    ABSTRACT: The purpose of this study was to evaluate and compare the tensile bond strength and microleakage of Fuji IX GP, Fuji II LC, and compoglass and to compare bond strength with degree of microleakage exhibited by the same materials. Occlusal surfaces of 96 noncarious primary teeth were ground perpendicular to long axis of the tooth. Preparations were distributed into three groups consisting of Fuji IX GP, Fuji II LC and Compoglass. Specimens were tested for tensile bond strength by mounting them on Instron Universal Testing Machine. Ninety-six primary molars were treated with Fuji IX GP, Fuji II LC, and compoglass on box-only prepared proximal surface. Samples were thermocycled, stained with dye, sectioned, and scored for microleakage under stereomicroscope. ANOVA and Bonferrani correction test were done for comparisons. Pearson Chi-square test and regression analysis were done to assess the association between the parameters. Compoglass showed highest tensile strength and Fuji II LC showed least microleakage. There was a significant difference between the three groups in tensile strength and microleakage levels. The correlation between tensile strength and microleakage level in each group showed that there was a significant negative correlation only in Group 3. Fuji II LC and compoglass can be advocated in primary teeth because of their superior physical properties when compared with Fuji IX GP.

    ABSTRACT: To assess the oral health status of autistic children in Chennai. DESIGN and Oral health status was assessed for 483 children with autism, solicited from special education schools, autistic child centres and therapy centres. Conditions assessed were plaque accumulation, gingival health, dental caries, malocclusion, developmental anomalies, oral injuries and restorations. Chi-square and Fisher's exact tests of significance were used to compare groups. Proportions test was used to compare the significance of the parameters between boys and girls. Autistic children with primary dentition showed significantly higher incidence of dental caries (24%), when compared to other oral conditions. Children with mixed dentition had more gingivitis (50%) and children with permanent dentition had more gingivitis (48.96%) and malocclusion (71.15%). All the oral conditions were seen more in boys than girls. Autistic children have significantly poor oral hygiene and higher incidence of malocclusion and dental caries when compared to other oral conditions.
