The objective of this paper is to discuss and put forward the various diversified roles of cyclin D1 in cancer. Neoplasia is defined by abnormal regulation of the cell cycle. Cyclin D1 could be a protein derived from the PRAD1, CCND1, or bcl-1 sequence on body 11q13 that is concerned in each traditional regulation of the cell cycle and pathologic process. Within the G1 (resting) part of the cell cycle, cyclin D1 in conjunction with its cyclin-dependent enzyme (cyclin-dependent kinase) partner is accountable for transition to the S (DNA synthesis) part by phosphorylating the merchandise of the metastatic tumor sequence (protein retinoblastoma) that then releases transcription factors vital within the initiation of DNA replication. Amplification of the sequence or overexpression of the cyclin D1 releases a cell from its traditional controls and causes transformation to a malignant composition. Analysis of those changes provides vital diagnostic information in oral carcinogenesis and is of prognostic value in several cancers. Data of cyclin D1's role in malignancy at the assorted sites provide a basis on which future treatment directed against this molecule will proceed.
Aim:The study aimed at evaluating the clinical efficacy of articaine over lidocaine in the surgical removal of impacted mandibular third molars.Objective:The objectives were to compare the onset of anesthesia, pain during injection, during the procedure and after the procedure, compare the duration of anesthesia, and need for re-anesthesia.Materials and Methods:A prospective study was conducted on 70 subjects planned for surgical removal of mandibular third molars. Subjects were randomly administered one of two local anesthetics. The anesthetic agent used was unknown for the patient and the observer who performed the measurements.Results:The differences in latency with 4% articaine (56.57 ± 9.8 s) and with 2% lignocaine (88.26 ± 12.87 s), pain during procedure for articaine 1.31 ± 0.87 and for lignocaine 2.60 ± 1.06, pain after procedure was 0.89 ± 0.58 for articaine and 1.31 ± 1.05 for lignocaine, and mean duration of anesthetic effect for articaine was 231 ± 57.15 min and 174.80 ± 37.02 min for lignocaine, which was statistically significant. For re-anesthesia, 6 out of 35 patients needed re-anesthesia at the frequency of 8.57% for articaine and 13 out of 35 patients needed re-anesthesia at a frequency of 18.57% for lignocaine.Conclusion:The results proved that articaine had a significant faster onset of action and longer duration of action when compared to lignocaine. Hence, the pain experienced by the patients during and after the surgical procedure was significantly less. The study was concluded that articaine is a safe alternative to lignocaine, which is potent and effective in minor surgical procedures such as removal of mandibular third molars.
Adenomatoid odontogenic tumor (AOT)-a benign (hamartomatous) lesion of odontogenic origin-is an uncommon tumor which affects young individuals with a female predominance, mainly in the second decade. This lesion is most commonly located in the anterior maxilla and is usually associated with an impacted canine tooth. This is a case report of a 39-year-old female patient presented with a large AOT of the posterior maxilla associated with an impacted second molar – a very rare situation.
USG is a reliable and valuable tool for metastatic lymph node screening in head and neck cancer patients. It is a cheap, noninvasive, easy-to-handle and cost-effective diagnostic method. USG performed better than clinical palpation in detecting cervical metastatic nodes.
The purpose of this study was to analyze mandibular fracture site, relationship of the fracture line to the periodontium, vitality of teeth, displacement of the fracture segments and their implications, and determine whether to retain or remove the teeth in the fracture line. Fifty patients with 62 fractures were involved in this study. An electric pulp tester was used to measure the pulpal response. The degree of fracture displacement and the relationship of the fracture line to the periodontium were evaluated using panoramic radiographs. Fractures of the parasymphysis region constituted a majority of 60.87% in the gross displacement category. Four of 50 patients showed no response presurgically and minimal response postoperatively on pulp vitality testing. Patients with teeth in the fracture line showing no response on pulp vitality testing should be advised extraction to avoid further complications.
Fibrous growths in the gingiva with the histopathological presence of calcifications are a common occurrence in the oral cavity. These lesions can be neoplastic in nature with either odontogenic or non odontogenic origin or they can be reactive lesions. This is a case report of an unusual presentation of peripheral ossifying fibroma , unusual because of its abnormally large size with review of literature.
Aim:The aim of our study was to evaluate the advantages and disadvantages of 3D plating system in the treatment of mandibular fractures.Patients and Methods:20 mandibular fractures in 18 patients at various anatomic locations and were treated by open reduction and internal fixation using 3D plates. All patients were followed at regular intervals of 4th, 8th and 12th weeks respectively. Patients were assessed post-operatively for lingual splay and occlusal stability. The incidence of neurosensory deficit, infection, masticatory difficulty, non-union, malunion was also assessed.Results:A significant reduction in lingual splay (72.2%) and occlusal stability (72.2%) was seen. The overall complication rate was (16.6%) which included two patients who developed post-operative paresthesia of lip, three patients had infection and two cases of masticatory difficulty which later subsided by higher antibiotics and 4 weeks of MMF. No evidence of non-union, malunion was noted.Conclusion:A single 3D 2 mm miniplate with 2 mm × 8 mm screws is a reliable and an effective treatment modality for mandibular fracture.
