De Grouchy syndrome or Distal 18q- is a genetic condition caused by a deletion of genetic material within chromosome 18, and the deletion involves the distal section of 18q. It causes a wide range of medical and developmental concerns. Congenital orthopedic anomalies, cleft lip and palate are relatively common. People with distal 18q- are often small for their age. Most individuals with distal 18q- fall in the mild to moderate range of intellectual disability. Strabismus and nystagmus, changes in the optic nerve as well as colobomas are also fairly common. People with distal 18q- frequently have conductive and/or sensorineural hearing loss. At present, treatment for distal 18q- is only symptomatic. This article presents a case report: Caries treatment of a 4-year-old female patient with de Grouchy syndrome under general anesthesia. The special considerations of dental care, especially caries treatment for the patient with de Grouchy syndrome are discussed.
