About this Research Topic
The oral cavity is a complex system and the point of entry of the digestive system. Many different organs and tissues interact and function together under the constant challenge of microbes, physical and chemical stimuli. The system’s capacity to cope with these various challenges depends in an orderly and regulated response, one that is coordinated at the molecular, cellular and tissular level.
For the last century we have witnessed a worldwide trend for increased life expectancy, and the perspective of an inverted demographic pyramid is on our near horizon. Population’s aging will have an impact in human health and health services. A deeper understanding of the aging process is necessary to provide quality care to an ever-growing cohort of elder patients.
The process of aging or biological senescence disrupts and alters the oral cavity’s capacity to respond and adapt to changes of the environment, giving rise to increase frailty and proclivity to disease. Although natural, biological senescence results in functional and architectural tissue changes that fundamentally modify the adaptive capacity of the system, lowering the threshold necessary to cause harm.
The objective of this Research Topic is to gather in a single source high quality and up to date research regarding oral senescence from different and mutually complementary perspectives, ranging from molecular biology to clinical research.
