The alveolar process is also called the alveolar bone or alveolar ridge. [3] In phonetics , the term refers more specifically to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms. This X-ray film displays a horizontal defect . This X-ray film displays two lone-standing mandibular teeth, #21 and #22: the lower left first premolar and canine, exhibiting severe bone loss of 30-50%.
The loose connective tissue plugs occupying the alveolar spaces often connect to other connective tissue plugs in nearby alveoli via the pores of Kohn creating a characteristic butterfly pattern on histology. [9] There is usually minimal to no interstitial inflammatory changes in biopsies of organizing pneumonia. [9]
Sharpey's fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong predominantly type I collagen fibres connecting periosteum to bone. They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue.

The alveolar type II epithelial cells are more resistant to damage, so after an insult to the alveoli, most of the damage will occur to the alveolar type I epithelial cells. [5] Left side demonstrate the structure of a normal alveolus including the difference between type I and type II alveolar epithelial cells.
The dog's footpad is a fatty tissue locomotive-supporting organ, present at the bottom of the four legs, consisting of digital pads, a metacarpal pad, and a carpal pad, with dewclaw near the footpad. [26] When a dog's footpad is exposed to the cold, heat loss is prevented by an adaptation of the blood system that recirculates heat back into the ...
As growth of the alveolar bone continues and the adjacent permanent teeth erupt, the ankylosed deciduous tooth appears to submerge into the bone, although in reality it has not changed position. Treatment is by extraction of the involved tooth, to prevent malocclusion , periodontal disturbance or dental caries .
