Early pregnancy ultrasound must satisfy objective criteria to make a safe diagnosis of miscarriage. The differential low-lying gestational sac includes cervical stage miscarriage and caesarean scar ectopic pregnancies. Misdiagnosis can lead significant maternal morbidity. We describe in 36-year-old primiparous woman where findings gestation satisfied for miscarriage; however, dilatation curetta...

BACKGROUND Due to the scarcity of exfoliated/extracted human primary teeth with complete roots, artificial teeth were developed as an alternative to be used for educational and laboratory research purposes. This study aimed to assess the feasibility of using artificial primary teeth for conducting laboratory research through an experiment related to canal length determination, comparing artific...

Large-scale longitudinal epidemiological studies, such as the Study of Health in Pomerania (SHIP), investigate thousands of individuals with common characteristics or experiences (a cohort) including a multitude of sociodemographic and biological factors. Unique for SHIP is the inclusion of medical image data acquired via an extensive whole-body MRI protocol. Based on this data, we study the va...

The extraction of impacted mandibular third molars has long been associated with the dreaded and rarely, grave and irreversible complications. The oral and maxillofacial surgeons’ dogma strongly links most complications with the proximity of inferior alveolar canal and the impacted teeth, the relationship of which is still a topic of debate among surgeons. In this randomized, prospective case s...

BACKGROUND There are various microorganisms related to intra and extra-radicular infections and many of these are involved in persistent infections. Bacterial elimination from the root canal is achieved by means of the mechanical action of instruments and irrigation as well as the antibacterial effects of the irrigating solutions. Enterococcus faecalis can frequently be isolated from root canal...

Superior canal dehiscence syndrome, or Minor’s syndrome, is a recently described disease that results from the absence of bone over the superior semicircular canal which results in the communication between the perilymphatic space of the canal and the intra-cranial space. It is characterized by a wide range of symptoms involving imbalance, hearing loss or both. Symptoms may include strange perc...

Anatomic variations are common in human dentition. A clear understanding of these variations is very important for success of endodontic treatment. A dentist should be aware of these anatomic variations as this can affect the treatment outcome. A case of endodontic therapy is presented in which inability to locate an anatomically rare supplemental canal of a three rooted mandibular first molar ...

Background and Aim: Knowledge about the root canal system variations is crucial for successful endodontic treatment. This study aimed to examine the applicability of cone-beam computed tomography (CBCT) as a substitute for the gold-standard tooth clearing technique in identification of internal anatomical variations of mandibular incisors. Materials and Methods: This in-vitro study evaluated 6...

BACHGROUND Peritonitis and exit site (ES) infection are two main complications of peritoneal dialysis. There are some controversies regard to preventive strategies for ES care. In this study we compared peritonitis and ES infection rates in patients with and without dressing. MATERIALS AND METHODS This historical cohort study carried out on 72 patients under continuous ambulatory peritoneal d...

INTRODUCTION This study was performed to observe the efficacy of a modified surgical wound dressing applied as part of decannulation wound care after tracheotomy. METHODS Eighty-four patients were randomly allocated into a traditional care group, a surgical wound dressing group, and a modified surgical wound dressing group. Each group comprised 28 patients. The following outcomes were observe...
