Periodontal health in patients under conventional and lingual orthodontic therapies

Abstract

ObjectiveSome clinical periodontal health parameters were assessed comparatively in patients using conventional and lingual brackets.Material and methodA trained examiner registered the frequencies of visible plaque (VP), bleeding on probing (BOP), as well as the simplified oral hygiene (OHI-S) and modified gingival (MGI) indices in 83 subjects from two clinics. The effects of orthodontic treatments on periodontal health were analyzed using logistic regression (α = 0.05).ResultIn the conventional group, the frequency of visible plaque was significantly higher on the buccal surfaces of anterior (OR = 12.5) and maxillary posterior (OR = 3.6) teeth, p < 0.01. BOP in posterior teeth was also more frequent in this group, p < 0.05. The lingual group presented higher frequency of visible plaque on the lingual surfaces of anterior teeth (OR = 4.3; p = 0.0034). The conventional group had significantly higher frequencies of mild gingivitis in the buccal regions of anterior (OR = 9.0) and maxillary posterior (OR = 16.7) teeth, p < 0.05, and anterior papillae (OR = 9.0; p = 0.0003). On the other hand, the lingual group evidenced mild gingivitis more often in the lingual regions of anterior teeth (OR = 54.5), p < 0.01.ConclusionBased on the results of this study, the clinical periodontal health conditions may be considered acceptable for patients using both conventional and lingual brackets.

Lingual Orthodontic Treatment: Efficacy and Complications

“…54 Also, it has been shown that patients with a labial appliance experience significantly higher frequency of gingivitis in posterior maxillary teeth, but patients with lingual appliances experience it more often in lingual anterior teeth. 55 Regarding the bleeding on probing (BOP) and PD, some studies have shown the significant increase of PD and BOP, 56-58 and the others have stated no significant differences. 56,58-61 Therefore, further studies are required to prove the effects of lingual appliances on these parameters.…”

The Impact of Lingual Orthodontics on Gingival and Periodontal Health; A Systematic Review of Controlled Clinical Trial Studies.

“…However, it was seen that these parameters were primarily adjusted three months after the removal of brackets. Although lingual therapy is considered the most visually appealing orthodontic treatment due to the absence of visible brackets and the absence of protruding lips, there have been multiple reports of discomfort, changes in speech, and difficulties in maintaining proper oral hygiene [15,16] .…”
