Explanation:
Detailed explanation-1: -Each tooth begins to develop from four or more growth centers. These centers grow out from the tooth germ and are known as developmental lobes. The lobes grow and develop within their bony crypt until they fuse. This fusion of the lobes is called coalescence.
Detailed explanation-2: -They developed from four lobes, three labially and one lingually (palatally), the lingual (palatal) lobe being represented by the cingulum. Each labial lobe of the incisor terminates incisally in rounded eminence known as mamelon. Unworn, newly erupted incisors have three small mamelons forming the incisal ridge.
