Enamel demineralization around orthodontic attachments is a common complication of orthodontic treatment with fixed appliances. Plaque accumulation and plaque maturation, colonization of bacteria around the orthodontic attachments, presence of a susceptible tooth surface and duration of orthodontic treatment are reported to be factors that play a role in demineralization. Orthodontic adhesive resins that are used for bonding appliances to teeth are one of the risk factors for enamel demineralization during orthodontic treatment That is why some agents with antibacterial properties are now being added to orthodontic adhesive resins. Cetylpyridinium chloride, zinc oxide, triclosan, benzalkonium chloride and silver are the antibacterial agents that were added to restorative resins as well as orthodontic adhesives and their effects have been evaluated. If they prove to be viable, these new orthodontic adhesives may help with the prevention of white spot lesions along with other preventive measures such as mechanical plaque control and topical fluoride application. Our aim is to review the available literature on these new additives with special emphasis on their antimicrobial activity and effect on adhesive properties.

Ortodontik ataçmanların etrafında görülen mine demineralizasyonu sabit apareylerle yapılan ortodontik tedavinin en yaygın komplikasyonudur. Demineralizasyonda rol oynayan faktörler arasında plak birikimi ve olgunlaşması, ortodontik ataçmanların etrafındabakteri kolonizasyonu, demineralizasyona yatkın diş yüzeyi bulunması ve ortodontik tedavinin süresi sayılmaktadır. Mineye braketleri yapıştırmak için kullanılan ortodontik adeziv rezinler de mine dekalsifikasyonuna yol açabilecek olası risk faktörleri arasındadır. Bu nedenle antibakteriyal özellikleri olan bazı ajanlar ortodontik adeziv rezinlere eklenmeye başlanmıştır. Bu antibakteriyel maddelerden setilpiridinium klorid, çinko oksit, triklosan, benzalkonyum klorid ve gümüş restoratif kompozit rezinlerin dışında yaygın kullanılan ortodontik adeziv rezinlere de eklenerek özellikleri incelenmiştir. Eğer kullanımlarının uygun olduğu gösterilebilirse, bu yeni ortodontik adezivler topikal florür uygulaması ve mekanik plak kontrolü gibi diğer koruyucu önlemlerle beraber beyaz nokta lezyonlarının önlenmesine yardımcı olabilirler. Bu derlemenin amacı, demineralizasyonun önlenmesinde yardımcı olabilecek bu yeni katkı maddeleriyle ilgili mevcut literatürü antimikrobiyal aktivite ve adeziv özellikleri üzerindeki etkileri yönünden değerlendirmektir.
