HALITOSIS WITH FIXED ORTHODONTIC APPLIANCE VS REMOVABLE ORTHODONTIC ALIGNERS: A PILOT STUDY
areas 11, 14. Alternatively, Schaefer et al. showed that removable orthodontic appliances, particularly invisible aligners, allow a more adequate oral hygiene 16. About the correlation between halitosis and orthodontic aligners treatment it is shown that this kind of treatment did not lead to an increase of plaque and bacterial count, thus neither halitosis, nor oral dryness, nor high plaque or gingival index measurements were observed.
5. Conclusion The study shows similar results in both groups, but the aligners group shows better results because none of the subjects have high level of volatile sulfur compounds or, better yet, they are all below the threshold for the three values considered. In the second group, instead, there are some differences among the patients because of their different level of oral hygiene, which can cause important changes in the VSC analysis. The presence of brackets, ligatures and archwires is a big increasing factor for halitosis. Indeed, they cannot be removed by the subject during oral hygiene procedures therefore plaque retention is surely higher than in the aligners group, where the appliance can be removed and oral hygiene can be performed as any subject without orthodontic appliances would do 17. This study is only a pilot study and should be expanded in order to produce more consistent results, but we can already assert that the possibility to remove the oral device certainly provides a better outcome for oral hygiene procedures and, consequently, improves the halitosis condition. In conclusion we can consider oral hygiene and halitosis as important factors in order to decide what kind of orthodontic device is better suited for the single patient.
