EVALUATION OF SURFACE TENSION OF THREE ROOT CANAL SEALERS USING PENDANT DROP METHOD

Dr. Vinodha. C, Dr. Indira. R

Abstract :

The aim of this study was to evaluate the surface tension values of established and potential endodontic sealers.Densities of zinc oxide eugenol ,AH Plus and Bioceramic sealers were calculated using pendant drop method.Surface tension was evaluated using rame hart goniometer with DROP image analyser software[Finn Knut Hansen1990–2006].The results show that surface tension of zinc oxide eugenol was the least followed by AH plus and Bioceramic sealer.Bioceramic sealer showed the highest surface tension of 47.8 Nm.From other studies it is known that bioceramic sealer has the highest dentinal tubular penetration.Various factors like dentin roughness,wetness,type of irrigant used,viscosity ,hydrophilicity of root canal sealers,temperature,dentinal tubule texture and density etc influence the penetration of sealers.Further studies are needed to evaluate the role of surface tension of root canal sealers as a potent influencer in dentinal tubule penetration for enodontic success.
