Video game playing and oral health in school-age children: A cross-sectional study in Turkey

The aim of this study is to evaluate the relationship of video game playing with oral/dental health and harmful oral habits in school-age children.

The daily video gamer (n = 77) and occasional video gamer (n = 77) children between 6 and 12 years old were included in the study. A questionnaire inquiring socio-demographic characteristics, video gaming and abnormal oral habits of the children was filled by parents. The children were examined intraorally and decayed-missing-filled tooth, the International Caries Detection and the Assessment-II System scores, dental plaque and gingival indices were recorded.

Of the children; 42.9% daily video gamers played video games for between 1 and 2 h and 57.1% played for ≥2 h while all of the occasional video gamers spent for between 1 and 2 h on video game per day. The daily video gamer and occasional video gamer children were not different in terms of socio-demographic characteristics, frequency of having daily tooth brushing habit, using children's toothpaste and having regular dental checkup (P > 0.05). No statistically significant difference was present between the groups in terms of frequencies of abnormal oral habits and having at least one abnormal oral habit (P > 0.05). Severe gingivitis and advanced caries lesions were more common in daily video gamer group (14.2% vs. 3.9%, P = 0.025 and 90.9% vs. 70.9%, P = 0.026, respectively). Daily video gaming time was weakly correlated with plaque index (r = 0.26, n = 77, P = 0.024). Daily video gaming for ≥2 h increased the risk for severe gingivitis (odds (95% confidence interval) = 4.53 (1.07-19.23), P = 0.041) while daily video gaming for between 1 and 2 h decreased the risk for having abnormal oral habit (odds (95% confidence interval) = 0.39 (0.16-0.93), P = 0.034).

In school age, daily video gaming may worsen oral and dental health compared with occasional video gaming. Particularly, an excessive video gaming time seems to be associated with poor oral health in school children.
