If your committee was helpful and effective you will pass your defense, they should have given you enough direction to guide you to passing this right of passage. When I did my dissertation defense it was so cool cause when I was done my committee asked me to leave the room, then when they called me back in my chair said "Dr, would you please come in"? Traditionally, it is at this moment when you can be addressed as Dr. for the first time. Cool.
Good luck!
