Background Providing restorations to anterior teeth in children is a challenging task due to the need for high esthetics, strength, and durability. This study was done to compare prefabricated primary zirconia with resin composite strip crowns on primary maxillary central and lateral incisors with regards to gingival health, plaque accumulation, recurrent caries, restoration failure, and opposing teeth wear over a period of 3, 6 and 12 months. Methods Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who needed restorations were screened for inclusion criteria. A total of 120 teeth were treated; 60 with zirconia and 60 with strip crowns. Randomization was done by simple random allocation using SPSS software version 20.0 (Armonk, NY; IBM Corp.). A simple descriptive statistic was used for analysis by Wilcoxon Signed-Rank test and Chi-square test. Level of significance was set at (α = 0.05) and level of confidence at (95%). The presented research was registered retrospectively at ClinicalTrials.gov in 6th of August 2017, under registration number NCT03184012. Results Zirconia crowns showed significantly less gingival bleeding at the 3- and 6-months follow up periods (p < 0.006, p < 0.001; respectively), less plaque accumulation at all follow up visits (p < 0.001), no restoration failure (p < 0.001), but more wear to opposing teeth (p < 0.02). No significant difference was found between the two crowns with regards to recurrent caries (p < 0.135). Conclusion Based on our data we conclude that overtime teeth covered with zirconia crowns show better gingival health and less bleeding, plaque accumulation as well as less loss of material. On the other hand, zirconia can cause more loss of opposing tooth structure.
Autism spectrum disorder (ASD) prevalence has escalated in the last few decades; it is common to have children with ASD seek dental treatment. Their unique behavior patterns prevent them from attending a regular dental setting and receiving proper oral hygiene instructions (OHI); therefore, culturally adapted dental visual aids are necessary to teach them proper OHI. The aim of this study was to assess the effectiveness of culturally adapted dental visual aids in improving oral hygiene (OH) status in children with ASD. A blinded, randomized, controlled clinical trial with sixty-four children with ASD were randomly divided into two groups according to the type of dental visual aids given to them. The experimental group received culturally adapted dental visual aids developed specifically for the study, and the control group received regular dental visual aids. OH status was assessed before and after using the dental visual aids, and data were processed using SPSS version 25.0. OH status improved significantly in both groups after using the dental visual aids (p < 0.001, p < 0.001), respectively. The experimental group showed significant improvement in comparison to the control group in OH status (p = 0.030). Both dental visual aids showed effectiveness in improving OH status in children with ASD.
Autism spectrum disorder (ASD) prevalence has risen dramatically in recent decades; it is now common for children with ASD to seek dental care. Because their distinct behavioral patterns prevent them from receiving dental care in a traditional dental clinic, structured dental visual aids are required to help prepare them for their dental appointment. This study aimed to test the effect of “culturally adapted dental visual aids” in decreasing anxiety levels during dental visits in children with autism spectrum disorder (ASD). A randomized, controlled, blinded clinical trial was performed. Sixty-four children with ASD ages 6–12 years were assigned randomly into test and control groups based on the type of dental visual aids they received. The test group received “culturally adapted dental visual aids” created especially for the study, and the control group received “regular dental visual aids”. Anxiety levels were assessed before and after using both dental visual aids. All data were processed using SPSS version 25.0. The test group had a significant decrease in anxiety levels compared to the control group (p < 0.001). The “culturally adapted dental visual aids” have effectively reduced anxiety levels in children with ASD during dental visits.
