Gingival crevicular fluid (GCF) is an inflammatory exudate that can be collected at the gingival margin or within the gingival crevice. The biochemical analysis of the fluid offers a non invasive means of assessing the host response in periodontal disease. Active phase of periodontal disease process can be measured or assessed by the constituents of gingival fluid. Bacterial enzymes, bacterial degradation products, connective tissue degradation products, host mediated enzymes, inflammatory mediators, extracellular matrix proteins either together or individually can be detected in higher levels in gingival crevicular fluid during active phase of periodontitis.

Software development life cycle involves requirement analysis, design, coding, testing and implementation. Software Quality is the most important one, since the success of a Software Engineer relies on the development of failure free software. One of the main quality factors is reliability. Reliability can improve through Software Reliability Models, analyze of reliability data, proper utilization of debuggers, internal quality factors and evaluating the measurement results. Currently, there are several software reliability allocation techniques, but schedule planning and effective resource use are unavailable because they do not support multi-objective optimization. It is an effective software reliability allocation technique that supports multi objective optimization. This approach assists schedule planning as well as effective resources allocation. This paper can aid to increase the effectiveness of resource uses and to establish schedule planning. It will lead to improve Software Reliability.
