Abstract

Background: When the finish line is at or inside the gingival sulcus,gingival displacement is necessary to produce precise imprints for the creation of fixed prosthesis. For the sake of tissue management effectiveness and dimensional accuracy, a comparative study of these novel gingival displacement materials was judged essential. Materials and Methods: A total of five different gingival retraction agents namely Stay put gingival retraction cord, 15% Aluminium chloride, 0.05% Oxymetazoline hydrochloride, 0.05% Tetrahydrozoline hydrochloride and 20% Ferric sulphate were used in this study. A total of 20 participants were used in this study on which all these five gingival retraction materials were used at a regular interval of seven days on right mandibular first molar. The pre retraction and post retraction impression were taken using addition silicone and poured using die stone. The sectioned die stone models were studied under stereomicroscope to measure the amount of gingival retraction in horizontal direction. Result: Preliminary findings indicate that 0.05% Oxymetazoline hydrochloride demonstrated superior efficacy in achieving Mean Displacement 14.9 (μm) gingival retraction compared to traditional methods Mean Displacement 4.9 (μm) in 15% aluminium chloride group.New retraction methods namely 0.05% Oxymetazoline HCL(Nasivion) and 0.05% Tetrahydrozoline HCL (Visine) have better horizontal displacement in comparison to the traditional retraction methods. Conclusion:0.05% Oxymetazoline HCL found to be superior on 0.05% Tetrahydrozoline HCL Retraction method including the traditional methods.
