AN ANAL FISSURE is ai1 ulcer of t h e a n a l canal which may extend from the anal verge to the dentate line. It is usually exquisitely painful, so the best treatment is that which is the most expedient but also provides negli#ble recurrence and minimal disability of anal function. Lateral subcutaneous internal anal sphincterotomy best fulfills these criteria and we strongly recommend it as the...

The unusual sensitivity and attraction to auditory stimuli in people with Williams syndrome (WS) has been hypothesized to be the consequence of atypical development of brain regions surrounding the Sylvian fissure. Planum temporale surface area, which is determined in part by Sylvian fissure patterning, was examined in 42 WS and 40 control participants to determine if anomalous Sylvian fissure ...

objective: considering the fact that several bonding agents are available in market, clinical evaluations are required to find the durability of the sealants after using bonding agents. the purpose of this study was to compare the durability of the fissure sealant after applying two kinds of dentin bonding materials, adhese and excite. materials and methods: in this clinical study sample group ...

STATEMENT OF THE PROBLEM The purpose of placing sealants is to inhibit caries by physical closure of the pits and fissures of teeth. A device named DIAGNOdent is useful in detecting occlusal caries by employing laser fluorescence (LF). However, there are contradictory results in the influence of sealants on LF measurements. PURPOSE The aim of this study is to investigate the effects of two di...

background: marginal seal has a principal role in durability and clinical success offissure 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 ofthe following five groups: group 1: acid-etching (ultra-etch) + fissure sealant (conv...

OBJECTIVES To investigate the evidence for sealants as a means to prevent caries in children and adolescents and, in the presence of suitable supporting evidence, to develop a protocol for the application of sealants. METHODS Previous systematic reviews on this topic were used as the basis for the current review. Ovid MEDLINE, CINAHL and several other relevant bibliographic databases were sea...

BACKGROUND This article presents evidence-based clinical recommendations for use of pit-and-fissure sealants developed by an expert panel convened by the American Dental Association Council on Scientific Affairs. The panel addressed the following clinical questions: Under what circumstances should sealants be placed to prevent caries? Does placing sealants over early (noncavitated) lesions prev...
