Abstract
Using a toothbrush to clean the teeth for a pet dog is the best way to maintain the pet’s oral health. Meanwhile, the angle of a toothbrush neck can influence the posture and brushing strength of the pet caretaker, thereby affecting the cleaning efficiency. In order to compare the cleaning efficiency of pet dog toothbrushes with varied neck types, 20 volunteers with dog caring experience were selected. A medium-sized dog tooth model coated with water soluble pigment was provided to each volunteer, and then she/he was asked to brush the model for three minutes, using a specific type of pet dog toothbrush. Such process was repeated for each of 5 toothbrushes with varied neck types (all other elements remained the same), while different neck types were provided to each volunteer in random sequence. The pigment areas of the incisors, canines, and molars before and after tooth brushing were measured and calculated to speculate the cleaning efficiency of the toothbrush. At the end of the experiment, each subject was asked to evaluate five toothbrushes with respect to operating comfortability. The experimental results showed that the toothbrushes with backward tilting angle at the upper section of their brush necks performed significantly better than the other four groups of toothbrushes in cleaning molar and canine teeth, while the toothbrushes with backward tilting angle at the lower section, and with the upper section parallel to the brush handle were more comfortable in operation.

Food debris will form dental plaque in the oral cavity of pet dogs
Allan [2] have shown that to maintain the health of pet dog teeth, cleaning teeth with a toothbrush is the most effective way compared with prescription dentifrice-food and dentifrice chewing biscuits, because physical friction and swing of the toothbrush bristles with the tooth surface can avoid the generation of dental calculus
Volunteers were asked to perform the experiment by daily brushing their teeth for pet dogs, and five groups of toothbrushes were used for five trials, respectively, in a randomized order, with quantitative 20 ml of clear water to brush the teeth of this model for 3 minutes in each trial. (Figure 4) During tooth brushing, photographs and videos were taken to observe the changes in the operating posture and wrist angle of the subject
Summary
Food debris will form dental plaque in the oral cavity of pet dogs If it is not well cleaned, the dental plaque will begin to calcify and become dental calculus in 48 hours, which will lead to halitosis, but may even cause oral diseases, such as gingivitis and periodontal disease [1]. M. Allan [2] have shown that to maintain the health of pet dog teeth, cleaning teeth with a toothbrush is the most effective way compared with prescription dentifrice-food and dentifrice chewing biscuits, because physical friction and swing of the toothbrush bristles with the tooth surface can avoid the generation of dental calculus. According to the current research literature on toothbrushes, it is known that the bristles and brush necks are the main factors affecting the cleaning rate of teeth. Some scholars have conducted research on the angle design of toothbrushes [9] and found that the angle design of toothbrushes affects the way people brush their teeth, thereby affecting the cleaning rate of teeth
