Onset and duration periods of articaine and lidocaine on maxillary infiltration.

Objectives: The aim of this study was to compare the onset and duration of pulpal anesthesia by maxillary infiltration using 2% lidocaine with 1:100,000 epinephrine, 4% articaine with 1:200,000 epinephrine, and 4% articaine with 1:100,000 epinephrine.

Method And Materials: Twenty healthy patients randomly received 1.8 mL of one of the three local anesthetics during operative dentistry procedures of low complexity on three maxillary posterior teeth.

Assessment of cardiovascular parameters during dental procedures under the effect of benzodiazepines: a double blind study.

The purpose of this study was to evaluate cardiovascular parameters during dental procedures: systolic, diastolic, and mean blood pressures, and heart rate. Nineteen healthy normotensive patients (18-56 years of age) received restorative treatment on three maxillary molars. The patients were continuously monitored by a non-invasive automatic monitor for blood pressure and heart rate during the pre-, trans-, and post-operative periods at the following stages: 15 min prior to anesthesia; during topical anesthesia; during infiltrative anesthesia; for 5 minutes immediately after; during cavity preparation; during restorative procedure; for 10 min after completion.

Cardiovascular alterations caused by the administration of 2% mepivacaine HCl with 1:20,000 levonordefrin (Carbocain) in dogs.

We studied possible cardiovascular effects (systolic, diastolic, mean arterial blood pressures, and heart rate) caused by intraoral infiltrative administration of 2% mepivacaine HCl with 1:20,000 levonordefrin in dogs (Canis familiaris), using a Beckman electrophysiograph. Doses used were 0.514 and 1.

Electrolyte concentration in the hypertrophic salivary glands of incisor-amputated rats.

The effect of periodic amputations of the lower incisors of the rat on the electrolyte concentration in the major salivary glands was studied. The incisor amputations caused a hypertrophy of the parotid, submandibular and sublingual glands. The resulting increased weight of the salivary glands was due to a higher dry mass.
