Comparison of Antimicrobial Efficacy of Custom-Made Orthodontic Adhesives- A Double Blinded In-Vivo Study.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 3
Abstract
Introduction: This double blinded study was designed to investigate the antimicrobial efficacy of three custom modified antimicrobial orthodontic adhesive against the bacterial load of Streptococcus mutans around orthodontic brackets over 28-days period. Materials and Methods: A total of 56 teeth from 14 male prospective orthodontic patients in the age group of 15-30 years were drawn for the study. The samples were divided into four groups, Group 1 contains Transbond XT primer, Group 2 contains Transbond XT modified Cetylpyridinium Chloride, Group 3 contains Transbond XT modified Triclosan and Group 4 contains Transbond XT modified Sodium Fluoride. Transbond XT primer was modified by addition of 2.5% Cetylpyridinium chloride, 0.3% Triclosan and 2% Sodium fluoride using a magnetic stirrer. Buccal surface of maxillary and mandibular lateral incisors was etched with 37% phosphoric acid gel and modified and control primers were applied over the etched surface and light cured. Metal brackets were bonded directly using Transbond XT composite and modules were engaged over it. On day 1,7 and 28 the modules were collected from the brackets for the bacterial count. The bacteriological study was conducted by Dilution Plating Method at baseline, 1st day, 7th day and 28th day. Results: On intragroup comparison all the antimicrobial agents showed maximum activity at day 7. Upon intergroup comparison at 1st Day, 7th Day and 21st Day, maximum antimicrobial activity was seen in Sodium Fluoride, Triclosan and Cetylpyridinium Chloride group respectively. Conclusion: The performance when judged over the total study period of 28 days indicates all modified primer showed effective antimicrobial activity and among them Triclosan had the better antimicrobial action in primer against Streptococcus mutans.
