Molar intrusion has always been a complex and difficult treatment modality. It can be approached for treating open bite patients or over erupted molar tooth/teeth. Through the decades, various treatment strategies have been developed to intrude molar teeth, ranging from non-surgical to surgical approaches, and utilizing various appliances, some which rely on patient compliance. The aim of this article is to compile and summarize the existing molar intrusive techniques and appliances with respect to their advantages and disadvantages, and their possible clinical effectiveness.

It has been reported that lipopolysaccharide ( LPS) has the ability to induce inflammation and osteoclastogenesis. Osteoclast formation is dependent on macrophage-colony-stimulating factor ( M- CSF) and ligand for the receptor activator of necrosis factor- kB. In this study, the effect of antibody against c- Fms, which is the receptor of M- CSF, on LPS-mediated osteoclastogenesis was investigated in mice. LPS was administered with or without anti-c- Fms antibody into the supracalvaria of mice. The number of osteoclasts and the levels of mRNA for cathepsin K and tartrate-resistant acid phosphatase, which are osteoclast markers, in mice administered both LPS and anti-c- Fms antibody were lower than those in mice administered LPS alone. The level of tartrate-resistant acid phosphatase 5b as a marker of bone resorption in mice administered both LPS and anti-c- Fms antibody was also lower. Furthermore, the expression of the receptor activator of necrosis factor- kB, which is receptor activator of nuclear factor kappa- B ligand, was increased upon LPS administration, but the expression was inhibited by anti-c- Fms antibody. These results showed that anti-c- Fms antibody inhibits LPS-induced osteoclast formation. In conclusion, M- CSF and its receptor are potential therapeutic targets in bacterial infection-induced osteoclastogenesis, and anti-c- Fms antibody might be useful for inhibition of bacterial infection-induced bone destruction.

Objectives: To assess the content of YouTube videos on the management of orthodontic emergencies during the COVID-19 pandemic., Materials and Methods: YouTube was systematically searched using the keywords "orthodontic emergency," "orthodontic homecare," "braces emergency," and "braces homecare." The first 100 videos for each keyword were assessed. The upload source, number of views, likes and dislikes, duration, and global quality score were extracted. Home and clinical advice reliability was evaluated using the reliability score (DISCERN) according to the COVID-19 orthodontic emergencies protocol published by the British Orthodontic Society., Results: The majority of the videos were found to be poor quality. Home care advice showed higher reliability than clinical advice. Orthodontic emergency videos uploaded by healthcare professionals had higher reliability., Conclusion: Many types of orthodontic emergencies have received little attention on YouTube, and more useful and reliable educational videos should be uploaded in the event of future pandemics., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Orthodontic Science.)

Introduction: Dental schools have a primary responsibility to devise a curriculum that enhances students' confidence and knowledge in orthodontic case analysis. This study aims to compare the confidence levels and performance of undergraduate students in orthodontic case screening, moderated by faculty in a lecture-based format against their self-analysis of the same cases 1 year later, using a case-based and flipped learning approach., Materials and Methods: This study involved 100 fifth-year students. The same group received predoctoral orthodontics training through an instructor-centered, didactic approach in their fifth year and a case-based, student-centered, flipped classroom approach in their sixth year. At the end of each semester, the students completed an orthodontic case analysis and a self-reflection survey., Results: This study found no significant differences in diagnostic capabilities for orthodontic findings between the two methods studied. However, the self-evaluation survey data revealed an increase in students' confidence levels. This was specifically in terms of carrying out independent orthodontic case diagnosis, effectively communicating with orthodontic specialists, and their comfort in approaching orthodontic cases following the flipped classroom approach. Despite increased confidence in case diagnosis, the results showed that final-year students are uncertain about creating initial treatment plans and referring cases at an early stage., Conclusion: Despite no observed improvement in students' orthodontic diagnostic abilities after another semester of student-centered learning, their confidence in diagnosing orthodontic cases was notably enhanced., (© 2024 American Dental Education Association.)

Aim: This retrospective study aimed to compare and evaluate the pattern of maxillary canine impaction and its association with other anomalies using cone-beam computed tomography (CBCT)., Methods: A total of 59 CBCT records of patients (ages 12 and up) were divided into two groups: A total of 35 subjects with unilateral canine impactions and 24 subjects with bilateral canine impactions. The CBCT data were analyzed for the measurement of qualitative and quantitative variables., Results: In unilateral canine impaction, the mesiodistal (MD) width of the central incisors and the nasal cavity (NC) width were wider ( p < 0.05). The canine-palatal plane (U3-PP) distance was significantly longer in bilateral canine impaction ( p < 0.05). The distance of the impacted canines from the palatal and mid-sagittal planes, the anterior dental arch width, and the maxillary skeletal width changed significantly with the position of the impacted canines ( p < 0.05). Males had 0.185 odds of presenting with a bilateral canine impaction as compared to females ( p = 0.025). The odds of having bilateral canine impaction with a longer canine-midsagittal plane (U3-MSP) distance was 1.30 ( p = 0.003)., Conclusion: The findings indicate a gender predilection with females showing a greater prevalence of bilateral canine impaction. Supernumerary teeth were associated with unilateral impacted canines and lower canine impaction with bilaterally impacted canines., Clinical Significance: Anomalies in the form of the maxillary central and lateral incisors, distance from the maxillary canine to the palatal plane and the mid-sagittal plane, NC width, maxillary skeletal width, and gender, are the best discriminating parameters between unilateral and bilateral canine impactions.

Aim: The study aimed to explore the role, impact, and influence of social media on the population during the coronavirus disease-2019 (COVID-19)pandemic., Background: During pandemics, communication is an important factor to disseminate the information, create awareness and provide timely updates from authorized personnel to the masses. Social media progressed to function as a mediator of transmission of information between the government and authorities and the public during the COVID-19., Review Results: Though several strengths were observed yet liabilities did not go unnoticed regarding the role essayed by social media during this pandemic period. When used responsibly, these technologies can aid in the rapid dissemination of crucial facts, important scientific discoveries, and information regarding diagnosis, treatment, and follow-up as well as comparing different strategies across the world. It is recommended to follow certain fundamental standards while exchanging information on social media networks during the COVID-19 era in order to utilize these technologies responsibly and effectively., Conclusion: In this research, we have made an attempt to synthesize the vital facts regarding the impact, benefits, and drawbacks of using social media during COVID-19. Eventually, the decision of evaluation, acceptance, and denial of the information received rests with the individual., Clinical Significance: Social media use has become intangible with health care. Instead of venturing out the negative effects, we need to focus on utilizing social media for the betterment of the public and to the advantage of the public to increase awareness levels, spread knowledge, and cooperate to tap the benefits to the maximum extent possible to prevent the disease spread.

Purpose: Preschool children with early childhood caries (ECC) frequently exhibit extreme dental anxiety and fear, posing a considerable challenge to paediatric dentists for their treatment. The aim of this study was to evaluate the influence of silver diamine fluoride (SDF) treatment on the oral health-related quality of life (OHRQoL) of uncooperative preschool children using an Arabic version of the Early Childhood Oral Health Impact Scale (A-ECOHIS)., Materials and Methods: A pre-validated A-ECOHIS was used to assess the sensitivity and responsiveness. Fiftyone children, uncooperative with conventional dental care, underwent SDF treatment; their mothers answered the A-ECOHIS before and 4 weeks after treatment. Based on the global transition rating (GTR), the mothers rated their child's oral health condition following SDF treatment., Results: SDF effectively arrested caries after 4 weeks in all children. There was a statistically significant reduction in mean scores of the total A-ECOHIS, child impact scale and family impact scores at follow-up (Wilcoxon signedrank test; p ˂ 0.001). There were statistically significant changes in the mean GTR of children's oral health., Conclusions: A-ECOHIS was sensitive and responsive to SDF treatment. SDF statistically significantly improved the OHRQoL of uncooperative preschool children.
