Summary
Genetic risk scores show promise in predicting periodontitis. A higher genetic risk score (GRS) was associated with more severe and diffused forms of periodontitis, suggesting its potential for early detection.
Area of Science:
- Genetics
- Periodontology
- Oral Health
Background:
- Single nucleotide polymorphisms (SNPs) influence host response in periodontitis.
- Individual SNP effects are small, necessitating combined analysis.
- Genetic risk scores (GRS) are proposed to aggregate small genetic effects.
Purpose of the Study:
- To evaluate the predictive capability of genetic risk scores for periodontitis onset and progression.
- To assess if GRS can differentiate between various forms of periodontitis.
Main Methods:
- DNA isolation from oral epithelial cells of 50 patients.
- Analysis of selected single nucleotide polymorphisms (SNPs).
- Calculation of a genetic risk score (GRS) using an additive model.
Main Results:
- A significant association was found between TNF rs1800629 and diffused periodontitis.
- The GRS effectively discriminated between diffused and localized periodontitis forms.
- An increasing GRS correlated with advanced periodontitis stages compared to early stages.
Conclusions:
- While individual genetic polymorphisms have shown limited success in predicting periodontal disease susceptibility.
- The study suggests that genetic risk scores (GRS) offer a promising approach.
- Further research incorporating multiple genes is recommended to validate these findings.

01:11Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
