Objectives The purpose of this study was to present a case of regenerative endodontic procedure. Case The maxillary 1st premolar of a 9-year-old patient was diagnosed as necrotic. Since the tooth was immature, we decided to treat this tooth with regenerative endodontic procedure. After disinfection of the canal, bleeding was induced by lacerating the peri-apical tissues ...

BACKGROUND The key to success of any root canal therapy is adequate obturation of the prepared root canal space. Root canal sealers are not dimensionally stable and might dissolve partially over a period of time. The objective of this in vitro study is to evaluate the push-out bond strength to intraradicular dentin of two endodontic obturation materials. MATERIAL AND METHODS Forty extracted s...

Adaptation and placement of alpha-phase gutta-percha delivered with a plastic core-carrier, Thermafil, was compared to the lateral condensation of gutta-percha in a specific tooth model. Fifty-one mandibular molar roots with separate canals, patent canal orifices and curvatures greater than 15 degrees were cleaned and shaped with K-files and 2.5% sodium hypochlorite to a size 30 at the apex, an...

PURPOSE To examine the anatomical variation of normal human collector channel orifices and their relationship with Schlemm's canal. METHODS Ten human anterior segments fixed by immersion or perfusion were dissected radially and further divided by fine dissection into corresponding inner and outer wall segments. The tissues were dehydrated, critical-point dried, sputter coated, and examined by...

OBJECTIVES The purpose of this study was to design a software program to estimate the curved root canal working length by using curved line software and comparing its accuracy with Trophy and Cygnus software programs. METHODS 120 simulated curved canals were divided into 12 groups based on the radius and the angle of the curvature. The true canal length was measured from the orifice to the te...

Objective: To determine whether the missing canals in endodontically treated single-rooted teeth with two-canals are present either buccal or lingual/palatal for Turkish subpopulation. Methods: High-quality cone-beam computed tomography scans of 1297 belonging to 782 adults over age 18 were obtained from archive a dental clinic. Within this dataset, 129 had undergone endodontic treatment and po...

Background: The natural orifice transluminal endoscopic surgery (NOTES) has become a commonly considered novel approach in the surgical field. The NOTES provide possibility of operation through the natural orifice and decreases the intentional puncture of the systemic organ and subsequent complications. Totally transanal laparo-endoscopic single-site proctoColectomy-Ileoanal J-Pouch (TLPC-J) is...

The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any other root. An inability to detect and treat a second mesiobuccal canal (MB2) is a reason for endodontic failure in maxillary first molars (1). Modifications in endodontic access and detection techniques, along with advancements in illumination and magnification technology, have aid...

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...
