Posterior composites: update on cavities and filling techniques
Conclusions Minimum cavity preparations are advised for posterior resin composite restorations, preserving the greatest amount of healthy tooth structure. For resin composite restorations only the caries lesion needs to be removed with all remaining tooth structure protected for the bonding process. The anticipated outcome of this philosophy will result in the longer survival of teeth. Newer bulkfill restorative resins allow the operator to complete the restoration in a similar time to the placement of a dental amalgam restoration. (Source: Journal of Dentistry)

Re-interventions after restoring teeth —Mining an insurance database
Conclusions The sustainability of restorative dental treatment under the terms and conditions of the German national health insurance system shows room for improvement. From a public health perspective, special focus should be laid on primary and secondary prevention to minimize the restorative treatment need. Clinical significance statement This study shows that re-interventions are observed regularly after restorative treatment. Therefore, preventive and restorative strategies should be revisited and optimised. (Source: Journal of Dentistry)

Own brand label restorative materials —A false bargain?
Conclusions The OBLs were in general outdone by the conventional composite. Clinical significance OBLs restorative materials have become pervasive in the dental market. Manufacturers often promise equal or better characteristics than existing brand-name composites, but at a lower price. Dentists are highly recommended to reconsider utilization of OBLs lacking sound scientific scrutiny, and our findings underscore this recommendation. (Source: Journal of Dentistry)

Penetration of sub-micron particles into dentinal tubules using ultrasonic cavitation
Conclusions The cavitation bubbles produced from an ultrasonic scaler may be used to deliver sub-micron particles into dentine. This method has the potential to deliver such particles deeper into the dentinal tubules. Clinical significance Cavitation from a clinical ultrasonic scaler may enhance penetration of sub-micron particles into dentinal tubules. This can aid in the development of novel methods for delivering therapeutic clinical materials for hypersensitivity relief and treatment of dentinal caries. (Source: Journal of Dentistry)

Micro-CT analysis of naturally arrested brown spot enamel lesions
Conclusion This study demonstrated that the mineralization parameters such as density and the thickness of the surface layer as well as distribution patterns through natural enamel brown spot lesions (BSLs) are different from enamel white-spot lesions (WSLs). The higher mineral density of the body of the lesion and the increased thickness of the surface layer in brown spot enamel lesions may suggest possible subsurface remineralization in the majority of naturally arrested BSLs.
