Summary: Arazyme, a metalloprotease produced from Serratia proteamaculans HY-3, showed strong proteolytic activities over a wide range of temperature and pH. It demonstrated efficient denture cleaning and antimicrobial effects, inhibiting the growth of major oral opportunistic pathogens, such as C. albicans, with more than 80% inhibition at a concentration of 250 mg/mL. Arazyme has potential as a biological oral health care agent and a source for developing novel denture care products.

Summary: Recent technological developments in implant overdenture attachments were reviewed, focusing on attachment systems, retention, stress distribution, design, digital techniques, and peri-implant health effects. Plastic and nylon resins are commonly used in different attachments. Ball and locator systems are considered the best overdenture systems with superior tissue response and patient satisfaction.

Summary: This study assessed the oral hygiene of patients prosthetically treated at the Dental Prosthetics Clinic of the University Dental Clinic in Krakow, Poland, finding that patients using dentures generally had poor oral hygiene regardless of the type of dentures used. The most common group to receive prosthetic treatment were women with secondary education, and the majority of patients at the Dental Prosthetics Clinic lived in large cities, likely due to easier access to healthcare.

Summary: This study retrospectively analyzed patients restored with implant-supported overdentures using different attachment systems. The analysis showed that bar attachments had fewer complications compared to telescopic crowns and Locator-type attachments. In vitro testing found that telescopic crowns caused the highest strain during insertion and loading, while Locators with white retentive inserts caused the highest strain during removal. The novel NiTi flexible attachment system exhibited lower strain development during insertion, loading, and removal, suggesting its potential benefits in terms of component wear and implant loading.

Summary: Young patients with ectodermal dysplasia and Ehlers-Danlos Syndrome present unique oral characteristics and treatment challenges, including congenitally missing teeth and easily traumatized oral structures. Incorporating digital technologies in their oral rehabilitation shows potential benefits for these patients' quality of life.

Summary: This study evaluated the microbiological and immune response associated with peri-implantitis compared to healthy implants. It found that peri-implantitis has a complex and different microbiota, including bacteria, archaea, fungi, and viruses, which may trigger higher inflammatory response and osteolytic activity, contributing to the pathophysiology of peri-implantitis.

Summary: This study developed dental adhesives containing superparamagnetic iron oxide nanoparticles (SPIONs) to enhance penetrability into dentin guided by a magnetic field. The adhesives were tested for physical, chemical, antibacterial properties, and cytotoxicity. By simulating pulpal pressure concurrently with a magnetic field, it was shown to be feasible to overcome the jeopardization on bond strength caused by pulpal pressure. The magnetic-responsive adhesives showed great potential to improve bond strength, presenting a promising strategy to enhance resin-based restorations' longevity without affecting biological properties of adhesives.

Summary: The prevalence and risk factors associated with incidental calcified atheromas in routine dental cone beam computed tomography (CBCT) images were assessed in this study. CBCT images of 458 subjects were evaluated and divided into 4 groups based on the presence of calcified atheroma. The results showed that 29.90% of the CBCTs had calcified atheroma, and it was more common in older male patients. Patients with calcified atheroma were more likely to have a history of hyperlipidemia, hypertension, and cardiovascular diseases. Subjects with combined atheroma lesions had a higher risk for cardiovascular disease.

Summary: The microbiome composition within dental implants of subjects with peri-implantitis and healthy controls was characterized using 16S rRNA gene sequencing. The results showed a significant increase in microbial diversity in the internal implant surface of peri-implantitis subjects compared to healthy controls. The bacterial community structure was also different between the two groups, with a higher abundance of Gram-positive bacteria, especially Enterococci, in peri-implantitis implants.

Summary: This study compared two workflows, duplicate dentures (DDs) and occlusion rims (ORs), for transferring occlusal vertical dimension (OVD) when designing and fabricating digital dentures. The results showed that the DD workflow had less deviation in OVD transfer compared to the OR workflow, but the deviation may not be clinically significant.

Summary: This study characterized the microbiome composition in the peri-implant pocket of peri-implantitis and peri-implant control sulcus using 16S rRNA gene sequencing. The results showed that the peri-implant control sulcus harbored predominantly Gram-positive bacteria, while the peri-implant pockets of implants with peri-implantitis predominantly harbored Gram-negative bacteria.

Summary: This research developed novel low-shrinkage-stress nanocomposites containing DMADDM with nanoparticles of nCaF(2) or NACP for tooth remineralization. These nanocomposites exhibited excellent antibacterial properties and cytocompatibility, while also maintaining good mechanical properties. They have the potential to improve dental restorations by reducing shrinkage stress and preventing cariogenic biofilms.
