A new study shows that people today havemoregum diseasethan people living2,000 years ago. The study is from the university King's College in London andis published in the 'British Dental Journal'. Researchers looked at the teethin the skulls of 303 people who lived between 200-400 AD (2,200-2,400 yearsago). The skulls were found at an old burial site in the west of England. Theresearchers found that only 5 per cent of the skulls showed signs of gumdisease. Up to 30 per cent of people in England today have gum disease.Professor Francis Hughes was surprised by what he found. He said people did nothave toothbrushes or toothpaste back then and did not visit dentists, like wedo today.

一項新的研究表明,與生活在2000年前的人相比，現(xiàn)在的人們有更多的牙齦疾病。這項研究由倫敦國王學(xué)院開展，并在“英國牙科雜志”上發(fā)表研究結(jié)果。研究人員檢查了生活在公元200 - 400年(2200 - 2400年前) 的303人頭骨的牙齒。頭骨是在英格蘭西部一個古老的墓地被發(fā)現(xiàn)的。研究人員發(fā)現(xiàn),只有5%的頭骨顯示有牙齦疾病的跡象?，F(xiàn)在英格蘭30%以上的人有牙齦疾病。教授弗朗西斯·休斯對他的發(fā)現(xiàn)感到吃驚。他說,古時候的人們沒有牙刷和牙膏,沒有看過牙醫(yī),與我們現(xiàn)在的狀況完全不同。

The main reason why modern people have moregum disease is smoking. Theya Molleson, co-author of the report, said the studyshows that people's oral health has become much worse over the past 2,000 years.She added that she thinks gum disease could startgoing downfrom now as more people stop smoking. She said: "Assmoking declines in the population, we should see a decline inthe numbers of peoplewith thedisease." Gum disease happens when bacteriabuild upin your mouth. The bacteria eat away at your gums and canmake your teethfall out. People canreduce the risk of gum disease by regular brushing, using mouthwash and notsmoking.

現(xiàn)代人有更多牙齦疾病的主要原因是吸煙。邁爾森是這則研究報告的合作者，他說，研究表明，人們的口腔健康問題在過去的兩千年里逐漸變糟。她補充說,她認為牙齦疾病可能會開始減少，因為越來越多的人開始戒煙。她說，隨著吸煙人口數(shù)量的減少,我們應(yīng)該可以觀察到患有牙齦疾病的人數(shù)量減少。牙齦疾病是由于細菌開始在口腔中逐漸積累。細菌侵蝕牙齦，甚至導(dǎo)致牙齒脫落。人們可以通過有規(guī)律地刷牙，使用漱口水，并且戒煙來減少牙齦疾病的風(fēng)險。
