Variations in Primary Molar Contact and Approximal Caries in Children: A Three-Year Prospective Cohort Study.

ABSTRACT: Purpose: To evaluate the association between the contact areas of primary molar teeth and approximal caries after three years of observation. Methods: This prospective cohort study included 1,119 caries-free children, aged three to four years, from Puducherry, India. At base- line, 4,476 contacts were assessed using the OXIS criteria, which denotes O for open contact and X, I, and S for closed contacts. X contact represents a point contact, I is a straight contact, and S is a curved contact. Two calibrated dentists measured dental caries at one-year intervals following the International Caries Detection and Assessment System for three years. Poisson regression analysis with a multilevel approach was used to determine the association between contact type and approximal caries.
