Comparison between two glass-ionomer sealants placed using finger pressure (ART approach) and a ball burnisher.

Purpose: To compare in vitro marginal leakage and fissure penetration depth of sealants placed under finger pressure (ART) and a ball burnisher.

Methods: High-viscosity glass-ionomer hand-mixed Fuji IX GP and encapsulated Fuji IX GP Fast were used to seal 72 patent occlusal pits and fissures according to the ART approach or with the aid of a ball burnisher in surgically removed molars. All teeth were thermocycled for 500 cycles in water between 6 and 55 degrees C, then varnished until 1 mm from the sealant, submerged in 1% methylene blue for 4 hours, had roots dissected, crowns embedded in epoxy resin and sectioned before examination with a light reflection microscope.

Effects of glass ionomer sealants in newly erupted first molars after 5 years: a pilot study.

Objectives: The aim of the study was to investigate the caries-preventive effect of high-filled glass ionomer sealant in newly erupted first molars in a high-risk group. This investigation is part of a larger study amongst eight hundred and thirty-five 6-7-year-old Syrian children.

Methods: Children that had 1, 2 or 3 just erupted or erupting and at least one unerupted first molar (control) were enrolled in this pilot study.

Prevalence of caries and lesions treatable through the ART approach in high caries risk schoolchildren in Damascus, Syria.

Objective: To determine the prevalence of dentinal lesions treatable through the atraumatic restorative treatment (ART) approach for high caries risk schoolchildren.

Subjects And Methods: A convenience sample was taken of 1,542 grade 1 and 931 grade 2 children from 21 primary schools in a low socio-economic area in Damascus. Dentinal lesions in which the smallest excavator (diameter of 0.
