This discipline focuses on pediatric/adolescent growth and development, disease causality and prevention, child psychology and management, and all aspects of the highly-specialized Pediatric restorative techniques and modalities. Some pediatric dentists also specialize in the care of "special needs" patients, such as people with cerebral palsy, mental retardation and autism. Pediatric dentistry emphasizes the establishment of trust and confidence in children with their dentists. Consequently, one of the main components of pediatric training is child psychology. This manifests itself in special office designs, different communication styles and an emphasis on teaching preventative dental habits to children in an effort to make dental visits enjoyable.
