ABSTRACT
The reactive lesions are relatively common in the oral cavity because of the frequency with which the tissues are injured. They often result from a known stimulus or injury such as dental plaque, calculus, or foreign material. Aims: The aim of this study was to review the clinicopathologic features of reactive hyperplastic lesions (RHLs) of the oral cavity at MIDSR, Dental College and Hospital, Latur, Maharashtra, and to compare these data with those of previously reported studies. Settings and Design: The patient case files from the Department of Oral and Maxillofacial Pathology from June 2010 to May 2016 were reviewed for cases of RHLs of the oral cavity. Subjects and Methods: Both clinical and histopathological diagnosis of reactive lesions was selected for the study. Data including the type of the lesion, age, gender, and the site involved were collected. Statistical Analysis Used: Descriptive statistics was applied to the data and differences in frequencies among groups were evaluated using SPSS (IBM Corporation) software. Results: A total of 155 histologically diagnosed cases of RHLs were obtained with a prevalence of 11.7%. The data consist of 56 (36.1%) males and 99 (63.9%) females. The most common lesion clinically was traumatic fibroma (36.5%) and histologically fibrous hyperplasia (37.4%). The reactive lesions clinically presented as either sessile (51%) or pedunculated (49%) lesions. Conclusions: The clinical features of reactive hyperplasia among our patients were similar to those reported previously with divergence in some analyzed data. The novelty in our study was the correlation between histopathology and clinical features which were not reported in literature till date.
ABSTRACT
Objective: To investigate whether the application of thyroid collars (TCs) affects the results of cephalometric study. Study Design: The Steiner cephalometric analysis of the patients was performed using lateral cephalometric radiographs, which were taken twice for each patient: Once using TCs (TC group; n0 = 50) and once without using TCs (NTC group; n = 50). A randomized and observer-blinded diagnostic study with head films taken from the two aforementioned groups was performed and results were evaluated with the t-test and Z-test, using GraphPad® Prism 4 software. Results : Statistical analysis using t-test was performed. The values of the line angles used in Steiner cephalometric analysis were compared for which values of each angle remained unchanged when done using TCs and without TC to the same samples. Conclusions : Lead shielding of the thyroid gland does not affect landmark identification or the specific measurements of the angulations traced during cephalometric analysis. TCs should be routinely applied during cephalometric radiography if cephalometric analyses are limited to the structures above the second cervical vertebra.
ABSTRACT
Molluscum contagiosum (MC) is a cutaneous lesion caused by a DNA virus from the poxvirus family. Worldwide in distribution, MC is most frequently encountered as an easily treated disease of childhood and has rarely been a cause of serious morbidity. With the advent of new populations of immunocompromised individuals, especially those infected with the human immunodeficiency virus (HIV), MC has emerged as a difficult clinical challenge and the focus of renewed interest for dental professionals. This article presents four cases of HIV positive patients afflicted by MC along with a review of the literature on this dermatopathological lesion.
