Biometric is a real time identification system using physical characteristics. The tongue can be used as a novel identification system and a potential forensic tool. Tongue prints can be captured either by clicking a photograph of the dorsum of the tongue or by obtaining an alginate impression. Tongue printing dates back to the era of traditional Chinese medicine. Tongue prints and their interpretation is also important in diagnosing cases of HIV, upper gastrointestinal problems, etc. Multiple studies have been performed to establish a universal classification of tongue prints. Still, there is a lack of availability of data about the population of different geographical locations. Hence, it also opens up new research avenues for upcoming researchers. Keywords: Tongue prints, biometric, identification, forensic odontology, tool. Key Messages: Tongue prints can be used as a reliable new technique for biometrics assessment because of their genetic independence, stability over time, and physical protection from the external environment. Hence, it also opens up new research avenues for upcoming researchers.

Background: Early childhood caries is a virulent form of dental caries that can destroy the primary dentition of infants and preschool children. ECC is a preventable disease and prevention should begin in pre and perinatal. Mothers with poor oral health may be at greater risk of infecting their children. Biologically, the mother is a primary source of Streptococci and young children are dependent on their mother for oral hygiene. Aim: The aims of this study were to assess women's knowledge and experiences of dental health in pregnancy and to examine the selfcare practices of pregnant women concerning their oral health. Methodology: A survey was presented which was designed to assess the knowledge, attitude, and practices of pregnant women regarding infants' oral health. A survey was conducted in and around Vellore at a government and private maternity hospital among pregnant women and new mothers. A self-administered questionnaire consisting of a total of 41 questions concerning basic information on proper infant oral hygiene procedures was given. The statistical analysis was performed. Results: A greater percentage of women were unaware of the importance of their oral hygiene, infant feeding practices and oral hygiene procedure. Conclusion: The present study reflects a need for maternal counselling on infant oral health. Keywords: Infant feeding, Knowledge, Mothers, Oral health.

Traditionally, skin cancers have been divided into two major groups: melanoma, and non-melanoma skin cancer (NMSC). Squamous cell carcinoma (SCC) is the second most common skin cancer in individuals of White European ethnicity and is preceded in frequency by basal cell carcinoma (BCC). Squamous cell carcinoma is estimated to have a lifetime incidence of 7–11% in the USA; whereas that of BCC is 28–33%. 1 Other NMSCs include cutaneous lymphoma, Kaposi’s sarcoma, Merkel cell carcinoma, and other sarcomas. Together, these account for<1% of NMSCs. Factorsthat increase the risk for SCC include Fitzpatrick skintypes I and II (usually White individuals), outdoor occupations (farming, construction work), and exposure to human papillomavirus (HPV) types 16, 18, and 31.2 Exposure to ultraviolet (UV) radiation and sunlight is the greatest risk factor. Here we present a case of SCC in a post burn scar patient with underlying Covid-19. Keywords: Cutaneous Squamous Cell Carcinoma, Covid-19 Pandemic.
