Studying the different indicators of functional dentition classification can contribute to the understanding of the associated factors, and thus help in the definition of strategies associated with oral health care. This approach has been little explored in the literature, especially when considering the older age group. Aim The aim of this study is to evaluate the factors associated with three distinct functional dentition classification. Methods Cross-sectional exploratory study using secondary data from the Frailty in Older Brazilians (FIBRA) Project of 876 older adults living in Campinas, Brazil. The indicators of dental function assessed was number of natural teeth present, occluding pairs of teeth and the Eichner index, which were verified by trained dentists, following the World Health Organization criteria for epidemiological studies in oral health. The explanatory variable assessed was the self-perception of oral health-related quality of life measured by the Geriatric Oral Health Assessment Index (GOHAI) and its dimensions. It was also collected sociodemographic information such as age, gender, race/ethnicity, schooling, family income, smoking behavior and frailty status. The association was verified through Poisson regressions for number of teeth and pairs of teeth in occlusion and multinomial regression for the Eichner index, adjusted by sociodemographic and health variables. Results Lower prevalence of participants with less than 21 teeth who negatively perceived GOHAI´s pain and discomfort dimension and higher prevalence of having less teeth among the ones that negatively perceived GOHAI´s physical and functional dimensions. No association was found between the perception of quality of life and occlusion pairs of teeth and the Eichner Index. Conclusion Two out of three indicators assessed were associated with quality of life. Therefore, it is important to select sensitive indicators to be able to identify and better comprehend this relationship.

Resumo Objetivou-se uma abordagem qualitativa de fatores que determinariam a qualidade de vida de pacientes com carcinoma papilífero de tireoide tratados. Foram feitas 16 entrevistas em profundidade com indivíduos de 18 a 45 anos sobre suas representações e experiências com esta enfermidade, seguidas por análise de conteúdo de enunciados. Os resultados contêm aspectos já previstos em questionários estruturados sobre qualidade de vida, mas outros estão parcialmente presumidos nesses questionários (manejo do conceito de etiologia da doença, a inserção “forçada” dos pacientes no universo conceitual médico, o medo do prognóstico e as mudanças “positivas” no estilo de vida). A interpretação desses resultados beneficiou-se de elaborações teóricas de desenvolvimento recente: as angústias sobre a experiência da doença parecem configurar-se, para os participantes, como um “risco moderno”, no contexto de uma “sociedade de riscos”. O desenvolvimento de questionários estruturados de qualidade de vida requer constantes estudos qualitativos que captem mudanças nos aspectos subjetivos do construto, dada a dinamicidade dos significados histórico-culturais e psicológicos do processo saúde-doença, constantemente influenciados por inovações tecnológicas e sucessivas interpretações epidemiológicas.

Abstract The aim of this study was to develop a qualitative approach of determinant factors of the quality of life of treated patients with papillary thyroid carcinoma. Sixteen in-depth interviews were conducted with individuals 18 to 45 years old regarding their disease representations and experiences, followed by statements content analysis. The results show issues already provided in structured questionnaires about quality of life, although others were only partially assumed in these surveys (management of the concept of disease etiology; the “forced” patient introduction into the medical conceptual universe; the fear of the prognosis and positive changes in lifestyle). The results interpretation were benefited from recently developed theoretical elaborations: the anxieties related to illness experience seem to be configured as a “modern risk”, in the context of a “risk society”. The development of structured questionnaires on quality of life requires frequent qualitative studies to capture changes in subjective aspects of the construct, given the dynamic changes of historical, cultural and psychological meanings of the health disease process, constantly influenced by technological innovations and continuing epidemiological interpretations.
