The aim of the study is to evaluate and compare the periodontal health condition in children and teenagers by means of some periodontal clinical indices. Material and method: The study, developed over 3 years (2007- 2009), was performed on 134 children and teenagers, divided into 3 groups, according to age. Periodontal scanning in the children and teenagers under investigation appeared as a simple and rapid method for the identification of the periodontal problems, easily tolerated by the patients, providing indications on the possible treatament or subsequent evaluation. Results and discussion: Out of the total number of cases, only 22.09% had periodontal symptoms, the highest value being represented by generalized bacterial gingivitis (63 cases-57.78%), followed by chronic surface marginal periodontitis, caused by some local inflammation factors (21.39%), and by aggressive forms of periodontal disease (such as aggressive periodontitis), in a ratio of 7.83% (7 cases), comparatively with a ratio of 1%, mentioned in the literature of the field. No cases of deep periodontal disease (chronic average/deep marginal periodontitis) were recorded, as they need a long time for their installation and evolution.
Conclusions: children show a more important accumulation of bacterial plaque than adults, and numerous slight gingival inflammations. In children with ages betwen 12-17 years and in young adults, the gingival reaction is more important in the presence of a higher accumulation of bacterial plaque.
