Influence of the dental prosthetic status on self-perceptions of health and treatment needs: A cross-sectional study of middle-aged adults with chronic disease.

Background: Subjective aspects of dental prosthesis need in middle-aged adults are poorly explored, especially when the population presents chronic diseases. Objectives: To investigate if the use and necessity of dental prosthesis influence the self-perceptions of health and dental treatment need in middle-aged adults with chronic diseases.

Material And Methods: A cross-sectional study was performed in 210 middle-aged adults. Socio-demographic aspects, dental services use, oral and general perceptions of health, dental treatment need and OIDP were assessed using a standardized questionnaire. One trained dentist evaluated the use and necessity of dental prosthesis. Data were analyzed using Chi-square and multivariate logistic regression (<0.05).

Results: The use of dental prosthesis showed a proportion of 2.2:1 for upper to lower arch. Dental prosthesis need was largely prevalent (90 and 95% in upper and lower arch, respectively). The self-perceptions of dental treatment need and oral health were associated with the use and necessity of dental prosthesis (<0.05), which could not be observed in relation to the general self-perception. The adjusted model demonstrated that the subjective necessity of dental treatment was 16.04 (1.92-133.7) fold higher in individuals with necessity of rehabilitation in the lower arch. Besides, a positive self-perception of oral health (satisfied) was 2.59 (1.38-4.85) more expressive in individuals that used a dental prosthesis in upper arch.

Conclusions: The self-perception of oral health was influenced by the use of maxillary dental prosthesis in individuals with chronic disease. Moreover, individuals were more likely able to perceive treatment need when the lower jaw was affected by tooth loss. Tooth loss, epidemiology, personal satisfaction, aged, chronic disease.
