BACKGROUND: Despite numerous studies on the quality of life of patients with dental issues, no specific questionnaire is available for patients with total loss of teeth.
AIM: This study aimed to establish the level of validation and automation effectiveness of the OHIP-20 DG questionnaire for assessing life quality satisfaction of patients who received fully removable plate prostheses.
MATERIAL AND METHODS: The questionnaire was validated by analyzing the psychometric parameters of 50 patients based on the results of the questionnaire survey (17 women, 33 men; aged 4287 years).
RESULTS: The reliability (self-consistency) of the OHIP-20 DG questionnaire was adequate based on the following values: Cronbachs alpha coefficient, 0.780.81; individual functional scales, 0.660.73; convergent validity, 0.1290.503; divergent validity, 0.00040.504; and discrimination, 0.400.89. The scaling success rate of symptomatic subscales ranged from 91.67% to 100%.
CONCLUSION: The OHIP-20 questionnaire is suitable as a measuring tool for assessing the life quality satisfaction of patients who received fully removable plate prostheses. The OHIP-20-DG application for mobile devices reduces the amount of routine operations in collecting data and processing examination results; thus, it can be recommended for clinical work in dental prosthetics.
