GLANZMANN'S THROMBASTHENIA WAS REPORTED and described as a bleeding di
athesis seen in children and characterized by diminished clot retracti
on. It is an autosomal recessive bleeding disorder. The disease is mar
ked by frequent mucocutaneous hemorrhages either due to defective func
tion of the platelets or lack of fibrinogen binding membrane receptor
glycoproteins IIb/IIIa which are located on the surface of the platele
ts. Case reports on 3 siblings, a girl of 11, and 2 boys of 12 and 16
years old with Glanzmann's thrombasthenia are reviewed. The major comp
laint of the patients was gingival bleeding. Periodontal treatment was
performed under platelet transfusion and proper oral hygiene instruct
ion was given. The patients were followed for 6 months and no periodon
tal complications developed during this time. Proper periodontal care
for such patients is essential both fur local and systemic health.
