Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries.
Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too.
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation.
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an urgent, organized, social response to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.

(答案→)C 解析：文章大意：槽糕的口腔卫生差导致的社会和情感问题，作者想引起人们对于口腔问题注意并及时采取措施解决它。【小题1】C 细节理解题。根据第二段第一、第二句“Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London.”可知其人是与该机构一起工作，并非该机构的领导者，第二句提到他领导一个研究队，所以A不对；B项提到“cure all major disease”太过绝对且文中并无体现；C项根据第二段第二、第三、第四句可知是正确的；D项提到第四段第一句是说他们一样危险。故不对。【小题2】D 细节理解题。A项根据第三段第一、第二句可知对象误用，排除；B项第三段第一句以及第六段第一句可知是错的；C项提到成为发达国家是错的，应该为“more like western nations”才对；D项从第八段最后一句可以看出：这种疾病将引起心理混乱影响人们的交流。故D正确。【小题3】A 推理判断题。作者写本文就是引起人们关注这种疾病并采取措施处理。故A正确；B项告诉研究结果是片面的观点；C项从第五段看出只是一个观点；D项不是仅仅告诉医生所以不对。【小题4】B 事实细节题。从文章结构来看，先提出问题然后提出解决办法，说明作者是持着关心的态度来写的。故B正确。考点: 健康保健类短文阅读。
