| Abstract | ||
| Plaque and enamel demineralization can occur when orthodontic archwires are present in the oral cavity because they provide a unique surface for bacterial adhesion. Bacterial biofilm plays a major role in the development of complications such dental caries and periodontal disease. The purpose of the study was to examine the effect that an esthetic surface coating of NiTi archwires would have on the adherence of mutans streptococci. Material and method: three types of coated NiTi archwires (rhodium, gold and flexy blue) and one uncoated NiTi archwire with round cross section 0.016 inch were tested in the current study. Five pieces of each types of archwire were incubated in phosphate-buffered saline for two hours. Then, these wire segments were immersed for 5, 90, and 180 minutes with mutans streptococci suspension to conduct the bacterial adhesion assay. Result: there were statistically significant differences in the degree to which bacteria adhered to the various archwires at each time interval, with the level of adhesion being statistically highest on the uncoated NiTi wire and the level being statistically lowest on the gold-coated NiTi wire (p < 0.05). The result showed that the highest bacterial adhesion in 180 min followed by 90 min and the lowest in 5 min. A positive correlation was detected between bacterial adhesion and incubation time. Conclusion: the esthetic surface coating were influence the biofilm adhesion on the archwires, gold coated significantly decrease mutans streptococci adhesion when compare with uncoated NiTi wire. Higher incubation time increased the number of bacterial adherence for all types of archwires. | ||
