A problem of long standing in the study of dentin and enamel is the exact nature and structure of the inorganic material in these tissues. A review of these studies from the time of Berzelius in 1845 up to 1949 has been published by Armstrong (1). In general the mineral component of teeth as well as bones consists chiefly of a basic calcium phosphate which is most probably hydroxyapatite (2, 3)...

Bone is the most implanted tissue after blood. The major solid components of human bone are collagen (a natural polymer, also found in skin and tendons) and a substituted hydroxyapatite (a natural ceramic, also found in teeth). Although these two components when used separately provide a relatively successful mean of augmenting bone growth, the composite of the two natural materials exceeds thi...

The number, shape and sizes of intermuscular bones have been studied in table size (around 1200g). rohu, catla and mrigal after microwave cooking and dissection. Carp intermuscular bones have varied shape and size. These bones are of two types, Y pin bones and straight pin bones. Total number of pin bones are highest in mrigal (110 nos.) followed by catla (108 nos.) and rohu (104 nos.). Y pin b...
