Pendant Drop Method

The purpose of this study was to evaluate the effect of an alcohol-based caries detector (Kurakay) on the surface tension of a conventional sodium hypochlorite (NaOCl) preparation, and a product containing a surface-active agent (Chlor-XTRA). The surface tensions of the following solutions were tested: NaOCl, a mixture of NaOCl and Kurakay 9:1 w/w, Chlor-XTRA, a mixture of Chlor-XTRA and Kurakay 9:1 w/w. Ten measurements per test solution were made at 20 C, using an optical method called the "Pendant drop method", with a commercially available apparatus. The addition of Kurakay reduced the surface tension for NaOCl (p<0.05) whilst no significant difference was detected for Chlor-XTRA (p>0.05). Statistically significant differences between the NaOCl and Chlor-XTRA groups were found (p<0.05). The addition of an alcohol-based caries detector resulted in a reduction of the original surface tension values for NaOCl only. Taking into account the fact that mixtures of NaOCl and Kurakay have been used to assess the penetration of root canal irrigants in vitro, the related changes in surface tension are a possible source of bias.

Dogs fed a regular diet were given intravenously 250 mg of Triton WR-1339 (a nonionic surface active agent) every 4th day. When sustained lipemia developed, their plasma free fatty acid (FFA) response to epinephrine and glusose was studied and compared with that of normal animals. The time course of the rise (epinephrine) or fall (glucose) of the plasma FFA was similar in the two groups of animals. The Triton-treated dogs had, however, plasma FFA levels twice as high as normals. Plasma FFA, which in control dogs were bound principally to albumin, were mostly associated in the Triton-treated animals with the low-density ß-lipoproteins. A partial shift of FFA from albumin to ß-lipoproteins could be produced in vitro by addition of Triton to normal canine serum.
