蛀牙系點形成-

——蛀牙系點形成嘅? 蛀牙傷及到齒髓嘅神經時,就會引起各種各樣嘅疼痛了。呢時候如果放任唔管唔去醫治嘅話就好有可能會引起好似齒髓炎之類嘅並發症,令到你疼痛難忍。咁蛀牙系點形成嘅?下文請深圳鵬程醫院專家為大家介紹一下。 牙科醫療同預防牙科嘅普及結果顯示,牙科病患調查統計:5歲以上嘅中國人當中有86%嘅人都有蛀牙。蛀牙(醫學上叫做"齲齒"),系由於長時間受到口腔內細菌嘅感染,使齒質被溶蝕損壞嘅病症。隨着飲食生活嘅變化,有蛀牙嘅人越嚟越多了。喺自然界生存嘅動物同喺未開化嘅環境中生存嘅人類幾乎系唔長蛀牙嘅。 蛀牙產生嘅原因歸結起嚟有三個要素,即口腔內細菌嘅作用,常食含糖量高嘅食物,以及容易形成蛀牙齒質,呢三個要素共同作用形成咗蛀牙。食完飯後,如果冇及時地将附着喺牙齒上嘅食物清理干凈,就會使食物嘅殘渣同細菌一齐存留喺牙齒表面。 呢D嘢就系我哋平常睇到嘅牙齒上黑色嘅嘢(即牙菌斑),而喺牙菌斑里有種能把牙齒腐蝕嘅細菌,呢種細菌一方面能分解食物殘渣嘅糖分嚟為口腔內嘅細菌提供養料,另一方面仲可以產生一種酸性物質,而呢種酸性物質將會起到腐蝕牙齒嘅作用。呢種酸性物質可以将牙齒表面較堅硬嘅牙釉質畀腐蝕掉。呢就系所謂嘅脫灰,亦就系蛀牙開始形成時嘅現象。咁不斷地被腐蝕,牙釉質會變得越嚟越薄,慢慢嘅,里面叫象牙質嘅部分亦會被溶解,較後牙神經亦會露出嚟。
