1. Early orthodontic treatment of malocclusion in children: I am proficient in diagnosing and treating various types of malocclusion in children at an early stage, including anterior crossbite, crowding, deep overbite, open bite and other common pediatric orthodontic problems. Combining the growth and development characteristics of children's maxillofacial region, I formulate personalized early intervention plans, adopt appropriate orthodontic appliances to guide the normal growth of jaws and teeth, correct bad oral habits, and lay a solid foundation for the subsequent occlusal development and facial aesthetics of children.

2. Alveolar surgery for children such as supernumerary teeth: I have rich clinical experience in pediatric alveolar surgery, especially in the diagnosis and surgical treatment of supernumerary teeth in children. I am skilled in handling various complex cases of supernumerary teeth (including impacted supernumerary teeth, ectopic supernumerary teeth, etc.), and adopt minimally invasive surgical techniques to minimize surgical trauma, reduce postoperative pain and swelling of children, and ensure the safety and effectiveness of the operation. In addition, I am also proficient in other common pediatric alveolar surgical procedures, providing comprehensive surgical support for children's oral health.

1. Application of calcium-silicate-based biomaterials in children's dentistry: Focusing on the development and clinical application of calcium-silicate-based biomaterials, exploring their biocompatibility, bioactivity and repair effect in children's oral tissue regeneration, so as to provide safer and more effective material support for the treatment of children's oral diseases.

2. Application of artificial intelligence technology in children's dentistry: Devoted to exploring the application value of artificial intelligence technology in the diagnosis, treatment and health management of children's oral diseases, including intelligent diagnosis of pediatric dental caries, auxiliary design of orthodontic treatment plans, and prediction of maxillofacial growth and development, so as to improve the accuracy and efficiency of pediatric oral diagnosis and treatment.
