Purpose: This study aimed to evaluate the masticatory forces in patients treated for mandibular fractures. To assess the magnitude of damage to the masticatory system caused by the various mandibular fractures and the period required for their normalization.Materials and Methods: Data were recorded from the authentic and original bite force measurement device from 2015 to 2017. The sample was composed of 30 isolated mandible fractures patients, Group 1 consisting 15 patients with unilateral mandible fractures, Group 2 consisting 15 patients with bilateral mandible fractures, treated with ORIF (open reduction immobilization fixation) under general anesthesia, and Group 3 was a control group. Predictor variables were drawn from predefined intervals for three months (ninth POW) postoperative week.The condition of wound healing was checked, and masticatory forces are measured at the first, fourth, sixth, and ninth postoperative weeks and compared with a control group of the same age and gender. The outcome variables were the success rate and associated complications.Results: For the study, a total of 30 patients with 15 bilateral and 15 unilateral isolated mandibular fractures were included. The study result suggests that the patient had lower bite forces relative to the control group at all intervals. All patients showed a significant increase in the bite force values from the first to the fourth postoperative weeks (p = ‹0.001), which also increased significantly from the fourth to sixth postoperative weeks (p = ‹0.001), and from the sixth to the ninth week. Conclusion:Based on the results obtained from our study, we conclude that there is a temporary adverse effect on masticatory forces. Fracture of the bilateral mandible has a stronger influence on bite force than unilateral mandible fracture. These fractures also take a longer time to normalize.

Aim: The present study was study to observe incidence of cemental malformations related to mandibular molar roots. Materials and Methods: All cases requiring radiographs of mandibular molars reporting to author during 2011–2019 were included in this study. Mandibular molars had been observed for any radiographic malformations. Any such alterations were noted. Results: Author has screened about 522 intraoral periapical radiographs in this study. A total of 63 cases of root malformations reported with two cases of cementoma were observed in this study. Both these cases were diagnosed as benign cementoblastoma (BC) on excisional biopsy. Conclusion: In this study, we have observed that incidence of cemental malformations is 1.2% and of BC is 0.38% as compared to overall incidence of 1%–6% in Western Maharashtra.

Laser is produced by emission of intense light beam from light source. It is a monochromatic and intense beam of light emitted as a radiation from a light source. The word "LASER" represents "Light Amplification by Stimulated Emission of Radiation" [1-4,6]. Laser is an office-based procedure. It is a small and portable device as well as its manipulation is very easy. Hence, Laser application has gained popularity among dental practitioners [7]. Various types of lasers are used in the field of Oral and Maxillofacial Surgery. Lasers like CO 2 lasers, Nd: YAG, Diode lasers, Er: YAG and Cr: YSGG are used for treating various oral pathologies [4]. In the field of Oral and Maxillofacial Surgery, lasers are having wide applications and they prove beneficial too. Lasers can be used for treating oral mucosal lesions, oral leukoplakia, Lichen planus, gingival melanin pigmentation, Fordyce granules, Oral dysplasia, Premalignant lesions, Oral melanoma, pre-prosthetic surgeries. Lasers can also be used for the management of benign lesions like Mucocele, Ranula, Pyogenic granuloma, gingival hyperplastic lesions, Epulis fissuratum, Lymphangioma, Hemangioma and oral cavity cancers. Laser application is also useful in various surgeries like excisional biopsy, management of venous malformations, Osteonecrosis of jaws, Endodontic surgeries, Fireroom. Lasers are also beneficial for treating ankyloglossia and complications after the extraction of impacted third molars. Laser can also be use in temporomandibular joint (TMJ) surgeries and dental implantology. Laser application is having various advantages like, minimal trauma, decreased postoperative swelling, improved tissue healing [6-10]. Lasers are having very much varied and beneficial applications in the field of Oral and Maxillofacial Surgery. And its important for every dental practitioner and Oral and Maxillofacial surgeon to master the technique of lasers [3-5].
