comparing high speed dental turbine and endoscopic device in crack formation following cavity preparation in periapical surgeries in cat teeth

in present research study, 44 canine teeth of with completely formed apex was selected in 11 cats. jaw bones were removed while teeth were kept intra alveolar sockets and routine root canal therapy was performed on each root. afterwards, 3mm of each root were cut apically. 20 teeth underwent cavity preparation via high speed dental turbine and round diamond bur, 20 via endosonic device and 4 (10% of all) remained untreated as control group. then, the cavity walls were assessed with stereomicroscope while the teeth were still kept in their alveolar sockets in order to detect cracks.
