Purpose: Arthrogenic temporomandibular disorders (TMDs) that do not respond to conservative treatment necessitate the use of semi-conservative methods, such as arthrocentesis. However, the ranking of intraarticular devices used in arthrocentesis remains controversial. Therefore, a network meta-analysis and systematic review were conducted to compare the different materials used for arthrocentesis.

Article Synopsis
- Human prion diseases are unusual brain illnesses that can spread and cause quick changes in memory and thinking.
- The study looked at a specific type called sporadic Creutzfeldt-Jakob disease (sCJD), examining data from over 3,700 cases to understand how long the disease lasts and at what age it starts.
- Researchers found important genetic clues on chromosome 20 that can help understand how long people live with this disease, especially one specific genetic change that seems to have a big effect on survival time.
Article Synopsis
- Patients increasingly want quick restoration of missing front teeth, but the effects of when to implant and how to load on esthetics and tissue health are unclear.
- This study systematically reviewed trials to compare outcomes and satisfaction across different single maxillary implant placement and loading strategies.
- Results showed that immediate implantation with immediate loading provided better esthetics and satisfaction than delayed methods, with no significant differences in bone loss between the protocols.
Objective: There are more than one million children and adolescents living with type 1 diabetes mellitus, and their number is steadily increasing. Diabetes affects oral health through numerous channels, including hyposalivation, immune suppression, and the inflammatory effect of glycation end-products. However, patients with type 1 diabetes must follow a strict sugar free diet that is proven to be carioprotective.

Objective: The study answers the PECO question: "In adults with dental implants (P), do subjects suffering from type-2 diabetes or prediabetes (E) have worse peri-implant conditions (O) than subjects without type-2 diabetes and prediabetes (C)?". Prediabetes (5.7-6.
View Article and Find Full Text PDFAlthough the development of aggregation assays has noticeably improved the accuracy of the clinical diagnosis of prion diseases, research on biomarkers remains vital. The major challenges to overcome are non-invasive sampling and the exploration of new biomarkers that may predict the onset or reflect disease progression. This will become extremely important in the near future, when new therapeutics are clinically evaluated and eventually become available for treatment.

Methods: An experienced operator conducted 40 digital scans of a 3D printed maxillary model and divided them into two groups: 20 with inclusion of the palate (PAL) and 20 without (NPAL). Each set of scans was performed using an intraoral scanner (IOS) (Trios 5; 3Shape A/S; Copenhagen, Denmark).
Human spongiform encephalopathies are rare transmissible neurodegenerative diseases of the brain and the nervous system that are caused by misfolding of the physiological prion protein into a pathological form and its deposition in the central nervous system (CNS). Prion diseases include Creutzfeldt-Jakob disease (CJD, sporadic or familial), Gerstmann-Straussler-Scheinker syndrome (GSS) and fatal familial insomnia (FFI). Prion diseases can be differentiated into three etiological categories: spontaneous (sporadic CJD), inherited (familial CJD, FFI, and GSS) and acquired (variant CJD and iatrogenic CJD).

Background: Subclinical myocardial injury in form of hs-cTn (high-sensitivity cardiac troponin) levels has been associated with cognitive impairment and imaging markers of cerebral small vessel disease (SVD) in population-based and cardiovascular cohorts. Whether hs-cTn is associated with domain-specific cognitive decline and SVD burden in patients with stroke remains unknown.
Methods And Results: We analyzed patients with acute stroke without premorbid dementia from the prospective multicenter DEMDAS (DZNE [German Center for Neurodegenerative Disease]-Mechanisms of Dementia after Stroke) study.
Prion diseases share common clinical and pathological characteristics such as spongiform neuronal degeneration and deposition of an abnormal form of a host-derived protein, termed prion protein. The characteristic features of prion diseases are long incubation times, short clinical courses, extreme resistance of the transmissible agent to degradation and lack of nucleic acid involvement. Sporadic and genetic forms of prion diseases occur worldwide, of which genetic forms are associated with mutations in PRNP.
