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.

Learning Objectives:

  • To make transitional (composite/tooth) lines invisible
  • Obtain esthetic results with a single composite opacity
  • 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.

Learning Objectives:

  • The effectiveness of SDF as a caries prevention agent
  • The recent information regarding the use of SDF in the US
  • Effective protocols in preventing black discoloration

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.

Learning Objectives:

  • 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.

Learning Objectives:

  • Lead content and its influence on water
  • Lead content and its influence on tooth substrates
  • Elements effecting Mechanical properties of tooth

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”.

Learning Objectives:

  • The importance of self-assessment ability for dental care providers
  • The relationship between dental students’ preclinical skills and self-assessment skills
  • The relationship between dental students’ academic performance and self-assessment ability

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.

Learning Objectives:

  • 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

Custom Implant Abutments for Cemented Prosthesis: A Clinically-based Approach for Selection

The customization of abutments is an important factor in determining the success of an implant-supported restoration. The aim is to compare custom abutment materials for cemented implant prosthesis based on clinically relevant parameters: peri-implant tissues response, type of contour/emergence profile, cost involved, indications and contraindications, and esthetic use. Abutment materials compared are: titanium, titanium coated with titanium nitride, full zirconia, and zirconia with a titanium base.

Learning Objectives:

  • A comparison between different types of materials used for custom implant abutments for cemented prostheses based on clinically relevant parameters
  • Understand the inter-relationship between abutment design, margin placement, and the effects of soft tissue contour on the outcome of the implant supported restoration
  • The indications, use and type of material, and their effects in esthetics, semi-esthetic, and non-esthetic clinical scenarios

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.

Learning Objectives:

  • Review and discuss the selection of a core build-up material in the restoring over-tapered tooth after the removal of large dental caries or old restorations
  • Better understanding of the pulp’s response to core build-up materials, and the importance in maintaining the tooth’s vitality in any restorative procedure
  • Explain the step-by-step procedure for completing a core build-up, crown preparation, and cementation of ceramic crown restoration in the same visit
