Perception and significance of dental appearance: the case of missing teeth.

The perception and significance of dental appearance was investigated in three groups of patients. One group 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 a 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.
