ABSTRACT

The objective of this study was to evaluate the affect of debonding on oral malodor. This study consists of three groups. The first group (debonding group) included 20 subjects with brackets and would be debonded in a month. The second group (bracket group) included 20 subjects who still undergone orthodontic treatment with brackets. The last group is a control group who did not receive orthodontic treatment. Oral malodor measurements, Gingival and Plaque Index scores were recorded in each group by same periodontist. Measurements were taken in first study groups before debonding (T1), 1 week after debonding (T2) and 4 weeks after bonding (T3). At the same time the measurements were applied to the second and control group. Data's were evaluated with three way ANOVA test. Bonferroni test were assessed when significant differences between the measurements were exist. Mann-Whitney U- test was used to compare both groups. Oral malodor, significantly decreased after debonding (P<0.05). One month after debonding the parameters were stable on debonding group and bracket group. (P>0.05). Control group did not show differences in all measurements. The comparison between groups showed significant differences between groups (P<0.05). Bonding brackets cause to increase on oral malodor. However, after debonding immediately oral malodor reached to the acceptable scores. Oral malodor could be another indicator to evaluate the oral health as Gingival and Plaque index scores.
