AIM: The main purpose of this study was to investigate the effect of smoking on the serum levels of folic acid and vitamin B(12) in smokers and nonsmokers with chronic periodontal disease after nonsurgical intervention. MATERIAL AND METHODS: The study base consisted of 45 current smokers and 43 nonsmokers. The clinical parameters included plaque index (PI), gingival index (GI), pocket depth (PD), and clinical attachment level (CAL). Folic acid and vitamin B(12) were determined from peripheral blood samples. Clinical measurements and blood samples were collected at baseline and 1, 3, and 6 months after the intervention. RESULTS: Mean PI was significantly greater in smokers compared with non-smokers throughout the observation period (p<0.001). During the first month, GI levels significantly decreased in both groups. From months 1 through 6, a significant return towards an increased GI level was observed in smokers (p<0.001). PD and CAL levels significantly decreased during the first month in both groups. Thereafter, increasing levels of PD and CAL were seen in both groups, although significantly more pronounced in smokers. Throughout the observation period, the mean CAL was significantly greater in smokers relative to nonsmokers (p<0.001). In smokers, the mean folic acid level gradually and significantly decreased and a slight and significant decrease in mean vitamin B(12) levels was observed in both groups over the entire observation period (p<0.001). CONCLUSION: The clinical response to nonsurgical intervention is impaired by smoking and smoking seems to negatively influence the serum level of folic acid following non-surgical intervention.  相似文献

OBJECTIVE: Smoking is an important environmental risk factor for the initiation and progression of periodontal diseases. The aim of this study was to evaluate the effects of smoking on clinical parameters and the gingival crevicular fluid (GCF) contents of the pro-inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) levels in patients with chronic periodontitis. MATERIAL AND METHODS: The study base consisted of 41 patients including 22 volunteer current smokers with an age range of 32-59 (44.41+/-7.88) years and 19 volunteer non-smokers with an age range of 36-59 (46.94+/-6.07) years. The first month after non-surgical periodontal therapy was accepted as the baseline of the study. The clinical parameters including plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL) were recorded and GCF samples were collected for analysis of GCF contents of IL-6 and TNF-alpha levels. At the 3rd and 6th months, all of these procedures were repeated. RESULTS: In smokers, only CAL was significantly higher at the 3rd month compared with non-smokers (p<0.05). GI and BOP were higher in non-smokers than smokers in both periods (p<0.05). PI showed increases from the initial to the 6th month in smokers (p<0.05). Although the differences between two groups with regard to IL-6 and TNF-alpha were not significant (p>0.05), the total amount of TNF-alpha in GCF decreased from the initial to the 6th month in smokers (p<0.05). There were no significant correlations between the mean total amount of IL-6 and TNF-alpha in GCF and clinical parameters in both evaluation periods in smokers (p>0.05). CONCLUSION: The present study demonstrated that cigarette smoking increases the amount of dental plaque over time in smokers and does not influence GCF contents of IL-6 and TNF-alpha.  相似文献

IntroductionPeriodontal disease is a chronic inflammatory condition of the periodontium. It is the main cause of tooth loss and is considered one of the biggest threats to the oral cavity. Tobacco smoking has long been associated with increased risk for periodontal, peri-implant, and other medical diseases.ObjectiveTo evaluate the effect of smoking and its level on periodontal clinical parameters (probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), bleeding on probing (BOP), and the volume of gingival crevicular fluid (GCF)) in healthy and chronic periodontitis individuals.Material and MethodA total of 160 participants were recruited in the present study, who were equally divided into the following five groups: healthy controls (C), healthy smokers (HS), nonsmokers with periodontitis (PNS), light smokers with periodontitis (PLS), and heavy smokers with periodontitis (PHS). GCF volume and periodontal clinical parameters (PD, PI, GI, CAL, and BOP) were assessed for each participant and compared between the study groups.ResultThere was a statistically significant difference in PD, PI, GI, CAL, and BOP between healthy and periodontitis patients (p < 0.001). The mean PI, PD, and CAL were considerably higher in heavy smokers than light smokers and non-smokers (P < 0.001). In contrast, the mean GI and BOP were significantly lower in heavy smokers than in light smokers and non-smokers. There was a statistically significant difference in GCF between healthy and periodontitis patients (p < 0.001). The mean GCF readings were higher in heavy smokers than light smokers or non-smokers (P < 0.001).ConclusionThe present study confirms the influence of smoking on periodontal clinical parameters. Smoking was associated with increased PD, PI, CAL, and GCF readings; however, GI and BOP were decreased in smokers. The number of cigarettes played a key role in the volume of GCF and periodontal clinical parameters.  相似文献

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine''s vasoconstrictor effect.  相似文献

BACKGROUND: Cigarette smoking is accepted as an important factor that increases the risk for the initiation and progress of chronic periodontitis. However, the effect of cigarette smoking on the recurrence of disease in patients undergoing regular maintenance therapy is less understood. Therefore, we set out to assess disease progression longitudinally in smoking and non-smoking subjects with chronic periodontitis undergoing periodontal maintenance therapy every 3 to 4 months. METHODS: A total of 108 subjects undergoing regular maintenance therapy for chronic periodontitis were followed over a 3-year period. Self-reports of smoking status were confirmed by analysis of exhaled carbon monoxide concentrations. Clinical parameters (plaque index [PI], bleeding on probing [BOP], clinical attachment loss [CAL], probing depth [PD], and tooth loss) were recorded at yearly reevaluation visits. The study was carried out in a university hospital setting. RESULTS: Longitudinal measurements were obtained from 81 (75%) subjects. There were no differences in inflammatory indices at baseline or over time (PI and BOP; both P >0.05) between smokers (N = 16; age: 54 +/- 6 years) and non-smokers (N = 65; age: 59 +/- 14 years). Likewise, there was no difference between the smoking groups with respect to disease progression (measured as changes in prevalence [number] and proportion [percentage] of progressing sites and as mean CAL, PD, and tooth loss; all P >0.05). CONCLUSION: In this small population, regular maintenance treatment in a cross-section of highly motivated subjects with chronic periodontitis seemed to be equally successful in preventing progressive periodontal tissue destruction in current smokers and current non-smokers.  相似文献

BACKGROUND: Cigarette smoking has been identified as an important risk factor for the initiation and progression of chronic periodontitis (CP). The aim of this study was to investigate the effects of phase I periodontal therapy and adjunctive flurbiprofen administration on matrix metalloproteinase (MMP)-8 levels in gingival crevicular fluid (GCF) samples from smoking and non-smoking patients with CP. METHODS: Twenty-nine non-smoking and 29 smoking patients with CP were divided into four groups according to periodontal treatment modalities. Group 1 (non-smokers with CP) and group 3 (smokers with CP) patients received daily 100-mg flurbiprofen tablets in a 2 x 1 regimen for 10 days together with scaling and root planing (SRP). Patients in group 2 (non-smokers with CP) and group 4 (smokers with CP) received placebo tablets in a 2 x 1 regimen for 10 days together with SRP. Plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment level (CAL) measurements were recorded; GCF samples were collected from each sampling area at baseline and after the 10-day period of drug intake by a single examiner who was unaware of the treatment modality. Assays for GCF MMP-8 were carried out by an enzyme-linked immunosorbent assay. RESULTS: All groups showed statistically significant reductions in PI and GI scores following the phase I periodontal treatment (P < 0.05), but no statistical differences were observed in PD and CAL scores after therapy. In all groups, the reduction of GCF MMP-8 levels after therapy was statistically significant compared to baseline levels (P < 0.001). When groups 1 and 3 and 2 and 4 were compared according to GCF MMP-8 levels after the therapy, no statistically significant differences were observed (P = 0.117 and P = 0.485, respectively). CONCLUSION: Flurbiprofen administration had no additional inhibitory effect over SRP alone on GCF levels of MMP-8 in smokers compared to non-smokers with CP.  相似文献

OBJECTIVES: Previous studies have demonstrated the clinical benefits of sub-antimicrobial dose doxycycline (SDD) in the treatment of chronic periodontitis (CP). The aim of this study was to retrospectively evaluate the role of SDD as an adjunct to scaling and root planing (SRP) in the treatment of smokers and non-smokers with CP. MATERIAL AND METHODS: A meta-analysis of two previously reported clinical studies was undertaken. Both were 9-month, double-blind, randomized, placebo-controlled, multi-centre clinical trials that investigated the efficacy of SDD (20 mg doxycycline twice daily) in combination with SRP in subjects with moderate-severe CP. 36.9% of the combined study population were smokers. Three hundred and ninety-two subjects were included in the meta-analysis, which evaluated per-subject mean changes in clinical attachment level (CAL) and probing depth (PD) from baseline and the total number of sites with attachment gains and PD reductions > or =2 and > or =3 mm from baseline in four subgroups: smokers/SDD; smokers/placebo; non-smokers/SDD; non-smokers/placebo. RESULTS: A hierarchical treatment response was observed, with non-smokers who received SDD demonstrating the greatest CAL gains and PD reductions. Smokers who received placebo demonstrated the smallest clinical improvements following treatment. Smokers who received SDD demonstrated an intermediate treatment response that was broadly equivalent to that seen in non-smokers who received placebo. In sites with baseline PD 4-6 mm, month 9 CAL gains were 19-45% better in non-smokers who received SDD compared with all other subgroups (p<0.05), and were 21% greater in smokers who received SDD compared with smokers who received placebo (p<0.05). Furthermore, month 9 PD reductions were 21-53% greater in non-smokers who received SDD compared with all other subgroups (p<0.01), and were 26% greater in smokers who received SDD compared with smokers who received placebo (p<0.05). CONCLUSION: Adjunctive SDD enhances therapeutic outcomes compared with SRP alone, resulting in clinical benefit in both smokers and non-smokers with CP.  相似文献

Effect of cigarette smoking on periodontal status of healthy young adults   总被引:6,自引:0,他引:6  
BACKGROUND: It has been shown that tobacco is a significant risk factor for periodontal disease; however, there have been few studies on young populations where problems of general health can be discounted. The purpose of this study was to examine the influence of tobacco consumption on the periodontal condition of a young, healthy population. METHODS: The study population consisted of 304 young Caucasian males (average age 19.38 +/- 0.72 years) entering the Armed Forces. All the subjects completed a self-administered questionnaire on age, oral hygiene habits, previous dental examinations, and quantity and length of tobacco use. The periodontal examination consisted of the plaque index (PI); periodontal bleeding index (PBI); probing depth (PD); and clinical attachment level (CAL). One- and 2-way ANOVA was used to compare data recorded between smokers and non-smokers. RESULTS: Forty-six percent of subjects reported that they brushed their teeth at least once a day, but only 13% visited a dentist at least once a year. Over half (53%) were habitual smokers, 43% smoking between 5 and 20 cigarettes per day; 39% of the smokers had been smoking for less than 5 years. Mean PI was 31.24 +/- 14.88 (27.19 +/- 15.93 for smokers and 35.78 +/- 12.17 for non-smokers), with significant differences between non-smokers and those who smoked 5 to 20 cigarettes per day (26.85 +/- 16.11, P<0.0001). Mean PBI was 42.29 +/- 8.43 (non-smokers 44.67 +/- 6.53 and smokers 40.17 +/- 9.46). Significant differences were found between the PBI of the non-smokers and of those who smoked 5 to 20 cigarettes per day (39.90 +/- 9.64, P <0.0001). There were also differences in the PBI between those who brushed their teeth once (40.53 +/- 9.61) and twice (44.86 +/- 5.9) a day (P<0.0001). Mean PD was 1.62 +/- 0.43 mm (non-smokers 1.56 +/- 0.36 and smokers 1.68 +/- 0.49). Deeper probing depths were recorded among smokers than among non-smokers, with statistically significant differences (P<0.049); statistically significant differences were also found between those who attended (1.49 +/- 0.50) and those who did not attend (1.65 +/- 0.42) regular dental check-ups (P<0.031). Mean CAL 1.75 +/- 0.41 (non-smokers 1.64 +/- 0.32 and smokers 1.82 +/- 0.44). CONCLUSIONS: It may be concluded that, even at such an early age, tobacco consumption affects the periodontal health. It is necessary to inform young smokers of the risk of tobacco use regarding periodontal health.  相似文献

OBJECTIVE: Previous studies demonstrate a relationship between a lack of vitamin C and increased risk of periodontal disease. In the present study we examine the vitamin C plasma levels and inflammatory measures in periodontitis patients before and after the consumption of grapefruit. SUBJECTS AND METHODS: Fifty-eight patients with chronic periodontitis were assigned to the test group (non-smokers n=21, smokers n=17) and a diseased control group (non-smokers n=11, smokers n=9). Furthermore, 22 healthy subjects were recruited to compare vitamin C plasma levels between periodontally diseased and healthy subjects. Clinical evaluations, including plaque index (PI), sulcus bleeding index (SBI), probing pocket depths (PPD) and plasma vitamin C levels, were performed at baseline, and after two weeks of grapefruit consumption. RESULTS: At baseline, we observed significantly reduced plasma vitamin C levels in the test group and diseased controls in comparison with the healthy controls. On principle, smokers showed lower levels of vitamin C (mean 0.39 +/- 0.17 mg dl(-1)) than non-smokers (mean 0.56+/-0.29 mg dl(-1)). After grapefruit consumption, the mean plasma vitamin C levels rose significantly in the test group compared to the diseased controls (non-smokers: 0.87+/-0.39 mg dl(-1), smokers: 0.74+/-0.30 mg dl(-1)). Furthermore the SBI was reduced in the test group (non-smokers: from 1.68+/-0.6 to 1.05+/-0.6, p<0.001), whereas PI and PPD were unaffected. CONCLUSION: The present results show that periodontitis patients are characterised by plasma vitamin C levels below the normal range, especially in smokers. The intake of grapefruit leads to an increase in plasma vitamin C levels and improves sulcus bleeding scores. Longer term studies are necessary to determine whether other periodontal outcomes improve with such supplementation especially in smokers.  相似文献

Background: Several studies have shown a possible association between periodontal disease and obesity. The aim of this study is to evaluate serum plasminogen activator inhibitor 1 (PAI‐1), tumor necrosis factor‐alpha (TNF‐α), and high‐sensitivity C‐reactive protein (hsCRP) levels in the association between obesity and periodontal disease. Methods: Two hundred individuals participated in this study. Body mass index (BMI), waist‐to‐hip ratio, plasma triglyceride (TRG), total cholesterol, low‐density lipoprotein cholesterol, high‐density lipoprotein cholesterol (HDL‐C), fasting blood glucose (FBG), hsCRP, TNF‐α, PAI‐1, and periodontal parameters (including plaque index [PI], probing depth [PD], clinical attachment level [CAL], and percentage of sites with bleeding on probing) were evaluated. Results: The groups with BMI ≥ 25 had higher median values for FBG, TRG, hsCRP, PAI‐1, PI, and CAL than did the groups with a BMI < 25 (P <0.01). Serum TRG levels were positively correlated with PI, PD, and CAL. There were negative associations between clinical periodontal parameters and HDL‐C. There were statistically significant correlations between PAI‐1 and clinical periodontal parameters (PI, PD, and CAL). Conclusion: Serum PAI‐1 levels may play an important role in the association between periodontal disease and obesity.  相似文献

BACKGROUND: The purpose of the present parallel design, controlled clinical trial was to evaluate the treatment outcome following flap debridement surgery (FDS) in cigarette smokers compared to non-smokers. METHODS: After initial therapy, 57 systemically healthy subjects with moderate to advanced periodontitis who presented with one area (at least 3 teeth) where surgery was required were selected. Twenty-eight patients (mean age: 39.6 years, 20 males) were smokers (> or = 10 cigarettes/day); 29 patients (mean age: 43.9 years, 7 males) were non-smokers. Full-mouth plaque (FMP) and bleeding on probing (BOP) scores, probing depth (PD), clinical attachment level (CAL), and recession depth (RD) were assessed immediately before and 6 months following surgery. Only sites with presurgery PD > or = 4 mm were used for statistical analysis. RESULTS: Presurgery FMP and BOP were similar in smokers and non-smokers and significantly decreased postsurgery in both groups. Overall, PD reduction and CAL gain were greater, although not significantly, in non-smokers (2.4 +/- 0.9 mm and 1.6 +/- 0.7 mm, respectively) than in smokers (1.9 +/- 0.7 mm and 1.2 +/- 0.7 mm, respectively). For moderate sites (PD 4 to 6 mm), no significant differences in PD and CAL changes were found between groups. For deep sites (PD > or = 7 mm), PD reduction was 3.0 +/- 1.0 mm in smokers and 4.0 +/- 0.8 mm in non-smokers, and CAL gain amounted to 1.8 +/- 1.1 mm in smokers and 2.8 +/- 1.0 mm in non-smokers (P = 0.0477). In smokers, 16% of deep sites healed to postsurgery PD values < or = 3 mm as compared to 47% in non-smokers (P = 0.0000); 58% of deep sites in smokers showed a CAL gain > or = 2 mm, as compared to 82% in non-smokers (P = 0.0000). CONCLUSIONS: Results of the study indicated that: 1) FDS determined a statistically significant PD reduction and CAL gain in patients with moderate to advanced periodontitis; 2) smokers exhibited a trend towards less favorable healing response following FDS compared to non-smokers, both in terms of PD reduction and CAL gain; and 3) this trend reached clinical and statistical significance at sites with initial deep PD.  相似文献

BACKGROUND: The periodontal status of 41 medically healthy adults with untreated chronic periodontitis was monitored before and after scaling and root planing (SRP). METHODS: During a 6-month pretreatment phase, clinical measurements, digital subtraction radiography (DSR) analysis of alveolar bone, and measurement of gingival crevicular fluid (GCF) prostaglandin E2 (PGE2) levels were undertaken. SRP was provided during a 1-month treatment phase. Clinical, radiographic, and biochemical analyses were repeated in a 6-month post-treatment healing period. RESULTS: Pretreatment: no clinically significant changes in mean plaque indices (PI), probing depths (PD), bleeding on probing (BOP), or relative clinical attachment levels (CAL) were detected (P>0.05). DSR revealed small but statistically significant bone height (0.04 mm) and mass (0.97 mg) loss (P<0.001). GCF PGE2 levels gradually increased from 38.8 ng/ml at month 1 to 79.4 ng/ml at month 6. Post-treatment: statistically and clinically significant reductions were observed in mean PI, BOP, and PD (P<0.05). A statistically significant reduction in CAL was noted (P<0.05). The trend towards progressive bone loss was halted and reversed, and a statistically significant decrease in GCF PGE2 concentrations was detected (P<0.001). Smokers, non-smokers, and ex-smokers did not differ significantly in PI, BOP, CAL, radiographic, or biochemical parameters at any time. Mean PD was significantly greater in current smokers than in non- and ex-smokers (P<0.005). PD reduced comparably in all 3 smoking subgroups following treatment (P<0.01). CONCLUSIONS: Conventional clinical measurements failed to identify disease progression over a 6-month period. Significant improvements were observed in clinical parameters after SRP, and a trend towards progressive bone loss was halted and reversed. Regular and frequent maintenance visits are important following treatment to maintain improvements in clinical parameters. Smokers had deeper probing depths than non- and ex-smokers, but pockets were reduced significantly and comparably in all 3 smoking subgroups following efficacious treatment.  相似文献

BACKGROUND: It has been established that smoking is an important risk factor for the initiation and progression of chronic periodontitis (CP). This study investigates the effects of phase I periodontal therapy and adjunctive flurbiprofen administration on prostaglandin E(2) (PGE(2)) and thiobarbituric acid reactive substance (TBARS) levels in gingival crevicular fluid (GCF) samples from smoker and non-smoker patients with CP. METHODS: Twenty-one non-smoker and 21 smoker patients with CP were divided into four groups according to treatment modalities. Group 1 (non-smokers with CP) and group 3 (smokers with CP) patients received daily 100-mg flurbiprofen tablets in a 2 x 1 regimen for 10 days together with scaling and root planing (SRP). Patients in group 2 (non-smokers with CP) and group 4 (smokers with CP) received placebo tablets in a 2 x 1 regimen for 10 days together with SRP. Plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment level (CAL) measurements were recorded and GCF samples were collected at baseline and on day 10 of drug intake from each sampling area by a single examiner who was unaware of the treatment modality. Assays for GCF PGE(2) and TBARS were carried out by an enzyme-linked immunosorbent assay and fluorometric method, respectively. RESULTS: All groups showed statistically significant reductions in PI and GI scores following the phase I periodontal treatment on day 10 (P <0.05), but no statistical differences were observed in PD and CAL scores after the therapy. In groups 1 and 2, the reduction of GCF PGE(2) and TBARS levels were not significant after the therapy compared to baseline levels. In group 3, GCF PGE(2) and TBARS levels exhibited a statistically significant decrease (P <0.05) after the therapy. Group 4 showed significant reductions (P <0.05) in GCF PGE(2) levels after the therapy. No statistically significant reductions were observed in group 4 with regard to GCF TBARS levels. When groups 1 and 3 were compared according to GCF TBARS levels after the therapy, a more statistically significant reduction was observed in group 3 (P = 0.001). CONCLUSION: These results suggest that additional flurbiprofen administration may have more inhibitory effects on GCF levels of PGE(2) and TBARS in the groups of smokers compared to non-smokers with CP.  相似文献

BACKGROUND: The aim of the present study was to evaluate gingival crevicular fluid (GCF) leptin levels and the influence of long-term and heavy smoking on GCF leptin levels in patients with chronic periodontitis. METHODS: In this study, 143 individuals were divided into three groups: non-smokers (NS), smokers (S), and control (C). Three subgroups of NS and S were grouped as follows: a) probing depth (PD) 5 mm. For each patient, PD, gingival index (GI), plaque index (PI), gingival bleeding time index (GBTI), and clinical attachment level (CAL) values were recorded. The GCF leptin levels obtained from sampling sites were determined by using enzyme-linked immunosorbent assay kits. RESULTS: The GCF leptin levels were found significantly lower in the a and b subgroups in the S group than those in the NS group (P <0.05). The inflammatory markers GI and GBTI showed significant correlations with leptin in NS (P <0.05). CONCLUSIONS: Our results suggest that higher leptin GCF levels in healthy sites in periodontitis patients may play a protective role in periodontal disease. Further studies are needed to determine the cellular origin of the leptin in the gingiva and the effect of plasma leptin levels on GCF leptin concentrations.  相似文献

BACKGROUND: The purpose of this clinical study was to evaluate the possible influence of testosterone hormone on common clinical measurements of periodontal disease in men with hypergonadotropic hypogonadism. METHODS: Twenty-four hypergonadotropic hypogonadal men (H) and 24 systemically healthy men (S) were divided into two groups as chronic periodontitis and clinically healthy controls after clinical examinations and radiographs. The H group consisted of 12 control (H/C) and 12 chronic periodontitis (H/P) patients, and the S group consisted of 12 control (S/C) and 12 chronic periodontitis (S/P) patients. Plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment loss (CAL) scores were recorded. RESULTS: The mean of all clinical parameters (PI, GI, BOP, PD, and CAL) were significantly (P<0.05) higher in periodontitis groups (H/P and S/P) than controls (H/C and S/C). There were no significant differences in the PD and CAL scores between periodontitis groups (S/P and H/P). The mean of GI and BOP scores were statistically higher in the H/P group than the S/P group (P<0.05). There was a negative correlation between GI and free testosterone levels (r=-0.794; P<0.05). CONCLUSION: According to these results, serum testosterone levels may possibly influence periodontal disease in men, and testosterone may have an inhibitory effect on gingival inflammation.  相似文献

BACKGROUND: Diabetes is a major risk factor for the development of periodontal disease in certain populations. The prevalence of type 2 diabetes is increased in Hispanic Americans, but its impact on the extent and severity of periodontal disease in this population has not been determined. METHODS: Sixty-three Hispanic Americans, aged 33 to 72 years, from South Texas were grouped based on the presence or absence of type 2 diabetes. Past medical histories, including smoking, were obtained. Periodontal status was evaluated by measuring probing depth (PD), clinical attachment level (CAL), plaque, bleeding on probing, visual gingival inflammation, and calculus. RESULTS: Type 2 diabetes was associated frequently with major medical complications in this population. Diabetes was associated with significantly more calculus formation and tooth loss and an increased extent and severity of periodontitis. Subjects with diabetes had nearly three times the mean CAL and frequency of PD >6 mm than subjects without diabetes and nearly twice the frequency of moderate to advanced attachment loss (> or =3 mm). Smoking and diabetes had significant independent effects on mean CAL and the frequency of deep pockets. Diabetes and smoking combined were associated with a significantly higher frequency of sites with CAL > or =3 mm compared to healthy non-smokers, healthy smokers, and non-smokers with diabetes. CONCLUSIONS: Hispanic Americans with type 2 diabetes had more supra- and subgingival calculus, an increased extent and severity of periodontal destruction, and an increased frequency of tooth loss due to periodontitis. An additive/synergistic contribution of type 2 diabetes and smoking for increasing the extent of periodontal disease was observed.  相似文献

Objectives: There is evidence about a possible relationship existing between periodontal diseases and coronary heart disease. The aim of the present longitudinal study was to investigate the changes in periodontal evolution after etiological periodontal treatment, comparing a healthy control group with another having coronary heart disease. Study Design: The study included initially 55 patients of which 44 finished it. They were placed into two groups: Healthy Control Group (HCG) n =9, and Coronary Heart Disease Group (CHDG) n=35. The gingival level (GL), probing depth (PD), clinical attachment level (CAL), plaque index (PI) and bleeding on probing (BOP) were measured to compare the periodontal status in both groups. The patients were examined and etiological periodontal treatment was performed and they were then examined at the end of 1 and 10 years. Statistical method: A one way-ANOVA and a MR-ANOVA were established; significance p<0.05. Results: No significant differences between both groups were detected on the first visit (p>0.5). However, at the second visit the CHDG presented a significantly higher PD (p<0.05) and PI (p<0.01). CHDG patients gradually increase PD through time and in comparison to the control group (p<0.041). CHDG patients present a significantly higher CAL loss (p<0.0385) and a significant increase in PI (p<0.0041) at the end of one year, while on the third visit no significant differences were detected in any of these indices. Likewise, a similar fact can be observed on evaluating BOP at the end of ten years causal treatment, a smaller decrease in the cardiac group was observed in regards to the initial values (p<0.001). Conclusion: Patients with coronary heart disease showed a worse evolution of periodontal indices than healthy ones, when referring to probing depth, plaque index and bleeding on probing index. Key words:Attachment loss, coronary heart disease, periodontal disease, risk factors.  相似文献

BACKGROUND: The aim of this study was to evaluate the clinical outcome in patients with recurrent periodontal disease following treatment with 25% metronidazole gel. METHODS: Twenty subjects in a maintenance care program but with recurrent periodontal disease participated. Three months after scaling and root planing, a total of 40 sites, 2 in each patient, with probing depth > or = 5 mm were selected. One site randomly selected was treated with metronidazole gel (test) and the other site with a placebo gel (control). Baseline and follow-up measurements included plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL). RESULTS: There were no statistically significant differences in PI, GI, BOP, PD, or CAL between test and control sites. CONCLUSION: This study showed that local treatment with 25% metronidazole gel did not seem to influence the clinical healing in this group of subjects with recurrent periodontal disease.  相似文献

Oral Diseases (2011) 17 , 515–521 Objective: The present study evaluated the relationship between periodontal disease and its clinical variables in Brazilian non‐diabetic pregnant women (C), gestational diabetes mellitus (GDM), or type 1 diabetes mellitus (T1DM). Subjects and methods: A periodontal exam was performed in one hundred and sixty‐one pregnant women (GDM:80; T1DM:31; C:50) by a single‐blinded calibrated examiner who recorded plaque index (PI), gingival index (GI), bleeding index (BI), gingival margin location (GM), probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and tooth mobility index (MI). The medical variables were age, pregestational body mass index (pre‐BMI), fasting plasma glucose (FPG), and glycated hemoglobin (HbA 1c ). Results: The GI, GM, PD, CAL, BOP, and MI were significantly higher ( P < 0.01) among GDM and T1DM than for C. The PI was higher in GDM and similar between C and T1DM. The Adjusted Final Model for medical variables to evaluate the effects of groups on periodontal parameters confirmed these results. Conclusions: The presence of periodontal disease was significantly higher in Brazilian diabetic pregnancies (GDM and T1DM) when compared to non‐diabetic pregnant women (C). The degree of periodontal disease was similar between the GDM and T1DM groups. Age, pregestational BMI, and HbA1c were factors related to CAL development in these two types of diabetes mellitus.  相似文献
