In 1973, the Institute for Postgraduate Dental Education in Jönköping carried out the first dental health examination of people between the ages of three and eighty. Since then, the study, which includes just over 1,400 people, has been repeated every ten years. In 2023, the study will be carried out for the sixth time.

Keeping the mouth healthy is a priority task for the individuals themselves but also for society in general. In order to plan for the provision of resources and for education in the dental care field, it is necessary to have a good knowledge of the general dental health and dental care needs of the population, as well as get an insight into individuals' knowledge and attitudes towards dental health.

During the 70s in particular, the dental health situation was very worrying, but through major preventive efforts it has improved over the years. However, the rate of improvement seems to have slowed and it is therefore important to specifically study the development of dental health over the past ten years.

Unique study

The Jönköping studies are unique due to the age range of the sampling, the repeated cross-sectional perspective, the well-defined geographical area and the standardized methodology. The study includes a complete clinical and radiological examination.

Major dental diseases may have a connection to general health. Quality of life, patient experience and fear of undergoing dental care are questions that need to be answered both with a view to how it is today, but also how these things have changed over time.

Foundation for future dental care

Based on the actual oral health situation in the population, calculations can be made to support the future dimensioning of dental care for an equal and sustainable oral health in the population.

One of the major conclusions of the Jönköping study emphasises the importance of preventive care, or prophylaxis. This is something that is considered to be behind much of the good oral health that we actually have in Sweden today.
