During the second wave of COVID-19 India reported most of the cases of mucormycosis which is termed as COVID-19-associated mucormycosis (CAM). Aim: The purpose of this study is to describe and understand the clinical and radiographic findings related to COVID-19 associated rhinomaxillary mucormycosis. Methods: In this observational study 76 individuals with proven rhinomaxillary mucormycosis were included. The demographic profile, predisposing factors, anatomic structures involved, oral manifestations, radiographic findings management, and 90-day mortality were recorded and analyzed. Results: Among 76 individuals with COVID-19-associated rhinomaxillary mucormycosis diabetes mellitus was present in 93.42% of cases. Almost all patients received corticosteroids during COVID-19 treatment. The maxilla was most commonly involved in around 98.6% of cases. Interestingly 1 case involving the mandible was noted and the maxillary sinus was the most commonly involved. Mortality occurred in 1.31% (n=1) of cases. Conclusion: Diabetes was the most common predisposing factor. Administration of corticosteroids was evident. A considerable number of patients developed diabetes during the treatment of COVID-19. Early signs and oral manifestations of rhinomaxillary mucormycosis play a pivotal role in the early diagnosis and prompt treatment to reduce mortality and morbidity in COVID-19 associatedrhinomaxillary mucormycosis patients.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"99 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74380459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Four 3D digital casts of an atrophic mandible, with a single implant-retained crown with a 3:1 crown-to-implant ratio, were created for finite element analysis. The implant diameter used was either 4 mm (regular) or 6 mm (wide), both with 5 mm length. A 200 N axial or 30º oblique load was applied to the mandibular right first molar occlusal surface. The equivalent von Mises stress was recorded for the abutment and implant, minimum principal stress, and maximum shear stress for cortical and cancellous bone. Results: Oblique load increased the stress in all components when compared to axial load. Wide diameter implants showed a decrease of von Mises stress around 40% in both load directions at the implant, and an increase of at least 3.6% at the abutment. Wide diameter implants exhibited better results for cancellous bone in both angulations. However, in the cortical bone, the minimum principal stress was at least 66% greater for wide than regular diameter implants, and the maximum shear stress was more than 100% greater. Conclusion: Extra-short dental implants with wide diameter result in better biomechanical behavior for the implant, but the implications of a potential risk of overloading the cortical bone and bone loss over time, mainly under oblique load, should be investigated.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89400223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Regular conventional (Tetric N-Ceram – TNC, and Polofil Supra – PFS), regular bulk-fill (Tetric N-Ceram Bulk fill – TBF, and Admira Fusion X-tra – AFX), and low viscosity bulk-fill resin composites (Tetric N-flow – TNF, and X-tra Base – XTB) were used to restore 180 dentin conical preparations.

Clinical intraoral inspection was performed by a single practitioner, with mucositis classification performed according to the WHO oral toxicity scale.

Methods: A cross-sectional questionnaire-based study was conducted with a convenience sample of dentists in Belo Horizonte, in a period of 8 weeks. The questionnaire was self-applied and was structured with 10 items about the dentists’ demographic characteristics, professional profile, and knowledge about bisphosphonates. Associations in the data were analyzed by with the Fischer’s exact test with a significance level of 5%. Results: Of the 214 participating dentists, 163 (76.17%) were women, and 51 (23.83%) were men, with age ranged for 21 to 73 years (mean of 30 years) and mean of 6 years of professional activity. Nearly half (106/49.53%) reported having knowledge about bisphosphonates, and undergraduate courses were the primary source of such information (73/34.11%).

Last, only nine dentists (4.20%) could identify all examples of the drugs, and their capacity was associated with self-reported knowledge (p<0.05).
