| Abstract | Oxidative stress plays an important role in periodontal health and disease. The phagocyte nicotinamide adenine dinucleotide phosphate oxidase NOX2 is most likely one of the key sources of reactive oxygen species (ROS) in periodontal tissues. This review will discuss three clinical aspects of NOX2 function. We will first focus on oral pathology in NOX2 deficiency such as chronic granulomatous disease (CGD). CGD patients are thought to suffer from infections and sterile hyperinflammation in the oral cavity. Indeed, the periodontium appears to be the most common site of infection in CGD patients; however, as periodontitis is also common in the general population, it is not clear to which extent these infections can be attributed to the disease. Secondly, the role of oxidative stress in periodontal disease of diabetic patients will be reviewed. Diabetes is indeed a major risk factor to develop periodontal disease, and increased activity of leukocytes is commonly observed. Enhanced NOX2 activity is likely to be involved in the pathomechanism, but data remains somewhat preliminary. The strongest case for involvement of NOX2 in periodontal diseases is aggressive periodontitis. Increased ROS generation by leukocytes from patients with aggressive periodontitis has clearly been documented. This increased ROS generation is to be caused by two factors: (1) genetically enhanced ROS generation and (2) oral pathogens that enhance NOX function. NOX enzymes in the oral cavity have so far received little attention but are likely to be important players in this setting. New therapies could be derived from these new concepts. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
