Abstract

Periodontal data are usually plentiful observations made in one oral cavity. In order to describe the periodontal situation, sites (gingival units) around teeth within patients or subjects are considered by using several variables. Observations may be even repeated in a longitudinal way. This is a typical hierarchical situation with lower and upper levels.
