A study on relationship between subjective periodontal health status and objective periodontal index among adult
성인의 주관적 치주상태와 객관적 치주지수와의 관련성
The aim of the study was to confirm the relation of subjective periodontal
symptoms to objective periodontal index by comparing personal periodontal
evaluation and actualoral health examed in the dental office.
Two hundred and fifteen outpatients were selected for this study and
confirmed by Institutional Review Board in Ajou UniversityHospital. They
were surveyed by confirmed questionnaire and examined forcommunity
In the study, the independent variables include general demographic data,
oral health behaviors, subjective perceptions, and experiences with treating
a systematic or periodontal disease, and the dependent ones include
subjective periodontal symptoms and objective periodontal index. The
revised and supplemented questionnaire was confirmed for reliability and
validity. Statistical treatment methods employed in the study were descriptive statistics for each variable, cross-tabulation to check differences between variables, simple correlation analysis for relation between subjective periodontal symptoms and objective periodontal index, and simple linear regression analysis to check the effects of the independent variables on the dependent ones.
The high age group and the dental treatment group showed common
symptoms, "food impaction" and "toothmobility". The lower age group, no
recent treatment group(1year), no scaling group, and the no regular
check-up group were all aware of "presence of calculus" inside the mouth.
CPI was relatively high in the high age group and tooth extraction group.
No scaling group recorded a relatively higher CPI than scaling group. CPI
was relatively high among those who had hypertension or diabetes. The
more negative perceptions they had of their toothbrushing, the lower their
CPI had positive(+) correlations with subjective periodontal statuses such as bleeding on toothbrushing, food impaction, gingival pain, tooth mobility,
gingival swelling, and the degree of tooth malposition(p<.05,p<.01).
Conclusively, there were many corresponding but not the same aspects
between subjective symptoms and objective periodontal index, which
