Endodontic files and reamers are surgical instruments used by dentists when performing root canal treatment. These tools are used to clean and shape the root canal, with the concept being to perform complete chemomechanical debridement of the root canal to the length of the apical foramen. Preparing the canal in this way facilitates the ...
Examples of this are undercuts, slots/grooves or root canal posts. In some cases this may necessitate excessive amounts of healthy tooth structure to be removed. Hence, alternative resin-based or glass-ionomer cement-based materials are used instead for smaller restorations including pit and small fissure caries.
All-in-one self-etch adhesive and a single component universal adhesive, used in the adhesion of direct and indirect dental restorations.

You can propagate monstera cuttings in water or soil, but soil is recommended. The cuttings are more susceptible to developing root rot or mushy stems when placed in water. Read the original ...
Chemically cured resin composite is a two-paste system (base and catalyst) which starts to set when the base and the catalyst are mixed together. Light cured resin composites contains a photo-initiator (e.g. camphorquinone) and an accelerator. The activator present in light activated composite is diethyl-amino-ethyl-methacrylate (amine) or ...
The post on the left is a tapered post, the one on the right is a parallel post. In post and core fabrication, it is desirable that the post descend at least two-thirds of the length of root canal (or not less than the height of the crown) in order to provide sufficient retention.
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A ...
How to Propagate from Cuttings. Some plants, like begonias, will readily grow roots from a leaf cutting. Ferns, however, will not. There are a few fern species, though, that can grow plantlets ...
