Clinical and Laboratory Evaluation of the Physical Properties of Two Light Cured Fissure Sealants
ثبت نشده
چکیده
Materials and methods: Helioseal and Delton Opaque fissure sealants were applied to pairs of contralateral mandibular second premolar teeth. Optically clear epoxy resin replicas were produced which were sequentially located and mounted within a defined plane. The replicas were transilluminated from below with diffused light, examined with a microscope and digital images captured. This allowed the entire fissure sealant peripheral border to be clearly identified and mapped. Categorized mapped areas were measured.

Abstract Background and Aim: Considering that 67 to 90 percent of dental caries in the age of 5 to 17are related to occlusal surface on molars,the use of fissure sealant has been reported as effective in reducing caries. The aim of this study was to assess the clinical effectiveness of fissure sealants placed on permanent first molars between 2016 and 2018 in pediatric department of Dental Facu...

Introduction: Sealing pits and fissures was introduced as an approach to prevent occlusal caries for more than two decades. The aim of this study was to compare the microleakage of flow able resin reinforced glass ionomer (Ionoseal) with other materials used as fissure sealants. Methods: In this in vitro study, 50 premolar teeth of human free of any caries were selected. Fissurotomy was done...

Background and Aim: Novel dental materials including nanocomposites have been introduced in recent years. It is claimed that they have superior properties such as high esthetic, low wear, increased filler content resulting in better mechanical properties, and releasing ions i.e. fluoride and amorphous calcium phosphate that are important for enamel remineralization. Considering these features, ...

OBJECTIVE This clinical study compared the retention rates of a nanofilled occlusal fissure sealant placed with the use of an etch-and-rinse or a self-etch adhesive over 24 months. METHODS Two-hundred and forty-four sealants were placed on the permanent premolars and molars of 16 subjects who had no restorations or sealants present on the fissures and no detectable caries. The sealants were p...
متن کاملComparative evaluation for microleakage between Fuji-VII glass ionomer cement and light-cured unfilled resin: a combined in vivo in vitro study.
Glass ionomer cement, besides being used as restorative material, can also be used as pit and fissure sealant. The use of glass ionomer cement as pit and fissure sealant has added benefit by its fluoride-releasing property that results in increased resistance of the fissures to demineralize. The capacity of a sealant to prevent microleakage into the fissure is important, since microleakage may ...
