The phenomenology of false memories: episodic content and confidence.

Three experiments investigated the phenomenology of false memories in J. D. Bransford and J. J. Frank's (1971) semantic integration paradigm using Remember-Know judgments and confidence ratings. Findings included high rates of Remember false alarms that increased with greater integrative demands, a dissociation between Remember and Know judgments in the standard Bransford and Franks condition, and similar patterns of Remember and Know judgments in a condition where semantic integrative processes were weakened. Confidence ratings were consistently higher for Remember judgments except where integrative processes were greatest. These results are discussed in terms of the phenomenology of true and false memory for episodes.

Marginal accuracy of provisional restorative materials.

Marginal integrity is an important quality in the provisional restoration. Previous studies on marginal integrity have presented conflicting results. In addition, newly available resins are making the selection of an accurate resin for provisional restorations difficult. The objective of this study was to evaluate the marginal accuracy of seven commercially available resins by using an established indirect technique, and to evaluate the effect of water absorption on polymerization shrinkage. Eight specimens of each material were tested under three conditions: immediately after polymerization, after 1 week of dry storage, and after 1 week of storage in room temperature water. Three materials, Duralay, Cold Pac, and Snap resins, produced statistically significantly superior marginal adaptation. Water absorption appeared to compensate for continued polymerization shrinkage.

The effect of clinical remount procedures on the comfort and success of complete dentures.

Fifteen patients were treated with complete dentures in a routine manner that included a clinical remount. A second group of 15 was treated in the identical manner except that the clinical remount was not performed. The occlusal patterns of all dentures were recorded in the patient's mouths at delivery and again 1 week later by using a photoelastic membrane to provide a permanent record. The presence or absence of soreness was also noted for each patient during the week after delivery. Results indicate that clinical remounts significantly reduced the incidence of soreness, preserved the occlusal force, and reduced the changes in occlusal patterns of the dentures. Although both cusped and flat teeth were used in both treatment groups, no significant differences were noted in relation to either form on the basis of the indices studied.

Attitudes toward abutment preparation for removable partial dentures.

A questionnaire was sent to 58 dental schools to determine what type of abutment preparation is being used in conjunction with removable partial dentures. Responses from 43 schools indicate that enamel modification and cast restorations are still the primary type of abutment preparations. Amalgam alloys are widely used, and composite and acid-etched retained restorations are also being used.

Pressure indicators for removable prosthodontics.

P.I.P. and Coltene pressure spot indicator were tested on the same 30 sets of complete maxillary and mandibular dentures and on two maxillary dentures against natural dentition. They were tested at delivery for pressure spots, but adjustments were not made. They were tested again after 24 hours to visualize and compare actual pressure spots. Half the dentures were adjusted according to P.I.P. and half according to Coltene pressure spot indicator. The patients were recalled after 1 week to determine if they were free from discomfort. The P.I.P. showed a greater clinical correlation of predictable to actual pressure spots and enabled the investigators to spare more patients from post-delivery discomfort.
