Root canal preparation is one of the most important stages in root canal treatment. Nowadays, the use of Nickel-Titanium(Ni-Ti) rotary instrument systems for root canal expansion is becoming very popular. The force required to rotate the Ni-Ti file is defined as the torque force and is considered a parameter for the stress produced within the canal. Ni-Ti rotary instruments can be used with a wide speed scale between 150 rpm (rotary per minute) and 40,000 rpm in conventional endodontic engines. Low torque and speed values mean low pressure applied by the instruments in the root canal. With low forces and vibrations, motor noise is generally negligible, and the instruments can easily shape most root canals in a reasonable amount of time and with minimal mechanical stress (in medium-easy canals). The use of lower torque values has been shown to reduce cyclic fatigue of Ni-Ti rotary tools. With reduced cyclic fatigue, the risk of instrument breakage in complex root canal morphologies is minimized and complications that may occur during root canal treatment are reduced. However, with low torque and speed values, cutting efficiency decreases and the process time increases as the instrument advances in the canal and during possible treatment. Decreasing cutting efficiency may also result in the operator applying force to move through the canal. With the applied force, the friction resistance within the canal increases and the heat produced increases. For this reason, it is thought that the risk of post-operative pain may increase during or after the procedure. The aim of this study is to investigate the incidence of post-operative pain and procedure time using the visual analog scale (VAS) among groups where low torque and speed values were applied during the use of the Ni-Ti rotary instrument system.
The aim of this study is to assess the effect of V. nilotica extract solution versus 2.5% NaOCl on the intensity of postoperative pain and the amount of bacterial load reduction.
A total of 64 primary molars of 5-8 years old children will be randomly selected from Pediatric dental clinic at Faculty of Dentistry, Mansoura University. Children will have two bilateral carious primary molars indicated for pulpectomy ; One side will be treated in one visit and the other will be treated in two visits. Clinical and radiographic evaluation for 3 , 6, 12 months
clinically compare the intensity of post-operative pain and the amount of bacterial load reduction after using 20% Epigallocatechin-3-gallate solution during chemomechanical preparation, versus 2.5% NaOCl, in asymptomatic necrotic mandibular premolars treated in a single visit.
The aim of this study is to compare the effect of antimicrobial-corticosteroid mixture and cryotherapy as final root canal irrigating solutions on post-instrumentation pain in single-canal teeth with necrotic pulps.
Dental pulp necrosis is one of the most common pathological conditions that results in tooth loss. However, regeneration of functional dental pulp has proved difficult. Therefore, the investigators conduct a single-arm study to evaluate the efficacy and safety of pulp regeneration induced by SHED mixed with hyaluronic acid polymerization in patients with pulp necrosis of permanent teeth.
To compare the effect of N-acetylcysteine versus calcium hydroxide as intra canal medication on: - Intensity of postoperative pain. - Bacterial load reduction. - levels of MMP -9 in Periapical Fluids.
The aim of this prospective randomized clinical trial is to evaluate the effect of different apical size and taper preparation (35. 04; 35. 06; 45. 04 and 45. 06) on postoperative pain at 6, 12, 24, 48 and 72 hours, and intra-canal bacterial count in patients having mandibular premolars with necrotic pulps.
the aim of this study is to compare the effect of using Diclofenac Sodium Versus Calcium Hydroxide as Intracanal medication on intensity of postoperative pain, bacterial load reduction after root canal preparation and periapical matrix metalloproteinase 9 level (MMP-9) post-instrumentation and pre-obturation in teeth with necrotic pulp
