- 再生医学是一种再生医学.
- 口腔微生物学 口腔微生物学
背景情况:
- 牙周缺陷通常需要再生程序.
- 用于牙周再生的最小侵入性手术技术 (MIST/M-MIST).
- 乳矩阵衍生物 (EMD) 用于填补骨缺陷.
研究的目的:
- 为了比较牙周再生的临床,放射学和微生物学的结果,有和没有局部抗生素治疗.
- 通过微创手术评估质矩阵衍生物 (EMD) 在垂直骨缺陷中的疗效.
主要方法:
- 40名垂直缺陷患者被随机分为测试 (SRP+ANB+MIST/M-MIST) 和控制 (SRP+MIST/M-MIST) 组.
- 在手术前和6个月后对牙周参数和放射图进行了评估.
- 用PCR分析下斑块样本进行微生物学分析.
主要成果:

01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
