[Periodontal Disease in Noonan's Syndrome]

Two cases of non-related patients suffering from Noonan syndrome with characteristic data of the syndrome, had clinical and radiological evidence of very advanced periodontal disease. This disease seems to be unjustified because of the patients age and the lack of irritating local factors or systemic illnesses. A review of the literature showed no evidence of the periodontal disease as part of the syndrome.
