Periodontal disease is caused by dental plaque accumulation on teeth and adjacent structures. Indices have been formulated for its measurement considering the amount and intensity of dental plaque (DP) and dental calculus (C) on the surface of teeth through subjective visual evaluation. This study aims at assessing the computerized analysis method for measurement of DP and C areas on the teeth of dogs by comparing it with the visual evaluation in the oral cavity. Ten beagle dogs with similar characteristics and kept under the same management and diet were used. Evaluations of oral cavity occurred before surgical prophylaxis (performed under general inhalation anesthesia) and after seven days for DP and 28 days for C. The computerized C area evaluation showed to be statistically better than the visual evaluation before and after prophylaxis. It was concluded that the computerized evaluation is beneficial when compared to visual evaluation, providing greater precision in the area measurement. |
