Comparison of retention rates of fissure sealants using two flowable restorative materials and a conventional resin sealant: two-year follow-up

The purpose of this clinical study was to compare the retention rates of two flowable restorative systems [Admira Flow and Grandio Flow] with that of a conventional resin-based sealant [Fissurit F]. The study was planned as a clinical trial with a split-mouth design. A total of 122 sealants [38 Admira Flow, 41 Grandio Flow, 43 Fissurit F] were randomly applied to completely erupted permanent molars in 35 patients aged 9-20 years and followed up for 24 months. Data were analyzed using Pearson's X[2] and multiple comparison tests. At the end of the follow-up period, Fissurit F had higher retention rates [81.0%] than both Admira Flow [60.5%] and Grandio Flow [57.1%], with p < 0.05. However, there was no significant difference in caries development among groups [p > 0.05]. The two flowable composite resin materials used as fissure sealant were less retentive than the conventional resin sealant

Prevalence of dental anxiety in 7- to 11-year-old children and its relationship to dental caries

The aims of this cross-sectional study were to evaluate the level of fear of dental procedures among schoolchildren and assess the relationship between caries experience and fear of dental procedures. 275 children aged 7-11 years were recruited for the study. Before conducting a dental examination, each subject was asked to independently complete a Children's Fear Survey Schedule - Dental Subscale [CFSS-DS] questionnaire. Children having a score of >38 were included in the group 'with dental fear while those scoring <38 were placed in the 'without dental fear' group. All dental examinations were performed on the school premises according to WHO criteria. Mean CFSS-DS value was 28.1, and the number of children who experienced dental fear was 40 [14.5%]. It was found that Decayed, Missing and Filled Surface Index [DMFS-dfs] increased significantly with increasing CFSS-DS values. Fear scores were highest for 'Choking' [3.3], Injections' [2.6] and Having somebody put instruments in their mouth [2.6]. No significant differences in fear scores between boys and girls were found in this study. The data showed prevalence of dental fear in the 7-11-year-old children of this study. Dental fear scores decreased with increasing age
