The patients were treated by senior students of the Dental School under the supervision of specialized personnel. The conservative treatment consisted of oral hygiene instructions and repeated instrumentation (scaling and root planing) for a period of about 3 months. Seventeen patients with advanced periodontitis participated in the study. The following data were recorded: 1. Gingival index (Silness and Löe, 1963), 2. Plaque index (Löe and Silness 1964), 3. Bleeding on probing and 4. Pocket depth and probing attachment level. The measurements were taken by the same examiner four times, that is at baseline, immediately after completion of the conservative therapy, 6 months and 12 months after treatment. Measurements from single and multi-rooted teeth were divided into three groups with respect to the initial pocket depth (less than or equal to 3 mm, 4-6 mm, greater than or equal to 7 mm). The findings of the present study demonstrated that non-surgical therapy can achieved a marked reduction in bleeding on probing scores and pocket depth 12 months after treatment. A gain in probing attachment levels was found for sites with initially deep (greater than or equal to 7 mm) and moderate (4-6 mm) pockets, while in sites with initially shallow pockets (less than or equal to 3.0 mm), a loss of attachment level was established.","PeriodicalId":75983,"journal":{"name":"Journal de biologie buccale","volume":"20 1","pages":"11-7"},"PeriodicalIF":0.0,"publicationDate":"1992-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12690980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male Wistar rats weighing 35-40 g were assigned to three groups. One of the groups received a basal choline-deficient diet ad libitum. A second group was pair-fed with the first one and was given a basal diet supplemented with 0.35 g choline chloride/100 g of diet. The third group was fed a basal diet plus 0.35 g choline chloride/100 g of diet ad libitum and used as the normal control. Body length, renal function parameters and measurements of the mandible were recorded at the end of a 12-day period on the different diets. Food intake and body weight were recorded every day. Plasma urea and creatinine concentrations markedly increased over the first 12 days of exposure to a choline-deficient diet. Significant increases in urine volume and significant depressions in urine osmolality were also observed. The average body weight and body length gains for rats given the choline-deficient diet were lower than those of control rats. There were no significant differences between the average body weight and body length of pair-fed and normal rats. All skeletal measurements of the mandible of the choline-deficient group differed significantly from those of the control group. These differences varied between 7% and 30%. The skeletal units of the mandible of the pair-fed group did not differ significantly from ad libitum controls. This study suggests that this rat model can be used for the investigation of the different alterations observed in uremia.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":75983,"journal":{"name":"Journal de biologie buccale","volume":"20 1","pages":"19-23"},"PeriodicalIF":0.0,"publicationDate":"1992-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12690981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its diagnosis is essentially histopathological showing the presence of ghost cells associated with narrow squamous epithelium, the basal strata of which consist of clearly delineated cells differentiating in areas of the stellate reticulum in a similar way to ameloblastoma. The results of ultrastructural observations of the ghost cells as well as histochemical and immunohistochemical studies suggest that they are the sites of abnormal keratinisation. The aim of this study of one COC mas to locate the stages in epithelial maturation associated with the formation of ghost cells. Six monoclonal antibodies were used; three with a wide spectrum (KL1, AE3, AE1), two with a narrow spectrum against high molecular weight cytokeratins (AE2, AE8) and one against vimentin (M725). Histopathological examination of the COC revealed three different types of cells in the epithelial lining and the epithelial islands; small basal cubic cells surrounding larger ones placed centrally or suprabasally; balloon shaped cells or flattened ghost cells rolled up on themselves to resemble keratinising pearls, or cornifying cells. The ghost cells and cornifying cells had an altered distribution of their cytokeratins demonstrated by the absence of staining of antibodies against cytokeratins. The differentiated cells adjacent to them showed cytokeratins typical of squamous epithelium rather than those associated with the process of keratinization. The coexistence of cornifying and ghost cells testifies to the great potential of odontogenic epithelium to form numerous epithelial islands.","PeriodicalId":75983,"journal":{"name":"Journal de biologie buccale","volume":"19 4","pages":"319-28"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12887776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two month longitudinal study was performed using the tissue from buccal marginal gingival biopsies of four subjects taken sequentially at five specific times: before and during plaque accumulation, and during plaque elimination. The sites examined microscopically were the coronal half of the junctional epithelium and the underlining infiltrated connective tissue fraction. No clinical change could be observed during the study period. Histological examination showed reversible cellular changes during the accumulation of plaque. There were increases in vascularization and cellularity and loss of collagen. They recovered 56 days after plaque elimination their baseline level. Electron microscopic examination showed myofibroblastic aspects in some fibroblasts. The changes in the expression of laminin, fibronectin and KL1 in the J.E. might be due to a proliferation rate enhancement, and suggest an adaptation to the alterations brought about by the inflammatory process. They also reinforce the hypothesis that this epithelium resembles a developmental tissue. Type I collagen demonstrated the \"collagen loss-repair\" cycle shown in connective tissue by the histological study. The rise in type III collagen and the vimentin fall, both at the initial stage, suggest that these protein profiles may yield information for clinical research purposes during the very early inflammatory process. The variations in fibronectin indicate its key role in the early inflammatory and repair processes. Finally, the variations in matrix and cytoskeletal proteins variations, as well as the morphological modifications observed, were nearly all reversible.","PeriodicalId":75983,"journal":{"name":"Journal de biologie buccale","volume":"19 4","pages":"329-41"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12888319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
