Objectives: Over the past several decades, oral cancer has been the most common malignancy among Sri Lankan males and the top 10 cancer among females, disproportionately affecting low socio‐economic groups. Sri Lanka is a lower‐middle‐income developing country (LMIC), currently striking through an economic crisis, and social and political unrest. Occurring at an accessible body site and predominantly attributed to potentially modifiable health‐related behaviours, oral cancer should be preventable and controllable. Unfortunately, broader contextual factors that are socio‐cultural, environmental, economic, and political and mediated through social determinants of people's lives consistently hinder progress. Many LMICs with a high burden of oral cancer are now gripped by economic crises, consequent social and political unrest, all compounded by reduced public health investments. The aim of this review is to provide a critical commentary on key aspects of oral cancer epidemiology including inequalities, using Sri Lanka as a case study. Methods: The review synthesizes evidence from multiple data sources, such as published studies, web‐based national cancer incidence data, national surveys on smokeless tobacco (ST) and areca nut use, smoking and alcohol consumption, poverty headcount ratios, economic growth, and Gross Domestic Product (GDP) health expenditure. National trends in the oral cancer, ST use, smoking and alcohol consumption in Sri Lanka are identified alongside inequalities. Results: Using these evidence sources, we discuss 'where are we now?', together with the availability, accessibility and affordability of oral cancer treatment services, oral cancer prevention and control programmes, tobacco and alcohol control policies, and finally, outline macroeconomic perspectives of Sri Lanka. Conclusions: Finally, we speculate, 'where to next?' Our overarching goal of this review is to initiate a critical discourse on bridging the gaps and crossing the divides to tackle oral cancer inequalities in LMIC such as Sri Lanka.

The brief commentary describes the development of, and training in delivering outreach psychosocial oncology care for oral cancer patients by PHNOs in Sri Lanka. [Extracted from the article]

Background: The term "primary intraosseous squamous cell carcinoma" was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic odontogenic tumor is considered extremely rare.Case Presentation: In this case report we report a case of a 50-year-old Sri Lankan woman who complained of pain and increase in the size of a swelling at the anterior mandible, which had been present for over 1 year. The increase was significant for 1 month with accompanying numbness of the left half of her lip. Cone beam computed tomography results revealed an irregular radiolucent lesion involving most of her mandible and, except in the anterior part, very little buccolingual expansion was seen that suggested a keratocystic odontogenic tumor. An excision biopsy of the cyst lining confirmed a squamous cell carcinoma arising from a preexisting keratocystic odontogenic tumor.Conclusions: Even though primary intraosseous squamous cell carcinoma arising from a keratocystic odontogenic tumor is considered to be very rare, the present case is comparable to most of the aspects cited in the literature. The current case emphasizes the importance of careful investigation of swellings present in the mandible. Clinicians as well as patients should be aware and detect these changes to avoid being clinically negligent. [ABSTRACT FROM AUTHOR]

Background: The habit of inserting foreign objects into body cavities is seen in children and in adults with intellectual disability. Usually, the foreign objects cause chronic inflammation and local tissue destruction, which give rise to symptoms. Diagnosis at an asymptomatic stage is uncommon when the history is not suggestive. We describe a rare case where a foreign object was misdiagnosed as an odontoma in a patient with an alveolar cleft.Case Presentation: A radiopaque round mass was noted on the radiograph of a 12-year-old Sinhalese boy who was awaiting an alveolar bone graft. Apart from problems related to the alveolar cleft and mild halitosis, he was otherwise healthy. This was suspected to be an odontoma in the cleft region. During alveolar bone graft surgery, a button battery was recovered that was later confirmed as having been self-inserted by the child. Alveolar bone graft surgery was delayed because of local chronic inflammation due to the foreign object. Three months later, complete healing of the site was noted when reexplored for alveolar bone grafting.Conclusions: It is important to include foreign objects in the radiological differential diagnosis in asymptomatic children. Furthermore, cone beam computed tomography should be considered in suspected cases. Early removal with thorough debridement causes minimal tissue destruction. [ABSTRACT FROM AUTHOR]

This study assesses radiation doses in cone beam computed tomography (CBCT) procedures in Sri Lanka, with the goal of establishing initial diagnostic reference levels (DRLs). Data from 1162 retrospective scans across four institutions were analyzed, and the medians of the pooled dose distribution for seven clinical indication categories were presented as the DRL values. The proposed DRLs based on clinical indications are 1013 mGy·cm2 for pathological conditions including cysts, tumors, and lesions, 1307 mGy·cm2 for implant planning, 1266 mGy·cm2 for presurgery assessment, and 1585 mGy·cm2 for evaluation of sinus and nasal pathology, temporomandibular disorder, and facial trauma. Considerable variability in doses across facilities was observed, driven by differences in equipment and imaging practices. Therefore, this study recommends adopting suggested DRL values as benchmarks, standardizing protocols to reduce dose variability, and implementing a national framework for regular updates of DRL values., (© The Author(s) 2024.
