Article Synopsis
  • The study evaluated the impact of photobiomodulation therapy (PBM) and leukocyte plasma-rich fibrin (L-PRF) on improving dental implant stability in patients missing posterior mandibular teeth.
  • Fifteen patients received two implants; one side used PBM and L-PRF, while the other served as a control. Results showed significant improvements in implant stability, especially with the 650 nm laser treatment.
  • Findings suggest that combining PBM and L-PRF can enhance osseointegration and should be considered in dental implant procedures, particularly in the posterior mandible for optimal stability.

Background: Challenges in the root canal system, such as isthmus, may limit the action of endodontic equipment and irrigation solutions, so using laser agitation is recommended to upgrade the removal of microbial biofilm. The objective of this study is to assess the effectiveness of the laser in photon-induced photoacoustic streaming protocol agitation of 2% chlorohexidine gluconate in removing mature biofilm in complex root canal systems.

Material And Methods: Seventy-five mesial roots of the lower first and second molars were separated and cultivated with Enterococcus faecalis bacteria for 30 days (except for the negative control group samples).

Sepsis remains a public health issue with high morbidity and mortality. Liver injury due to sepsis is associated with poor outcomes and an increased risk of death among septic patients. Rebastinib is a small molecule inhibiting the Tie2 receptor and vascular endothelial growth factor receptor-2 (VEGFR2).

Sepsis, a life-threatening condition resulting from an uncontrolled host response to infection, often leads to severe liver damage and remains a significant cause of mortality in critically ill patients despite advances in antibiotic therapy and resuscitation. Bevacizumab, a neutralizing antibody targeting vascular endothelial growth factor (VEGF), is approved for treating certain cancers. However, its potential impact on sepsis-related liver injury is not well understood.

  • Head and neck cancer (HNC) involves cancers of the mucosal surfaces from the sinuses to the larynx, with around 3900 new cases annually in women and 8600 in men from 2016-2018.
  • A study assessed the teaching on HNC for UK medical students, finding that 23.2% received no education on it, and 54.3% of those who did were taught through large lectures.
  • The majority (87.1%) of respondents felt there should be more focus on HNC in medical training, highlighting concerns about current knowledge and confidence in recognizing symptoms and referral criteria.

Background: Endodontic infections caused by remaining biofilm following disinfection with chemical fluids encourage secondary bacterial infection; hence, employing laser pulses to activate the fluids is advised to improve microbial biofilm clearance. This study investigated the performance of Er,Cr:YSGG laser in photon-induced photoacoustic streaming (PIPS) agitation of 5.25% sodium hypochlorite (NaOCl) to enhance the removal of mature Enterococcus faecalis (E.

Background And Aims: The recent monkeypox (Mpox) outbreak confirmed by the World Health Organization (WHO) underscores the importance of evaluating the knowledge and attitude of medical students toward emerging diseases, given their potential roles as healthcare professionals and sources of public information during outbreaks. This study aimed to assess medical students' knowledge and attitude about Mpox and to identify factors affecting their level of knowledge and attitude in low-income and high-income countries.

Methods: A cross-sectional study was conducted on 11,919 medical students from 27 countries.

Background: There is an ongoing need to identify pathologic prognosticators in early-stage oral cavity squamous cell carcinoma (OCSCC) to aid selection of patients who may benefit from adjuvant treatment. The objective of this study was to evaluate the prognostic ability of worst pattern of invasion-5 (WPOI-5) defined by the presence of satellite nodules, extratumoural perineural invasion (PNI) and/or extratumoural lymphovascular space invasion (LVI) in low-stage, node negative OCSCC.

Methods: This was a retrospective study of 160 patients with T1/T2N0 tumours staged using TNM7 treated surgically.

(1) Background: During 2019, the COVID-19 pandemic was threatening healthcare services and workers, and acquiring immunity was an option to stop or limit the burden of this pandemic. Herd immunity was a top priority worldwide as the virus was spreading rapidly. It was estimated that 67% of the total global population should be immunized against COVID-19 to achieve herd immunity.

New researches suggest that an early feeding approach has a long-term influence on chick growth performance and nutrient metabolism. The present study was designed to determine the effect of early feeding and the time of chickens transferring from the hatchery to the field on broiler chickens' productive performance and carcass traits. Two hundred twenty-five chickens, one-day-old of broiler chickens Ross 308 with a mean live body weight of 45 g, were used and were randomly distributed to five treatments by 45 chickens per treatment with three replicates (15 chickens per replicate).

Background: The removal of porcelain laminate veneers with rotary instruments could be accompanied by microfractures because differentiation of the veneer from the dental structure and resin cement is not a highly selective procedure. This can lead to scratches and overheating of the enamel and patient discomfort. Therefore, this in vitro research aimed to examine the effectiveness of the 2790 nm Er,Cr:YSGG laser utilizing a fractional technique to debond lithium disilicate veneer.

The present study was performed to assess Ni-immobilization and the phytoremediation potential of sunflower by the application of quinoa stalks biochar (QSB) and its magnetic nanocomposite (MQSB). The QSB and MQSB were characterized with FTIR, SEM, EDX, and XRD to get an insight of their surface properties. Three-week-old seedlings of sunflower were transplanted to soil spiked with Ni (0, 15, 30, 60, 90 mg kg), QSB and MQSB (0, 1, and 2%) in the wire house under natural conditions.

Problem Statement: Grinding restorations, such as veneers, with rotary instruments, is the conventional removal approach. It may be accompanied by micro-fractures that affect the adjacent healthy dental structures. Differentiation of the veneer from the dental structure, as well as the resin cement, is not a highly selective procedure when rotary instruments are used.

In vivo, Cytophone has demonstrated the capability for the early diagnosis of cancer, infection, and cardiovascular disorders through photoacoustic detection of circulating disease markers directly in the bloodstream with an unprecedented 1,000-fold improvement in sensitivity. Nevertheless, a Cytophone with higher specificity and portability is urgently needed. Here, we introduce a novel Cytophone platform that integrates a miniature multispectral laser diode array, time-color coding, and high-speed time-resolved signal processing.

Background: Two major changes to the staging of oral cavity squamous cell carcinoma (OCSCC) were adopted in TNM8: (1) depth of invasion is now used for T staging and (2) extranodal extension for N staging. The aim of this study was to evaluate if TNM8 stratifies OCSCC patients more accurately than TNM7 based on overall survival (OS) statistics and hazard discrimination.

Methods: Retrospective study of 297 patients with OCSCC who underwent surgery at our institution.
