I believe pinworms are species-specific and pose little threat, but as canine roundworms and hookworms can cause very serious disease, especially in children.... I would say Yes, if for no other reason than to err on the side of caution. Good hand washing should protect you, your family and the little urchins at school. You would have a hard time talking an angry parent out of blaming you if they found out your tortoise had pinworms and then their child came down with them, even if you could show them tons of proof as to the species specificity of the parasite.
