“COMPARATIVE EVALUATION OF THE WETTABILITY OF THREE IRRIGATING SOLUTIONS USING CONTACT ANGLE.”

Abstract

Context: Aims: Estimating wettability of irrigating solutions. To evaluate and compare wettability of three irrigating solutions using contact angle. In this study three groups of irrigating solutions ie., Group A: 2.5% sodium hypochlorite Methods and Material: + 8.5% Etidronic acid or Hydroxy ethylidene disphosphonic acid (HEDP), Group B: 2.5% sodium hypochlorite + 8.5% ethylene glycol bis –N N N N' – tetraacetic acid (EGTA) and Group C: 2.5% sodium hypochlorite (NaOCl), with a sample size of 15 each were taken. A drop of each solution was placed on the glass slide using a micropipette. The photograph was made with an SLR camera, and the contact angle was measured using AutoCAD software. Statistical Analysis Used: Results: Chronbach's alpha coefcient and One-way ANOVA One-way ANOVA test revealed a signicant difference (p=0.001) among tested groups, i.e. between Group A & C, Group A & B. But there was no signicant difference between group C & B. Conclusions: Sodium hypochlorite in combination with HEDP showed better wettability comparatively than the other two irrigating solutions
