Background: There are a lot of techniques to obturate the root canals, but lateral condensation of gutta-percha is the most used one. An important aspect of thermafil is the error margin tolerated by the manufacturer in the production of plastic carriers. In literature, there is no evidence about discrepancy percentage between different carriers. It is demonstrated that the error margin of gutta-percha is 0.5% and is 0.2% for metal files (ISO standards). Objective: The aim of this study was to evaluate the real dimensions of thermafil plastic carriers observed by the stereo microscope measuring the dimensional discrepancy between them...

Obturator hernia (OH) is a rare condition that accounts for 0.073-1% of abdominal hernias and 0.48% of bowel obstructions. OH frequently occurs in elderly women, with an incidence that increases with age. The only treatment for OH is surgical intervention, and the approaches used vary greatly. Consequently, a well-defined consensus has not yet emerged. We assessed the efficiency and safety of the midline extraperitoneal approach for OH. Six patients with OH repaired using the midline extraperitoneal approach at KKR Sapporo Medical Center between April 2011 and January 2016 were included in the study...

BACKGROUND: Palatomaxillary defects were historically restored with a prosthetic obturator; however, advances in local and free tissue transfer has provided a viable alternative for appropriately selected patients with palatomaxillary defects. METHODS: A retrospective chart review of patients who underwent palatomaxillary reconstruction by the lead author between 1998 and 2016 was conducted. Patients who were restored with a palatal obturator were excluded. RESULTS: One hundred forty patients were reconstructed with a total of 159 local, regional, and free flaps with a 96...

Reciprocal inhibition of motor neurons via Ia inhibitory interneurons recruited by stimulation of proprioceptive afferents supplying antagonist muscles has been well described. Changes in the efficacy of inhibition, and sometimes even a switch from inhibition to facilitation, have been reported in the literature after disruption of descending pathways. We sought to test whether such facilitation could be expressed in normal animals by evaluating the presence of facilitation in acute preparations from uninjured animals...

INTRODUCTION: In total hip arthroplasty via a direct anterior approach, the femur must be elevated at the time of femoral implant placement. For adequate elevation, division of the posterior soft tissues is necessary. However, if we damage and separate the posterior muscle tissue, we lose the benefits of the intermuscular approach. Furthermore, damage to the posterior soft tissue can result in posterior dislocation. We investigate that protecting the posterior soft tissue increases the joint stability in the early postoperative period and results in a lower dislocation rate...

Background: The evaluation of chronic pelvic and perineal pain (CPP) is often complex. The patient's description of the pain often appears to be disproportionate to the limited findings on physical examination and/or complementary investigations. The concept of central sensitization may allow better understanding and management of patients with CPP. Objective: The aim of this study was to elaborate a clinical evaluation tool designed to simply identify sensitization in pelvic pain...

We report a 65-year-old male with histopathologically proven prostate cancer and multiple pelvic node metastases using a robotic-assisted radical prostatectomy procedure plus extended pelvic lymph node dissection. Positron emission tomography (PET) scan findings demonstrated a moderate accumulation of11 C-choline in a metastatic left obturator node sized 8 × 8 mm, though only a faint uptake of fluorodeoxyglucose (FDG) was noted.11 C-choline PET/computed tomography (CT) may be useful for the diagnosis of a tiny metastatic lymph node not demonstrated by CT, magnetic resonance imaging, or FDG-PET/CT and to determine the need for an extended pelvic lymph node dissection...

BACKGROUND: The article describes the results of research on efficiency of using antimicrobial photodynamic therapy in treatment of chronic periodontitis. METHODS: 88 root canals in 84 patients were examined and treated. The diagnosis of chronic apical periodontitis was made based on anamnesis, data of clinical and instrumental examination, assessment of X-ray images. Patients were randomly selected to comply with the purity of the experiment. RESULTS: It was found that the use of antimicrobial photodynamic therapy leads to a reduction of medical cases accompanied by pain reaction after a one-stage treatment of chronic periodontitis when compared with data of the patients treated with calcium hydroxide preparation...

PURPOSE: To establish whether bipolar transurethral resection of tumours (bTURB) on the lateral bladder wall is superior to monopolar transurethral resection (mTURB) of such tumours. To our knowledge, this is the first prospective randomised study, which defines complete resection depending on obturator jerk as primary endpoint. METHODS: In a prospective, randomised, single centre study, 52 patients with newly diagnosed or recurrent bladder tumour on the lateral bladder wall were enrolled and randomised to undergo mTURB or bTURB; 44 patients were eligible for analysis, of whom 21 underwent mTURB and 23 bTURB...
