Analysis of common reaction after operation of live medullary discoloration tooth whitening

Abstract

Objective To analyze the common adverse reactions of live medullary tooth bleaching after operation and its effect on whitening effect, and to provide basis for future treatment. Methods Ninety patients with live medullary tooth discoloration admitted from January 2017 to December 2017 in Stomatology Department of General Hospital of Yima Coal Industry Group were selected as the objects of observation. All patients were treated with Beyond cold light whitening, and all patients were divided into group A (light 12 min), group B (light 10 min) and group C (light 30 min), according to the length of illumination, with 30 cases in each group. The postoperative reactions were recorded, and the whitening effects were compared. Results The common adverse reactions of the three groups after operation were tooth sensitivity and pulp stimulation, and there was no significant difference in the incidence of postoperative reaction between the three groups (P>0.05); the dental sensitivity duration was (73.46±6.13) d, the pulp stimulation disappeared within 3 d after surgery, without gum discomfort. The total effective rate was 100% in group A, an 93.33% in group B, and 83.33% in group C, the total effective rates in group A and group B were higher than that in group C (P<0.05). Conclusions The common reaction of patients with vital pulp discolored teeth after Beyond cold light treatment is tooth sensitivity and pulp stimulation, but they will not affect the whitening effect. In the treatment, the light duration can be increased appropriately to improve the whitening effect. Key words: Vital pulp discolored teeth; Whitening; Postoperative reaction
