Data were analysed using the Spearman’s correlation, Wilcoxon signed rank, and Mann–Whitney U-test. Results.  Except group IV, there was a statistically significant decrease in fluorescence after the application of sealants (P < 0.05). The decrease of LFpen readings in the opaque sealant groups was more significant than the clear

sealant groups (P < 0.05). But for both sealants, the difference between phosphoric acid and Clearfil S3 Bond groups was nonsignificant (P > 0.05). Conclusions.  There was a statistically significant decrease in fluorescence for both clear and opaque sealant groups. However, clear sealant with Clearfil S3 Bond does not influence the LFpen readings. “
“Generalized aggressive periodontitis (GAP) is a multifactorial disease that shows a specific microbial profile and a familial see more aggregation. This study evaluated the salivary microbial

profile of families with a history of GAP and compared them with healthy families. Fifteen families with parents presenting periodontal health and 15 with parents with a history of GAP were selected. Each family had a child aged 6–12 years. Stimulated saliva was collected from all subjects, and Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), and Aggregatibacter actinomycetemcomitans (Aa) amounts were determined. Children of GAP families showed higher detection of Aa (90%) learn more than children of healthy families (45%) (P < 0.05). Parents with GAP showed a Pg salivary concentration statistically higher than that of healthy parents (P < 0.05).Children of GAP families, however, exhibited similar Pg concentration than healthy children (P > 0.05). Tf amounts did not differ either in parents or in children (P > 0.05) The infection risk calculation indicates that children who have one parent who is positive for Aa have 16.3 times (95% CI 3.1–87.2) more risk of being infected with Aa (P < 0.05) than children from an Aa-negative enough family. It may be concluded that children

of parents with aggressive periodontitis have higher levels and higher risk of Aa infection. “
“Background.  With increasing survival rates for childhood cancer, late effects are of growing importance. Oral health is central to general health, level of nutrition, quality of life, and is significant in the holistic care of children during cancer therapy. Hypothesis.  The oral health needs of children treated for solid tumours/lymphoma will be greater than the general population, groups will differ according to tumour and treatment. Design.  One hundred and twenty patients, 0–17 years, under follow-up from 01/07/06 to 07/02/07 were investigated for caries, opacities, microdontia, and gingivitis. Analysis was performed with stratification according to tumour and treatment. Comparisons made with the UK 2003 Child Dental Health Survey. Results.
