I didn't look at the website but I have gone on a humanitarian type trip before and I actually performed numerous extractions and fillings. I went to Peru in 2005 in hopes that the experience would help my application and my chances of getting into dental school. Which brings me to now, my second application cycle and still not going to get in. In other words these experiences are good for your application but if you think that they will be a large factor in determining whether or not to accept you, your wrong. I do believe that the personal experience, exposure, and knowledge is beyond measure. But I don't personally believe it will do a whole lot for your application. Granted this is my own experience and personal opinion. I could be wrong.
