Objective: To explore the application of the gingival line technique in filling treatment for elderly patients with wedge-shaped tooth defects, evaluate its role in aesthetic restoration, and compare it with the conventional gingival exposure method.
Methods: A total of 60 elderly patients with subgingival wedge-shaped defects were enrolled between March 2023 and March 2024. Using a randomized block design, the participants were divided into two groups (Observation Group: 30 cases; Control Group: 30 cases). The Observation Group received margin line technique-assisted filling restorations, while the Control Group received conventional resin fillings. Comparative analyses were conducted on color difference scores, fit scores, gingival inflammation and bleeding incidence rates, aesthetic evaluations, and patient satisfaction levels between the groups. Clinical examinations and radiographic assessments were used to evaluate color difference and fit scores, while gingival health scores were employed to assess gingival inflammation and bleeding incidence ra
Results: After treatment, the observation group showed significantly lower color difference and marginal fit scores than the control group (P<0.05). The incidence of gingival inflammation and bleeding was significantly lower in the observation group than in the control group (P<0.05). In terms of aesthetic scores, the observation group had higher scores in color, shape, function, and overall satisfaction compared to the control group (P<0.05).
Conclusion: The gingival line technique has a significant aesthetic effect in the restoration of elderly wedge-shaped tooth defects. It can effectively improve the adaptation between the restoration and the gingiva, reduce gingival inflammation and bleeding, and enhance the aesthetic effect and patient satisfaction after restoration, making it worth promoting.
