Comparative Evaluation of Antibacterial Activity of Chlorhexidine, Povidone Iodine and Glutaraldehyde for Disinfection of Orthodontic Appliances - An In-Vitro Study

Introduction: Orthodontist must take precautionary measures to protect patients from cross-infection by contaminated materials received the manufacturers. To minimize incidence of prior bonding an invitro study was done assess antibacterial activity chlorhexidine, povidone iodine and glutaraldehyde. Aim: compare 2% 5% glutaraldehyde on orthodontic bonding. Materials methods: A total 36 samples were included in this study. The main group consists 3 disinfectants one control (n =4). Group -1(Chlorhexidine gluconate), - 2 (Povidone Iodine), (Glutaraldehyde) 4 (Control –untreated). Each subgroups tested namely (brackets), B (archwires) C molar bands (n=9). which bacterial species streptococcus, staphylococcus, lactobacillus number colonies counted before disinfection. subjected disinfection with chlorhexidine for 5 minutes Povidone Iodine 10 minutes. 20µl sample disinfected incubated after Results: There no formed when used disinfect archwires molarbands few samples. not effective against species. compared gluconate all three Streptococcus, Staphylococcus Lactobacilli obtained p-value is < 0.001 statistically significant groups overall. Conclusion: Disinfection most
