The present article aimed to describe the foundations and adequacy of the Grounded Theory (GT) to the construction of the substantive theory on the phenomenon of oral health care of institutionalized elderly people. GT is a methodology that allows formulating orderly abstractions from the real life data. Through this referential is possible to elaborate a relevant and functional theory in order to understand the meaning of the elderly oral health care practices. GT allowed an extensive and rich production of information codes submitted to a process of Comparative Analysis. The immersion in the actors' subjective and private view, through interviews performed with the participants, allowed by the open and flexible character of the method, permitted the formulation of comprehensive analysis categories. The text demonstrates the validity of this alternative methodology to the scientific investigation of this complex phenomenon.
