牙周膜炎是怎麽發生的

牙周膜炎是怎麽發生的

   牙周膜炎是怎麽發生的?牙周膜炎可發生于日常生活中,包括正常咀嚼食物在內所發生的牙周膜損傷,如食物中帶骨食品、米飯中的石子和棗核等。也可以發生于修複不當的牙齒,如充填物較高和修複體基牙受力過大時,還可以發生于正畸牙時加力過大。通常將不同因素所致的牙周膜損傷統稱爲外傷性牙周膜炎。任何原因引起的牙周膜炎,都可産生疼痛。牙痛程度爲只要不觸及患牙,疼痛尚可以忍受;一旦觸及患牙,立即引起不可忍受性疼痛,因此牙周膜炎既不能承受咀嚼又不能接受冷熱刺激。上述症狀均爲牙周膜充血損傷反應性症狀表現。關于牙周膜炎時可能出現的自發痛和根尖周牙周膜損傷疼痛問題,必須與牙髓炎症時的疼痛相鑒別。牙周膜炎的自發痛有時難以與牙髓炎時自發痛相區別,但引發自發性牙痛的病因可作爲鑒別要點,同時自發痛並發症也能協助診斷。有時出現異常疼痛時則可懷疑根尖部牙髓的血管神經受到損傷的問題。除了牙齒疼痛之外,患牙還出現輕度松動,在不能排除牙根折斷等問題發生時,確切診斷常需X片檢查確定。輕度牙周膜炎,一般服用鎮痛、消炎藥物7~第10天可好轉,患牙短期不承擔咀嚼,使其得到休息,必要時墊高健康鄰牙。對于嚴重損害,除常規治療外,牙齒松動時則需要結紮固定。
