Objectives
Identify and analyze determinants for oral-health-related quality of life among adults admitted to a Danish research program on general health and lifestyle (DANHES 2007-2008)

Materials and methods
Study population: 4402 volunteers invited among participants of main study (n=18065) in 12 Danish cities.
Age 18-96 years (average 54)
Structured interviews (from main study and dental study) and clinical oral examination
Oral-health-related quality of life measured by a 10 item index
Non-parametric statistical methods, chi-square, simple and multivariate logistic regression
Conclusions
Regular dental visits and high number of natural teeth are determinants
for high level of oral-health-related quality of life
Untreated caries, wearing dentures and high caries experience
are determinants for reduced oral-health-related quality of life


Results
33 persons were edentulous, 7 % wore dentures , mean DMFS = 62
88% were regular users of dental care
24 % reported oral-health-related quality of life problems
6 % reported score of 3 or more oral-health-related quality of life problems (maximum score = 30)

Most frequent problems because of appearance of teeth (or dentures) :
Feeling embarrassed (13 %)
Feeling tense (9 %)
Avoid smiling/laughing (6 %)
Difficulties with eating food due to mouth or teeth problems 9 %
