Does A Sealed Bracket Kit Give Sterility Check???
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 5
Abstract
Introduction: Orthodontic brackets are classified as semicritical instruments. However, in orthodontic clinical practice, the use of brackets directly from non-sterile manufacturer’s packages is still a routine. In this scenario, it becomes extremely important to assess the potential contamination of these materials so as to determine sterilization protocols and maintain the health of patients and dental practitioners. Objective: To evaluate the microbial contamination of orthodontic brackets as received from the manufacturer using microbiological tests. (An in vitro study) Materials and Methods: The sample comprised 25 brackets of five different commercially available brands, used directly from the manufacturer’s packaging, divided into 5 groups (n =05 brackets each). Materials were tested under aseptic conditions to detect bacterial growth using microbiological tests and analyze types of bacteria present by preparing slides using gram staining protocol. Results: In four of five groups the brackets showed microbial contamination: group A, 3M Unitek metallic brackets, group B, TP Orthodontics metallic brackets, group D Forestadent self ligating metallic brackets and group E,3M Unitek ceramic brackets. Microbiological analysis showed presence of endospore forming bacilli. Group C, OrthoOrganisers metallic brackets showed no contamination. Conclusion: Brackets of three brands (TP Orthodontics, 3M Unitek and Forestadent) were found to be contaminated by bacteria in the original packages supplied by the manufacturers, which suggests a risk for patient contamination. These data suggest that the manufacturers of these materials should improve the quality control of the packaging used, including sterilization, for the security of patient health.
