Deep caries of deciduous teeth root canal bacteriological analysis

The purpose of this study is to analyze with deep caries of primary teeth root canal bacteria. Methods 12 deep caries of deciduous teeth, of which three have hot and cold to stimulate the pain, the remaining nine had no clinical symptoms in the micro-aerobic and anaerobic under the risk of root canal bacteria isolation and identification. results show symptoms of teeth colony forming units higher than the asymptomatic teeth, but no significant differences between the two in both groups, the similar composition of the root canal bacteria and of deep caries bacteria Streptococcus mutans and Lactobacillus accounted for the proportion of culturable bacteria than other bacteria, the difference was significant, and Streptococcus mutans and Lactobacillus detection rate is dental equipment higher than other bacteria, the difference was also significant obligate anaerobes, such as digestive the Streptococcus, Wearing Shi bacteria, Fusobacterium and Prevotella has also been detected, but its detection rate and accounted for the percentage of cultures were very low. Conclusion microaerophilic cariogenic the bacteria of milk Keywords: deciduous teeth with deep caries root canal bacteria

Is generally believed that deciduous dentine is thin, the poor degree of mineralization, deep caries infection can easily spread to the pulp, the clinical treatment of deep caries often to save the teeth for the purpose of the preservation of life pulp not pay enough attention to. Save the vital pulp of deciduous and permanent teeth induction of great significance, the pulp is closely related to Correction extraction of six problems some extent, and it’s within the number and types of microorganisms. Looking reported in the literature, few studies on deciduous teeth with deep caries microbiology, this study attempts to learn deciduous teeth with deep caries pulp microbial analysis for clinical treatment, bacteriology reference.
