title: Linking oral health, general health, and quality of life.
abstract: The aim of this work was to assess the association among oral health, general health, and quality of life (QoL). The Oral Health Impact Profile (OHIP-49) and the RAND-36 were distributed amongst 118 psychology freshmen. Additionally, two single items self-rated general health (SRGH) and self-rated oral health (SROH) - were administered. Kruskal-Wallis and Mann-Whitney U-tests were used to evaluate differences between SRGH and SROH categories, regarding OHIP subscale scores and RAND subscale scores. More than 75% of the subjects rated their oral and general health as good. Mean OHIP scores and RAND scores indicated a relatively good oral- and general health-related QoL respectively. The correlation between oral and general health was weak. Significant differences were found between SRGH categories regarding RAND subscale scores, except for the 'role emotional' and 'mental health' subscales. Significant differences were also found between SROH categories regarding OHIP subscale scores, except for the 'psychological disability' subscale. However, no significant differences were found between SRGH categories regarding OHIP subscale scores, or between SROH categories regarding RAND subscale scores. The findings suggest that oral health, general health, and QoL have different determinants. Furthermore, oral health and general health appear to be mostly unrelated in this seemingly healthy population. It is proposed that if no apparent disease is present, oral and general health must be regarded as separate constructs.
