[Conservative treatment of deciduous teeth--a review].

In all countries with a lack of manpower in dentistry, there is an unfortunate tendency to leave the primary teeth without proper conservative treatment. In addition to toothaches and poor esthetics, a neglected care of the primary dentition may result in several other untoward effects. Decayed deciduous teeth may cause such a discomfort during tooth-brushing that the child is prevented from learning good oral hygiene habits. With bad primary molars the child cannot chew properly, and may have to choose soft and often cariogenic food. When the permanent teeth erupt among the decayed deciduous teeth, there will be a greater chance for them to have carious attacks as well. Premature loss of primary molars may lead to malocclusion. It must also be kept in mind that the treatment of badly decayed teeth, including necessary extractions, may be difficult. This may cause fear of dental treatment. On the basis of current Swedish philosophies of treatment the author surveys various conservative procedures for deciduous teeth-amalgam therapy, stainless steel crowns, composites and disking.

Cinnamic aldehyde in toothpaste. 1. Clinical aspects and patch tests.

Although cinnamon is known to cause dermatitis in bakers and confectioners, it has only rarely been reported as causing trouble in food or cosmetics. A newly-formulated 'spicy' toothpaste containing cinnamon as a flavouring agent was the cause of oral symptoms in eight patients referred to clinics in Buckinghamshire and in Malmö and in a further eight patients discovered subsequently. Similar symptoms and patch test results were observed independently at both centres. Positive reactions were obtained with 1% cinnamic aldehyde in 15 out of 16 patients tested. Only one patient reacted to a standard sample of balsam of Peru (25% in petrolatum).

Lauryl ether sulphate dermatitis in Denmark.

Lauryl ether sulphate (LES), a synthetic detergent, may sometimes contain an allergenic impurity, which has given rise to several outbreaks of contact dermatitis. Such an outbreak occurred in Denmark in 1971. All cases diagnosed were confined to one household, while other cases may have passed unnoticed.

Iron absorption during iron supplementation in blood donors.

The total amount of iron absorbed from a total supplementation of 2000 mg of iron was studied after a blood donation. 10 regular blood donors and 10 subjects without previous blood loss were included in the study. No subject had received any iron treatment before the investigation. Both groups were given one sustained release tablet containing 100 mg of iron as Fe SO4 once daily for 20 days. The iron in these tablets was labelled with 59Fe. The total amount of iron absorbed from the tablets was measured by a whole body counting technique. Laboratory tests including haematological data, desferrioxamine tests and sternal marrow punctures were made before and after the iron treatment. The non-donors lost a mean amount of 215 mg iron by phlebotomy and the total iron absorption from the tablets was only 94 mg (4.7%). In the regular blood donors the corresponding iron loss was 276 mg and the absorption was 280 mg (14%). The iron supplementation given in this study covered the iron losses in the regular blood donors but not in the non-donors. This iron prophylaxis will present a depletion but not a reduction of the iron stores in blood donors with high donation frequency.

Acetylsalicylic acid and gastrointestinal bleeding measurement of blood loss using a modified radioactive chromium method.

A comparative study of the gastrointestinal blood loss during intake of a new buffered acetylsalicylic acid (ASA) preparation and plain ASA tablets has been performed. A modified radioactive chromium method was used. The 51Cr activity was considerably less than that used in previous methods, and no feces homogenization was necessary. The study was performed in 18 volunteers using a randomized crossover design. A significant reduction in gastrointestinal bleeding was registered during ingestion of the buffered ASA in comparison with the plain ASA tablets.

Allergenicity of epoxy-reactive diluents in the guinea pig.

The sensitizer in epoxy resins may be the actual resin, the hardeners, the reactive diluents or the additives. An epoxy-reactive diluent, Epoxide No. 8, recently introduced on the Swedish market, and described by the manufacturer as nonsensitizing was checked for allergenicity by "the guinea pig maximization test". Judging from the results, Epoxide No. 8 in the guinea pig test was even more allergenic than butylglycidyl ether, another reactive diluent known to be a human skin sensitizer. The potential allergenicity of Epoxide No. 8 was also indicated by the fact that butylglycidyl ether, cresylglycidyl ether and epoxy resin elicitated positive reactions in animals sensitized to Epoxide No. 8.
