Reliability and Validity of a Nepalese Version of the Oral Health Impact Profile for Edentulous Subjects

Reliability and validity of a Hindi version of the Oral Health Impact Profile (OHIP-EDENT-H) for edentulous subjects: A Cross-Sectional study

Aim

The study aimed to translate the OHIP-EDENT into Hindi and assess its validity and reliability.

Methods

The study included 150 participants whose demographic information was collected using the Modified Kuppuswamy Socio-economic Scale. The Oral Health Impact Profile in Edentulous (OHIP-EDENT) was translated into Hindi using the standard forward-backward method. Test-retest reliability was assessed using the Intra-class Correlation Coefficient (ICC) and internal consistency using Cronbach's alpha. The Kaiser-Meyer-Olkin (KMO) test and Bartlett's test of sphericity coefficient were used to conduct Exploratory Factor Analysis (EFA) and confirm the Construct validity. To establish Convergent validity, the relationship between the global question and the OHIP-EDENT-H subscale scores was observed.

Results

The data was analyzed with a confidence level of 95 %, and statistical significance was interpreted as a p-value of less than 0.05. The Cronbach's alpha score for OHIP-EDENT-H was 1.00, indicating high internal consistency. The corrected item-total correlations ranged from 0.665 to 0.923, and the total ICC score was 0.763, demonstrating good reliability. The subscales' intra-class correlation coefficient values ranged from 0.968 to 0.997, indicating high reliability. However, items 4, 6, 13, 17, 18, and 19 had factor loadings below the acceptable threshold of 0.40 in the factor analysis. Additionally, the total and subscale scores of the OHIP-EDENT-H showed significant correlations with global question, with correlation coefficients ranging from 0.665 to 0.923.

Conclusion

The Hindi version of OHIP-EDENT is a reliable and valid tool for evaluating the OHRQoL of Hindi-speaking edentulous individuals.

Impact of Acrylic and Silicone-Based Soft-Liner Materials on Biting Force and Quality of Life of the Complete Denture Wearers: A Randomized Clinical Trial

This rerandomized clinical trial evaluated the influence of soft liners (SL) on biting force, pain perception, and the oral health-related quality of life (OHRQoL) of complete denture wearers. Twenty-eight completely edentulous patients complaining of ill-fitting lower complete dentures were selected to participate in the study from the Dental Hospital, College of Dentistry, Taibah University. All patients received new complete maxillary and mandibular dentures; then they were randomly divided into two groups (14 patients in each group): the acrylic-based SL group, in which the mandibular denture was lined with an acrylic-based soft liner, and the silicone-based SL group, in which the mandibular denture was lined with a silicone-based soft liner. OHRQoL and maximum bite force (MBF) were assessed in this study before denture relining (baseline), then at one month and three months after relining. The finding showed that both treatment modalities significantly improved the OHRQoL of included patients at one-month and three-month periods compared to baseline records (i.e., dentures before relining) with a statistically significant difference (p < 0.05). However, there is no statistical difference between groups at the baseline, one-, and three-month follow-up periods. Regarding maximum biting force, when acrylic-based SL is compared to silicone-based SL, there is no statistical difference between groups at baseline (75 ± 31 and 83 ± 32 N) and one-month follow-up periods (145 ± 53 and 156 ± 49 N); however, after three months of function, the silicone-based group recorded 166 ± 57 N statistically significant high biting force compared to the acrylic-based group that recorded 116 ± 47 N (p < 0.05). Permanent soft denture liners positively affect maximum biting force, pain perception, and OHRQoL more than conventional dentures. After three months, silicone-based SL outperformed acrylic-based soft liners in maximum biting force, which may indicate better long-term results.

Cross-cultural adaptations of the oral health impact profile - An assessment of global availability of 4-dimensional oral health impact characterization

OBJECTIVE

The 4-dimensional (4D) structure of oral health-related quality of life (OHRQoL), comprising of the dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact, is clinically plausible and psychometrically solid. The original Oral Health Impact Profile (OHIP) instrument and its short-form versions have been proven to lend themselves well to the assessment of these 4 OHRQoL dimensions. However, whether this 4-dimensional approach to oral health impact characterization can be performed on a global scale, that is, for most of the world's population, is not known. The purpose of this study was perform a systematic review to identify all cross-cultural adaptations of OHIP versions with 49, 20/19, 14, and 5 items. The global availability of 4D oral health impact characterization was investigated.

METHODS

We performed searches of electronic databases- Scopus, Pubmed, Web of Science, along with hand searching in June 2022 to identify all cross-cultural language adaptations of the different OHIP versions available in the literature. Whether the 4D oral health impact assessment can be considered a global approach was judged based on the criteria whether 4D psychometric information was available for at least 75% of the most widely spoken languages with an OHIP version.

RESULTS

We identified 82 studies with a total of 90 individual OHIP language versions for 45 languages. Among the top 20 languages with most first-language (native) speakers, 16 (80%) had OHIP versions. Among the top 20 languages with the most first- and second-language speakers, also 16 (80%) had OHIP versions. Of these 16 OHIP versions, across both language categories, 13 versions (81%) allowed for 4D oral health impact characterization.

CONCLUSION

Four-dimensional oral health impact assessment using the dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact can be considered a globally available approach given that OHIP versions with 4D information are readily available for most widely spoken languages. Thus, psychometrically sound, practical, and internationally comparable oral health impact characterization can be easily performed to study population oral health and determine oral disease impact and treatment efficacy for dental patients.

Reliability and validity of the Turkish version of oral health impact profile for edentulous subjects

Purpose

The validated translations of the OHIP-EDENT exist in different languages; however, there is no reliable and validated Turkish translation. The present study was conducted to evaluate the reliability and to validate the Oral Health Impact Profile in edentulous subjects translated to Turkish (OHIP-EDENT-T).

Materials and methods

The study sample included 104 conventional complete denture wearers (58 women and 46 men, mean age: 61.13 ± 9.43 years). The original English version of OHIPEDENT was translated into Turkish using a forward-backward method and applied to the subjects. The reliability of the OHIP-EDENT-T was evaluated using internal consistency and the test-retest method. Validity was determined as construct and convergent validity. The construct validity of OHIP-EDENT-T was assessed using exploratory and confirmatory factor analysis.

Results

The Cronbach's alpha value for OHIP-EDENT-T was 0.890. The intraclass correlation coefficient (ICC) was 0.749 for the OHIP-EDENT-T total score, and ICCs for the subscales ranged from 0.630 (95% CI = 0.501-0.823) to 0.859 (95% CI = 0.531-0.897), indicating good to excellent agreement. The Kaiser-Meyer-Olkin value for sampling adequacy was 0.820 and results of Bartlett's sphericity test indicated statistical significance (χ2=1139.767; df=171, p=0.001). This showed that factorial analysis could be applied to the data set. The three-factor structure of the scale explained 81.1% of the observed variance. The agreement of the three-factor solution was further tested with confirmatory factor analysis, and the fit index was found to be acceptable (chi-square fit test=1.449, RMSEA=0.040, GFI=0.94, CFI=0.93).

Conclusion

Within the limitations of this study, it can be concluded that OHIP-EDENT-T is a valid and reliable instrument for evaluating the quality of life of edentulous patients.

Bosnian Version of Oral Health of Edentulous Patients (OHIP-EDENT-B&H) Questionnaire: Assessment of Reliability and Validity

Background/Aim: The aim of this study was to assess of the internal coherence of Bosnian translated version of the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT-B&H), and evaluated the validity of this version.

Material and Methods: OHIP-EDENT-B&H questionnaires were completed by 117 edentulous patients and specialists of prosthodontics in health institutions of central Bosnia.

Results: Test-retesting analysis showed strong correlations, r ranging from 0.46 to 0.58, respecting complete dentures, with Kappa= 0.68, that indicated reliability of the questionnaire. The lowest reliability was obtained for Psychological disability (n= 117, α= 0.636) and the highest was obtained for Social disability (α= 0.859). The reliability of the summary scores for OHIP-EDENT-B&H was good (α= 0.907). Content validity for the test group-retest group did not expose significant differences between the groups tested.

Conclusions: The OHIPEDENT-B&H instrument for verifying of oral-health–related quality of life in edentulous patients demonstrated good reliability and validity in Bosnian patients.

Psychometric Characteristics of the Croatian and the Serbian Versions of the Oral Health Impact Profile for Edentulous Subjects, with a Pilot Study on the Dimensionality

Introduction

The aim was to adapt the Croatian and the Serbian versions of the Oral Health Impact Profile for the edentulous population (OHIP-EDENT-CRO and OHIP-EDENT-SRB).

Methods

The translation and cross-cultural adaptation were carried out in accordance with accepted international standards. A total of 95 and 177 removable denture wearers were recruited in Croatia and Serbia respectively. The reliability was evaluated by calculating Cronbach’s alpha coefficient and by test-retest (30 participants in each country). The concurrent validity was determined by calculating the Spearman’s rank coefficient between the OHIP-EDENT summary scores and one question related to removable denture satisfaction. Construct validity was determined by exploratory factor analysis (EFA). Responsiveness was determined by comparison of the OHIP-EDENT summary scores before and after dental implant placement to support mandibular overdentures (23 patients in Croatia, 21 in Serbia).

Results

Cronbach’s alpha coefficient was 0.92 in Croatia and 0.87 in Serbia. The intraclass correlation coefficient was 0.98 in Croatia and 0.94 in Serbia. In Croatia the Spearman’s correlation coefficient was -0.71 (p<0.001) and in Serbia -0.74 (p<0.001). Both confirmed concurrent validity. Construct validity was tested by EFA, which extracted four factors in each country, accounting for 66.59% of the variance in Croatia and 59.33% in Serbia. Responsiveness was confirmed in both countries by a significant OHIP-EDENT summary score reduction and a high standardised effect size (3.9 in Croatia, 1.53 in Serbia).

Conclusion

The results prove that both instruments, the OHIP-EDENT-CRO and the OHIP-EDENT-SRB, have very good psychometric properties for assessing OHRQoL in the edentulous population.

Comparison of psychometric properties of GOHAI, OHIP-14, and OHIP-EDENT as measures of oral health in complete edentulous patients aged 60 years and more

OBJECTIVES

To compare the psychometric properties of three OHRQoL indicators (GOHAI, OHIP-14, and OHIP-EDENT) in a group of complete edentulous subjects and to explore the ability of these instruments to distinguish between individuals with different prosthetic and oral health status.

METHODS

This was a cross-sectional study. Edentulous individuals aged 60 years and more were recruited between January 2019 and February 2020 in a medical and dental care centers. The Lebanese versions of GOHAI, OHIP-14, and OHIP-EDENT were used. External and internal consistencies were assessed using intraclass correlation coefficient (ICC) and Cronbach alpha, respectively. The concurrent validity was evaluated by testing the indicators against a proxy measure of a similar concept. To test their discriminative abilities, the ADD (GOHAI and OHIP) and SC (GOHAI and OHIP) scores were dichotomized according to the 25th and 75th percentile, respectively, and multivariate analyses were performed using sociodemographic, clinical, and subjective health parameters as explanatory variables.

RESULTS

Two hundred and two edentulous subjects (age: 72.94 ± 7.378 years) were included. The proportion of subjects with no impact was lower for OHIP-EDENT (7.9%) compared to GOHAI (28.2%) and OHIP-14 (38.6%). Reproducibility was satisfactory for all OHRQoL tools since they were able to reproduce the results consistently in time (ICC > 0.80). The Cronbach alpha values were greater than 0.8 indicating acceptable internal consistency. The concurrent validity of the three tools was acceptable since subjects with lower OHRQoL score were less satisfied with their dentures and reported a higher need for self-rated therapy. Concerning the discriminant validity, OHIP-EDENT was more discriminant than OHIP-14 and GOHAI, since it was more able to identify patients with poor prosthetic issues or using instable denture.

CONCLUSION

The OHIP-EDENT was more effective in identifying edentulous individuals with oral and prosthetic problems. Our results can help decide which dental instrument to use to assess the perception of oral health in edentulous individuals. More prospective studies are required to compare their evaluative properties.

A questionnaire study on the impact on oral health-related quality of life by conventional rehabilitation of edentulous patient

Purpose

This study aimed to determine whether complete dentures improve the oral health-related quality of life (OHRQoL) of edentulous patients, and to assess any associations related to age, gender, and OHRQoL.

Material and methods

Hundred edentulous patients who required conventional complete denture treatment were selected for this study. The following inclusion criteria were established: edentulous in both jaws with no previous history of denture treatment and no significant medical history. The patients were selected who satisfied the criteria associated with the class I prosthodoctic diagnostic index. OHRQoL of the patients were assessed twice, once pre treatment (at the first visit) and once post treatment (8 weeks post insertion of dentures) using an instrument called OHIP-EDENT-N. Significant differences in the OHIP-EDENT-N scores between pre treatment and post treatment were calculated using the Wilcoxon Signed-Rank test. Gender differences were assessed using the Mann–Whitney test.

Results

After provision of new complete dentures, all domains of the OHIP-EDENT-N showed significant improvements except physical pain and social disability.

Conclusions

The results of this study indicated that conventional complete denture improved the OHRQoL of edentulous patients.
