[Self-perception of oral health and impact on quality of life among the elderly: a quantitative-qualitative approach].

A qualitative-quantitative approach was used in this study to obtain a clearer understanding of the relationship between self-perception, impact on quality of life and oral health among the elderly. Clinical examination and recorded interviews with objective and discursive questions were conducted with 45 institutionalized elderly people. Descriptive analyses of quantitative data were made. The interviews were transcribed and a systematic reading of the interviews was carried out selecting the components related to the categories under analysis. Photographic images of the oral clinical status were correlated with participants' speech. Quantitative analysis revealed: an average of 4.8 teeth; DMFT were 29.9; 57.7 % were toothless; 60% believed they did not need dental care; 75% suffered a great impact on quality of life due to oral health conditions, despite the fact that 67% evaluated their oral health positively. Underestimation of symptoms, lack of hope and resignation due to limitations regarding poor clinical status were detected. Most elderly people viewed such limitations as a consequence of aging and not as a problem that may be solved. This reality can be changed through information and guidance for elderly people.
