Eosinophilic granuloma in jaw bone: a pare pediatric case report

Background: Eosinophilic granuloma (EG), one of the three clinical forms of Langerhans cell histiocytosis (LCH), is a benign inflammatory reaction to an unknown etiologic agent. It most commonly occurs in children and young adults. The most frequently involved bones are the skull, the ribs and the femurs. Alongside the cranium, the maxilla and mandible can also be affected.Case Details: Herein, we report a case of eosinophilic granuloma in a ten years old boy involving posterior quadrants upper and lower jaws as a destructive lesion involving gingiva, periodontium and alveolar bone. Involvement of other bones is ruled out by nucleotide imaging study.Conclusion: EG should be considered as a differential diagnosis whenever there is a bony destructive lesion involving alveolar bone of the Jaws. Early diagnosis and surgical intervention will resolve the lesion.Keywords: Eosinophilic granuloma, langerhans cell histiocytosis, oral manifestations, alveolar bone and surgical curettag

Comparative evaluation of the metal post and fiber post in the restoration of the endodontically treated teeth

Background: Post-retained crowns are indicated for endodontically treated teeth (ETT) with severely damaged coronal tissue. There are still controversies for the most suitable choice of restorative material and the placement method that will result in the highest success rate. This clinical study compares the metal post and fiber post ins the restoration of the endodontically treated teeth. Materials and Methods: Forty endodontically treated and indicated for the post and core were selected for the study and divided into 2 groups equally. In, one group patient′s teeth were restored by metal post, while other group patient′s teeth were treated by fiber post. Comparative evaluation was done on follow-up of the patients on the basis of selected clinical and radiographical criteria. The results were compared using student′s t test with the help of IBM SPSS Statistics 20. Results: More number of failures was noted in patients whose teeth restored with the metal post as compared to those of the fiber post, both clinically as well as radiographically. (Student′s t test, P < 0.01). Conclusion: From the present study, it was shown that fiber post retained restored teeth has less chances of failure as compared to that of metal post. But the results of the present study should be supported by carrying out study on large scale

Comprehensive Knowledge and Preparedness among Dental Community to Confront COVID-19&mdash;A Multicentric Cross-Sectional Study

The healthcare policy changes need to be updated for better management of the COVID-19 outbreak; hence, there is an urgent need to understand the knowledge and preparedness of healthcare workers regarding the infection control COVID-19. Therefore, the present study aims to assess the knowledge and preparedness towards COVID-19 among dentists, undergraduate, and postgraduates in dental universities one year after the COVID-19 outbreak. The multi-centric cross-sectional study was conducted by evaluating 395 structured, pre-coded, and validated questionnaires obtained from sample units comprising full-time dental students (undergraduates, interns, and postgraduates) and dentists who were currently in practice and who were able to comprehend the languages English or Arabic. The first part of the questionnaire included questions related to demographic characteristics. The second part of the survey consisted of questions that address knowledge concerning COVID-19. The third part of the survey addressed questions based on the preparedness to fight against COVID-19 including sharp injuries during this period. Comparing the knowledge scores of dentists, dental undergraduates, and postgraduates using the ANOVA test, dentists have higher knowledge and preparedness scores than postgraduates and undergraduates (p-value &lt; 0.05). Univariate logistic regression analysis demonstrated that undergraduates and postgraduates were 2.567 and 1.352 times less aware of the personal protective measures against COVID-19 than dentists, respectively. Dentists had the comparatively better perception in knowledge and awareness of COVID-19 than undergraduates and postgraduates
