Mentorship availability and needs for junior faculty members at the United States and Australian dental schools.

OBJECTIVES: The aims of this study were to understand the experiences junior faculty have during their professional socialisation as educators and how they perceive the need and value of mentorship. METHODS: A cross-sectional qualitative study design was used. Data were collected in 2019 through a pre-survey and focus groups with junior faculty (defined as 0-5 years) across four institutions in Australia and the United States of America. Framework analysis was used to identify themes in the data, based on our defined research questions, and socio-cognitive career theory was applied to guide our analysis. RESULTS: A total of 22 junior faculty participated in the study. Only one of the four institutions had a formal mentoring programme for junior dental faculty. At this institution, 83% of participants indicated they were likely/extremely likely to remain in dental education. Across the three institutions where formal mentoring for junior dental faculty was not available, only 40% of participants indicated they were likely/extremely likely to remain in dental education. We identified five themes in the qualitative data: motivation for career choice, the importance of relationships, personal goals and the need for self-direction, expectations of the role, and institutional effects. CONCLUSION: Our findings suggest that mentoring is a critical factor in a junior faculty member's experience entering and socialising into a career in dental education. The perceived value of mentoring emerged across all themes, both from the perspective of participants who had received formal mentoring and those who had not.

Intraoral lesion · history of cirrhosis and smoking · Dx?

A 56-year-old white man presented at our dental clinic for routine care. The intraoral examination revealed an asymptomatic red lesion with white vesicle-like areas on the right side of the soft palate. The extraoral examination was normal, and regional lymph nodes were nonpalpable. The patient's medical history included liver cirrhosis and pancreatitis. He also had a 30-year history of alcohol misuse (1-5 drinks per day) and a 30-pack-year smoking history. (The patient had stopped drinking at the time of presentation, and had quit smoking 2 years earlier.) We instructed him to gargle with warm salt water at home and return in 2 weeks. At follow-up, the lesion was unresolved, so a biopsy was performed.

A peripheral giant cell granuloma with extensive osseous metaplasia or a hybrid peripheral giant cell granuloma-peripheral ossifying fibroma: a case report.

INTRODUCTION: Peripheral giant cell granuloma and peripheral ossifying fibroma are clinicopathologically distinct gingival lesions. Both are included in clinical differential diagnoses of common benign and reactive gingival epulides in humans. It is often impossible to make a clinical distinction between the two entities, thereby making definitive diagnosis dependent on histopathologic features. While our search of the English literature revealed several reports of peripheral giant cell granuloma with 'bone formation', we were unable to identify any reports of hybrid peripheral ossifying fibroma-peripheral giant cell granulomas. CASE PRESENTATION: We report a case of a 44-year-old Caucasian man presenting with a three-month history of swelling of his right posterior mandible, related to an area of previous dental implant restoration. A clinical examination revealed modest extraoral facial swelling of his right posterior mandible, while an intraoral examination showed a 45 × 25 × 15 mm sessile, lobular soft tissue mass of the right posterior mandibular gingiva. The mucosal covering of the lesion exhibited focal surface ulceration. A panoramic radiograph showed two implants at the vicinity of the lesion with no other significant findings. An excisional biopsy of the lesion followed by histopathologic examination of the biopsy specimen revealed salient and distinctive features of peripheral giant cell granuloma and of peripheral ossifying fibroma, estimated at near equal proportions. This raises the possibility of a hybrid odontogenic lesion. CONCLUSION: The presentation of this lesion, with areas of peripheral giant cell granuloma along with a distinct area of extensive osseous formation and stroma reminiscent of a peripheral ossifying fibroma, justifies consideration of this as a possible hybrid lesion. Although the biologic behavior of a combined lesion is not anticipated to deviate significantly from that of either of the single entities, this case resurrects an enduring debate as to whether peripheral giant cell granuloma and peripheral ossifying fibroma are simply parts of a disease spectrum, or whether some of these lesions represent true hybrid lesions. It is therefore recommended that more cases with histopathologic features similar to the lesion in our case be reported in the literature to further elucidate the histogenesis of these lesions.

Why use oral splints for temporomandibular disorders (TMDs)?

Several etiologic routes have either been determined or proposed for Temporomandibular Disorders (TMD). Notable among these are myofascial, disc displacement, and arthritides disorders. The absence of concrete and universally accepted evidence-based treatment approaches means that debates as to the precise etiology and treatment of TMDs continue while practitioners attempt to treat and improve the lives of patients who present with these debilitating disorders. The use of oral splints (OS) by clinicians with responsibility to manage TMDs is quite popular, even though its mechanism of action and efficacy remains unclear. This article reviews the rationale for the continued use of OS for the management of TMDs.

NOMA: A Preventable "Scourge" of African Children.

Noma is a serious orofacial gangrene originating intraorally in the gingival-oral mucosa complex before spreading extraorally to produce a visibly destructive ulcer. Although cases of noma are now rarely reported in the developed countries, it is still prevalent among children in third world countries, notably in sub-Sahara Africa, where poverty, ignorance, malnutrition, and preventable childhood infections are still common. This review summarizes historical, epidemiological, management, and research updates on noma with suggestions for its prevention and ultimate global eradication. The global annual incidence remains high at about 140,000 cases, with a mortality rate exceeding 90% for untreated diseases. Where the patients survive, noma defects result in unsightly facial disfigurement, intense scarring, trismus, oral incompetence, and social alienation. Although the etiology has long been held to be infectious, a definitive causal role between microorganisms cited, and noma has been difficult to establish. The management of noma with active disease requires antibiotics followed by reconstructive surgery. Current research efforts are focused towards a comprehensive understanding of the epidemiology, and further elucidation of the microbiology and pathogenesis of noma.Although a formidable public health challenge, noma can be prevented with a potential for subsequent global eradication. To achieve both desirable goals, detection of early disease is crucial because these early lesions respond to conventional antibiotic treatments when instituted side by side with nutritional rehabilitation, and obviates the necessity for extensive surgical reconstruction often indicated in late stage disease. The eradication of noma in the developed world in the mid 20(th) century bears out the notion of a similar outcome following effective preventive strategies in Africa. A fundamental and necessary step towards attaining this goal is for the international community to adopt a perception of noma as an urgent global public health challenge. Research effort toward deciphering the microbiology, molecular events, and pathogenesis of noma also should intensify.
