Design, use, and contemporary technological approaches of mouthguards in pediatric athletes
(Harran University, 2025) Kaplan, Ceren; Yoğurucu Değerli, Gizem
Orofacial trauma is a common concern among pediatric athletes, particularly those participating in contact and high impact sports. Due to their developing dentofacial structures, children are more vulnerable to injuries. Mouthguards are intraoral devices designed to absorb and disperse impact forces, playing a critical role in injury prevention. This review outlines the classification of mouthguards, fabrication techniques, and the process of personalized design. It also examines usage trends in children and highlights how awareness among parents and coaches influences adherence. Recent advancements in digital dentistry—especially CAD/CAM systems and 3D printing technologies—have enabled the production of custom-made mouthguards that provide superior fit, comfort, and protection. Studies suggest that individualized mouthguards improve compliance among pediatric athletes and significantly reduce the risk of orofacial trauma. Therefore, technological innovations, combined with increased stakeholder awareness, are believed to enhance the adoption and clinical success of effective protective mouthguards in pediatric sports dentistry.
Are informations of subperiosteal implant procedure on youtube really useful?
(Udruženje stomatologa Balkana, 2025) Özdal Zincir, Özge; Zincir, Ali; Özdal, Umut
Background/Aim: Subperiosteal implant is a type of implant preferred in oral implantology in cases with severe bone deficiency where intraosseous implant application cannot be performed. We evaluated the accuracy of the information by examining YouTube videos containing information on this subject. Material and Methods: In the YouTube video search conducted with the keywords ‘Subperiosteal dental implant’, the first 200 videos were watched and evaluated. 118 videos that didn’t meet the analysis criteria were excluded from evaluation and the remaining 82 videos were analyzed. The usefulness scores of all analyzed videos were determined as ‘poor’, ‘moderate’ and ‘excellent’ according to their information content. For statistical analysis, the Kruskal Wallis and Phi tests were used and the significance coefficient was determined as p<0.05. Results: According to the information content of the videos, the usefulness scores were numbered as poor(0), moderate(1), excellent(2) and the average was found to be 0.51. When the usefulness scores of the videos and their demographic information were compared, it was found that there was a significant difference between the video duration (p=0.002), the number of views (p=0.006) and the number of likes (p=0.003). There is a significant difference between the viewing rate of the videos (p=0.044) according to their usefulness scores. It can be stated that video types differ depending on the target audience (p=0.003). Conclusions: Among the YouTube videos examined, those uploaded by health professionals and health companies have a high educational quality and a high viewing rate. However, the number of such videos aimed at informing patients should be increased.Key words: Dental implant, subperiosteal implant, dental prosthesis, social media.
An examination of the relationship between perceived parental attitudes and test anxiety among 8th grade students
(Recep Kanat, 2025) Noyan, Reyhan; Keçeci, Berra
This study aimed to examine the relationship between perceived parenting styles and test anxiety levels among 8th grade students. The research was designed within the framework of the relational survey model, one of the quantitative research methods, and the sample consisted of 318 students studying in 10 public secondary schools in Eyüpsultan district of Istanbul during the 2024–2025 academic year. Data were collected through the Parental Consent Form, Demographic Information Form, Parental Attitude Scale (PAS), and Westside Test Anxiety Scale (WTAS). The collected data were analyzed using SPSS 25.0, and independent samples t-test, one-way ANOVA, Pearson correlation analysis, and multiple linear regression tests were conducted. The results revealed that female students experienced significantly higher levels of test anxiety compared to male students. Correlation analysis showed significant negative relationships between test anxiety and the dimensions of acceptance-interest and psychological autonomy. Multiple regression analysis indicated that only the psychological autonomy dimension was a significant predictor of test anxiety. No significant differences were found in test anxiety levels according to different types of 3 parental attitudes. These findings demonstrate that students’ test anxiety is significantly associated with the psychological autonomy and acceptance they perceive from their parents. The results are consistent with previous studies in the literature, showing that democratic parenting styles and psychologically supportive approaches have a reducing effect on test anxiety. In this regard, the study contributes to the understanding of psychosocial factors influencing test anxiety. Based on the findings, it can be suggested that strengthening guidance and counseling services, expanding parental awareness programs, and encouraging teachers to collaborate with families are crucial steps in reducing students’ test anxiety. Furthermore, parents adopting approaches that provide greater psychological autonomy and acceptance may help students cope more effectively with test anxiety.
Anatomic safety profile of a novel mini external fixator for proximal crescentic osteotomy in hallux valgus correction: A cadaveric study
(Springer Nature Link, 2026) Coşkun, Osman; Nteli Chatzioglou, Gkionoul; Gürses, İlke Ali; Ok, Fatma; Gayretli, Özcan; Erdil, Mehmet
Purpose The proximal crescentic osteotomy is an effective procedure for hallux valgus correction, but stable fixation remains challenging. Our previous biomechanical study suggested that the MEF may offer comparable or greater stability than a specific cannulated screw fixation construct in a cadaveric model. This study aims to evaluate the anatomical safety of the MEF by investigating its relationship with critical neurovascular structures and tendons. Methods An anatomical dissection study was performed on ten foot cadaveric specimens. The MEF was applied using five mini-Schanz pins inserted in predefined positions. Following fixation, a layer-by-layer dissection was conducted to expose the dorsalis pedis artery, superficial cutanous branches of the foot, the superficial venous arch, and the extensor hallucis lon gus and brevis tendons. The distance from each pin to these structures and any iatrogenic injuries were recorded. Results The superficial venous arch was injured at low rates by the medial distal pin (20%), the medial proximal pin (10%), and the lateral distal pin (20%). Tendon injury was more frequent, with the extensor hallucis longus tendon being injured by 20–30% of pins, and the extensor hallucis brevis tendon by the lateral intermediate and distal pins (20% each). Conclusion The application of the MEF for first metatarsal fixation appears anatomically safe with respect to major arteries and nerves. The consistent avoidance of the dorsalis pedis artery and key sensory nerves is a significant advantage over some established techniques. However, surgeons should be aware of the potential risk to the superficial venous arch and extensor tendons during pin placement. These findings support further investigation of the MEF for proximal crescentic osteotomy f ixation.
Efficient and facile synthesis of hydroxy-functionalized hexagonal boron nitride nanosheets by ion-assisted liquid phase exfoliation method
(Eskişehir Osmangazi University, 2025) Yaman Uzunoğlu, Gülşah
Hexagonal boron nitride (h-BN) nanosheets have attracted significant attention due to their unique mechanical, thermal, and electronic properties. Their biocompatibility, thermal conductivity, chemical stability, and versatility make them indispensable in cutting-edge technologies. Hydroxy-functionalized h-BN nanosheets (h-BNNS-OH) exhibit immense potential in various applications, including electrochemical energy storage, drug delivery systems, and heat spreaders in thermal management systems. This study focuses on the hydrothermally ion-assisted liquid-phase exfoliation of h-BN powder to produce few-layer h BNNS-OH. The exfoliation process involves hydrothermal treatment of bulk h-BN in the presence of concentrated aqueous solution of KOH and NaOH at 180 °C, followed by sonication for dispersion of h-BNNS-OH in water. Characterization of h-BNNSs was performed using powder X-ray diffraction (XRD), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The resulting exfoliated h-BNNSs are hydroxyl-functionalized on their surface. This study demonstrates the effectiveness of the successive execution of the hydrothermal treatment in the presence of excess alkali metal hydroxides and probe sonication as a facile and efficient exfoliation process, resulting in dispersions of h-BNNS-OH in water with remarkably high stability (beyond 9 weeks) and high product yield (17 %) at only one exfoliation cycle.
