With these concepts in mind, let us review the histology of the periodontal pocket, especially in the area of tissue destruction and healing after the periodontal therapy instituted. The periodontal pocket is described as one which occurred with destruction of the supporting periodontal tissues. Progressive pocket deepening leads to destruction of the supporting periodontal tissues and loosening and exfoliation of the teeth. The suprabony pockets are those which the bottom of the pocket is coronal to the underlying alveolar bone. The infrabony pockets are those which the bottom of the pocket is apical to the level of the adjacent alveolar bone and the lateral pocket wall lies between the tooth surface and the alveolar bone.

Other systemic conditions associated with impairment of growth, such as anemia (hypoxic hypoxia, histotoxic hypoxia, and anemic hypoxia) and renal failure, have also been correlated with DTE and other abnormalities in dentofacial development. Continue reading

- Ectopic canine @ stringertorthodontics
Permanent teeth may submerge inside the jaw bone or gums for a few reasons.
- Impaction due to insufficient space
- Missing genetically
- Ectopic tooth – tooth is not at its original eruption site, it has been displaced to somewhere else. This usually happens to permanent canine.
- Ankylosis of baby teeth ( baby teeth’s roots fused to jaw bone causing it to retain and not falling off accordingly)
