Pediatric dentistry should focus not only on the treatment of various oral diseases during the entire growth and development of children but also on the early prevention, diagnosis, and intervention of various oral diseases in this process. Early identification and removal of risk factors or early intervention for common oral diseases is necessary to the implemen-tation of oral health management for pregnant women, infants, preschool and school-age children, and adolescents with diffe-rent general and oral physiological characteristics and common oral diseases. The treatment enables the growth and develop-ment of the teeth, as well as occlusion and facials along the normal trajectory, ultimately achieving the functional perfection and aesthetic coordination of the cranio-maxillary and occlusion.
