1、精选优质文档-倾情为你奉上广播稿全国爱牙日专题 A:亲爱的老师，同学们大家早上好！雏鹰广播站现在开始播音。我是*，今天和我一起为大家广播的是*同学。 B：大家好，我是*。今天是9月20日，全国爱牙日。口腔健康是全身健康的重要组成部分，是维系和提高生命质量的重要因素。因此，口腔健康不仅使人能充分地咀嚼，享受美味佳肴，为身体提供充足的营养；口腔健康不仅使人口齿清晰，尽情表达自己的意愿，自由地与人交流；口腔健康不仅使人增强自信，在社会舞台上充分地展现自我；所以，口腔健康才能使我们活得更健康，更愉快，更长寿。A：同学们，要想保护牙齿，首先要了解牙的构造。牙是人体中最坚硬的器官。有咬切、撕裂、研磨食物和
2、协助发音等功能。人的一生有两副牙：一副为乳牙，共20个，上、下颌各10个。在出生后约半岁左右开始萌出，两岁半左右出齐，自7至12岁期间，乳牙先后脱落；另一副为恒牙，共32个，上、下颌各16个，自6岁起，逐渐为乳牙更换，至12岁前后除第3磨牙外，恒牙全部萌出。第3磨牙一般在20岁以后萌出，又称智齿。智齿也可终身不出，因此恒牙2832个均为正常。B：龋齿，是少儿常见的多发病，俗称“虫牙”，又叫“蛀牙”，其实它并不是被虫啃坏的牙，而是被一种叫蛀牙菌的细菌在吃了附在我们牙齿表面的残渣之后制造出来的酸性物质所腐蚀引起的。由于我们平时不注意口腔卫生，让食物残渣留在牙缝中发酵，产生酸性物质腐蚀牙齿的釉质，久
3、而久之，形成空洞，使龋齿肿胀发炎，引起疼痛，从而形成了龋齿。A：龋齿影响同学身体健康，又很痛苦，同学们应很好保护牙齿，不让它得病，要做到以下几点。1、养成良好的卫生习惯，做到早晚刷牙，饭后漱口。刷牙是清洁口腔，洗净牙齿，按摩牙龈，增进牙周组织健康的最好方法，刷牙能达到清除食物残渣防止牙垢沉积，减少口臭，清洁口腔的目的。2、刷牙最好用保健牙刷，保健牙刷刷头小，毛囊为两排共12束。这样的牙刷使用灵便，易于清洁牙齿，既经济有耐用。3、牙刷使用一段时间后应更换使用过旧的牙刷刷毛脱落或磨损，容易损伤组织，清洁效果也差。4、牙刷用完后，将刷头朝上放入杯里，不应将刷头朝下或放在密闭容具中，以免细菌繁殖，造成
4、口腔感染。5、要正确掌握刷牙方法。正确的刷牙方法是，顺着牙缝上、下刷，上面的往下刷，下面的往上刷，咬牙合面要来回刷，里里外外都要刷干净。6、纠正错误的横刷法，横刷不易清除牙缝中的食物残渣，而且长期横刷能使牙齿外侧面的牙颈部出现横沟，造成损伤。7、牙膏有清洗去污灭菌爽口的作用，药物牙膏（如含有氟化物、叶绿素、生物素牙膏），对预防龋齿的发生有很好的效果。8、食物应多样化，适当吃些粗粮和富有纤维的食品，这样不仅能使体内获得较全面的营养，而且还能达到锻炼牙齿的咀嚼功能。9、改掉吃零食和睡前吃东西的习惯。吃零食，每次吃后都有一部分食物粘在牙齿上，睡前吃东西，食物残渣能在牙齿上停留10小时而腐蚀牙齿。睡前
5、刷牙后切不可再吃任何零食。10、改掉不良习惯，不咬舌，不咬颊，不吮唇，不咬笔杆，不吮指。用双侧牙咀嚼食物。11、注意摄取与牙齿、骨骼发育钙化有有关的物质，（维生素A、C、D和钙、磷）。12、加强体育锻炼，多晒太阳。慢性腹泻和佝偻病均能造成牙齿钙化不良，应予以重视和积极治疗。13、定期进行口腔疾病检查，这是预防龋齿的好方法。早期发现早期治疗。14、发现龋齿应及时治疗，否则病情发展将影响学习和健康。总之，养成良好的口腔卫生习惯，睡前不吃零食，做到早晚刷牙，饭后漱口，要有正确的刷牙方法，龋齿是完全可以预防的。B：牙疼不是病，疼起来可真要命。我们中的或许有很多同学都受到过牙疼的折磨吧。世界医学组织，把
6、每年的月日定为爱牙日，就是要不断地提醒人们在享受快乐生活的同时，别忘了关注自己的口腔健康，因为它可是直接关系着我们的身心健康和生活品质。除了健康的因素，早在古代，人们就把牙齿的健康美观看成是容貌美观的重要组成部分。爱美之心人皆有之，拥有明眸皓齿，齿如编贝是每个人的心愿。A：“一口洁白、整齐的牙齿，能增添你独特的魅力，让你的生命质量大幅提升，让你的笑容更迷人。”但愿我们每个人都能认识到口腔保健的重要性，都能拥有一口健康的牙齿，拥有更加灿烂的笑容。 A: Dear teacher, classmates Good morning everyone!
