background and aims. marginal seal of the material is extremely important in fissure sealant therapy. the aim of this study was to investigate microleakage of flowable composite resins and conventional fissure sealants with or without dentin bonding agent. materials and methods. the occlusal surface of 60 intact extracted human premolars, divided into four groups, were cleaned with pumice/slurr...

Objective To validate the computer-assisted method of measuring palpebral fissure length and philtrum smoothness using digital patient photographs. These are key diagnostic facial features of Fetal Alcohol Syndrome. Design Prospective study. Setting Motherisk Program (including Breaking the Cycle), Hospital for Sick Children, Toronto a clinical, research and teaching program dedicated to antena...

Ocular coloboma is a congenital defect resulting from failure of normal closure of the optic fissure during embryonic eye development. This birth defect causes childhood blindness worldwide, yet the genetic etiology is poorly understood. Here, we identified a novel homozygous mutation in the SALL2 gene in members of a consanguineous family affected with non-syndromic ocular coloboma variably af...

BACKGROUND Various options are available for treatment of chronic anal fissure, each with its own associated complications. This study aimed to evaluate the efficacy of topical Glyceryl Trinitrate (GTN) for anal fissures in an outpatient setting. METHODS A prospective experimental study was carried out at the outpatient department of Surgical Unit IV, Liaquat University Hospital from Aug 2004...

This paper introduces a novel approach to analyze Yakovlevian torque by quantifying the bending of human brain interhemispheric fissure in three-dimensional magnetic resonance imaging. It extracts the longitudinal medial surface between the cerebral hemispheres, which are segmented with an accurate and completely automatic technique, as the shape representation of the interhemispheric fissure. ...

becoming available, as well as results from long-term clinical trials, a great deal of evidence has accumulated to support the clinical efficacy of pit and fissure sealants. Since smooth surfaces benefit most, and occlusal surfaces the least from the use of fluorides, an alternative technique which prevents occlusal caries can make a major impact on overall caries reduction when used in conjunc...

PURPOSE The purpose of this study was to evaluate the effect of material characteristics, preparation techniques, and fissure morphology on the microleakage and penetrability of pit and fissure sealants. METHODS Sealants used in the study included: (1) Aegis; (2) Conseal f; (3) Admira Seal; (4) Triage; and (5) Delton Opaque. A total of 100 extracted permanent molars were randomly assigned to ...

Introduction:The human lungs are divided by fissures into lobes, which facilitate movements of lobes in relation to one another. Anatomical variations of lungs including number, fissures and lobes are at utmost important. Aim: The study was done to note the morphological variation of the fissures and lobes in fetal lungs. Materials and Methods:62 human fetusesfrom 12 weeks to 40 weeks of gestat...

BACKGROUND Marginal seal has a principal role in durability and clinical success of fissure sealants. The aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. METHODS The 55 extracted premolars were assigned randomly to one of the following five groups: Group 1: Acid-etching (ultra-etch) + fissure sealant (co...

TITLE Antibacterial properties of fluoride releasing glass Ionomer cements (GICs) and pit and fissure sealants on Streptococcus mutans. BACKGROUND Occlusal pit and fissures are the most susceptible sites for dental caries. The clinical effectiveness of GICs and fissure sealants in preventing caries is well-documented, but there is some concern about bacteria left beneath sealants. OBJECTIVE...
