| 内容記述 | Various types of protective equipment for sports have been developed, such as mouth-guards used in the maxillo-oral region. Mouthguards are considered to exhibit excellent maxillo-oral injury-preventive effects, and their use is recommended in many sporting fields, particularly in contact sports. However, in previous studies on the injury-preventive effects of mouthguards, their impact absorbability was evaluated only by applying impact to mouthguard materials, and by inserting mouthguards into cranial bone models or extracted bovine teeth, without assuming actual impact to the body, or considering the presence of periodontal tissue consisting of the periodontal membrane, alveolar bone, and gingiva. Therefore, the effects of mouthguards on periodontal tissue have not been clarified. In this study, using a pendulum-type impact test machine, impact was applied to bovine mandibular bone bodies whose periodontal tissue had been preserved under conditions highly similar to physiological condition the actual effects of mouthguards, and influence of differences in the thickness and composition of mouthguard materials on the teeth and periodontal tissue were evaluated. The following results were obtained: 1. Impact force applied to the teeth and values for strain occurring in the teeth were significantly lower in the presence than in the absence of a mouthguard. 2. Similarly, the values for strain occurring in alveolar bone periodontal tissue area significantly decreased after wearing mouthguards, in contrast to the absence of mouthguards. 3. Impact force applied to the teeth and values for strain occurring in the teeth were significantly lower with a 4-mm-thick mouthguard than with a 1-mm-thick mouthguard. 4. Similarly, values for strain occurring in the alveolar bone periodontal tissue area (lingual side) were significantly lower with a 4-mm-thick mouthguard than with a 1-mm-thick mouthguard. 5. Differences in mouthguard materials did not cause any significant difference in the impact force applied to the teeth or the strain occurring in the teeth. 6. Differences in mouthguard materials did not cause any significant differences in strain occurring in the alveolar bone periodontal tissue area. These findings suggest that mouthguards decreased the values for strain and degrees of impact acceleration caused by impact force applied to the teeth and alveolar bone area, protecting the teeth and periodontal tissue. Furthermore, our study confirmed that the impact absorption effects of mouthguards on the teeth and periodontal tissue increased with increases in their thickness. It was also suggested that differences in mouthguard materials employed in this study did not show any significant difference in the impact absorption effects on the teeth and periodontal tissue. | |||||||
