AIM To compare systematically the sealing ability provided by four endodontic cements: AH Plus, Pulp Canal Sealer EWT, RoekoSeal and GuttaFlow. METHODOLOGY A sample of 100 human mandibular incisors with oval-shaped canals was selected from an initial sampling of two hundred teeth. The root canals in 80 teeth were prepared and filled by the same operator using the cold lateral compaction techn...

AIM To two- and three-dimensionally assess the fit of the first K-file binding at working length after a crown-down canal procedure. METHODOLOGY Twelve maxillary molars with fully developed roots and four separate root canals were selected. Canals were pre-flared using ProFile 0.04 instruments to three quarters of estimated working length (WL). WL was electronically determined using an ISO 06...

The normal and lateral line cycloid scales of a cyprinid fish Rutilus frisii kutum Kamenskii, 1901 have been subjected to scanning electron microscopy technique to study their detailed structure. The scales have the general morphological characteristics of the cycloid scales. In the normal scale located below the dorsal fin, the focus lies on the anterior region with few mucous pores. There is ...

Article History The present paper deals with a new species of the genus Phyllodistomum [2].Viz Phyllodistomum triangulata n.sp is reported from freshwater fish Mastacembelus armatus (L.) Jayakwadi dam, Dist Aurangabad. It differs from all the earlier reported species in having the body of the fluke is dorso-ventrally flattened, anterior portion of the body is long and narrow while the posterior...

OBJECTIVE The purposes of this retrospective study were to represent a newly designed theoretical model for determining orifice shape and morphologic properties of mandibular premolars and to correlate these findings with each other. MATERIALS AND METHODS A total of 287 mandibular premolar images obtained from 88 patients by cone-beam computed tomography were included in this study. The measu...

INTRODUCTION Oval-shaped canals represent a challenge for rotary nickel-titanium (NiTi) files because buccal and/or lingual recesses are commonly left uninstrumented. The aim of the present study was to evaluate the debridement quality of the Self-Adjusting File (SAF) system in oval canals and compare it with the debridement achieved by a commonly used NiTi rotary system. METHODS A careful sp...

BACKGROUND AND AIMS The purpose of this study was to compare several parameters of root canal preparation using two different rotary Nickel-Titanium instruments: Pro-Taper (Dentsply Maillefer, Ballagigues, Switzerland) and Hero-Shaper (Micro Mega, Besancon, France). METHODS Twelve extracted maxillary premolars were randomly divided into two groups and embedded into a muffle system. All root c...

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...
