Abstract
AIMS To evaluate the therapeutic efficacy of azithromycin (azm) and/or metronidazole (mtz) on the histopathological features of rats' gingival overgrowth (GO) induced by cyclosporine-A (CsA) in an animal model. METHODS Ninety male albino rats were divided randomly into six equal groups. The rats of group I received corn oil via gastric feeding for 7 weeks. Group II rats were administered CsA for the same period. Groups III, IV, and V rats received CsA for 6 weeks and simultaneously in the 7th week received a monotherapy of placebo gel, azm suspension, mtz gel, respectively. Group VI rats were handled as groups III, IV, and V and instead received a combined therapy of azm suspension, and mtz gel. Rats were euthanized at the end of the experiment and routine tissue processing was carried out. The obtained specimens were stained with H&E, TGF-β, MMP-1, and IL-6 antibodies. RESULTS One-way MANOVA test for TGF-β, MMP-1, and IL-6 revealed an overall significant difference between the different groups (P = 0.000). LSD post hoc test for multiple comparisons of TGF-β revealed nonsignificant difference between groups I and VI and between groups IV and V. Nonsignificant difference was found between groups II and III considering the amount of MMP-1 immune expression. In addition, nonsignificant difference was found between groups V and VI regarding the amount of immune expression for IL-6. CONCLUSION Combined therapy of azm suspension and mtz gel significantly improved the histopathological features of CsA-induced GO better than a monotherapy of azm suspension or mtz gel.

Abstract
BACKGROUND Meta-analysis was used to assess the effectiveness of local delivery of metronidazole alone or as an adjunct to mechanical therapy in patients with chronic periodontitis. METHODS Studies were identified using MEDLINE and other sources. Meta-analyses were performed on the basis of probing depth (PD) at baseline and experimental and control regimens studied (i.e., metronidazole plus scaling and root planing [SRP] versus SRP and metronidazole versus SRP); the effect of local metronidazole on PD and attachment level (AL) was evaluated for follow-up times of 4, 8, 12, 24, and 36 weeks. The DerSimonian & Laird random effects model was used. RESULTS Twelve studies that met inclusion criteria were entered into the meta-analysis. A significant mean reduction in PD for the combined metronidazole and SRP was observed in all comparisons with initial PD > or = 4 mm (0.38 mm at 8 weeks to 0.6 mm at 12 weeks); whereas, with initial PD > or = 5 mm a significant mean reduction was observed from 12 weeks (0.29 to 0.48 mm at 24 and 36 weeks, respectively). Meta-analysis could be performed for AL to test the effectiveness of metronidazole as an adjunct to SRP and a significant AL improvement was found in all analyses (0.2 mm at 4 weeks to 0.29 mm at 24 and 36 weeks). Meta-analyses were performed including two to four studies. CONCLUSION Our results demonstrated the effectiveness of metronidazole as an adjunct to SRP in the treatment of chronic adult periodontitis, but clinical significance and dissemination of antibiotics should be taken into account in the evaluation of metronidazole as an alternative to SRP.

Abstract
OBJECTIVES The present controlled, single-blind study was performed to assess and compare the clinical healing and the microbiological findings following repeated intrasulcular applications of 1% metronidazole or 1% chlorhexidine gels in persistent periodontal pockets previously treated by scaling and root planing (SRP). MATERIAL AND METHODS Sixty-three systemically healthy subjects, 25 males and 38 females (mean age 48.4+/-7.2 years), diagnosed for chronic periodontitis were enrolled in this study. They underwent SRP and received oral hygiene instructions (OHI). Three months later, at baseline, a single persistent pocket with a probing depth (PD) of 5-9 mm was chosen as the experimental site in each patient; the subjects were stratified into three matched experimental groups on the basis of the treatment to be performed, which consisted of the subgingival administration of 1% metronidazole gel (MG, n=19), 1% chlorhexidine gel (CG, n=20) or placebo gel (PG, n=24). The treatments consisted of four repeated administrations of subgingival gels, each separated by 7 days, starting at the baseline. Clinical assessment was performed at the baseline and at the 180-day follow-up, after the end of treatment. For microbiological evaluations, subgingival plaque was sampled from the experimental sites at baseline, prior to the first subgingival gel administration, and at 7, 15, 30 and 90 days after the end of the treatment (days 28, 36, 51 and 111 from baseline). RESULTS Plaque accumulation did not change significantly in all three groups. Bleeding on probing and clinical attachment levels reduced in the MGs and CGs only. PD was significantly reduced by the same amount in all experimental groups. In the MGs and CGs a remarkable reduction in the frequencies of detection of several periodontopathic micoorganisms was recorded after the treatment. The same was not seen for the PGs. CONCLUSIONS Subgingival administration of MG or CG, both at 1%, may have a role in the management of persistent pockets during chronic periodontitis.

Abstract
Individual susceptibility to periodontal breakdown involves an interplay of genes, periodontal pathogens and other modulating factors. Anti-infective treatment, which includes oral hygiene measures, mechanical debridement, pharmacologic intervention and surgery, has been shown to be effective in arresting the progression of periodontal disease. Nevertheless, due to the chronic nature of the disease, susceptible individuals who are not maintained in a supervised recall program subsequent to the active treatment phase, show signs of recurrent destruction. Supportive periodontal therapy (SPT) is an integral part of periodontal treatment for patients with history of periodontitis, and is needed to prevent recurrence of disease in susceptible individuals. To prevent re-infection with periodontal pathogens, SPT includes elimination of dental plaque and bacteria from the oral cavity, thereby preventing the recurrence of pathogens into the gingival area. For individuals at risk of developing periodontitis, SPT should combine self-performed and professional anti-infective therapy, using mechanical and pharmacological means. The existing evidence suggests that the adjunctive use of antimicrobial pharmacologic therapy during SPT may enhance the results of mechanical debridement. The use of antimicrobials varies between patients, and is dependent on risk assessment and longitudinal monitoring of the clinical status of the periodontium.

Abstract
Aggressive periodontitis is characterized by a considerable attachment loss over a relatively short period of time. It may be the consequence of either the presence of highly aggressive pathogens or a highly susceptible host. In the first case, the use of antimicrobials should be beneficial in the treatment of those patients. However, due to the organization of the micro-organisms as a biofilm, the increasing incidence of allergies and resistance against antimicrobials and their side-effects, there is still controversy about their benefit in the treatment of periodontal disease. This paper discusses indications for the use of antimicrobials, the substances prescribed and the type of application under the conditions of aggressive periodontitis.

Abstract
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.

Abstract
AIM The aim of this single-blind, randomized, parallel-designed clinical trial (RCT) was to evaluate the clinical and microbiological effects of three sustained-release biodegradable polymers delivered into periodontal pockets following initial periodontal therapy. METHODS Forty-seven patients (28 females and 19 males) with a mean age of 51 years (range 29-71) underwent a periodontal examination at baseline (i.e. Week 0) and after 18 weeks. This included the assessment of the Plaque Index (PlI), Bleeding on Probing (BOP), Pocket Probing Depths (PPD) and Probing Attachment Levels (PAL) at six sites per tooth. Two to 4 months prior to baseline, all subjects had received initial periodontal therapy including motivation, instruction in oral hygiene practices and full-mouth scaling and root planing. At the treatment appointment (i.e. Week 2), the patients were randomly assigned to receive either Atridox trade mark, Elyzol Dental Gel or PerioChip at all residual periodontal pockets with a probing depth >/= 5 mm and concomitant BOP. In accordance with the manufacturer's recommendations, Elyzol Dental Gel was applied for a second time 7 days later. In addition to the clinical evaluation, subgingival microbiological samples were collected prior to treatment (i.e. Week 2) and at Weeks 4 and 18. Analysis of variance/covariance was used to evaluate changes from baseline to Week 18 for the clinical parameters. RESULTS Between the baseline and 18-week examinations, subjects treated with Atridox showed a significantly greater gain in mean PAL of 0.33 mm +/- 0.09 (SD) than subjects treated with Elyzol Dental Gel [0.03 mm +/- 0.09 (SD)](p = 0.03). However, the gain in PAL of 0.16 mm +/- 0.10 (SD) found after PerioChip application did not differ significantly from that obtained following the application of Atridox(p = 0.27). Of the sites treated with Atridox, 42% gained >/= 1 mm PAL and 9% >/= 2 mm PAL as opposed to the sites treated with Elyzol Dental Gel, in which 34% gained >/= 1 mm PAL and 8% gained >/= 2 mm PAL. Of the sites treated with PerioChip, 36% gained >/= 1 mm and 6% gained >/= 2 mm PAL following a completed initial periodontal therapy. CONCLUSIONS The application of the three biodegradable sustained release devices tested following initial periodontal therapy resulted in a statistically significant gain in mean PAL for AtridoxTM and a significant reduction in PPD for all three devices during the study period. Furthermore, when sites treated with Atridox were compared with sites treated with Elyzol, a significant difference in mean PAL gain (0.3 mm) was observed.

Abstract
AIM Evaluation of the clinical effect of topical application of doxycycline adjunctive to non-surgical periodontal therapy. METHODS A total of 111 patients suffering from untreated or recurrent moderate to severe periodontitis at 3 different centers (Heidelberg, Frankfurt, Nijmegen) were treated in this double-blind split-mouth study. In each patient, 3 different treatment modalities were assigned randomly to 3 test teeth: scaling and root planing alone (SRP), SRP with subgingival vehicle control (VEH), and SRP with subgingival application of a newly developed biodegradable 15% doxycycline gel (DOXI). At baseline, clinical parameters were measured at all single rooted teeth using a reference splint: PlI, PPD, relative attachment level (RAL-V), GI. 3 strata were generated according to baseline PPD: (i) 5-6 mm, (ii) 7-8 mm, (iii) > or =9 mm. Not more than 50% active smokers were allowed to each stratum. 3 and 6 months after therapy re-examination was performed by examiners blinded to baseline data and test sites. The statistical comparison of RAL-V gain and PPD reduction between the treatments was based on a repeated measures ANOVA with correction according to Huynh & Feldt. The comparison of SRP versus DOXI was considered as the main study question. RESULTS 110 patients finished the 3 months and 108 the 6 months examination. The study did not show adverse effects of VEH or DOXI except for one singular inflammation that occurred 2 months after application of the doxycycline gel. DOXI provided statistically significantly more favorable PPD reduction (SRP: -2.4+/-1.4 mm, VEH: -2.7+/-1.6 mm, DOXI: -3.1+/-1.2 mm; SRP versus DOXI p=0.0001, VEH versus DOXI p=0.0066) and RAL-V gain (SRP: 1.6+/-1.9 mm, VEH: 1.6+/-2.2 mm, DOXI: 2.0+/-1.7 mm; SRP versus DOXI p=0.027, VEH versus DOXI p=0.038) than SRP and VEH after 6 months. CONCLUSIONS Adjunctive topical subgingival application of a biodegradable 15% doxycycline gel was safe and provided more favorable RAL-V gain and PPD reduction than SRP alone and VEH. Thus, by use of topical doxycycline the threshold for surgical periodontal therapy might be moved toward deeper pockets.

Abstract
AIM The aim of this randomised, split-mouth, single-blind study was to determine the efficacy of controlled-release delivery of chlorhexidine gluconate 2.5 mg (PerioChip) in patients with residual bleeding pockets (>5 mm) at least 3 months following oral hygiene and root debridement phase therapy. MATERIAL AND METHODS 26 patients (non-smokers) were screened and potential study sites identified. Clinical parameters recorded at baseline and all subsequent visits were plaque index (PI), pocket probing depth (PPD), bleeding index (BI) and clinical attachment level (CAL). All study sites were debrided using ultrasonic instrumentation. PerioChips (PC) were placed in the selected sites of two quadrants (left or right) whilst identified sites in the remaining quadrants were left without adjunctive antimicrobial treatment. Clinical measurements were made at follow-up visits after 1, 3 and 6 months. Mean changes from baseline in PPD, BI and CAL were calculated with the patient as the experimental unit and comparability between the treatments was determined using t-tests. RESULTS At baseline there were no significant differences between PC and control sites for mean PI, PD, BI or CAL. The mean (SE) reductions in PPD for PC and control treatments were: 0.47 (0.1), 0.46 (0.1); 0.76 (0.1), 0.55 (0.1); 0.78 (0.1), 0.45 (0.1) for months 1, 3 and 6 respectively. Only at month 6 did the difference between treatments approach statistical significance (p=0.06). Mean (SE) reductions in CAL over the same periods were: 0.17 (0.1), 0.04 (0.08); 0.38 (0.1), 0.21 (0.1); 0.43 (0.1), 0.15 (0.09) p=0.048. Mean (SE) reduction in BI between PC and control treatments only reached statistical significance at 6 months: 1.08 (0.1), 0.59 (0.1) p=0.05. CONCLUSION These data suggest that PerioChip is beneficial for patients on maintenance therapy although the benefit is not apparent until 6 months after placement.

Abstract
The concept of locally delivering chemotherapeutic agents to the periodontal pocket as a method to treat periodontal disease has been studied for over 20 years. A number of locally delivered chemotherapeutic agents in periodontal therapy are either currently available or under investigation. Clinical efficacy derives from sustained-release technology to maintain an effective concentration of drug within the periodontal pocket for a clinically relevant length of time. Studied drugs have mainly been antimicrobials, both antibiotics and antiseptics. Most agents have been tested as adjuncts to scaling and root planing; a few have been studied as stand-alone monotherapies. Collectively, the data indicate that the use of locally delivered antimicrobials as adjuncts results in a significant increase in the reduction of probing depth compared with scaling and root planing alone. In other trials, results in reducing probing depth following the use of stand-alone locally delivered antimicrobials have been equivalent to those of scaling and root planing over a specified time. This Symposium was organized to present the current state-of-the-art with regard to the use of locally delivered antimicrobials in the treatment of periodontal disease. 5 experts in the field who have had considerable experience in studying locally delivered antimicrobials presented data. These speakers reviewed the clinical findings regarding efficacy of 5 different antimicrobial agents. An ensuing panel discussion was to consider treatment recommendations for locally delivered antimicrobials.

Abstract
Local delivery of antimicrobials has been investigated as a possible method for controlling and treating periodontal disease. A number of antimicrobial agents have been studied both as adjunctive therapies with scaling and root planing and as stand-alone chemotherapies. More recent investigations have focussed on the delivery of antimicrobials in sustained-release formulations designed to maintain effective concentrations of drug within the periodontal pocket. This article provides an overview of the development of the use of locally-delivered metronidazole in periodontal therapy and the current state-of-the-art of the technique. It is concluded that treatment with local delivery of metronidazole seems to be as effective as scaling and root planing in untreated as well as in recall subjects. However, there are reasons to suggest that local delivery of metronidazole should not be used as a substitute for conventional treatment of periodontal disease, since side-effects of long-term use and repeated use are not known. The antibiotic regimen should preferably be used as an adjunct to surgical and non-surgical therapy.

Abstract
This review article evaluates the role of local drug delivery systems in the management of periodontal diseases. The efficacy of several local delivery devices (i.e., tetracycline fibers, metronidazole and minocycline gels, chlorhexidine chips, and doxycycline polymer) which are either commercially available in the United States or abroad, or are currently under consideration for Food and Drug Administration (FDA) approval are discussed. The drug delivery systems are assessed with regard to their functional characteristics, effectiveness as a monotherapy, as compared to scaling and root planing, and ability to enhance conventional therapy. Furthermore, controversies associated with local delivery are addressed (e.g., induction of bacterial resistant strains, the efficacy of systemic versus local drug delivery, and whether local drug delivery should function as an alternative or as an adjunct to conventional treatment).
