Polyetheretherketone (PEEK) is a semi-crystalline thermoplastic polymer which, due to its very high mechanical properties and high chemical resistance, has found application in the automotive, aerospace, chemical, food and medical (biomedical engineering) industries. Owing to the use of additive technologies, particularly the Fused Filament Fabrication (FFF) method, this material is the most widely used plastic to produce skull reconstruction implants, parts of dental implants and orthopedic implants, including spinal, knee and hip implants. PEEK enables the creation of personalized implants, which not only have greater elasticity compared to implants made of metal alloys but also resemble the physical properties of the cortical layer of human bone in terms of their mechanical properties. Therefore, the aim of this article is to characterize polyether ether ketone as an alternative material used in the manufacturing of implants in orthopedics and dentistry. Full article

Background: Burnout syndrome (BS) is an occupational phenomenon resulting from chronic workplace stress that has not been successfully managed. Although there are underlying causes associated with personal attributes, it is generally linked to external factors within the work environment. The aim of the present study was to investigate the impact of lifestyle factors on BS and its dimensions, as well as on suicidal ideation among Spanish professionals dedicated to implant dentistry. Methods: A cross-sectional observational study was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. An electronic survey based on the Maslach Burnout Inventory—Human Services Survey (MBI–HSS) was distributed to members of the Spanish Society of Implants. The data were analysed using descriptive statistical methods. Results: A total of 305 participants (20.9%) responded to the questionnaire. Notably, 10.8% of the professionals reported experiencing suicidal thoughts, a factor significantly associated with the presence of BS. The lifestyle factors associated with BS included the following: not engaging in aerobic exercise for at least 30 min per day (p < 0.05), not having hobbies that facilitate mental disconnection from work (p < 0.001), not following a balanced diet (p < 0.0001), having an insufficient social life (p < 0.0001), and experiencing suicidal ideation (p < 0.01). Conclusions: The surveyed dentists generally reported having healthy lifestyle habits. Nevertheless, one in ten professionals acknowledged having experienced suicidal ideation at some point, highlighting a concerning association with BS. Full article

Background: Genetic polymorphisms in the cyclooxygenase-2 (COX-2) gene may contribute to individual susceptibility to periodontal disease. A meta-analysis assessed the association between three COX-2 single-nucleotide polymorphisms (SNPs) namely, −765 G/C (rs20417), −1195 G/A (rs689466), and 8473 T/C (rs5275), and the risk of CP. Methods: Following the PRISMA 2020 guidelines, we conducted a comprehensive search of five electronic databases and additional sources. The eligible studies were observational (case–control or cohort) with genotypic data comparing individuals with periodontal disease and periodontally healthy controls. Methodological quality was assessed using the Newcastle–Ottawa Scale (NOS), and the certainty of evidence was evaluated via the GRADE framework. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated under dominant genetic models. Results: Seven studies (n = 1467 participants) met the inclusion criteria. No eligible studies evaluated the 8473 T/C SNP. The meta-analysis of the −765 G/C variant revealed a significant association with periodontal disease (OR = 1.61; 95% CI: 1.12–2.32, p = 0.03; I² = 0%). For the −1195 G/A variant, the pooled OR was 1.86 (95% CI: 1.00–3.43, p = 0.05; I² = 35%), suggesting a borderline significant association. The certainty of evidence was graded as moderate for −765 G/C and low for −1195 G/A. Conclusions: The COX-2 −765 G/C polymorphism is significantly associated with increased CP risk, while the −1195 G/A variant shows a potential, though less certain, link. Larger, high-quality studies using standardized classifications are needed to confirm these associations. Full article

Orthodontic treatment demand has surged due to heightened aesthetic concerns and the increased recognition of oral health’s role in overall well-being. This systematic review was conducted by searching across multiple databases (PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar) for observational studies published between January 2000 and April 2024 that assessed personality traits using validated instruments, with inclusion criteria focused on outcomes such as pain perception, treatment attitude, compliance, satisfaction, and quality of life. The results consistently indicate that negative personality traits, particularly high neuroticism, are associated with increased pain perception, lower satisfaction, and reduced compliance. In contrast, positive traits, including extraversion, agreeableness, and conscientiousness, were correlated with improved orthodontic outcomes and more favorable treatment attitudes. Additionally, extraversion and openness were observed to moderate the negative impact of malocclusion severity on oral health-related quality of life. When examining gender, overall differences were minimal; however, some studies indicated that females reported slightly higher pain scores. These findings underscore the multifaceted role of personality by suggesting that psychological profiling should be incorporated into clinical practice. By recognizing individual personality profiles, clinicians can tailor treatment approaches to foster patient-centered care, optimizing orthodontic outcomes and enhancing overall patient satisfaction.
