The quality of life can be defined, as the perception of the individuals about their position in life, embedded in a cultural context and a value system in relation to their goals, expectations, standards and concerns (1). During the past few decades, there has been an increasing interest in evaluating and measuring the quality of life in the literature (2). It has been reported to be important for both, the individual and the society since it is assessing relevant patient outcomes, help assessing the outcome of clinical trials, comparing the efficacy of different treatments, evaluating the cost-utility and cost-effectiveness of health-care programs and assisting quality assurance(3). A number of instruments for measuring Oral Health Related Quality of Life (OHRQoL) in relation to oral conditions have been designed (4, 5). They include assessment of impairment and the emotional, social and behavioural domains (6).
The Oral Health Impact Profile (OHIP) (7) is one of the most widely used instrument to measure OHRQoL in dentistry (6). It has been translated into many languages including Swedish (OHIP-S) (8), the score has been evaluated and found to have good reliability and validity and it is recommended to be used in further studies (8).

Activity of Daily Living (ADL) is a different construct that assesses the impact of a certain conditions on daily activities. Von Korff included questions measuring disability in a self-report questionnaire, which was used to compare differences between different pain conditions(9). Impact on the ADL was part of the disability score. Research Diagnostic Criteria for Tempomandibular disorder(10) incorporated von Korff instrument(9) concerning disability to measure ADL.

...onent of this study. Only a few population studies described OHRQoL (14). On the other hand, several OHRQoL study have evaluated elderly people (6, 8, 14) or on group sample with special illness(21, 32, 33). Investigating wide-range aged adults normally living in their community gives more understanding of how different oral conditions might affect this community.
Therefore the aim of the present study was to determine self-reported prevalence of different conditions (TMD, BMS, dry mouth and bad breath) together with comparing their influences on OHRQoL, how much impact each condition exerts on activity of daily Living (ADL), and perceived need for treatment. Our hypothesis is that TMD exerts more impact on OHRQoL and negatively affect ADL other than the three conditions. Conditions accompanied with pain and discomfort; TMD and BMS will report more treatment need
