AbstractThe periodontal status of 85 12–18 year‐old Finnish adolescents with insulin‐dependent diabetes mellitus (IDDM) and their paired, age‐ and sex‐matched healthy controls was assessed clinically and radiographically. The clinical examination consisted of plaque index, gingival index (GI), retentive calculus index, WHO community periodontal index of treatment needs, number of pockets ≥4 mm and number of surfaces bleeding after probing. Alveolar bone loss was measured interproximally from the first molars in bite‐wing radiographs (all subjects) and from the first incisors in periapical X‐rays (patients only). The results show that in spite of similar plaque scores, the patients had higher GI scores and more surfaces bleeding after probing. No differences were found in the number of ≥4 mm pockets or radiographical bone loss in

摘要:

AbstractThe adhesive antibiotic TA was applied to the dento‐gingival junction of 8 human volunteers, suffering from moderate to severe gingivitis. 2 diametrically opposed quadrants of the mouth received 4 applications of 0.1 mg TA, while the other 2 quadrants were treated with a placebo and served as controls. The plaque index, gingival index and bleeding index were scored periodically for 2 weeks and in 4 patients for up to 30 days. The TA‐treated quadrants showed a rapid decrease in all 3 indices following 2 treatments. A further improvement was observed with the 3rd and 4th treatments. 30 days after the onset of the experiment and 23 days after the last application, the indices were still considerably lower than the initial val

摘要:

AbstractThe prevalence of early periodontal destruction was assessed in a group of 516 14‐year‐old Iraqi schoolchildren who had not been offered public dental care programmes. Vertical bone loss adjacent to the proximal surfaces of first molars was used to indicate an incpient periodontal lesion, and the prevalence of subjects diagnosed as having one or more sites with this criterion in the Iraqi group was compared with those of 2 Scandinavian populations of the same age. These comprised 241 Norwegians who had received regular dental care and 561 Danes with or without such programmes. In the Iraqi group. 11.5% showed 1 or more sites with radiographic bone loss. However, few sites exhibited deep defects. There were significantly fewer Norwegian teenagers showing early periodontal lesions as compared to the Iraqi group (p<0.01) and the Danish subjects with no school dental programmes (p<0.01). Danish teenagers receiving regular dental care did not differ from the Norwegian group. It was concluded that the criterion used in the present study seems suitable for detecting differences in the prevalence of incipient radiographic periodontal lesions among young populations, and that the utilization of public dental care services may be an important factor in explaining such differen

摘要:

AbstractA 6‐month, double‐blind controlled study was conducted on 101 subjects to determine the effect of Perimed1Rantibacterial system, containing povidone‐iodine (PVP‐I) and hydrogen peroxide (H2O2). on established gingivitis. Subjects were randomly assigned to one of 4 treatment groups: PVP‐I/H2O2, PVP‐I/H2O2H2O2/H2O or H2O. Gingivitis was assessed by the papillary bleeding score (PBS) and plaque by a modified Quigley‐Hein plaque index (PI) at baseline, 3, 12 and 24 weeks. The average baseline PBS and PI for the 4 groups ranged from 2.16–2.31 and 2.87–2.90, respectively. After baseline evaluation, subjects received a supra‐gingival scaling and a subgingival irrigation with their respective rinse. Daily rinses were supervised and subgingival irrigation was repeated every 3 weeks. Duncan's multiple range test determined which groups differed from each other. The mean PI at 24 weeks was lower than at baseline in all groups. PVP‐I had the lowest PI at all time points. The mean PBS at 24 weeks was 1,48 for PVP‐I, 1.62 for H2O2, 1.88 for H2O and 1.34 for PVP‐I/H202, a reduction from baseline of 31%, 27%, 18%, and 38% respectively. The difference between the PBS for PVP‐I/H2O2and H2O control was significant at each evaluation. There was a 70% reduction in sites with PBS>3 for PVP‐I/H2O2between baseline and 24 weeks compared to a 34% decrease in the H2O group. It was concluded that the use of PerimedRcould be a beneficial adjunctive treatment for the prevention and control of gingivitis when used with ro

摘要:

Abstract2 intraoral lesions associated with human immunodeficiency virus (HIV) infection have recently been described: an atypical gingivitis and a rapidly progressive periodontitis. The microbiota associated with these gingival and periodontal lesions was investigated. Subgingival plaque samples were taken from 45 HIV‐seropositive homosexual men and from 44 HFV‐seronegative control subjects. Each sampled site was clinically and radiographically classified as HIV‐associated gingivitis, HIV‐associated periodontitis, healthy in an HIV‐seropositive subject, or healthy, conventional gingivitis or classical periodontitis in a control subject. Plaque samples were examined by indirect immunofluorescence with polyclonal antisera to detectBacteroides gingivalis, B. intermedius, Fusobacterium nucleatum, and Actinobacillus actinomycetemcomitans.Anaerobic culturing was used to detect black‐pigmented Bacteroides species, Fusobacterium species, and A. actinomycetemcomitans to confirm the immunofluorescence findings. We detected B. gingivalis, B. intermedius, F. nucleatum, and A. actinomycetemcomitans in significantly more HIV‐periodontitis sites (80, 65, 59 and 61 % of sites, respectively) and HIV‐gingivitis sites (61, 70, 52 and 52%, respectively) than in HIV‐seropositive healthy and control sites (p<0.05). The results indicate that the microbiota found in HIV‐periodontitis is similar to that of classical periodontitis. In contrast, however, the microbiota associated with HIV‐gingivitis is strikingly different from that of conventional gingivitis. The similarity in the prevalence of periodontopathic organisms in both HIV‐gingivilis and HIV‐periodontitis suggests that the HIV‐gingivitis lesion may be a precursor to the tissue destruction observed in HIV‐periodontitis. Hence, early detection and treatment of the HIV‐gingivitis lesion may prevent the rapid and extensive breakdown of periodontal tissues as

摘要:

AbstractThe aim of the present study was to evaluate the clinical effect of non‐surgical periodontal therapy with the adjunct of a selected antibiotic in subjects with refractory periodontitis. 10 subjects were selected for the study; all had a history of periodontal surgery, tetracycline therapy, and regular maintenance by a periodontist. Clinical registrations including gingival index, plaque index, presence of bleeding and suppuration, pocket depth, and duplicate measurements of attachment level were performed at baseline and at monthly intervals. When disease activity was detected based on the tolerance method, a bacterial sample was taken from the active site and its susceptibilities to a number of antibiotics were determined. For the selected 10 subjects, Augmentin® was the antibiotic of choice. Each subject received 750 mg/day for 2 weeks, during which time a full‐month scaling and root Planing was performed under local anesthesia. Clinical re‐evaluation was performed after 3, 6, 9 and 12 months. At the time disease activity was detected, the average loss of attachment at all active sites was 2.2 mm, and the increase in pocket depth 1.5 mm. At 3 months post‐therapy, these sites had regained 2 mm of attachment which remained stable through the 12‐month examination. Pocket depths decreased 2.5 mm over the first 6 months and then stabilized‐ The frequency of all sites that gained 1 mm or more of attachment increased by approximately 10% over the first 9 months following therapy. The frequency of all sites that decreased 1 mm or more in pocket depth increased approximately 15% over the same period. The frequency of bleeding and suppuration was low initially and did not change significantly. Plaque scores were low throughout the study. Post‐therapy, the frequency of sites with a GI score of 2–3 decreased from 13.3 to 1.9%. The results suggest that non‐surgical periodontal therapy with adjunctive use of a selected antibiotic may reduce the incidence of attachment Joss for at least 12 months in individuals who previously had been refra

摘要:

AbstractThe combined length of the supracrestal connective tissue attachment and the junctional epithelium is referred to as the “biologic width”. The long‐term (1‐year) effect of complete violation of the supracrestal connective tissue attachment was examined in beagle dogs. Full thickness periodontal flaps were elevated, exposing the buccal bony crests of the maxillary and mandibular canines of 3 beagle dogs. The roots of the experimental teeth were planed and class V cavities were prepared. The apical border of each cavity was located at the alveolar bone crest. The cavities were restored with amalgam and the flaps were repositioned and sutured. In the control sites, a notch was prepared at the CEJ and the distance between the notch and the bony crest was measured. The dogs were sacrificed 57 weeks after the operation and the experimental and control sites prepared for histologic analysis. Every 5th section was examined and measurements were taken of the amount of gingival and bone recession, the length of the connective tissue and the epithelial attachment. Control sites healed uneventfully. Gingival recession averaged only 0.5 mm; bone loss was minimal and averaged 0.15 mm. The combined length of the supracrestal connective tissue and epithelial attachment measured 4.47 mm. In experimental sites, the gingiva receded 3.16 mm on average. Moderate bone loss (x̄=1.17 mm) was noted, but no signs of bone resorption were seen at the time of sacrifice. After bone loss, root surfaces which were previously attached to alveolar bone by periodontal ligament were mainly (0.90 mm) attached to connective tissue. Mild inflammatory infiltrate was observed in the lamina propria primarily at the restoration area. It is concluded that continuous abuse of the gingival attachment results in a certain loss of the periodontal attachment apparatus. The biologic width is partially restored by a more apical location of a. reduced‐in‐size, supracrestal connective tissu

摘要:

AbstractFamilial gingival fibromatosis is generally reported to be inherited as an autosomal dominant trait. We investigated 2 families with few siblings affected with gingival fibromatosis. No linkage between HLA antigen and the phenomenon was found. These results support the idea of the autosomal dominant nature of familial gingival fibromatosis.

摘要:

AbstractAbout 300 subjects, 20–79 years of age were recruited for a longitudinal study on the effect of periodontal therapy. The result of a baseline examination have been reported earlier. Following this baseline examination, the subjects were monitored for 24 months without therapy‐ Re‐examinations were performed after 12 and 24 months. Ail teeth including the 3rd molars were included in the return for either the 1st, the 2nd or both re‐examinations. An analysis was performed regarding the periodontal status at baseline, of the respondents and non‐respondents. The results from the follow‐up examinations of the participating characteristic of periodontal disease. Thus, the mean values of probing pocket depth and probing attachment level failed to change between baseline and the re‐examinations after 1 and 2 years. Even if the mean values Underwent only minor changes, however, certain subjects within each age category improved their periodontal conditions, whereas other subjects worsened. Furthermore, the findings of the re‐examinations revealed that there was a strong correlation between improving plaque levels and gingivitis. The relationship between supra‐gingival plaque levels and changes with respect to probing depth and attachment
