The prevalence of malocclusion and the relationship with oral habits in Brazilian children from two public primary schools was evaluated. The sample was composed of 112 children with mean age of 61 ± 6.67 months. The results demonstrated the presence of malocclusions in 75.8% (n=85). The oral habits was related by 34.8% (n=39). The open bite was the most prevalent malocclusion in the studied population and the oral habits was the decisive etiological factor.

The ectodermal dysplasia constitutes a group of hereditary disorders whose clinical manifestations can be defects in ectodermal structures. The hypohidrotic and anihidrotic are commonly types of ectodermal dysplasia.The main characteristics are dental anomalies, hypotrichosis and hypohidrosis. The oral rehabilitation of this patients is important for better social living, self esteem and oral function. This paper had as objective to relate and discuss a case of anihidrotic ectodermal dysplasia, describing the positive influence of an alternative rehabilitation treatment.

This study aimed to verify the long-term effects of an oral-health-promotion program for 203 schoolchildren 24 months after the interruption of educational activities. They were clinically examined to assess dental plaque and gingival bleeding at baseline, immediately after the educational phase (EP), and 12 and 24 months after withdrawal of the EP. The mean plaque scores gradually increased after interruption of the EP,and in the last assessment they were higher than the baseline scores, but similar to the ones verified 12 months after withdrawal of the EP. The mean gingival bleeding scores were maintained after interruption of the EP. However, it was verified that in the last assessment they were lower than the previous evaluations. And, in all analyses, it was far from the baseline mean scores (P < 0.05). Analysis indicated that the duration of the program favorably influenced its outcome.

The purpose of this study was to implement an Oral Health Promotion Program (OHPP) and check its effectiveness using different indicators at two different times (birth to 10 months after the OHPP). The sample consisted of 325 healthy children (6.1 and 11.3 years old). The results indicated that there was a statistically significant reduction measured by the three indicators (p<0.001). The effectiveness of the OHPP was positive and clearly shown by the oral health indicators used.
