To achieve local anesthesia, dentists may need to administer a second injection. One widely used textbook advocates removing the needle before replacing the used cartridge. To determine the extent to which practicing dentists follow this recommendation, the author surveyed 144 practicing dentists in an upstate New York community and found that only 3 percent use this method. The rest leave the needle on to minimize their risk of a needlestick.
为了实现局部麻醉，牙医可能需要进行第二次注射。一本广泛使用的教科书主张在更换用过的药筒之前取下针头。为了确定执业牙医遵循这一建议的程度，作者对纽约州北部一个社区的144名执业牙医进行了调查，发现只有3%的人使用这种方法。其余的人则保留针头以尽量降低针刺风险。
