研究目的:

本研究通过16S rDNA高通量测序技术,对上颌快速扩弓前后口呼吸儿童及健康儿童鼻腔微生物菌群变化情况进行调查,通过分析儿童鼻腔微生物的物种多样性、物种组成、物种差异,探讨RME对口呼吸儿童鼻腔菌群微生态的影响。  

Objectives of Study:

This study aimed to investigate changes in the nasal microbiota of children with oral breathing before and after RME treatment compared to healthy children using 16S rDNA high-throughput sequencing technology. By analyzing species diversity, composition, and interspecies differences in the nasal microbiota, we sought to explore the impact of RME on the nasal microbial ecology of children with oral breathing.
