Correlation between oral health-related quality of life and objectively measured oral health in people with ehlers–danlos syndromes

Abstract

It is a well-known fact that people with Ehlers–Danlos syndromes (EDS) report a worse oral health-related quality of life (OHRQoL) than the general population. The aim of this study was to examine whether there is a correlation between the subjective OHRQoL and the objectively measured oral health in people with EDS. To determine the subjective OHRQoL, the German version of the 14-item Oral Health Impact Profile (OHIP-14) questionnaire was used. Furthermore, all participants in the study were clinically examined, and the measured parameters were recorded using the Physical Oral Health Index (PhOX). Altogether, records of 46 participants were collected. The median (interquartile range (IQR)) of the OHIP-14 was 17 (23) points and the median of the PhOX was 73 (16) points. However, a statistically significant correlation could not be demonstrated (r = -0.240, p = 0.108). In the observed cohort, for participants who reported having pain often or very often, the OHIP score (median = 24, IQR = 18, p < 0.01) was higher than the score of the group given by participants who never or intermittently experienced pain (median = 8, IQR = 18). In conclusion, patients with EDS showed a reduced OHRQoL, although it was not possible to observe an association between the subjective OHRQoL and the objective oral health. However, participants who often or very often suffer from pain in their tooth, mouth, and jaw areas showed a reduced OHRQoL.
