摘要:

AbstractThis study was undertaken to determine the prevalence of demographic and clinical factors of patients diagnosed as having ANUG as determined by the presence of painful, bleeding, necrotic and ulcerated interproximal gingival papillae. Results showed that ANUG patients were evenly divided between males and females relative to the general clinic population. 58% of the patients with ANUG were under 25 years of age as compared to 31 % under 25 in the general clinic population. Overall, the ANUG group accounted for 1.4% of the under 34 age group in the general clinic population. 76% of the ANUG group had a high school education or less with 67 % having less than $5,000 annual income. Only 20% presented with elevated temperature. Only 6% of the patients with ANUG were non‐smokers as compared to 63% in a matched control group. Of great significance was the fact that only 1 patient with ANUG was black as compared to a 41% black population in the clinic populatio

摘要:

AbstractThe present study was designed to examine whether new attachment forms on root surfaces previously exposed to plaque by preventing the oral epithelium and the gingival connective tissue from participating in the process of healing following treatment.4 roots in each of 3 monkeys were used as test units while the roots of contralateral teeth served as controls. A surgical procedure was first used to expose the coronal half of the buccal root surfaces. Plaque was allowed to accumulate on the exposed surfaces for a period of 6 months. Subsequently, soft tissue flaps were raised and the root surfaces were carefully scaled and planed. The crowns of the test and control teeth were resected and the mucosal Haps were repositioned and sutured in such a way that the roots were properly covered. Immediately prior to suturing, membranes (Millipore® filter or Gore‐tex® membrane) were placed over the denuded root surfaces of the test teeth in order to prevent granulation tissue from the soft tissue flaps from reaching the roots during healing. The monkeys were sacrificed 3 months later. The jaws were removed and histological sections of test and control roots including their periodontal tissues were produced.New cementum with inserting collagen fibers was observed on the previously exposed surfaces of both test and control roots. However, the test surfaces exhibited considerably more new attachment than the control surfaces, indicating that the placement of the membrane favoured repopulation of the wound area adjacent to the roots by cells originating from the periodontal ligam

摘要:

AbstractThe aim of the present investigation was to evaluate the periodontal conditions of a group of patients who, following active treatment of extremely advanced periodontal disease, had been maintained for 14 years in a well‐supervised maintenance care program. The present sample included 61 subjects out of an initial group of 75 individuals who in 1969 were referred to and treated by the authors. Following an initial examination, the patients were given detailed instructions in proper plaque control measures and were subjected to scaling and root planing and surgical elimination of pathologically deepened pockets. After the termination of the active treatment phase, the patients were placed in a maintenance care program including recall appointments every 3–6 months. At the initial examination, immediately after the completion of the active treatment phase and then once a year, all patients were examined regarding oral hygiene, gingival conditions, probing depths and clinical attachment levels. In addition, the interproximal alveolar bone height was determined from full mouth radiographs obtained before active treatment, at the completion of active therapy and 1, 3, 5, 8, 10, 12 and 14 years after treatment.The results from the repeated examinations demonstrated that treatment of advanced forms of periodontal disease resulted in clinically healthy periodontal conditions and that this state of “periodontal health” could be maintained in most patients and sites over a period of 14 years. It was also demonstrated that the treatment and maintenance programs described were equally effective in young and older patients.The individual mean values describing probing depths, attachment levels, and bone heights did not vary significantly over the 14 years of observation. A more detailed analysis of the data revealed, however, that a small number of sites in a few patients lost a substantial amount of attachment. This attachment loss occurred at different time intervals during the course of the maintenance period. Thus, 43 surfaces in 15 different patients were exposed to recurrent periodontal disease of a significant magnitude. This recurrent inflammatory periodontal disease caused the loss of 16 teeth in 7 different patients during the maintenance period. The data reported question the validity of using individual mean values to describe alterations of the periodontal conditions during maintenance following active periodontal

摘要:

AbstractIn the present investigation, the frequency and severity of periodontal disease was assessed in a group of patients with multiple sclerosis receiving corticosteroid hormone therapy for neurological disease. Age‐matched patients with multiple sclerosis but without hormone therapy as well as healthy subjects served as controls. Individuals suffering from multiple sclerosis or polyneuropathies were selected from a pool of patients who were under treatment at the Department of Neurology, The Central Hospital of Kuopio, Finland. 27 individuals were identified who had received more than 1.5 g prednisonc over a 1–4 year period. The average amount of steroid given to these patients was 3.5 g. 26 individuals also suffering from neurologic disease had received no or only negligable amounts of hormone therapy and were used as diseased controls. Another control group comprised age‐ and sex‐matched healthy individuals from the city of Kuopio.The dental examination which was performed by one dentist comprised assessments of the following parameters: oral hygiene status, gingival conditions, probing depth, gingival recession and height of the alveolar bone. The findings clearly demonstrated that patients with neurological disease who received corticosteroid therapy had the same frequency of gingivitis as non‐treated diseased controls. Furthermore, data describing probing depth, gingival recession and height of the alveolar bone revealed that there was no difference regarding the frequency and severity of periodontal disease between the 2 groups of neurological diseased patients. It was concluded that corticosteroid therapy maintained over 1‐4 years had no obvious influence on clinical parameters of periodontal disease in patients suffering from neurologi

摘要:

Abstract1016 textile workers were examined during a baseline study in 1969/70. A follow‐up examination in 1979/80 identified 82 subjects who had not been treated for periodontal disease in the intervening period. There were 39 male and 43 female subjects; the average age at the initial examination was 27.0 years. There was an average tooth loss of 2.5 (SEM 0.6) teeth per subject over the 10‐year period. While periodontal disease was significantly related to oral hygiene at the outset, neither factor was significantly related to the degree of tooth loss.A detailed analysis of the dynamics of the periodontal condition was undertaken. The subsequent results are presented in the form of transition matrices and clearly illustrate both the progression of periodontal disease and the degree of tooth loss associated with each level of periodontal disease at the initial examination.The main findings are as follows.(a) Overall 6% of teeth initially free of periodontal disease (P.I.O.) were lost compared to 14% with destructive periodontal disease (P.I.6).(b) Progression of periodontal disease was slow for teeth initially free of periodontal disease and with mild gingivitis (P.1.0 and P.I.1) for all age groups. However severe gingivitis (P.1.2), resulted in more rapid deterioration of the supporting tissues in subjects over 35 years old at the final examination; 35% of such teeth changed to destructive periodontal disease (P. 1.6) compared to 17% of corresponding teeth for the under 35‐year age group. In contrast, a poorer prognosis was found for the teeth with destructive periodontal disease (P.1.6) in the younger age group.(c) While the rate of progression of established periodontal disease was similar for anterior and posterior teeth, the onset of gingivitis was more pronounced in the l

摘要:

AbstractHuman teeth extracted because of advanced periodontal disease were obtained. The portions of the roots which had been exposed in periodontal pockets were either untreated or were treated with root planing or citric acid, or root planing followed by citric acid. Human gingival fibroblasts were then added to the roots so treated and were allowed to incubate for 72 h. The ability of cells to attach to and grow onto these roots was assessed by means of gross evaluation of staining intensity and by histologic and scanning electron microscopic observation. The results of multiple experiments in each root‐treatment category indicated that only roots which had been planed, whether or not citric acid demineralization was used, promoted cell attachment and growth. In addition, there were no discernible morphologic differences in the cells which were plated onto roots which were root planed only, compared to those which were root planed and citric‐acid treated. In both situations too, the cells displayed morphology typical of human gingival fibroblasts in cult

摘要:

AbstractThe paper presents 2 cases of “spontaneous” repositioning of anterior teeth following periodontal surgery. In view of the reported cases, the present approach to orthodontic treatment of periodontal patients is questioned. It is suggested that the subject of “spontaneous” repositioning deserves more attention and that documentation and research are needed to elaborate on the subject in order to establish a sound approach to orthodontic intervention in periodonta
