Dental age is an important indicator of biological age and has essential application value in orthodontics, forensic dentistry, and criminal investigation. Traditional methods of dental age evaluation include atlas, scoring, and pulp cavity evaluation. These manual evaluation methods are relative cumbersome that their applications have been hampered. With the development of artificial intelligence technology and machine learning algorithms, intelligent evaluation of dental age have been gained more attention in recent years. This paper aims to provide a reference for the future research and application of dental age evaluation, summarize traditional and machine learning methods, and demonstrate the benefits and limitations of the existing approaches that are used in this topic.

Key words: dental age, dental age assessment, machine learning, artificial intelligence
