Surgical versus non surgical treatment and recurrent periodontal disease in beagle dogs

The present study was designed to compare clinical, microbiologic and histometric parameters of recurrent periodontal disease in areas which had been treated either surgically (SU) or nonsurgically (NS). Periodontal disease was induced for 6 months in 3 quadrants in each of 6 beagle dogs. 2 of the 3 diseased quadrants were treated by definitive surgical or nonsurgical therapy followed by plaque control for 4 months. 2 dogs were then sacrificed to provide histometric data. Periodontal disease was reinduced in the remaining 4 dogs by allowing plaque accumulation for 6 months after which the dogs were sacrificed for histometric analysis. Clinical parameters were recorded and darkfield microscopic analysis of subgingival plaque samples was performed at regular intervals. Following 6 months of plaque accumulation during disease reinduction, there were significant changes (p less than 0.05) in the pocket depths, bleeding scores and attachment levels in both the SU and NS areas. These changes were accompanied by significant increases (p less than 0.05) in the proportions of spirochetes and motile rods and decreases in the proportions of coccoid cells in both the SU and NS areas. There were, however, no significant differences between the SU and NS areas when clinical and microbiologic parameters were compared. At the end of disease reinduction phase, the length of inflammatory cell infiltrate and % inflamed connective tissue had increased significantly in both the SU and NS areas.(ABSTRACT TRUNCATED AT 250 WORDS)     

C-reactive protein in patients with coexistent periodontal disease and acute coronary syndromes

AIM: To evaluate periodontal disease (PD) influence on changes in high-sensitivity C-reactive protein (hsCRP) concentrations in patients with acute coronary syndromes and coexistent PD. MATERIALS AND METHODS: Dental examinations were carried out in a group of 50 consecutive patients, less than 60 years old, hospitalized as a result of acute coronary syndromes. The patients were divided into two groups on the basis of own-constructed combined PD score (group 2: more advanced; and group 1: less advanced PD) as well as clinical attachment loss (CAL) - group 4: CAL >3 mm; group 3: CAL 相似文献   

C-reactive protein as a marker of periodontal disease

Periodontal subgingival pathogens affect local and systemic immune and inflammatory response and cause the release of cytokines; this results in periodontal destruction and initiation of an acute phase systemic inflammatory response characterized by the release of C-reactive proteins (CRP). This study set out to evaluate the serum concentration of CRP that can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular disease. Based on their periodontal status, 45 patients were divided into three groups. The following clinical parameters were recorded: plaque index, gingival index, bleeding index, probing pocket depth, and clinical attachment levels. Scoring was done on six tooth surfaces for all teeth. For the CRP assessment, blood samples were collected from subjects at the time of clinical examination. The results indicated an increase in serum CRP levels in patients with generalized aggressive periodontitis and chronic periodontitis as compared to controls.

Effect of non-surgical periodontal treatment with or without doxycycline on the periodontium of type 1 diabetic patients

AIM: The present investigation was performed to study how type 1 diabetics responded to non-surgical periodontal treatment with and without adjunctive doxycycline. METHOD: Sixty diabetic type 1 patients (mean age 35.3+/-9 years) with moderate-to-severe periodontal disease were selected and divided into two groups of 30 patients each. Both groups were sex and age matched and had similar amounts of periodontal destruction. Plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment levels (CAL) were recorded. Group 1 (30 patients) was treated with oral hygiene instruction, scaling and root planing, chlorhexidine rinses twice a day and doxycycline (100 mg/day for 15 days). Group 2 (30 patients) had the same treatment but without doxycycline. After 12 weeks their periodontal condition was reevaluated. RESULTS: After treatment, both groups had a significant improvement in all periodontal parameters, since PI, BOP, probing pocket depth (PPD) and CAL were significantly reduced. However, the reduction in PD in pockets > or =6 mm and in BOP were more evident when doxycycline was used (group 1). Differences between groups for these parameters were statistically significant (p=0.03). CONCLUSION: Although both periodontal treatment regimens are effective in type 1 diabetics, the use of doxycycline as an adjunct, provided more significant results when good plaque control was achieved.     

The relationship between periodontal disease and blood glucose level among type II diabetic patients

The aim of this study was to determine the relationship between periodontal disease and the blood glucose level among type II non-insulin dependent diabetic mellitus (NIDDM) subjects. Forty subjects, 20 in each group, of healthy and diabetic subjects, ages ranged 20-70 years, were examined at King Saud University, College of Dentistry. Clinical examination included frequency of oral hygiene practices, periodontal status by using the Community Periodontal Index of Treatment Needs (CPITN), fasting blood glucose level (FBGL), and random blood glucose level (RBGL). Unstandardized orthopantomograms (OPGs) were taken for radiographic findings. The number of missing teeth (tooth loss) was assessed from the radiographs. The results showed that periodontal disease severity was high among diabetic subjects. Diabetic subjects brushed less frequently, and they had a higher blood glucose level than healthy subjects. The mean CPITN score was compared with mean blood glucose level and the severity of periodontal disease. There was a steady increase in blood glucose level with increase in CPITN scores, i.e., CPITN score 13.5 to 19.12 corresponded with 142 mg/dl and 173.2 mg/dl FBGL, and 184.2 and 199.12 mg/dl RBGL among diabetic subjects. The study indicated that diabetic subjects should improve their oral hygiene practices and control of blood glucose levels should be emphasized. Further studies are needed among diabetics and healthy subjects from the general population with better sampling techniques and a larger sample size.     

牙周支持治疗对维持基础治疗长期效果的作用

目的 观察牙周支持治疗对维持基础治疗长期效果的作用。方法 对在口腔医院接受过牙周治疗的患者进行回顾性研究,其中接受支持治疗16例,未接受支持治疗14例（对照组）。牙周临床检查包括牙周袋探诊深度(PD)、探诊出血(BOP)阳性位点(+),比较初诊,6周复诊以及最后一次复诊时的上诉各项临床检查指标。结果 6周复查时两组的PD和BOP(+)位点百分比明显降低,差异无统计学意义。最后一次复诊时支持治疗组的PD为2.83 mm,BOP(+)位点百分比为15.49%,与初诊比较差异有统计学意义;而对照组的PD为3.51 mm,BOP(+)位点百分比为60.42%,与初诊比较差别无统计学意义,与支持治疗组比较差别有统计学意义。结论 牙周基础治疗可以有效控制牙周炎症,但是其炎症控制的长期效果需要通过支持治疗来维持。     

Healing following surgical non-surgical treatment of periodontal disease

Abstract A clinical trial was undertaken to study the effect of one surgical and one non-surgical treatment modality in patients with advanced periodontal disease. Fifteen patients were selected for the study. Following a Baseline examination comprising assessments of oral hygiene status, gingival conditions, probing depths and attachment levels, all participants were subjected to treatment. In each patient, scaling and root planing were carried out in conjunction with the modified Widman flap procedure in two jaw quadrants while in the contralateral quadrants the treatment was restricted to scaling and root planing. During the phase of active treatment, i.e. the period between the first and last operation, and for the subsequent 6 months of healing, the patients were subjected to “professional toothcleaning” once every 2 weeks. From this time until the end of the trial which was 24 months after active treatment, the patients were recalled for prophylaxis once every 3 months. Reexaminations were performed 6, 12 and 24 months after the completion of active treatment. The results demonstrated that scaling and root planing used alone were almost equally effective as their use in combination with the modified Widman flap procedure in establishing clinically healthy gingiva and in preventing further loss of attachment. Both treatment modalities prevented recurrence of periodontal disease for the 24 months of observation. The analysis of the probing depth data revealed that both methods of treatment resulted in a high frequency of probing depths of <4 mm. The probing depth reduction was more pronounced in initially deep than in initially shallow pockets and, for initially deep pockets, more marked in sites subjected to surgery than in sites exposed to scaling and root planing alone. The measurements also showed that sites with initially deep pockets exhibited more pronounced gain of clinical attachment than sites with initially shallow pockets. Significant loss of attachment did not occur in sites treated with scaling and root planing alone while attachment loss was found following Widman flap surgery in sites with initial probing depth of <4 mm.     

CPITN assessment of periodontal disease in diabetic patients

The aim of this study was to investigate, using the CPITN system, the periodontal treatment needs in diabetic patients, and to shed additional light on the possible effects of the duration and control of diabetes on the periodontal status in these patients. A comparison was made between 222 diabetic patients (mean age, 46.9 years) and 189 control subjects (mean age, 43.9 years). Edentulous patients were not included in the study. The results indicated that diabetic patients demonstrated significantly more missing teeth (P less than 0.001). The mean number of missing sextants was also significantly higher in diabetics. Pathologic pockets of 6 mm or more were found in 1.3 and 0.3 sextants in the diabetic and control group subjects, respectively (P less than 0.001). Up to the age of 34, no differences were observed between the diabetic and control group subjects regarding pathologic pockets of 6 mm or more. Above this age, diabetics demonstrated significantly more sextants with deep pockets (P less than 0.001). Concerning the type of diabetes, no differences related to CPITN score were found between insulin dependent and non-insulin dependent diabetics. Neither were any differences found in the periodontal condition related to the duration and control of diabetes, whereas diabetics with advanced retinopathy demonstrated more sextants with deep pockets. Oral hygiene instructions and scaling were required in all patients from both study groups. On an average, 1.3 sextants in 50.9% of diabetics and 0.3 sextants in 17.9% of control subjects required complex treatment.     

Effect of periodontal treatment on the C-reactive protein and proinflammatory cytokine levels in Japanese periodontitis patients

BACKGROUND: Recent epidemiological studies have shown that individuals with periodontitis have a significantly increased risk of developing coronary heart disease. In addition to conventional risk factors, chronic infection and subsequent production of systemic inflammatory markers may be associated with this increased risk. OBJECTIVES: The aim of the present study was to determine whether the presence of chronic periodontitis and subsequent periodontal treatment could influence the serum levels of C-reactive protein (CRP), interleukin-6 and tumor necrosis factor-alpha (TNF-alpha) in a Japanese population. METHODS: Sera were obtained from 24 patients with moderate to advanced periodontitis at the baseline examination and at reassessment after completion of treatment. As a control, sera were also obtained from 21 subjects without periodontitis. High-sensitivity CRP (hs-CRP) was measured using nephelometry with a latex particle-enhanced immunoassay and interleukin-6 and TNF-alpha were determined by sensitive enzyme-linked immunosorbent assay. RESULTS: The levels of hs-CRP and interleukin-6 in the sera of this Japanese population seemed to be much lower than those reported in other populations. TNF-alpha on the other hand, demonstrated similar levels between this Japanese and other populations. Periodontal status demonstrated a significant improvement in all patients following treatment. There was a trend toward higher hs-CRP levels in patients at baseline compared with control subjects. Hs-CRP level tended to decrease with improvement of the periodontal condition following treatment and approached that of control subjects, although this decline was not statistically significant. interleukin-6 and TNF-alpha levels did not change following periodontal treatment. Furthermore, there was no difference in the serum levels of these inflammatory cytokines between patients either at baseline or at reassessment and control subjects. CONCLUSIONS: In this pilot study, we were unable to show that periodontal disease significantly affects the serum levels of systemic inflammatory markers. However, this does not necessarily mean that periodontitis does not contribute to the total burden of inflammation as there was a tendency for hs-CRP to decrease following successful periodontal treatment. Large-scale studies are clearly needed to determine the impact of periodontal disease on systemic inflammation.
