Decay or Not Decay: The Dental Sealant Controversy

http://vitals.nbcnews.com/_news/2012/05/04/11524617-decay-dilemma-do-kids-need-dental-sealants?lite

This particular article, which was found in nbcnews.com (Decay dilemma: Do kids need dental sealants?), deals with the subject of dental sealants, which are used to close cavities in teeth, for children and analyzes whether it is better to get the sealants to stop the cavities and risk obtaining side effects from it or to leave the cavities alone. This topic interests me in a personal level since I have lived with a dentist for my entire life (my father) and since I am trying to discover what kind of doctor I want to be.
