Factors associated with continuing pain in endodontics.

A survey of 100 patients referred to a specialist endodontic practice was undertaken to determine the frequency of various factors associated with continuing pain after endodontic treatment had been commenced by the patient's general dental practitioner. Information was obtained by questioning the patient, examining the tooth, reviewing information supplied by the referring dentist and by observation during subsequent treatment. There were 23 different factors associated with continuing pain--all patients had more than one factor; most (78 per cent) had four, five or six factors; the highest was 9 factors (2 per cent). The most commonly occurring factors were: lack of use of rubber dam (87 per cent), unsatisfactory temporary restorations (80 per cent), and inappropriate use of intracanal medicaments (71 per cent). The other factors were related to diagnostic or treatment errors that could have been avoided in most cases. This survey suggests that dentists need to pay more attention to basic treatment recommendations in order to predictably relieve pain when carrying out emergency endodontics.

Temporary and permanent restorations for fractured permanent teeth with immature apices: a clinical study.

Clinical and radiological studies of the fractured teeth of patients between seven and eleven years old were conducted to assess the use of permanent and immediate (emergency) techniques for reconstructing anterior permanent teeth with immature apices. The general hypothesis states that, given the physical and biocompatible properties of the materials used in the immediate (emergency) technique, there are no significant differences between the two techniques as far as pulp vitality and apical growth are concerned. A sample of fifty-six patients was selected. They had Class I, II or III fractures, for which permanent and immediate (emergency) techniques were used in equal numbers. Thermal, mechanical, and electrical tests were used to evaluate pulp vitality compared with the homologous tooth. Apical convergence was the radiological criterion used for determining the end of the radicular process. After one year, both techniques allow preservation of pulp vitality. Results show that, unlike the conventional technique (permanent), radicular formation was completed first in teeth reconstructed using the immediate (emergency) technique. Statistical analysis shows no definitive relationship between the technique used and completion of apical growth time (P > 0.05). In conclusion, comparison between the mediate (permanent) and immediate (emergency) techniques shows that the immediate (emergency) technique is an adequate alternative for reconstructing fractured teeth, because of the greater esthetic and functional advantages at the patient's disposal.

Comparison of endodontist versus generalist regarding preference for postendodontic use of cotton pellets in pulp chamber.

A degree of uncertainty exists about the use of cotton pellets in the pulp chamber after canal obturation. The purpose of this study was to poll practicing endodontists and generalists regarding their preference. Forty-six endodontists and an equal number of general dentists were polled in a mail survey regarding their preferences for the use of a cotton pellet in the pulp chamber after canal obturation. Eighty-seven percent of the endodontists and 54% of the generalists responded. Of the endodontists, 62.5% said they thought that the general dentist wanted a cotton pellet, contrasted to 80% of the generalists. The difference in proportions was not statistically significant.

In vitro color stability of provisional crown and bridge restoration materials.

Discoloration of provisional restorations can be an esthetic problem, especially when the treatment plan requires long-term provisionalization. In this study, therefore, we examined the effects of staining solution on the color stability of these provisional crown and bridge restoration materials: Structur, Temdent, and Tab 2000. Treatment solutions were namely carrot juice, tea, cola, light cola, and distilled water. Thirty samples were prepared for each type of provisional material, such that a total of 90 samples were prepared. The color value of each sample was measured with a colorimeter at baseline and after one day, one week, two weeks, and four weeks of immersion in various treatment solutions. Results were determined using the CIELAB system. Color change data were calculated and subjected to two-way analysis of variance. To examine significant interactions, one-way ANOVA and Tukey's multiple comparisons test were performed to identify differences between the solutions (p < or = 0.05). After four weeks of treatment, color difference values were found to range from 0.20 to 3.99 deltaE* units. The highest color difference values were obtained in carrot juice, cola, and tea with Structur samples after four weeks, where these values were categorized as "noticeable" and "unacceptable" color change values. Based on the results of this study, we do not recommend amine-containing Structur to be used as a provisional crown and bridge restorative material for treatments of a longer duration.

Customized abutments to shape and transfer peri-implant soft-tissue contours.

With the functional successes of implant therapy being realized, the emphasis is shifting to the creation of tooth-like esthetics with implant therapy. Dental implants are placed after careful planning and site preparation, which may include bone and soft tissue grafting. The final soft tissue appearance is enhanced through the early use of provisional restorations. A combination technique is described to fabricate provisional healing abutments for cement-on prostheses and to transfer the individualized peri-implant soft-tissue contours to the dental laboratory. This technique will allow the practitioner to deliver highly customized implant care with familiar techniques and readily available materials.
