Abstract

Objective: To investigate the effect of different types of orthodontic brackets on growth and adherence of microorganisms in oral flora Streptococcus mutansand Lactobacillus.
Method: Invivo study a total of 10 patients for fixed orthodontic treatment were selected and bonding of the brackets was done randomly in each quadrant with split mouth technique giving a total sample of 40. Sample were divided into 4 equal groups based on bracket type & use: Mini Master Stainless steel brackets, Silkon Plus TM Plastic brackets, Radiance PlusTM Ceramic
brackets,Titatinumorthos. After one month, the brackets were then debonded and collected in a sterile medium for microbiological study. The microbial colonies were counted and all data was analyzed through one way ANOVA and Tukey-Kramer test.
Result:The data analysis showed there was no significant difference in adherence of Lactobacillus and Streptococcus mutans on titanium and plastic brackets whereas, significant difference present in retention of Lactobacillus among all the other groups of bracket.
Conclusion:The titanium brackets have the highest microbial adhesion due to its surface roughness and there was also a close relevance in adhesion of S.mutans to plastic and ceramic bracket groups. For patients primarily at increased risk of dental caries or periodontal diseases, or both, microbial adhesion could be a significant determining factor in the selection of orthodontic brackets.

Keywords: Fixed orthodontic appliance, lactobacillus, streptococcus mutans, colony forming unit.
