Clinical and microbiological effect of scaling and root planing in smoker and non-smoker chronic and aggressive periodontitis patients

OBJECTIVES: To compare the effects of scaling and root planing (SRP) on clinical and microbiological parameters at selected sites in smoker and non-smoker chronic and generalized aggressive periodontitis patients. MATERIALS AND METHODS: Clinical parameters including probing depth (PD), relative attachment level (RAL), and bleeding upon probing (BOP), and subgingival plaque samples were taken from four sites in 28 chronic periodontitis (CP) and 17 generalized aggressive periodontitis (GAgP) patients before and after SRP. Polymerase chain reaction assays were used to determine the presence of A. actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythensis, Prevotella intermedia and Treponema denticola. RESULTS: Both CP and GAgP non-smokers had significantly greater reduction in pocket depth (1.0+/-1.3 mm in CP smokers versus 1.7+/-1.4 mm in non-smokers, p=0.007 and 1.3+/-1.0 in GAgP smokers versus 2.4+/-1.2 mm in GAgP non-smokers, p<0.001) than respective non-smokers, with a significant decrease in Tannerella forsythensis in CP sites (smokers 25% increase and non-smokers 36.3% decrease, p<0.001) and Prevotella intermedia at GAgP sites (smokers 25% reduction versus 46.9% in non-smokers, p=0.028). CONCLUSION: SRP was effective in reducing clinical parameters in both groups. The inferior improvement in PD following therapy for smokers may reflect the systemic effects of smoking on the host response and the healing process. The lesser reduction in microflora and greater post-therapy prevalence of organisms may reflect the deeper pockets seen in smokers and poorer clearance of the organisms. These detrimental consequences for smokers appear consistent in both aggressive and CP.     

GCF MMP-8 levels in smokers and non-smokers with chronic periodontitis following scaling and root planing accompanied by systemic use of flurbiprofen

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.     

Mechanical therapy with adjunctive minocycline microspheres reduces red-complex bacteria in smokers

BACKGROUND: Smoking increases the risk for periodontal disease and reduces the healing response. We examined the antimicrobial and clinical effects of scaling and root planing (SRP) with and without minocycline HCl 1 mg microspheres (MM) relative to smoking status in subjects with periodontitis. METHODS: A total of 127 subjects (46 never smokers, 44 former smokers, and 37 current smokers) with moderate to advanced periodontitis were randomized to receive MM + SRP (N = 62) or SRP alone (N = 65). Subgingival plaque samples collected at baseline and day 30 were examined for the presence of 40 periodontal bacteria by DNA probe analysis. RESULTS: MM + SRP reduced red-complex bacteria (RCB) numbers and proportions to a greater extent than SRP alone, irrespective of smoking status. RCB numbers were not reduced by SRP in current smokers. The difference in the reduction in numbers of RCB by SRP relative to MM + SRP in current smokers was statistically significant (P <0.05). Numbers and proportions of orange complex bacteria (OCB) were reduced in all groups treated with MM + SRP. Proportions of OCB increased in current smokers treated with SRP alone. In current smokers, MM + SRP significantly reduced probing depth (PD), increased clinical attachment level (CAL), and reduced bleeding on probing (BOP) to a greater extent than SRP alone (P <0.05). CONCLUSIONS: SRP alone was ineffective at reducing numbers or proportions of RCB or OCB in current smokers, whereas MM + SRP significantly reduced both. MM + SRP also improved PD, BOP, and CAL to a greater extent than SRP alone independent of smoking status.     

Non-surgical periodontal treatment with and without adjunctive metronidazole in smokers and non-smokers

AIM: To determine whether adjunctive metronidazole therapy would compensate for the poorer treatment response to scaling and root planing reported in smokers. METHOD: A single-blind, randomised clinical trial of 28 smokers and 56 non-smokers, stratified for periodontitis disease severity and randomly allocated to 3 treatment groups: (1) Scaling and root planing using an ultrasonic scaler with local anaesthesia (SRP), (2) SRP+ metronidazole tabs 200 mg tds for 7 days, (3) SRP + 2 subgingival applications of 25% metronidazole gel. Probing depths (PD) and attachment levels (AL) were recorded with a Florida probe at baseline, 2 months and 6 months post treatment by a single examiner who was unaware of the treatment modality. Results were analysed for all sites with baseline probing depths equal to or greater than Florida probe recordings of 4.6 mm using analysis of variance. RESULTS: Reductions in probing depth at 6 months were significantly less (p < 0.001) in the smokers (mean 1.23 mm, 95% confidence intervals = 1.05 to 1.40 mm) than in the non-smokers (1.92, 1.75 to 2.09 mm). Attachment level gains were approximately 0.55 mm and there was no statistically significant difference between smokers and non-smokers. There were no differences in any clinical measure in response to the three treatment regimens at 2 or 6 months for either smokers or non-smokers. A reduction in the proportion of spirochaetes was observed at 6 months which was less in smokers than in non-smokers (p = 0.034). Multiple linear regression analysis on probing depth at 6 months demonstrated that smoking was a significant explanatory factor (p < 0.001) for poor treatment outcome, whilst the presence or absence of adjunctive metronidazole was not (p = 0.620). CONCLUSION: This study confirms that smokers have a poorer treatment response to SRP, regardless of the application of either systemic or locally applied adjunctive metronidazole.     

Adjunctive subantimicrobial dose doxycycline in smokers and non-smokers with chronic periodontitis

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.     

The effects of subgingival calculus on the clinical outcomes of locally-delivered controlled-release doxycycline compared to scaling and root planing

BACKGROUND, AIM: The effect of subgingival calculus on the clinical outcomes of the local delivery of antimicrobials is unknown. This study examines the clinical outcomes of treatment with locally delivered controlled-release doxycycline (DH) or scaling and root planing (SRP) in subsets of adult periodontitis patients with known baseline levels of subgingival calculus. METHODS: The data examined were obtained from 393 patients who participated in 2 multi-center trials. All patients had baseline subgingival calculus levels assessed and were then treated at baseline and month 4 with either DH or SRP. Clinical attachment levels (CAL), pocket depth (PD) and bleeding on probing (BOP) were assessed at baseline and months 1, 2, 4, 5, 6, 8 and 9. RESULTS: Treatment with either DH or SRP resulted in significant statistical and clinical improvements in CAL, PD and BOP. These clinical outcomes were equivalent regardless of the extent of subgingival calculus present at baseline. CONCLUSIONS: The results indicate that the primary clinical effects of these therapies are the result of a disruption and reduction of the subgingival plaque and not the effect of the removal of subgingival calculus and contaminated cementum.     

一次性全口龈下刮治和根面平整术治疗慢性牙周炎的近期疗效评价

目的：探讨一次性全口龈下刮治和根面平整术（full-mouth scaling and root planning，FM-SRP）治疗慢性牙周炎的效果，并与常规的分象限刮治（quadrant scaling and root planning，Q-SRP）效果进行比较。方法：将60例慢性牙周炎患者随机分为2组：FM-SRP组在1天内完成全口所有象限的刮治和根面平整。而Q-SRP组每周进行1个象限的刮治，连续4周完成全口治疗。分别在基线、3个月和6个月时，检测菌斑指数（plaque index，PI）、牙龈指数（gingival index，GI）、探诊出血（bleeding on probing，BOP）、探诊深度（probing depth。PD）及附着丧失（attachment loss，AL）的变化及患者的术后反应。所得结果分别进行秩和检验（PI、GI）、t检验（PD、AL）和X^2检验（BOP）。结果：与基线时相比，2种治疗方式在3个月和6个月时的所有临床牙周指数均有显著改善（P〈0．01），但2组之间无显著性差异（P〉0．05）。在首次治疗24h，FM-SRP组的术后反应发生率显著高于Q-SRP组（P〈0.05），但患者能够耐受。结论：FM-SRP和Q-SRP两种方法均可达到相同的临床效果，临床医生可根据实际需要，选择合适的治疗方式。     

牙龈卟啉单胞菌与牙周基础治疗关系的实验研究

目的应用TaqMan实时荧光定量聚合酶链反应法检测慢性牙周炎患者牙周洁刮治术（SRP）治疗前后龈下菌斑中牙龈卟啉单胞菌（P. gingivalis）的变化,分析P. gingivalis与SRP疗效之间的关系,探讨应用实时荧光定量聚合酶链反应监测和评价SRP的可能性。方法选择20例中重度慢性牙周炎患者为研究对象,检查SRP治疗前后的临床指标,包括探诊深度（PD）、临床附着丧失（CAL）和探诊出血（BOP）;采集SRP治疗前后的龈下菌斑共142个样本,应用TaqMan实时荧光定量聚合酶链反应检测样本中的P. gingivalis。构建含有P. gingivalis扩增片段的重组质粒,建立定量标准。结果慢性牙周炎患者SRP治疗后PD、CAL和BOP均明显下降（P<0.001）;治疗前P. gingivalis检出率为80.28%,治疗后下降为54.23%;治疗前P. gingivalis数量与PD相关,Kendall相关系数为0.70（P<0.001）,治疗后牙周袋内细菌数量明显减少（P<0.001）。治疗前牙周袋内P. gingivalis的定植数量与PD、CAL和BOP的改善无相关性（P>0.05）,但治疗后治疗有效位点P. gingivalis数量减少程度明显大于治疗无效位点（P<0.05）,细菌减少量与PD改善弱相关（r=0.25,P=0.04）。结论SRP治疗可以明显改善临床症状,降低P. gingivalis检出率和绝对数量;治疗前P. gingivalis定植水平对临床指标的改善没有影响,治疗后P. gingivalis数量下降程度可以反映治疗效果。TaqMan实时荧光定量聚合酶链反应可以用于牙周炎治疗效果的监测和评价。
