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.
一项新的研究表明,与生活在2000年前的人相比，现在的人们有更多的牙龈疾病。这项研究由伦敦国王学院开展，并在“英国牙科杂志”上发表研究结果。研究人员检查了生活在公元200 - 400年(2200 - 2400年前) 的303人头骨的牙齿。头骨是在英格兰西部一个古老的墓地被发现的。研究人员发现,只有5%的头骨显示有牙龈疾病的迹象。现在英格兰30%以上的人有牙龈疾病。教授弗朗西斯·休斯对他的发现感到吃惊。他说,古时候的人们没有牙刷和牙膏,没有看过牙医,与我们现在的状况完全不同。
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.
