Cracks at the weld location between the engine cradle and brackets were observed in all the vehicles at an average distance of 10,000 km.
The models of Davison et al. and MINTEQA2, based upon amorphous FeS solid phases, bracket the observed iron concentrations well once bisulfide concentrations exceed ca. 5 × 10-5 mol kg-1.
The use of Transbond Plus self-etching primer for preparation of demineralised enamel significantly increased microleakage at the adhesive-bracket interface on both sides of the brackets compared to that observed with conventional acid etching or NaF treatment.
The application of 2% sodium fluoride gel for 4 min before acid etching of demineralised enamel significantly reduced microleakage at the enamel-adhesive interface on both sides of the brackets compared to that observed in other study groups. .
The numbers of subtype within each family are indicated in brackets High redundancy was observed overall in the toxin genes, indicating that multiple toxin isoforms are highly expressed in the venom gland in contrast to non-toxin genes.
All the tested bracket slots were reobserved for asperities arising as a result of wire abrasion and also observed for bracket slot color changes arising from the metallic wire.
As much as 10° variation in torque has been observed when bracket placement differed by 1 mm [12].
