Abstract
Maximum mouth opening is regarded as an important tool used to evaluate the clinical function of temporomandibular joint and the masticatory system. It has been reported that children can also exhibit severe dysfunction or pain in some cases of temporomandibular disorder. The purpose of this study was to measure the normal maximum mouth opening in Korean children and to analyze the correlations between mouth opening and the associated factors. Maximum mouth opening was measured from 151 healthy children between the ages of 2 and 6 years old. Age, height, weight, and mouth width were also recorded. As a result, the mean maximum mouth-opening was $37.72{\pm}5.10mm$. While the values were greater in boys than in girls without statistical significance, the increases of maximum mouth opening based on age, height, weight, and mouth width were significant (p < 0.05). In children, positive correlation coefficients were observed between maximum mouth opening and the associated factors and height showed the highest correlation. In conclusion, we collected data of the normal range of maximum mouth opening in Korean children, and this study can be utilized as a basis in diagnosing pediatric temporomandibular disorder and safety standard of mouth opening during dental procedures.
