Abstract

Objectives: To studygingivitis statusand some related factors in patients wearing orthodontic braces. Subjects and research methods: The study was conducted on 62 patients wearing braces with gingivitis requiring treatment. All patients were clinically examined for gingival index (GI) and plaque index (PLI). The result was analized by medical statistic software. Results: There was no significant difference in the mean value of indicators by gender and time of wearing braces. The GIindex of under 18 year -old group was higher than that of over 18 year-old group. The group of previous calculus removal over 12 months  had GI index higher than group having calculus removed during 6-12 months before the study (p<0,05). The GI and PLI indexes were highest in the group brushing teeth once a day, lower in the group brushing twice a day, and lowest in the group brushing three times a day. These indexes of the group that did not have the habit of using supportive measures teeth cleaning was significantly higher than the group using at least 1 dental cleaning support (p<0,05). Conclusion: There is no difference of gingival status between men and women. The gingivitis level of under 18 year -old group wasmore severe than that of over 18 year-old group. The gingivitis status was related to the brushing times a day, the habit of using teeth cleaning support, the nearest time of calculus removal but not related to the time of wearing braces.
