RESUMO

BACKGROUND: The main target of periodontal disease and alveolar bone defeat treatment is the regeneration of the lost structures. AIM: This work deals with the evaluation of the effect of functionalised multi-walled carbon nanotubes (MWCNTs), as grafting material in the management of furcation defects created in dogs. MATERIAL AND METHODS: Potential cytotoxicity of the grafting material was assessed. Scanning electron microscope (SEM) and energy dispersive x-ray (EDX) analysis after incubation of the grafting material in simulated body fluid (SBF) at pH 7.4 and 37°C for one week was done. In six healthy mongrel dogs' full-thickness mucoperiosteal flaps were raised on the buccal aspects to create two walls intrabony defects at the furcation areas. The mandibular premolar area received the grafting material. Histological evaluation was carried out at 1, 2- and 3-months' period. RESULTS: Cytotoxicity results proved the safety of grafting material application. The prepared material exhibited good Ca-apatite crystal patterns at the surface revealed by SEM and high calcium content showed by EDX results. Good bone formation ability was also apparent histologically. CONCLUSION: The prepared grafting material (MWCNTs) can serve as a delivery vehicle for osteogenic cells and osteogenic growth factor proteins in the bone development process.

RESUMO

INTRODUCTION: Knowledge about the pathogenic process in the progression of periodontal disease indicates that the central cause of periodontal disease is the loss of a healthy balance between microbial virulence factors and the host's inflammatory response. The aim of this study was to evaluate the potential effectiveness of diacerein as an anti-inflammatory drug in the management of experimental periodontitis in rats. METHODS: The study included 60 albino rats that were divided into two groups. Periodontitis was induced in both groups. The drug group received systemic administration of diacerein, and the control group received a placebo. IL-1ß was measured two weeks after the induction of periodontitis and before the administration of the drug (baseline measurement), and it was measured again at the end of two and end of four weeks after scaling and root planning and diacerein administration. RESULTS: The results indicated that there was a significant decrease in IL-1ß level in both groups. For the control group, there were significant decreases of the IL-1ß values from the baseline to two weeks and also from the baseline to four weeks, with p-values of 0.0001 for both comparisons. The same results were obtained for the drug group. CONCLUSION: It was concluded that it is likely that diacerein may play a therapeutic role as a potent anti-inflammatory drug in the management of periodontitis.
