概要	We aimed to reveal whether the prevalence of incompetent lip seal (ILS) varies with age and region, as well as to clarify the factors related to an ILS, in a large-scale epidemiological study.We observed that 30.7% of Japanese children exhibited an ILS and that the ILS rate increased with age (p < 0.001). There were no regional differences in the rate of ILS . We revealed that 12 of 44 survey items exhibited a statistically significant correlation with ILS (p < 0.001). The rate of ILS seems to increase with age in children. Therefore, this disorder may not self-correct during the growth periods in these children.
