The purpose of this in vitro study was to compare quantitatively the density of standard cold lateral gutta-percha compaction and warm vertical compaction by using the continuous wave of condensation technique. Forty transparent acrylic blocks with 30-degree, curved root canals were instrumented using Gates Glidden burs and Profile 0.06 taper rotary nickel-titanium files in a crown-down manner. The blocks were weighed and randomly assigned to two evenly distributed groups. Group A was obturated with the cold lateral-compaction technique using medium-fine, gutta-percha accessory points until the canal was completely filled. Group B was obturated with the continuous wave of condensation technique until the canal was completely filled. The blocks were weighed again after obturation. Data were analyzed using a two-sample t test at the 5% significance level. Results demonstrated that the continuous wave of condensation technique resulted in a significantly greater density compared with cold lateral compaction. Warm vertical compaction using the continuous wave of condensation technique in acrylic blocks resulted in a greater gutta-percha fill by weight compared with standard cold lateral compaction.

The goal of this in vitro study was to compare the effectiveness of three different placement techniques of calcium hydroxide paste in a curved canal. An acrylic resin block with a 44-degree curvature was instrumented to a #40 Flex-R file. The canal was filled with radiopaque calcium hydroxide paste using the following techniques: group 1, the paste was injected with an Ultradent tip; group 2, the paste was injected as in group 1 and followed by a size 35 Lentulo to working length; and group 3, the paste was placed with a size 35 Lentulo only, to working length. Each technique was performed 25 times. The radiodensity of the simulated canal was measured at 1, 3, 5, and 7 mm from the canal terminus. At 1 mm, the Lentulo was significantly better than the other two techniques. At 3 mm, the Lentulo technique and the combined technique were better than the Ultradent tip alone.

The guidelines recommended in the literature for the convergence angle of a crown preparation vary from 3 to 24 degrees. There is a lack of guidelines on techniques to achieve a specific axial inclination. The purpose of this article was to present a practical technique, with a diamond rotary cutting instrument of known axial inclination, to determine the diamond rotary cutting instrument angulations required to achieve the desired axial inclination of a preparation.
