Customized glass fiber posts that is well adjusted into the root canal and have mechanical properties similar to those of dentin may be a suitable treatment for severely compromised endodontically treated teeth. This article reports a 3-year follow up of severely damaged endodontically treated teeth restored with unidirectional fiber glass customized post and core system instead of a convention...

This study was done to compare the pre and post-operative hearing results in patients undergoing canal wall down mastoidectomy with classical type III tympanoplasty using temporalis fascia alone. Patients of >or=5 years age with the diagnosis of Chronic otitis media (squamous) with conductive or mixed hearing loss, needing canal wall down mastoidectomy and with intact and mobile stapes suprastr...

PURPOSE Post surface conditioning is necessary to expose the glass fibers to enable bonding between fiber post and resin cement. The purpose of the present study was to evaluate the effect of different surface conditioning on tensile bond strength (TBS) of a glass fiber reinforced post to resin cement. MATERIALS AND METHODS In this in vitro study, 40 extracted single canal central incisors we...

AIM To evaluate the apical microleakage of Thermafil obturations after three different post space preparation techniques. MATERIALS AND METHODS 33 root canals of mono-radiculated extracted teeth were prepared with M two and then obturated with Thermafil. Teeth so treated were then divided into three groups and the post space to middle root was prepared using three different techniques. In sam...

BACKGROUND A few studies have investigated the effect of the activation mode of adhesive systems on bond strength of fiber posts to root canal dentin. This study investigated the push-out bond strengths of a glass fiber post to different root canal regions with the use of two adhesives with light- and dual-cure polymerization modes. MATERIALS AND METHODS In this in vitro study, 40 maxillary c...

INTRODUCTION An overlooked but important part of successful root canal treatment is a straight-line access (SLA). The purpose of this in vitro study was to compare the efficacy of IntroFile and PreRaCe rotary instruments with Gates Glidden (GG) drills in gaining SLA by cone-beam computed tomography (CBCT). METHODS AND MATERIALS A total of forty five extracted mandibular first molars were sele...

BACKGROUND/AIMS We investigated which dialysis unit blood pressure (BP) is the most useful for predicting home BP in patients undergoing hemodialysis (HD). METHODS Patients undergoing HD who had been treated > 3 months were included in this study. Exclusion criteria were hospitalized patients with acute illness and changes in dry weight and anti-hypertensive drugs 2 weeks before the study. We...

Introduction Following a burst fracture, decompressive surgery is often recommended on the basis of imaging alone. There is, however, little evidence that the removal of intra-canal bone fragments is of neurological benefit to the patient (1). Further, there is doubt as to whether the fragment position seen on post-injury CT scans represents the true extent of the occlusion produced during the ...

THE pressure relationships in the anterior chamber, the canal of Schlemm, and the episcleral venous plexus are of obvious importance to the understanding of the drainage of aqueous humour. Episcleral venous pressures have been estimated by several workers (Thomassen, 1947 ; Linner, 1954 ; Bain, 1954), but so far no direct measurements of the pressure in the canal of Schlemm have been attempted....
