Tradução e validação de questionário e avaliação da precisão do autorrelato sobre as condições clínicas de próteses totais

Abstract

The assessment of the self-reported health condition represents a quick and inexpensive alternative to measure oral health conditions in a population. However, there is controversy about the reliability of the information obtained from the patient's perception. In addition, for accurate results to be obtained from the application of the instrument, it is necessary that they be translated and adapted transculturally into the language of the target population of the study. This thesis was divided in two chapters: Chapter 1- Aimed to compare the self-report of the user elder on the conditions of their complete denture (CD) with the clinical evaluation considering the aesthetics and function domains. Chapter 2- Aimed to translate and cross-culturally adapt the Patient’s Denture Assessment (PDA) into Brazilian Portuguese (PDA-BR) as well as evaluate the internal consistency and reliability of the PDA-BR. Chapter 1, trained examinators clinically evaluated the CDs of 122 elders using the criteria stability, retention, occlusion and articulation, vertical dimension of occlusion and aesthetics. This evaluation was compared with the users self-report measured using the questionnaire PDA and the same criteria of the clinical evaluation. The results showed that the self-reported information underestimation in 59.1% the clinical evaluation when the aesthetic domain was not included in the analysis. Nonetheless, when this criterion was included in the analysis the underestimation reduced to 8.9%. Chapter 2, the process of translation and validation of the PDA was reported. The reliability and validity of the PDA-BR were tested on a sample of 39 elders, edentulous and users of upper and lower CD. Internal consistency was determined based on Cronbach's α for the construct and all domains separately, and the testretest reliability was determined using the intraclass correlation coefficient. The results of the present study indicate that elderly wearers better identified the CD condition when the aesthetic criterion was evaluated; while self-reported information considering functional criteria (retention, stability, occlusion and vertical dimension of occlusion) underestimated the clinical information. Yet, the PDA-BR seems to be a viable alternative to assess self-report of dentures by Brazilian elder’s complete denture wearers.
