ABSTRACT
Introduction: The main goal of the root-end filling material is to create a hermetic seal to protect against microbes and their by-products. Excellent biocompatibility and sealing ability are characteristics of MTA developed by Torabinejad et al. This study aimed to compare the sealing ability of different type MTA as root-end filling material using dye penetration technique. Material and Method: One-twenty (N = 120) extracted human maxillary anterior teeth were decontaminated, cleaned, and decoronated. Endodontic treatment and root-end resection were done. Then root-end cavity was prepared and filled with tested materials (N = 30). A calibrated stereomicroscope was used to evaluate linear measurement. All data were tabulated and statistically analyzed with a level of significance set at P < .05. Result: This order of increasing microleaks was observed: MTA Angelus < MTA Plus < PRO-Root MTA < Control group. There was a statistically significant difference in mean microleakage in MTA Angelus and MTA Plus groups (P = 0.040). MTA Angelus shows the least microleakage among all the bioceramic material groups. Conclusion: Although the sealing ability of MTA Angelus is superior to MTA Plus, PRO-Root MTA. MTA Plus, PRO-Root MTA could be considered an acceptable alternative to MTA Angelus in peri-radicular surgeries.
ABSTRACT
BACKGROUND: Exact diagnosis, efficient cleaning, shaping as well as disinfection of the root canals lead to successful root canal treatment. The present study compared three different irrigating systems in root canal treatment. METHODOLOGY: Sixty recently extracted permanent mandibular molars were classified into four groups: Group I, II, III, and IV with 15 teeth each. Group I comprised Endo-Irrigator Plus system. Group II comprised EndoActivator, Group III utilized passive ultrasonic irrigation (PUI), and Group IV was control, in which no activation of the irrigant was done. Stereomicroscope (X20) magnification was used for checking isthmus cleanliness. The scoring criteria were divided into score 1-5 depending on the amount of debris in root canal walls. RESULTS: The mean ± standard deviation debris removal score in Group I was 2.6 ± 0.80, in Group II was 3.8 ± 0.72, in Group III was 3.9 ± 1.06, and in Group IV was 4.2 ± 0.82. The difference was significant (P < 0.05). CONCLUSION: Authors found that Endo-Irrigator Plus exhibited better cleaning efficacy followed by EndoActivator and PUI.
ABSTRACT
The coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in liver transplantation because of concerns regarding safety and healthcare resource utilization. There are scant data regarding the safety, optimal timing, and preferred postsurgical immunosuppression regimens for liver transplantation in patients recovered from COVID-19 infection. We describe our experience with one of the first reported cases of orthotopic liver transplantation in a patient who had recently recovered from COVID-19 infection. Using our experience as an example, orthotopic liver transplantation in patients that have recovered from COVID-19 may be safe.
