Abstract

The invention provides a bergenia crassifolia extract and an extracting method and medical application in oral diseases. Through a resazurin dyeing method and an XTT method, the extract of bergenia crassifolia is subjected to bacteriostatic activity and inhibitory biological film activity study, the extract of bergenia crassifolia has an obvious inhibitory effect on streptococcus mutans, streptococcus sanguis, streptococcus salivarius, lactobacillus acidophilus, porphyromonas gingivalis, fusobacterium nucleatum, actinobacillus actinomycetemcomitan and biological film of the fungi, has a better inhibitory effect on streptococcus mutans, porphyromonas gingivalis and the biological film of the fungi and can be used for preparing daily necessities and medicine for preventing and treating the oral diseases.

Description

technical field [0001] The invention provides a rock cabbage extract and an extraction method. The invention further discloses the medical use of the extract in oral diseases, and belongs to the technical field of traditional Chinese medicine pharmacy. Background technique [0002] The occurrence of oral diseases is mainly caused by a bacterial infectious disease caused by the loss of balance of microorganisms in the oral environment. burden. Common oral diseases mainly include dental caries, periodontitis, etc. The main pathogenic bacteria include Streptococcus mutans, Streptococcus sanguis, Streptococcus salivarius, Lactobacillus acidophilus, Porphyromonas gingivalis, Fusobacterium nucleatum and Actinobacillus, etc. According to the survey, the caries rate of deciduous teeth of children in my country is as high as 67.0%, the rate of caries of permanent teeth in middle-aged people is 59.9%, and the rate of edentulous people in the elderly group is 6.9%. General poor healt...
