Background Previous studies have shown that it is necessary to evaluate adherence during the treatment process, using educational intervention methods which have been shown to improve adherence with patching treatment. A previous study reported that an educational cartoon had significantly improved adherence with patching. However, this black-white cartoon is not commercially available. Objective This study investigates the feasibility of a 4-minute educational cartoon video in improving adherence with patching therapy for amblyopic children. Methods Children (3 to 10 years old) with unilateral amblyopia who were prescribed 2 hours or 6 hours of patching per day were enrolled. Objective adherence to the treatment was tracked using a microsensor. Children returned after 4 weeks ± 2 days to measure adherence. Participants with adherence ≤50% were eligible to watch the educational cartoon video. They continued with the previously prescribed treatment (2 hours or 6 hours patching) for an additional week to evaluate the follow-up adherence. Results A total of 27 participants were enrolled. The mean age (SD) was 6.6 (1.5) years. Twenty-two participants (12 in the 2 hours patching group and 10 in the 6 hours patching group) had adherence ≤50% and watched our cartoon video. The cartoon video improved mean adherence (SD) from 29.6% (11.9%) to 56.8% (12.1%) in all 22 participants from both regimens (paired 2-tailed t -test, t = −11, P < 0.000). Conclusion The Educational cartoon video is feasible for use in a clinical setting. These data showed a trend of improvement in adherence with both patching regimens in children after watching the educational cartoon video.
Push-out bond strength (POBS) and failure analysis of gutta-percha and Martens hardness (MH) of canal dentin sealed with Bio-ceramic sealer (BCS). Specimens underwent endodontic treatment. Based on the method of disinfectants, specimens were classified into 4 groups. Group 1:5.25% NaOCl+Q-mix, group 2:ECYL+Q-mix, group 3:LGE+Q-mix, and group 4:RBP+Q-mix. Before obturation MH was assessed using a microhardness tester. Canals were obturated, and sealed with Bio-Root RCS. Each root was cut horizontally in 2 mm thickness and placed under the indenter of the universal testing machine. One-way analysis of variance and the Post Hoc Tukey test for group comparisons as statistical analysis. Samples with (5.25% NaOCl+Q-mix) displayed the highest bond integrity of BCS (8.00±0.24 MPa). The lowest POBS was demonstrated by the apical section of group 4 (RBP+Q-mix 2 in 1) (4.10±0.94 MPa) specimens. Group 2 (ECYL+Q-mix) and group 3 (LGE+Q-mix) exhibited comparable outcomes of bond scores to group 1 specimens (p > 0.05). MH was significantly lower in group 4 compared to group 1, group 2, and group 3 (p <0.05). The bond strength of BCS and MH of canal dentin is influenced by the type of irrigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
