House committee substitute makes the following changes to 1st edition. Amends GS 116-40.10 to require the Board of Governors to forgive a dental scholarship loan if, within seven years after graduation, the recipient practices dentistry in a rural or underserved area of the state for four years (current law requires only practicing dentistry in the state for four years). Further amends the statute by removing proposed language limiting loan forgiveness to loans awarded to a study who graduated from the UNC-Chapel Hill School of Dentistry.
