Abstract:
Objective To introduce a kind of baffle measuring spoon which could measure the exact amount of alginate impression material powder and evaluated the effect of its application in the alginate impression materials. Methods A total of 10 nurses were randomly selected in our hospital, they were asked to take 1/2 and 1/3 spoonful of powder, according to their own experience and by using the baffle measuring spoons. The accuracy was weighed and analyzed, and the mixing effect were evaluated by the same doctor. Results When taking 1/2 spoonful of powder, there was no significant difference in movable baffle measuring spoon, fixed baffle measuring spoon and control group (P >0. 05). There were significant difference in movable baffle measuring spoon and control group (P<0. 05). When taking 1/2 spoonful of powder, there was no significant difference in fixed baffle measuring spoon and control group (P>0. 05). There were significant difference in movable baffle measuring spoon and fixed baffle measuring spoon, control group (P<0. 05). The qualified rate of baffle measuring spoon was 95. 0%, which was significantly higher than 80. 0% of hand-testing (χ2 =4. 114, P<0. 05 ) . Conclusions Application of baffle measuring spoon in alginate impression material cannot only improve the accuracy, efficiency, but can ensure the mixing quality of the alginate impression material.
