Filter by:Till date, no study has systematically evaluated the role of a single variable on success of endodontic retreatment. While the evaluation of a single factor as the primary objective in a study is a difficult task, it unarguably provides more valuable information regarding the influence of that variable on outcome. The clinical studies comparing the use of Sodium hypochlorite (NaOCl) and Chlorhexidine digluconate (CHX) in retreatment cases have evaluated only the antibacterial effectiveness and there is no clinical study comparing their effect on the clinical outcome in retreatment cases. And also, no study has compared the use of irrigant as single variable in the primary objective on success of retreatment cases. The conclusions drawn from such "surrogate measures" must be interpreted and applied in clinical settings with caution. Since there is no standardised irrigation treatment protocol for secondary root canal treatment, the present study is being conducted to evaluate the effect of 5% NaOCl with 17% Ethylenediaminetetraacetic acid (EDTA) and 2% CHX with 10% citric acid (CA) on outcome, when used as irrigants during the chemomechanical preparation in retreatment cases.
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.
The main goal of root canal treatment is the removal of existing microorganisms and the prevention of introducing new ones to the root canal system. This will require the application of strict aseptic measures. Microorganisms may also find their way into the root canal system through dental materials and instruments that are used during the treatment. Some studies have suggested the necessity of decontamination of these materials and instruments prior to using. Also, the practice of changing gloves and disinfecting the tooth and rubber dam may help to reduce the possibility of introducing bacteria into the root canal space. This study is aimed to evaluate the success rate of initial root canal treatment using an enhanced sterility protocol.
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.
The prevention and control of post-treatment pain is of great importance for the comfort of the patient as well as for the clinician's prestige. In this study, the effect of 940 nm diode laser disinfection on the postoperative pain of retreatment cases was evaluated.
This Study Was Made to Evaluate the Antibacterial Effect of Different Antibacterial Combinations on Revascularization Process in Permanent Anterior Immature Teeth. Immature Necrotic Permanent Maxillary Incisors (n = 40) of Patients 8-18 Years Old Were Divided Into 4 Equal Groups (Each n = 10) According to the Intracanal Medicament: Group 1 Was Treated With Triple Antibiotic Paste (TAP), Group 2 Was Treated With Ciprofloxacin + Propolis Paste (CP), Group 3 Was Treated With Ciprofloxacin + Metronidazole Paste (CM), Group 4 Was Treated With Propolis + Metronidazole Paste (PM). Cases Were Followed at Regular Intervals up to 18 Months Clinically and Radiographically.
The aim of the present study is to assess with PA x-rays and CBCT scans the volumetric changes in periapical radiolucencies in endodontically treated teeth 1 year after endodontic treatment and evaluate how well the lateral canals are filled after irrigation with the new generation of negative irrigation pressure unit with and without the ultrasonic irrigation.
Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in multiple visits (MV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 24 months.
Sampling of accessed root canals with endodontic paper points during treatment and immediately pre-obturation of endodontic root canals was carried out.
The purpose of this randomized clinical trial was to evaluate the incidence of postoperative pain after retreatment using different techniques. Patients whom need retreatment were included. The presence of postoperative pain was assessed after retreatment cases at 1, 6, 12, 24 and 48 hrs.
