Factors Affecting Oral Health-Related Quality of Life Among Elderly Croatian Patients.

Abstract

Oral health-related quality of life (OHRQoL) as a multidimensional concept is affected by many factors. Therefore, the aim of this study was to determine which demographic and subjective factors are significantly affecting the OHRQoL among the elderly people wearing complete removable dental prostheses (CRDP). This questionnaire-based study included 301 participants, residents of elderly care homes (in Zagreb and Slavonski Brod, Croatia) wearing maxillary and/or mandibular CRDP. The questionnaire used in this study consisted of two sections; the first section included questions giving general information and in the second section the Croatian version of Oral Health Impact Profile (OHIP)-49 questionnaire with 49 items representing seven OHIP domains was used. Participants were aged between 60-99 years, with average age of 74 ± 12.1 years. OHIP summary score was 26.5. The highest average OHIP mean values in the domain of functional limitation amounted to 6.7, physical pain 5.1, and physical disability 5.9. The participants' age, education, profession, residence place size, type of CRDP, and the time of denture wearing period all statistically significantly affected OHRQoL (p < 0.05). General and sociodemographic factors had a significant influence on the participant's subjective perception of oral health and OHRQoL. Younger participants, participants from rural places, those with lower levels of education, and shorter period of denture wearing demonstrated a higher impact on OHRQoL.
