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.
Proof that e is irrational a proof that "e" is not a root of a second degree polynomial with rational coefficients. This last fact implies that "e" is irrational. His proofs are similar to Fourier's proof of the irrationality of "e". In 1891, Hurwitz explained how it is possible to prove along the same line of ideas that "e" is not a root of a third degree polynomial with rational coefficients. In particular, "e" is irrational. More generally, "e" is irrational for any non-zero rational "q". Proof that e is irrational The number "e" was introduced by Jacob Bernoulli in 1683. More than half a
