Introduction FADS1 (fatty acid desaturase 1) gene polymorphism results in more susceptibility to certain metabolic diseases and chronic inflammatory diseases like periodontitis. This study aims to analyze the association between FADS1 gene polymorphism and various stages of periodontitis. Materials and methods One hundred subjects included in the study were categorized into two groups: group A (n = 50) had healthy periodontium, and group B (n = 50) had ≥stage II periodontitis. They were graded based on the clinical parameters of probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing (BOP). Five milliliters of venous blood were collected, and DNA isolation was done. Genomic DNA was extracted. The DNA was then subjected to amplification with the help of specific primers flanking the I (PstI) polymorphic site of the FADS1 gene. A chi-square test aimed to examine the genotype and allele frequency distributions in both groups; p < 0.05 was considered statistically significant. Results The difference in genotype frequency of FADS1 polymorphism was statistically insignificant (p = 0.91). Our study revealed no significant difference (AA vs. AG+GG) between the periodontitis and control groups between homozygous and heterozygous variant genotypes with a p-value of 0.7764. The frequency of AG (28% vs. 30%) and GG (62% vs. 58%) genotypes showed no significant difference between the periodontitis group and healthy control subjects. No significant difference was seen in the G allele (77% vs. 73%) and A allele (23% vs. 27%) between the periodontitis and control groups. Conclusion The study concluded that FADS1 receptor polymorphism is not associated with periodontitis in the study population.
