All 27 intraoral maxillary defect patients were adequately repaired. After surgery, all patients had a favorable wound healing in their first month of follow-up. The surface changed from the typical fatty yellow to a pale yellow-white color after 3 to 4 days, and all fatty surfaces were covered by newly formed reepithelized mucosa in 3 to 4 weeks. The mouth opening and graft was also satisfactory in 7 patients who received adjuvant radiotherapy for carcinoma. So, we conclude that the use of BFP in intraoral maxillary defects is a clinically effective, convenient, safe, and quick method of repair for small to medium-sized defects.

Introduction: The positional relationship between the mandibularcanal with impacted mandibular third molar is the main factor of inferior alveolar nerve injury. The purpose of this study wasto classify the anatomical three dimensional relationship between the proximity of impacted mandibular third molars to the inferior alveolar canal. Methods: The descriptive cross-sectional study was conducted inthe Department of Oral and Maxillofacial Surgery of a tertiary care hospital from July 2020 to August 2020 after obtaining ethical approval from the Institutional Review Committee (Reference number 2506202001). Cone-beam computed tomography images of 200 patients’ mandibular third molars were used. A convenient sampling method was used. Data were analyzed using Statistical package for the Social Sciences. Results: Mandibular canal relative to the roots of the mandibular third molar was observed on the apical side in 104 (52.0%) and 173 (86.5%) third molars had direct contact with the mandibular canal. About 36 (97.3%) lingually placed mandibular third molars had contact with the mandibular canal. Conclusions: The findings of the study conclude that most of the mandibular third molars situated lingually had a higher occurrence of mandibular nerve involvement. The anatomic structures of the mandibular third molar and the mandibular canal may be helpful to draw upon the adequate surgical plan to avoidor reduce nerve involvement.

This study was conducted to evaluate the feasibility of clinically applying facial submental island flap in reconstruction of oral cancer ablation in residents of Xinjiang, China. A total of 21 patients with oral cavity cancer underwent surgical resection during 4.4 years. Immediate reconstruction with submental island flap was performed and reviewed. The site, stage, pattern of neck dissection, postoperative complication, and the technique of flap transfer were recorded. The patients were followed up to assess the status of the flap, its function, and the oncologic outcomes. Eventually in this study, all patients had undergone neck dissection and wide excision of the primary lesion. The follow-up period ranged from 3 to 52 months. Of 21 patients, 2 patients had complete flap loss. The overall survival rate in our study is found to be 90.4%. The submental island flap is an excellent alternative for reconstruction of intraoral cancer defect because of its function, reliability, versatility, and relative ease of application. However, further study depends upon the long-term follow-up of the patients and oncologically sound neck dissection.

Introduction: Third molar impaction is a common patient complaint in dentistry. Common symptoms are localized pain, swelling, bleeding, and difficulty in mouth opening. Since dental students deal with patients early in their education, for better skill, they should have knowledge of various teeth impactions. Hence, the objective was to find out the knowledge of impacted teeth among undergraduate dental students of a medical college. Methods: A descriptive cross-sectional study was conducted among bachelor in dental surgery students of a medical college from November 30, 2020 to April 3, 2021. Data collection was done by convenience sampling after receiving ethical clearance from Institutional Review Committee (Reference 1208202006). A structured questionnaire in Google Forms was sent to 221 participants via Viber. Out of 213 responses received, 144 were analyzed in Excel after discarding for duplication and other errors. Descriptive statistics such as mean, standard deviation, frequency, and percentage were analyzed. Results: Out of the total of 144 participants, only 81 (56.3%) (47.89-91.4 at 95% Confidence Interval) had known about the term ‘impacted teeth’ before joining Bachelor in Dental Surgery course. The source of information was mostly the internet 27 (18.8%) followed by dentist 23 (16%). Most students 116 (80.6%) were familiar with third molar impactions, 62 (43.1%) knew about types of impacted teeth/impaction, and 100 (69.4%) were aware of the complications of not removing impacted teeth. Conclusions: Dental students should be provided with appropriate ‘impacted teeth’ education supported by practical experience. More detailed information regarding impacted teeth should be included in the curriculum for better understanding.

Introduction: Despite oral cancer being a common cancer in Nepal, little is known about oral potentially malignant disorders which have a high likelihood of malignant transformation. This study aims to find out the prevalence of oral potentially malignant disorders among patients attending the Department of Oral Medicine and Radiology of a tertiary care dental hospital. Methods: A descriptive cross-sectional study was carried out among 611 patients from 14th January, 2021 to 15th July, 2021 at the Department of Oral Medicine and Radiology of a tertiary care centre after receiving ethical clearance from the Institutional Review Committee (Reference number: 2306202002). Convenience sampling was done. Patients aged 18 years and above were enrolled into the study. Follow-up cases and patients requiring emergency treatment were, however, excluded. All demographic data, cancer and dietary history and clinical examinations were recorded. Descriptive analysis was done using Statistical Package for the Social Sciences version 22.0. Point estimate was done at a 95% Confidence Interval for frequency and percentages for binary data. Results: Among 611 total participants, the prevalence of oral potentially malignant disorders was found to be 26 (4.25%) (2.65-5.85 at a 95% Confidence Interval), where males were 19 (73.07%), females were 7 (26.92%), and 23 (88.46%) of them had history of consuming various forms of tobacco, areca nut, and alcohol. Conclusions: The prevalence of oral potentially malignant disorders in this hospital-based study was found to be lower than previous studies conducted in similar settings.
