Title:  In vivo evaluation of periodontal microcirculatory changes associated with endodontic treatment

Abstract:  Aim The purpose of this study was to investigate in vivo the gingival microcirculatory changes associated with endodontic treatment using the continuous wave of condensation technique. Materials and methods Twenty necrotic one canal roots of 20 cooperative patients of both sexes, aged between 20 and 43 years, were selected. All patients were examined by capillaroscopy before, immediately after endodontic treatment, and after 7 days. The last examination was carried out by the same operator, and repeated twice for each examined area: masticatory, buccal and labial mucosa corresponding to the endodontically treated root. All canals were prepared using a simultaneous technique with Ni-Ti files (MTwo files). Results The images of the masticatory mucosa after root canal obturation showed evident micro-areas of extravasation, with significant bleeding and angio-morphological alterations due to heat. One hour after the endodontic treatment evident extravasation was observed, but a decrease of all altered parameters, was present. After seven days from treatment, in the periodontal tissues, a complete healing was observed. The in vivo evaluation of the vascular pattern during root canal obturation with System B showed that the high temperature in the canal determines visible effects on the vasculature of adjacent sites. It was found that microangiotectonic alterations decrease up to a complete healing after 7 days from treatment. Conclusion All the changes in microcirculation, due to thermal shock of periodontal tissues, are reversible.
