Oxidative stress state is involved in the aging process as well as in a vast array of pathological conditions, including atherosclerosis, cardiovascular complications, diabetes, cancer, and neuropsychiatric and neurodegenerative diseases. Oxidative stress is characterized by an imbalance in the cellular redox state in favour of a high formation of reactive oxygen species (ROS), overcoming the reducing capacity of the human antioxidant defence system, which has the role to eliminate excess ROS production, avoiding the oxidative action of such species on cellular components (nucleic acids, lipids, proteins or carbohydrates) and thereby their resulting adverse effects. . | ORAL HEALTH CARE -PEDIATRIC RESEARCH EPIDEMIOLOGY AnD CLINICAL PRACTICES Edited by Mandeep Singh Virdi Oral Health Care - Pediatric Research Epidemiology and Clinical Practices Edited by Mandeep Singh Virdi Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
