Abstract:
Objective
The situation of oral health knowledge as well as the main oral hygiene problems of the middle aged and elder people in Guangzhou urban and suburb communities was evaluated utilizing questionnaire tests. The differences in periodontal health between urban and suburb communities were compared by community periodontal index （CPI）. Furthermore， the related factors affect tested people on periodontal health were analyzed.
Methods
Six hundred middle aged and elder people （ages ranged from 35 to 74） were randomly selected from Guangzhou urban and suburb communities as the subjects utilizing the multi-stage capacity stochastic method， gender ratio approximate 1 ∶1. Questionnaire survey was conducted， and CPI code was got using CPI probe.
Results
According to questionnaire results， 68.1% subjects in urban and suburb groups brushed no less than twice per day with an incidence of gingival bleeding （Spontaneous， brush or chew） of 53.0%， and only 2.4% of the subjects used floss， interdental brush or water pick. Comparing the results between urban and suburb groups， 50.4% of the urban subjects were submitted to scaling， while the percentage dropped to 29.1% for suburb group （χ2=26.026， P＜0.001）. The results show that the CPI code X （S）of urban groups is 3.35 （1.54）， and the suburb groups is 3.70 （1.71）. It shows statistical significant difference between the two groups （t=-2.533， P=0.012）. 50.5% of the subjects demonstrated a CPI code 3， 22.0% subjects showed a CPI code 4. Based on logistic regression analysis， the gender， age，education degree and state of gingival bleeding （Spontaneous， brush or chew） were significantly associated with the severity of periodontal disease.
Conclusions
Middle aged and elder people in Guangzhou urban and suburb communities demonstrate a high incidence of periodontal disease with relatively weak oral hygiene awareness. Gender， age， education degree and state of gingival bleeding（Spontaneous， brush or chew） are relative with the severity of periodontitis on middle aged and elder people in Guangzhou urban and suburb communities.
