Douglas H. Mahn, D.D.S., a periodontist and resident of Little Rocky Run, has had his 40th article published in a peer-reviewed dental journal. His articles have covered topics including dental esthetics, gum grafting and dental implants. Mahn's most recent article was published in the November issue of Clinical Advances in Periodontics, the official online journal of the American Academy of Periodontology. This article covers the treatment of dental implant infections (peri-implantitis). Mahn said, "What makes this article so important is that infections involving dental implants are on the rise. Patients often do not know they have a problem until it is too late. Dentists need to know how to recognize implant problems and what treatments are available once they occur." His periodontal and implant practice is in Manassas. See www.douglashmahndds.com.
