This study evaluated the association of level of anxiety in children with and without sleep bruxism (SB). The study was performed with 84 six-to eigth-years-old children, divided into two groups: with bruxism (BG) and without bruxism (CG). Following the criteria purposed by American Academy of Sleep Medicine (AASM) to determine SB, the presence of tooth wear has been verified through clinical examinations, and the parents have answered a questionnaire about their children's behavior and habits. Additionally, the State-Trait Anxiety Inventory for Children (STAIC) was applied to parents of the selected patients. Data analysis revealed a statistical significant difference between the groups (Student's t-test, p = 0.0136). Based on the results, anxiety assessment revealed that children with bruxism have reached higher levels in the STAIC scale than the non-bruxism group. Therefore, it indicates a direct relationship between the presence of anxiety disorder and the onset of bruxism in children.

Gingival conditioning techniques in prosthodontics aim to overcome bone and soft-tissue defects that often compromise the outcome of restorations in terms of esthetics, function, and biocompatibility. Whatever the technique used, it is essential to reproduce a regular concave gingival outline in order to recreate the natural aspect of the relationship between teeth and gingiva, eliminating black triangles. Transferring the details of the conditioned soft tissue to the laboratory technician with precision may be challenging. The authors hereby propose a novel technique to transfer the clinical aspect of the conditioned soft tissue to the master cast, using a customized metal framework to help ensure accuracy.

Occupational exposure to dental amalgam poses a potential risk of increasing systemic mercury levels, although urine mercury levels in all the sample participants were below the limits of biologic tolerance.
