          Abstract

          Background

          Aspects of oral health related quality of life (OHRQoL) attracted an increased attention recently.

          Objective

          The 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.

          Methods

          Hungarian 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.

          Results

          The 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.

          Conclusions

          Here 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.

          Development and evaluation of the Oral Health Impact Profile.

          The capacity of dental clinicians and researchers to assess oral health and to advocate for dental care has been hampered by limitations in measurements of the levels of dysfunction, discomfort and disability associated with oral disorders. The purpose of this research was to develop and test the Oral Health Impact Profile (OHIP), a scaled index of the social impact of oral disorders which draws on a theoretical hierarchy of oral health outcomes. Forty nine unique statements describing the consequences of oral disorders were initially derived from 535 statements obtained in interviews with 64 dental patients. The relative importance of statements within each of seven conceptual subscales was assessed by 328 persons using Thurstone's method of paired comparisons. The consistency of their judgements was confirmed (Kendall's mu, P < 0.05). The reliability of the instrument was evaluated in a cohort of 122 persons aged 60 years and over. Internal reliability of six subscales was high (Cronbach's alpha, 0.70-0.83) and test-retest reliability (intraclass correlation coefficient, 0.42-0.77) demonstrated stability. Validity was examined using longitudinal data from the 60 years and over cohort where the OHIP's capacity to detect previously observed associations with perceived need for a dental visit (ANOVA, p < 0.05 in five subscales) provided evidence of its construct validity. The Oral Health Impact Profile offers a reliable and valid instrument for detailed measurement of the social impact of oral disorders and has potential benefits for clinical decision-making and research.
