The greatest limitation of traditional epidemiological indicators is their inability to reflect the “capacity of an individual to perform tasks and activities”13. Self-perceived measures convey more information about the way a certain disease is affecting the individual’s daily routine and the population in general than the measurements collected from a clinical environment5. Clinical indicators are important for the assessment of oral health and treatment needs; nevertheless, their limitations must be considered11. The combined clinical and subjective indicators define a multi-dimensional assessment of the oral health condition1. Locker10 (1998) explains that the quality of life indicators related to oral health were defined.
