[Oral hygiene program on the left bank of the Nervion: its effect on gingivitis].

The effect of monthly professional tooth clearing over gingivitis, without instructions of oral hygiene, was evaluated in a group of 69 children whose ages were from 6 to 12, in the left side of Nervión. The plaque index, PI, and gingival index GI, were registered in the initial exam, al 6, 12, 18 and 24 months. For the test group, the value of the plaque index in the initial exam was 1.57 and for the control group was 1.64. In totally 20 sessions, to the groups test were applied professional monthly clearing, followed by the "aplicación tópica de fluoruro sódico". After 6 months the study began, the plaque index for the group text was 1.18 and for the control group 1.30. In the same way, the gingival index turned out to be 0.21 for the text and 0.37 for the control. The final results gave a plaque index for the text group of 1.01 and for the control group 1.32 and the gingival index 0.29 for the test group and 0.71 for the control. This leads to the thinking that it's enough for children a monthly dental plaque removal, to prevent the develop of the gingivitis.
