How was it dismissed? Expunged? Dismissed outright in court? In either respect, if you were arrested and it ended up in court, it's going to be on your record, even if it was dismissed. It shouldn't cause you any problems, though it depends on where you are traveling to. Some countries, like Canada, will bar people with criminal records from entering into their country, so it really depends on how it was dismissed.
I doubt you'll have any problems. Good luck to you.
