NEET PG DENTAL EXAM

Detailed explanation-1: -Cementum is reportedly less mineralized (about 45% inorganic material by weight) and softer than other mineralized tissues. This may be because a high proportion of cementum matrix consists of extrinsic Sharpey’s fibers which are only partially mineralized.

Detailed explanation-2: -Dental enamel is greatly mineralized in its composition with approximately 92%–96% of inorganic matter, 1%–2% organic matter, and 3%–4% of water, weight/weight (w/w). Such high percentage of inorganic matter is what makes the dental enamel brittle and nonvital.
