Evaluation of leakage of bacteria and endotoxins in teeth treated endodontically by two different techniques
No full textRoot canal recontamination occurs after contact between oral-bacterial flora and the coronal extremity of the root canal. The aim of this study was to evaluate the time required for endotoxins and bacteria to penetrate through root-canal obturations performed with vertical and lateral gutta-percha condensation techniques. Specimens prepared by the two alternative methods were exposed to contaminated saliva, and leakage into the root was evaluated over time. None of the obturated roots was infiltrated by endotoxins after 31 days. On the contrary, between day 13 and day 37 bacteria had infiltrated all specimen

No full textThe chromatic stability of nonvital discolored teeth, subjected to the combined
intracoronal bleaching technique and to endodontic treatment, was evaluated at a
distance of 16 yr (1989-2005). The series comprised 50 patients (age range 7-30
yr) selected from among those attending the Dental Clinic at "Federico II"
University, Naples, between 1987 and 1989. After 16 yr, only 35 cases could be
evaluated: in 22 of these cases (62.9%) the color had remained stable and was
similar to that of adjacent teeth, indicating a successful outcome of the
combined bleaching technique. There were 13 cases (37.1%) classified as failures
because of marked color relapse. Radiology showed none of the cases re-examined
to have undergone internal or external root resorption. These results confirm the
validity of the combined intracoronal bleaching technique in terms of efficacy,
rapid esthetic result, and safety
