Using a dental air turbine and a mannequin, the authors recreated the droplets and aerosols that occur during dental procedures. The key is the high-sensitivity camera and high-intensity LED light source, which allowed for high-quality images of the droplet spreading during the simulated procedure. Using these techniques, the authors demonstrated efficient reduction of droplet and aerosol spread by using oral suction devices. Understanding the spread and diffusion of such particles in the air is a key step in successfully protecting individuals from potentially harmful diseases that can be spread through airborne droplets.
There is a debate among clinicians regarding severe endodontically treated teeth (ETT) in terms of residual tooth substance—whether to extract the tooth or perform partial ferrule. This work conducts the first meta-analysis study that introduces clear evidence-based guidance for clinicians regarding partial ferrule so that they can take appropriate clinical decisions and adequately plan restorative dental treatments of ETT.
The widespread use of Polyetheretherketone (PEEK) as an oral implant material is an ongoing topic of investigation. This review article summarizes the current surface modification strategies used to improve the binding efficiency of the emerging biomaterial PEEK with bone and soft tissues. Although many studies have shown that various surface modifications can successfully improve the biological activity of PEEK, further in-vivo experiments and long-term clinical evaluations are required to investigate the effects of various surface modifications on the tissue integration ability of PEEK implants.
To predict the success of prosthodontic treatments and plan effective maintenance care strategies, it is essential to precisely evaluate the risk factors. This retrospective study reports the 5- and 10-year survival of the abutment teeth of removable partial dentures. In addition to the presence of root-canal treatment at the baseline, postoperative radiographic changes in crown-root ratio and alveolar bone density on the denture side were significantly associated with abutment tooth loss.
In silico finite element analysis (FEA) has been widely used to evaluate stress/strain distribution in bone and implants under standardized conditions. The authors adopted a time-dependent FEA to evaluate the influence of subcrestal implant placement depth on bone remodeling. The time-dependent FEA demonstrated that an implant depth of more than 1.5 mm exhibited a high stress concentration and great overloading elements, particularly in cancellous bone. The established in silico approach will possibly become a useful tool to uncover the optimal implant placement depth that provides an appropriate bone response.
