Abstract
The perception and significance of dental appearance was investigated in three groups of patients. One had a missing front tooth replaced by partial dentures, which were taken out during the tests. A second group had some missing (pre-)molars. A third group had a complete natural dentition and they acted as control group. Color photographs of the teeth were made and a clinical examination was carried out. The psychological impact of dental appearance was measured by way of scale of words with affective connotations. Social impact was assessed by way of changes in daily activities. Dentists and lay-persons were asked to give an opinion of the dental appearance on the basis of the pictures. It was found that a missing front tooth resulted in less positive feelings and more negative feelings and also that this condition affected daily life activities strongly. Missing (pre-)molars caused less of an aesthetic problem. Dentists and lay-persons were quite alike in their appreciation of dental appearance, whereas the respondents themselves had different opinions. An explanation for these differences and their implications for dentists are discussed.
