[Overdentures covering natural roots. The use of chlorhexidine gel]. / Overkappingsprothesen op natuurlijke pijlers. Het gebruik van chloorhexidinegel.

To prevent caries and periodontal disease in overdenture abutment teeth, daily application of chlorhexidine gel is recommended. In order to get insight into the use of the gel, 29 overdenture wearing patients were interviewed. In addition the patients were requested to show the use of the gel. It was concluded that at any time the patients were instructed about the use of the gel. Nevertheless, a majority of the patients did not use the gel daily and in accordance with the instructions given. Application of the gel in the abutment depressions of the overdenture appeared to be a heavy task.

Seizure following brief exposure to the insect repellent N,N-diethyl-m-toluamide.

A 5-year-old boy with a history of mild developmental delay experienced a major motor seizure at day camp after topical application that morning of the insect repellent Muskol and a later application of OFF [both contain N,N-Diethyl-m-toluamide (DEET)]. The patient continued convulsing in the emergency department and was treated with diazepam. Laboratory tests were unremarkable, as were lumbar puncture, computed tomography scan, and blood cultures. Skin decontamination was performed. DEET levels in the urine were 0.003 micrograms/mL. Although seizures and encephalopathic syndrome have been described with DEET in previous case reports involving topical exposure of pediatric patients, atypical aspects with regard to this case include that this patient was a male (most other case reports involve females), exposure was relatively brief compared with other reports, and the patient developed seizures without a prodrome described in previous reports. Avoidance of high-concentration DEET formulations in pediatric patients should be considered.
