Summary
Lactobacillus plays a dual role in dental caries, exhibiting both cariogenic and potential probiotic properties. Further research is needed to fully understand its impact on oral health and microecology.
Area of Science:
- Microbiology
- Oral Health
- Dental Caries Research
Background:
- Lactobacillus is strongly associated with dental caries due to its acid production, acid tolerance, collagen binding, and extracellular polysaccharide synthesis.
- Some Lactobacillus strains possess inhibitory effects against cariogenic bacteria through various mechanisms, including producing antibacterial compounds and competing for adhesion.
- Recent research explores Lactobacillus as a probiotic for caries prevention, but its full cariogenic and probiotic mechanisms require further investigation.
Purpose of the Study:
- To review the current understanding of Lactobacillus's role in dental caries development.
- To explore the potential of Lactobacillus as a probiotic agent for caries prevention and control.
- To highlight the need for comprehensive research on Lactobacillus's effects on oral and systemic microecology.
Main Methods:
- Literature review and synthesis of existing research on Lactobacillus and dental caries.
- Analysis of studies investigating the cariogenic mechanisms of Lactobacillus.
- Evaluation of research on the probiotic potential and clinical applications of Lactobacillus in caries prevention.
Main Results:
- Lactobacillus contributes to dental caries through acidogenicity, aciduricity, and promoting bacterial adhesion.
- Certain Lactobacillus species demonstrate potential in inhibiting cariogenic bacteria and could be used as probiotics.
- Significant knowledge gaps exist regarding the complete cariogenic mechanisms and the impact of specific Lactobacillus strains on oral and intestinal microecology.
Conclusions:
- Lactobacillus has a complex role in dental caries, acting as both a causative agent and a potential therapeutic agent.
- Further research is essential to elucidate the dual properties of Lactobacillus and its comprehensive effects on oral and systemic health.
- Integrating knowledge of both cariogenic and probiotic aspects of Lactobacillus is crucial for developing effective strategies for dental caries prevention and control.
