Tooth movement by orthodontic force is based upon alveolar bone resorption at compression site and bone formation at tension site of tooth. The function of cyclic AMP is to participate not only in initial action of bone cells by mechanical forces but also in the continuous cellular response leading, to bone remodeling. This experiment was performed to clarify the role of cyclic AMP in bone remodeling by mechanical forces. The orthodontic forces of about 80 gm and 100 gm were applied to the right canines of maxillary and mandibular bone, respectively, in cats, treated for periods of time ranging from one hour to 28 days. Alveolar bones were obtained from compression and tension sites . surrounding tipping maxillary and mandibular canines as well as from contralateral control sites. The samples were extracted, boiled and homogenized, and the supernatants were assayed for cyclic AMP by a radioimmunoassay mothod. The results were as follows: 1. The orthodontic movement of canines was increased to the end of experimental period and the action of orthodontic forces on tooth movement was more effective in maxillary canine. 2. The cyclic AMP levels of alveolar bones in compression and tension sites initially decreased, then increased and remained elevated to the end of experiment. The differences of the cyclic AMP levels between treated sites and non-treated sites were gradually increased. 3. The cyclic AMP levels in treated sites of mandibular alveolar bone was higher than that of maxillary alveolar bone.

Idiopathic midline destructive disease(IMDD) is a subgroup of midline granuloma syndrome, which is a clinical entity characterized by a relentless uilcer ation of the upper air way involving the nose, the palate, and the face, with a fatal outcorne. A 32 year-old male had symptoms of nasal obstruct.ion and rhinorrhea for about 4 months prior to visiting the hospital ad was referred to our Department for evaluation of a verely destruct.ive skin lesions on his face. The patient, revealed unique clinopatholcgic featurs compat with IMDD. These were : 1) prescence of locally destructive lesion which were restricted to the upper respiratory tract. 2) abscence of systemic disease durin the follow up peroid, 3) The histologic features consisted of acute and chronic inflarnmation with a variable dearel of necrosis on the examination of repeated biopsy specimens, 4) inabiliy to demonst rate an infectious causative organisms on repeated laboratory tests.
