Purpose: To evaluate the 6-month clinical performance of the etch-and-rinse one-bottle adhesive system XP BOND, used in combination with the composite resin Ceram X duo for the restoration of Class V noncarious cervical lesions (NCCL).
Materials and Methods: XP BOND was tested in a total of 40 patients who received two Class V Ceram X duo restorations, Adper Scotchbond 1 XT was used as a control. After cleaning the teeth, the surface of the NCCL was treated using a carbide bur in dentin and a 40-µm diamond bur in enamel with no retentive preparations. The lesions were filled with two increments of Ceram X duo after the application of the respective adhesive by a single operator according to manufacturer's instructions. After 6 months, the retention and the marginal integrity were evaluated.
Results: Thirty-eight of 40 patients were evaluated after 6 months by two clinicians according to modified USPHS criteria, and all restorations using XP BOND were still in place. In the control group (using Adper Scotchbond 1XT), one restoration was lost. The statistical evaluation (chi2 test) showed no significant differences in any of the criteria. No difference of marginal integrity was found between the two adhesive systems.
Conclusion: XP BOND meets the ADA success criteria after 6 months.

The quality of fillings consisting of a hybrid composite was compared with fillings consisting of two different microfilled composites in a clinical examination.
Within the design of a clinically controlled two-year study conducted under practice-relevant conditions, the composites C-Fill MH (Megadenta), Helio Progress (Vivadent), and Visio-Dispers (ESPE) were examined in anterior-tooth cavities in 134 patients by means of the split-mouth technique. The clinical examinations were performed based on modified Ryge criteria (marginal integrity, anatomical form, secondary caries, color, marginal discoloration, surface roughness) after 12 and 24 months.
Immediately following filling application, all evaluation criteria except color were assessed as level A. After 12 and 24 months, C-Fill MH was found to be significantly superior to the other materials with regard to marginal integrity, color, and marginal discoloration.
The hybrid composite C-Fill MH seems to be superior to the microfilled composites and should therefore be preferred as a restorative filling material.

From a theoretical point of view, caries can be prevented by perfect oral hygiene and sugar abstinence. However, practice has shown that this approach is successful in individual cases only. For the whole population, effective caries prevention is still not realistic without the use of fluoride in various forms. The use of different fluoride preparations increases its efficacy. On the other hand, correct dosage is important to prevent the risk of dental fluorosis. Most of the European scientific dental associations no longer recommend the use of fluoride supplements, such as fluoride tablets or drops, as a standard procedure in caries prevention. This is due to the increasing evidence that the effect of fluoride is mainly the result of chemical reactions on the tooth surface. Therefore, fluoridated toothpastes, gels, varnishes, and rinses are more in focus. Besides this, fluoridated water and fluoridated salt are still important. Although they have a systemic effect, the efficacy of these fluoride applications results from local processes.
