Evaluation of 660 nm LED light irradiation on the strategies for treating experimental periodontal intrabony defects.

This study aims to investigate the therapeutic value of 660 nm light-emitting diode (LED) light irradiation on the strategies for treating experimental periodontal intrabony defects in vivo. Large-sized periodontal intrabony defects were created bilaterally on the mesial aspect of the maxillary second molars of 48 Sprague-Dawley rats, and the rats were equally divided into four treatment groups with primary wound intention (n = 6/treatment/time point), including open flap debridement alone (OD), barrier membrane alone (MB), xenograft alone (BG), and xenograft plus barrier membrane (MG). Each group received daily 0 or 10 J/cm(2) LED light irradiation.

The Effect of Subepithelial Connective Tissue Graft Placement on Esthetic Outcomes After Immediate Implant Placement: Systematic Review.

Background: Immediate implantation, despite many advantages, carries a risk of gingival recession, papilla loss, collapse of ridge contour, and other esthetic complications. Soft tissue graft placement combined with immediate implantation may be used to reduce these concerns. This review aims to systematically analyze clinical esthetic outcomes of the immediate implant combined with soft tissue graft (IMITG).
