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 number then no integral power of it can be an integer, as in lowest terms there must be a prime in the denominator that does not divide into the numerator whatever power each is raised to. Therefore, if an integer is not an exact "k" power of another integer, then that first integer's "k" root is irrational. Perhaps the numbers most easy to prove irrational are certain logarithms. Here is a proof by contradiction that log 3 is irrational. Notice that log 3 ≈ 1.58 > 0. Assume log 3 is rational. For some positive integers "m" and "n", we have
