Restorative Technique Selection in Class IV Direct Composite Restorations. A Simplified Approach
Reproducing esthetically pleasant anterior restorations requires that clinicians combine artistic skills with fundamental knowledge of tooth morphology along with selection and use of appropriate composite resin materials. The purpose of this table clinic is to describe in detail how one patient’s maxillary central incisors were restored using a simplified two-shade direct composite resin technique.

- Achieve natural contours in 4 simple steps
Protocols for Silver Diamine Fluoride Stain Reduction
Silver Diamine Fluoride (SDF) is very effective in caries prevention. It has been in use in many Asian countries. The major drawback is the resulting dark discoloration. We will present recent information regarding the use of SDF in the United States as a tooth desensitizer and its off-label use as a caries prevention agent. Experimental protocols to prevent discoloration will be discussed.

Effect of Composite Type and Placement Technique on Cuspal Strain
The emergence of bulk-fill composite resins on the market brings promise of simplified and expedited restorative techniques. This is a welcomed improvement since the placement of direct posterior composite resins using traditional incremental methods is both time-consuming and technique-sensitive. However, placement and polymerization in bulk brings concerns regarding several potential issues, among them the effect of polymerization shrinkage stress on the tooth-restorative interface. This table clinic illustrates a recent in vitro experiment where cuspal strain was measured in real-time while large MOD cavities in maxillary premolars where restored with 3 different types of bulk-fill restoratives, compared with a conventional composite resin placed incrementally.
- Cuspal strain as an effect of different restorative procedures (incremental placement vs. different bulk fill composite resins) will be illustrated
- The composition and properties of different bulk-fill composite resins will be explained
- The potentially adverse consequences of bulk-filling with traditional composite resins will be explained
The influence of Lead Content in Water and Its Effects on Properties of Tooth Structure Substrates
We evaluated the influence of lead (Pb) contaminated water at different concentrations on optical properties of restorative materials. Solutions were formulated by diluting a lead stock solution, varying at 4 different concentrations and pH of the water samples was adjusted to either 7 or 8. Two restorative materials resin composite (Premise, A2 shade, Kerr, USA) resin-modified glass ionomer (Fuji II LC, A2 shade, GC, Japan) were evaluated. Samples were prepared by using a PVS (Imprint 4, 3M ESPE) mold with internal dimensions of 6mm diameter x 2 mm thickness. In order to assess L*a*b* parameters, samples were evaluated by using a spectrophotometer (VITA Easyshade® Compact, VITA), using two different backgrounds (~0% [BB] or ~100% [WB] reflection). Radiopacity was assessed by radiographic analysis associated to aluminum-standard (step-wedge). After 1 day of storage, a reduction on b* and a* parameters was observed for all groups exposed to lead, higher when exposed to lower pH and higher lead concentrations. After 7 days, a reduction for L*, a* and b* parameters was observed for G while an increase was observed for C. Different concentrations of lead in water altered optical properties of restorative dental materials.

Dental Students’ Self-assessment in Pre-clinical Operative Procedures
“Self-assessment is critical for health care providers. The purpose of this study was to evaluate how dental students self-access their performance in pre-clinical operative procedures. It was shown that students had room for improving accuracy of self-assessment. Low-performing students had more accurate self-assessments and tended to under estimate themselves”.

Behavior of Fracture Resistance of Bonded Restorative Materials Supporting the Undermined Buccal Cusps: Strength Comparison
Studies have shown that preservation of tooth structure is the primary factor to producing a higher quality and longer lasting restoration. With bonded materials which mimic the properties of natural dental tissues, it is possible to allow the undermined cusps to remain supported properly by adhesive materials. This provides the opportunity to conserve tooth structure, maintain occlusal relationships, and potentially extend restoration survival.
- Increase the knowledge of different dental materials that act as dentin analogues which provide support to undermined enamel
- Compare relative strengths of material-dentin-enamel complexes subjected to thermal cycling and compressive forces
- Understand the relationship between base materials and structural reinforcement of load bearing surfaces

Influence of Core Buildup Materials in the Retention Form on Over-Prepared Teeth
A number of techniques have been suggested to improve retention of over-tapered crown preparations, including addition of retentive grooves and slots, use of bonded resin cements, and the use of core buildup materials to improve preparation form. The presented research will compare retention resistance form of ceramic crowns with different buildup materials on over tapered preparations.
