The aim of the present study was to evaluate the treatment with amoxicillin or metronidazole in comparison to scaling and root planing in the treatment of chronic periodontitis. Randomised clinical trials were searched in the databases MEDLINE, EMBASE, SciELO, Cochrane and Scopus from 1989 to 2010. The search started with 2895 articles. From this initial number of articles, 10 publications were selected and included in the study according to fixed criteria. Studies included adult patients of both sexes aged between 21 and 80, diagnosed with chronic periodontitis and treated with amoxicillin and/or metronidazole or scaling and root planning. From each article, details were abstracted relating to sample size, design, sex, age, oral hygiene habits, the exposure to drug (doses, schedule), and results such as clinical effect, analysis methods, stratification variables. CONCLUSION: this meta-analysis showed absence of statistically significant difference between the effects studied.

    • "There is a link between periodontitis and systemic diseases such as diabetes and cardiovascular disease, which seriously impact patients' quality of life 2. The ultimate goal for the treatment of periodontitis is to reconstruct the periodontal tissue and its functions by regenerating periodontal tissue 3. Several methods have been developed to treat periodontitis, such as guided tissue regeneration, scaling and root planning, demineralized freeze-dried bone allografts, autografts, and the use of bioactive materials 4-6. However, these treatments have had limited success because they do not effectively regenerate periodontal tissue 7. "

    ABSTRACT: Periodontal ligament stem cells (PDLSCs) with bone morphogenic ability are used to treat diseases such as periodontitis. Their treatment potential is increased when used in combination with proteins that induce osteogenic differentiation. For example, bone morphogenetic protein-9 (BMP9) has been found to have potent osteogenic activity. In the present study, PDLSCs were isolated from human periodontal membrane and infected with recombinant adenoviruses expressing BMP9 (Ad-BMP9). Levels of osteogenic markers such as runt-related transcription factor 2 (Runx2), alkaline phosphatase (ALP), osteopontin (OPN), and osteocalcin (OCN) as well as mineralization ability were measured. The results showed that BMP9 promoted bone formation of PDLSCs. In other experiments, SB203580 and PD98059, which are inhibitors of p38 and ERK1/2, respectively, were used to determine if these kinases are involved in the osteogenic differentiation process. The resulting protein expression profiles and osteogenic markers of PDLSCs revealed that the mitogen-activated protein kinase (MAPK) signaling pathway might play an important role in the process of BMP9-induced osteogenic differentiation of PDLSCs.

    ABSTRACT: Background: The combination of Amoxicillin and metronidazole (AMX/MET) as an adjunctive treatment to scaling root planing (SRP) has been proposed for the treatment of chronic periodontitis; however, its effectiveness and clinical safety remain to be defined. The purpose of the present meta-analysis is to assess the effectiveness of SRP + AMX/MET compared to SRP alone. Methods: An electronic search of eight databases from their earliest records through October 8, 2011 and a hand search of international dental journals for the last 15 years were conducted. Gain in clinical attachment level (CAL), reduction in probing depth (PD), secondary outcomes, and adverse events were analyzed. A random-effect model was used to pool the extracted data. The weighted mean difference (WMD) with 95% confidence interval (CI) was calculated for continuous outcomes; heterogeneity was assessed with the Cochrane χ(2) and I(2) tests. The level of significance was set at P <0.05. Results: After the selection process, four randomized clinical trials were included. Results of the meta-analysis showed significant CAL gain (WMD = 0.21; 95% CI = 0.02 to 0.4; P <0.05) and PD reduction (WMD = 0.43; 95% CI = 0.24 to 0.63; P <0.05) in favor of SRP + AMX/MET. No significant differences were found for bleeding on probing (WMD = 10.77; 95% CI = -3.43 to 24.97; P >0.05) or suppuration (WMD = 1.77; 95% CI = -1.7 to 5.24; P >0.05). Conclusion: The findings of this meta-analysis seem to support the effectiveness of SRP + AMX/MET; however, future studies are needed to confirm these results.

    ABSTRACT: Background/Purpose The evidence base regarding the causal relationship between oral biofilm and the host inflammatory response to the etiology of periodontal disease has substantially increased over the years. What has not changed significantly during that time is the conservative manner in which the disease can be treated with periodontal debridement (PD). Since dental hygienists, in particular, specialize in providing these procedures it is important to evaluate the evidence that supports periodontal debridement as a primary and fundamental treatment modality Method An extensive narrative literature review that included systematic reviews, examined traditional PD, the use of adjuncts to enhance PD and newer PD procedures to determine what are the best practices for achieving optimal clinical outcomes. Conclusion Compared to surgical therapy, PD results in maintenance of attachment levels over time, but is not as effective in the initial reduction of probing depths in deep pockets. Sustained release local drug delivery agents have some modest adjunctive effects when used with PD, as do systemic antibiotics in aggressive periodontitis cases. Reported analyses of the long term effects of chemotherapeutic agents usually do not extend beyond a few months to a year. While laser therapy is still under investigation it remains as a potential PD therapy. . New instruments being refined to better visualize the root surface either non-surgically or with mini papilla reflection flaps, hold promise for the future when they become more affordable and accessible. Despite the development of new technology, it still appears that periodontal debridement (PD) remains the gold standard for the treatment of inflammatory periodontitis.
