ABSTRACT

Objective: To compare the side effects of the molar bands and buccal tubes on periodontal health during orthodontic treatment. Methods: We selected 42 patients who treated with the fixed appliance, they all in the age range of 12-16 years, for each one choosing two first molars and one of the second molars in mandible as research objects, it is a total of 126 teeth. We bonded both a buccal tube and a molar band in the first molars of mandible, using the stochastic method to decide which side bonded the buccal tube, bonding it in the middle of the tooth crown. Take the second molar in buccal tube side as a blank control. In this study, 84 first molars were selected as the experimental group and 42 second molars without fixed appliance as the control group. The experimental group can be divided into two small groups. Buccal group, the 42 molars which used the buccal tubes in orthodontic treatment. Moral group, the 42 teeth which used the molar bands in orthodontic treatment. Furthermore. Gingival index and Pocket probing depth were recorded for clinical evaluation, IL-1 and IL-6 were tested use ELISA in this study. Results: In this study, there was no difference in all of the indexes among three groups before our experiment. After placing fixed appliance 6 months and 12 months, both of the experimental groups (buccal tube group and molar band group) showed that GI, PPD continued to increase. Compared with baseline, they had significant difference (P < 0.05), although there was no significant difference between buccal tube group and molar band group (P>0.05), the mean value of the GI, PPD in molar band group was larger than buccal tube group. After placing fixed appliance 6 months and 12 months, both of the experimental groups showed that IL-1 and IL-6 continued to increase. Compared with baseline, they had a significant difference (P < 0.05). In addition, there was a significant difference between IL-1 and IL-6 between buccal tube group and molar band group (P<0.01). It showed that inflammatory substances in the gingiva groove liquid increased during the treatment. Conclusion: In orthodontic treatment, buccal tubes caused less inflammatory response on periodontal health than molar bands, which was helpful to achieve better treatment effect. We concluded that buccal tube was more conducive to the periodontal health than molar band.
