Surface quality achieved by polishing and by varnishing of temporary crown and fixed partial denture resins.

STATEMENT OF PROBLEM: Studies have suggested that coating a temporary restoration with varnish material could replace time-consuming polishing procedures needed for achieving an optimally smooth surface. PURPOSE: This study examined the surface roughness of acrylic resins after having been polished or coated with different varnish materials. MATERIAL AND METHODS: A total of 360 cylindrical specimens were fabricated from 9 brands of resin. One surface on each specimen was machined flat and subsequently either polished with rubber polishers or coated with 1 of 9 varnishes. Selected specimens were subjected to thermal cycling (5 degrees C to 55 degrees C, 2000 cycles). Surface quality was assessed by means of a profilometer and by SEM examination. RESULTS: Polished specimens had average surface roughness values (Ra) of 0.8 microm; differences in roughness between materials were small, but statistically significant. Type of coating had a significant influence on surface quality. Depending on the combination of materials used, the coating produced both smoother and rougher surfaces than polishing (0.4 microm < Ra < 4.6 microm). Five coatings were deemed not to be clinically applicable because of poor wetting properties. Thermal cycling did not significantly influence surface quality, but caused minute cracks in the cyanoacrylate coating. CONCLUSION: In regard to surface quality and applicability, the use of varnishes on temporary restorations is not advisable.

Fabrication of a duplicate denture using visible light-polymerized resin as an interim denture base.

This article describes a technique for producing a duplicate denture using a visible light-polymerized (VLP) denture base for support prior to processing. A 2-part mold of the original denture was made, and then a sheet of VLP resin was reduced to a thickness of 0.5 mm and adapted to the fitting surface of the mold to create a denture base. The base was polymerized and the remaining features, such as the teeth and polished surfaces of the denture, were reproduced in wax. This technique may be helpful when performing subsequent clinical and laboratory procedures.

Three-dimensional treatment planning for prosthetic rehabilitation.

All prosthetic rehabilitations require healthy, stable oral conditions. The biologic response to the preliminary treatment provides important criteria for planning the final reconstruction and permits testing of the desired prosthetic treatment goals within the unique patient-specific biologic conditions before final restoration. This study used long-term provisional restorations that corresponded in both form and function to the anticipated restorations. Intraoral testing of the diagnostic waxup is an outstanding basis for discussing the provisional as well as final restoration. As required, changes necessary to teeth form and position can be simply accomplished.

Apical healing of an endodontically treated tooth with a temporary restoration.

A 35-yr-old, healthy male presented to the graduate endodontic clinic at Indiana University School of Dentistry for treatment of tooth #26. Two and one-half yr after treatment, the patient returned to the dental school for comprehensive treatment. The canal access opening had been restored with an intact interim restorative material restoration. The tooth was asymptomatic, and radiographic examination showed evidence of apical healing. In this article, a review of the literature concerning crown-down leakage is presented. A case report is given in which healing occurred after the tooth was restored with only an interim restorative material for an extended period of time.

Solution for the isolation of the working field in a difficult case of root canal therapy.

A technique for the isolation of a posterior tooth with large distogingival caries and which needed endodontic therapy is described. To ensure a perfect seal, avoiding contamination or infiltration of the chemicals used for irrigation during the root canal therapy, a direct resin temporary restoration was done before placing the rubber dam as required for endodontic treatment.

Effect of intracanal medicaments on the sealing ability of TERM.

An in vitro leakage study was performed to determine the effect of intracanal medicaments on the sealing ability of Temporary Endodontic Restorative Material (TERM). Fifty extracted mandibular molars with uniform access preparations were restored with TERM after placement of either a dry cotton pellet (control) or a pellet moistened with eugenol, formocresol, CMCP, or a paste of sodium perborate and superoxol. Multiple quantitative measurements were made on each intact specimen at five time intervals after restoration, and, in some cases, after thermocycling. Statistical analysis revealed no significant leakage in the control group, or in the groups which used eugenol, formocresol, or CMCP when they were compared with the control group. Analysis, however, did show significant leakage for the group containing the bleaching paste. The authors concluded that the sealing ability of TERM is not affected by eugenol, formocresol, or CMCP. However, it should not be used for the temporary restoration of teeth being treated by the walking bleach technique.

The influence of coronal restoration type on the survival of endodontically treated teeth.

The aim of this study is to investigate the association between coronal restoration type and survival of endodontically treated teeth. A review was performed of treatment records of patients who had endodontic treatment performed in the Department of Restorative Dentistry, University Dental School & Hospital, Cork, Ireland during the period 1993-96. Demographic and dental factors such as age, gender, tooth type, coronal restoration type, and tooth status recorded at a review appointment were recorded. Tooth status at review was defined as 'tooth present' or 'tooth absent' based on the presence or absence of the endodontically treated tooth recorded in the treatment records at a review appointment held a minimum of one year following obturation of the root canal system. Of 176 teeth (166 patients) treated, survival of endodontically treated teeth was significantly more likely where restored with cast restorations (91.7%), amalgam restorations (86.5%), or composite restorations (83.0%), than teeth restored with temporary restorations (34.5%) (p<0.0001) (mean follow-up time 38 months, range 12-60 months). Survival of endodontically treated teeth was found to be associated with permanent coronal restorations. Loss of endodontically treated teeth occurred more often with those restored with temporary restorations (34.5%) than other restoration types (p<0.05).
