Detection of in subgingival biofilms of healthy, gingivitis, and chronic periodontitis subjects.

Background: is a Gram-positive, facultative anaerobic coccus that can survive under harsh conditions. Studies have shown a positive relationship between biofilm formation and gelE gene expression in . The production of gelatinase (MMP 2) has been detected in 50% of isolates from endodontic and periodontal infections, which suggests its role in the pathogenesis of apical and marginal periodontitis.

Evaluation of Periodontal Status among Men Undergoing Infertility Treatment.

Aims: It has been estimated that >30% of male infertility cases are of idiopathic etiology. Recent studies revealed a positive connection between periodontal pockets and sperm submotility, which proposes that periodontitis may have a role in male infertility and inadequate semen quality. The aim of the present investigation was to inspect the relationship between male fertility parameters and the periodontal status of male patients attending treatment (IVF) clinic.
