Canine reduction can be used to measure hominisation ( BERARD A., PRUDENT N. and all I.A.D.R. 2012). In the phylogenetic classification, the farthest hominoid from Homo is Pongo, then Gorilla and Pan(LECOINTRE,LEGUYADER 2001).Objectives: The aim of this study was to test the field of validity of canine reduction comparatively with the phylogenetic...

We estimated the international spreading of the knowledge produced by French dental master theses by searching for corresponding publications, either as articles in Medline-indexed journals or abstracts of IADR meetings published in the Journal of Dental Research. From the 634 theses defended in 2010 in the 16 French odontology faculties, we found...

Les marges de « l'esthétique dentaire » que l'analyse en termes de design révèle, s'enracinent dans la réflexion sur la création comme soit une mimétique instituée, soit une institutionnalisation des différences. Elles définissent les rôles du praticien, de l'artisan, du designer. Elles soulignent l'importance d'une réflexion axiologique sur leur p...

In the phylogenetic classification, the farthest hominoid from Homo is Pongo, then Gorilla and Pan (LECOINTRE, LEGUYADER 2001). Objectives: , the aim of this study was to measure a criterion of hominisation: canine reduction. Methods: , the mesio distal diameter of canine and lateral incisor was measured with a calliper rule (1/20è mm) on 30 mandib...

Le terme de pédagogie est resté trop longtemps fidèle à son étymologie et son usage moderne a contribué à entretenir l’idée que la formation consistait à établir un rapport quasi mécanique (et donc réglage) entre théorie et pratique, entre une technique et son usage, bref entre savoirs et compétences. Rien n’est moins sûr. Le professeur explique, m...

the polymerisation contraction of resin-based composites (RBCs) used for coronary filling is a central problem in odontology. Here we present a new Silorane-based composite (SBC) with oxirane monomers and siloxane. Using ring-opening oxirane monomer causes less polymerisation contraction1. It is well known that the mechanical properties of the RBCs...
