Comparison of Rate of Canine Retraction and the Efficiency of Reducing Plaque Accumulation Using Zirconia Nanoparticle Coated Orthodontic Bracket on One Side and Conventional Stainless Steel Orthodontic Bracket on the Other Side A Split Mouth Study

Abstract

Aim and Objective newlineThe aim of this study is to compare the rate of canine retraction and visual plaque newlineaccumulation when we use zirconia nanoparticle coated orthodontic brackets as newlinecompared with uncoated conventional orthodontic bracket. newlineMaterials and Methodology newlineThe study was designed as a split mouth prospective quasi randomized control trial, newlinewhich included 10 patients above the age of 15 years, requiring first premolar newlineextractions. After levelling and aligning, the zirconia nanoparticle coated orthodontic newlinebracket was bonded to the right maxillary canine. Anchorage was reinforced using newlinemini implants between the second premolar and first molar. newline9 of 106 newlineIndividual canine retraction was done using closed coil spring in 19*25 ss wire. newlinePatient was recalled every 28 days for 3 months. Serial models were taken at every newlinefollow up visit. newlineResults newlineAn independent t test showed a significant difference between both the groups for newlineamount of canine retraction and rate of canine retraction. There was minimal newlineanchorage loss. Wilcoxon signed rank test between the groups showed significant newlinedifferences for visual plaque score between the two groups. newlineConclusion newlineThere is a significant difference between the zirconia nanoparticle coated newlineorthodontic bracket and uncoated conventional bracket for amount of canine newlineretraction, rate of canine retraction and visual plaque scores during retraction. newline
