This book, "Oral Health Related Quality of Life" is an insight of how oral health can affect social and psychological aspects of individual and community at large. Quality of life is a relatively new concept in the field of health and has huge impact on dental/oral health. Traditionally, dental health outcomes have been conceptualized in terms of clinical indicators of oral health status or measures of oral pathology. Until recently, little attention has been given to discerning about how dental condition and their treatment impinge upon social or psychological functioning.
