Anti-bacteria function of compound ornidazole-rhubarb buccal film

OBJECTIVE To observe the antibacterial function of compound ornidazole-rhubarb buccal film(CORBF),its local delivery and desorption.METHODS Caries and periodontitis-associated bacteria were chosen.Paper-disc assay was used to test the sensitivity of bacteria to the buccal film,and lamina aflixa assay was applied to analyze the anti-bacteria action and desorpdon of the buccal film.RESULTS Compound ornidazole-rhubarb buccal film had significant anti-bacteria action on P.g and other bacteria.And it could inhibit the absorption of S.mutans.CONCLUSION Compound ornidazole-rhubarb buccal film has a stable inhibitory effect on caries and periodontal bacteria.
