A new material for filling teeth that releases hydroxyl ions and a preventive gel with buffering substances can both effectively neutralize the acid produced in tooth plaque, even after being in the mouth for a long period. This has been shown by Anitha Persson at Umeå University in Sweden.
Caries, or tooth decay, both in connection with fillings in adult individuals and in the form of new cavities among the aging population of Sweden, is a growing problem. Preventing caries is one of the chief objectives of dental care today.
Anitha Persson has studied two ways of neutralizing the acid formed in tooth plaque following the ingestion of carbohydrates. This would prevent new caries attacks. A new material for filling cavities proved to be capable of effectively neutralizing acid production in plaque, even after a long period in the patient’s mouth. Regular application of a fluoride gel containing buffering substances should be able to inhibit caries in elderly patient, unless they suffer from dryness of the mouth.

On friday 15th of december Anitha Persson, Inst. of Odontology, Dental Hygienist programme/oral health, her thesis with the title ”In vivo evaluations of the neutralizing effect of a hydroxyl ion-releasing resin composite and a prophylactic gel on plaque acidogenicity measured by the mictrotouch method”.
The dissertation is held kl. 9.00 sal B, 9 tr., Tandläkarhögskolan, NUS. Faculty opponent is docent Anette Oliveby, cariology, Faculty of Odontology, Karolinska institute, Stockholm.
