Abstract

Abstract: Objective: To study the application of polylactic acid (PLA) absorbable root canal post combined with cyanoacrylate adhesive in the restoration of infant anterior crown. Methods: A total of 100 infants with anterior residual crown admitted to our hospital from January 2017 to December 2018 were selected and randomly divided into control group and PLA group with 50 cases each. The control group was repaired with glass fiber short post combined with double curing resin adhesive, while the PLA group was repaired with PLA absorbable root pipe post combined with cyanoacrylate adhesive. The gingival condition, occlusal function, gingival sulcus inflammation, and clinical efficacy of two groups were evaluated, and the incidence of adverse events was followed up. Results: The gingival index and bite force after repair were higher than those before repair, and the gingival bleeding index was lower than that before repair. In addition, the gingival index and bite force of the PLA group were higher than those of the control group, and the gingival bleeding index was lower than that of the control group (P<0.05). After repair, the levels of TNF-α, CRP, IL-8, and IL-6 in the PLA group were all lower than those in the control group (P<0.05). The success rate of repair in PLA group was significantly higher than that in control group (P<0.05). The total incidence of adverse events in PLA group was significantly lower than that in the control group (P<0.05). Conclusion: PLA absorbable root canal post combined with cyanoacrylate adhesive can improve gingival state, inhibit the expression of TNF-α, CRP, IL-8, IL-6, and other inflammatory indexes in the treatment of residual crown of anterior teeth in infants, which has less stimulation to gingiva, reduces the occurrence of adverse events, and has a high success rate of restoration.

Key words: PLA absorbable root canal post, cyanoacrylate adhesive, restoration of residual crown of infant anterior teeth
