Association between personality traits and quality of life in patients treated with conventional mandibular dentures or implant-supported overdentures



Association between personality traits and quality of life in patients treated with conventional mandibular dentures or implant-supported overdentures



Journal of Oral Rehabilitation 38(6): 454-461



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=10·30 ± 5·88) when compared to patients with IMOD (OHIP-14=6·52 ± 5·91; P=0·002). Multivariate predictive regression model for quality of life included neuroticism, conscientiousness and gender for the conventional mandibular denture group (P<0·05; R(2)=36·59%), whereas neuroticism, openness and schooling (P<0·05; R(2)=21·09%) 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.
