Abstract
BackgroundAspects of oral health related quality of life (OHRQoL) attracted an increased attention recently.ObjectiveThe aim of the study was to assess self-reported oral health related quality of life (OHRQoL) among patients requiring prosthetic rehabilitation and to determine the rate of improvement 1 month and 6–12 months after therapy. In addition, effect of age, gender, oral health indicators and denture types before treatment were assessed on OHRQoL as evaluated and reported by the patients.MethodsHungarian version of OHIP-49 (OHIP-49-H) questionnaire was completed before oral rehabilitation (T0-phase) by 389 patients undergoing prosthetic replacement. After 1 month (T1-phase) and 6–12 months (T2-phase) recall periods 235 and 92 patients completed the questionnaire. The median interquartile range (IQR) values of the total OHIP-49-H score were calculated for T0-, T1- and T2-phases. Reliability of the questionnaire was checked by Cronbach’s statistics. Age, gender, oral health indicators and denture types of patients before and after treatment were recorded and treatment-associated changes in OHRQoL were evaluated.ResultsThe study demonstrated the excellent reliability and internal consistency of OHIP-49-H by a high and narrow range of Cronbach’s alpha value (0.81-0.93). A median OHIP-49-H score of 52; IQR = 25-83 demonstrated a poor OHRQoL on first admission. Decreasing median total OHIP-49-H scores 1 month (24; IQR = 9-51; p < 0.001) and 6–12 months (20; IQR = 7-37; p = 0,055) after therapy indicated an improvement of OHRQoL. Patients’ age and CPI value assessed before treatment proved to be significant factors of OHRQoL.ConclusionsHere we presented representative data about self-assessed OHRQoL of patients requiring prosthetic treatment from Hungary using OHIP-49-H questionnaire. The results demonstrated that the restoration of oral health was associated with an improvement in patients’ OHRQoL. According to the demographical and T0 phase clinical status, the treatment was more effective in the respect of OHIP-49-H score improvement among females (than among males), among younger (than among more aged), and among patients with more serious CPI assessed at T0. The type of prosthetic interventions did not exert a significant effect on total OHIP-49-H score, suggesting that the improvement in OHRQoL is independent from the type of denture applied.

Summary
Aspects of oral health related quality of life (OHRQoL) attracted an increased attention recently. It has been accepted that the objective component of oral health (physical indicators) and the subjective component (patients’ perception of oral conditions) are complementary and cannot be separated in clinical practice [2]. One of the most accepted measurement instrument is the internationally used Oral Health Impact Profile (OHIP) questionnaire [3]. The Hungarian adaptation of the 49-item Oral Health Impact Profile (OHIP-49-H) questionnaire has recently been developed and validated [2]. Several studies were aimed at the development and validation of the OHIP49 questionnaire, only few of them evaluated the influence of clinical factors on OHRQoL using OHIP-49 as a tool [4, 7,8,9]
