The success of emergency pulpotomies in primary molars.

PURPOSE: The purpose of this retrospective study was to assess the success of pulpotomies performed on an emergency basis and restored with a temporary zinc-oxide eugenol restorative material. METHODS: Records were collected from 216 pulpotomies in primary molars performed on an emergency basis by pediatric dental residents at the University of Florida pediatric dental clinic between July 1999 and June 2001. The selection criteria include teeth with a positive history of pain but with absence of clinical and radiographic signs of pulp degeneration. Formocresol was the medicament used and the teeth were restored temporarily with a reinforced zinc-oxide eugenol material. Treatment success or failure was determined, at the definitive restorative appointment, by the presence or absence of clinical and/or radiographic pathology. The time interval between emergency and definitive treatment appointments, tooth-type, arch, age, and gender were the variables analyzed in this study. Chi-square analysis was used to assess the effect of the different variables on the outcome of the treatment. RESULTS: Sixty-four teeth were available for assessment in the two-year period. A 53% success rate was observed, if the tooth was evaluated and restored with the definitive restoration, within the first 90 days post-emergency treatment. A 31% success rate was observed after 365 days. These results were statistically significant (P=0.016). Patients younger than six years old showed statistically significant higher chances for success than older children did (P=0.018). No significant differences were found for gender, type of tooth, or arch. CONCLUSIONS: The low success rate found during the first three months post emergency treatment may be attributed to undiagnosed, subclinical inflamed pulp, while long-term failure may be associated with microleakage of the temporary restorative material.

Evaluation of resins for provisional restorations.

An in vivo study of two resin materials (Barricaid and Caulk Temporary Crown and Bridge Resin) was done to determine the retention, post-operative sensitivity, and fabrication time of provisional restorations made from these materials. Following the placement of these resins in 67 intracoronal cavity preparations of 19 adult patients, a baseline evaluation was made which included a clinical examination and color slides. Twenty-four hours after the temporary restorations were placed, the patients completed evaluations of the post-operative sensitivity experienced. There was no difference in post-operative sensitivity between the teeth restored with Barricaid or Caulk Temporary Crown and Bridge Resin. At the insertion appointment of the final restoration, the interim restoration's success rate was determined. There was no difference between the retention of the two provisional materials. Fabrication time was significantly different with Barricaid restorations requiring less than one-half the fabrication time of the Caulk Temporary Crown and Bridge Resin material.

Prevalence and distribution of dental restorative materials in US Air Force veterans.

OBJECTIVES: Millions of restorative procedures are performed annually in the United States, yet very little is known about their distribution in the general population. With increasing concern about potential adverse health effects of some restorative materials, a better understanding of the extent of exposure to these materials in the population is important. The purpose of this study is to report the prevalence, patterns, and distribution of dental restorative materials in a population of male veterans. METHODS: This collaborative study with the US Air Force examined 1,166 male veterans to assess exposure to dental amalgam and other restorative materials. An inventory of dental materials in the study population was obtained through oral examinations. Dental materials were classified into five categories: (1) amalgam; (2) resin; (3) porcelain, cement, or temporary, including ionomer (PCT); (4) cast gold alloys/direct filling gold; and (5) other metals (OM). The mean age of the study participants was 52.9 years. Over 94 percent of the study participants were dentate. RESULTS: The study participants averaged 45.8 restored/replaced surfaces. Restored/replaced surfaces increased with age while the number of teeth decreased with age. The most frequently used restorative material was amalgam, averaging 19.89 surfaces per subject, followed by PCT (9.38), resins (8.99), OM (5.52), and gold (4.91). The distributions of restorative materials varied by age, arch type, and location in the mouth. CONCLUSION: The study population experienced substantial exposure to dental materials.

Progressive decrease in dentine permeability following cavity preparation.

Dentine permeability determinations were made longitudinally in cavities prepared in dog teeth in vivo, using two different techniques: isotope clearance and fluid filtration. Measurements made with both techniques indicate that there is a large reduction in dentine-permeability within the first week following cavity preparation. The phenomenon requires an intact pulp and is not the result of microleakage of temporary restorations.
