Intraoral fixed type of orthodontic appliance can cause reversible or irreversible
damages such as gingivitis, periodontitis, enamel decalcification, dental caries, root
resorption, and pulpal changes. Such an increase causes gingival inflammation and
enamel decalcification.
The purpose of this study is to get knowledge on initial changes in dental plaque,
gingvitis, and enamel decalcification after bonding fixed orthodontic appliances according
to time flow, gender, and sides(right/left) of premolar region.
For control group, 48 students of dental college, Yonsei university(26 males, 22
females) were chosen: for experimental group, 73 orthodontic patients(36 males, 37
females) who will be treated with fixed appliances were chosen, All the subjects had no
systemic disease, juvenile periodontitis and all the females had passed their menarche.
Tooth brushing instruction was given to all the subjects prior to the experiment, For
control group, plaque index, gingival index, and decalcification index were measured
twice at 3 weeks interval : for experimental group, the same was done prior to, 3, 6, 9
weeks after bonding fixed appliances.
The following results were obtained :
1. In plaque index 3 weeks after placement of appliances, and it showed gradual
increase afterwards.
2. In gingival index 3 weeks after placement of appliances, and afterwards it showed
increase at a faster rate than plaque index.
3. Enamel decalcification began to show between 3 and 6 weeks after bonding fixed
appliances. Decalcification index began to increase 6 weeks after appliance placement,
but there was no statistical significance.
4. When the comparison was made between two sides of premolar region, the right side
showed greater index in plaque and gingival index of experimental group.
