Introduction: When assessing the oral or hygienic status of a group, community, or population, different assessment systems are used to choose specific teeth and surfaces. A total numerical expression of the hygienic state is calculated and the digital index is called an oral hygiene index. The aim of the study is to describe the relationship between OHI-S and PBI-S in childhood.

Material and Methods: Object of observation. The study is about the oral hygiene status of 60 children aged 6 years. Oral-Hygiene Index, OHI-S Greene and Vermillion (PI / 6 + CI / 6) - (Modified) is used to establish Oral Hygiene status.

Results: Comparison of OHI-S results according to PBI showed the presence of a statistically significant difference (F = 34.63; p < 0.001), with a tendency for OHI-S to increase with an increase in the percentage of PBI-S. In examining the relationship between OHI-S and PBI, an extremely strong direct correlation was found (r = 0.923; p < 0.001).
