[Further results from the Berlin morbidity study of 1972. 1. Educational level, knowledge of dental health and oral hygiene].

There are relationships between the general educational level and the extent of dental health knowledge on the one hand, and between the dental health knowledge and the oral hygiene condition on the other hand. A higher educational level is associated with a better dental health knowledge and, in most cases, the latter is connected with a lower oral hygiene index. School education exerts a greater effect on the level of dental health knowledge than higher or technical education. The state of dental health education and information of the population is not sufficient. Merely 25% of the interviewed graduates and 10% of the individuals having gained a school-leaving certificate reached maximum scores though only some few and easy questions (with a choice of incorrect and correct answers) had been put to evaluate dental health knowledge.
