　　What About Plain Old Bad Breath?

　　About 25% of adults world-wide suffer from chronic halitosis that has nothing to do with serious illness. Below, some bad-breath basics:

　　It starts in the mouth. Most of the time, halitosis is caused by bacteria buildup岸often on the back of the tongue, where postnasal drip collects, according to Mel Rosenberg, a professor of human microbiology at Tel Aviv University and co-founder of the International Society for Breath Odor Research.

　　Bacteria also thrive between teeth and gums, where they produce sulfides and other malodorous compounds, including putrescine, found in decaying meat, and isovaleric acid, which smells like sweaty feet.

　　Some cases actually stem from the nose, as a result of blocked sinuses. If a child suddenly develops an offensive odor, Dr. Rosenberg says, check for a bead or other foreign body in the nose.

　　But it might be in your head. About a quarter of the people who seek help from dentists or clinics for bad breath suffer from halitophobia, the fear of bad breath, instead. 'They have parents or children or friends who have bad breath, which makes them think they do, too,' says Dr. Rosenberg. Having a bad taste in the mouth doesn't mean you have bad breath.

　　The best way to know isn't licking your wrist or blowing into your hand or under a blanket. Some dentists have 'halimeters' that can measure sulfur compounds in breath. An easier way: Ask a trusted friend or family member.

　　The best way to vanquish it involves regular brushing and flossing, of course, as well as cleaning the back of your tongue with a tongue scraper. (Breath sprays and mints generally only mask the problem temporarily.) Gargling with mouthwash can help, but those containing alcohol can dry your mouth and make the problem worse.

　　Drinking plenty of water and eating breakfast regularly岸preferably with rough foods like whole-wheat toast岸can help mobilize bacteria that accumulate overnight, Dr. Rosenberg says. 'Just by having breakfast, you can reduce the volatile sulfur by at least 70%.'

　　關于口臭，你知道多少?

　　全世界約有25%的成年人患有并不代表體內(nèi)存在嚴重疾病的慢性口臭。以下是關于口臭的一些基本情況：

　　問題始于口腔。以色列特拉維夫大學(Tel Aviv University)人體微生物學教授、國際鼻息氣味研究組織(International Society for Breath Odor Research)聯(lián)合創(chuàng)始人梅爾?羅森伯格(Mel Rosenberg)指出，多數(shù)情況下，口臭是由細菌滋生引起的，而這種細菌滋生多半發(fā)生在舌后部，即后鼻滴涕匯集處。

　　細菌還容易在牙齒與牙齦之間滋生，產(chǎn)生硫化物和其他惡臭化合物，包括腐肉中含有的腐胺和帶有類似汗腳臭味的異戊酸。

　　有時候，口臭還可能來源于鼻腔，一般由鼻竇阻塞所致。羅森伯格博士舉例道，如果小孩子的口氣突然變得不清新，那很可能需要檢查一下鼻腔中有沒有異物。

　　但口臭也可能源于大腦。在找牙醫(yī)或到診所看口臭問題的人群中，大約有四分之一的人實際上患的不是口臭，而是口臭恐懼癥。羅森伯格博士稱，“這些人的父母、子女或朋友患有口臭，導致他們認為自己也患有口臭?！弊晕腋杏X口味不佳并不意味著就有口氣。

　　要了解自己到底有沒有口臭，不是通過舔一下手腕、向手心吹氣或者把頭埋到毯子下面吹氣來判斷的。一些牙醫(yī)會使用“口氣儀”檢測呼吸中硫化物的含量。當然，還有一個更簡單的方法：問問一個信得過的朋友或者家人。

　　消除口臭的最佳方法包括定期刷牙漱口，清除牙垢，以及用刮舌器清潔舌后部。(口腔清新噴霧劑或薄荷糖一般只能暫時掩蓋口氣問題。)用漱口液也會有幫助，但一些漱口液含有酒精，會導致口腔干燥，令口氣問題惡化。

　　大量飲水和保證早餐規(guī)律──最好多吃全麥面包之類的粗糧，這樣有助于促進夜間滋生的細菌的流動。羅森伯格博士說，“只要吃早餐，就可以令口腔中的揮發(fā)性硫化物至少減少70%。”

　　你的檢查結(jié)果怎么樣

　　How is the result of your lab test?

　　你的檢查結(jié)果怎么樣?

　　When it comes to that, I have a lot to say.

　　說來話長了。

　　Then say it.

　　說來聽聽。

　　When I went back to my doctor to hear the results of my lab tests, I tried to keep a poker face even though I was scared to death. Then you guess what he said.

　　我去醫(yī)生那兒看化驗結(jié)果的時候，我害怕得要死，不過我還是裝硬作沒有事兒一樣，你猜他怎么說。

　　That’s just what I want to know.

　　我想知道的就是這個呀。

　　He told me the tests were negative and there was nothing wrong with me.

　　他說結(jié)果是陰性，我沒事兒。
