WebN2 - Aims and Objectives: This study was carried out to evaluate the effect of artificial aging on the marginal leakage of crowns and the credibility of three different luting cements in preventing marginal percolation. Materials and Methods: Thirty-six extracted intact premolars were selected for the study. WebThose least susceptible to caries attack in the permanent dentition are 1.Maxillary cuspids 2.Mandibular incisors 3.Mandibular premolars 4.Maxillary incisors 5.Maxillary 3rdmolars 2.Mandibular incisors 3. The principal bacterial agent involved in the caries process is 1.Lactobacillus acidophilus 2.Streptococcus sanguis 3.Streptococcus salivarius

WebJun 6, 2016 · The percolation rate is usually expressed in minutes per inch of drop. A rate of 60 minutes per inch (MPI), meaning the water dropped one inch in 60 minutes, is often the cutoff point for a standard gravity-flow … The percolation threshold is a mathematical concept in percolation theory that describes the formation of long-range connectivity in random systems. Below the threshold a giant connected component does not exist; while above it, there exists a giant component of the order of system size.
