| Objective:To explore the prevention effect of gingival retraction cord on the inflammation and overhang of patients
with wedge-shaped defects.Methods:100 cases with wedge-shaped defects who were treated in our hospital were selected and according
to the different treatment methods, the patients were divided into the study group and the control group. The patients in the study group
were treated with gingival retraction cord combined with filling composite resin for dental wedge-shaped defects, while the patients in the
control group were treated with conventional method combined with filling composite resin. Then the effects of filling body and the incidence
of suspension were observed and compared, and the changes of AST were detected before and after the treatment.Results:After
treatment, the levels of AST in the two groups were higher than before treatment, and the study group was lower than that of the control
group, and the difference was statistically significant (P<0.05). The incidence of filling body and the edge in the study group was lower
than that of the control group, and the difference was statistically significant (P<0.05). The patients were followed up for 1 year, and the
incidence of overhang in the study group was lower than that of the control group, and the difference was statistically significant (P<0.
05).Conclusion:Gingival retraction technology has better effects on the treatment of dental wedge-shape defects, which can effectively
reduce the inflammatory in periodontal tissue and the incidence of overhang, and it has certain extend value in clinical. |
