P>Studies investigating the relationship between personality traits and quality of life related to the types of dental prostheses are scarce. The aim of the present study was to assess personality traits and their impact on quality of life for individuals treated with either conventional mandibular dentures (CMD) or implant-supported overdentures. Fifty patients with CMD and 50 patients with implant-supported mandibular overdentures (IMOD) were recruited. Individuals were examined; clinical and demographic data of interest were collected. All participants agreed to answer two questionnaires: the Oral Health Impact Profile (OHIP-14), which assessed quality of life related to oral health, and the Neuroticism Extraversion Openness Five-Factors Inventory (NEO FFI-R), which evaluated five personality domains. The influence of variables of interest on oral health-related quality of life was tested by univariate analysis and multiple linear regression. Patients with CMD reported higher levels of impact on quality of life (OHIP-14 = 10 center dot 30 +/- 5 center dot 88) when compared to patients with IMOD (OHIP-14 = 6 center dot 52 +/- 5 center dot 91; P = 0 center dot 002). Multivariate predictive regression model for quality of life included neuroticism, conscientiousness and gender for the conventional mandibular denture group (P < 0 center dot 05; R2 = 36 center dot 59%), whereas neuroticism, openness and schooling (P < 0 center dot 05; R2 = 21 center dot 09%) were included in the implant-supported mandibular denture group model. Patients with IMOD had less impact on quality of life than patients with CMD. Personality traits, mainly neuroticism, had a significant influence on oral health-related quality of life linked to a chosen modality of prosthetic therapy.
