Relationship between tooth loss, nutritional status and consumption of macro and micronutrients in elderly people from southern Brazil

Maintaining a functional natural dentition plays an important role in keeping a satisfactory nutritional status. The aim of this study was to evaluate the relationship between oral health conditions determined by the presence of edentulism and the number of missing teeth, nutritional status and consumption of nutrients by the elderly. This cross-sectional study comprised 494 independent elderly of both genders, over 60 years of age, registered at the Brazilian public health service in Londrina, southern Brazil. The data collection included: oral examinations; anthropometric measurements by calculating the Body Mass Index (BMI); analysis of food consumption based on a multiple pass 24-hour dietary recall and a food intake frequency questionnaire; and structured interviews to obtain sociodemographic information. Multiple linear regression, the Fisher's Exact test, chi-square and Mann-Whitney tests, were applied at a 5% significance level. The prevalence of edentulism was 47.3%; this predominated in females, age group from 65 to 74 years, low education level and low/medium economic classification. A larger numberof underweight and fewer number of overweight elderly were recorded among the edentulous versus dentate participants (< 0.0001). Significantly lower consumption of several nutrients, as well as fruit, was recorded among the edentulous group. In particular, carbohydrates, vitamins (B1, B9 and C), and the majority of the minerals studied were associated with a larger number of missing teeth. In conclusion, tooth loss was associated with the food consumption pattern of some macro-and micronutrients and the nutritional status of the Brazilian elderly.

Perda dentária e expectativa da reposição protética: estudo qualitativo / Dental loss and prosthetic replacement expectation: qualitative study

Esse estudo qualitativo analisou as repercussões da perda dentária total de usuários do serviço público. Aplicou-se o Oral Health Impact Profile simplificado(OHIP14) a cinquenta voluntários e, após a apuração dos resultados, foram selecionados treze pacientes para entrevistas individuais baseadas em um roteiro com questões abertas. A seleção das pessoas foi de acordo com o grau de percepção do impacto da condição bucal na qualidade de vida, medida pela pontuação OHIP, de forma a incluir a maior variedade de perfis da amostra inicial. Da análise do conteúdo dos depoimentos, verificou-se que a perda dentária total tem forte impacto na vida das pessoas e implica consequências negativas como vergonha, dificuldade em se alimentar, prejuízo ao relacionamento social e sentimento de incompletude. A possibilidade de reposição protética dos dentes gera ansiedade nas pessoas e, embora elas saibam que a utilização das próteses possa representar sacrifícios, a expectativa de retorno ao padrão social geralmente aceito e de recuperação de sua própria imagem rejuvenescida faz valer a pena quaisquer sacrifícios.

This qualitative research analyses the repercussions of total dental loss on people's quality of life. The Oral Health Impact Profile short-form (OHIP14) was applied to 50 volunteers, and after analyzing the results, 13 out of those 50, were selected to be individually interviewed in an opened questions script. The criteria to select these 13 people were: perception of the impact of mouth condition on quality of life measured by the score reached on OHIP. We tried to comprise the sample with a good variety, according to the profile of the initial sample. After analyzing people's statements, it was possible to verify that dental loss had strong negative consequences on people's life, like shame, difficulty to eat, impact on social relationship and feeling of not being complete. The possibility of having their teeth replaced generates some anxiety. Although being aware that wearing total prosthesis represents some sacrifices, people considered it worthwhile because the possibility of regaining the social pattern and the self-image is renewed.

Patients' self-perceived impacts and prosthodontic needs at the time and after tooth loss

Studies on self-perception have demonstrated that tooth loss is associated with esthetic, functional, psychological and social impacts for individuals. However, not all subjects seek treatment immediately after tooth loss, even when desire for replacement is strongly expressed. The aim of this study was to evaluate the perception of patients submitted to tooth extraction about factors associated with tooth loss and prosthodontic treatment, at the time and after extraction. A convenience sample of 211 consecutive patients were clinically evaluated and answered to a questionnaire about perceived impacts and prosthodontic treatment needs. Data were collected at the time of extraction and after a 3-month time interval. Perceived impacts were high (21 to 76 percent at the time and 35 to 87 percent after extraction). From 72.5 percent patients who expressed intention of immediate replacement of edentulous spaces, only 8.1 percent had actually been treated. Financial limitation was considered the most important factor that restricted access to treatment. Bivariate statistical analysis showed association between immediate dental replacement and anterior tooth loss (p=0.00) and extension of edentulous space (p=0.01). Position of lost teeth was associated to perceived functional limitation (p=0.03). Worsened appearance was associated to tooth loss in the maxillary arch (p=0.02), and desire of prosthodontic treatment was associated to the extension of edentulous space (p=0.05). Perceived impacts were more frequent in women than men. It was concluded that although patients usually expressed prosthodontic treatment needs, clinical and financial issues are determinant factors for tooth replacement.

Estudos de autopercepção têm demonstrado que a ausência de dentes pode resultar em impactos estéticos, funcionais, psicológicos e sociais, embora nem todos os indivíduos demandam por tratamento protético imediato após a perda dentária. O objetivo do estudo foi avaliar a percepção de pacientes submetidos a exodontia em relação a fatores associados à perda e ao tratamento protético, no momento e após a perda dos dentes. Uma amostra de conveniência de 211 pacientes consecutivos foi avaliada quanto à condição clínica, autopercepção dos impactos orais e necessidade de tratamento, por meio de exame clínico e questionário, no momento e após 3 meses da exodontia. A percepção de impactos da perda dentária foi alta (21-76 por cento no momento e 35-87 por cento após a exodontia). Dos 72,5 por cento pacientes que relataram pretender a reposição protética imediata apenas 8,1 por cento realizaram o tratamento. A motivação financeira foi relatada como o maior impedimento para o tratamento. A análise univariada mostrou associação entre reposição imediata e localização anterior da perda (p=0,00) e extensão do espaço desdentado (p=0,01), entre localização da perda e limitação funcional percebida (p=0,03). O incômodo com a aparência foi relacionado à localização da perda no arco superior (p=0,02), o desejo por tratamento protético foi relacionado à extensão do espaço desdentado (p=0,05). Na maioria dos aspectos avaliados a percepção de problemas associados à perda foi maior no sexo feminino. Conclui-se que, embora a necessidade percebida de tratamento protético seja alta, fatores clínicos e sócio-econômicos são determinantes para a realização do tratamento.
