Brief Summary

Periodontal diseases are a prevalent issue, often leading to gingival recession, where the gingival margin recedes, exposing the tooth root and causing various problems. Gingival recession can be managed through both non-surgical and surgical interventions The non-surgical approach often involves plaque control and addressing any underlying inflammatory conditions. However, in cases of advanced recession, surgical treatment may be necessary Several treatment techniques have been proposed, which can be divided into pedicle and free grafts. The latter can also be classified as free gingival grafts (FGG) or as connective tissue grafts (CTG). Other treatment options include soft tissue substitutes or regenerative therapies Harvesting graft from the palate has several problems, such as pain, inflammation, bleeding, flap necrosis, and infection at the donor site. For this reason, we need a substitute for soft tissue graft harvesting Carbopol polymers, also known as carbomers, are widely utilized in pharmaceutical formulations for their excellent mucoadhesive properties. This high molecular weight, cross-linked acrylic acid polymers are particularly effective in enhancing the adhesion of formulations to mucosal surfaces, thereby improving drug delivery and bioavailability

Detailed Description

Gingival recession is a common finding in daily clinical practice. Several issues may be associated with the apical shift of the gingival margin such as dentine hypersensitivity, root caries, non-carious cervical lesions (NCCLs), and compromised aesthetics. The first step in an effective management and prevention program is to identify susceptibility factors and modifiable conditions associated with gingival recession. Non-surgical treatment options for gingival recession defects include establishing optimal plaque control, removing overhanging subgingival restorations, behavior change interventions, and using desensitizing agents. In cases where a surgical approach is indicated, coronally advanced flap and tunneling procedures combined with a connective tissue graft are considered the most predictable treatment options for single and multiple recession defects. If there is a contraindication for harvesting a connective tissue graft from the palate or the patient wants to avoid a donor site surgery, adjunctive use of acellular dermal matrices, collagen matrices, and/or enamel matrix derivatives can be a valuable treatment alternative. For gingival recession defects associated with NCCLs a combined restorative-surgical approach can provide favourable clinical outcomes. If a patient refuses a surgical intervention or there are other contraindications for an invasive approach, gingival conditions should be maintained with preventive measures. This paper gives a concise review of when and how to treat gingival recession defects.
