Abstract Classroom presentations represent an important aspect of activities that help English as a Second Language learners showcase their language skills, particularly speaking in front of others, and reveal the educational and psychological obstacles and challenges they face in performing these presentations at the best possible level. The study aims to identify the impact of language anxiety on classroom presentations by applying it to English as Foreign Language learners at Gharian University, which helps to investigate the level and type of anxiety that English as a Foreign Language students at the university suffer from during presentations. The study was conducted on various students of different semesters at University. The sample consisted of 100 students of both genders, divided into two groups (45 males and 45 females), during the academic year 2025-2026. The study relied on a questionnaire as the data collection tool, and the collected data was statistically analyzed using SPSS software. The results showed a high level of anxiety about learning English among the participating students for various reasons. A statistically significant inverse relationship was found between the level of English language anxiety among University students and the quality of their classroom presentations. Statistically significant differences were also found in language anxiety levels among students during classroom presentations, while no statistically significant differences were found between gender and anxiety levels in terms of their impact on the quality of classroom presentations. The stuconcluded with recommendations and suggestions to enhance the

Abstract

Periodontal disease is a multifactorial condition characterized by chronic inflammation and progressive destruction of supporting tissues, with significant implications for oral health and systemic well-being. This study investigated the correlation between inflammatory responses and regenerative outcomes in periodontal supporting tissues, emphasizing the role of epigenetic regulation. A mixed methods approach was employed, combining clinical assessments, patient-reported outcomes, and molecular analyses. Spearman correlation analysis revealed strong associations between clinical indicators of inflammation and perceived regenerative improvements, underscoring the interplay between destructive and reparative processes. Demographic and lifestyle factors, including smoking and systemic health conditions, were found to influence variability in responses. Regenerative therapies demonstrated favorable outcomes in terms of clinical attachment gain, alveolar bone support, and patient satisfaction. These findings highlight the importance of integrating epigenetic insights with clinical practice to develop personalized strategies for managing periodontal disease and enhancing tissue regeneration

Abstract

Natural dentin repair is a biologically mediated process that preserves tooth vitality through odontoblast activity and intracellular signaling pathways. This study employed a mixed methods design, combining laboratory experiments with descriptive analytical surveys of dentists in Egypt, to investigate the mechanisms of odontoblast differentiation and assess clinical knowledge and practices related to regenerative dentistry. Laboratory analyses included microscopic and molecular techniques to evaluate cellular signaling during dentin repair, while questionnaires were distributed to 100 dentists across public and private sectors. Data were analyzed using quantitative statistics, qualitative assessments, and integrative interpretation of laboratory and clinical findings. Results revealed significant positive correlations between dentists’ knowledge of intracellular signaling and their clinical practices, with Spearman correlation coefficients ranging from 0.52 to 0.65 (p = 0.01). A majority of respondents (80%) reported experience with mesenchymal stem cell therapy for craniofacial bone remodeling or dental tissue regeneration, and 70% observed improvements in bone density, while 65% reported enhanced dental tissue regeneration. Imaging studies were widely used, with 85% of participants undergoing radiographic or CT evaluations to monitor progress. Despite these encouraging outcomes, only 35% of dentists were familiar with molecular techniques targeting signaling pathways, and just 40% reported applying clinical strategies to enhance odontoblast differentiation. Notably, 75% expressed interest in specialized training to improve their knowledge and practices in regenerative dentistry. The study concludes that while theoretical awareness of dentin repair mechanisms is relatively strong, clinical application remains limited. Bridging this gap through structured training and evidence-based protocols will be essential for integrating molecular insights into routine dental practice, thereby improving dentin repair outcomes and long-term tooth vitality.

ABSTRACT This study investigates the effects of self-assessment on students’ motivation and language proficiency among English Department students at the Faculty of Arts, AL-Assaba. A quantitative research design was adopted, using a questionnaire distributed to a sample of 60 students. The findings indicate that self-assessment plays a significant role in enhancing learners’ motivation, self-awareness, and perceived language proficiency. Most students reported positive attitudes toward self-assessment and felt it Improved their English skills. The study concludes that incorporating self-assessment into English language instruction can foster learner autonomy and Improve learning outcomes. It recommends Integrating self-assessment practices into curricula and providing guidance to students on effective self-assessment.

While most pregnant women in Gharyan city demonstrated adequate oral health knowledge, gaps persist in

preventive practices, particularly regarding fluoride use and dental visits. Education level and dental visits

during pregnancy were significant determinants of knowledge. These findings highlight the need for targeted

oral health education programs and increased access to dental services for pregnant women to improve oral

health outcomes for both mothers and their infants.
