Conservative esthetic management of severe dental fluorosis with in-office power bleaching.

Abstract Fluorosis is an endemic disease, prevailing in about 25 countries globally. Dental fluorosis is an acquired defect of enamel due to the exposure of an individual to excessive fluoride levels during tooth development. It could result in mild-to-severe discoloration of teeth, which might necessitate esthetic correction. Bleaching is one of the common treatment modalities used in the esthetic correction of such cases. In-office power bleaching is one of the techniques of tooth bleaching t

Serum fluoride levels following commencement of methoxyflurane for patient analgesia in an ambulance service.

Editor—Methoxyflurane, once a frequently used anaesthetic agent,1 is re-emerging as an inhalation analgesic. In modern practice, it is given in doses of up to 6 mL via a proprietary patient-controlled self-delivery device2  with an activated carbon filter designed to adsorb some methoxyflurane vapour from the patient's exhaled breath.3 Methoxyflurane is an organic vapour, identified as causing local environmental contamination when administered in anaesthesia or analgesia, and can subseque
