Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Gingival recession is characterized by the exposure of root surfaces of the tooth, is attributed to the apical migration of the gingival marginal tissue, and it is a frequently noted clinical feature in all populations. Other than cosmetic problems, a gingival recession can have a causative role in tooth sensitivity, and contribute to difficulties in oral hygiene maintenance or root caries. Moreover, it may worsen with time.
The ultimate goal of surgical root-coverage procedures (Periodontal plastic surgery) is the elimination of the recession defect with minimal probing depths after treatment, along with the ability to restore the natural color and texture of the gingiva (gum). By achieving root coverage, overall improved aesthetics, prevention of non-carious cervical lesions or root caries, and treatment of the resulting root sensitivity should be expected.
Surgical interventions in general, and in particular those aiming to reconstruct tissues lost due to trauma or disease in particular, are biologically dependent on a cascade of unimpaired wound healing mechanisms, including a non-disrupted inflammatory process, vascularization(blood supply) of the wound area, and consequent tissue regeneration. Wound healing has been defined as "the natural response to injury compiling a cascade of complex events orchestrated in a way that many cell types guided by the release of soluble mediators and signals. In a bid to enhance this phase, autologous platelet 'concentrates' were developed, derived from centrifuged blood of patients and applied as surgical adjuncts. Previous studies indicate that leucocyte plasma rich fibrin (LPRF/newest generation of platelet concentrates) preparations significantly modulate wound healing and promote tissue regeneration in a variety of oral surgical procedures. Clinical studies where LPRF is analyzed at the molecular level to quantify the temporal release of growth factors, cytokines, or other biomolecular components are still lacking. Despite the broad application of LPRF in modern dentistry information which integrates clinical and molecular data from in vivo models are essential to elucidate its relevant biological mechanisms. The mechanisms of action are unclear, and the relative role of their different components have not been fully explained. This study will aim to investigate if LPRF can offer superior clinical outcomes and will compare the concentrations and kinetics of wound healing regulators in root coverage procedures with and without local application of LPRF.
