根據牙源性化(hua)膿性頜骨(gu)(gu)(gu)(gu)骨(gu)(gu)(gu)(gu)髓炎的臨床病理特別(bie)，病變(bian)(bian)始發(fa)于頜骨(gu)(gu)(gu)(gu)中(zhong)央的骨(gu)(gu)(gu)(gu)松質(zhi)和骨(gu)(gu)(gu)(gu)髓，稱為中(zhong)央性骨(gu)(gu)(gu)(gu)髓炎；病變(bian)(bian)始發(fa)于頜骨(gu)(gu)(gu)(gu)周圍(wei)的骨(gu)(gu)(gu)(gu)膜和骨(gu)(gu)(gu)(gu)皮質(zhi)者，稱為邊緣性骨(gu)(gu)(gu)(gu)髓炎。按其病變(bian)(bian)的性質(zhi)可(ke)分為急(ji)性期和慢(man)性期；按驗(yan)證的范(fan)圍(wei)可(ke)分為局(ju)限型或彌(mi)散型。

　　中央性頜骨骨髓炎：上頜骨較下頜骨多見，患牙劇烈疼痛，為持續性，并沿三叉神經分布區放射痛。患牙及鄰牙松動，有叩痛，前庭溝豐滿，面頰腫脹。下頜骨的牙槽膿腫，膿液不易穿破而得不到引流，發展成急性彌散型骨髓炎。此時患者全身癥狀加重，高燒、寒戰、白細胞增高、脫水及其他中毒表現。
