Benign fibrous histiocytomas (BFHs) are neoplasms of the soft tissue and bone composed of fibroblastic and histiocytic additives without any nuclear pleomorphism or histological anaplasia. It especially occurs inside the skin of extremities, rarely occurs in bone, and may affect the femur, tibia, and pelvic bone. Only a few cases are suggested with the involvement of BFH within the oral cavity. Here we report a case of BFH of the oral cavity localized in the upper right posterior tooth region.

Background: Gender determination by skeletal relies predominantly on the skeletal radiology. Foramen magnum is in a favorable anatomic position, protected by soft tissue and skeleton of the head protecting the area for forensic examination. Foramen magnum being a relatively indestructible structure becomes an important tool in identification of gender. Objective: To study the vagueness and reliability of the foramen magnum (FM) in gender classification through the use of reconstructed computed tomography (CT) images. Materials and Method: A total of 200 patients (100 males and 100 females; age range, 18–60 years) were selected for the study. The FM measurements (sagittal, transverse, circumference, and area) were obtained from reformatted axial sections using a CT scan. Results: It was found that the mean FM sagittal diameter was 35.09 ± 2.48 mm, the FM transverse diameter was 28.76 ± 2.82 mm, the FM circumference was 110.56 ± 8.84 mm, and the FM area was 746.20 ± 108.47 mm2. According to Student's t-test results, in all measured parameters, there was a significant difference between the genders (P < 0.001). Conclusion: In all of the measured variables, there is a statistically significant difference present in the mean values of various parameters between both genders, with males having higher dimensions than female, indicative of sexual dimorphism.

Aim: To analyze the occurrence and correlation of oral manifestations of patients affected by gastro-esophageal reflux disease (GERD), especially with dental erosion. Materials and Methods: With a simple randomization method, a total of 120 patients, GERD-diagnosed patients (group 1, n = 60), based on complaints and reviewed by gastroenterologists through proper history, clinical pictures, and established investigations, and healthy individuals (group 2, n = 60), were enrolled in the study. Oral manifestations such as xerostomia, oral acid/burning sensation, subjective halitosis, dental sensitivity, and dental erosion were evaluated in both groups. The Chi-square test and continuous variables were compared by the Mann–Whitney test and the Kruskal–Wallis test (P value < 0.05, significant). Results: The Mann–Whitney U test on the distribution of the gastric complaints between two groups revealed a significant difference in all the variables. A significant difference was found in the distribution of all the oral manifestations except halitosis and dentinal hypersensitivity between both groups. The Chi-square test between the heartburn and dental erosions revealed a significant association (c2 = 293.761, df = 1, P < 0.001), whereas there was no significant association between heartburn and dentinal hypersensitivity. Conclusion: GERD and dental erosions had no significant correlation, whereas other oral manifestations and mucosal changes were found significant with GERD.

Background: Mucositis, xerostomia, dysgeusia, trismus, radiation caries, osteomyelitis, and osteoradionecrosis are a few examples of radiotherapy (RT) complications, eventually distressing the patient's life. Objectives: To study the oral complications emerging due to RT and evaluate dental management of such complications before, during, and post-RT in oral cancer patients. Methods: Patients were evaluated on various parameters, which include the Oral Hygiene Index Simplified (OHI-S), Periodontal Index (PI), Gingival Index (GI), D – Decayed, M – Missing due to caries, F – Filled, T – permanent teeth (DMFT) Index, mucositis, xerostomia, dysgeusia, and interincisal distance before, during (10th session and last session), and 1 month after the last session of RT were evaluated and compared. Statistical Analysis: The following tests were applied: Chi-square test, analysis of variance (ANOVA) test, and standard deviation method. Results: P value <0.001 in OHI-S, PI, GI, DMFT index, mucositis, xerostomia, and dysgeusia, which is statistically significant. There was no difference found statistically in the interincisal distance. Conclusions: Oral healthcare team serves a vital role in preventing and managing short- and long-term complications of RT. There should be a mandatory prerequisite to visit an oral physician before, during, and after RT for supportive and palliative oral care.

Background: As a multifactorial disorder, temporomandibular joint (TMD) is difficult to diagnose, and multiple factors affect the joint and cause the temporomandibular disorder. Standardization of clinical diagnosis of TMD should be used to reach a definite clinical diagnosis; the condylar bone may degenerate in accordance with these disorders. Aims: Evaluate the correlation between the clinical diagnosis and degenerative condylar change (flattening, sclerosis, erosion, and osteophyte). Materials and Methods: A prospective study with a study group of 97 TMD patients (total of 194 joints) aged 20 to 50. Patients were sent to cone beam computed tomography (CBCT) to assess the degenerative condylar change. Results: No association was found between the clinical diagnosis of TMD with osteophyte and sclerosis. While there was a significant association was found between flattening and erosion and clinical diagnosis. Conclusions: Disc displacement with reduction was the most frequent TMDs. Erosion and flattening were the most frequent bone change found among the different subgroups of clinical diagnosis. Erosion was frequently seen in degenerative joint disease (DJD) with a significant association. While flattening was mostly found in disc displacement without reduction without limited mouth opening (DDwoR without limited) with a significant association.

Background: There is inconsistent data on the effect of fixed orthodontic treatment on the pharyngeal airway dimensions. Aim: The present study aimed to evaluate the effect of orthodontic treatment on airway. Methods: Fifty patients who completed their fixed orthodontic treatment were selected for the study. Pre- and post-treatment lateral cephalograms were collected. The airway parameters studied were Superior Posterior Airway Space, Middle Airway Space, Inferior Airway Space, and Vertical Airway Length, while the soft tissues analysed were the height of the tongue, length of the tongue, thickness of soft palate, and length of the soft palate. The measurements of these parameters were done on all the cephalograms and were tabulated and statistically analysed. Results: There was a significant decrease in the middle airway space in the non-extraction group, while the remaining parameters did not show any significant variation. In the extraction group, there was no significant variation in any of the parameters analysed. Conclusion: There was a significant reduction in the middle airway space, while no significant variation in the upper, lower airway, and vertical airway length in non-extraction cases after the orthodontic treatment. None of the airway parameters and adjacent soft tissues showed any significant variation post-orthodontic treatment in extraction cases.
