Background: Using a single-blind, randomized, controlled, multicenter, practice-based clinical trial, a volume-stable collagen matrix (VCMX) was compared with connective tissue graft (CTG) for soft tissue augmentation around existing dental implants.

Methods: Sixty patients (31 VCMX and 31 CTG) were included. The primary outcome was a soft tissue thickness change 3 mm below the gingival margin (GM).

Postextraction bone grafting and implant placement help preserve alveolar bone volume. Collagen wound dressings and soft tissue graft substitutes may help protect extraction socket bone grafts and provide better gingival contours. This randomized, controlled, multicenter, and double-blinded study was conducted to compare a control (wound dressing) and a test (soft tissue graft) substitute in nearly intact extraction sockets.

Background: Saliva is an active carrier of SARS-CoV-2, and antimicrobial mouthrinses can be rendered less effective by saliva. Aerosol-generating procedures are commonplace in dentistry, and preprocedural mouthrinses and/or irrigation with effective SARS-CoV-2 virucidals should be tested in the presence of saliva.

Methods: With the use of an in vitro virucidal suspension test, molecular iodine oral rinse was assayed against SARS-CoV-2 with and without saliva after 30- and 60-second exposures to the rinse.

Focused Clinical Question: What are important considerations for selecting a predictable regenerative surgical approach for intrabony defects? Summary: The predictable regeneration of intrabony defects remains an important goal in the management of periodontitis. Clinical and histologic evidence of periodontal regeneration has been shown for multiple regenerative therapies, including bone replacement grafts, guided tissue regeneration, and biologics, when used alone or in combination. Regenerative therapies improve periodontal health, as evidenced by gains in clinical attachment level, reductions in probing depth, and gains in radiographic bone fill.

Background: Treatment of intrabony defects is an important therapeutic goal of periodontal therapy. The goal of this consensus report was to critically appraise the evidence for the available approaches for promoting periodontal regeneration in intrabony defects. In addition to evaluating the effectiveness of new regenerative approaches for intrabony defects, recommendations for future research were defined for this area.

Long-term success of dental implants is linked to well-trained implant surgeons and restorative dentists working together with the most advanced treatment modalities. General dentists are challenged to identify early in the diagnosis patients who are at greatest risk for developing complications and partner with specialists in formulating treatment plans.

The objective of this study was to quantify new bone formation from biopsies of demineralized freeze-dried bone allograft (DFDBA) and freeze-dried bone allograft (FDBA) following ridge and sinus augmentations. Ninety-three patients who received maxillary sinus or ridge augmentation grafts agreed to core biopsies of their grafts when the implants were placed. Samples ranged from 6 to 36 months postgrafting.
