Relationship between oral microbiota and transitional repair effect in children with deciduous teeth caries
[Objective]To investigate the relationship between the oral microflora and the effect of transitional restoration in children with deciduous teeth caries.[Methods]A total of 108 children with deciduous teeth who were treated in Zhumadian Central Hospital from March 2021 to January 2023 were selected as the study objects.According to the degree of deciduous teeth caries,the study subjects were divided into the mild caries group(58 cases)and the severe caries group(50 cases),so as to explore the influence of different degrees of caries on the relationship between oral microflora and transitional restoration effect.Basic information of the patients was collected,including gender,age,orthodontic treatment history,bleeding after brushing,tooth loosening,weak chewing,periodontal treatment history,and family history of periodontitis.Oral bacterial strains were determined,and the relationship between the oral microflora and the effect of transitional restoration in children with deciduous teeth was analyzed.[Results]The proportion of beneficial bacteria such as Streptococcus salivarius,Lactobacillus rhamnosus,Lactobacillus plantarum,Lactobacillus reuteri,Lactobacillus helveticus,Lactobacillus brevis,Lactobacillus lactis,Bifidobacterium,and Lactobacillus paracasei in the mild caries group was higher than that in the severe caries group(P＜0.05).The proportion of harmful bacteria such as Streptococcus mutans,Streptococcus sobrinus,Actinomyces,and Lactobacillus acidophilus in the mild caries group was lower than that in the severe caries group(P＜0.05).The proportion of harmful bacteria after repair was lower than before repair,while the proportion of beneficial bacteria was higher than before repair(P＜0.05).Streptococcus mutans,Streptococcus sobrinus,Actinobacter baumannii,Lactobacillus acidophilus,Streptococcus salivarius,Lactobacillus rhamnosus,Lactobacillus plantarum,Lactobacillus rossiae,Lactobacillus helveticus,Lactobacillus brevis,Lactobacillus lactis,Bifidobacterium bifidum,Lactobacillus paracaseus,and other bacterial strains are factors affecting the oral health of children with dental caries(P＜0.05).[Conclusion]There is a certain correlation between the oral microflora and the effect of transitional restoration in children with deciduous teeth caries,which provides a scientific basis for optimizing the treatment of deciduous teeth caries.Future studies may further explore the influence of different treatment methods on the relationship between oral microflora and transitional restoration efficacy in children with decidary teeth,and the methods to regulate oral microflora,so as to provide a more scientific and effective plan for the treatment of deciduous teeth caries.
