In recent years, social media platforms have become one of the primary sources of health information for many individuals, including information related to oral and dental health [1,2]. People increasingly rely on platforms such as Facebook, Instagram, TikTok, and YouTube to obtain advice about oral hygiene, dental treatments, and aesthetic dental procedures [2,3]. This growing dependence may contribute to improving oral health awareness and encouraging preventive behaviors; however, it also increases the risk of exposure to inaccurate or non-scientific information, which may negatively influence oral health decisions [1,4]. Therefore, studying the impact of social media on oral health is essential to understanding its role in shaping public knowledge, attitudes, and oral health behaviors

Background: Musculoskeletal disorders (MSDs) are a major global public health concern and a leading cause of disability. Work-related MSDs (WMSDs) are common among healthcare professionals, particularly dentists, due to prolonged static postures, repetitive movements, forceful exertions, and ergonomic challenges. WMSDs can cause pain in the back, neck, shoulders, and wrists, reduce productivity, compromise care quality, and impact mental health. Risk factors include gender, age, years of practice, long working hours, and poor ergonomic practices. While international studies report high prevalence rates among dentists (64–93%), limited data exist on Yemeni dental professionals, who may be further affected by unhealthy lifestyle behaviors. Aim: The objective of present study is primarily to investigate the awareness of ergonomics and prevalence of musculoskeletal disorders among dental professionals and students.Methods:A descriptive cross-sectional study was conducted among 200 dentists at Al-Rashid University in Sana’a City, Yemen, using a self-administered questionnaire. Participants were selected through convenience sampling and provided informed consent. Data were analyzed using SPSS version 27 with descriptive statistics, including frequencies, percentages, means, and standard deviations, at a significance level of p < 0.05.Results:Among 200 participants, most were aged 20–24 years (56%), female (80%), undergraduate students or general dentists (79.5%), with less than 5 years of experience (78.5%) and practicing in dental colleges (71%). Over half worked less than 4 hours daily (51%) and 4–5 days weekly (57%), and only 50.5% took work breaks.Neck (78.3%), lower back (69.2%), and shoulder pain (61.1%) were the most common symptoms. Most participants reported moderate pain (76%), which negatively affected work performance in 55.5%. Pain severity was significantly associated with reduced work performance (p < 0.001), while no associations were found with demographic, professional, work-related, or ergonomic factors (p > 0.05). Regular physical exercise was significantly associated with lower pain severity (p = 0.041). Long working hours (29.5%), awkward posture (28.5%), and work-related stress (25.5%) were the most commonly perceived contributing factors.Conclusion: Work-related musculoskeletal disorders are common among dentists and dental students in Sana’a City, Yemen, particularly affecting the neck, lower back, and shoulders, and are associated with reduced work performance. Regular physical exercise appears to have a protective effect, highlighting the need for ergonomic and preventive interventions in dental practice.

Background: Oral health is an essential component of overall health and well-being and plays a major role in public health. Dental anxiety refers to a feeling of fear or apprehension about dental treatment, often accompanied by a sense of loss of control. Objective: To assess the prevalence of dental anxiety among university students. Method: The study is cross sectional, the population of our study, University of science and technology at alqahera Street, southern west of Sana’a, Yemen. Alrasheed smart university at alkamseen street northern west of Sana’a, Yemen. , Sample was Non probability sampling method, convenient method, we used the questionnaires as tools for the study that consisted 20 Questions we used for questionnaires for from previous study. We used SPSS for data entry and data analysis Results: Among the 100 participants, most were aged 20–24 years (67%), with 51% males. The majority were single (81%) and had a moderate-income level (68%). Oral health problems were common, including dental pain (61%), bleeding gums (59%), and dental calculus (62%). Overall, 61% of participants experienced dental anxiety, which was lowest before a dental visit and highest during clinical procedures, particularly when seeing dental injections and hearing the dental drill.

Background: The temporomandibular joint (TMJ) is a complex joint essential for mastication and speech and is prone to functional and pathological disorders. Temporomandibular disorders (TMD) are characterized by pain and/or functional limitations affecting the TMJ, masticatory muscles, and related structures, with symptoms including pain, joint sounds, restricted movement, and headaches. TMD has a multifactorial etiology involving behavioral, parafunctional, and psychological factors. Psychological stress and anxiety play a key role in increasing muscle activity and parafunctional habits, contributing to TMD development. University students, particularly dental students, are at increased risk due to academic and clinical stress. However, data on TMD prevalence and its psychosocial associations among dental students in Yemen are limited. Therefore, this study aims to assess TMD prevalence among dental students in Sana’a and examine its association with psychological stress, anxiety, parafunctional habits, sleep patterns, and selected demographic factors. Methodology: Descriptive cross-sectional study was conducted on January 8, 2024, at Al-Hikma University and Al-Rasheed Smart University in Sana’a, Yemen, to evaluate the impact of dental students. The study included 100 undergraduate students (50 from each university) selected by simple random sampling. Data were collected using a self-administered structured questionnaire covering demographic characteristics, TMJ pain, TMD-related symptoms, , functional impact, quality of life, and health awareness. Pain severity was assessed using a numerical rating scale (0–10), and stress and anxiety using a five-point Likert scale. Participation was voluntary with informed consent, and confidentiality was ensured. Data were analyzed using SPSS version 27. Descriptive and inferential statistical analyses were performed, including Chi-square tests, Spearman’s correlation, t-tests or non-parametric equivalents, and logistic regression. A p-value < 0.05 was considered statistically significant. Results: Among 100 dental students, 71% reported TMJ pain, mostly mild or moderate, intermittent, and short in duration. Joint clicking (44%) and pain during yawning (32%) or chewing (27%) were common. Parafunctional habits—night bruxism (32%), stress-induced clenching (68%), and masticatory muscle fatigue (55%)—were prevalent, with night bruxism and muscle/occlusal changes significantly associated with TMJ pain (p ≤ 0.007). High academic stress (67%) and anxiety (56%) correlated with TMD severity (r = 0.524, p < 0.001), while sleep patterns were not significant. TMJ pain impaired concentration (44%) and eating (35%) (p = 0.004). Gender influenced anxiety and TMJ pain, whereas age, academic year, university, and study hours showed minimal impact. Conclusion: Temporomandibular disorder symptoms are highly prevalent among dental students, mainly mild to moderate in intensity. Psychological stress, anxiety, and parafunctional habits—especially night bruxism and masticatory muscle fatigue—are major contributors to TMJ pain, while sleep factors have minimal impact. These results underscore stress as a key determinant of TMJ health.
