Dr. Fontana featured on ADA Facebook event

Dr. Margherita Fontana

Sealant guidelines topic of first-ever ADA live FB chat

Ann Arbor, Mich., Feb. 21, 2017 -–  School of Dentistry faculty member Dr. Margherita Fontana was featured Wednesday, Feb. 22, in the first-ever live Facebook chat by the American Dental Association.

Fontana discussed the use of sealants to protect the teeth of children and adolescents from cavities. She was joined by U-M alumnus Dr. Suhail Mohiuddin (DDS 2010), one of the owners and a dentist at Dentologie, a practice based in Chicago.

The Facebook Live event was archived by the ADA and can be viewed here.

Fontana was part of a panel of experts convened last year by the ADA Council on Scientific Affairs, in collaboration with the American Academy of Pediatric Dentistry, to study the effectiveness of sealants and to create an updated set of guidelines for their use.  The resulting ADA guidelines, published in the Journal of the American Dental Association, are recommended for dentists across the country.

The study’s three main conclusions:
   • Sealants are effective in preventing and arresting pit-and-fissure occlusal carious lesions of primary and permanent molars in children and adolescents compared with the nonuse of sealants or use of fluoride varnishes.
   • Sealants could minimize the progression of noncavitated occlusal carious lesions (also referred to as initial lesions) that receive a sealant.
   • Based on the available limited evidence, the panel was unable to provide specific recommendations on the relative merits of one type of sealant material over the others.

Fontana, a professor in the Department of Cariology, Restorative Sciences and Endodontics, has an extensive clinical research background in childhood caries management.  Among her current projects is overseeing U-M researchers in the Michigan Caries Prevention Program, now in its third year as a comprehensive interprofessional program to improve oral health for the state’s children, with an emphasis on improved collaboration between dental and medical professionals.

More about the ADA-developed sealant guidelines are on the organization’s website.
