Abstract

The aim of this study was to assess the need and demand for sedation or general anesthesia (GA) for dentistry in the Canadian adult population. A national telephone survey of 1101 Canadians found that 9.8% were somewhat afraid of dental treatment, with another 5.5% having a high level of fear. Fear or anxiety was the reason why 7.6% had ever missed, cancelled, or avoided a dental appointment. Of those with high fear, 49.2% had avoided a dental appointment at some point because of fear or anxiety as opposed to only 5.2% from the no or low fear group. Regarding demand, 12.4% were definitely interested in sedation or GA for their dentistry and 42.3% were interested depending on cost. Of those with high fear, 31.1% were definitely interested, with 54.1% interested depending on cost. In a hypothetical situation where endodontics was required because of a severe toothache, 12.7% reported high fear. This decreased to 5.4% if sedation or GA were available. For this procedure, 20.4% were definitely interested in sedation or GA, and another 46.1% were interested depending on cost. The prevalence of, and preference for, sedation or GA was assessed for specific dental procedures. The proportion of the population with a preference for sedation or GA was 7.2% for cleaning, 18% for fillings or crowns, 54.7% for endodontics, 68.2% for periodontal surgery, and 46.5% for extraction. For each procedure, the proportion expressing a preference for sedation or GA was significantly greater than the proportion having received treatment with sedation or GA (P < 0.001). In conclusion, this study demonstrates that there is significant need and demand for sedation and GA in the Canadian adult population.

Abstract

Progressive muscular dystrophy may produce abnormal reactions to several drugs. There is no consensus of opinion regarding the continuous infusion of propofol in patients with progressive muscular dystrophy. We successfully treated 2 patients with progressive muscular dystrophy who were anesthetized with a continuous infusion of propofol. In case 1, a 19-year-old, 59-kg man with Becker muscular dystrophy and mental retardation was scheduled for dental treatment under general anesthesia. General anesthesia was maintained by a continuous infusion of 6–10 mg/kg propofol per hour and an inhalational mixture of 67% nitrous oxide and 33% oxygen. No complications were observed during or after the operation. In case 2, a 5-year-old, 11-kg boy with Fukuyama type congenital muscular dystrophy and slight mental retardation was scheduled for dental treatment under general anesthesia. General anesthesia was maintained with a continuous infusion of 6–12 mg/kg propofol per hour and an inhalational mixture of 0.5–1.5% sevoflurane in 67% nitrous oxide and 33% oxygen. No complications were observed during or after the operation. It is speculated that a continuous infusion of propofol in progressive muscular dystrophy does not cause malignant hyperthermia because serum levels of creatine phosphokinase and myoglobin decreased after our anesthetic management. Furthermore, our observations suggest that sevoflurane may have some advantages in patients with progressive type muscular dystrophies other than Duchenne muscular dystrophy and Becker muscular dystrophy. In conclusion, our cases suggest that a continuous infusion of propofol for the patients with progressive muscular dystrophy is a safe component of our anesthetic strategy.

Abstract

A rare and unusual case of hallucinations following triazolam administration is reported. A review of the literature suggests that hallucinations following triazolam are rare; this is the first report of such a reaction when triazolam was used for oral conscious sedation in dentistry. A discussion of dental implications follows with emphasis on complete medical history evaluation before administering oral sedatives. We conclude that the proper selection of oral sedation candidates, coupled with recognition and management of adverse events, is essential.
