Description
Summary:Background/Aim The effectiveness of mouthguards used in field hockey is unknown. The aim of this study was to compare the maximum impact heights between currently used mouthguards in field hockey to prevent dental injury. Methods Four boil‐and‐bite mouthguards (Dita, Shock Doctor, SISU, and Stag) and one custom‐made mouthguard (Elysee) were tested for maximum impact height. A hockey ball was released in a tube from increasing heights onto plaster and polymethylmethacrylate (PMMA) dental models. Models were tested without mouthguard as a control. The experiment was repeated 10 times per mouthguard and for the control on each dental model. The maximum impact height for when the dental model broke was used to calculate the speed. The mouthguards and controls were compared. Results The maximum impact heights (median [25%‐75%] in meters) onto plaster dental models were as follows: control 0.23 (0.15‐0.25), Dita 0.35 (0.30‐0.35), Elysee 0.45 (0.34‐0.50), Shock Doctor 0.68 (0.60‐0.74), SISU 0.23 (0.20‐0.26), and Stag 0.35 (0.35‐0.46). The maximum impact height for Shock Doctor was significantly higher than all other mouthguards and the control (all P
