Brief summary: The purpose of this study to investigate attitude, oral health literacy and psychological factors in order to evaluate if these factors are important for oral health in adults.

The hypotheses are:

* Multiple interactive demographic, and social and psychological factors contribute to the level of attitude and oral health literacy.
* There is an association between the level of oral health literacy and oral health status
* A structured intervention based on oral health literacy can change the attitude and improve the oral health status.
* Background knowledge has influence on attitude and oral health literacy
* Individuals with positive attitude towards dental health and dentist are attentive towards their oral health.

Detailed description: This study will be conducted in two stages. The first stage includes a baseline cross-sectional investigation. Oral health literacy level will be assessed by conducting a structured interview. Background variables, attitude, socioeconomic factors and psychological factors shall be assessed using self-administered questionnaires. A clinical examination will be conducted including general health information and extended oral health examination. The oral health examination performed includes record of oral hygiene status such as dental caries and periodontal status. An assessment of oral bacteria will also be performed.

The second stage will be carried out approximately 6 months after starting with the baseline investigation. At that time a modified version of the questionnaires will be used followed by a shorter clinical examination. The modified questionnaires at the second data collection exclude some background variables. The clinical examination carried out during this time will be on dental plaque and bleeding index and the level of oral bacteria.

Eligibility criteria: Inclusion Criteria:
