Objectives: To evaluate the reliability and quality of YouTube videos focused on coronectomy using DISCERN, Video Information and Quality Index (VIQI), and Global Quality Scale (GQS) tools.

Study design: Two reviewers independently identified 53 videos for final analysis and classified based on their quality and content relevance using DISCERN, VIQI, and GQS.

Results: Most videos were targeted to the general public (81.1%) and uploaded by non-profit organizations or professional doctors (45.3%). The average DISCERN score was 37.31 ± 8.95 (poor quality), the average VIQI score was 9.92 ± 3.29 (fair quality). Longer videos showed higher DISCERN scores (P = 0.036) and received more engagement (likes: P = 0.024; comments: P < 0.001). Non-patient uploaders produced videos with higher VIQI scores (P < 0.001), whereas Patient-uploaded videos generated more comments (P = 0.001). Higher content quality was correlated with higher likes (p = 0.013).

Conclusions: Coronectomy-related YouTube videos generally lack sufficient information and reliability. Videos by professionals were higher in quality, whereas those by patients generated more engagement. High-content videos showed superior quality and popularity, but were limited in number. Dental professionals need to improve accessible educational content, influencing patient acceptance of this surgical alternative.

Introduction: Elective neck dissection (END) has become a standard procedure in contemporary clinical practice for patients with node-negative oral cancer, offering a notable improvement in overall survival for early-stage disease. Despite advancements, the 5-year survival rate remains stable, and regional recurrence, albeit infrequent, poses a significant challenge.

Materials and methods: This retrospective single-centre study aimed to evaluate the echelon node in patients with the pathologically node-negative disease who experienced regional and distant failures. Serial step sectioning (SSS) was utilized to identify occult metastasis features, including Isolated Tumor Cells (ITC) and micrometastases (miMets).

Results: Clinical and pathological characteristics of 96 patients were analyzed, revealing significant associations between adverse pathological features like LVI, PNI, DOI, and nodal recurrence. While no micrometastases were detected in this analysis, further investigation with a larger cohort may be warranted.

Conclusions: The study underscores the importance of meticulous pathological assessment and the potential role of adjuvant therapy in mitigating recurrence risks in node-negative oral cancer patients. Additionally, it highlights the need for standardized reporting protocols and adequate lymph node yield in neck dissection procedures to optimize patient outcomes.

Objective: This prospective, randomized, split-mouth, single-blinded clinical study compared the efficacy of simvastatin and melatonin in promoting alveolar bone regeneration and postoperative healing after mandibular third molar extraction.

Methods: Thirty healthy patients undergoing bilateral mandibular third molar extractions were recruited. Simvastatin (10 mg) was applied to one extraction site, and melatonin (3 mg) to the contralateral site using a gelatin sponge carrier. Pain, soft tissue healing, and bone regeneration were evaluated using the visual analog scale (VAS), Landry's Healing Index, and grayscale histogram analysis of digital radiographs over 12 weeks.

Results: Simvastatin-treated sockets demonstrated significantly higher grayscale values at weeks 1 (P < 0.001) and 4 (P = 0.009), indicating enhanced bone regeneration. VAS pain scores were also significantly lower in the simvastatin group at week 1 (P = 0.004). No significant differences were observed in soft tissue healing.

Conclusion: Simvastatin demonstrated superior early osteogenic potential and pain reduction compared to melatonin in third molar extraction sockets. Its accessibility and cost-effectiveness support its clinical utility in socket preservation.

Purpose: A varied list of reasons for lingual hematoma is listed in literature. These are allergic reaction, post-traumatic, spontaneous in patients on anticoagulants or antiplatelets, viral or bacterial infections, self-inflicted injuries, tongue bite during seizures, child abuse and iatrogenic. In the present review, the authors have concentrated on post-traumatic lingual hematoma and its management.

Material and methods: The authors have systematically searched the literature reporting post-traumatic lingual hematoma following the PRISMA guidelines. The search was performed in PubMed, Google Scholar, Semantic Scholar and the Cochrane library database from 1985 to 2023.

Results: 38 studies {41 patients (27 males and 14 females)} were included and analyzed in the present systematic review. All patients, except 2 (succumbs due to their medical condition), reported complete resolution of hematoma. The age range was 70 days-79 years. In all the reported studies, the airway was managed with either intubation and/or tracheostomy. Treatment varied from only observation, airway maintenance (intubation/tracheostomy), steroids administration, antibiotic coverage, reversal of antiplatelet or anticoagulant drugs, embolization or surgical intervention.

Conclusion: Prompt recognition and management of the airway are the crucial step in these patients. Acute lingual hematoma is a clinical diagnosis, and to prevent related complications, a detailed history of preexisting comorbidities and medication is crucial. Most importantly, repeated examination of oral cavity in case of lingual hematoma is mandatory.

Background: Present study has compared local anaesthetic efficacy of two agents, 5% tramadol with adrenaline 1:80,000 and 2% lignocaine with adrenaline 1:80,000 for bilateral maxillary premolar extraction under supra-periosteal injection.

Materials and methods: This prospective, split-mouth, double-blinded, randomised, clinical study was conducted on 69 patients requiring extraction of maxillary premolars bilaterally for orthodontic reasons. The study group received 5% tramadol hydrochloride, and the control group received 2% lignocaine hydrochloride. Parameters evaluated were pain on injection, onset and duration of anaesthesia, and post-extraction analgesia.

Results: Current study observed longer duration of anaesthesia for lignocaine than that of tramadol, p < 0.001. Lesser perception of post-extraction pain and longer duration of analgesia was observed on tramadol side compared to lignocaine, p = 0.001. Consumption of analgesic tablets was more in lignocaine group, p = 0.022.

Conclusion: Tramadol can be safely employed as an alternative to conventional local anaesthetic agents through supra-periosteal injection due to its dual local anaesthetic and analgesic action.

Materials and methods: Patients satisfying the inclusion and exclusion criteria underwent arch bar application followed by either closed reduction or open reduction with internal fixation. Pre-operatively: OHI, GI, radiographically displacement, no. of fractures, Perioperatively: Duration of procedure, glove perforation, wire prick injuries, screw loosening/wire breakage, stability, and comfort intraoperatively. Postoperatively: OHI index and GI index, screw loosening/wire breakage, arch bar removal time and glove perforation, wire stick injury, root perforation. Chi-square test was used for categorical data in tabular and graphical forms.

Results: A statistically significant difference was observed in the postoperative OHI score, GI score, mean placement time, and mean removal time between Group A and Group B. The stability of the arch bar was matched between the groups. Screw loosening was non significant, Glove perforation was significant between Group A and B. Wire stick injury was non-significant between group A and B.

Conclusion: The Hybrid Arch Bar proved to be superior to Erich's Arch Bar in terms of time efficiency, stability, comfort, and oral hygiene. Overall, the benefits of the Hybrid Arch Bar outweigh its disadvantages.

Purpose: Patients with skeletal malocclusions undergo orthognathic surgery to achieve a superior facial esthetic profile. However, stable occlusion following orthognathic surgery is also paramount. This study was thus designed to conduct a functional analysis of occlusion, in terms of relative distribution of bite force in patients who underwent bi-jaw orthognathic surgeries using a T-Scan device.

Materials and methods: A prospective study was carried out on 40 patients between the age group of 18-32 years having skeletal malocclusions requiring bi-jaw orthognathic surgeries. The relative difference in bite force between the right and left side was measured using a T-Scan pre-operatively and at third month post-operatively. The data were analyzed statistically.

Results: The study included 40 patients (14 males and 26 females) with a mean age of 22.7 years. The mean difference in bite force pre-operatively was 27.95% and reduced post-operatively to 16.85%.

Conclusion: The significant decrease in the relative bite force between the left and right side post-operatively implies an improved balance of occlusal load between the two sides and hence a more balanced occlusion post-orthognathic surgery.

Background: This systematic review aims to shed some light on the expression of the EBV-associated LMP-1 oncoprotein and its association with oral squamous cell carcinoma and potentially malignant oral disorder.

Method: An extensive literature search was done in databases including PubMed, Google Scholar, Scopus, ScienceDirect, ProQuest, Cochrane, and Web of Science using the keywords "EBV-associated LMP1 in oral squamous cell carcinoma and oral potentially malignant disorders" for case-controlled studies in English.

Results: The extracted data gathered 21 studies with 1,138 OSCC cases and 448 OPMD cases, out of which 9 studies were eligible for the meta-analysis to determine the association between OSCC and LMP-1, with a total of 444 OSCC cases and 313 controls, and 6 studies were eligible for the meta-analysis to find the association between OPMD and LMP-1, with a total of 367 cases of OPMD and 158 cases of control. After gathering and tabulating the data in Microsoft Excel, the JBI tool was used to analyze the bias risk. The pooled data showed a positive association between EBV LMP-1, OSCC, and OPMD.

Conclusion: The collected data confirm that EBV LMP-1 plays a role in the progression of OSCC and OPMD. Extended research regarding the initiation and progression patterns needs to be further evaluated, which might help in the prognosis.

Objectives: Facial artery aneurysms are rare vascular anomalies that may manifest as pseudoaneurysms following trauma or iatrogenic injury or as true aneurysms due to vascular degeneration. This systematic review aims to summarize the available evidence on the diagnosis, management, and complications of these lesions to guide clinical decision-making.

Methods: A comprehensive search of PubMed, Scopus, and Web of Science was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant case reports, case series, and observational studies published up to October 2024 were included. Data extraction focused on patient demographics, aneurysm characteristics, diagnostic modalities, treatment approaches, and clinical outcomes.

Results: Seventy studies reporting on 74 patients with a mean age of 35 years met the inclusion criteria. Iatrogenic events, particularly post-tonsillectomy, accounted for approximately 39% of cases, while trauma was responsible for 36%. Pseudoaneurysms constituted the majority of lesions. Treatment strategies included surgical removal, endovascular embolization, combined techniques, and conservative management. Surgical intervention demonstrated a high success rate with minimal complications (3.8% complication rate), whereas endovascular procedures were associated with a higher incidence of adverse events (21.4% complication rate), including embolic events and coil extrusion. No standardized management approach was identified, highlighting the need for individualized treatment decisions based on lesion size, location, and patient-specific factors.

Conclusions: Facial artery aneurysms, though rare, require timely diagnosis and tailored management strategies. Surgical intervention appears to offer a favorable outcome with fewer complications compared to endovascular techniques. However, the findings are limited by the reliance on case reports and small sample sizes, which may introduce selection and publication bias. Clinical implications include the need for careful risk-benefit assessment when selecting endovascular approaches. Future large-scale observational studies or trials are needed to establish standardized guidelines.

Background: Nasopalatine duct cyst (NPDC) is the most common non-odontogenic cyst of the oral and maxillofacial region. It arises from the epithelial remnants of the nasopalatine duct. Despite its prevalence, the clinicopathological features of NPDC remain underreported. The study aimed to evaluate the clinicopathological features of NPDC, including clinical presentation, radiological findings, and histological aspects, in a retrospective cohort of patients treated at a single institution.

Methodology: A retrospective analysis was conducted using clinical records of patients diagnosed with NPDC between 2007 and 2024 after seeking clearance from the institutional ethical clearance board. Data collected included age, gender, clinical presentation (symptoms and size), location, radiological findings, and histopathological characteristics.

Results: Ten cases of NPDC were identified, with a prevalence of 0.15%. The mean age of patients was 32 years, with a higher incidence observed in male patients. The most common presenting symptoms were pain and swelling. Radiologically, all the NPDCs were located in the midline of the anterior maxilla, presenting as a well-defined radiolucent lesion. Histopathological examination revealed a diverse pattern across the cases.

Conclusion: This study provides a comprehensive analysis of the clinicopathological features of NPDC, highlighting the importance of early diagnosis and appropriate management. NPDCs typically present with non-specific symptoms and can be effectively diagnosed through radiological and histological examination.
