    Background: Dental anxiety is one of the prime reasons for discouraging children to receive dental treatment. Measurement of the dental anxiety is very useful to know the prevalence level among 6- to 12-year-old children. Thus, the aim of the study was to determine the dental anxiety among 6- to 12-year-old children using Modified Dental Anxiety Scale (MDAS) score.

    Materials and Methods: A total of 400 south Indian children in the age group of 6-12 years who had visited Dental College and Hospital were recruited in the study. Dental anxiety was measured before dental treatment using MDAS. Statistical analysis was performed using Wilcoxon signed rank test.

    Results: Of the 400 children, 240 (61.5%) had severe dental anxiety, 92 (23%) had mild anxiety, and 78 (17%) had no anxiety. Females had higher anxiety level compared to males. Many study subjects answered that local anesthesia (LA) injection was considered most fearful. Dental anxiety was highest in smaller age groups.

    Conclusion: In our research, high percentage of children had dental anxiety, so counseling before dental visits is very important to reduce the dental anxiety among these 6- to 12-year-old children.

    AIM: To determine the effectiveness of two different endodontic retreatment systems for the removal of laterally compacted gutta-percha (GP).

    MATERIALS AND METHODS: Sixty-three freshly extracted human maxillary central incisors were used for the study. The teeth were instrumented with K-flex files and obturated using lateral condensation technique with GP and AH Plus sealer. The teeth were divided into three retreatment groups, each group consisting of 21 teeth. Group I: D-RaCe desobturation files (D-RaCe); group II: ProTaper Universal retreatment files (PTUR); group III: Hedstrom files (H-file). After removal of GP, the teeth were split longitudinally and divided into three equal parts: Cervical, middle, and apical third. The middle and apical thirds of all root halves were examined using scanning electron microscope (SEM). The total surface area covered by the residual debris was evaluated using Motic Image plus 2.0 software. Statistical analysis was done by one-way analysis of variance (ANOVA) test with a p-value <0.05 used to determine significance and Tukey's multiple post hoc tests used for comparison between the groups, and 't' test was done for comparison between the thirds within the same group.

    RESULTS: The PTUR retreatment files showed overall better performance compared with D-RaCe files and H-files. The PTUR files performed better at middle third compared with others. The PTUR files and D-RaCe files performed equally at apical third better than H-files.

    CONCLUSION: ProTaper retreatment files are better compared with D-RaCe files and H-files for the retreatment of the previously endodontically treated teeth.

    CLINICAL SIGNIFICANCE: Highest efficacy for the removal of GP was shown by ProTaper Universal System followed by D-RaCe and H-file.

    AIM: This study aimed to assess the level of knowledge and attitudes for pit and fissure sealants among undergraduate Indian dental students.

    MATERIALS AND METHODS: A modified questionnaire consisting of 24 items was distributed to 280 undergraduate dental students comprising males and females of different years at MNR Dental College, Sangareddy, India. Descriptive statistics and Chi-square/Fisher's exact tests were used for statistical analysis. The data were computationally tested using Statistical Package for the Social Sciences (SPSS) Version 20, IBM SPSS Statistics software for Windows, Armonk, NY, USA.

    RESULTS: With the response rate at 100%, most of the respondents, i.e., 70.4%, were females and the remaining 29.6% were male. Regarding the level of study, 20.8% were in 3rd year, 43.8% in the 4th year, and 16.8% were in 5th year (internship). The respondents showed a reasonable level of knowledge about sealants, mostly being good with the theoretical concepts of the sealants. On the other hand, respondents showed insufficient knowledge about sealants in the clinical practice.

    CONCLUSION: Although a high proportion of undergraduate dental students showed adequate knowledge about dental sealants, there is a lag in putting that knowledge into work during the clinical practice. These findings suggest an urgent need of dental schools to include and/or update their curriculum regarding fissure sealants to reflect modern dental education that concentrates on evidence-based practice in pediatric dentistry and improve the dental health among the future generations by reducing the incidence of caries.
