Microbioti associati alla Parodontite Refrattaria al Trattamento: prevalenza ed antibiotico sensibilita
No full textBACKGROUND: The aim of the present study was to analyze the composition of subgingival microflora in patients with refractory periodontitis and to evaluate the antimicrobial sensitivity of isolated periodontopathic microorganisms to different antibiotics. METHODS: Eleven subjects with a mean age of 46.4 years were selected for the present study. All had been treated for periodontal disease in the past. After further disease progression patients were included in this study. Eight subgingival plaque samples per patients were collected for cultural analysis. RESULTS: "Black pigmenting anaerobic bacilli" were the pathogenic microorganisms more frequently isolated. The findings from antibiotic susceptibility test showed that high number of bacteria associated with refractory periodontitis resulted resistant to erythromycin, metronidazole and tetracycline. The most effective antibiotics were ciprofloxacin, amoxicillin-metronidazole and amoxicillin-clavulanic acid. CONCLUSIONS: Microbiological analysis and antibiotic susceptibility test should be considered important tools in the management of patients with poor clinical response to conventional periodontal treatment.INGLES

No full textThe present experimental study has been undertaken in order to analyze the influence of bacterial recolonization on periodontal wound healing following guided tissue regeneration therapy in humans. Two different surgical techniques has been carried out: one using a non absorbable membrane and the other a absorbable one. Microbiological data indicate no statistically significant difference between the techniques employed. Furthermore our data have confirmed the necessity of maintaining the healing sites free from the main periodontal pathogens
La ricolonizzazione batterica nella rigenerazione guidata dei tessuti parodontali interradicolari. [Bacterial recolonization in the guided regeneration of the inter-radicular periodontal tissues]
No full textAbstract
The present experimental study has been undertaken in order to analyse clinically and microbiologically the formation of new periodontal attachment in class II furcation lesions in mandibular molars, comparing healing after surgical conventional therapy and after guided periodontal tissue regeneration technique using non-resorbable membranes and evaluating at the same time, with cultural anaerobic technique, the influence on healing of the bacterial recolonization of some periodontally pathogenic species. Clinical results have demonstrated that, after therapy, may occur a certain discrepancy between soft and hard tissue regeneration and that the bone tissue shows a different pattern of apposition in the horizontal and vertical direction. Microbiological data have underlined the significance of surgical instrumentation in the guided inter-radicular periodontal tissue regeneration and have confirmed the necessity of maintaining the healing sites free from the main periodontal pathogens
