Background: Sleep is vital, but issues are mounting. Sleep deprivation is dangerous for hospital nurses. This reduces nurse productivity and increases patient-harming medical mistakes. Shift work affects sleep and circadian rhythms; therefore, night shift female nurses' sleep is important. Nurses and patients lose sleep amid disturbances. Objectives: The study examined night-shift female nurses' sleep quality. Methods: A cross-sectional study was conducted in Dhaka Medical College's Physiology Department from January to December 2019 among 160 female nurses aged 24-50 who work night shifts from 8 p.m. to 8 a.m. in In-patient department of Medicine, Surgery, Obstetrics, and Gynecology. Pittsburg Sleep Quality Index and nurse demographics were obtained. After informed consent was signed, the individual was thoroughly questioned and recorded in the predesigned data form. Statistics were done with Excel and SPSS-26. Results: Mean BMI was 23.91 ± 1.64 kg/m², and systolic and diastolic blood pressures were 105.63 ± 11.10 and 69.94 ± 6.68 mmHg, respectively, without statistical significance (p > 0.05). The Pittsburgh Sleep Quality Index (PSQI) components showed significant results (p < 0.001), with mean scores for subjective sleep quality (1.09 ± 0.35), latency (1.95 ± 0.84), duration (1.77 ± 0.72), and additional parameters resulting in a mean global PSQI score of 7.94 ± 1.76. Highest number of respondents were belonging to age group 31–40 and 68.75% were married and in medical wards (42.50%). The lowest sleep quality was seen in Obstetrics & Gynecological wards, with 54 nurses scoring over 5 on the global PSQI (p < 0.001). About 69% of nurses had a PSQI score > 5, suggesting poor sleep quality, associated with age, marital status, and ward type (p < 0.001). Conclusion: Female nurses need sleep hygiene instruction, shift schedule adjustments, and stress management to sleep better. These obstacles affect nurses' well-being and care quality.

Background: Diabetes mellitus (DM) is an endocrine disorder marked by insufficient insulin production, disrupting glucose metabolism and regulation. DM is classified into type I (DM I) and type 2 (DM II). Glycated haemoglobin (Hba1c) is a marker for long-term blood glucose levels. Benign tongue abnormalities (BTAs) associated with (DM II) include the fissured tongue (FT), benign migratory glossitis (BMG), black hairy tongue (BHT), median rhomboid glossitis (MRG), and oral lichen planus (OLP). Aim of the work: This study aimed to determine the prevalence of BTAs among Libyan patients with controlled and uncontrolled DM II. The study also evaluates the potential correlation between BTA and factors such as age and gender. Materials and Method: This study included 426 Libyan patients with DM II. Disease duration and complications were obtained from the patient's medical records. Dependent binary variables (BTAs) and independent variables (age, gender, glycemic control in controlled and uncontrolled DM II) were calculated using IBM-SPSS 26. Result: 77.2% of the 426 patients with type 2 DM exhibited BTAs. FT 96.2% was the most common BTA, followed by MRG 2.1%. BMG 0.9%. BHT 0.6%, and LP 0.3%. 79.3% were glucose-uncontrolled diabetic patients (GUCDPs) and 20.7% were glucose-controlled diabetic patients (GCDPs). Conclusion: BTAs such as FT, MRG, BMG, BHT and LP were the most frequent conditions. BTA have a high prevalence rate in GUCDPs. BTAs are equally observed in both genders.

Artificial Intelligence (AI) is the ability of machines to perform various tasks with smart work that normally requires human intelligence. It is not a new concept as it was introduced back in the 1950s. However, it has not become the practical tool until two decades ago. Artificial intelligence (AI) has obtained large interest and has long past via a transition level from being a pure statistical tool to being one of the main drivers of modern dentistry. In dentistry, the employment of synthetic intelligence continues to be at its start. Many radiographs are used to decide illnesses with the aid of using displaying the whole shape of the enamel and a few dental troubles that cannot be visible at once with the aid of using the human eye. The concepts of AI, including convolutional neural networks and/or synthetic neural networks, have proven a selection of applications in dentistry, forecasting the viability of stem cells. The dental pulp, measuring operating lengths, pinpointing root fractures and periapical lesions and forecasting the achievement of retreatment procedures. AI has established accuracy and precision in detection, evaluation and prediction. Thus, this review narrates the history, classification and its applications in dentistry.

Aim: The present study was carried out to assess the level of knowledge about ionizing radiation hazards among Yemeni patients in Sana’a city, republic of Yemen. Methods: A cross-sectional study of 669 questionnaires which tested patients ’information about ionizing radiation, its’ harmful effects and protection from these effects. This study performed on participants who referred for radiological examinations to the radiology department of two academic hospitals. Results: There is a no significant difference in the level of knowledge between different age groups (p=.058) and gender (p=.179), However, there is a significant difference in the level of knowledge among different educational levels groups and between who work or study in the medical field or not (p=.000). The mean knowledge score was 7.0149 ± 2.12550, which indicate good level of knowledge between study participants. Conclusions: The study indicates a good level of knowledge between a sample of Yemeni population, and to elevated their knowledge to a higher level, the government, ministry of health, and hospitals have a responsibility to educate the population and increase their level of knowledge about ionizing radiation and its harmful effects.

Distalization is a common orthodontic technique used to address Class II malocclusions, particularly those where there is an overjet due to maxillary protrusion. It’s performed to correct average to moderate class 2 malocclusions (<3mm) by retracting the maxillary teeth. This technique should be preferred in patients presenting a class II malocclusion due to maxillary protrusion or in adult patients undergoing compromise treatment. The following case report describes an adult female patient with class II subdivision in the left side treated by clear aligner (invisalign) by distalization and class II elastics. Sequential distalization protocol was used starting with the second molar, once the second molar has moved two-thirds of the desired distance, the first molar is distalized, followed by the premolars and canines. Finally, the four incisors are retracted to complete the treatment.

Aim: To analyze the mental foramen dimensions and location for gender determination in a sample of Yemeni population. Methods: This is a retrospective study performed on 420 maxillofacial CBCT scans, 210 males and 210 females with age ranged from 20 to 60- years old. Osteometric analysis of the dimensions, shape and position of the mental foramen was performed. Results: In comparison between males and females, all mental foramen (MF) measurements were statistically significant except at the distance from the superior mental foramen to the alveolar crest. The all measurements of males were higher than females. MF with round shape was the most common between both males and females. The most common location of the MF was presented below the apices of the 2nd premolars. Conclusions: We can be concluded that the vertical and horizontal dimensions the MF and the distance from the lower border of the MF to the lower border of the mandible exhibits gender dimorphism in the Yemeni population. The shape and horizontal position of the MF do not show any difference denoting that they cannot be used for identification of gender.

Aim of the study: To study salivary immunoglobulin A and lysozyme levels and their relation to dental caries status in a group of Yemeni asthmatic children. Subjects and methods: One hundred children of both genders were enrolled in this study, aged 6-10 years. The cases were divided into two main groups: fifty asthmatic children and fifty healthy children. Every child was examined for dental caries and assessed according to WHO criteria (1997) using defs for primary teeth and DMFS for permanent teeth. Salivary samples were collected from each child in each group and analyzed for sIgA and lysozyme. The relation between them and dental caries status for primary and permanent teeth was evaluated. Results: Results showed that there was no statistically significant difference between gender distributions of asthmatic and healthy children. In addition, there was no statistically significant difference between the mean sIgA levels of both groups. There was a statistically significant difference between asthmatic and healthy children regarding lysozyme levels. This difference in mean lysozyme levels was higher in asthmatic than healthy children. Asthmatic children showed statistically significant differences regarding defs and DMFS scores, which were lower in asthmatics than healthy children. For asthmatic children, there was a statistically significant positive correlation between defs scores and sIgA levels and a statistically significant negative correlation with lysozyme. In asthmatic children, a statistically significant positive correlation existed between DMFS scores and age and sIgA levels. For healthy children, there was a statistically significant positive correlation between DMFS scores and both age and sIgA levels. Conclusion: In children with allergic asthma the salivary concentrations of sIgA and lysozyme were significantly higher and the defs and DMFS scores were lower than in healthy children.

Aim of the study: To assess the attitude and knowledge among Yemeni parents toward their child’s oral health practice and habits with associated factors. Subjects and methods: This study was carried out using three hundred self-administered structured questionnaires for parents or guardians. Demographic variables, knowledge of dental health, oral health, and dietary practices concerning dental care, and attitudes toward oral health were assessed. The correlation between sociodemographic status and oral health knowledge and practice was evaluated. Result: results showed that the mean caregiver's level of knowledge is 53.9%. Most mothers have good knowledge about the age of primary teeth eruption 71.9% and exfoliation 64.9%, the significance of primary teeth 78.4%, what causes the most common dental disease affects teeth 91.8%, and the importance of cleaning teeth 85.4%. 68.4% Cleaned their teeth, and most of them 78.4% remained to encourage their children to clean their teeth. Mothers have bad knowledge about the time to start brushing their children’s teeth 46.8% and the role of fluoride in preventing dental caries 32.2%. There was a statistically significant correlation between the level of knowledge and the mother’s education level and occupation. Conclusion: Yemeni mothers have average knowledge of their children’s oral health status. There was a statistically significant relation between the mother’s education level and the level of knowledge. The mother's education level group (Professional) ranked first with a knowledge level (73%).

Adult patients seeking orthodontic treatment consistently have aesthetic concerns, even throughout the course of the treatment. This has lead to the introduction of Lingual Orthodontics in 1970s by Dr. Craven Kurz of USA and Dr. Kinya Fujita of Japan. Lingual orthodontics, in addition to its aesthetic benefits, offers several other advantages. The cooperation and confidence level of the patient has increased with the invisible appliances. The Anchorage control, indirect bonding and biomechanics is completely different from labial technique. In this article the concept of lingual orthodontics has been highlighted. The article shows a case report with lingual technique treated in the department of orthodontics at Farhat Hached University Hospital.

Aim and Background: This systematic review aimed to investigate the efficacy of photobiomodulation (PBM) on alleviating orthodontic pain. Review Methods: An extensive electronic search for randomized control trials via Medline (via PubMed), The Cochrane Controlled Clinical Trials Register, and Science Direct up to October 15, 2023 was done. Hand searching was performed for relevant journals. Reference articles were retrieved and exported to Zotero software. The risk of bias was assessed using Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2). Results: A total of 8 articles were considered for systematic review. Most of the studies arrived at the consensus that photobiomodulation (PBM) indeed reduces the pain associated with orthodontic treatments. Conclusion: The synthesis of available evidence in our analysis reveals a substantial body of research suggesting a positive effect of PBM on reducing orthodontic pain. However, the existing variations in PBM parameters, and outcome measurements emphasize the necessity for more standardized approaches in future investigations.

The prevalence of oral diseases has escalated to a global scale, warranting acknowledgment as critical public health issues. With an estimated 3.5 billion individuals worldwide affected by oral diseases, the implications extend far beyond mere dental concerns, encompassing the fundamental health, well-being, and socio-economic productivity of billions. Among these, certain demographic subsets, such as pregnant women, school-aged children, adolescents, the elderly, and physically challenged children, stand out as particularly vulnerable groups prone to oral diseases and associated detrimental habits. Notably, personal behaviours including inadequate oral hygiene practices, tobacco use, excessive alcohol consumption, and consumption of nutritionally deficient diets represent modifiable risk factors significantly impacting oral health outcomes within these populations. Addressing these factors requires a multifaceted approach that integrates preventive strategies, education, and targeted interventions tailored to the unique needs and challenges faced by these special groups. The overarching rationale for this literature review stems from the pressing need to comprehensively understand the multifaceted challenges and opportunities surrounding oral health within special groups. By synthesizing existing knowledge, identifying gaps, and critically evaluating current interventions and strategies, this review aims to provide a robust foundation for informed decision-making and evidence-based practices in oral health education and promotion. In this context, the pivotal role of oral health education emerges as a cornerstone in promoting positive health behaviours and fostering sustainable oral health practices. By empowering individuals and communities with knowledge and skills related to oral hygiene, healthy lifestyle choices, and preventive measures, we can affect substantial improvements in oral health outcomes and overall quality of life. Thus, advocating for innovative, culturally sensitive, and cost-effective strategies that prioritize oral health education within social and cultural frameworks becomes imperative. Such approaches not only hold promise for mitigating the burden of oral diseases but also contribute significantly to enhancing broader health outcomes and fostering inclusive, healthier communities.
