ABSTRACT

Recent studies have shown that 50% to 75% of all orthodontic patients develop demineralization on the labial surface during fixed appliance therapy.
The aim of the present study is the measuring of fluoride concentration in saliva at the patient under fixed orthodontic treatment with metal braces by using two different types of orthodontic adhesives –composite and resin-reinforced glass ionomer cements. Subjects for this study were 60 patients scheduled for orthodontic therapy in the Department of Orthodontics,University Clinic of Dentistry “St. Pantelejmon” – Skopje. Patients were divided in two groups according to adhesive type using for bonding: -First group formed 30 patients which braces were bonded with composite adhesive -Second group formed 30 patients which braces were bonded with resin-reinforced glass ionomer adhesive (RRGICs).
The results showed that resin-reinforced glass ionomer adhesive (RRGICs) release fluoride one day after bonding the braces and rapid decrease of fluoride concentration in saliva one month later. The situation was otherwise at the patients with composite adhesive where we have a slow decrease of fluoride concentration at T1 period.
