To extract or not to extract? Management of infraoccluded second primary molars without successors

Restoring coronal contours of retained infraoccluded primary second molars using bonded resin-based composite.

The purpose of this case report is to describe a step-by-step method of restoring function (and esthetics) to infraoccluded second primary molars using a crown-form crown, in a case of bilateral congenital missing premolars. This technique restores form and function, with a minimal reduction to the tooth. It also conserves tooth material and permits good bonding of the resin-based composite to ...

Etiology, Diagnosis, Consequences and Treatment of Infraoccluded Primary Molars

Infraocclusion is a condition where teeth are found with their occlusal surface below the adjacent teeth, long after they should have reached occlusion. Many terms have been used to describe this condition; the most commonly used being submergence and ankylosis. Infraocclusion is classified as slight, moderate or severe. Studies have shown the commonness ratio of infraocclusion in kids being 1....

To use or not to use the force: How B lymphocytes extract surface-tethered antigens

Using an exquisite cell imaging approach based on DNA nanosensors, Spillane and Tolar (2016. J. Cell Biol. https://doi.org/10.1083/jcb.201607064) explore how the physical properties of antigen-presenting cell surfaces affect how B cells internalize surface-tethered antigens. Soft and flexible surfaces promote mechanical force-mediated antigen extraction, whereas stiff surfaces lead to enzyme-me...
