Introduction: In several nations, caries in pre-school children remain a significant oral
health issue. In an outbreak period such as the Coronavirus disease 2019 (COVID-19),
remote contact and education aimed at the prevention of oral diseases and the
preservation of children’s oral health are more relevant than ever. Currently, the number
of published applications are far higher than the published scientific studies while the
problems of usability remains vulnerable. Objective: To comprehensively document the
phase of development and usability testing of a mobile application for diet and oral
health, namely Gigiku Sihat, which was primarily intended to be used by parents and
guardians of pre-school children. Materials and methods: The mobile application was
developed using the System Development Life Cycle principle. Apart from searching for
the available oral health application on Android platform, the initial requirement
gathering process consisted of situational analysis, concept generation, content
development, and features and functional requirement determination. The mobile
application design and implementation evolved at each phase before being finalised.
Results: Gigiku Sihat was successfully developed in the Bahasa Malaysia. Finalised Gigiku
Sihat was installed on mobile devices to determine the usability using translated and
validated System Usability Scale questionnaire namely Skala Kebolehgunaan Aplikasi
Mudah Alih (SKAMA). The mean score usability with score of 68 and above was deemed
to have good usability. This study found that Gigiku Sihat mean (SD) usability score was
77.0 (14.18). Conclusion: The results were promising as they showed that Gigiku Sihat had
a good usability. Thus, the development of this mobile application focusing on diet and
oral health served as a new source of oral health education and provided a necessary
foundation in developing future improved mobile application development for parents in
the prevention of early childhood caries.
