Effect of occlusal treatment on sick leaves in TMJ dysfunction patients with head and neck symptoms.

The aim of the study was to test the effect of occlusal treatment on sick leaves utilized in clinically diagnosed TMJ dysfunction patients who had had sick leaves for head and neck symptoms. The patient population differed clearly from a typical TMJ dysfunction clientele. Qualitative statistical analysis disclosed a significant reduction in sick leaves granted in the treatment group (n = 28). The result was corroborated by quantitative statistical analysis. No change was observed in the control group (n = 25). The changes in the number of days on sick leave and in the signs of dysfunction during the follow-up year showed a tendency to covariation. Since there was little reason to suspect that the placebo effect would have been greater in the treatment group than in the control group, it was concluded that the occlusal treatment could have eliminated some of the causes for sick leaves.

Association between TMJ dysfunction and sick leaves.

Presence of clinically diagnosed TMJ dysfunction and the length of sick leaves were significantly associated in a sample of 599 male Finnish shipyard workers. Neglect of dental health care did not seem to be an explanatory factor, because the amount of untreated caries and the regularity of dental care did not differ significantly between the orthofunction and dysfunction groups. Although the association is no proof for a causal relationship, TMJ dysfunction may explain at least a part of the increase in days on sick leave, because dysfunction was found to be common and at best symptomatically treated in the population studied.

[The reliability of arthrography of the knee joint via medium format technique (author's transl)].

Reports on 217 arthrographies of the knee joint with operative control. Partly or entirely erroneous roentgen diagnoses were made in 4.8-16.3% of the cases, depending upon the technique by which the patients had been examined. Lateral meniscus lesion was wrongly diagnosed three times as often as the medial lesion. The lowest incidence of wrong diagnoses occurred when examining via the medium format technique.

Influence of maternal xylitol consumption on mother-child transmission of mutans streptococci: 6-year follow-up.

Xylitol is effective as a noncariogenic or even cariostatic sugar substitute. Habitual xylitol consumption appears to select for mutans streptococci (MS) which shed easily into saliva from plaque. We have earlier shown that habitual xylitol consumption of mothers was associated with a statistically significant reduction in the probability of mother-child transmission of MS assessed at 2 years of age. The aim of the present study was to assess the children's MS counts 1 and 4 years after the maternal xylitol consumption had been discontinued. At baseline, during pregnancy, all mothers (n = 195) showed high salivary levels of MS. The mothers were randomly assigned to xylitol, fluoride (F) and chlorhexidine (CHX) groups. In the xylitol group, the mothers chewed xylitol-sweetened gum, for 21 months, starting 3 months after delivery. In the two control groups, the mothers received CHX or F varnish treatments at 6, 12 and 18 months after delivery. At the 2-year examination, 169 mother-child pairs participated. At the 3-year and 6-year examinations, there were 159 and 147 children in the study, respectively. For children's MS analyses, visible plaque was collected using toothpicks at the age of 3 and paraffin-stimulated saliva at the age of 6. The persons involved in the collection and analysis of the microbiological samples were blinded as to the study design and group. Both the plaque and salivary MS were cultured on Mitis salivarius agars containing bacitracin. In all groups, the colonization percentages increased during the follow-up. At the 3-year examination, the children's risk of having MS colonization was 2.3-fold in the F group (95% CI 1.3-4.2) compared to the xylitol group. This difference was statistically significant. Even at 6 years of age, the salivary MS levels were significantly lower in the xylitol group than in the other groups (ANOVA, p<0.001). In conclusion, the earlier demonstrated, xylitol-associated reduction in the probability of mother-child transmission of MS was still found in the children's MS counts at the age of 3 and 6 years.
