Dental plaque associated with self-ligating brackets during the initial phase of orthodontic treatment: A 3-month preliminary study

Abstract

Background:To compare changes in the amount and distribution of dental plaque associated with placement of elastomeric modules over a self-ligating bracket during orthodontic treatment and to relate these changes to the periodontal inflammation.Materials and Methods:A cross-arch randomization trial was carried out at Bristol Dental School, United Kingdom. Clinical measurements of periodontal inflammation and plaque accumulation and microbiological test were done on 24 patients aged 11-14 years [Mean (SD) age = 12.6 (1.01) years] wearing fixed appliances (Damon 2 brackets, Ormco, Orange, CA, USA) at the start and 3 months into fixed orthodontic treatment.Results:In the first 3 months of treatment there was no statistically significant difference in bleeding on probing between incisors with and without elastomeric modules (P = 0.125 and 0.508, respectively). The difference in plaque accumulation was not statistically significant (P = 0.78). The difference in probing depths between the incisors was not statistically significant (P = 0.84). The microbiological analysis showed no difference.Conclusions:Based on this preliminary 3 months study, elastomeric modules were not significantly associated with any increased risk during treatment when compared to self-ligating brackets. The longer term studies are needed to further confirm the findings of the present study.

Changes in oral microbiota due to orthodontic appliances: a systematic review

“…In 37 of the 52 articles presented with moderate methodological quality [9–21,24–26,28,29,31–33,35–39,41–46,51–53,56,57], the major concern was the absence of repeatability tests. One article had a high quality [40] and the remaining 13 papers were classified as having a low quality [3,4,22,23,27,30,34,47–50,54,55].…”

“…Eigh studies analyzed self-ligating braces (SLB) [9,14,24,37–40,54]. Two studies [14,40] revealed no differences for BOP and PI between SLB and CB, while Nalçac et al and Uzuner et al [54] demonstrated a worsening in SLB.…”

Salivary microbial changes during the first 6 months of orthodontic treatment

“…The increased accumulation of dental plaque with the placement of orthodontic appliances induces the occurrence of dental diseases ( Lee et al, 2005 ; Van Gastel et al, 2008 ). Dental plaque is the primary etiological factor of white spot lesions, caries, gingivitis and periodontitis, which represent complications of orthodontic treatment and pose a great threat to oral health ( Al-Anezi, 2014 ). In some cases, severe periodontitis even causes the failure of orthodontic treatment.…”
