A Cavity Preparation Evaluation System in the Skill Assessment of Dental Students

Journal of Dental Education, 2016
The aim of this study was to compare a computerized, laser‐scanning Cavity Preparation Skill Evaluation System (CPSES) with conventional teachers’ eye‐hand grading assessment of dental students’ Class I cavity preparation evaluations. Thirty‐eight cavity preparations of lower left first molars made by junior dental students at a dental school in China ...

Alteration of odontoblast osteonectin expression following dental cavity preparation

Archives of Oral Biology, 2001
Cavity preparation can increase the active synthesis and secretion of non-collagenous proteins by odontoblasts, thus resulting in the deposition of tertiary dentine. In this study, the effect of cavity preparation on osteonectin expression was examined in odontoblasts of the rat tooth pulp. A class V cavity was prepared in rat first molars to stimulate

The Effect of Cavity Preparation on Substance P Expression in Human Dental Pulp

Journal of Endodontics, 2005
Substance P (SP) plays an important role during neurogenic inflammation of dental pulp. The purpose of this study was to use a radioimmunoassay for determining the effect of cavity preparation on SP expression in healthy human dental pulp. Ten pulp samples were obtained from healthy premolars where extraction was indicated for orthodontic reasons. Deep

Repair in the human dental pulp following cavity preparation

Archives of Oral Biology, 1970
Abstract The reactions following cavity preparation with a Borden air turbine handpiece were studied in ninety-three caries-free young premolar teeth. Immediate damage to the dental pulp was greater in air-cooled than water-cooled specimens and this greater degree of injury was evident up to 15 days post-operatively.

Adaptation of dental amalgam to the cavosurface margin of Class I cavity preparations

Journal of Oral Rehabilitation, 1987
SummaryThe adaptation of a range of amalgam alloys to the cavosurface margin of Class I cavity preparations was examined for two condensation techniques. The marginal contour of amalgam condensed into the cavity preparation and packed approximately 1 mm past the cavosurface margin was compared with amalgam margins of restorations which were packed to ...

Conservation of the dental pulp—Cavity preparation

The Journal of Prosthetic Dentistry, 1959
Abstract The thoughts in this article may be summarized by stating that patients with dental caries are afflicted by a serious ailment. Their teeth are diseased and have carious lesions within them. When a carious lesion is excised, living tissues are cut. Excision of viable dentin is excision of extended living pulp.

Clinical Dental Application of Er:YAG Laser for Class V Cavity Preparation

Journal of Clinical Laser Medicine & Surgery, 1996
Following the development of the ruby laser by Maiman in 1960, the Nd:YAG laser, the CO2 laser, the semiconductor laser, the He-Ne laser, excimer lasers, the argon laser, and finally the Er:YAG laser capable of cutting hard tissue easily were developed and have come to be applied clinically.
