Abstract:
Objective:To compare the suction effect of modified and conventional strong suction devices on sand blasting dust during sand blasting cleaning.Methods:A pre-experiment was carried out using an oral bionic head mold containing 28 standard teeth to compare the dust suction effect of the modified and conventional strong suction devices under different conditions. Using the convenient sampling method, a total of 186 patients who underwent sandblasting treatment in Department of Periodontology in Hospital of Stomatology of Jilin University were selected from February to April 2019, and they were divided into the experimental group and the control group. The experimental group used a modified strong suction device, while the control group used a clinical routine strong suction device. The comfort and VAS scores of patients in the two groups during the sandblasting treatment were compared.Results:Under the conditions of 1/3 and 2/3 of the amount of blasting, 5 and 10 minutes of blasting time and 15 cm and 30 cm of sandblasting powder collection distance, the dust reduction effect of the experimental group was better than that of the control group, and the differences were statistically significant ( P<0.05) . The comfort score of the experimental group was higher than that of the control group and the VAS score of the experimental group was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The modified strong suction device can control the spread of dust from pollution sources and improve the consulting room environment, thereby reducing the occupational hazards of medical staff, reducing the stimulating inducement of people with low immunity and improving the comfort of patients and the quality of nursing.
