通过44例急性和17例慢性牙髓炎的厌氧消化链球菌检出率比较，探讨了该菌在同一牙病不同类型中的致病作用。
We found that the check rate of this bacteria in acute pulpitis was notably higher than that of in chronic pulpitis (P<0.05).
结果表明：该菌在急性牙髓炎时的检出率显著高于慢性（P＜0．05）。
Results: Coronal pulp tissue of 77.8% of deciduous teeth with deep caries showed chronic inflammation to various degree or chronic pulpitis with acute attack.
