Introduction: Contamination of etched enamel to saliva before placement of sealant prevents the appropriate bonding and results in microleakage. Using bondings is effective for decreasing the microleakage. This experimental study aimed to evaluate the effect of bonding agent on microleakage of a fissure sealant before or after contamination to saliva. Methods: In this experimental study 40 sou...
Background and Aims: As in fissure sealant therapy the tooth surface is mostly enamel, the use of an enamel bonding agent (hydrophobic bonding agent) may be more cost effective than that of newer generations of bonding (hydrophilic bonding agents). The aim of this study was to compare the retention and durability of fissure sealant therapy when applying an enamel bonding agent, a dentin bondi...
Coloboma is a congenital disease that contributes significantly to childhood blindness. It results from the failure in closing the optic fissure, a transient opening on the ventral side of the developing eye. Although human and mouse genetic studies have identified a number of genes associated with coloboma, the detailed cellular mechanisms underlying the optic fissure closure and coloboma form...
BACKGROUND AND OBJECTIVES Fluoride is being used for the prevention of dental caries since a long time. Incorporation of fluoride in pit and fissure sealants has been found to reduce initiation and progression of pit and fissure caries. Authors conducted this study to evaluate and compare the effect of fluoride releasing pit and fissure sealants on the inhibition of demineralization of adjacent...
Background: Nipple fissure is one of the most common diseases in breastfeeding which leads to maternal pain and disruption of the mother-infant relationship. Since the most important consequence of nipple fissure is the deprivation of the infant from breast milk, it is very important to prevent and treat this condition. The aim of this study was to investigate the effect of the topical form of ...
Background & Aim: Conjunctivitis is caused by a large group of infectious and non-infectious factors. However, no evidence of conjunctivitis following anal fissure surgery has been reported and such cases are not common. The present study is to report three cases of uncommon conjunctivitis following anal fissure surgery. Cases: Patients presented in this study included three middle-aged women ...
OBJECTIVES The morphology and anatomical relationship of periorbital features vary according to age, sex and ethnicity. Standard database regarding periorbital region is available for other ethnic groups. Since there is no data available in the literature, specifically for south Indian ethnic adults, the present study was carried out to determine the normal average values for South Indian ethni...
To determine the normal appearance of the flax and interhemispheric fissure, 200 consecutive normal CT scans were evaluated prospectively. On unenhanced scans, the normal falx is visualized in 90% of patients and therefore interhemispheric hyperdensity alone should not be considered a sign of subarachnoid hemorrhage. The flax is most often (88%) visualized in the posterior part of the interhemi...
Purpose Basement membrane degradation and macrophage aggregation at the optic fissure margins are crucial to optic fissure closure during normal murine eye development. Basement membrane degradation is also an essential step in cancer development, and matrix metalloproteinases (MMPs) play an important role. In this study, we investigated MMP alteration at the degrading basement membrane of opti...
