Drooling is a common and incapacitating problem in Parkinson's disease (PD). Treatment with botulinum neurotoxin (BoNT) into the parotid glands seems beneficial. Injection of the submandibular glands may also be effective since these produce 70% of the daily unstimulated saliva. We randomly allocated patients to BoNT injections into the submandibular glands(More)
An ion-sensitive field effect transistor (ISFET, Sentron, Sentron, Inc.) electrode was compared with a glass combination micro-electrode (MI-410, Micro-electrodes, Inc.) and a solid-state metal wire oxide pH sensor (Beetrode, World Precision Instruments, Inc.) with a liquid junction reference electrode (MERE1, World Precision Instruments, Inc.). The(More)
The plaque acidogenic response of children from three ethnic groups in South Africa to four different carbohydrates was investigated using the plaque sampling method. A total of 30, 12-year-old children, ten black, ten 'coloured' and ten white, completed this study. The foods tested were 10 per cent sucrose solution, maize porridge, strawberry flavoured(More)
A portable glucometer method was used to measure clearance of salivary glucose in 31 black and in 28 white 12-year-old school children. The aims of this study were to evaluate a readily available portable glucometer method and to investigate salivary glucose clearance as a marker of caries risk. Following the initial evaluation, we adapted the portable(More)
This study was undertaken to establish whether the quantitation of dental plaque protein by a dye-binding method (Coomassie G-250) may be used as an index of the amount of dental plaque sampled. Ten sites were sampled in 34 children on 5 occasions at 4 month intervals. The mean protein concentration in 1391 plaque samples was 6.9 +/- 4.1 micrograms(More)
