: A thorough understanding of the basic principles of cavity preparation and knowledge of tooth morphology are necessary for the successful positioning of pin channels in the tooth. Sufficient dentin surrounding the channel is necessary for adequate strength, to avoid external fractures of tooth structure and to protect the pulp. Once the channel location is decided upon, it should be made parallel with the external surface of the tooth rather than its long axis. It is suggested that the…

Pins for direct restorations.
TLDR
More research in the area of limiting pin penetration is necessary, as well as attempts to improve the quality control of pin and twist drill manufacture.
In vitro evaluation of dynamic fluid displacement in dentinal tubules activated on pin placement.
TLDR
Investigating the insertion of a self-threading pin when the pinhole was filled with a liquid dye showed that pinholes filled with dye before pin placement had measurable dye displacement.
Penetration of shearing and nonshearing pins into dentin.
An in vitro study was made of the penetration into human dentin of the shearing and nonshearing portions of TMS Minim two-in-one pins when placed manually and mechanically. It was found that the
