Effectiveness and feasibility of utilizing E4D technology as a teaching tool in a preclinical dental education environment.

Recent efforts have been directed towards utilizing CAD/CAM technology in the education of future dentists. The purpose of this pilot study was to investigate the feasibility of implementing CAD/CAM technology in instruction on preparing a tooth for restoration. Students at one dental school were assigned access to CAD/CAM technology vs.

Estimation of transpalatal nasalance during production of voiced stop consonants by noncleft speakers using an oral-nasal mask.

Objective: Our objective was to estimate nasalance due to transpalatal transfer of acoustic energy during production of voiced stop consonants by noncleft speakers. We also determined the relationship between the transpalatal nasalance and fundamental frequency (F0) of the speakers.

Method: Participants were 8 men and 10 women (mean age = 21.
