Performance of Glass-ionomer Cements: 2-year Follow-up

Performance of Glass-ionomer Cements in the Pit and Fissure Sealing and Atraumatic Restorative Treatment: a Randomized 2-year Clinical Trial

The purpose of this randomized clinical trial was evaluate the performance of two conventional glass-ionomer cements in the pit and fissure sealing and atraumatic restorative treatment in high caries risk children.

Sealants were applied on sound permanent first molars by "press finger technique" and carious deciduous molars that required either class I or class II restorations were restored according to manufacturers' recommendations in order to caries prevention and control.

Inclusion Criteria:

• Volunteers that having at least two permanent first molars of opposite sides of the mouth, erupted in the oral cavity, caries-free and high-risk disease (presence of white spots, history of caries, plaque in smooth surfaces and gingivitis);
• Children who had one or two bilateral matched pairs of carious deciduous molars that required either class I or class II restorations.

Exclusion Criteria:

• Children who did not meet the minimum requirements for the achievement of sealants or parents / guardians did not agree to participate;
• No history of spontaneous pulpal pain.
