WebThen the specimens were subjected to final irrigation with 5.25% NaOCl. Following de-coronation and splitting of roots, one-half of each root was examined under scanning electron microscope (SEM) at 1000X and 2000X magnification for smear layer at coronal, middle, and apical thirds. WebBetween 1997 and 1999, the prevalence of Demodex canis mites was determined in 150 dogs. In two dogs, we found two different species of mites; Demodex canis and another, unidentified, Demodex mite. The unidentified Demodex mite species had several different morphological features. First, it had a short opisthosoma and an obtuse end.
