Unlabelled: The amount of residual dentin thickness and tooth position in the dental arch is crucial to determine whether an intraradicular post should be used. This study aimed to compare stress distribution on the root dentin of an endodontically treated tooth rehabilitated with CAD/CAM milled glass fiber posts (MP), cast metal posts (CMP), or prefabricated posts (PP) with or without ferrule support, using the finite element method.

Materials And Methods: A human upper central incisor was selected, scanned, and treated endodontically.

Aims: Chronic periodontitis is the sixth most prevalent disease worldwide and the leading cause of tooth loss in adults. With growing attention on the role of inflammatory and immune responses in its pathogenesis, there is an urgent need to evaluate host-modulatory agents. Non-steroidal anti-inflammatory drugs (NSAIDs) drugs play a crucial role in managing inflammatory conditions.

Article Synopsis
  • The study aimed to identify radiographic and clinical characteristics of post-traumatic transient apical breakdown (TAB) in luxated permanent teeth, using data from 56 patients treated over 31 years.
  • Analysis of 89 teeth showed that upper central incisors were most affected, with common injuries being extrusion and lateral luxation; TAB was characterized by changes in the periodontal ligament and root resorption.
  • The time for TAB to appear was generally around 3.2 months, with significant differences based on TAB patterns, and the average duration for regression was 9.1 months following the trauma.

  • The study examined the oral health issues in individuals with rare genetic conditions affecting skeletal development compared to those without such diseases.
  • It involved 210 participants aged 2 to 54, with half having conditions like mucopolysaccharidosis (MPS) and osteogenesis imperfecta (OI), and the other half being healthy individuals recruited from similar locations in Brazil.
  • Results indicated that those with rare diseases were significantly more likely to experience dental problems, being 12.9 times more likely to have oral issues than their counterparts without rare conditions.

Article Synopsis
  • Obesity is a complex condition linked to excessive fat accumulation, especially in the abdominal area, which can harm health by increasing inflammation.
  • This study focused on 12 sedentary, overweight, and obese young men and assessed the effects of one strength training session on their blood levels of resistin and leptin, two important adipokines.
  • Results showed that the strength training significantly decreased resistin levels one hour post-exercise, while leptin levels remained unchanged, suggesting that exercise may help reduce inflammation and improve insulin resistance in overweight and obese individuals.

Objective: To evaluate the effect of rapid palatal expansion (RPE) using Haas-type expanders on children's oral health-related quality of life (OHRQOL) and compare said effect with that previously reported for the use of Hyrax-type expanders.

Materials And Methods: Forty participants aged 8-10 years with transverse maxillary deficiency were treated using Haas appliances. OHRQOL was measured using the CPQ before RPE, during RPE (T), at the end of RPE (T), and 1 month after appliance removal (T).

Background: Mohs micrographic surgery (MMS) is a well-established technique for the removal of various types of skin cancers. While sterile gloves (SG) are commonly used in skin surgeries such as MMS, additional understanding of their effectiveness compared to nonsterile gloves (NSG) in preventing local infection is required.

Objective: We aimed to perform an updated systematic review and meta-analysis comparing the use of SG with NSG for local infection rate post-MMS and point out cost discrepancies between these 2 scenarios.

Objective: To report and rank orthodontic finishing errors recorded in the clinical phase of the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) examination and correlate pretreatment case complexity with orthodontic treatment outcomes.

Materials And Methods: This single-center cross-sectional survey collected retrospective data from the clinical phase of BBO examinations between 2016 and 2023. The quality of orthodontic clinical outcomes of each case was assessed by means of the Cast-Radiograph Evaluation (CRE), while case complexity was evaluated using the Discrepancy Index (DI), both tools provided by the American Board of Orthodontics.

  • Sleep-related bruxism (SB) is the nighttime grinding or clenching of teeth that involves the central nervous system, and this study aimed to explore its relationship with microarousals and drops in oxygen levels among individuals with sleep apnea.
  • The study analyzed data from 240 participants using polysomnography to measure SB, microarousals (brief EEG changes), and oxyhaemoglobin desaturations during sleep, without relying on self-reports.
  • Results indicated that bruxers experienced more microarousals than non-bruxers, particularly during NREM stage 2 sleep, but the link between SB and significant drops in oxygen levels was not clear; bruxers had an increased risk for microarous

The present text presents partial results of the research "Young people with disability due to gunshot wounds: an exploratory study from the Memorialistic Narratives", which aimed to problematize the effects of violence and criminality in the juvenile sphere by investigating, beyond the increase in mortality and incarceration rates, the transformation of these young people into people with disabilities, specifically, people in wheelchairs. To achieve this goal, we used as a method the Memorialistic Narratives and worked on the categories of exclusion, violence and a body marked by trauma. We will reflect on the case of Guilherme, a poor, marginalized young man with a disability and a wheelchair user due to a gunshot wound.

Purpose: The authors of this study proposed an innovative approach involving the use of Biodentine™ material as an intraorifice barrier in cracked teeth with root extension to promote internal crack sealing, preventing the possibility of microinfiltration and apical crack propagation.

Materials And Methods: The dental records of 11 patients with 12 posterior cracked teeth with root extension were included with a precise protocol performed by a senior endodontist. The treatment protocol included pulp diagnosis, crack identification using a dental operating microscope (DOM), endodontic treatment, placing a Biodentine™ as an intraorifice barrier, and immediate full-coverage restoration.

Article Synopsis
  • Burnout is defined as a syndrome involving emotional exhaustion, cynicism, and decreased effectiveness, often due to long-term job stress, and has been worsened by the COVID-19 pandemic, particularly among healthcare workers in Brazil.
  • A study surveying 143 hospital workers found a high prevalence of burnout at 53.85%, with the 'frenetic' subtype being the most common, where individuals overexert themselves to meet demands at the cost of personal needs.
  • The study highlights the importance of tailored interventions based on burnout subtypes and notes that younger workers (under 51) experience higher burnout levels, indicating a need for preventative measures in the healthcare sector.

SARS-CoV-2 is an enveloped RNA virus that causes severe respiratory illness in humans and animals. It infects cells by binding the Spike protein to the host's angiotensin-converting enzyme 2 (ACE2). The bat is considered the natural host of the virus, and zoonotic transmission is a significant risk and can happen when humans come into close contact with infected animals.

Anthropogenic noise has been related to stress in captive animals; despite this there have been few studies on animal welfare assessment in walk-through zoo enclosures. We aimed to investigate the behavioural effects of noise on a male-female pair of two-toed sloths (), housed in a walk-through enclosure in a zoo in the UK. The animals were filmed for 24 h per day, during three days per week, including days with potential low and high flow of visitors, for three weeks.

Diprosopus is a congenital anomaly in which partial or complete duplication of craniofacial structures occurs. Because it is rare, the mortality rate is high, and information concerning this anomaly is scarce. This study describes a case of human diprosopus in a 9-year-old male individual, who has severe complications associated with the central nervous, cardiovascular, respiratory, and digestive systems.
