Primary bone is the first
tooth sockets. The secondary bones have lower amounts of osteocytes so primary bone is much more easily penetrated by x-ray

Clinical significance
Primary bone or the primary ossification center is the beginning of the bone building process during the first trimester. Calcificed cartilage is basophilic and new bone being made is more acidophilic. The primary ossification occurs in the diaphysis. In contrast, secondary ossification centers appear later at the epiphyses of the cartilage and develop similarly to the diaphysis.[1]
