Periodontal-Restorative Interface in Composite Resin: Case Report on the Integration between Periodontics and Dentistry

Case Report on the Integration between Periodontics and Dentistry

Abstract

Introduction: The interrelationship between the areas of Periodontics and Dentistry goes beyond aesthetics, requiring health and functionality. During restorative procedures, there must also be a concern with maintaining gingival health and red aesthetics. In cases of extensive carious lesions reaching the supracrestal periodontal tissues, more invasive treatments should be chosen, such as clinical crown lengthening surgery or intraoperative restorations, requiring the creation of a gingival flap for better visualization of the carious lesion and an open-field restorative procedure. Objective: To report the clinical case of a restorative procedure for a class II subgingival carious lesion, with the creation of a gingival flap for the preservation of periodontal tissues. Methodology: This is a clinical case carried out in 2024 at the Faceg Dental Clinic. The intervention consisted of creating a gingival flap, removing subgingival carious tissue, applying layered composite resin, and applying appropriate finishing to preserve periodontal health. Results and Discussion: The supracrestal space refers to the anatomical distance between the junctional epithelium and the alveolar bone crest. This space is composed of two main structures: the junctional epithelium and the supracrestal connective tissue. Flowable resin, or fluid composite resin, is a restorative material widely used in dentistry, characterized by its low viscosity and excellent flow. Its formulation is similar to that of conventional composite resins, but with a lower inorganic load, which provides greater fluidity and ease of adaptation to cavities and dental surfaces. The results observed after six months of follow-up showed satisfactory tissue healing and the absence of periodontal changes. Technical knowledge associated with the appropriate choice of materials can prevent failures and promote better clinical results. During the procedure, periodontal biological principles were respected, including preservation of the supracrestal space, use of appropriate materials and correct execution of the clinical steps. Conclusion: The case presented reinforces that the integration between Periodontics and Dentistry is fundamental for restorative success, especially in cases involving the supracrestal periodontal spaces. The clinical stability observed demonstrates the importance of interdisciplinary planning and the use of techniques that respect periodontal limits.
