This paper aims to identify and analyze the reasons pointed by mothers to prolong breastfeeding beyond the first year of the child s life. The study involved 40 mothers whose children were treated in the Preventive Program of Research and Dental Treatment Center for Special Patients - Dental School of Piracicaba - UNICAMP. The group consisted of mothers who prolonged the breastfeeding beyond the baby s first year of life. All mothers were surveyed by a researcher using a specific questionnaire. In order to avoid information loss, the interviews were taped, then transcripted. Results showed that the main cause of the extended breastfeeding was maternal pleasure. It was also observed that the mother and infant attachment favors prolonged breastfeeding occurrence. Further studies should be carried out for more accurate functional analyses of variable that lead to extend breastfeeding or to wean.

Dental materials that release fluoride have been shown to be effective in caries inhibition around restorations. Adhesive materials would also be effective in caries inhibition by sealing and protecting cavity margins from acidic demineralization. This in vitro study tested the hypothesis that composite restorations with a dentin adhesive system have a caries preventive effect similar to that of an adhesive material with fluoride - glass-ionomer cement - on root surfaces. Twenty roots from extracted sound third molars were embedded in polystyrene resin and ground flat. Standardized cavities were prepared in leveled root surfaces and randomly restored with (a) Chelon-Fil (Espe) or (b) Z100/SingleBond (3M). Baseline indentations were measured at 100, 200 and 300 mum from the occlusal margins of each restoration and the surface microhardness values were obtained using a Knoop diamond indenter. A 2.0 mm wide margin around the restorations was submitted to a pH-cycling model, at 37ºC. After that, surface microhardness was measured again, as it was before. The differences between baseline and final surface microhardness were considered for statistical analysis. The median values of differences were (a): -3.8; -0.3; -1.0; and (b): 3.3; 2.5; 1.7, for the distances of 100, 200 and 300 mum, respectively. The Kruskal-Wallis test did not show statistically significant difference between 100, 200 and 300 mum distances in each tested group. There was no difference between the studied materials at the distances of 200 and 300 mum. Chelon-Fil was statistically different from Z100/SingleBond, at 100 mum (p<0.05). Under the studied conditions, the glass-ionomer cement had a higher caries preventive effect than the composite/dentin adhesive restorations.
