Abstract

The aim of this work was to verify the prevalence and severity of periodontal disease in patients between 9 anel ll years old from the Paecliatric Dentistry Clinic of the Federal University of Paraíba, relating the levels of disease with gender and biofilm accumulation. The sample was composed by 64 children that were in attendance on this Clinic. One examiner carriecl out the exam.

The data were submitted to a statistical analysis with the aid of the SPSS program and treated by the tests of the Qui-square and Exact of Fisher (p <0,05). The results show the following prevalence: gingivitis 100%; recession gingival 21.8%; pocket depth 4.6%. It was observed unsatisfactory oral hygiene levei in 89.1 % and 54.7% of the children by the O'leary and OHLS indexes, respectively.
