Robert Sinclair had his teeth cleaned and polished free Saturday by dental hygienist Karen Preston of the Utah Dental Hygienists Association, which provided the service to children at the Salt Lake Family Homeless Shelter. The service was under the supervision of area dentists who are part of the Salt Lake Donated Dental Services Clinic. The clinic provides dental care to individuals whose income falls below poverty level and who don't qualify for Medicaid. Twelve Rotary Clubs help sponsor the clinic, which is also supported by five dental supply companies and four laboratories. Those interested in contributing financial support or other services to the clinic should contact clinic coordinator Connie Moore, 534-1500.
