Einfluss der Retention auf die Weisheitszahnmineralisation

Zusammenfassung: In der zahnärztlichen Altersdiagnostik ist die radiologische Beurteilung der Weisheitszähne das wichtigste Kriterium bei der Frage nach der Vollendung des 18.Altersjahres. Als alleiniges Kriterium geben die Weisheitszähne auch bei abgeschlossenem Wurzelwachstum diesbezüglich keine rechtsgenügende Sicherheit. In der vorgestellten Arbeit wurde untersucht, ob bei retinierten Weisheitszähnen im Unterkiefer das Wurzelwachstum verzögert wird und damit die Wahrscheinlichkeit für ein vollendetes 18.Lebensjahr steigt. Es konnte mithilfe der logistischen Regression gezeigt werden, dass, verglichen mit den Fällen durchgebrochener dritter Molaren, bei retinierten Weisheitszähnen mit abgeschlossenem Wurzelwachstum eine Verzögerung von 0,6Jahren bei männlichen und 0,7Jahren bei weiblichen Untersuchten auftritt. Es konnte kein einziger Proband mit retinierten unteren Weisheitszähnen und abgeschlossenem Wurzelwachstum beidseits identifiziert werden, der jünger als 18Jahre war. Bei Vorliegen eines retinierten dritten Molaren mit abgeschlossenem Wurzelwachstum nur auf einer Seite konnte ein einzelner Explorand von unter 18Jahren festgestellt werden (17Jahre, 11 Monate!). Fazit: Können bei der zahnärztlichen Altersdiagnostik 2 retinierte Weisheitszähne mit abgeschlossenem Wurzelwachstum im Unterkiefer festgestellt werden, darf bei Mitteleuropäern ein Mindestalter von 18Jahren mit an Sicherheit grenzender Wahrscheinlichkeit angenommen werden. Ist ein retinierter Unterkieferweisheitszahn mit abgeschlossenem Wurzelwachstum vorhanden, ist das 18.Lebensjahr mit sehr großer Wahrscheinlichkeit vollende

Einfluss der Retention auf die Weisheitszahnmineralisation

In dental age diagnostics radiological evaluation of third molars is the most important criterion to establish whether an individual has attained 18 years of age. However, completed root development of third molars as the only criterion is insufficient for an establishment of legal certainty. In the present paper it was investigated whether root development is slowed down in impacted lower third molars and thereby increases the probability that 18 years of age has been attained. By means of logistic regression a delay of 0.6 years in male subjects and 0.7 years in female subjects was shown in impacted third molars with completed root development compared to cases with erupted third molars. There was no case in which an individual with impacted lower third molars with completed root development on both sides was under the age of 18. In the presence of impacted third molars with completed root development on one side only one subject was under 18 years of age (17 years and 11 months!). Conclusion: If two impacted third molars with completed root development in the lower jaw are determined in dental age diagnostics, a minimum age of 18 years in central Europeans can be suspected beyond any reasonable doubt. If one impacted mandibular third molar with completed root development is present it is very likely that 18 years of age have been attained

Global Asset Allocation Shifts

We show that global asset reallocations of U.S. fund investors obey a strong factor structure, with two factors accounting for more than 90% of the overall variation. The first factor captures switches between U.S. bonds and equities. The second reflects reallocations from U.S. to international assets. Portfolio allocations respond to U.S. monetary policy, most prominently around FOMC events when institutional investors reallocate from basically all other asset classes to U.S. equities. Reallocations of both retail and institutional investors show return-chasing behavior. Institutional investors tend to reallocate toward riskier, high-yield fixed income segments, consistent with a search for yield

Dental age diagnostics by means of radiographical evaluation of the growth stages of lower wisdom teeth

The main criterion for dental age estimation in living adolescents and young adults is mineralization of third molars. A total of 1,260 orthopantomograms of 669 female and 591 male subjects aged between 15 and 22years was examined. Of the orthopantomograms, 1,137 were from patients with Swiss citizenship and 123 were from other European countries. The mineralization status of lower third molars was evaluated based on Demirjian's classification of stages. For the statistical assessment of data, logistic regression and mean value testing were used. The findings show that completed growth in wisdom teeth is observable at ages less than 18. Male individuals were approximately 1year ahead of females at stage H, and South East Europeans were approximately 6months ahead of Swiss (Central Europe) at stage H. Mean values led to false conclusions regarding the question of the attained age of 18. Therefore, regression analysis should be used for the statistical assessment of data in dental age diagnostic

From Deutsche Zeitschrift to International Journal of Legal Medicine-100 years of legal medicine through the lens of journal articles : Part 3: Zeitschrift für Rechtsmedizin-Journal of Legal Medicine from 1970 to 1990.

From volume 67 (1970) onwards, the journal appeared under the new bilingual title Zeitschrift für Rechtsmedizin-Journal of Legal Medicine. The editorial board was expanded and internationalised. From 1970 to 1990, 1416 articles were published in 36 volumes. 1036 articles were in German and 380 in English. The authors of 411 articles came from non-German-speaking countries. Compared to the periods under review in the first two parts of our article series, the proportion of papers on forensic genetics increased significantly between 1970 and 1990, with a small increase in publications on the identification of unknown dead bodies. An opposite trend was observed in the articles on forensic psychiatry and psychology, sexual medicine and social medicine. This development reflects a further sharpening of the discipline's profile

Variables affecting the probability of complete fusion of the medial clavicular epiphysis

In this study, we have combined data on clavicle fusion from different studies and applied a binomial logistic regression analysis. As such, we aimed to assess whether or not variables such as sex, socioeconomic status, and ethnicity influence the probability of having mature, i.e., completely fused clavicles at a given age. We further explored whether the method of clavicle examination, i.e., diagnosis from either a dry bone specimen, an examination of X-rays, or an examination of computed tomography scans, affects the probability of being diagnosed with mature clavicles. It appeared that only ethnicity did not significantly affect this probability. Finally, we illustrated how the logit model may be used to predict the probability of being diagnosed with mature clavicles

Currency value

We assess the properties of currency value strategies based on real exchange rates. We find that real exchange rates have predictive power for the cross-section of currency excess returns. However, adjusting real exchange rates for key country-specific fundamentals (productivity, the quality of export goods, net foreign assets, and output gaps) better isolates information related to the currency risk premium. In turn, the resultant measure of currency value displays considerably stronger predictive power for currency excess returns. Finally, the predictive information content in our currency value measure is distinct from that embedded in popular currency strategies, such as carry and momentum

From Deutsche Zeitschrift to International Journal of Legal Medicine-100 years of legal medicine through the lens of journal articles : Part 2: Deutsche Zeitschrift für die gesamte gerichtliche Medizin from 1948 to 1969.

The interruption of the publication of the Deutsche Zeitschrift für die gesamte gerichtliche Medizin due to the war ended with volume 39 for the years 1948/1949. Until volume 66/1969, the journal appeared unchanged under the historical title. The 912 publications contained in the 28 volumes of these two decades cover topics from the main fields of forensic medicine, but also from related and unrelated disciplines. The topic-specific analysis of the publications shows a shift of the research focus in the German institutes since the post-war period. This is most evident in the decline in the number of publications from the fields of scientific and technical criminalistics as well as forensic psychiatry and psychology. An opposite trend with a significant increase in scientific papers was observed in alcohology, forensic genetics and traffic medicine. While the evaluated publications on most topics contain new findings that are still valid today, the use of blood group characteristics for forensic purposes came to an end as a result of the introduction of DNA analysis

Invariant sets for discontinuous parabolic area-preserving torus maps

We analyze a class of piecewise linear parabolic maps on the torus, namely those obtained by considering a linear map with double eigenvalue one and taking modulo one in each component. We show that within this two parameter family of maps, the set of noninvertible maps is open and dense. For cases where the entries in the matrix are rational we show that the maximal invariant set has positive Lebesgue measure and we give bounds on the measure. For several examples we find expressions for the measure of the invariant set but we leave open the question as to whether there are parameters for which this measure is zero.Comment: 19 pages in Latex (with epsfig,amssymb,graphics) with 5 figures in eps; revised version: section 2 rewritten, new example and picture adde
