calculus, periodontium
ADVERSE EFFECTS, PLAQUE
After the completion of the fixed orthodontic treatment, outcome stability is assumed as a great challlenge.Fixed retainers provide retention for prolonged time, and are the most common choice for the mandibular arch.Fiber-reinforced composites (FRC) are innovative materials with excellent splinting properties, composed of multiple fibers made up of carbon, polyaramid, polyethylene and glass.Despite of all the gains, fixed retainers are criticized for causing adverse effects on the health of periodontium due to the accumulation of plaque and calculus.Thus, the present study tested the null hypothesis that there would be no significant difference in the health of periodontium between the patients with FRC and MSW fixed retainers.
