The influence of silicone oil in toothpastes on abrasion in vitro.

The influence of addition of silicone oil to toothpastes was investigated in vitro using a laser reflexion technique and a profilometer. Acrylic plates were subjected to brushing in a brushing machine containing a toothpaste-water slurry. Four different toothpastes were used with and without the addition of 10% silicone oil.

Cleaning effect of toothbrushing with three different toothpastes and water.

The cleaning effect of three different toothpastes and water was studied in vivo using a laser reflexion technique. Ten healthy persons formed the test group. Light reflexion measurements on the upper front teeth were performed before and after the removal of a 72-hour plaque-pellicle.

Surface changes on dental materials. II. The influence of two different dentifrices on surface roughness measured by laser reflexion and profilometer techniques.

Surface changes on eight different dental materials were investigated, using laser reflexion technique and a profilometer. The tested materials were: Acrylic veneers Isosit, Isosit N, K+B+, Multiplus and K+Bpaste Gold Sjödings C Titanium pure non-rolled titanium Ceram a potential ceramic direct filling material The materials were subjected to brushing in a brushing machine, with a toothpaste-water slurry. Two different toothpastes were used separately; Clinomyn and Colgate.

Surface changes on dental materials. The influence of two different dentifrices on surface roughness measured by laser reflexion and profilometer techniques.

Surface changes and wear resistance were investigated on eight different dental materials, using a laser reflexion technique and a profilometer. The tested materials were: (table; see text) The materials were subjected to brushing in a brushing machine, containing a toothpaste-water slurry. Two different toothpastes were used separately; Clinomyn and Colgate.

Dentifrice abrasivity. The use of laser light for determination of the abrasive properties of different silicas. An in vitro study.

The abrasive properties of five different silicon dioxides were investigated using laser reflexion. The substances were milled, amorphous silica gels of which four were commercially available dentifrice ingredients (Syloblanc) and one an experimental product. The abrasion process was carried out on acrylic plates in a brushing machine using two series of slurries of the substances, with and without sodium lauryl sulphate.
