Abstract

Aging is a normal process, as inevitable biologicalphenomenon. Generally, this process characterizedby a decrease in the ability of resolution,regeneration, and reparation of cell and tissues, So,those cells and tissues cannot function properly andits will grow up and die.(1) WHO reports that thepopulation of elderly people worldwide increases by1.7% annually, whereas the population of peopleaged ≥ 65 years old increases by 2.5%. WHOclassified the elderly based on their chronologic/biologic state in 4 groups: (1) the middle age ranged45-59 years old, (2) the older/elderly age ranged 60-74 years old, (3) the advanced old age ranged 75-90years old, and (4) the very old age over 90 years old.Generally, elders ≥ 65 years old have healthproblems as effects of aging process. That meansthey need to have a special concern about theirhealth condition include in dental care.(2,3)Low, systemic and progressive chronic inflammationin elderly age is called inflammaging. This conditioncan occur as the effects of injury on cells andtissues.(4,5) There are some factors that cause injuryon cells, such as; hypoxia, chemical materials (toxins,drugs), physical agents (mechanical trauma,temperature, sudden changes in atmosphericpressure, radiation, electrical potency), microbiologyagents (virus, microbes, fungi), immune systemdisorder, genetic disorder, or malnutrition. Whenthe cells got injuries, there are some possibilityreactions on cells and tissues, e.g. retrogressivereaction, progressive reaction; and adaptationreaction. The main cause and the response towardsinflammaging that linked to illness are stillunknown.(6)

Abstract

Osteogenesis is a process of development which is perfectly controlled by a number of extrinsic and instrinsic factors that consists of hormones, growth factors, cytokines produced in the bone marrow micro environment, due to process of molecules adhesion that mediate by the interaction of cells and cell-matrix, osteoblasts-specific signaling proteins and transcription factors (TFs). Recently, research explained that adherence osteoclasts on the bone surface and secretion of protons into an extracellular compartment between osteoclasts and bone surface together with the production of Reactive Oxygen Species (ROS) involved in the complex process of bone resorption. Superoxide role in the activation and transcription NF-κB factor is to increase osteoclastogenesis. Furthermore, it is alleged that ROS is involved in both differentiation of osteoclasts and osteoblast cell. Aging and diseases which associated with aging is a result of ROS that cause damage was reported increase with age. This review, which is dedicated to geriatric physicians, geriatric dentistry or gerodontology reviews ROS-related osteoclastogenesis in aging and as the basic of the research to determine benefit of ROS through NADPH oxidase activation in the osteopetrotic case.
