TO ASSESS THE MICROBIAL CONTAMINATION OF ORTHODONTIC BUCCAL TUBES, ARCH WIRES AND BRACKETS FROM VARIOUS MANUFACTURERS - AN INVITRO STUDY
Introduction: Orthodontic fixed appliance therapy is one of the common treatment modes for treating different types of malocclusions. Knowing the micro biota that colonizes the unused orthodontic appliances is important for implementing specific sterilization and disinfection measures before the start of treatment.
Aims and Objectives: The aim of the present study was to assess the microbial contamination of orthodontic Buccal tubes, Arch wires and Brackets from various manufacturers.
Material and Methods: The study included 6 Buccal tubes, 6Arch wires and 6 Brackets belonging to 4 different manufactures which were divided into 12 specimen groups for microbiological culture. The number of colonies appeared were counted and enumerated in the form of (colony forming unit) cfu/ml and were subjected to SEM analysis for the detection of bacteria.
Results: The results showed highest cfu/ml in American orthodontics (AO) brackets accounting for 08 cfu/ml, 04 cfu/ml in 3M Arch wires and 02 cfu/ml in AO Buccal tubes, the remaining samples did not show any colonies.
Conclusion: Hence study highlights the need for manufacturers to state the sterility of their products and for practitioners to ensure the sterility of materials before use and not to assume that all items are sterile.
