Hence gingivitis occurs,which in reality becomes interstitial, or interstitial inflammationappears which in reality becomes a gingivitis. No matter what the cause may be, or whether the initial lesionbe in the gum or interstitial structure, absorption of the alveolarprocess results. Three forms of the absorption of the alveolar process are alwayspresent—Halisteresis, Volkmanns perforating canal and lacunaror osteoclast absorption. These are named in the order of the rapid-.
