Abstract

Background:  Dental plaque is defined clinically as a structured, resilient, yellow- grayish substance that adheres tenaciously to the intraoral hard surfaces, including removable & fixed restorations. Materials and methods: 48 patients between age of 14 – 20 years were scheduled for fixed orthodontic treatment with MBT 0.022 slot. Patients inclusion and exclusion criteria was differentiated based on various parameters. Two groups with random allocation of bracket type as Mini conventional and Standard conventional.  24 patients were included in each group with 8 patients included in each subgroup. Microbial and periodontal records were obtained on the day of bonding (T0) and 1 month after bonding (T1).  Results: Standard brackets showed high values for colony count of both S mutans, lactobacillus and periodontal parameters than mini brackets from all the manufacturers.  Conclusion: The size of the bracket increases, the inter bracket distance decreased hindering with proper oral hygiene maintenance leading to increase in plaque accumulation and microbial colonization.
