Diagnostic value of full-mouth radiography in cats
ABSTRACT To determine the diagnostic value of full-mouth radiography in cats.
115 cats referred for dental treatment without a previous full-mouth radiographic series available.
In a prospective nested case-control analysis of multiple outcomes in a hospital cohort of cats referred for dental treatment, full-mouth radiography was done prior to oral examination and charting. After treatment, the clinical and radiographic findings were compared, with reference to presenting problems, main clinical findings, additional information obtained from radiography and unexpected radiographic findings. Importance of the radiographic findings in therapeutic decision making was assessed.
The main clinical findings were radiographically confirmed in all cats. Odontoclastic resorption lesions, missed on clinical examination, were diagnosed in 8.7% of cats. Analysis of selected presenting problems and main clinical findings yielded significantly increased odds ratios for a variety of other conditions, either expected or unexpected. Radiographs of teeth without clinical lesions yielded incidental or clinically important findings in 4.8 and 41.7% of cats, respectively, and were considered of no clinical value in 53.6%. Radiographs of teeth with clinical lesions merely confirmed the findings in 13.9% of cats, but yielded additional or clinically essential information in 53.9 and 32.2%, respectively.
The diagnostic yield of full-mouth radiography in new feline patients referred for dental treatment is high, and routine use of full-mouth radiography is justifiable.

ABSTRACT: Eleven dogs and four cats with buccodental alterations, treated in the Centro Veterinário do Gama, in Brasilia, DF, Brazil, were submitted to cone beam computed tomography. The exams were carried out in a i-CAT tomograph, using for image acquisition six centimeters height, 40 seconds time, 0.2 voxel, 120 kilovolts and 46.72 milliamperes per second. The ideal positioning of the animal for the exam was also determined in this study and it proved to be fundamental for successful examination, which required a simple and safe anesthetic protocol due to the relatively short period of time necessary to obtain the images. Several alterations and diseases were identified with accurate imaging, demonstrating that cone beam computed tomography is a safe, accessible and feasible imaging method which could be included in the small animal dentistry routine diagnosis.Pesquisa Veterinária Brasileira 01/2009; 29(8).

ABSTRACT: The intra oral radiography is the examination indicated for evaluation and diagnosis of dental disorders and other structures of the oral cavity. Another method that can be used is the cone beam computed tomography (CBCT), one viable alternative for diagnostic, allowing the identification of several oral disorders in domestic animals . The objective of this study was to compare the results of the examinations of CBCT and intra oral radiography as auxiliary method of diagnosis of the oral cavity. The study was used 25 animals, nineteen dogs and six cats, male and female, attended by the department of dentistry of the Centre of Veterinary Gama, in Brasilia, DF. The results showed that the CBCT is more faster to obtain the images and with superior quality than intra-oral radiography exam for the oral cavity diagnosis in dogs and cats.

ABSTRACT: Feline Odontoclastic Resorptive Lesions (FORL) is a painful disease that affects feline teeth and that is increasing in prevalence. The ethiology is still rather unknown. However, research on the ultra structure of the feline tooth may help us understand why FORL is so prevalent in cats and not in other species. Since the ethiology is still unknown, there is yet no profylaxis. The pathogenesis is rather well known; the hard structure of affected teeth gradually undergo odontoclastic resorption and resorptive lesions are often partly replaced with bone- or cementum-like tissue. FORL is classified into five stages where the tooth crown, in the last stage, is fractured off. Different therapies have been tried and used with more or less success. The most accepted treatment today is extraction of the whole tooth or crown amputation. A histopathological study of teeth from cats, diagnosed with FORL, is described in this work. Resorption of hard structure and repair with bone- or cementum-like tissue were frequently found, as well as inflammation of adjacent soft tissues in some cases. The findings in this investigation support observations made in earlier studies.
