Abstract

Introduction: White spot lesions and gingivitis are most common sequlae of fixed orthodontic appliance therapy. Studies have revealed that silver nanoparticles have antimicrobial property against bacteria, fungi and protozoa.
Aim: To assess antibacterial property of silver coated stainless steel orthodontic brackets against S. mutans, L. acidophilus, P. gingivalis.
Material and Method: This experimental study was carried out in 120 stainless steel orthodontic brackets, out of which 60 brackets were silver coated, 60 brackets were uncoated. These brackets were tested for its antimicrobial property against S. mutans, L. acidophilus and P. gingivalis. Antibacterial property of silver coated stainless steel brackets measured by bounting colony forming unit (CFU). Antibacterial property of silver coated brackets against P.gingivalis demonstrated by reduction in optical density.
Results and Conclusion: These data were statistically analyzed and it was concluded that Silver coated stainless steel orthodontic brackets shows more antibacterial activity against S. mutans, L. acidophilus and P. gingivalis compared to the control group. Silver coating of stainless steel orthodontic brackets can be used to prevent development of dental plaque, there by controlling the dental caries and periodontal disease.
Keywords: White spot lesions, Nanoparticles, Antimicrobial.
