Purpose: To evaluate the cavity sealing obtained after thermocycling with five adhesive systems in which one all-in-one adhesive was compared to three one-bottle adhesives, and to observe the effect of a low-charged resin layer added to a one-bottle adhesive. Materials and Methods: Twenty-five recently extracted teeth were randomly allocated to five experimental adhesive systems (n = 5 each): Optibond Solo (OS), Scotchbond 1 (SB1), PQ 1, Prompt-L-Pop (PLP), SB1+Revolution (R). On each tooth, two rectangular cavities at the cementoenamel junction were filled with a microhybrid composite (Z100) and the tested adhesives. Teeth were thermocycled and stained with AgNO3 + vitamin C. Leakage was evaluated on a 6-point (0-5) severity scale and the highest score was selected for each restoration. Results were treated by ordinal logistic regression and considered to be significant at p < 0.05. Results: No significant difference was found between leakage values for enamel and dentin interfaces. Leakage scores never exceeded 2 for OS, SB1 and SB1+R, while they reached a maximum of 5 in 20% of PLP cases. OS was significantly better than the other adhesive systems, which were statistically equivalent. The addition of a flowable composite layer on SB1 did not yield a significant difference, but tended to give better results mainly at the dentin interface. Conclusion: The all-in-one adhesive PLP because of quite variable results, seems less reliable than the one-bottle adhesives, of which OS provides significantly the best results. Addition of a flowable composite on SB1 appears to yield slightly better results. [less ▲]

Counselling and drug prescription are the only means for the phycisian to manage dental emergencies. Among these, some are infection related: pulpitis, apical and periodontal abscesses, acute necrotizing ulcerative gingivitis and alveolitis. Urgent medical treatment includes antibiotics, mouth rinses and analgesics except for pulpitis (pain caused by thermal stimuli) for which analgesics alone are prescribed. Infection non related dental emergencies are: hemorrhage for which the best treatment is compression; trauma, mainly dental avulsion for which reimplantation must be done as soon as possible; acute TMD such as open lock which can be reduced by the Nelaton handling.
