This in vitro investigation studied the effect of storing dental local anesthetic cartridges at room temperature and at 37 degrees C on the forces required for cartridge failure under strong injection pressures. Storage for three hours at the higher temperature resulted in a significant reduction in the forces required to produce failure of plastic cartridges (leakage of solution around the bung). The forces needed to cause failure of glass cartridges did not differ between the two temperatures.
这项体外研究探讨了在室温及37摄氏度下储存牙科局部麻醉剂药筒，对在强注射压力下药筒破裂所需力量的影响。在较高温度下储存三小时，导致塑料药筒破裂（溶液在塞子周围泄漏）所需的力量显著降低。两种温度下玻璃药筒破裂所需的力量没有差异。
