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 between 2 and 3: We then analyze a blown-up difference "x" of the series representing "e" and its strictly smaller partial sum, which approximates the limiting value "e". By choosing the magnifying factor to be the factorial of "b", the fraction ⁄ and the partial sum are turned into integers, hence "x" must be a positive integer. However, the fast convergence of the series representation implies that the magnified approximation error "x" is still strictly smaller than 1. From this contradiction we deduce that "e" is irrational. Suppose that "e" is a rational number. Then there exist positive integers "a"
