Abstract

The present in vitro study was conducted with the aim of evaluating and comparing the contact angles of calcium hydroxide to the radicular dentine using different aqueous and non-aqueous vehicles. Sixty dentine disks of 2mm thickness were divided into two groups and three sub-groups of ten specimens each. In group 1 aqueous vehicles and group 2 non-aqueous vehicles were used. The calcium hydroxide powder was mixed with various vehicles in the ratio 2:1 by weight. Controlled volume (0.1ml) droplets of intracanal medicaments were placed on to dentine disks and contact angle was measured by Dynamic contact angle analyzer. One-way ANOVA and Post hoc test were used to analyze the result statistically. Present study concluded that aqueous vehicles produced lower contact angles (distilled water < chlorhexidine < anesthetic solution) with no statistical significance among the experimental groups, compared to non-aqueous vehicles (glycerin < propylene glycol < iodoform) with iodoform showing statistical significance with other non-aqueous experimental vehicles.
