This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA ( n = 188), PCEM 194), RCT 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale PIs until day 7 recorded. Patients’ demographic...
Transient osteoporosis during pregnancy is a rare, self-limiting disease. We report on 36-year-old woman who had bilateral subcapital femoral neck fractures the 6th month of pregnancy. The diagnosis was made 4 days after delivery, because radiography declined by patient for fear radiation. Fixation not feasible owing to bone resorption, and 2-stage bipolar hemiarthroplasty therefore performed. Magnetic resonance imaging best non-invasive investigative tool pregnant women with hip pain. Early...
In engineering and agriculture, morphological properties are the important characters in studying physical of products. The use image processing machine vision technique to measure appearance objects has become very common recent years. purpose this study was predict diameters, area perimeter spherical using nonlinear multivariate modeling. hardware part system included an imaging station, a back lighting source, camera, frame grabber personal computer. distance from camera considered...
The purpose of this study was to compare apical microleakage following canal obturation with lateral and thermoplasticized gutta-percha compaction techniques.Ninety extracted single-rooted maxillary teeth were used in study. Seventy randomly divided into two groups: One group obturated by technique the other Obtura II (thermoplasticized technique); 5 positive controls (without obturation) negative (with each group. specimens placed India ink for 48 h then halves. amount dye...
One of the most important features cardiac that are associated with several cardiovascular risk factors such as myocardial ischemia, coronary artery stenosis, metabolic syndrome, atrial fibrillation, and others, epicardial pericardial visceral adipose tissues around cardiac. Therefore, automatic detection, quantification, segmentation fats can be used an additional feature for medical imaging visualization in clinical routine order to save time a reliable tool assessment. In this paper, we...
The aim of the present study was to evaluate biocompatibility two modified formulations Portland cement (PC) mixed with either titanium oxide or both and calcium chloride.Polyethylene tubes were filled PCs Angelus MTA as control; then implanted in 28 Wistar rats subcutaneously. One tube left empty a negative control each rat. Histologic samples taken after 7, 15, 30 60 days. Sections assessed histologically for inflammatory responses presence fibrous capsule granulation tissue formation....
Heart mediastinal and epicardial fat tissues are related to several adverse metabolic effects cardiovascular risk factors, especially coronary artery disease (CAD). The manual segmentation of those fats is that the high dependence on user intervention time-consuming analyzes. As a result, automated measurement cardiac could be considered as one most important biomarkers for risks in imaging medical visualization by physicians. In this paper, we validate an automatic approach non-contrast CT...
The anatomy of the root canal system always affects endodontic treatment outcomes. Mandibular premolar teeth demonstrate extreme variations in morphology. first premolars typically exhibit basic single-root and single-canal anatomy. occurrence three roots mandibular has not been commonly reported literature. This article a case 26-year-old male with spontaneous pain representing presence an extra on periapical radiograph. Cone-beam computed tomography (CBCT) was used to assess details which...
Epicardial and Pericardial visceral adipose tissues around the cardiac are associated with several cardiovascular risk factors adverse metabolic effects. As a result, automatic recognition determination of fats can be used as an additional feature in medical imaging visualization by physicians, due to advanced technologies that offer significant amount information high accuracy. The CT images also requires image segmentation methods. In this paper, we propose automated method for epicardial...
Practitioners need to know the normal and complex anatomy of root canal system individual teeth. Maxillary central incisors almost in all cases have one system. This case report describes a non-surgical endodontic treatment double-rooted maxillary incisor using cone-beam computed tomography (CBCT). A fourteen-year-old male with spontaneous pain left showed presence an extra on periapical radiograph. CBCT was used assess details that lead finding narrow mesial main root. Also, bone defect...
Pulp canal calcification (PCC) is common in patients with dentinogenesis imperfecta (DGI). We present endodontic management of multiple anterior and posterior teeth PCCs a patient DGI type II using guided endodontics. A 26-year-old female was diagnosed II. Clinical examination revealed palatal cusp fracture tooth #13, microcracks #14, sinus tract the maxillary right buccal vestibule related to #13. Periapical radiographs all teeth, periapical radiolucencies several teeth. Due difficult...
This study aimed to compare the changes in root canal anatomy following use of PathFile and R-Pilot using cone-beam computed tomography (CBCT).In this vitro, experimental study, 60 extracted maxillary first second molars with 20 40° mesiobuccal curvature, minimum 19 mm length, no calcified canals history previous treatment were divided into two groups (n=30). CBCT scans taken before after treatment, sections at 1, 2 3 from apex compared. Pairwise comparisons carried out Mann Whitney-U test....
