Study notes
A 21-year-old patient named Sam comes in with a broken front tooth (Maxillary Central Incisor) after falling from a cycle. The 'Incisal Edge' is missing. The dentist identifies this as a 'Class IV fracture.' To fix it, the dentist uses a tooth-colored material called 'Composite.' The dentist carefully sculpts the 'Mamelons' (the three little bumps found on new incisors) and ensures the 'Lingual' side is smooth so Sam's tongue feels comfortable. After the treatment, Sam can bite into an apple again because the sharp cutting edge is restored. The dentist checks the 'Occlusion' (the way Sam bites) using a special blue paper to make sure the repair isn't too thick.
