Reactions: Antibacterial and bioactive dental restorative materials: Do they really work?

Purpose: The study and development of antibacterial materials for use in dental applications is growing with the development of novel materials and procedures. Examination of the effects of such antibacterial materials on oral pathogens as well as on stability and longevity of dental restorations is of paramount importance to the field.

Results: This review addressed the range of topics covered by the manuscripts presented at the Seoul symposium on antibacterial dental materials.

Gingival curettage study comparing a laser treatment to hand instruments.

The purpose of this clinical study was to examine nonsurgical treatments of periodontal disease comparing a diode laser to subgingival curettage with conventional hand instruments. The study group comprised 18 patients with moderate periodontal degradation who were treated without local anesthesia. Each quadrant was randomly allocated in a split-mouth design either to treatment with a 810-nm diode laser using an energy of 2 W (test group) or to gingival curettage using hand instruments (control group).
