Primary malignant melanoma of oral mucosa is a rare and aggressive tumor. It is usually seen in the 5 th and 6 th decades of life. Its mainstay of treatment is surgery. It has a very poor prognosis, which is attributed to its late detection and distant metastasis. Dentists are often the first clinicians to come across these lesions and need to be able to identify them at the earliest for a better prognosis. In this article, we present two cases of extensive primary malignant melanoma of the oral cavity. Clinically, both the cases had a similar appearance of grayish-black pigmented nodular swelling on the buccal aspect and grayish-black discoloration on the palatal aspect. There were no significant radiological changes in both cases, indicating the superficial spread of the lesion. A positron emission tomography scan was performed in the second patient, which did not show any distant metastasis. Surgery was advised as a treatment for both the patients.

Dental trauma are accidental injuries, that may occur in any stage of life, be it infancy, childhood, adolescence or adulthood. Most TDIs occur at home, followed by at school and in the street or other public places. Such injuries may have better prognosis if the general public were informed about basic first-aid measures and seek medical care promptly. As dental healthcare providers, it is our responsibility to identify and either provide the necessary care for children with acute traumatic dental injuries or refer the case for optimal care depending on the complexity of the injury and the clinician’s knowledge, and expertise. Dental traumatology requires more attention and profound discussion in paediatric dentistry as dental and oro-facial trauma is being encountered commonly, in children.
