Filter by:Recognition of community profiles in endodontic infections may allow a better understanding of the pathogenesis of the disease and the establishment of more effective treatment protocols. Therefore, the aim of the present study was to investigate bacterial diversity in endodontically infected primary and permanent teeth using 16S rRNA gene sequencing and QIIME 2TM (Quantitative Insights Into Microbial Ecology 2) bioinformatics pipeline
This study was conducted to evaluate clinical and radiographical outcome of using a standardized platelet-rich plasma (PRP) biomembrane following endodontic surgery and its correlation with the growth factors content in this concentrate.
The aim of this study is to evaluate the quality of obturation and the time efficiency of rotary versus manual instrumentation in roots of deciduous molars clinically where the: - Primary objective Is to evaluate the time efficiency - Secondary objective Is to evaluate the quality of obturation Clinical and radiographical follow up will be performed for 18 months to investigate the clinical and the radiographic success for the Conventional and Rotary groups.
This study was conducted to determine the antibacterial affect of three different solutions used as final irrigant during endodontic therapy. The investigator's objective was to compare the antibacterial affect of relatively new final irrigant QMix with EDTA and Qmix with EDTA+CHX by evaluating the bacteriological status of the root canal before and after use of the final irrigant.
The pulp therapy in primary teeth is still necessary even with all odontopediatrics evolution in prevention and minimal intervention, aiming to keep the tooth free of inflammation or infection and in a functional state until its exfoliation. Several materials are used as filling paste of primary teeth. In Brazil, the Guedes-Pinto Paste (PGP), an association of iodofórmio, camphorated paramonochlorophenol, prednisolone and rifamycin, has been widely used for some decades. However, current Brazilian legislation has made it difficult to commercialize antibiotics, which has made it difficult to obtain the ointment that is the association between prednisolone and rifamycin. Therefore, the objective of this clinical trial will be to test PGP without rifamycin in the pulpectomy of primary teeth, and to compare it with the treatment performed with conventional PGP.
Aim To evaluate in vivo the shaping ability of the canal with 3 different single-file systems: Reciproc Blue, WaveOne Gold and XP Endo-Shaper, using cone beam computed tomography and 3D reconstructions to measure canal volume increase, centering ability of the instruments and canal transportation in human premolars in vivo. Methodology Thirty human lower premolars were randomly divided into three groups, in which root canals were prepared using one of these single-file systems: Reciproc Blue, WaveOne Gold, and XP EndoShaper. Root canals were scanned before and after root canal preparation by using CBCT and 3D reconstruction was carried out to evaluate canal volume increase, centering ability of the instrument and canal transportation for each group. Statistical analysis was made for each variable to determine statistically significant differences between groups.
Trial is designed to allow revascularization and tissue engineering in necrotic teeth with peripical lesion in a single visit approach. different disinfection protocols is used to ensure that adequate disinfection of root canals is achieved to allow stem cells to differentiate and proliferate generating pulp like tissue and turning back tooth to live with periapical healing of resorbed bone.
• Grouping: The patients will be randomly assigned into two equal groups Group : OneShape Group: ProtaperNext - Endodontics procedure steps: 1. Patient will be anesthetized by using infiltration local anesthesia or nerve block according to the tooth location in mandibular or maxillary arch respectively. 2. All caries will be removed, then isolation using rubber dam, the crown and surrounding structures will be disinfected with 30% H2O2( hydrogen peroxide) for 30 seconds, followed by 2.5% NaOCl for the same period of time and then inactivated with 5% sodium thiosulphate. 2- For the access cavity preparation, a sterile/apyrogenic high-speed diamond bur will be used in conjunction with manual irrigation with sterile saline. Before entering the pulp chamber, the access cavity will be disinfected according to the protocol described above. 2- Root canal length will be determined, by preoperative radiograph then (S1) will be taken by introducing a sterile/apyrogenic paper point #15/ 20 (5paper points) into the full length of the canal and left there for 1 minute. Then, the sample will be placed in an apyrogenic glass and stored in -20°. Then canal length will be confirmed by apex locator. 3- Cleaning and shaping will be done using either One shape or Protaper next rotary instruments in crown down preparation technique with the use of in an endodontic motor according to the manufacturer instructions, the canals will be thoroughly irrigated using 3ml of 2.5% Sodium hypochlorite between every subsequent instrument. 4-After root canal preparation, NaOCl will be inactivated with 5 mL of sterile 5% sodium thiosulphate for 1 minute, which then will be removed with 5 mL of sterile/apyrogenic saline solution., which then will be removed with 5 mL of sterile/apyrogenic saline solution. second endotoxin sample (S2) will be taken from the root canals. (5 paper point size of the master cone). 5- After completion of instrumentation and irrigation, obturation will be done using size 30/ 0.4 taper gutta-percha cones and auxiliaries as needed using the modified single cone technique. Determination of Endotoxin Concentration Human endotoxin (ET) ELISA Kit will be used to measure endotoxin concentrations in the root canals before and after chemomechanical procedures.
This is a clinical study that will investigate the occurrence of post-operative discomfort following the use of the Gentlewave System for root canal disinfection and irrigation. Assessment of discomfort level will be via a visualized analog pain scale.
Aim of the study: To compare Formocresol and Biodentine clinically and radiographically when used for pulpotomy of primary molars Study Design : A randomized control clinical trial (split mouth and double blind) was conducted on 43 (4-6 years-old) children with decayed vital mandibular primary molars which were treated by pulpotomy using both medicaments . All treated teeth were followed for one year (at 3, 6, 9 and 12 months clinically and at 6 and 9 radiographically).
