RESUMEN

Direct pulp capping (DPC) is a vital pulp therapy, wherein accidental or carious pulp exposures can be capped with various materials to induce reparative dentine formation. One of the major factors that determine the success of direct pulp capping procedures is the material used. Therefore, it is of interest to evaluate and compare the efficacy of a new material, Tristrontium aluminate in comparison with the widely used materials such as ProRoot MTA, Biodentine & TheraCal LC. Hence, 40 premolars scheduled for extraction for orthodontic treatment, were equally divided into 4 groups and iatrogenic DPC was done using one of the study materials. The premolars were then extracted after 90 days & assessed for the formation of Dentine Bridge and pulpal response elicited by the materials using CBCT and histopathological analysis. All the materials tested in the study were successful in inducing dentine bridge formation & maintaining pulp vitality. Thus, the novelty of Tristrontium aluminate for potential applications in future is eminent.

RESUMEN

Background: Although oral cancer is multifactorial in origin only few had evaluated the diagnostic parameters for candidal infection in oral squamous cell carcinoma (OSCC). Aims: To compare and assess the accuracy of Calcofluor White (CFW) to that of conventional staining methods to identify the presence of candidal infection in OSCC. Methods: Archival collections 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. Results: The study comprised 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%). Conclusion: 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 was 60.4%. Although CFW staining can come with high false positive they are a useful test for ruling out candida infection when the test result is negative.

RESUMEN

The presence of eosinophilic Toto bodies in oral lesions could be found in a variety of situations and sometime may present a challenge to the pathologist. We present three case reports where the oral biopsy was taken from the gingival region of a 30-year-old female, a 32-year-old male patient and another from the buccal mucosa of a 67-year-old male patient. Histopathologically, the three cases were finally diagnosed as pyogenic granuloma and moderately differentiated squamous cell carcinoma with the presence of clusters of Toto bodies in the upper spinous layer of stratified squamous epithelium.

RESUMEN

Gorlin syndrome is an autosomal dominant inherited condition that exhibits high penetrance and variable expressivity. The syndrome is caused by mutations in PTCH, a tumor suppressor gene that has been mapped to chromosome 9q22.3-q31. It is observed that most aggressive forms of keratocystic odontogenic tumor are the first signs of this syndrome which show a high recurrence rate due to its varied histopathological features. The other components are multiple basal cell carcinomas of the skin, intracranial calcifications and rib and vertebral anomalies. In addition, >100 minor criteria have been described with two major and one minor criteria or one major and three minor criteria necessary for confirmatory diagnosis. It is a rare syndrome having an estimated incidence of 1 in 50,000-150,000 in the general population with a 3:1 male/female gender predilection. Here, we report the case of a 14-year-old female patient diagnosed with Gorlin syndrome.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
