Oral health‐related quality of life in X‐linked hypophosphataemia and osteogenesis imperfecta

다국어 초록 (Multilingual Abstract)

X‐linked hypophosphataemia (XLH) and osteogenesis imperfecta (OI) are rare congenital disorders characterised by skeletal dysplasia. The two disorders may include dental anomalies potentially affecting individual well‐being. The aims of study were (a) to assess the oral health‐related quality of life (OHRQoL) in Danish adults with XLH or OI, and (b) to compare the results of the groups. A cross‐sectional study including 35 adults with XLH, 56 adults with OI type I and 17 adults with OI types III‐IV was conducted. The OHRQoL was assessed by the 49‐item version of the questionnaire Oral Health Impact Profile (OHIP). Summed domain scores (seven) were compared between XLH and OI groups. Prevalence of severe impact on OHRQoL (scores 3‐4) was compared between groups. The median scores in XLH group exceeded the medians in OI (P < .05) in the domains functional limitation (XLH:6.5; OI:4.0), pain (XLH:9.5; OI:5.0), psychological discomfort (XLH:5.5; OI:2.0), psychological disability (XLH:2.0; OI:0.0), handicap (XLH:2.0; OI:0.0) and total OHIP (XLH:35.0; OI:14.0). Differences in domains physical disability (XLH: 4.0; OI: 1.0) and social disability (XLH: 0.0; OI: 0.0) were not significant. Prevalence of severe impact on OHRQoL in the XLH group significantly exceeded the level in OI group in the domains functional limitation (XLH: 59%; OI: 35%), psychological discomfort (XLH: 38%; OI: 20%) and physical disability (XLH: 32%; OI: 13%). In conclusion, adults with XLH experience a higher negative impact on their OHRQoL than adults with OI. Only to a minor degree, individuals with OI types III‐IV experience a higher impact on OHRQoL than individuals with OI type I.
