Filter by:Regenerative endodontic procedures are intended to replace damaged tooth structures, including dentine and root structures, in addition to cells of the pulp-dentine complex. This treatment modality have been tested on immature necrotic teeth because they are anticipated to have a greater chance of pulp tissue regeneration. However, it has been recently suggested for treating fully formed mature necrotic permanent teeth with closed apices since the conventional root canal treatment yielded many drawbacks. A number of studies have evaluated the regeneration outcomes of using blood clot as a scaffold. However, there are limited studies in the literature on using other scaffolds such as platelet-rich fibrin (PRF). This clinical study will evaluate clinically and radiographically the effectiveness of PRF versus induced bleeding in treating mature necrotic teeth. Fifty patients with necrotic mature teeth with periapical lesions will be invited to participate in this study. Teeth will be treated using calcium hydroxide as intracanal medicament then using PRF (n=25) and blood clot (n=25) as scaffold. All teeth will be sealed coronally using NeoMTA Plus™. Treated teeth will be assessed clinically and radiographically using 2D periapical radiographs. The reported clinical and radiographic outcomes will be compared using SPSS.
This is a Humanitarian Device Exemption (HDE) approved device. The purpose of this study is to evaluate the continued safety and probable benefit of the restor3d Total Talus Replacement device in commercial use.

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 goal of this clinical trial is to compare the post operative pain after using three different instrumentation techniques in pulpectomy treatment of pediatric participant. The main question it aims to answer: If different instrumentation techniques will affect the post operative pain in pulpectomy treatment of primary molars ? Participants will evaluate the pain using Modified Wong baker pain rating scale. Researchers will compare [ the adaptive XP endo shaper, Fanta AF baby files, and hand K files] to see if they will affect the post operative pain.
The goal of this observational study is to compare the presentation, treatment, and outcomes in patients suffering traumatic pancreatic injuries from blunt or penetrating trauma. The questions this study aims to answer are: 1. Does a statistically significant association exist between pancreatic injury grade and the following individual factors: - Mortality - Morbidity - Injury severity score 2. Is there an association between post-operative pancreatic complications and operation-specific intervention? 3. Does pancreatic injury score correlate with certain intra-abdominal organ injuries? Participants meeting criteria are greater than 18 years old, with no history of pancreatic surgery who were hospitalized at Kern Medical Center after presenting to the institution's emergency department as tier 1 or 2 trauma activations following blunt or penetrating abdominal injury and were diagnosed with pancreatic injury during the same hospitalization.
This study was performed to compare endodontic regeneration outcome in necrotic mature single rooted teeth with periapical radiolucency using platelet rich fibrin (PRF) & concentrated growth factor (CGF) as a different natural scaffold by evaluation of: - Regaining pulp sensibility by thermal test (hot and cold) - Periapical healing using digital radiography and selected samples will be evaluated using Cone Beam Computed Tomography (CBCT).
Acute pancreatitis is one of the most common gastrointestinal disorders requiring hospitalization worldwide. Pancreatic fluid collections can occur as a consequence of acute and chronic pancreatitis and can result in significant morbidity and mortality, including significant abdominal pain, gastric outlet obstruction, biliary obstruction, organ failure, persistent unwellness, infection and sepsis. Symptomatic pancreatic fluid collections require treatment, and endoscopic drainage is considered standard of care. The aim of this study is to evaluate the treatment outcomes in patients undergoing standard of care, endoscopic treatment of pancreatic fluid collections.
Laser Ablation therapy (LA) using an 810nm diode laser and Indocyanine Green (ICG) solution, which efficiently absorbs laser energy and increases the effectiveness of tissue removal. Intracanal heating can potentially cause damage to structures outside the tooth root. The study was to observe possible changes in the periodontal ligament and cementum resulting outside the root using this treatment. Histological and morphological examination of extracted cementum, ligament, and collagen post-exposure showed no difference in these structures vs. non-treated controls.
Forty cases of necrotic primary molars in children aged 4-8 years were selected to compare the effect of manual versus rotary pulpectomy regarding parental acceptance and obturation quality.
