　　病人：我的牙痛得很厲害。

　　醫(yī)生：哪個牙痛？

　　病人：下邊最后一顆牙遇冷熱食物時疼。近三天來疼痛加重，不能分辨是哪個牙痛。

　　醫(yī)生：晚上疼痛加重嗎？

　　病人：是的，夜間疼香港無法入睡。

　　醫(yī)生：請張開嘴，讓我給您檢查一下，啊！下邊最后一個磨牙爛了，洞很大，已經(jīng)引起了牙髓炎，所以疼痛劇烈。

　　病人：如何治療呢？

　　醫(yī)生：我先給您打一針麻藥，然后用電鉆鉆個眼兒，放點(diǎn)止疼藥水在里面，很快就不疼了。

　　……

　　病人：大夫，現(xiàn)在牙已經(jīng)不痛了。

　　醫(yī)生：我給您一些止痛藥，需要也吃一片。兩天之后再來復(fù)診。再見。

　　病人：謝謝您，大夫。再見。
