Oral sedation dentistry Oral sedation dentistry Oral sedation dentistry is a medical procedure involving the administration of oral sedative drugs, generally to facilitate a dental procedure and reduce patients fear and anxiety related to the experience. Oral sedation is one of the available methods of conscious sedation dentistry, along with inhalation sedation (nitrous oxide) and conscious intravenous sedation. Drugs which can be used for sedation include diazepam, triazolam, zaleplon, lorazepam, and hydroxyzine. Dental patients with generalized anxiety, belonephobia (fear of needles and sharp instruments), prior dental trauma, or generalized fear of the dentist can take oral medication in order to reduce their anxieties.
Irrational rotation ergodic transformation, but it is not mixing. The Poincaré map for the dynamical system associated with the Kronecker foliation on a torus with angle is the irrational rotation by . C*-algebras associated with irrational rotations, known as irrational rotation algebras, have been extensively studied. Irrational rotation In the mathematical theory of dynamical systems, an irrational rotation is a map where "θ" is an irrational number. Under the identification of a circle with R/Z, or with the interval [0, 1] with the boundary points glued together, this map becomes a rotation of a circle by a proportion "θ" of a full
