Utilization of dental services and its relation to the periodontal status in a group of South Australian employees.

The pattern of dental service utilization, the perception of periodontal disease, and the oral hygiene habits among 642 industrial employees were evaluated using a self-administered questionnaire against background variables of age, sex, and socioeconomic strata. Of the study population, 50.5% had their most recent dental visit within the previous 12 months and 42.5% claimed to seek regular check ups. There was no significant association between time intervals since the last dental visit and age, sex, occupation, income or education. Regular visits were made more often by subjects in the higher occupation and income level. Multivariate analyses of the number of missing teeth simultaneously considering age, sex, socioeconomic level, regularity and frequency of dental visits revealed that except for age and sex, no other factors were significant. The most common reason for not seeing a dentist in the previous 12 months was an assumption that "nothing was wrong". A large majority of the group surveyed were unaware of the presence of periodontal disease or the need for its treatment, despite the high prevalence in all subgroups. Periodontal status was not significantly associated with sex, socioeconomic levels, regularity of frequency of dental visits, but there was a significant regression on age. The study population's pattern of service utilization was found to be similar to that reported for the general population, and it was anticipated that the hygiene habits of the group was representative of the total community. If that assumption is true the high prevalence of periodontal disease of the study population probably exists in the general community.
