Since the face carries the identity of an individual, it is the most psychologically significant area of the body. Therefore, any disfigurement to the face such as that caused by burns has potential psychosocial consequences to the victim. The present study aimed at determining the etiology, pattern of occurrence and management of facial burns among patients attended at Muhimbili National Hospital, Dar es Salaam Tanzania. Material and Methods: This was a one-year prospective study of all consecutive patients with facial burns who attended treatment at the Muhimbili National Hospital (MNH). The variables examined included socio-demographic characteristics, etiology, clinical features and management of facial burns. The data were analyzed using SPSS software for windows version 23 (IBM Corporation Chicago, IL, USA). Fisher’s t-test was used and associations were considered significant when p < 0.05. Results: A total of 112 patients with body burn injuries were attended during the period of this study where by 29.5% of the patients had burn injuries to the facial region. The male to female ratio was 2:1 and patient’s age ranged from 17 to 70 years, with a mean age of 30.6 (SD 12.3) years. The etiological factors included open fire that affected (78.8%) of the patients followed by scalding (12.1%) and electricity (9.1%). Majority (81.8%) of the burn injuries were accidental in nature. The most frequently burnt facial aesthetic zones were the zygomatic region followed by the orbits. More than 80% of the participants had complications where by hypo-pigmentation was the commonest (51%) complication of burn injuries encountered. Conclusion: Facial burns affected males twice more than females. Open fire was the most common etiological factor and the zygoma was the most frequently affected facial esthetic zone. Majority of the patients had complications due to burn injury, of which the facial skin hypo-pigmentation was the commonest followed by death.","PeriodicalId":385193,"journal":{"name":"Archives of Oral and Maxillofacial Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131220541","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}

The authors of this study recently observed that the dental implant success rates decrease in patients with COVID-19 disease after dental implant surgery. In a group of 14 patients, 85 dental implants were placed, and 4 of the implants were failed. It was observed that all the patients with failed implants had a positive COVID-19 test 4-6 weeks after the surgery. Six of the 14 patients were affected by COVID-19 and 4 out of 42 implants applied to these patients were failed. All implants were placed by the same surgeon using the same brand of an implant with appropriate primary stability. Only one of these patients had pain during the recovery period, but all other 5 patients with implant failure have no symptoms. Radiological examination reveals neck resorption in only one of the 4 failed implants. This situation brought to the mind of the authors that COVID-19 disease could have negative effects on osteointegration and the success rate of dental implant surgery. After a review of the recent literature, clinically similar results were explained, stating COVID-19 disease may negatively affect bone osseointegration [2].","PeriodicalId":385193,"journal":{"name":"Archives of Oral and Maxillofacial Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122633785","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}

{"title":"Recreating the Face - A Mini-Review of Current Studies on 3D Bioprinting in Oral and Maxillofacial Surgery","authors":"Sen Rwik","doi":"10.36959/379/360","DOIUrl":"https://doi.org/10.36959/379/360","url":null,"abstract":"According to the United States National Institute of Dental and Craniofacial Research, craniofacial anomalies are the most common birth defects. Genetic, epigenetic, and environmental causes lead to craniofacial anomalies which can range from cleft lip and palate to major defects in the development of the skull, face, brain, eyes, ears, and nose. Oral and maxillofacial surgeries are performed on individuals with craniofacial defects, but success of surgery is dependent on nature of the defect. Some defects are too complex which need multiple surgeries, but still not be completely cured by traditional methods. In this direction, 3 dimensional or 3D bioprinting has emerged as a promising modern technology that can significantly benefit the field. A personalized medicine approach to address craniofacial defects is provided by 3D-printing technologies which integrate doctors, engineers and researchers to work for a common goal [1]. Hence, this mini review of literature on 3D bioprinting discusses the technology in the context of craniofacial, and hence oral and maxillofacial therapeutics. In the field of oral and maxillofacial therapeutics, researchers and surgeons are aiming to develop a 3D scaffold by direct 3D printing technology to fabricate complicated tissue grafts. They need to possess all the necessary biological properties and environment for cell division and tissue regeneration. Hence, the current and future challenges of 3D bioprinting will be to achieve the above criteria is a cost-effective and timely manner. Check for updates significantly convenient, greatly improves their outcome, and enhances the quality of life of patients [5]. The Process of 3D Bioprinting The process of 3D bioprinting can be categorized into pre-bioprinting, bioprinting, and post-bioprinting [6-8]. At the very beginning, suitable cells for synthesizing the bioink are isolated and cultured to obtain a large amount of viable starting material. In the pre-bioprinting step, imaging is performed on the tissue that will be bioprinted. The imaging is done by technology like Computed tomography (CT) or cone beam CT in Digital Imaging and Communications in Medicine (DICOM) format and magnetic resonance [6,8,9]. Standard Triangle Language (STL) format is used to provide the image as input to the bioprinter [6,8,9]. Hence, a Computer Aided Design (CAD) model of the target tissue is obtained [6]. Introduction 3D bioprinting has addressed the problems associated with traditional surgeries and therapy. The emergence of 3D printing technology occurred in the 1990’s when synthetic inks were used to generate fabricating scaffolds, leading up to the invention of bioprinting in the 21st century [2]. Bioprinting employs bioinks which are composed of biocompatible substances made of cells or matrices derived from natural sources which have applications in tissue engineering [3,4]. The technology evolved from additive manufacturing where biomaterials are used to develop scaffolds whic","PeriodicalId":385193,"journal":{"name":"Archives of Oral and Maxillofacial Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130902590","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}

This case report describes a patient with mood disorders and fibromyalgia for which he was taking five medications that are associated with xerostomia and hyposalivation. In order to alleviate his oral dryness, he began to use a homemade beverage that discolored his tongue and masked a median rhomboid glossitis.

Curtis, Abomr Diplomat, Catherine, Abomp Diplomat","doi":"10.36959/379/349","DOIUrl":"https://doi.org/10.36959/379/349","url":null,"abstract":"Hybrid odontogenic lesions are a well-recognized phenomenon. They most often show features of various odontogenic neoplasms arising within cyst-like structures. The etiopathogenesis of hybrid odontogenic lesions is not well defined, however, the presence of numerous, closely approximated sources of pluripotent epithelial cells in the developing jaws is likely associated with their development. This case highlights an interesting mixed radiolucent and radiopaque, expansile cystic lesion with a follicular relationship to an unerupted tooth in a young child. Histologically, the lesion showed a combination of dentigerous cyst, calcifying odontogenic cyst and adenomatoid odontogenic tumor. Close radiographic proximity of the hybrid odontogenic lesion to a focal expansion of the gubernacular canal suggests that the adenomatoid odontogenic tumor portion of the hybrid lesion may have arisen directly from this structure, resulting in delayed eruption of the adjacent tooth and subsequent development of a dentigerous cyst with foci of calcifying odontogenic cyst. Complete enucleation of the cystic structure with retention of the associated tooth was performed, with a 6-month follow-up showing complete healing of the surgical site and no evidence of recurrence of the cystic lesion. To date, there have been only six reported cases of lesions with features of both calcifying odontogenic cyst and adenomatoid odontogenic tumor. The current case represents the first documented case of a dentigerous cyst with foci of both calcifying odontogenic cyst and adenomatoid odontogenic tumor. Given the variable nature and biological behavior of the odontogenic entities that compose hybrid odontogenic lesions, unusual clinical presentations and unexpected progression are possible. Further documentation of such hybrid lesions is necessary to fully elucidate how these entities behave clinically, radiographically and pathologically.","PeriodicalId":385193,"journal":{"name":"Archives of Oral and Maxillofacial Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128506734","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}
