METHODS: A total of 109 patients (55 female and 54 male; mean age: 51 +/- 14 years) with primary or secondary dentinal caries were randomly assigned to the two treatment groups of this biomedical clinical trial (phase III). Selection criteria were good systemic health and treated teeth, which were vital and showed no symptoms of pulpitis. Up to three teeth were prepared for indirect metallic restorations, and the provisional restorations were cemented with a triamcinolone/demeclocycyline (Ledermix) or a calcium hydroxide (Provicol) based material. The intensity of post-operative pain experienced was documented according to the VAS (4, 12, 20, 24, and 82 h) and compared to VAS baseline. RESULTS: A total of 159 teeth were treated (Ledermix: 83 teeth, Provicol: 76 teeth). The minor irritation of the teeth, experienced prior to treatment, was similar in both groups; however, 4 h after treatment this value was significantly higher in the Provicol group than in the Ledermix group (p < 0.005, t-test). After 12 h, the difference was no longer significant. The number of patients taking analgesics for post-treatment pain was higher in the Provicol group (n = 11/53) than in the Ledermix group (n = 3/56). CONCLUSIONS: The patients had no long term post-operative pain experience in both groups. However, within the first hours after cementation the sensation of pain was considerably higher in the Provicol group than in the Ledermix group.

A total of 286 extracted human maxillary incisors (145 central and 141 lateral incisors) were included in this investigation. Exclusion criteria were teeth with extensive carious lesions, restorations, and root canal treatment. For this in vitro study, the teeth were fixed in a special device and digitally x-rayed with the parallel technique. The distances from the cementoenamel junction (CEJ) to the first curvature and the according angle were recorded. The results were analyzed descriptively, and p values were calculated with the Wilcoxon Mann-Whitney test. The mean distance between the CEJ and the first curvature of the central maxillary incisors was 10.4 mm (standard deviation [SD] +/- 2.8) and that of the lateral incisors was 11.1 mm (SD +/- 3.0). Most of the central incisors (right: 94.2%, left: 98.7%) and all of the lateral incisors exhibited curvatures. Statistically significant differences between central and lateral maxillary incisors could be observed regarding the canal curvature locations (p = 0.016) and the angle values (p < 0.001), but there was no statistical difference between the right and the left side. The results showed the high percentage of root canal curvatures in maxillary incisors with a mean curvature located 10.7 mm apical from the CEJ. These findings are important to minimize failures during post insertion.
