牙龈炎口臭患者主要病原微生物的检测及意义
Shaanxi Medical Journal(2008)
Abstract
目的:评价牙龈卟啉单胞菌(Pg)和螺旋体(S%)在牙龈炎口臭形成中的作用.方法:对39例牙龈炎患者用鼻闻法分为口臭组和无口臭组,其中口臭组29例(HG),无口臭组10例(NHG),用Halimeter检测挥发性硫化物(VSCs),厌氧培养检测牙龈卟啉单胞菌和刚果红负性染色剂涂片计算螺旋体.结果:①牙龈炎口臭组和无口臭组牙龈卟啉单胞菌和螺旋体检出率无显著性差异(P>0.05),但构成比实验组显著高于对照组(P<0.05);并且龈下菌斑中,实验组构成比显著高于对照组(P<0.01),舌苔菌斑中,口臭组高于对照组(P<0.05).②在龈下菌斑中OR值与Pg和S%呈明显正相关(P<0.01),在舌苔菌斑中OR值与S%呈正相关(P<0.05),与Pg无相关关系,在龈下菌斑中VSCs与Pg和S%呈相关(P<0.05),舌苔菌斑中VSCSs值与g和与S%无相关关系.
