NEVES, Anagélica Madeiro; PASSOS, Isabela Albuquerque  and  OLIVEIRA, Andressa Feitosa Bezerra de. Gingivitis prevalence and severity study among low socioeconomic status population. Odontol. Clín.-Cient. (Online) [online]. 2010, vol.9, n.1, pp. 65-71. ISSN 1677-3888.

The aims of this study were to determine the gingivitis prevalence and severity in low socioeconomic status children of 7-12 years old. One hundred and seventy six students aged 7 to 12 years from public school were examined. The indexes used were: BI (Bleeding Index) and PVI (Plaque Visible Index). The socioeconomic status was determined according family income and the socioeconomic class. Exact test of Fisher, Anova oneway and the correlation of Pearson were used. The gingivitis and visible biofilm prevalence were of 97.2%, being the more frequent the light form (89.8%). The mean±SD of BI and of BVI was of 8.26±6.5% and 10.39±8.17%, respectively. The children had a high toothbrush frequency (70.5%) and absence of flossing use (92%). Negative correlation was observed between age, IPV and ISG. In relation to the income, 53.3% of the children were in the poverty line. The examined children presented a high light gingivitis prevalence, especially of the light form, instead of the high toothbrush frequency related.
