Mineralization disturbances in the deciduous teeth of children with so called minimal brain dysfunction.

Exfoliated deciduous teeth from 14 children with so called Minimal Brain Dysfunction (MBD) and from 14 age-matched comparison children without MBD were collected and ground sections prepared. The sections were analysed by means of polarized light and microradiography. The enamel in ground sections of deciduous teeth from children with MBD showed a wider neonatal line than normal. The prenatal enamel showed a slight tendency to an increase in the degree of porosity, and the overall severe pathology was more common in the MBD group than in the comparison group.

[Quantitative study of the mineral substance of the human dental cementum].

A study of the mineral substance of human dental cementum was made by various biophysical methods. In healthy teeth, average degree of mineralization of the cementum as well as crystallinity and fluoride content of its mineral substance, were found to increase as a function of age. This evolution, typical of the physiological ageing process of calcified tissues, is especially pronounced for the cementum, because of the absence of remodeling activity such as that occuring in bone tissue. Cementum of impacted or semi-impacted teeth was found to have a significantly lower degree of mineralization than that of sound teeth in occlusion. In periodontally diseased teeth, the increase in crystallinity and degree of mineralization of the cementum as a function of age is considerably greater than that observed in healthy teeth. These changes were found to affect the cervical cement first of all, and progressively, the entire tissue. No difference was observed, however, in the fluoride content of the cement of periodontally diseased teeth and healthy teeth of the same age.

What we know and don't know about dietary fluoride supplements--the research basis.

The administration of dietary fluoride supplements has been shown unequivocally to be an effective procedure for preventing dental caries, approaching and sometimes exceeding the benefits generally expected from the consumption of fluoridated water. The latter, however, is far more economical and feasible for benefiting large numbers of children. Prescribing supplements is still recommended for children drinking water with suboptimal amounts of natural fluoride. There is a need to clarify the role of prenatal fluoride administration. As there is uncertainty about the optimal time to initiate fluoride supplementation, the period during which such supplementation should be continued is also unclear. Some studies have addressed the issue, but their findings are equivocal. The decision on when to stop supplementation should be based on the professional judgment of a child's dentist. Combined therapies should be limited to children who are highly susceptible to caries attack. Fluoride supplementation will result in obvious dental fluorosis only if the procedure is misused and reliable dosage schedules have not been formulated; if misused, it is clearly contraindicated in communities with greater than 0.7 ppm fluoride in their water supplies. Used properly and when indicated, dietary fluoride supplementation is a patently safe and highly effective measure for the prevention of dental caries.
