[Prevalence and severity of gingivitis among scholars (7-14 years): local conditions associated to bleeding on probing].

The objective of this study was to collect data about the prevalence and severity of gingivitis in a sample of scholars, as well as its relationship with possible local risk factors. Two hundred and six subjects were examined, 107 male and 99 female, with age ranging from 7 to 14 years, where data from their Plaque Index (IP), Gingival Index (IG), and Clinical Probing Depth (PCS) were collected. Among all the clinical parameters observed, the mean values found referent to PCS, IP and IG were 1.58 + 0.46, 1.12 + 0.49 and 0.89 + 0.32, respectively. Ninety five subjects (46.1%) presented a diagnostic of slight gingivitis and 111 (53.9%) of moderate gingivitis. Overall, male subjects presented statistically more dental plaque and more gingival inflammation than female subjects. Clinical signs of gingival inflammation were found in all the examined subjects. Gingivitis severity around permanent teeth was directly linked to the amount of dental plaque deposits and to the presence of bleeding on probing.
