Plain English Summary

Background and study aims
Dental caries (tooth decay leading to holes in the teeth) and periodontal (gum) diseases are two of the most common diseases of the mouth (oral disease). Studies on how they occur help in preparing programs to prevent them. This study looks at the oral health of people living in the West Pomeranian region in Poland investigating, for example, why they may come to a dental surgery for treatment, how often they go to the dentist, how they brush their teeth, if they have a fear of going to the dentist and what their opinion is of dental services in general.

Who can participate?
Adults (aged at least 18) living in the West Pomeranian region in Poland.

What does the study involve?
All participants are asked to fill in a questionnaire. The questionnaire comes in two parts. The first part contains questions on personal data, such as the participants gender, age, where they live, level of education and how much each person earns in their household. The second part contains questions on how they use dental services, how often they go to the dentist, reasons for going or delaying going to see a dentist, if they fear going to the dentist, and their oral hygiene habits (how often do they clean their teeth, for example, how often do they replace their toothbrush and what dental products do they use). The questionnaire also has questions regarding the participants opinions on the services given. Each participant also has a dental check-up, and have short interview about how they themselves see their general health.

Dental caries, periodontal diseases


This study was conducted in private dental facilities in the city of Szczecin, Poland, on 301 randomly chosen patients undergoing dental treatment.

The patients were asked to fill a self-administered questionnaire and were examined by dental professionals. The questionnaire consisted of two major parts. First part contained questions related to patients’ personal data including gender, age, place of residence, education and income per person in a household. The second part consisted of questions related to the utilization of dental services, dental attendance, reasons of attending and delaying visits, fear of the dentist and hygiene habits (i.e. frequency of brushing teeth and replacing toothbrush, use of dental products). It also consisted of questions regarding patients’ opinion on the range of services covered by the public insurance and opinion on the provided services. Overall there were 24 questions, providing an insight on patients’ socio-economic status and dental habits.

Clinical examination was performed in the dental environment, in artificial light, with use of mirror and dental probe in accordance with World Health Organization (WHO) recommendation. The examination was preceded with a short interview, to determine patients’ evaluation of their health (cardiovascular diseases, metabolic disorder, blood diseases, infectious diseases, smoking habits). Results were added to the results acquired from the dental data sheet of own design.
