Abstract
This study explored the influence of individual and social factors regarding intentions and behaviors related to prosthodontic treatment, using the theory of planned behavior (TPB). A cross-sectional study was designed with a sample of 225 individuals with some degree of tooth loss. A questionnaire was used containing factors that would have potential influence on the intentions and behaviors of individuals, as well as clinical and sociodemographic data. Descriptive statistics, internal consistency analysis, chi-square test for trend, and logistic regression were used for data analysis. The TPB components – attitude toward the behavior (ATB), subjective norm (SN), and perceived behavioral control (PBC) – showed good internal consistency (alpha = 0.60–0.78). Intention and behavior were associated with TPB components and the overall scale. Similarly, positive intentions and behaviors were associated with age, upper tooth loss, anterior tooth loss, and higher social status. Multiple logistic regression showed that intention was associated with PBC (OR =1.57;

) SN: an individual’s perception of social normative pressures or relevant others’ beliefs that he or she should or should not perform such behavior; (<bold>3</bold>

) intention: an indication of an individual’s readiness to perform a given behavior based on ATB, SN, and PBC, with each predictor weighted for its importance in relation to the behavior and population of interest; and (<bold>5</bold>
