ABSTRACT

Objectives: This study aimed to examine the associations between smartphone overdependence, health behaviors, and oral symptom experience among adolescents. Methods: Data from the 19th (2023) Korea Youth Risk Behavior Survey were analyzed for 48,990 participants. Complex sample analysis and multiple logistic regression were conducted to examine the associations between smartphone overdependence, health behaviors, and oral symptom experience. Results: Smartphone overdependence was significantly associated with an increased risk of tooth fracture, chewing discomfort, tooth pain, and gingival bleeding. Lower toothbrushing frequency was associated with increased risks of chewing discomfort, tooth pain, and gingival bleeding. Adolescents who slept less than 7 hours showed higher risks of chewing discomfort and tooth pain, while an inverse association was observed for gingival bleeding. Conclusions: Smartphone overdependence and health behaviors were associated with oral symptom experience among adolescents. To improve oral health, an integrated approach is needed that includes appropriate smartphone use, sufficient sleep duration, and improved personal hygiene behaviors.
