Radiografia intraoral e convencional da hemiarcada superior direita de gatos domésticos

Abstract

The aim of this research was to evaluate the right maxilla hemiarcade of cats through parallel dental radiographic techniques, applying Han Shin intraoral film positioner. Images obtained with this method were correlated with conventional radiographic techniques (extraoral). The goal was to establish the advantages and disadvantages to detect possible dental and periodontal diseases. Thirty mixed breed cats were evaluated, 17 males and 13 females, ages one to three years old, confined in catteries in the Department of Zootecnia of the Federal University of Lavras/MG. Radiographies of the right maxilla were taken with the animals under general anesthesia, and three incisors, one canine, three premolars and one molar teeth were included in the intraoral and extraoral images. The radiographic images were analyzed and a qualitative comparison of pairs of intraoral and conventional images from the same animals was achieved. To establish the dental image procedures that were better adapted for cats, the McNemar Test (Modified Qui-Square) was used for statistical analysis. The intraoral technique was superior than the extra oral (P≤0,05), for findings relating to increased periodontal space, broad root canal and rounded apex, and also for a more detailed evaluation of canine, premolar and molar teeth in cats.
