Evaluation of microleakage of RSA Roekoseal Automix root canal sealer
The sealing ability of RSA Roekoseal Automix root canal sealer using ThermaFil Plus and cold lateral condensation was compared to Roth's 801 root canal sealer. Fifty-two single canaled roots of extracted teeth were divided into four groups of twelve and instrumented to size 6 with .06 taper series …

Pain and root canal therapy: exploring their relationships within the DPBRN.
Introduction: Root canal therapy is a commonly employed and effective dental treatment often used to treat the symptom of intraoral pain. Unfortunately some patients experience severe amounts of pain post-operatively, but it is not clear why. Methods: Using a prospective observational study design …

Mutagenicity of root canal sealer RSA Roekoseal Automix in the Ames test
The mutagenic activities of the root canal sealers, RSA Roekoseal Automix and AHPIus, were tested in the bacterial gene mutation assay (Ames test). Both materials were tested immediately after mixing and after setting 24 h. The Salmonella typhimurium tester strains TA98 and TA 100 were used to …

Preventive endodontics in mature teeth: the importance of avoiding root canal treatment /
… observed due to negative effects of traditional root canal treatment, including changes in tooth structure, biomechanical behaviour and fracture resistance, advanced comprehension of dental pulp’s healing capabilities and introduction of hydraulic calcium silicate-based cements. Accurate …

Some factors involved in mechanical instrumentation in the root canal of a permanent tooth
Endodontics can best be defined in the words of the preface of the Bulletin on Endodontics prepared by the University of Toronto Dental School, This states that "endodontics is the union of two Greek words 'endo' within and 'odontos' a tooth. The English equivalent of these two Greek words …

Microbiological Study of Bacterial Load Reduction in the Root Canal System Utilizing a Novel ErYagLaser
… technique in reducing bacterial load in root canals. In this study, mandibular molars are prepared and cultured with Enterococcus faecalis, and experiment was perform to test whether laser-activated irrigation could significantly reduce bacteria in the root canal system. The teeth were …

Use of electromagnetic stimulation on an Enterococcus faecalis biofilm in root canal treated teeth in vitro
Introduction: Nonsurgical root canal therapy procedures aim to reduce the total microbial load within an infected root canal system through chemomechanical debridement of the root canal system via instrumentation in conjunction with an antibacterial irrigating solution. The most commonly used …

The Degradation of Resin Materials Bonded to Dentine in the Root Canal by the Activation of Matrix Metalloproteinases
… were obtained from human permanent single-rooted teeth and restored with the test cements. The test cements’ push-out bond strength was measured and statistically analysed after ageing the specimens in artificial saliva for one week and after nine months. The matrix metalloproteinases …

Evaluating The Impact Of Voxel Size On AI-Based Segmentation Accuracy For Pulp Chamber And Root Canal Detection: An In Vitro Study
… (AI)-based segmentation of pulp chambers and root canals, using high-resolution CBCT as the reference standard, and to assess the effect of tooth type on segmentation performance. Methods: An in vitro study design was used to assess AI-based segmentation across three voxel sizes (75 µm, 150 …

The effectiveness of prophylactic etodolac on post-endodontic pain
… patients requiring conventional root canal therapy consented to single blind oral administration of either 400 mg of etodolac, 600 mg of ibuprofen, or a placebo, prior to conventional root canal therapy. Pain evaluation was completed on a pain survey that consisted of visual …

Comparison of Treatment Methods for Chronic Periapical Inflammatory Diseases // Сравняване на методи за лечение на хронични периапикални възпалителни заболявания
… is the presence of microorganisms colonizing the root canal system. To achieve optimal results from endodontic treatment, bacterial populations in the root canal must be eliminated or at least significantly reduced to levels compatible with the healing process of periapical tissues. The endodontic …

Effect of the GentleWave System on dentin microhardness and sealer penetration: an in vitro study
… on dentin hardness and sealer penetration in root canal treatment, aiming to assess its potential advantages over conventional techniques. Conventional instrumentation can alter root canal anatomy, necessitating irrigation methods that minimize mechanical impact. The GW System, utilizing …
