• Resumen

  • The Theory of Planned Behavior (TPB) was used to assess subjects' intentions and behavior to predict willingness to undergo prosthodontic care. A questionnaire was administered to 225 adults with history of teeth loss who currently were not under prosthodontic treatment. The questionnaire comprised TPB components (attitude toward behaviour [ATB], subjective norm [SN], and perceived behavioral control [PBC]) containing items with potential influence on the intentions and behavior of individuals toward prosthodontic care. Clinical and socioeconomic data were also assessed. A path regression model was constructed explaining two dependent variables simultaneously: one explained the influence of PBC on intention (R2 = 0.04) and another explained the influence of dental arch, position of lost teeth, socioeconomic status, and PBC on behavior (R2 = 0.31). It was concluded that PBC was a relevant TPB component that encompasses perception of costs, opportunity cost, perceived need, and access to dental care. Clinical and socioeconomic factors were also major determinants of behavior toward prosthodontic treatment.
