dc.description.abstractPurpose: To compare adhesive flash-free (FF) and adhesive pre-coated (APC) brackets in terms of plaque retention and constituents, gingival biomarkers and enamel demineralisation. Materials and Methods: Fifty adolescents (mean age +/- SD; 14.23 +/- 0.15 years, age range: 13-18 years) were randomly distributed to receive FF or APC ceramic brackets in the maxillary right or left quadrant. Plaque and gingival indices, quantitative light-induced fluorescence (QLF) imaging, gingival crevicular fluid (GCF) and plaque sampling were performed at baseline and at 1, 2 and 3 months (T-0, T-1, T-2, T-3) after bracket placement. QLF was repeated following debonding. GCF samples were analysed for biomarkers by immunoassay and plaque by real-time PCR for bacterial content. Data were analysed using the Wilcoxon test on dependent samples and 2-tailed ANOVA. Results: Plaque index, gingival index and fluorescence changes were similar for the two adhesive-bracket systems. GCF volumes and interleukin (IL)-1ss levels increased compared to baseline (p < 0.05). IL-17A levels and RANKL:OPG ratios were similar in both groups. in dental plaque, Aggregatibacter actinomycetemcomitans numbers were higher in the APC group at T-3. Fusobacterium nucleatum (Fn) counts statistically significantly decreased at T-1 and T-3 as compared to T-0 in the FF group (p < 0.05 and p < 0.01, respectively), whereas Fn counts increased in the APC group at T-3 (p < 0.01). Porphyromonas gingivalis, Streptococcus ores and total bacterial counts were significantly higher in the APC group than in the FF group at T-3 (p < 0.01). Conclusion: in orthodontic patients with good oral hygiene, the quantity of plaque on adhesive flash-free brackets and conventional brackets did not differ, but the constituents of plaque differed, with less pathogenic bacteria detected around adhesive flash-free brackets. Further studies also including a group of individuals with poor oral hygiene and longer follow-up periods may better clarify the issue.en_US
