BackgroundWith the increased use of smartphones, mobile applications (apps) aimed at promoting healthy behaviors have experienced exponential growth. ObjectivesThis study aimed to provide an overview of mobile apps that use gamification to motivate children to maintain optimal oral hygiene and to evaluate the quality of the oral hygiene apps for children (OHACs) available in the Turkish Google Play Store and the Apple Store. MethodsBetween January 20 and February 2, 2024, OHACs were searched in the Turkish Google Play Store and the Apple Store. Seven apps were assessed using the Mobile Application Rating Scale (MARS) and evidence-based dentistry criteria (EBD). We used Microsoft Office Professional 2016 (Microsoft Excel 2016; Microsoft Corp, Redmond, WA, USA) and IBM SPSS Statistics version 29 for Windows (IBM Corp, Armonk, NY, USA) for all the data analyses and visualizations. ResultsThe best overall MARS scores were obtained for Diş Doktoru: Dentist (3.53 ± 0.15) and Diş Hekimi Oyunları: Dentist Game (3.72 ± 0.33). The worst overall MARS scores were obtained for Truthbrush (2.76 ± 0.06) and Mimizaur (2.85 ± 0.09). Hayvan Diş Hekimi: Animal Dentist, Diş Hekimi Oyunları, and the Brush Teeth Game: Kids Dentist included the most evidence-based content. ConclusionMost OHACs achieved moderate MARS scores for promoting oral hygiene habits among children. Improving the quality and educational content of OHACs could increase personal oral care motivation in children. More research is required to determine the long-term effects of the apps and whether they align with oral hygiene guidance.
