Patients with a history of adverse reactions to a local anesthetic may often be incorrectly labeled as "allergic." Determining if a patient is allergic to a local anesthetic is essential in the selection of appropriate pain control techniques. Local anesthetic allergy testing may be performed safely and with reasonable accuracy by a knowledgeable practitioner. This paper presents guidelines for an allergy testing method.

For people of Chinese descent, facial configuration differs from that of other Asians as well as Caucasians, and the standard nasal masks used in dentistry do not fit their faces well. A simple, easily sterilizable nasal mask has been developed for this purpose and is adaptable to existing nitrous oxide machines.

Effects of nitrous oxide on chloral hydrate sedation of young children.
This study was performed to test the hypothesis that nitrous oxide augments the effects of chloral hydrate sedation of young children. Twenty children with a mean age of 32 months were sedated on two occasions with two different treatment regimens. All subjects received a standard dose of 50 mg/kg of chloral hydrate with or without nitrous oxide during each of two treatment visits. ⋯ During the remainder of the appointment, there was no difference in behavior between the two treatment regimens. Vital signs remained essentially unchanged throughout all treatment with the exception of transitory elevation of the pulse and respiratory rates, which usually occurred when the mouth prop was inserted and local anesthesia was administered. It is concluded that nitrous oxide augments the effect of chloral hydrate sedation of young children, but does not do so uniformly for all children receiving sedation.
