[Microretention of plastic filling materials on acid etched enamel].

In order to study the strength of the physical bond between composite materials and acid etched enamel, various commonly used composites were applied to the conditioned surface of extracted young permanent bicuspids. The specimens were stored in saline at 37 degrees C for one week and nine weeks and then subjected to tensile strength test. The following composites were tested: Restodent, Nuva Seal/Nuva Fil, Cosmic, Smile, Adaptic and Concise Enamel Bond. The latter was used in 4 different ways. The results of the study indicate that all the tested materials have a fairly good retention on the conditioned enamel. However, when using Concise Enamel Bond, care must be taken not to let the pure, liquid resin polymerize on the enamel before applying the composite, because this will give a poor bonding between the enamel and the filling. In addition to the tensile strength test, the materials were submitted to scanning electron microscop, to examine their penetration ability into conditioned enamel. The results of this study seem to indicate that the resin part of viscous composites (Cosmic and Concise pastes) was able to penetrate into the crevices of the etched enamel as well as the more fluid types (Restodent, Nuva Seal and diluted Concise).

Factors influencing whether low-income mothers have a usual source of dental care.

Mothers are both the source of dental caries and the managers of children's use of dental care. This is particularly important for the low-income population. The objective of this research was to explore predictors of having a usual source of dental care among low-income women. Eight-hundred-ten mothers (82 percent white, mean age twenty-seven years), drawn from among participants in an ABCD program in one Washington State County completed a study questionnaire. The study examined predisposing, enabling and illness level variables in relation to whether the mother reported a usual source of dental care for herself. Fifty-two percent of the subjects gave positive answers to the dependent variable Do you now have a dentist you can go to if you have a problem? The analysis suggests that mothers that report good oral health and believe in care for their children are five times as likely to have a usual source of care for themselves than mothers who report both poor oral health and more negative attitudes about dental care for children. The results suggest that interventions aimed at child health that ignore the welfare of the mother are likely to be less successful than those that also address the mothers' needs.
