Calculator assisted determination of dilutions for continuous infusion ICU medications.

A program has been developed for simplification of initial dilution calculations for several rapidly metabolized, vasoactive drugs that must be administered by continuous infusion. Included in the program is the capability for serial recalculation of drug dosage or iv flow rate is well as a checking routine to reduce errors. This program was developed primarily for the pediatric age group, where dilution of drugs into a small volume of diluent, accurate dosage calculations, and low iv flow rates are frequently necessary.

Improved adhesion of a glass ionomer cement to dentin and enamel.

A study has been made on improving the adhesion of a glass ionomer cement by the chemical treatment of dentin and enamel surfaces. The most effective surface conditioners were high molecular weight substances containing a multiplicity of functional groups capable of hydrogen bonding. Low molecular weight chelating agents which dissolve calciferous material and dramatically alter the surfaces of enamel and dentin are less effective.

Butt joint versus bevelled gold margin in metalceramic crowns.

The merits of a butt joint versus a bevelled margin are reexamined. It is shown that only acute bevels are effective in reducing the marginal diffusion of plaque acid. However, acute gold bevels may give rise to other major problems in avoiding distortion of the gold during firing of the procelain, and finishing and cementing the crown.

The flow properties of dental cements.

The flow properties of several major types of dental cements were investigated using slow compressive strength and creep techniques. Considerable differences were found in their behavior. Whereas the phosphate-bonded and glass-ionomer cements exhibited brittle fracture, the other cements tended to distort to a greater or lesser extent under load. All cements showed some creep under load but the extent of this varied considerably; the creep of phosphate-bonded cements being very small and that of the eugenol and related cements considerable.
