Dentistry where there is no Dentist: A retrospective analysis of urgent dental care reported through the British Antarctic Survey Medical Unit (BASMU), 2015 - 2020.

File replaced (incorrect version) on 04/10/2022 by KT (LDS).AIM: To evaluate the nature of dental related morbidity in British Antarctic Survey (BAS) deployed personnel, and to compare the findings to those in other deployed population groups. Additional aims include outlining the evidence-based approach to further developing a training programme for non-dentists, to manage dental emergencies. METHODS: A retrospective analysis of dental morbidity between 2015 - 2020 reported through the British Antarctic Survey Medical Unit (BASMU) database of dental reported morbidity recorded by deployed medical officers. RESULTS: Analysis and comparison of dental morbidity in deployed personnel to austere environments revealed similarity, in that relatively minor conditions led to the most significant number of presentations for personnel seeking dental advice when deployed. CONCLUSIONS: Dental morbidity for deployed personnel in austere conditions can present with a range of symptoms from relatively minor to severe. Use of best evidence to configure training packages to likely presentations, may limit likelihood of necessitating evacuation from remote locations, or limit morbidity when evacuation is not feasible

Neurological complications following extrusion of sodium hypochlorite solution during root canal treatment.

AIM: To report the presentation and management of two cases with neurological complications secondary to the extrusion of sodium hypochlorite solution into the facial soft tissues during root canal treatment. SUMMARY: The clinical features, with particular emphasis on nerve deficit following inadvertent extrusion of sodium hypochlorite, are discussed and its management highlighted. Early and aggressive treatment is advocated following such incidents in order to reduce potentially serious complications. KEY LEARNING POINTS: *Neurological sequelae can follow inadvertent hypochlorite extrusion. *Early recognition may avert a potentially more serious outcome. *Active hospital treatment including intravenous steroids and antibiotics is recommended

Atypical features in pleomorphic adenoma--a clinicopathologic study and implications for management.

Pleomorphic adenoma is the most common salivary gland neoplasm and infrequently undergoes malignant transformation. Carcinoma ex pleomorphic adenoma is typically an infiltrative neoplasm with features of cellular pleomorphism, high mitotic activity, peri-neural and vascular invasion. More recently, sub-groups of pleomorphic adenoma have been described exhibiting vascular invasion and features of malignancy without evidence of extra-capsular extension. There is little information in the literature regarding how these different histological variants influence clinical presentation and outcome following primary treatment. Following a review of 100 consecutive pleomorphic adenomas removed from the major salivary glands, 4 cases with atypical histological features were found. Three tumours exhibited features of dysplasia/carcinoma without evidence of extra-capsular invasion and a further case demonstrated benign vascular invasion. There were no clinical features suggestive of the atypical nature of these neoplasms, though fine needle aspiration cytology (FNAC) was suspicious of a malignancy in 2 cases and CT scan in 1 case. Patients underwent a superficial parotidectomy or submandibular gland excision based on the location of the lesion. All lesions were completely excised and there were no recurrences in this series
