    Notes: Abstract— The use of mouthguards in contact sports effectively prevents oral injury and preserves oral structures. We investigated oral injuries and awareness concerning mouthguards ainong Japanese high school soccer and rugby players. Athletes were asked a series of questions concerning their history of oral injury while participating in sports, and their pattern of mouthguard use was determined. The data were evaluated statistically using chi-square analysis. The incidence of oral injuries was 32.3% for soccer athletes and 56.5% for rugby athletes, with 0.8% and 24.1% of the respective groups having mouthguards. There were sigmficant differences between the soccer and rugby groups (p〈0.001). Although 81.8% of soccer athletes thought mouthguards were unnecessary, only 26.2% of rugby athletes shared this opinion and there was a sigmficant difference between the soccer and rugby groups. Many soccer ath-letes had insufficient knowledge about mouthguards and were not concerned about preventing oral injury, although it was in fact a common problem in their sport. Athletes as well as coaches must be made aware of the high risk of oral injury when playing soccer, rugby, and other contact sports.

    Notes: Mandibular angle fractures have been considered attributable to the presence of unerupted third molars. We examined the relationship between the incidence of sports-related mandibular angle fractures and the presence of a mandibular third molar with emphasis on the position of the third molar. The incidence of angle fracture was significantly higher in the sports-related injury group than in the group with fracture due to other causes (P〈0.05). The incidence of angle fracture in the athletes with higher impaction scores was significantly higher than that in the subjects with higher scores who did not have sports-related fractures (P〈0.05). The percentage of rugby athletes with third molars was significantly higher than that of those without third molars (P〈0.001), and a high proportion of young athletes (89.5%) was considered to belong to a potential high-risk group for angle fractures. Our findings suggest that mandibular angle fractures are influenced by the presence and characteristics of the third molar in sports-related injuries.

    Immunohistochemical analysis of cells in mucosal lesions of oral lichen planus (1988)

    Notes: We immunohistochemically analyzed the immunological background of the pathogenesis of oral lichen planus (OLP). Abundant lymphocytes infiltrated OLP mucosal lesions, particularly in satellite cell necrosis (SCN) regions, and cytotoxic/suppressor T lymphocytes were predominant in seven of 10 OLP cases. Some carried IL-2 receptors, particularly in SCN. Keratinocytes of the mucosal lesions expressed both HLA-ABC and HLA-DR antigens. This suggests that activated cytotoxic/suppressor T lymphocytes may play a major role in cytotoxity to keratinocytes as effector cells in OLP. OKM1-, OKM5+, HLA-DR+ and IL-1+ cells, vascular endothelial cells and clusters of spindle-shaped or oval cells, which had the same surface characteristics as a monocyte macrophage subset, were abundant and, together with migrating lymphocytes, might play a role in the immune response in mucosal lesions of OLP.
