Association Between Matrix Metalloproteinase-1 −1607 1g/2g Polymorphism and Chronic Periodontitis in Indonesian Population

Abstract

Objective: This study aimed to identify the distribution of matrix metalloproteinase (MMP)-1 −1607 1G/2G alleles and genotypes in subjects withchronic periodontitis and healthy subjects in a sample of Indonesian population and assess the possible association of this polymorphism withsusceptibility to chronic periodontitis.Methods: Genomic DNA samples were obtained from 200 Indonesian males aged 33–78 years old, comprising 100 chronic periodontitis patientsand 100 healthy controls. DNA fragments were amplified by a polymerase chain reaction and analyzed by restriction fragment length polymorphism.Results were analyzed by Chi-square test.Results: The frequency of the 2G allele was high both in subjects with periodontitis (87%) and in controls (91%). Analysis of MMP-1 genotype(−1607 1G/2G) showed no significant difference between the chronic periodontitis and healthy groups (p>0.05).Conclusion: The result found no association between MMP-1 −1607 1G/2G polymorphism and susceptibility to chronic periodontitis in Indonesiansubjects.
