper premolar and molar, and lower anterior teeth and premolar of A and B

group. (P < 0.01) The mean value of B group (0.22 ± 0.50mm) was more than that of

A goup (0.09 ± 0.47mm).

4. In the gingival recession, the most prevalence was seen in the lower anterior

teeth of A group (6.8%), and in the upper 1st premolar of B group (21.2%).

5. In the keratinized gingiva, there was no statistically significant difference

in the A and B group. The mean value of A group was 3.92 ± 0.79mm and that of B

group was 3.88 ± 0.81 mm.
