Modified OXIS Classification of Interproximal Contacts of Primary Canines and Its Prevalence in Six-to-Nine-Year-Olds in the Delhi National Capital Region: A Cross-Sectional Study

Based on the current study, the most common contact type observed was type I, followed by type S1, according to the modified OXIS criteria. The findings indicate a higher prevalence of closed-type contacts in this population, suggesting that the occurrence of such contacts increases as permanent teeth erupt. This tool may be useful for assessing caries risk in this age group.
