Effect of Acid Etching and Er: YAG Laser Enamel Conditioning on the Microleakage of Glass Carbomer Fissure Sealants
(Univ indonesia, Fac dentistry, 2020) Ozveren, Neslihan; Uslu, Yesim Sesen; Donmez, Nazmiye
Objective: This study aimed to evaluate the effects of Er:YAG laser used alone or in combination with acid etching as surface conditioners on the microleakage of a glass carbomer fissure sealant for permanent molar teeth. Methods: Forty sound human permanent molar teeth were randomly divided into four experimental groups based on enamel etching methods: group I, no surface conditioning; group II, 37% phosphoric acid etching; group III, Er:YAG laser etching; and group IV, sequential laser etching and acid etching. After surface conditioning procedures were conducted, the teeth were sealed with a glass carbomer seal. The teeth were subjected to thermocycling with 2500 cycles at 5 +/- 2 degrees C to 55 +/- 2 degrees C for 24 h. Subsequent microleakage was assessed via dye penetration under a stereomicroscope. Results: Group II showed the lowest microleakage scores. Groups III and IV exhibited similar score distribution, which was lower than that of group I. Conclusions: Laser etching and acid etching decrease the microleakage probability of glass carbomer sealants, and acid etching alone provides a more suitable surface for these sealants. Sequential laser etching and acid etching have no additional benefit in comparison with acid etching alone and yield worse results than those of the other tested methods.

Effectiveness of an educational cartoon animation on the knowledge of children about traumatic dental injuries
(Wiley, 2022) Ozveren, Neslihan; Yildirim, Sinem
Background/Aim: Although children are frequently exposed to traumatic dental injuries (TDIs), their knowledge and attitude regarding the emergency management of TDIs are largely insufficient. The aim of this study was to determine the knowledge of children about TDIs utilizing a questionnaire before and after watching a custom animated instructional video. Material and Methods: The study was conducted with 332 children aged 8 to 13 years. The children were asked to complete a 3-part questionnaire that included socio-demographic data, past experiences related to TDIs, and knowledge of the emergency management of TDIs. An educational video containing evidence-based information about the management of TDIs was shown to the children. They then completed the questionnaire again immediately after viewing the video and 1 week later. The data were analyzed using Friedman's two-way ANOVA by ranks test, McNemar's test, and the Mann-Whitney U-test. Results: The children's scores increased significantly following the viewing of the video (p = .0001). Prior to watching the animation, children who had previously received dental trauma education had considerably higher scores than their peers (p = .004). The animation was considered to be beneficial by 96.7% of the children. Prior to watching the animation, 49.1% of the children believed they could help their friends in the event of dental trauma, and after viewing the animation, this rate increased to 86.4%, but decreased to 77.1% after 1 week (p < .001). Conclusions: After watching the video, the children's scores improved dramatically and their self-confidence in helping their friends in the event of dental trauma increased.
