Development of a Mobile Application to Enhance Knowledge, Awareness and Communication of Dry Mouth Amongst Dental Practitioners and Patients: A South Texas Oral Health Network Study

Background Dry mouth, also commonly known as "xerostomia", is a prominent symptom that is often overlooked by dental practitioners and patients. The purpose of this study was to pilot the development of a mobile application for assessing dry mouth symptoms. The application will allow patients to self-assess and enhance knowledge, awareness and communication with dental practitioners in their management of dry mouth. Method The first phase of the study was to draw on common knowledge and awareness by conducting two focus groups of dental professionals and community members on content, practicality, functionality, design, and effectiveness. The second phase of the study was the development of the dry mouth mobile application followed by the third phase of the study that consisted of face-validity interviews to obtain feedback on the application. Results Fifty two percent (n=15) of the dental professionals estimated being aware of the prevalence of dry mouth in 40% or more of their patients. Thirty Nine percent of (n=9) community estimated being aware of the prevalence of dry mouth in 40% or more of the community. When asked about their awareness of the etiologies of dry mouth, 100% (n=29) of dental professionals reported that multiple medications and smoking were primary factors whereas the community members indicated that illness and dehydration (87%, n=20) were primary factors in dry mouth. Dental professional's (25% n=7) were very confident in recognizing symptoms and 28% (n=8) were very confident they knew how to manage dry mouth symptoms. Furthermore, 22% (n=5) of the community members were also very confident about recognizing dry mouth symptoms and 13% (n=3) were very confident knowing how managing it. The ToP report generated from the discussions identified "themes" that were utilized in the development of the mobile application. Most individuals who participated in the validity interviews agreed that the dry mouth mobile application was useful, appealing, easy to use and the self-assessment test gave clear and concise information. The application was made available to download from the iTunes Appstore (2019-2020). Conclusion The dry mouth pilot study indicated that the mobile application was beneficial for self-assessment and easy to use. Development of advanced technology tools such as the dry mouth application can promote communication between patients and their dental practitioners to discuss management options for dry mouth.
