[Scanning electron microscopic studies on the efficacy of irrigated, hand root canal preparation].

The effectiveness of hand preparation and irrigation of 48 root canals of upper anterior teeth was evaluated by scanning electron microscopy. Independently of instrument (K reamer or combination K reamer and H file), irrigating solution (sodium chloride) and root canal dressing a similar degree of preparing and cleaning effectiveness of root canals was detected. In all groups a homogeneous or inhomogeneous smear layer of different thickness and extent dominated. A scale of preparing and cleaning effectiveness is recommended.

[Transparent dentinal sclerosis and its clinical significance].

Localisation, extension, age dependence and permeability of the translucent zones in different progression stages of the dentine caries were examined by light microscopy, histochemical methods and dye penetration on ground sections, thin-ground sections and decalcified material of extracted human teeth. This phenomenon is observed in every age and more interpreted as a passive chemical precipitation than a protective activity of the pulp-dentine-system. As it is developed incompletely, it represents at most a relative, but not a proof protection from penetrating noxious actions.

Electroconvulsive therapy and intracranial aneurysm. Prevention of blood pressure elevation in a normotensive patient by hydralazine and propranolol.

A 42-year-old normotensive woman developed a severe mental depression 6 months after an operation for intracranial aneurysm. The use of electroconvulsive therapy (ECT) was judged to be of vital importance. By concurrent administration of intravenous hydralazine and propranolol before induction of anaesthesia the normally occurring ECT-induced blood pressure elevation was completely prevented, and the patient received a series of ten ECTs without complications.
