The hard tissue forming the main body of a tooth, lying beneath the enamel; an alternative spelling of dentin.
British English variant spelling of 'dentin,' both deriving from Latin 'dens' (tooth) with the suffix '-in.' The 'e' ending is preferred in British and some Commonwealth English conventions.
Dentine and dentin are the same material—the different spellings reflect whether you're reading British or American dental literature, similar to how 'colour' and 'color' diverged in English.
