Patient Preferences and the Measurement of Utilities in the Evaluation of Dental Technologies

S. Birch and A.I. Ismail
In this period of rapid biotechnological inventions that may significantly affect the provision of health care, assessing the preferences of patients and the public for health outcomes of new technologies would be necessary to help health professionals and policy makers make appropriate decisions. This review describes and critiques the different measurement methods of preferences under conditions of certainty and uncertainty (or utilities).

Task-dependence of Activity/ Bite-force Relations and its Impact on Estimation of Chewing Force from EMG

P.A. Proeschel and T. Morneburg
Different activity/force characteristics in dynamic and isometric biting can cause overestimation when chewing force is predicted from masticatory electromyograms.

Two Modes of Nanoleakage Expression in Single-step Adhesives

F.R. Tay, D.H. Pashley, and M. Yoshiyama
Although contemporary single-step, self-etch adhesives are user-friendly because of their reduction in the number of bonding steps, the benefit of saving time may be achieved at the expense of compromising the durability of resin-dentin bonds.

Reversal of Compromised Bonding in Bleached Enamel

S.C.N. Lai, F.R. Tay, G.S.P. Cheung, Y.F. Mak, R.M. Carvalho, S.H.Y. Wei, M. Toledano, R. Osorio, and D.H. Pashley
Reduction of resin-enamel bond strength in bleached etched enamel is likely to be caused by a delayed release of oxygen that affects the polymerization of resin components.

Enhanced Hydrolytic Stability of Dental Composites by Use of Fluoroalkyltrimethoxysilanes

T. Nihei, S. Kurata, Y. Kondo, K. Umemoto, N. Yoshino, and T. Teranaka
Polyfluoroalkyltrimethoxysilanes, which are strongly water- and oil-repellent, promote the sealing of filler surfaces and will thus produce more durable resin composites.

Cystic Fibrosis Transmembrane Regulator Gene (CFTR) is Associated with Abnormal Enamel Formation

C.K. Arquitt, C. Boyd, and J.T. Wright
This study indicates that enamel in the murine cystic fibrosis mouse develops abnormally, with altered cystic fibrosis transmembrane regulator protein gene expression in odontogenic cells as the likely etiology.
