Abstract
Objective: This study conducted correlation analysis between subjective surveys measuring xerostomia (mouth dryness) and objective assessment methods for measured values of oral moisture. By doing so, it sought to identify the appropriateness of assessment tools to measure xerostomia.
Methods:The study carried out a questionnaire survey among 37 healthy male and female adults without general diseases after getting their consent following the review of Dankook University IRB Committee. Measurement of oral moisture was done using Mucus (Life Co.). The questionnaire used questions of precedent research related with subjective xerostomia diagnosis. For analysis, the study, conducted reliability test by each question, internal consistency and correlation analysis between measured values of oral moisture.
Results: As a result of comparing between the questions—subjective assessment tool—and measurement of oral moisture—objective one—, reliability between the questions turned out relatively high at 0.840, while internal consistency turned out between 0.40 and 0.75. As a result of correlation analysis between assessment tools, there was correlation between the questions (p<0.05, p<0.01), whereas there was no correlation between the questions and measured figures of oral moisture (p>0.05).
Conclusion: As per the findings of this study, there was no correlation between subjective surveys and measured values of oral moisture. And yet the study believes there is need for diverse research on effectiveness of subjective survey methods and measuring tools in connection with xerostomia.
