Orthodontic brackets contribute to the accumulation of bacterialplaque on tooth surfaces because they hinder oral hygiene.In contrast to conventional brackets, self-ligating brackets donot require additional parts to support the arches, thus improvingdental hygiene. The aim of this study was to compare thegingival response in orthodontic patients wearing self-ligatingor conventional brackets. A sample of 22 patients aged 16 to 30years was divided into two groups Group A, treated with selfligatingbrackets (Damon system) and Group B, treated withconventional brackets (Roth technique). The following wereassessed during the treatment Plaque Index (PI), GingivalIndex (GI) and Probing Depth (PD), and sub-gingival sampleswere taken from teeth 14/24 for microbiological observation.No statistically significant difference was found between GroupsA and B; p>0.05 (sign-ranked) or between PI, GI and PD at thedifferent times (Friedmans Analysis of Variance), even thoughthe indices were found to increase at 14 days, particularly forself-ligating brackets. The quantity and quality of microorganismspresent were compatible with health on days 0, 28 and 56.As from day 14 there is a predominance of microbiota compatiblewith gingivitis in both groups. In the samples studied,orthodontic treatment increases bacterial plaque and inflammatorygingival response, but gingival-periodontal health canbe maintained with adequate basic therapy...
