Profile

Research Description

My research activity has been developed around three major themes: 1) on the development and evaluation of measures of oral health-related quality of life, and research on their use for needs assessment and planning services, 2) on social determinants of oral health and the relationship between oral and general health, 3) on the effect of oral health on diet and nutrition.

Research Activities
