Background:The global prevalence of type 2 diabetes continues to rise. Interest has been increasing recently in noninvasive diagnostic procedure. Hence, an attempt has been made by the present study to analyze the changes in cytomorphometry in exfoliated buccal and gingival mucosa cells in type 2 diabetic patients.Aim:The aim of this study was to analyze the cytomorphometric changes in exfoliated cells of gingiva and buccal mucosa as an adjunct to diagnosis of diabetes.Materials and Methods:In the present study, fifty known type 2 diabetic patients were taken as study group, and the control group was comprised of fifty healthy individuals. Smear was prepared from buccal mucosa and gingival epithelium of both study and control groups and was stained by rapid Papanicolaou (Pap) stain. Stained smears were subjected to cytomorphometric analysis using Lynx Biolux (Lawrence and Mayo) image analysis software. In each Pap smear, 100 cells were evaluated for nuclear area (NA), cytoplasmic area (CA) and cytoplasm to nuclear ratio (CNR).Results:Mean NA was significantly higher (P < 0.05) in study group whereas mean CA did not exhibit any statistically significant difference (P > 0.05). The mean CNR was significantly lower in the study group (P < 0.05).Conclusion:This study contributes to the general understanding of the alterations in the cellular pattern of buccal and gingival mucosa cells in diabetic patients and can be used as an additional tool to aid in the evaluation of oral mucosal alterations in diabetes mellitus.
Background:Predentin, the unmineralized organic matrix is important in maintaining the integrity of dentin. It is usually thick where active dentinogenesis occurs. A wide variation in its thickness is reported. Hence, we determined the variation in predentin thickness at various sites of different age groups.Materials and Methods:60 freshly extracted teeth (maxillary and mandibular first premolars) were divided into three groups with 20 teeth in each as, Group 1 - teeth with incomplete root formation (age <16 years), Group 2 - teeth with complete root formation (aged between 16 and 30 years), Group 3 - teeth of patients aged above 30 years. The teeth were fixed, decalcified and sections of 6 μ thickness were obtained, and stained with hematoxylin and eosin. The distance between the odontoblastic cell layers of the pulp to the border line of the dentin was considered for the measurement of the predentin thickness. A total of nine sites were considered for each specimen.Results:The present study revealed varied mean predentin thickness at all nine sites in all three age groups. Maximum and minimum thickness was observed at the apex and pulp floor respectively in all three groups. There was a statistical significant difference in predentin thickness between groups 1 and 3 and 2 and 3.Conclusion:The predentin thickness in the first group gradually increased toward the growing end near the apex, while it was relatively constant in the second group and increased overall thickness at all the sites in the third group. A notable finding was a linear increase with age in width of the predentin and the thickness vary as a function of odontoblastic activity during different stages of tooth development.
Haemangiomas are the most common benign soft tissue tumor of the oral cavity. It often presents at birth or soon after, and appears as a soft and vascular swelling in lip, tongue, or buccal mucosa. This article reports a rare case of intra muscular haemangioma of the buccal mucosa in a 27-year-old female patient.
Fibrosarcoma is a malignant tumor of fibroblasts. At one time, it was considered one of the most common soft tissue sarcomas. However, the diagnosis of fibrosarcoma is made much less frequently today because of the recognition and separate classification of other spindle cell lesions that have similar microscopic features. Of all the fibrosarcomas occurring in humans, only 0.05% occur in the head and neck region. Here, we present a case of 22-year-old female patient with the swelling on the left anterior aspect of the face. Histopathologically, the lesion was diagnosed as fibrosarcoma and immunohistochemically, the lesional cells showed positivity for vimentin.
Background Forensic odontology deals with age, sex, and race determination of the deceased at crime scenes, disasters, or natural calamities. Studies regarding the role of secondary dentin in age estimation have been documented on a several occasions in the literature but use of secondary dentin in gender predilection has not yet been documented. So, the present study was aimed at using the secondary dentin as a diagnostic tool in gender predilection. Materials and Methods The study included a total of 20 samples (10 males and 10 females). Extracted teeth were collected and placed in 10% neutral buffered formalin solution. The sections were ground on Arkansas stone until the appropriate thickness of the ground sections was achieved. The freshly prepared ground section was mounted on a slide using DPX mounting media. Ground sections were visualized under a microscope and the thickness of secondary dentine was measured using the image analysis software. Results The data were collected and subjected to group statistics. The secondary dentin thickness of all the samples, males and females, was measured. It was observed in our study that the mean thickness of secondary dentin was more in male samples (0.2970) with the standard deviation of 0.01494, as compared with that of females where the mean thickness was found to be 0.1970 with the standard deviation of 0.02058. Conclusion This study has shown that variation in secondary dentin thickness does exist between male and female groups. This criterion can be considered as an aid for gender determination in the future.
Although oral cancer is multifactorial in origin only few had evaluated the diagnostic parameters for candidal infection in oral squamous cell carcinoma (OSCC). We aims to compare and assess the accuracy of Calcofluor Whilte (CFW) to that of conventional staining methods to identify the presence of candidal infection in OSCC. Archival collection of 43 OSCC were retrieved for this investigation. Standard staining protocol was followed for the index test (CFW) and reference standard (Periodic Acid Schiff). Two examiners were blinded for either one of the staining techniques. Diagnostic test evaluation and Kappa statistic was calculated using MedCalc software. The study comprised of 37 males, six females, and their mean age at the time of presentation was 51 (range 23 to 75 years). The sensitivity and specificity of CFW was 75.8% (CI 57.7 to 88.9%) and 10.0% (CI 0.2 to 44.5%). While the positive predictive and negative predictive values were 63.1% (CI − 50.6% − 74.0%) and 67.0% (CI − 49.2% − 81.0%). Our results show minimal agreement with PAS with a Kappa score of 0.148 (95% CI = 0.39 to 0.09). Overall detection rate was similar for both the index test and reference standard although there was considerable number of intermediate test results. Sensitivity of CFW was comparable to that of earlier studies but specificity was low and the degree of concordance of 60.4%. Although CFW staining can come with high false positive they are an useful test for ruling out candida infection when the test result is negative.
Mucormycosis is considered to be a rare notorious fungal infection mainly affecting diabetics with or withoutketoacidosis & immunocompromised patients, with high mortality rate. Occurrence of Mucormycosis as animplication of Covid-19 has not yet been reported. We present a case of aggressive mucormycosis in a Postcovid-19 type-2 diabetic patient and aim to illustrate the possible Covid-19 effects on body and a dire needfor early diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
