Comparative study on metal versus zirconium dioxide infrastructure manufacturing in prosthetic rehabilitation in the maxillary frontal zone
Prosthetic rehabilitation of the maxillary front teeth is an extremely laborious problem for the dental team, consisting of the dentist and the dental technician. If for the physiognomic component the most recommended materials are the ceramic masses, for the resistance substrate there are several variants. Conventional technologies using dental alloys and modern ones involving the use of zirconium dioxide can be used successfully in performing fixed prosthetic restorations in the maxillary frontal area, both options having both advantages and disadvantages, as we will describe in this material
Dentists, members of the French Resistance movement during the World War II
The Resistance was a reaffirmation of France's independence and individuality, as well as a struggle to regain freedom and, above all, national integrity. In fact, many historians appreciate that the French Resistance could have achieved more if it had been more effectively integrated into Allied plans and strategies. Thus, in this material we tried to present some short biographies of dentists who worked in the French Resistance against the German occupation troops, some of them even paying with their lives for the courage they showed
Sexual dimorphism of crania in a Romanian population: Discriminant function analysis approach for sex estimation
Abstract: Regarding sex estimation on human skeletal remains, the current trend in forensic anthropology is towards creating national standards, as population-specificity of discriminant functions is now a known fact. Also, over the last period of time, discriminant function analysis of osteometric data has become the method of choice in forensic anthropology, as it renders high accuracy results, superior to those obtained by visual shape assessment or direct metric comparison. We have conducted a study on 200 adult crania (100 males, 100 females) from a modern Romanian population sample (Rainer collection, Bucharest). Based on 11 cranial measurements, we have calculated population-specific discriminant functions for intact crania, cranial vault and facial region measurements, as well as single-variable DF. The results point to a pronounced craniometric sexual dimorphism in Romanian population, similar to other European populations: sexing accuracies of 88% on intact crania, 81% on cranial vault measurements and 83.5% on facial measurements respectively, with 83.5% correctly assigned by facial breadth alone discriminant function. Discussions on the results, as well as comparisons with similar studies are presented below. Key Words: sex estimation, discriminant function, romanian population, cranial measurements, fragmented crania. D iscriminant function analysis for sex estimation on human skeletal remains has become a method of choice over the last period of time, as many researchers have studied its usefulness all over the world 1) "Carol Considering the above, we have conducted a study on a series of Romanian skulls, in order to assess the sexual dimorphism of Romanian population, compared to other European and worldwide populations. In this article we present only the results for cranial measurements, as we have already communicated the results from the mandible measurements within the previous journal issu
