Lab 5: Preparation of Synthetic Banana Oil September 20th‚ 2012 Purpose: The main purpose of this experiment was to synthesize banana oil (isopentyl acetate.) Ester are often prepared by the Fischer esterification method‚ which involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst. Theory: Synthesize isopentyl acetate by combining isopentyl alcohol with acetic acid and sulfuric acid and then heating the reaction mixture under reflux for an hour. The alcohol

Objective: The objective of this study was to investigate the effect of Morinda citrifolia on the microhardness of root dentin‚ when used both as a root canal irrigant and as an intracanal medicament. Method: 40 extracted teeth were cleaned and shaped. A 3 mm section of each root was taken at the middle-third level and embedded in cold cure acrylic resin. Vicker’s Hardness Test was used to measure the microhardness of each specimen prior to exposure with the respective irrigants and Root anal Mediaments
