兒童易患齲病原因

Posted By vickong pun     July 9, 2021

兒童處於生長發育時期,牙齒嘅解剖結構等隨年齡嘅增長不斷發生變化,因此,齲病嘅發生、發展喺兒童表現有其特點。  ——兒童易患齲病原因  1.表面釉質未成熟 剛萌出嘅乳牙或恆牙,其表面釉質未完全成熟,初萌嘅牙齒抗酸能力很差,酸蝕極易透過表層向深層發展。  2.乳牙礦化度地 乳牙形成嘅時間短,其礦化度比恆牙低,故乳牙對齲蝕嘅抵抗力更差。  3.解剖特點 乳磨牙嘅頜面窩溝點隙多,喺乳牙鄰面接觸面大,而且存在發育間隙,呢些均有利於食物滯留,菌斑聚集。
患齲病原因  4.飲食特點 兒童由於生長發育而需熱量高,故中意含糖飲食,又因其咀噍力差,偏愛軟質食物,而且進食次數多。  5.口腔衛生差 幼兒唔得自覺地進行口腔衛生,而家長也往往忽略,兒童擦牙缺乏指導和監督,系造成兒童口腔衛生差嘅原因。另外,幼兒嘅瞓眠時間長,口腔處於靜止狀態時,唾液嘅分泌量少,唔利於口腔自潔。
