The aim of the present study is to investigate the electrochemical behaviour of orthodontic wires in artificial saliva with and without bacteria. Four factors were considered to characterize the bacteria present in the saliva, viz. urban and rural groups of vegetarians and non-vegetarians. The results showed that among the heterotrophic bacterial isolates, Gram-positive species dominated over t...

CoCrMo alloys are known for their biocompatible properties, which, together with favorable mechanical mean they can be efficiently used in dentistry. With the development of selective laser melting fabrication 3D printed objects, interest corrosion properties this alloy has risen field prosthodontics. In study, CoCrMoW dental were studied artificial saliva at body temperature i.e. 37 °C. Differ...

OBJECTIVE The aim was to investigate the in vitro fluoride release from fluoride varnishes under acidic conditions. STUDY DESIGN Poly(methyl methacrylate) blocks (Perspex, n=3 per group) were painted with 80 ± 5 mg fluoride varnish (n=10) and placed into artificial saliva for 30 min. Then, blocks were placed into either 1% citric acid (pH 2.27) or 0.3% citric acid (pH 3.75) solutions (n=3 per...

AIM The aim of the present study was to evaluate the in vitro caries preventive effect of fluoridated orthodontic resins under pH cycling with two types of acid demineralizing saliva. MATERIALS AND METHODS Brackets were bonded to 120 extracted human premolars, using Rely-a-bond (n = 40), Tru- Bond (n = 40) and Ortho-one (n = 40) orthodontic bonding agents. Each group of resin was divided into...
