Factors Associated with Reevaluation of the Stepwise Excavation Procedure: An 8-Year Retrospective Study.

Although the stepwise excavation procedure (SWP) has been shown to be an effective caries treatment technique, studies reporting its application outside of controlled clinical trials are limited. We performed a retrospective study from patient record data to assess the proportion of patients who had an SWP reevaluated within 18 months at The University of Iowa College of Dentistry (UICOD) between 2004 and 2012, and evaluated the association between different variables and this outcome. A total of 1,985 SWPs were performed in 1,326 patients, with 518 patients having had reevaluation within 18 months.

Ethanol-wet bonding and chlorhexidine improve resin-dentin bond durability: quantitative analysis using raman spectroscopy.

Purpose: To directly test the effectiveness of ethanol-wet bonding (EW) in improving monomer infiltration into demineralized dentin through quantitative measurement of bis-GMA and TEG-DMA molar concentrations within hybrid layers, and to comprehensively evaluate the effect of EW and chlorhexidine on durability of resin-dentin bonds compared to conventional water-wet bonding (WW).

Materials And Methods: A three-step etch-and-rinse adhesive (70% bis-GMA/28.75%TEG-DMA) was applied to coronal dentin using a clinically relevant ethanol-wet bonding protocol (EW) or the conventional water-wet bonding (WW) technique.

Ceramic materials for porcelain veneers: part II. Effect of material, shade, and thickness on translucency.

Statement Of Problem: Information regarding the differences in translucency among new ceramic systems is lacking.

Purpose: The purpose of this study was to compare the relative translucency of the different types of ceramic systems indicated for porcelain veneers and to evaluate the effect of shade and thickness on translucency.

Material And Methods: Disk specimens 13 mm in diameter and 0.

Current strategies in dentin remineralization.

Partial caries removal procedures are used clinically in an attempt to conserve tooth structure and prevent pulp damage. Within this approach, the caries-infected dentin is removed, and the partially demineralized caries-affected dentin is preserved and sealed with materials that enhance remineralization. Fluoride-releasing glass ionomers have been commonly used for this purpose.

Violence and crime among male inpatients with severe mental illness: attempting to explain ethnic differences.

Background: Studies report that in the U.K., among men with severe mental illness (SMI), those of black Caribbean ethnicity display increased risk of aggressive behaviour, criminal convictions, and schizophrenia.

Ceramic materials for porcelain veneers. Part I: Correlation between translucency parameters and contrast ratio.

Statement Of Problem: Different parameters are used in the literature to describe translucency, making it difficult for clinicians to find clear information on ceramic translucency and compare studies.

Purpose: The purpose of this study was to assess the correlation between the contrast ratio (CR) and translucency parameter (TP) when the translucency of different types of ceramic systems is compared.

Material And Methods: Disks 13 mm in diameter and 0.

Effect of polishing direction on the marginal adaptation of composite resin restorations.

Problem: Polishing composite resin restorations may lead to marginal defects and gap formation.

Purpose: To assess the effect of polishing direction on the marginal adaptation of composite resin restorations using two composite resins and two polishing systems.

Materials And Methods: Forty extracted human molars were sectioned along their mesio-distal axis.

Consumers' choice of dentists: how and why people choose dental school faculty members as their oral health care providers.

This study aimed to better understand how and why people choose dental school faculty members as their oral health care providers. Increasing financial constraints in U.S.

Development and evaluation of an interactive dental video game to teach dentin bonding.

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled in the preclinical operative dentistry course. Students' change in knowledge was measured through written examination using a pre-test and a post-test, as well as clinical tests in the form of a benchtop shear bond strength test.

Restoring erosion associated with gastroesophageal reflux using direct resins: case report.

Gastroesophageal reflux disease (GERD) is a condition where stomach acids are chronically regurgitated into the esophagus and oral cavity, resulting in pathology, such as esophagitis, varices or ulcers. Continual exposure of the teeth to these acids can also cause severe dental erosion. This condition frequently is asymptomatic, and the only evident sign may be the irreversible erosion of tooth structure.

Impression matrix technique for cusp replacement using direct composite resin.

Unlabelled: Placement of Class II composite resin restorations often presents unique challenges in achieving proper contour and contact. Although the use of sectional bands has provided solutions to these problems, their use typically is limited to more ideal cavity preparations. With more extensive loss of tooth structure, recreating the natural tooth contours and contacts with direct resin composite can be difficult.

Evaluation of a glass-fiber-reinforced, bonded, inlay-supported fixed partial denture--4-year results.

Glass-fiber-reinforced composite resin systems may be used as conservative alternatives to conventional fixed partial dentures (FPDs) for the replacement of a single missing tooth. This article describes a clinical technique and 4-year evaluation of an inlay bonded FPD. The patient presented with a missing maxillary right second premolar.

Shade-match perception of porcelain-fused-to-metal restorations: a comparison between dentist and patient.

Background: Patient satisfaction with the shade match of restorations has not been appraised carefully in the dental literature. This study compared patients' and a prosthodontist's satisfaction with the shade o f existing porcelain-fused-to-metal, or PFM, restorations.

Methods: The authors selected a convenience sample of 212 patients for this study.
