BMC Oral Health 2021 Mar 31;21(1):167. Epub 2021 Mar 31.

Graduate Program in Dentistry, Ibirapuera University, Av. Interlagos 1329, São Paulo, SP, 04661-100, Brazil.

Background: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes.

Methods: A randomized clinical trial with two parallels arms (1:1) will be conducted. Read More

Methods for the Administration of EDAR Pathway Modulators in Mice.

Methods Mol Biol 2021 ;2248:167-183

Department of Biochemistry, University of Lausanne, Epalinges, Switzerland.

Genetic deficiency of ectodysplasin A (EDA) causes X-linked hypohidrotic ectodermal dysplasia, a congenital condition characterized by the absence or abnormal formation of sweat glands, teeth, and several skin appendages. Stimulation of the EDA receptor (EDAR) with agonists in the form of recombinant EDA or anti-EDAR antibodies can compensate for the absence of Eda in a mouse model of Eda deficiency, provided that agonists are administered in a timely manner during fetal development. Here we provide detailed protocols for the administration of EDAR agonists or antagonists, or other proteins, by the intravenous, intraperitoneal, and intra-amniotic routes as well as protocols to collect blood, to visualize sweat gland function, and to prepare skulls in mice.

Simulated dimensional compatibility of uncuffed and cuffed tracheal tubes for selective endobronchial intubation in children.

Paediatr Anaesth 2021 Feb 17;31(2):167-177. Epub 2020 Nov 17.

Department of Anaesthesia, University Children's Hospital Zurich, Zurich, Switzerland.

Background: Cuffed tracheal tubes have recently been recommended for selective endobronchial intubation to establish single-lung ventilation even in smaller children. This implies that, compared with uncuffed tracheal tubes, the cuffed tracheal tubes selected will be smaller and therefore have a shorter length. We hypothesized that cuffed tracheal tubes might be of insufficient length for selective endobronchial intubation if the tube cuff were fully immersed in the left or right mainstem bronchus.

Department of Morphofunctional Sciences I - Pathology, Grigore T. Popa University of Medicine and Pharmacy, Iaşi, Romania;

Although the morphological stages of tooth development, in parallel with maxillary bone construction, are known for decades, the intimate mechanisms of early development of the oral cavity structures and tooth's proper and associated tissues are still incompletely elucidated. Nowadays, the research in embryology was shifted from the morphological to the molecular and genetic approach. This new approach is accomplished by using in vivo and in vitro experimental studies performed on animal models and cell lines. Read More
