Evaluation of the relationship between dental anxiety and oral health status of mothers and their children.

BACKGROUND: Mothers usually have the primary role in raising children and developing health-related behaviors. This study aims to evaluate the relationship between dental anxiety and oral hygiene status of mothers and children's dental anxiety and gingival health. METHODS: The study included 305 children, aged 4-12 years, who came to the dentist for the first time and their mothers. All the demographic and oral hygiene information were collected through a questionnaire. The dental anxiety of the mothers and children was assessed using the Modified Dental Anxiety Scale (MDAS) and Venham Picture Test (VPT), respectively. The oral examination of the mother and children was performed, and their PI, GI, and DMFT scores were recorded. RESULTS: While the correlation between MDAS and VPT was positive and strong in children aged 8-12, it was positive but weak in the 4-7 age group. A significant relationship was detected between the mother's PI, GI, DMFT, and the child's VPT score. According to the mothers' dental anxiety, there were no statistically significant differences in PI, GI, and dmft values in children aged between 4 to 7. A moderately positive and statistically significant relationship between maternal dental anxiety and children's DMFT was identified in children aged 8-12. CONCLUSIONS: Children's dental anxiety was significantly influenced by maternal dental anxiety, post-treatment complications experienced by the mother, and the oral health status of the mother.

Comparative analysis of shear bond strength of MTA and Theracal PT with different restorative materials.

BACKGROUND: This study aimed to compare the in vitro shear bond strength (SBS) of mineral trioxide aggregate (MTA) and dual-cured, resin-modified calcium silicate material (Theracal PT) to composite resin, compomer, and bulk-fill composite, and to evaluate the bond failure mode under a stereomicroscope. METHODS: Ninety acrylic specimens, each with a 4 mm diameter and 2 mm height central hole, were prepared. These specimens were randomly divided into two groups based on the capping materials: MTA and Theracal PT. Each group was further subdivided into three subgroups (n = 15) according to the restorative materials: composite resin, compomer, and bulk-fill composite. The specimens were then subjected to shear testing using a universal testing machine at a crosshead speed of 1 mm/min. Post-test, the fracture locations were examined using a stereomicroscope. Data were analyzed using a two-way analysis of variance (ANOVA) and the Tukey test. RESULTS: The SBS values for the Theracal PT group were significantly higher than those for the MTA group (p < 0.001). Within the MTA groups, no significant differences were observed in SBS values across the different restorative materials. However, a significant difference was found between the mean SBS values of the Theracal PT + composite resin group and the Theracal PT + compomer group (p < 0.001). CONCLUSIONS: Theracal PT shows promise in dentistry due to its superior bond strength. Given its bond values, Theracal PT appears capable of forming durable and long-lasting restorations by establishing reliable bonds with various restorative materials commonly used in dentistry.
