ABSTRACT
Tetralogy of Fallot (TOF) is one of the most serious cyanotic congenital heart diseases and is characterized by common systemic and oral findings. This study was carried out on 30 patients (3−13 years old) with TOF and 30 subjects as a control group. The patients were examined for oral hygiene, mucous membrane, gingivae, dental caries and any hypoplasia. There appeared to be an increase in dental caries, hypoplasia and periodontal disease in the patients with TOF compared with controls. The dental aspects of TOF patients are highlighted and their dental management is discussed.
