AbstractThe periodontal health of 30 adult epileptic patients treated with cither sodium valproate or phenytoin was compared with a control group (n= 15) of otherwise healthy patients. The 3 groups were matched for age and sex. Patients on phenytoin therapy showed significantly higher plaque scores (p<0.05), gingival index (p<0.05) and pocketing (P<0.05) than patients in the control group. The % of gingival hyperplusia was significantly higher (P<0.05) in the phenytoin‐treated patients than those on sodium valproate or in the control group. However, patients on phenytoin therapy had significantly less bone loss than those on sodium valproale (p<0.05) or in the control group (P<0.01). No significant differences were observed between the sodium valproate group and the control group on any of the parameters assessed. The results from this study would suggest that sodium valproate has no unwanted effects on periodontal health and may be considered a safe alternative, regarding the periodontal aspects, to phenytoin for the treatment of adult onset epileps

摘要:

AbstractTo determine the effect on periodontal health of a daily self‐administered irrigation with 0.02% stannous fluoride (SnF2) solution, 28 subjects who had moderate to advanced periodontitis were randomly divided into 3 groups: a control group (n= 9) which used no irrigation, a group (n= 8) which used a self‐administered water irrigation device (Water Pik) daily with water (H2O group) and a group (n=11) which used the Water Pik in a similar manner but with SnF2solution (SnF2group). All subjects were instructed in routine tooth brushing and flossing but received no other periodontal treatment. 4 study sites were selected from each patient which had pocket depths greater than 4 mm and bleeding upon probing.Plaque index, gingival index, bleeding tendency, pocket depth, loss of attachment, and microbiologic samples of subgingival plaque for morphologic determinations were collected from all study sites at baseline, 2, 6, and 10 weeks. A cross‐over was then initiated for 2 additional monthly checks in which the H2O group changed to SnF2and the SnF2group was divided into 2 subgroups which either continued to use SnF2or changed to H2O. The control group completed the study at the beginning of the crossover.The clinical data showed significantly more improvement in periodontal health during the first 10 weeks for the SnF2group (p<0.01). After cross‐over, the clinical data indicated the group that changed from H2O to SnF2significantly improved their periodontal health, while the group that changed from SnF2to H2O became worse. The microbiologic data showed trends which agreed with the clinical data during the first 10 weeks but were less significant. After cross‐over, the %s of motile rods and spirochetes were too small (0–7%) to establish statistically significant changes considering the accuracy of the tec

摘要:

AbstractIncisors, cuspids and premolars in 49 patients with advanced chronic periodontitis were treated with initial, nonsurgical periodontal therapy. The results were monitored by probing attachment level measurements for 6 sites of each tooth every 3rd month during a period of 24 months. Amongst sites with initial probing depth ≥ 4.0 mm, sites with probing attachment loss were identified using regression analysis. Scores for plaque, bleeding, suppuration on probing and probing depth, obtained for these sites during the 24‐month study, were analyzed to determine whether any of the scores could be used diagnostically as an indicator of probing attachment loss. Diagnostic sensitivity and predictability were calculated for different levels of each of the scores. The results showed that sites with probing attachment loss were more frequent for sites with high scores for plaque, bleeding, residual probing depth and suppuration than in sites with low scores. However, the diagnostic sensitivity and predictability of these clinical indicators was generally low. Thus, records of plaque, bleeding, suppuration and probing depth do not obviate the need for probing attachment level measurements for identification of sites with probing attachment loss following initial, nonsurgical periodontal ther

摘要:

AbstractThe present study was performed to determine whether the healing of periodontal intraosseous defects could be improved through the combined use of citric acid conditioning of the root surfaces and grafting of autogenous intraoral cancellous bone. 28 proximal defects in 19 patients were treated surgically including acid conditioning of the root surfaces. Another 25 defects in these patients were treated with acid conditioning combined with osseous grafts using the maxillary tuberosity areas as donor sites.Both therapies, e.g., citric acid conditioning alone and acid conditioning combined with osseous grafting resulted in approximately 1 mm gains of probing attachment and probing bone levels. Within the parameters of this study, osseous grafting did not enhance the effect of citric acid conditioning alone. Limited improvement of the treated defects of the present study was obtained in spite of the use of supplementary regenerative techniques.

摘要:

AbstractThis study reports on the pattern of interradicular bone formation and the frequency and localization of ankylosis following regenerative surgery of experimentally‐induced furcation defects in 12 beagle dogs. Observations were made in 39 specimens showing healing with connective tissue attachment in the full circumference of the furcation. The findings indicate that bone regeneration first occurs adjacent to the root surfaces, followed by a subsequent fill of the central portion of the interradicular area. Ankylosis, observed in 24 of the 39 specimens, was more frequent in large defects than in small defects. The incidence of ankylosis increased with increased distance from the base of the original wound. These findings suggest that coronal bone apposition may require or be facilitated by the presence of a root surface, and that undisturbed coronal regeneration may be dependant upon cellular or sonic other activity from the intact periodontal ligamen

摘要:

AbstractSinceActinobacillus actinomycetemcomitansappears to be a key etiologic agent in localized juvenile periodontitis, this study determined the effectiveness of different treatment modalities in suppressingA. actinomycetemcomitansin localized juvenile periodontitis lesions. A total of 25 deep. periodontal lesions from 7 patients with localized juvenile periodontitis were included in the study. The test periodontal lesions either received scaling and root planing alone, scaling and root planing together with soft tissue curettage, or modified Widman (lap surgery. SubgingivalA. actinomycetemcomitanswere enumerated using selective culturing. Clinical measurements included changes in probing periodontal attachment level, probing periodontal pocket depth, gingival index, plaque index, and digital subtraction of standardized serial radiographs. The microbiological and clinical effects of treatment were monitored over a period of 16 weeks.All periodontal lesions studied demonstrated high numbers ofA. actinomycetemcomitansprior to treatment. Scaling and root planing alone did not markedly change the subgingivalA. actinomycetemcomitanscounts, nor any of the clinical parameters studied. In contrast, soft tissue curettage as well as modified Widman flap surgery suppressedA. actinomycetemcomitansto undetectable levels immediately after therapy in more than 80% of the lesions studied. A total of 5 periodontal lesions exhibited gain of probing periodontal attachment after subgingival curettage or Widman flap treatment; 3 of these sites revealed no detectableA. actinomycetemcomitans, and the remaining 2 sites harbored only low levels ofA. actinomycetemcomitans.5 periodontal lesions which lost probing attachment after treatment all demonstrated high numbers of subgingivalA. actinomycetemcomitans.Changes in alveolar bone, assessed by digital subtraction of serial radiographs, correlated with changes in probing periodontal attachment level, confirming the clinical results.The present study revealed a close relationship between post‐treatmentA. actinomycetemcomitanslevels and the clinical response to treatment, which supports the concept thatA. actinomycetemcomitansis an important organism in the etiology of localized juvenile periodontitis. This study also showed that a substantial suppression of subgingivalA. actinomycetemcomitanscannot be achieved by periodontal scaling and root planing alone, but can be accomplished by surgical removal of periodontal tissues. However, the predictability of surgical procedures in suppressing subgingivalA. actinomycetemcomitanswas poorer than that obtained in a previous study in which systemic tetracycline was used without concomitant periodontal surger

摘要:

AbstractThe temperature changes of the labial gingiva and mucosa of the maxillary incisor regions were investigated using computer‐assisted thermography. 9 patients with destructive periodontal disease (7 female and 2 male, aged between 12 and 33 years, undergoing periodontal treatment for periods varying from 6 months to 12 years) and 10 volunteers with clinically normal periodontia (6 female and 4 male, aged between 19 and 26 years) took part in this study. The gingivae and mucosae were initially cooled using a homogenous flow of air (15 1/min at 15deg;C) for 3 min. 20 s after the cooling phase, temperature increases of these soft tissues were sequentially recorded using 48 thermograms per person. This procedure was repeated 4 times for each person examined. The weighted mean of the time constants of the tissue re‐warming curves was significantly higher (p<0.025) for the periodontitis group (152 ± 6 s) compared to the clinically healthy group (110 ±9 s). The different thermodynamic behaviour between the 2 groups studied indicated differences in the blood‐flow and/ or its reg

摘要:

AbstractThe aim of the present investigation was to evaluate the oral hygiene habits and the periodontal conditions of a group of cleft lip, alveolus and palate patients at the end of a longitudinal multidisciplinary treatment. From a total of 120 patients who had been supervised at the University of Berne, Clinic for Pediatric Surgery for at least 18 years in a co‐ordinated team approach, 80 were selected on the basis of availability. Plaque control record (PCR), calculus index (CI), gingival bleeding index (GBI), pocket probing depth (PD), loss of attachment (LA) and furcation involvement were recorded. Using the technique and the ruler described by Schei et al., the radiographic height of the alveolar crest from the cemento‐enamel junction was determined.Between the different groups of deformities, no statistically significant differences were found for all the clinical parameters with the exception of the mean PD orally and the mean PD bucally which were shallower in the isolated cleft lip group. These differences were attributed to the long‐term orthodontic therapy with fixed appliances.When the PD and the LA at the sites adjacent to the cleft region were compared to two “unaffected” control sites, no statistically significant differences were found, whereas the comparison with the radiographic bone loss showed a statistically significant lower bone height. These results may indicate the presence of a long connective tissue attachment without bony support in the cleft region.As a result of inadequate oral hygiene, the patients with cleft lip, alveolus and palate showed beginning periodontitis with loss of attachment and beginning furcation involvement in most of the cases. Since these patients need long‐term orthodontic therapy with fixed appliances, they should be incorporated in intensive prophylaxis programs as early in age
