Smart Smiles in “Go Go Brush” App.: Technical and Clinical Insights into an Arabic Preschooler-Friendly Oral Hygiene Mobile App.

Background: /Objectives: Oral hygiene is crucial to preventing dental caries. However, many preschool children fail to maintain proper oral hygiene practices due to a lack of assistance from parents and dentists because tooth brushing seems too lengthy and tedious. The goal of this article is to design a gamified mobile application called "GoGo Brush" that will appeal to Arab preschoolers and verify its effectiveness in enhancing their oral condition and their parents' knowledge. Methods: There were two groups: a study group of 122 children and parents, and a control group of 50 children. Parents in the study group filled in questionnaires, and all children received toothbrushes and education on oral hygiene. Plaque and gingival indices were measured. The study group was introduced to the GoGo Brush app and a video on plaque removal. The app's effectiveness was assessed over one week and one month. Changes in plaque and gingival status were noted. Researchers also conducted a usability evaluation of the app. Results: The app led to significant improvements in plaque and gingival indices after one month compared to the baseline and control groups. Plaque scores decreased from 2.41±0.28 to 0.695±0.25 (p
