在牙科治疗中,医师、患者的眼睛可能受到损伤的原因很多。口腔内各种各样的微生物,例如葡萄球菌、链球菌、假单胞菌属等可能对眼睛致病。在治疗中,牙科涡轮机喷出的带有细菌的雾气可以从患者口腔飞溅到1.22米(4英尺)高的地方。在正常工作距离内,没有不带细菌飞沫的安全区,细菌甚至可以悬浮在空气中达30分钟之久.眼睛处于高浓度病原菌包围的危险中。有证据表明治疗前常规使用漱口药,可以减少雾气中细菌的浓度。潜在的眼睛损伤显然是由于治疗部位喷射出的微粒状物质引起的.这些物质可能来自口腔内(血液、唾液、牙石和牙齿的感染物)或牙科治疗器械和材料(钢制品、黄金或汞合金)。固体微粒可以射入并停留在结膜或角膜内,甚至穿入眼睛。这些微粒在口腔内已被污
In dental treatment, physicians, patients eyes may be damaged for many reasons. A variety of oral micro-organisms, such as Staphylococcus aureus, Streptococcus, Pseudomonas, etc. may cause eye disease. During treatment, the bacteria-laden fog ejected by the dental turbine can spatter from the patient's mouth to 1.22 meters (4 feet) high. Within normal working distances, there is no safe zone without bacterial droplets, and the bacteria can even be suspended in the air for up to 30 minutes. The eyes are at risk of being surrounded by high concentrations of pathogens. There is evidence that regular use of mouthwash before treatment can reduce the concentration of bacteria in the mist. Potential eye damage is apparently caused by particulate particulates ejected from the treatment site.These substances may come from within the mouth (blood, saliva, tartar and dental contaminants) or dental treatment devices and materials (steel products, gold or amalgam ). Solid particles can enter and remain in the conjunctiva or cornea, or even penetrate the eye. These particles have been stained in the mouth
