Association of matrix metalloproteinases (MMPs) gene polymorphisms with periodontitis: a systematic review.

Matrix metalloproteinases (MMPs) are proteinases released by gingival cells, macrophages and neutrophils, induced by potentially pathogenic periodontal bacteria of the subgingival plaque, which play a critical role in the pathogenesis of periodontal disease. The expression of MMPs is controlled by chromosome 11. Single nucleotide polymorphisms (SNPs) are linked with variations in the secretion of MMPs, resulting in periodontal disease progression. Genetic studies aim to find the markers for early diagnosis and prevention of the related diseases. This systematic review focuses on finding the association between the MMPs and periodontitis among Indians. A literature review was performed, including studies published between January 1 2012 and May 2024 were incorporated. This systematic review included 1,046 participants in seven Indian studies, and substantial evidence was found for an association between MMP-9 (-1562C/T) and periodontitis in Indian population.
