In this work the problems due to shortage of proper or adherent gum have been analyzed, further has been referred the clinical cases corresponding to the periodontal indications, which foresee the reconstruction of an insufficient superficial periodontium. Moreover have been described the surgical techniques of the free graft.
The oral breathing can change the functional connections during the development of the facial bones of the children. All this causes an abnormal growth of the facial bones and of the dental structures. This work developed a new discipline to remove this problem.
After the description of the etiopathogenetic aspects and of the pathologic anatomy lesion more typical of the Paget's disease, the A.A. describe a interesting case of the mandible's degeneration in a patient with chronic osteoporosis. The patient does not masticate. The treatment has been to remodelling of the mandible. We made a scrupulous check of laboratory research and the radiographical, biological and histological reports to exclude osteosarcoma and gigantic cells tumour.
In this study gingival crevicular fluid was used as a parameter to estimate the efficacy of initial treatment in diabetic patients. The patients with diabetes had significantly more gingival inflammation before initial treatment than after. A Periotron with Periopaper was used to measure gingival crevicular fluid.
The basis of Periodontal treatment is represented by scaling and root planing. The aim of this study was to compare root morphology after the use of three currets: a new Hu Friedy Gracey 7/8, a semi-new Hu Friedy Gracey 7/8, a worn Hu Friedy Gracey 7/8. The research indicates that manual treatment with the new curette is effective in removing tartar but can cause excoriations on the enamel of the tooth. In contrast, the use of the semi-new curette is less damaging and obtains the same results removing tartar without injuring the enamel surface.
Retrospective analysis of a multidisciplinary approach between surgery treatment a periodontal treatment. In our experience the surgery treatment of the squamous cell carcinoma has been completed by periodontal treatment to eliminate the secondary consequences such as bleeding and salivating++ from the labial chyme.
An interesting of granular-cell Myoblastoma occurred on the chirny area of a patient bearer of an inferior dental prosthesis gives the starting point for a revision of all Histopathogenetic theory about the true origin of these rare and discussed neoformations mostly sealed on the oral cavity.
The diagnosis of lower intestinal hemorrhage usually follows the successive sequence: a) digital rectal examination, b) rectosigmoidoscopy, c) barium enema, d) colonoscopy. This latter method has proven to be the most sensitive. This study is a retrospective examination of the results obtained by emergency colonoscopy on the diagnosis and treatment of lower intestinal hemorrhage. Out of 1258 colonoscopy procedures performed between January 1983 and June 1988 in the Digestive Endoscopy Unit of our Institute, 44 (3.5%) were emergency procedures (within 48 hrs. after recovery) due to lower intestinal hemorrhage. The most frequent causes of hemorrhage found were the following: 1) hemorrhagic colitis (20.5%), 2) polyps (13.6%), 3) hemorrhoids (13.6%), 4) carcinoma (9.0%). The hemorrhagic source was not established in 9 cases (20.5%). The sensitivity of this method was therefore 97.2%. In 6 cases of hemorrhagic polyps treatment to stop bleeding was also possible by means of the colonoscopy (endoscopic polypectomy). In our experience, the emergency colonoscopy was found to be a highly sensitive diagnostic procedure for lower intestinal hemorrhages, permitting even definitive treatment of the lesion in 13.6% of cases with no complications associated with the technique. We feel therefore that, when available, it should be considered the first and foremost exam to be performed for emergency diagnosis of colo-rectal hemorrhages.
The purpose of the present investigation was to test concept that initial treatment is effectual to maintain gingival health. The principal local aging factor is represented by plaque accumulation and gingival inflammation. The results of this study have proved that initial treatment is effectual only on pockets measuring less than 4 mm to periodontal probing. Instead a surgical periodontal treatment is requested and more indicated on pocket depths measuring about or more than 6 mm to periodontal probing.
The present paper briefly outlines the pathogenesis of cleft palate and proposes a classification system for cleft palate since both are considered essential for the understanding and assessment of its sequelae. The Authors describe one case of cleft palate. Cleft palate patients present functional and aesthetic alterations in the maxillomandibular area that often require prosthetic correction. Given the features of these malformations therapy and rehabilitation should be programmed as soon as possible after birth and the plastic surgeon should be informed of the factors that cause the malformations and influence the growth of such patients.
Pregnancy represent a particular sistemic condition able to induce, because the tissutal metabolism is upset, an increase replay of the gingival tissues, caused by local factors as plaque and tartar. In this study are described effects determined from the increment ormone on the periodontal tissues, the alterations of the salivar components in pregnancy and the therapy to follow to reach as soon as possible the recovery.
