Teeth measurements were used in forensic medicine for sex determination and can support dental students and orthodontists to apply their practical sections. Aims: The current study aimed to measure the crown dimensions from the buccolingual (BL) and mesiodistal (MD) directions and their benefits for adult Sudanese maxillary molars teeth. Material and methods: This study was conducted on 120 adult Sudanese extracted sound maxillary molar teeth (60 male and 60 female), ages ranging between 26 to 48 years.
