In the present investigation was studied the relative effect on the gingiva in children of two different kinds of prophylactic measures namely: 1. A single information on the importance of prophylaxis plus mouth rinsings every second week added with distribution of dentifrice every month (rinsing group). 2. A single information on the importance of prophylaxis plus daily supervision of a tooth brushing procedure added with distribution of dentifrice every month (brushing group). A control group received neither information on oral hygiene methods nor participated in any form of supervised or controlled oral hygiene procedures. When the examination of the gingival conditions was performed the experiments had been running for three years. 343 children participated in this investigation and they were at the time for the examination 12‐14 years of age. The gingival state and the oral hygiene were recorded according to index systems proposed by Löe and Silness (1963) and Silness and Löe (1964). The examination revealed: A mean GI value of 0.30 and 0.94 in the brushing and control group. The difference between the groups is statistically significant (p < 0.001). A mean GI value of 0.61 in the rinsing group. Also this score is significantly smaller than that of the control group (p < 0.001). The girls had a lower mean GI than the boys in each of the test groups. The difference was found to be significant in the rinsing group at the 1 per cent level and in the brushing group at the 0.1 per cent level. The prophylactic measures were most effective in the upper front tooth region and least effective in the lower molar region.
