International audience; La bronchopneumopathie chronique obstructive (BPCO) est une maladie fréquente que l’on peut prévenir et traiter, qui est caractérisée par des symptômes respiratoires persistants et un trouble ventilatoire obstructif dû à des lésions des voies aériennes (bronchite chronique et/ou du tissu alvéolaire (emphysème), en général en relation avec une exposition significative à des particules ou à des gaz toxiques, selon la définition mise à jour par les recommandations internationales [...]

In the past, especially in the 1970s, tooth mobility has been largely studied by various research groups. Since then, scientific interest in this domain has progressively decreased. However, from a clinical point of view tooth mobility has remained an important concern. This paper aims to review and update basic theoretical notions of tooth mobility after evaluation of recent studies. Finally, clinical implications are discussed.

In the medical literature, and in particular in the field of periodontology, one could observe since several years an increasing interest in diagnostic tests. However, these are often difficult to comprehend. Indeed, understanding the value of these tests implies mastering the meaning of certain basic notions such as sensitivity, specificity and predictive value. The aim of this paper is to present these essential theoretical notions in a simple way and to illustrate them using clinical examples. Finally, several applications of these tests in the field of periodontology will be discussed.

Generally, the principles of tooth preparation are well established in the majority of textbooks dealing with fixed prosthodontics. However, one specific related aspect, retention and resistance form, still features some elements that might be less known to the clinician. The purpose of the present literature review is to contribute to the classification and current understanding of the terms of retention and resistance. Finally, the resulting clinical implications, focusing primarily on cast full veneer and porcelain-fused-to-metal crowns, will be discussed.
