Filter by: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.
The aim of this study is to evaluate the efficacy of oral hygiene orientation singly, compared to resin-based sealants in controlling occlusal cavitated enamel lesions on primary and permanent molars. For this, 273 occlusal surfaces of primary molars and 273 occlusal surfaces of first permanent molars on 4-9 years-old children with an enamel cavitated lesion will be selected in 9 cities of Brazil. The surfaces will be randomly divides into 2 groups: oral hygiene orientation and resin-based sealant. The surfaces will be evaluated after 6 and 12 months regarding clinical and radiographic lesions progression. The costs and cost-efficacy of these treatments, children's discomfort, parents'/guardians' satisfaction and impact on quality of life will also be investigated. Poisson regression analysis will be performed in order to compare the groups, through clinical and radiographic criteria. This test will also be used to assess the association between the group and patient discomfort and parents' satisfaction. Time, costs and impact on quality of life of the treatments will be compared by Student's t test. For all analyses, the significance level will be set at 5%.
