sealing of occlusal dentin caries in primary molars.

Conditions: Caries; Dentin; Fissure, Dental; Dental Caries in Children; Glass Ionomer Cement; Fissure Sealants

Summary: background a simple method for arresting dentin caries with a tight seal of the cavity would exclude the need for injection and excavation, reduce the risk for dental fear and possibly postpone or eliminate the need for further treatment. aim the aim is to evaluate success-rate and children's subjective experience of resin-based sealing (rbs) and resin-modified glass ionomer cement (gic) for treatment of occlusal dentin caries in primary molars. design children aged 2-9 years will be recruited to undergo rbs- or gic-treatment treatment for occlusal dentin caries in primary molars. a parent will answer the short form of children's fear survey (cfss-ds; parental version). no excavation but etching with 38% phosphoric acid will precede rbs. topical and local anaesthesia and excavation with high speed bur will precede gic. time for treatment will be estimated. the children will rank their experience of each treatment on a 7-grade face scale. the dentist will evaluate the child's experience, cooperation and the overall experience of the treatment on a four-grade scale. the treatment will be evaluated as "without remark" or "defective" after 3, 6, 12, 24 and 36 months. for statistical analysis the chi-2-test, wilcoxon-signed-rank-test and paired t-test will be used.
