Abstract:

BACKGROUND: Resin has been widely used in the treatment of missing tooth tissue, but there are few reports

about the application of resin in the repair of posterior approximal caries.
OBJECTIVE: To investigate the therapeutic effect of resin ball filling on posterior approximal caries and its influence on periodontal health.
METHODS: A patient population scheduled for the restorative treatment of posterior approximal caries consisted of 100 patients, 57 males and 43 females, 18-60 years of age. All the patients were randomized into a study group receiving resin ball filling and a control group given traditional filling. Periodontal probing depth, periodontal probing bleeding index, plaque index, proximal contact tightness and food impaction were detected at 6 months after restoration, and then the success rate of filling repair was statistically calculated.

RESULTS AND CONCLUSION: (1) There was no significant difference in the success rate of filling between the study group and the control group (93.0% vs. 90.0%, P=0.447). (2) The clinical satisfaction rate of the study group was higher than that of the control group (94.0% vs. 46.0%, P < 0.001). (3) The rate of food impaction was lower in the study group than the control group (4.0% vs. 16.0%, P=0.024). (4) After 6 months of repair, the periodontal probing depth, periodontal probing bleeding index and plaque index of the two groups were significantly lowered (P < 0.05), but there was no significant difference between the two groups. In conclusion, compared with the traditional resin filling method, the resin ball filling for posterior approximal caries gets a better contact between the proximal surfaces, but no significant difference between the effects of the two filling methods on periodontal health.
