What congenital anomalies do patients with Downs Syndrome present with ?





A low powered study from Brazil has illustrated some evidence for hypodontia being highly prevalent amongst patients with Downs Syndrome. In this study 96 individuals were clinically and radiographically examined. 

Hypodontia was found to be the most prevalent condition at 36%, followed by microdontia at 10%, conical teeth at 7%. Taurodontic teeth were rarer at 3% with other anomalies such as dens invaginatus 1% of cases. 

The authors concluded that the occurrence of hypodontia was high amongst this patient cohort and is likely to impact on their management not only in their interaction with orthodontics and paediatric dentistry but also with special care dentists managing them in adulthood.

Hypodontia in orthodontically treated children

The frequency of hypodontia in orthodontically treated children, both male and female, and the association between tooth type, the upper or lower arch, the affected side and Angle’s classification were studied using interviews, oral, study cast and panoramic radiographic examinations of 212 patients with a mean age of 12 years 7 months. A hypodontia frequency of 11.3 per cent was found for the total sample. This was higher than the incidence of hypodontia reported in other studies of orthodontically treated children. The most frequently missing teeth were the maxillary lateral incisors, and maxillary and mandibular second premolars. The missing teeth were more often absent on the right (54.2 per cent) than on the left (45.8 per cent) side, in both males and females. One tooth was absent in 29.2 per cent of patients, two in 58.5 per cent, but seldom three or more. Orthodontic space closure was the treatment of choice in 87.5 per cent of the subjects.
