大家都知道"早晚刷牙，不长蛀牙"，但一些小伙伴可能会问："为什么一天要刷两次牙？""懒人只想刷一次，早上刷好还是晚上刷好？" 今天就告诉你为什么一天要刷两次牙？为什么晚上刷牙不能省？ 为什么每天至少刷两次牙？ 口腔健康的两大公敌：龋病（蛀牙）和牙周病（老掉牙），都是由长期附着在牙齿表面的细菌不断堆积繁殖，持续破坏牙齿和牙周支持组织导致的。 但是这些细菌并不是一开始就牢牢地粘在牙面上了，形成稳定成熟的菌斑需要一个过程： 一阶段——初期附着（0—2小时）当你刚刷完牙，其实新的牙菌斑就又开始形成了，但这时候只有少量松散的细菌借助唾液薄膜附着在牙面上。 二阶段——细菌附着（2—12小时）越来越多的细菌通过与唾液膜相互作用附着在牙面上，并且比一阶段更牢固。 三阶段——成熟菌斑（12小时后）附着的细菌开始繁殖代谢并形成复杂的生物膜结构，菌斑逐渐成熟。成熟的菌斑结构更加紧密，难以通过简单的刷牙去 除。 四阶段——完全成熟（24小时后）经过24小时，牙菌斑完全成熟，形成一个复杂的微生物群落。此时的菌斑对口腔健康威胁很大，容易引发龋齿和牙周疾 病。 从菌斑成熟的过程和时间可以看出，通过刷牙机械摩擦和牙膏辅助清洁，能够去除牙面上 ...

新华社北京9月18日电（记者李佳巍）"一直早刷晚刷，足够重视，为啥牙齿还是老出问题？"时不时响起"警报"的牙齿健康，让不少一天两次"按 时足量"刷牙的网友疑惑不解。 陕西省西安市新城区通济坊小学的学生在西安交通大学口腔医院口腔科普教育基地学习正确的刷牙方法。新华社记者 李一博 摄 横向"拉锯式"刷牙，错！ "众多牙病患者都存在牙齿楔状缺损问题，而长期错误地横向'拉锯式'刷牙正是罪魁祸首。'越用力刷牙越干净'是个误区，这个举动就像拿砂纸磨 损牙颈，对牙齿造成的损伤不可逆。"北京大学口腔医院预防科主任医师荣文笙说。 为何刷牙不能横向"用力过猛"？专家介绍，牙釉质是人体最坚硬的组织，是保护牙齿的"盔甲"，但其厚度呈"山峰-山谷"分布，即牙冠部（咀嚼 面）最厚，牙颈部（牙龈边缘）最薄。横向刷牙时，刷毛与牙齿形成45°角切割力，长期作用就像用钢锉反复摩擦薄弱的"山谷"。 荣文笙说，许多人日常习惯侧重牙齿表面清洁，喜欢刷"顺手"的地方。而对于牙齿缝隙处往往忽视，清洁难以触达牙龈边缘、牙间隙等部位，这 一清洁"盲区"往往成为牙菌斑滞留重灾区，给"蛀牙刺客"邻面龋发生以及牙周疾病的发展提供了繁衍温床。 牙周病是影响我国居民口 ...

Core Viewpoint - The article highlights the success story of Shaodong, a small city in Hunan, China, which has become the world's largest lighter production base, producing approximately 15 billion lighters annually and generating nearly 15 billion yuan in output value. The city has maintained a stable price of 1 yuan for its lighters for 20 years, showcasing effective cost control and innovation in production processes [4][12][28]. Group 1: Industry Background - Shaodong's lighter industry emerged as a result of a shift from the coastal city of Wenzhou, which faced challenges due to international market barriers and regulations [8][13]. - The lighter market was historically dominated by Western brands until Chinese manufacturers, particularly from Wenzhou, began to produce affordable alternatives, leading to a significant market share [11][12]. - The decline of Wenzhou's metal lighter industry due to regulatory challenges opened the door for Shaodong's rise in the injection-molded lighter segment, which began to flourish in the early 2000s [15][16]. Group 2: Key Success Factors - Shaodong's success can be attributed to three main strategies: focusing on technology and craftsmanship to enhance product value, selecting the right market segment, and fostering collaboration among local manufacturers [18][22][26]. - The city has shifted its focus from low-cost production to higher-value products, with exports to Europe and the U.S. reaching a total value of 440 million yuan in 2022 [21][22]. - Shaodong's lighter industry benefits from a well-established supply chain, with over 120 related enterprises providing components and services, allowing for rapid production and cost efficiency [23][25]. Group 3: Pricing Strategy - Despite rising costs in land, materials, and labor, Shaodong has maintained the price of its lighters at 1 yuan for two decades, achieving this through stringent cost control measures [30][31]. - Automation and technological upgrades have significantly reduced production costs, enabling higher output with fewer workers, thus maintaining profitability even at a low price point [33][39]. - The concept of economies of scale plays a crucial role, as increased production volume leads to lower average costs, allowing Shaodong to sustain its pricing strategy effectively [34][35]. Group 4: Broader Implications - The success of Shaodong's lighter industry exemplifies how small products can lead to substantial economic impact, reflecting a broader trend in China's manufacturing sector where low-cost, high-volume production can compete globally [37][41]. - Similar success stories exist in other regions of China, such as the toothbrush industry in Yangzhou and the makeup brush industry in Henan, indicating a pattern of small towns leveraging niche markets for significant economic contributions [36][38].
