Inguinal bladder hernia is a rare clinical condition, with 1-3% of all inguinal hernias involving the bladder. Any portion of the bladder may herniate, from a small portion or a diverticulum to most of the bladder. We present a 55-year-old male with an intermittent right scrotal mass of 6 months' duration. The mass lesion protruded through the right inguinal canal before voiding and reduced aft...

Objective. Determination of the effect of dentin bonding agent (DBA) on the prevention of tooth discoloration produced by mineral trioxide aggregate (MTA). Methods. 50 teeth were endodontically treated and after removal of 3 mm of obturating materials were divided into five groups. In white MTA (WMTA) and grey MTA (GMTA) groups, these materials were placed in root canal below the orifice. In DB...

Background. The aim of this study was to compare the push-out bond strengths of calcium silicate-based ProRoot MTA and Biodentine cements and SureFil SDR and EverX Posterior bulk-fill composite resins. Methods. Twenty-four single-rooted maxillary central incisors were sectioned below the cementoenamel junction, and the root canals were instrumented using rotary files. Thereafter, a parallel pos...

OBJECTIVE To compare the efficacy of gutta-percha removal achieved with simple mechanical technique using two different solvents. MATERIALS AND METHODS It was an in vitro experimental study conducted at the Aga Khan University Hospital, Karachi, Pakistan on 27 extracted human molars divided into two groups by alternate sampling technique. The teeth were prepared by manual filing and obturated...

Complexities in obturation and difficulties disinfection are the major problems that make endodontic treatment very time-consuming. A new perspective is needed to reduce working time as well answer these two problems. Until now, none of established techniques for root canal filling can guarantee a perfect seal. Solid substances cannot be manipulated easily fill tiny branches system herme...

The most commonly used flowmeter is the orifice meter. The orifice meter consists of two parts. As shown in Figure 1, they are the measurement orifice plate, which is installed in the process line, and the differential pressure transmitter, which measures the pressure developed across the orifice plate. There has been extensive research to determine the operating characteristics of orifice meters.

IMPORTANCE Improvements in endoscopic technology and reconstructive techniques have made the endoscopic endonasal approach (EEA) a viable option to approach ventromedial lesions in the region of the hypoglossal canal. Prior to contemplating this surgical corridor, a thorough understanding of anatomic relationships and landmarks is essential to safely approach this region of the posterior skull ...

one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...

On the basis of dissections of 32 temporal bones of the guinea pig, measurements were taken of selected size parameters of the temporal bone. The measurements performed included external and internal size parameters of the bone. Among these were the following: the length, width and height of the external and internal auditory meatus, the length of the incudomallear complex, the height of the at...

In two stages of total ear reconstruction surgery for children with microtia and atresia, plastic surgeons and otologists have cooperated to reduce the number of surgeries and to achieve both esthetically and functionally better results. Ear elevation, external canal plasty and tympanoplasty are performed cooperatively in the second stage of surgery. In the past 5 years we have experienced 70 c...
