Abstract: The aim of this study was to investigate plaque retention and the condition of the gingiva adjacent to class V cavities restored with glass ionomer versus composite restoration and to compare the initiation of gingivitis around these restorations with that around enamel within nine month intervals.
Subjects and Methods: This study was conducted on thirty children (16 girls and 14 boys) aged (5-7) years; they were selected from the outpatient clinic of the Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Ain –Shams University.
The purpose of the study was clearly explained to the patients and they agreed by signing an “Informed Consent". The children were randomly assigned to either the Fuji IX or to resin composite 3M™ ESPE™ Filtek™ Bulk Fill Flowable.
Results: No statistically significant difference were seen in plaque and gingival index scores between the materials at the first three months but there was statistically significant increase in plaque and gingival index scores in Fuji IX group after three months till nine months intervals. At the enamel surface, as well as at Fuji IX and resin composite sampling sites; there was no statistically significant change in mean Log10 CFU of Streptococci counts and Actinomyces spp. counts.
