ABSTRACT
Objective and

background:

Periodontitis is an inflammatory disease which is characterized by a progressive loss in the matrix of soft and hard tissue of periodontium particularly the collagen fibers which are cleaved by matrix Metalloproteinase (MMP). Indeed, increased activity of MMP mediates progression of periodontal diseases but population-based genetic variations could determine the susceptibility to the disease. The aim was to investigate association between MMP-1-1607 polymorphism with periodontitis among Iraqi individuals. Subjects and

methods:

The design of this study was a case-control for Iraqi individuals who were divided into two groups; periodontitis group (cases) and those with healthy periodontium (Control). For each subject, clinical periodontal parameters and demographic characteristics were recorded and venous blood was withdrawn for genetic analysis of MMP-1 by using PCR technique and DNA sequencing.

Results:

Analysis of MMP-1-1607 genotypes, by Hardy-Weinberg equilibrium, showed significant differences in the total sample. The most predominant MMP-1-1607 genotype among Controls was 1G/2G which was significantly different from periodontitis cohorts. Overall, 13 SNP were detected in periodontitis group versus 17 SNP in Control group. In addition, the periodontitis group showed a significant negative association between the probing pocket depth and MMP-1-1607.

Conclusion:

Results suggested that polymorphisms in MMP-1-1607 1G/2G may play a protective role and decreasing the susceptibility to periodontitis. (AU)
RESUMO
Introdução e

objetivo:

A periodontite é uma doença inflamatória caracterizada pela perda progressiva da matriz dos tecidos moles e duros do periodonto, particularmente as fibras de colágeno clivadas pelas metaloproteinases da matriz (MMPs). De fato, o aumento da atividade de MMPs medeia a progressão das doenças periodontais, mas as variações genéticas baseadas na população podem determinar a suscetibilidade à doença. O objetivo foi investigar a associação entre o polimorfismo MMP-1-1607 e periodontite em indivíduos iraquianos. População e

método:

O desenho deste estudo foi um caso-controle com indivíduos iraquianos, os quais foram divididos em dois grupos grupo periodontite (casos) e indivíduos com periodonto saudável (controle). Para cada sujeito, os parâmetros clínicos periodontais e as características demográficas foram registrados, e o sangue venoso foi coletado para análise genética de MMP-1 por meio da técnica de PCR e sequenciamento de DNA.

Resultados:

A análise dos genótipos MMP-1-1607, pelo equilíbrio de Hardy-Weinberg, mostrou diferenças significativas na amostra total. O genótipo MMP-1-1607 mais predominante entre os controles foi 1G/2G, o qual foi significativamente diferente das coortes de periodontite. No geral, 13 SNP foram detectados no grupo periodontite versus 17 SNP no grupo controle. Além disso, o grupo periodontite mostrou uma associação negativa significativa entre a profundidade da bolsa de sondagem e MMP-1-1607.

Conclusão:

Os resultados sugerem que polimorfismos em MMP-1-1607 1G/2G podem desempenhar um papel protetor e diminuir a suscetibilidade à periodontite. (AU)
