Comparing suture strengths for clinical applications: a novel in vitro study.
The purpose of this study was to compare the tensile strengths of commonly used sutures over a 2-week period under simulated oral conditions. ⋯ 4-0 sutures are stronger and have greater tensile strength than 5-0 sutures. CG seems to sustain its strength better than PG and PG-FA after 2 weeks. PG-FA may not be a desirable suture if tensile strength is required after 10 days. Appropriately designed clinical studies are necessary to confirm this finding in an in vivo environment.

Randomized Controlled Trial Comparative StudyAmoxicillin and metronidazole as an adjunct to full-mouth scaling and root planing of chronic periodontitis.
It has been suggested that scaling and root planing of all pockets within a few hours and chlorhexidine treatments (full-mouth disinfection) may reduce the need for supplementary therapies. The aim of this study was to evaluate the clinical benefit of amoxicillin and metronidazole administered immediately after completion of full-mouth periodontal debridement in patients with chronic periodontitis. ⋯ Systemic metronidazole and amoxicillin significantly improved the 6-month clinical outcomes of full-mouth non-surgical periodontal debridement, thus significantly reducing the need for additional therapy.

Aggressive periodontitis and chronic arthritis: blood mononuclear cell gene expression and plasma protein levels of cytokines and cytokine inhibitors.
Cytokines and cytokine inhibitors have been associated with many immunoinflammatory diseases. In the present study, we examined whether peripheral blood mononuclear cell (PBMC) gene expression mirrors the corresponding plasma levels of clinically important pro- and anti-inflammatory cytokines and cytokine receptors in patients with periodontitis and patients with arthritis representing two examples of chronic inflammatory diseases, such as periodontitis and arthritis. To identify possible disease-specific characteristics of subjects with periodontitis relative to subjects with chronic inflammation in general, patients with arthritis (juvenile idiopathic arthritis [JIA] and rheumatoid arthritis [RA]) were included. ⋯ The study demonstrated only a few changes in the PBMC expression of various cytokine and cytokine inhibitor genes in aggressive periodontitis and chronic arthritis compared to controls. There were a few similarities among disease groups, and no direct and simple correlation between cellular transcripts and proteins was found.

Review Case ReportsSynchronous metastatic melanoma presenting as gingival and facial swelling: a case report and review of the literature.
Metastases to the oral cavity are unusual, and most cases affect the jaws. The clinicopathologic features of a metastatic melanoma involving the mandibular gingiva and facial skin are described. ⋯ To the best of our knowledge, this is the first English-language report of metastatic melanoma affecting the gingiva and facial skin concomitantly. The intraoral involvement of disseminated melanoma indicates a very poor prognosis, as confirmed by the current case.

Randomized Controlled Trial Comparative StudyChlorine dioxide and chlorhexidine mouthrinses compared in a 3-day plaque accumulation model.
The aim of this study was to investigate the inhibiting effect of a chlorine dioxide mouthrinse as opposed to a mouthrinse containing chlorhexidine (0.20%) during 3 days of plaque accumulation. ⋯ Chlorine dioxide mouthrinse seems to be a less potent plaque inhibitor than chlorhexidine.
