Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT

Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging from 15 to 72 years) with 522 endodontically treated teeth that were assessed for technical quality of the root canal filling and periapical status of the teeth. Additionally, the apical status of each root-filled tooth was assessed according to the gender, dental arch, tooth type and age classification, undetected canals, instrument fracture, root fracture, apical resorption, apical lesion, furcation lesion and type and quality of the coronal structure. Statistical analysis was performed using percentages and chi-square test. Results The success rate of the root canal treatment was of 54.4%. The success rates of adequate and inadequate root canal treatment were not significantly different (p>0.05). Apical periodontitis was found in 228 (45.6%) teeth treated for root canals. Higher prevalence of AP was found in patients aging from 20 to 29 years [64 (27%) teeth] and in anterior (canines and incisors) teeth [97 (41%) teeth]. Conclusions The technical quality of root canal filling performed by dental practitioners in a Turkish subpopulation was consistent with a high prevalence of AP. The probable reasons for this failure are multifactorial, and there may be a need for improved undergraduate education and postgraduate courses to improve the clinical skills of dental practitioners in endodontics

Introduction: Anemia is known to be an important problem in burn injury. We aimed to investigate the protective effect of Solanum tuberosum (potatoes), against abnormal breakdown of erythrocytes in burn injury. Methods: Ninety-six male (9 to 10 weeks old) Swiss Albino mice (34–40 g) were included into the study, which consisted of two phases: dose optimization phase (n = 48) and study phase (n = 48). Half of the mice were given S. tuberosum juice (study group) and the other half drinking water (control group). The optimal dosage causing minimum decline in hematocrit was as follows: 1.6 mL/kg at 0 h, 0.8 mL/kg at 24 hours, and 0.8 mL/kg at 36 hours of burn injury. The burn injury was induced with a solid 10-mm aluminum bar heated in boiling water. Results: The decrease in hematocrit level was significantly lower in the study group than the control group at 24 and 48 hours (P = 0.05 and P = 0.023, respectively). The increase in anisocytosis, a hemolytic anemia sign, was also significantly lower in the study group than the control group at 48 hours (P = 0.021). There was no significant difference between groups in terms of clotting time or the bleeding time. Conclusion: In burn injury, S. tuberosum may be beneficial against anemia and it may reduce the need for red blood cell transfusion
