Systemic Metronidazole (systemic + metronidazole)
Selected AbstractsIncomplete adherence to an adjunctive systemic antibiotic regimen decreases clinical outcomes in generalized aggressive periodontitis patients: a pilot retrospective studyJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2007Adrian Guerrero Abstract Aim: The objective of this study was to explore the effect of incomplete adherence to the prescribed antibiotic regimen, amoxicillin and metronidazole, in the non-surgical treatment of generalized aggressive periodontitis (GAP). Methods: This retrospective study included 18 GAP subjects who received a conventional course of full-mouth non-surgical periodontal treatment using machine-driven and hand instruments and an adjunctive course of systemic antibiotics (500 mg amoxicillin and 500 mg metronidazole three times a day for 7 days). Clinical parameters were collected at baseline and at 2 months post-treatment. Self-reported adherence to the prescribed medication regimen was recorded at 2 months. Results: All clinical parameters, except for the mean clinical attachment level (CAL) in sites with initial probing pocket depth (PPD) 3 mm, improved at 2 months in all subjects. PPD reduction was 3.7 mm [95% confidence interval (CI) 3.2, 4.3 mm] in deep pockets (7 mm) and 2.2 mm (95% CI 1.9, 2.4 mm) in moderate pockets (4,6 mm), while CAL gain was 2.2 mm (95% CI 1.7, 2.6 mm) and 1.2 mm (95% CI 0.8, 1.5 mm), respectively. However, only 11 subjects (61.1%) reported full adherence to the medication. In deep pockets (7 mm), the difference between an adherent and non-adherent/partially adherent subject was 0.9 mm (95% CI 0.1, 1.7 mm, ancova, p=0.027) in PPD reduction and 0.8 mm (95% CI ,0.2, 1.9, p=0.129) in CAL gain at 2 months. In moderate pockets (4,6 mm) this difference was smaller in magnitude: 0.4 mm (95% CI 0.1, 0.9 mm, p=0.036) in PPD reduction and 0.2 mm (95% CI ,0.3, 0.9 mm, p=0.332) in CAL gain. Conclusions: Within the limits of this design, these data suggest that incomplete adherence to a 7-day adjunctive course of systemic metronidazole and amoxicillin is associated with decreased clinical outcomes in subjects with generalized aggressive periodontitis. [source] Adjunctive benefits of systemic amoxicillin and metronidazole in non-surgical treatment of generalized aggressive periodontitis: a randomized placebo-controlled clinical trialJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2005Adrian Guerrero Abstract Background: The objective of this study was to assess the adjunctive clinical effect of the administration of systemic amoxicillin and metronidazole in the non-surgical treatment of generalized aggressive periodontitis (GAP). Methods: Forty-one systemically healthy subjects with GAP were included in this 6-month double-blind, placebo-controlled, randomized clinical trial. Patients received a course of full-mouth non-surgical periodontal treatment delivered over a 24 h period using machine-driven and hand instruments. Test subjects received an adjunctive course of systemic antibiotic consisting of 500 mg amoxicillin and 500 mg metronidazole three times a day for 7 days. Clinical parameters were collected at baseline, and at 2 and 6 months post-treatment. Results: In both the test and the placebo groups, all clinical parameters improved at 2 and 6 months. In deep pockets (7 mm), the test treatment resulted in an additional 1.4 mm (95% confidence interval 0.8, 2.0 mm) in full-mouth probing pocket depth (PPD) reduction and 1 mm (0.7, 1.3 mm) of life cumulative attachment loss (LCAL) gain at 6 months. In moderate pockets (4,6 mm), the adjunctive benefit was smaller in magnitude: PPD reduction was 0.4 mm (0.1, 0.7 mm) and LCAL gain was 0.5 mm (0.2, 0.8 mm). In addition, the 6-month data showed LCAL gains 2 mm at 25% of sites in test patients compared with 16% in placebo (p=0.028). Similarly, PPD reductions of 2 mm or more were observed in 30% of sites in test and 21% of sites in placebo patients. Seventy-four percent of pockets with PPD 5 mm at baseline were 4 mm or shallower at 6 months in the test group. This compared with 54% in the placebo group (p=0.008). Disease progression at 6 months was observed at 1.5% of test and 3.3% of sites in test and placebo, respectively (p=0.072). Conclusions: These data indicate that a 7-day adjunctive course of systemic metronidazole and amoxicillin significantly improved the short-term clinical outcomes of full-mouth non-surgical periodontal debridement in subjects with GAP. [source] Scaling and root planing, systemic metronidazole and professional plaque removal in the treatment of chronic periodontitis in a Brazilian population II , microbiological resultsJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2005L. H. Carvalho Abstract Objective: The current investigation evaluated changes in levels and proportions of 39 bacterial species in subgingival plaque samples after scaling and root planing (SRP) alone or in combination with systemic metronidazole and/or professional cleaning in subjects with chronic periodontitis. Methods: Forty-four adult subjects (mean age 45±6 years) with periodontitis were randomly assigned in four treatment groups, a control (C, n=10) that received SRP and placebo and three test groups treated as follows: T1 (n=12): SRP and metronidazole (M, 400 mg tid) for 10 days; T2 (n=12): SRP, weekly professional supragingival plaque removal for 3 months (PC) and placebo; and T3 (n=10): SRP, M and PC. Subgingival plaque samples were taken from seven sites per subject at baseline and 90 days post-therapy. Counts of 39 subgingival species were determined using checkerboard DNA,DNA hybridization. Significance of differences over time was determined using the Wilcoxon signed ranks test and among groups using ancova. Results: The mean counts of the majority of the species were reduced post-therapy in the 4 treatment groups. Counts (× 105±SEM) of Porphyromonas gingivalis, Tannerella forsythensis and Treponema denticola were significantly reduced in groups T2 and T3. Levels of beneficial species, such as some Actinomyces species, Veillonella parvula, Streptococcus sanguis, Streptococcus oralis and Streptococcus gordonii were minimally affected in levels when the combined therapy was applied (T3). Mean proportions of red complex species decreased from 18.4% at baseline to 3% at 90 days post-therapy in group T3 (p<0.01), from 25.8% to 2.3% in group T2 (p<0.01), from 17.7% to 5.6% in group T1 (p<0.05) and from 19.4% to 8.8% in group C (NS). Proportions of the suspected periodontal pathogens from the orange complex were also markedly reduced in groups T2 and T3. Conclusions: All treatments reduced counts and proportions of red complex species. Adjunctive therapy appeared to have a greater effect and also affected members of the orange complex.

This report details the implant placement outcomes in three patients with pre-existing oral mucosal disease. Case reports,A: Four implants were placed in the lower anterior region of a 78-year-old female with longstanding mucous membrane pemphigoid (MMP) in 2004. The MMP had resulted in extensive cicatrisation of the upper and lower buccal and labial vestibules. One implant failed to osseointegrate, but was successfully replaced. There have been no other postplacement adverse events, despite the MMP remaining mildly active. B: A 36-years-old male with orofacial granulomatosis characterised by recurrent lip swelling and gingival enlargement, had a single implant placed in the upper canine region in 2001. Although still in situ significant peri-implant alveolar bone loss has occurred and has been stabilised by repeated debridement, local administration of topical minocycline and several courses of systemic metronidazole. C: A 53-years-old female with oral manifestations of diffuse systemic sclerosis and fibrosing alveolitis had four lower anterior mandibular implants placed in 1995 to support an 8 unit bridge. One episode of peri-implant inflammation was controlled with local debridement and topical chlorhexidine mouthrinse. The implants remain satisfactory 11 years postinsertion. Conclusion, The short-term failure of osseointegrated implant integration appears uncommon in patients with non-malignant oral mucosal disease. There remains a need to establish appropriate case selection criteria and monitor outcomes. [source] Severe necrotizing stomatitis and osteomyelitis after chemotherapy for acute leukaemiaAUSTRALIAN DENTAL JOURNAL, Issue 3 2009FA Santos Abstract Background:, Leukaemia is a malignant neoplasm characterized by clonal proliferation of white blood cells within the bone marrow. Despite an increase in the white blood cell count, the leukaemic leukocytes are non-functional. The oral complications arising in leukaemic patients can be attributed to the direct and indirect effects of immunosuppressive chemotherapy. Methods:, This case report describes severe maxillary and mandibular necrotizing stomatitis and osteomyelitis in a young female patient after chemotherapy for acute leukaemia. On physical examination, the patient presented malnourished with pale skin, cervical lymphadenitis, frequent fever and generalized pain. The intra-oral clinical examination found halitosis, multiple ulcers, necrotizing stomatitis and osteomyelitis located in the maxillary and mandibular regions. The necrotizing stomatitis and osteomyelitis were treated locally with atraumatic removal of the necrotized tissues. The patient received a daily preventive protocol consisting of oral hygiene care, including twice daily brushing, and mouthrinses with a solution of chlorhexidine. She was also treated with systemic metronidazole and amoxicillin for 21 days. Results:, During the course of management the patient's oral condition improved with some re-epithelialization being noted. However, severe alveolar bone destruction remained evident. Thirty-two months after presentation of the initial symptoms, the patient died due to complications related to leukaemia recurrence (haemorrhage, sepsis and respiratory distress syndrome). Conclusions:, Dental monitoring during cancer treatment is imperative in order to emphasize the importance of dental plaque control and the maintenance of a healthy periodontal condition throughout medical treatment.
