Abstract:

BACKGROUND: In the comprehensive treatment of cracked teeth, the temporary protection using the orthodontic band and resin temporary crown can effectively prevent tooth fracture and protect the cracked teeth with a higher clinical success rate.
OBJECTIVE: To evaluate the differences in clinical efficacy of orthodontic band and resin temporary crown on the temporary protection of cracked teeth.
METHODS: Totally 189 patients (97 males and 92 females, aged 19-65 years) with cracked teeth were selected, randomly divided into two groups and respectively underwent the temporary protection to cracked teeth with the orthodontic band (n=93) and resin temporary crown (n=96) in the comprehensive treatment. Retention effect, periodontal status and patient satisfaction were observed.
RESULTS AND CONCLUSION: There were three cases with loose band and one case with falling band in the group of orthodontic band; there were two cases with falling band in the group of resin temporary crown. No significant difference between two groups in the retention effect was found. There were 11 cases of gingivitis or exploring hemorrhage in the group of orthodontic band and 2 cases in the group of resin temporary crown, indicating the periodontal status in the group of resin temporary crown was better than that in the group of orthodontic band (P < 0.05). There were 18 cases of lower satisfaction for poor color, expand feeling caused by the rubber band and discomfort caused by the band protruding from tooth surface in the group of orthodontic  band; there were 3 cases of lower satisfaction in the group of resin temporary crown, and the patient satisfaction in the group of resin temporary crown were higher than that in the group of orthodontic band (P < 0.05). There is a better clinical effect in the temporary protection to cracked teeth by using the resin temporary crown, especially in the terms of  retention effect, periodontal status and patient satisfaction.
