NT-proBNP and troponin T are useful in excluding AECOPD associated with left ventricular dysfunction. NT-proBNP was the more accurate of the two.

Rehabilitation of endodontically treated molar still remains a challenge. After endodontic treatment, molars lost their mechanical characteristics. In fact, they became fragile and that is in relation with the removal of pulp and surrounding dentin tissues. Endocrown which is a single partial restoration could be considered as a good alternative for restoring molars having large coronal destruction and presenting endodontic treatment difficulties. Through this work, we discuss the indication and use of endocrown to replace single crowns with intraradicular retention and to present a clinical case report of an endocrown-type restoration, fabricated from lithium disilicate ceramic (IPS e.Max CAD) in a mandibular first molar with extensive coronal destruction.

Objectives To evaluate the effect of orthodontic appliances on physicochemical, biochemical, and oxidative stress changes in salivary parameters during treatment. Materials and Methods A cohort study was conducted with 112 healthy patients. Salivary samples were taken at baseline, 1 month, and 9 months after placement of the orthodontic appliances used in treatment. Results A statistically significant difference was observed in certain examined salivary parameters, including enzymes, electrolytes, and oxidative stress markers. Conclusions The use of aligners had a lower prevalence of disturbing salivary parameters. Orthodontist must consider these changes to prevent the occurrence of white spot lesions.

Introduction : L’ingression dentaire est depuis longtemps considérée comme l’un des mouvements les plus difficiles à réaliser en orthodontie. La principale difficulté rencontrée est, avec un traitement par mécaniques conventionnelles, la maîtrise d’ancrage, si délicate à assurer pour éviter des mouvements parasites presque certains. Les mini-vis émergent dans ce cadre comme un moyen d’ancrage très efficace, facilitant et simplifiant le mouvement d’ingression des dents, aussi bien antérieures que postérieures, sur le plan biomécanique, offrant à l’orthodontiste de nouvelles perspectives thérapeutiques. Objectif : L’objectif de notre travail est de décrire l’utilisation des mini-vis sur le plan clinique et biomécanique dans le cadre de l’ingression dentaire.
