AIM: This study aims to analyse the results of a questionnaire submitted to students of the elementary schools in L'Aquila in order to understand their awareness of a correct caries prevention method by using fluoride. MATERIALS AND METHODS: 4th and 5th grade students of elementary schools in L'Aquila were submitted to a questionnaire; from a total of 1205 students, age ranging from 8 to 12, 1094 were questioned; 7 children 8 years old, 282 of 9, 555 of 10, 243 of 11, 8 of 12, and only 2 of 13, respectively (the last 2 were registered later at school because non-EU citizens). RESULTS: Among the Italian population with a low incidence of dental decay, a relatively limited group, called 'high risk decay group', revealed a higher incidence of the pathology than the standard one. CONCLUSION: In a multiracial society, as ours, it is important to carry out an effective screening in order to recognize different categories of patients through simple questions inserted in the patient's case history.

Multiple and relapsing supernumerary teeth associated to dens invaginatus. Review of the literature and case report.

The aim of this paper is to show problems related to supernumerary teeth therapy according to their formation and mineralization. The clinical case of an 11-year old boy suffering from alteration of the eruptive sequence of the upper incisor teeth caused by 2 supernumerary teeth in the premaxilla, is reported. What is interesting about this case is that after the surgical removal of the supernumerary teeth, with a radiographic examination taken 6 months later, 2 other supernumerary teeth were observed. The authors point out that while the clinical approach can be the same for different situations it is not possible to have the same approach for the surgical therapy which may be different from case to case.
