Trends in surgical and nonsurgical periodontal treatment.
(1/71)
BACKGROUND: New research is demonstrating that a person's total health is indeed related to his or her oral health. Elimination of all oral infections, including gingivitis and periodontis, is important to overall health. CLINICAL IMPLICATIONS: This article reviews recent evidence on the systemic and oral connection and discusses these findings as they relate to patient care. The article examines trends in nonsurgical and surgical therapy that will successfully arrest periodontal infections. Opportunities for early diagnosis and prevention will play an increasing role in dental practice in the future as patients understand the importance of oral health to overall health. (+info)
Gingival fluid ciprofloxacin levels at healthy and inflamed human periodontal sites.
(2/71)
BACKGROUND: Polymorphonuclear leukocytes (PMNs) take up and accumulate ciprofloxacin. This may allow them to enhance the delivery of this agent to the inflamed periodontium. METHODS: Cross-sectional and longitudinal approaches were used to test the hypothesis. In the cross-sectional study, 7 periodontally healthy adults and 8 adults with untreated periodontitis were administered three doses of ciprofloxacin (500 mg bid). Gingival fluid (GF) and serum samples were obtained after 28 hours and analyzed by high-performance liquid chromatography (HPLC). In the longitudinal study, 8 adult periodontitis subjects were administered 500 mg ciprofloxacin bid for 8 days. After 28 hours, GF from 4 sites with 5 to 8 mm probing depths was sampled in each subject, serum samples were obtained, and 2 of the 4 sites were root planed. GF and serum were sampled again 7 days later (196 hours after the initial dose). RESULTS: The mean ciprofloxacin levels in the GF and serum of periodontally healthy subjects were 2.52 +/- 0.22 microg/ml and 0.47 +/- 0.05 microg/ml, respectively. In subjects with periodontitis, these levels were 2.69 +/- 0.44 microg/ml and 0.61 +/- 0.13 microg/ml, respectively. GF ciprofloxacin levels were significantly higher than corresponding serum levels in healthy and diseased subjects (P<0.01), but there were no significant differences in GF or serum levels between the 2 subject groups. Since GF flow was significantly higher at diseased sites, however, more ciprofloxacin was distributed to these sites than to healthy sites. In the longitudinal study, GF flow at 196 hours was 16% lower at root planed sites than at untreated control sites (P = 0.412). The minor decrease in this index of inflammation was accompanied by a small (9%), but statistically significant (P= 0.007), decrease in GF ciprofloxacin levels. CONCLUSIONS: GF ciprofloxacin levels decreased slightly at inflamed periodontal sites after root planing, but were significantly higher than serum levels even at healthy periodontal sites. Inflammation may enhance the distribution of ciprofloxacin to diseased sites, but it is not a major determinant of GF ciprofloxacin levels. (+info)
Morphologic analysis, by means of scanning electron microscopy, of the effect of Er: YAG laser on root surfaces submitted to scaling and root planing.
(3/71)
The purpose of this study was to morphologically evaluate, by means of scanning electron microscopy, the effects of Er:YAG laser on the treatment of root surfaces submitted to scaling and root planing with conventional periodontal instruments. Eighteen root surfaces (n = 18), which had been previously scaled and planed, were assigned to 3 groups (n = 6). The control Group (G1) received no further treatment; Group 2 (G2) was irradiated with Er:YAG laser (2.94 mum), with 47 mJ/10 Hz, in a focused mode with air/water spray during 15 s and with 0.57 J/cm of fluency per pulse; Group 3 (G 3) was irradiated with Er:YAG laser (2.94 mum), with 83 mJ/10 Hz, in a focused mode with air/water spray during 15 s and with 1.03 J/cm2 of fluency per pulse. We concluded that the parameters adopted for Group 3 removed the smear layer from the root surface, exposing the dentinal tubules. Although no fissures, cracks or carbonized areas were observed, an irregular surface was produced by Er:YAG laser irradiation. Thus, the biocompatibility of the irradiated root surface, within the periodontal healing process, must be assessed. (+info)
Comparison of the effects of various periodontal rotary instruments on surface characteristics of root surface.
(4/71)
The efficacy of scaling and root planing using various periodontal rotary instruments was examined. Eighty extracted human teeth with a history of periodontal disease were divided into four groups of 20 and subjected to one of the following procedures: Use of 1) a Root Burnisher, 2) a Perio Planing Bur (both rotating instruments for contra angle handpieces), 3) a Tooth Planing Bur (rotating instrument for use with an air turbine), or 4) a Gracey Scaler. In each case, the time required for cleaning was measured. Twenty healthy extracted human teeth were used as untreated controls. After treatment, the surface roughness of 10 specimens out of each group were measured using a profilometer and observed by scanning electron microscopy (SEM). Half of the samples were then incubated in dishes with a suspension of fibroblasts. After counting the number of attached cells, the attachment of fibroblasts was observed by SEM. The root surfaces treated with the rotary instruments appeared smooth and there were no significant differences between groups. From the SEM observations, smooth root surfaces with different surface textures were evident and a tight attachment of fibroblasts was observed. The results of this study suggest that use of rotary instruments is superior for periodontal scaling and root planing. (+info)
A comparative evaluation of the clinical effects of systemic and local doxycycline in the treatment of chronic periodontitis.
(5/71)
In this study, the clinical efficacies of systemic doxycycline (SD) and local doxycycline (LD) in the treatment of chronic periodontitis were compared. Forty-five patients were studied in 3 main groups with 5 treatments: SD alone, SD+scaling-root planing (SD+SRP), LD alone, LD+SRP and SRP alone. Antibiotic-treated patients were given doxycycline treatment alone in 1 quadrant of their upper jaws, and doxycycline+SRP was given in the contralateral quadrant. The areas included at least 4 teeth with > or = 5 mm pockets. Probing depth (PD), clinical attachment level, gingival index, sulcular bleeding index and plaque index values were recorded at baseline and the 7th week. The results were statistically analyzed. All of the clinical parameters were significantly reduced by all treatments (P < or = 0.05). The SD and LD treatments alone provided significant clinical healings. The significant differences among the groups were only in PD at the 7th week. The LD treatment provided significantly higher PD reduction than the SD treatment (P < or = 0.05). No significant difference was found between the SD+SRP and the LD+SRP treatments. There was no significant difference between SD+SRP and SRP alone treatment (P > 0.05). The SD group showed lower PD reduction than SRP group (P < or = 0.05), while no significant difference was found between LD and SRP treatments. The LD alone treatment seemed more effective than SD alone treatment on PD reduction, but no significant difference was found between them when combined with the SRP. LD may be more preferable than SD as an adjunct to mechanical treatment since LD seems more effective than SD on PD reduction and does not have the side effects of SD. (+info)
Management of patients with foreign body gingivitis: report of 2 cases with histologic findings.
(6/71)
Foreign body gingivitis is an inflammation of the gingiva, characterized by foci containing particles of foreign material in the connective tissue, which can have either a granulomatous or a lichenoid microscopic appearance. In clinical terms, it differs from other immune-mediated gingival disorders in its limited involvement of tissues other than the gingiva, as well as its relative resistance to treatment by topical corticosteroids. Two cases are presented, with a review of the clinical features, including characteristic desquamation and mottling of the marginal gingiva and symptoms of localized tenderness and pain; gingival recession was observed in both of the reported cases. Histologic examination revealed damaged epithelium and degeneration of the basal layer, as well as a mixed inflammatory cell infiltrate in the connective tissue with refractile or opaque particles of foreign material. Gingival inflammation and the severity of gingival erosions improved dramatically with careful debridement, improved home care and more frequent, diligent periodontal maintenance therapy. Free gingival grafts, together with excision of affected tissues, served to stabilize and reinforce the marginal tissues, as well as eliminating further clinical signs of the disease; excision alone was not as effective. Patients require careful dental and periodontal management as well as appropriate oral home care to avoid further mechanical damage to the gingiva; in addition, the use of dental abrasives and polishing agents should be restricted, particularly if gingival lesions are present. Home care recommendations include avoidance of dentifrices with certain chemical additives and rinses with a high alcohol content. (+info)
Effects of periodontal treatment phase I on birth term and birth weight.
(7/71)
Considering the high prevalence of preterm birth (PTB) and low birth weight (LBW) and their complications as well as the role played by periodontal disease in their incidence and the lack of any report of periodontal therapy on these problems in Iran, the goal of the present research was to determine the effects of periodontal treatment on PLBW incidence among women with moderate or advanced periodontitis who were referred to Javaheri hospital (2004-2005). This clinical trial research was conducted on 30 pregnant women age ranging from 18-35 years old, with moderate or advanced periodontitis. Fifteen subjects randomly underwent the first phase of periodontal treatment including scaling, root planning and the use of 0.2% chlorhexidine mouth rinse for one week. None of these steps were taken for the controls. After necessary follow ups, the effect of periodontal treatment on birth term and birth weight were analyzed statistically. This research was conducted on 30 subjects, 15 controls and 15 cases in study group. In the control group, the observed rate of PLBW was 26.7% whereas among periodontally treated group, phase I, PLBW infant was not observed (P < 0.05). Infants birth weight were (3059.3-389.7) gms in study group and (3371-394.2) gms in the control group and respectively (P < 0.05). Periodontal therapy, phase I, results in a reduction in PLBW incidence rate. Therefore, the application of such a simple method among periodontally diseased pregnant women is recommended. (+info)
Scanning electron microscopic analysis of the effect of Carisolv gel on periodontally compromised human root surfaces.
(8/71)
The aim of this study was to analyze, under scanning electron microscopy (SEM), the morphologic characteristics of root surfaces after application of Carisolv gel in association with scaling and root planing (SRP). Sixty periodontally compromised extracted human teeth were randomly assigned to 6 groups: 1) SRP alone; 2) passive topical application of Carisolv + SRP; 3) active topical application of Carisolv + SRP; 4) multiple applications of Carisolv + SRP; 5) SRP + 24% EDTA; 6) topical application of Carisolv + SRP + 24% EDTA. Carisolv gel was applied to root surfaces for 30 s, followed by scaling and root planing, consisting of 50 strokes with Gracey curettes in an apical-coronal direction, parallel to the long axis of the tooth. The only exception was group 4, in which the roots were instrumented until a smooth, hard and glass-like surface was achieved. All specimens were further analyzed by SEM. The results showed that the treatment with Carisolv caused significant changes in root surface morphology of periodontally compromised teeth only when the chemical agent was actively applied (burnishing technique). Carisolv failed to remove the smear layer completely, especially with a single application, independently of the method of application. Multiple applications of Carisolv were necessary to achieve a smear layer reduction comparable to that obtained with 24% EDTA conditioning. (+info)
