Basic Parameters

In machining with grinding, it is necessary to know values of geometrical parameters of cutting edges of abrasive grains. In this paper for modeling of cutting edges of abrasive grains with rotation surfaces based on generatrix as a power function and for division cutting edges on both plowing and forming a chip, values of basic parametersBP,NPwere obtained experimentally. The influence of abrasive grain size, sieve-shaking procedure, mechanical properties of workpiece and type of abrasive material on these parameters was determined. The restrictions of this model were designated. It is established that traditional parameters such as corner radiusrand apex angle 2θ can be used in case of microcutting with small grain penetration depth.

Endodontic Irrigation

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques.Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure the penetration depth of the irrigant. Three irrigation techniques were performed during this study: (i) passive irrigation, (ii) manually activated irrigation, and (iii) passive irrigation with an endodontic needle CANAL CLEAN®. Radiographs were performed to measure the length of irrigant penetration in each technique.Results. In comparison, passive irrigation with a conventional syringe showed infiltration of the irrigant by an average of0.682±0.105, whereas the manually activated irrigation technique indicated an average of0.876±0.066infiltration. Irrigation with an endodontic syringe showed an average infiltration of0.910±0.043. The results revealed highly significant difference between the three irrigation techniques (α=5%).Conclusion. Adding manual activation to the irrigant improved the result by 20%. This study indicates that passive irrigation with an endodontic needle has proved to be the most effective irrigation technique of the canal system.
