hello friend here's your answer..
The main distinctions between premolar and molar teeth are in their size and shape. While a molar has four cusps or points, a premolar has only two. Molars are also significantly larger than their bicuspid neighbors. ... Molars, in contrast, all have at least two roots, with the upper molars typically having three...
The difference between Enamel and Dentin is the hardest tissue is enamel in the whole human body. The only ectodermal derivative of tooth is enamel. ... On the other hand the bulk of the tooth is dentin or dentin form the bulk of tooth
Difference Between Enamel and Cementum is that the enamel is the hardest tissue in the human body. It is the only ectodermal derivative of the tooth. Inorganic constituents account for 96% by weight and they are mainly calcium phosphate in the form of hydroxyapatite crystals. While the cementum is comparable to bone in its proportion of inorganic to organic constituents and to similarities in its structure. The cementum is thinnest at its junction with the enamel and thickest at the apex.
The pulp's sensory role is important, but it has other roles as well. The pulp functions to form dentin, among other things. It supplies nutrients and moisture the surrounding areas of the tooth. The pulp also helps protect the tooth, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root
A:Primary teeth are Milk teeth, which appear in the mouth at 6-7 months and shed by 11 years. These are 20 in number. Permanent teeth appear at 6-7 years and the last permanent tooth (Wisdom tooth) appears at the age of 17-23 years. Most permanent teeth erupt at the place of milk teeth except few...
