Conceptions of Finnish people about their periodontal situation.

The conceptions of Finns regarding their own periodontal status were surveyed in 1972. The interviewed sample, drawn to cover the total Finnish population aged 15 years and over, comprised 965 persons. After exclusion of 233 edentulous subjects, a total of 732 dentulous persons were accepted for the present interview study. 10 percent of the interviewees were aware of their having gingivitis at that time. 57 percent were of the opinion that they had never had gingivitis. On the other hand, 20 percent of the interviewed persons had recently observed gum bleeding while 54 percent stated that they had never observed it. 21 percent of the interviewees were aware of their having dental calculus and 46 percent had the impression that they had never had calculus. 24 oercent of those interviewees who presently had calculus or had had calculus stated that they had never had it removed. Generally Finns failed to realize that gingival bleeding is a symptom of gingival inflammation. This point should be made clear in the dental health education of the future. The knowledge could help individuals to evaluate the state of their own periodontal tissues in order to obtain the best possible benefit from efficient home care.
