The present concept of health requires the inclusion of psychosocial aspects, such as issues related to quality of life (QoL), which is closely related to the human relationships in the contemporary society. The idea of “quality of life” has been expanded recently, and its improvement has also become a goal of the good practices for health promotion and prevention of disease.Oral health cannot be dissociated from general health and it is essential to quality of life. Pain and discomfort because of oral health problems are a second component of children’s Oral Health Related Quality of Life (OHRQoL). Psychological factors, in particular whether children like the appearance of their teeth and how oral health affects their self-esteem, are a third aspect of children’s OHRQoL.The use of indicators of OHRQoL in children is necessary since they are based on self-perception and oral health impact, which is essential for planning of actions for health promotion considering biological and psychosocial aspects. It is also suggested the need of studies using quali-quantitative methods as an alternative approach to the use of OHRQoL instruments in children.
