Epidemiological study regarding the frequency of the "white spot" lesion
The preventive programmes applied to the young people have to be based on epidemiological studies in
which the pre-cavitated lesion must be included.
The aim of the study is to evaluate the frequency of the "white spot" lesions in a large group of children
from Constanta, aged between 8 and 13 years.
Material and methods: the study was conducted on 1024 children. As diagnostic methods was used: the
clinical exam associated with a dye as a guide for the sub-surface lesions, the bitewing radiographical
exam and the measurement of the laser-induced fluorescence of the enamel by using the Diagnodent
Results: 16.82% from the examined surfaces have pre-cavitated lesions and all the occlusal and approximal
surfaces of the lateral teeth are susceptible at caries in the first years after eruption of the teeth.
Conclusion: much more attention has to be directed to the early identification and conservative treatment
of the pre-cavitated lesions of the enamel.
Key words: early diagnosis, white spot, pre-cavitated lesion, preventive programmes, conservative therapy.
