Dental injuries in inline skating – level of information and prevention

Abstract –  Inline skating belongs like ice hockey, rugby, and boxing to sporting activities with high-risk of suffering tooth accidents. Because of high velocity and loss of balance, especially on uneven ground, the injury potential in inline skating is higher. The objective of this work was to conduct a comparative study between Switzerland and Germany. The questions focussed on the frequency of tooth accidents, their prevention by mouthguard and the level of information about emergency measures after dental trauma and the resulting consequences for athletes. Using a standardized questionnaire totally 612 individuals, 324 men and 288 women, in two countries belonging to three different divisions (fun, fitness and speed) were surveyed. Fifty-six (9.2%) of these 612 interviewees have already experienced a tooth injury while inline skating. More than half of all interviewed players (68.3%) were aware of the possibility of replanting avulsed teeth. Only 32.4% were familiar with the tooth rescue kit. Just 65.4% knew mouthguard and only 1.9% of those athletes ( n  = 12) wore a mouthguard while inline skating. The results show that the area of inline skating requires more information about preventing dental trauma through sports associations and dentists.     

Orofacial/cerebral injuries and the use of mouthguards by professional athletes in Switzerland

Abstract –  The objective of the present study was to measure the occurrence of orofacial and cerebral injuries in different sports and to survey the awareness of athletes and officials concerning the use of mouthguards during sport activities. Two hundred and sixty-seven professional athletes and 63 officials participating in soccer, handball, basketball and ice hockey were interviewed. The frequency of orofacial and cerebral trauma during sport practice was recorded and the reason for using and not using mouthguards was assessed. A great difference in orofacial and cerebral injuries was found when comparing the different kinds of sports and comparing athletes with or without mouthguards. 45% of the players had suffered injuries when not wearing mouthguards. Most injuries were found in ice hockey, (59%), whereas only 24% of the soccer players suffered injuries when not wearing mouthguards. Sixty-eight percentage of the players wearing mouthguards had never suffered any orofacial and cerebral injuries. Two hundred and twenty-four athletes (84%) did not use a mouthguard despite general acceptance by 150 athletes (56%). Although the awareness of mouthguards among officials was very high (59%), only 25% of them would support the funding of mouthguards and 5% would enforce regulations. Athletes as well as coaches should be informed about the high risk of oral injuries when performing contact sports. Doctors and dentists need to recommend a more intensive education of students in sports medicine and sports dentistry, and to increase their willingness to become a team dentist.     

Possible disease transmission by contaminated mouthguards in two young football players

Previous studies have demonstrated that athletic mouthguards worn by ice hockey and football players harbor large numbers of bacteria, yeasts, and molds, some of which are either opportunistic or frank pathogens. This article details the clinical history of two junior high school football players. The first player had cellulitis of the leg after a non-break injury. The same unusual bacterium was isolated from both the athletic mouthguard and abscess cultures from the wound. The second patient suffered an attack of exercise-induced asthma so severe that his inhaler could not control the symptoms enough for him to resume play. This child's mouthguard was contaminated with five different species of mold. The clinical implications of mouthguard contamination, possible avenues of disease transmission, and recommendations for mouthguard care are discussed.     

The influence of impact object characteristics on impact force and force absorption by mouthguard material

Abstract –  Most impact force and impact energy absorption tests for mouthguards have used a steel ball in a drop-ball or the pendulum device. However, in reality most sports-related trauma is caused by objects other than the steel ball, e.g. various sized balls, hockey puck, or bat or stick. Also, the elasticity, the velocity and the mass of the object could change the degree and the extent of injuries. In this study, we attempted to measure the impact force from actual sports equipment in order to clarify the exact mechanism of dental-related sports injuries and the protective effects of mouthguards. The present study was conducted using the pendulum impact device and load cell. Impact objects were removable. Seven mobile impact objects were selected for testing: a steel ball, baseball, softball, field hockey ball, ice hockey puck, cricket ball, and wooden baseball bat. The mouthguard material used in this study was a 3-mm-thick Drufosoft (Dreve-Dentamid GmbH, Unna, Germany), and test samples were made of the one-layer type. The peak transmitted forces without mouthguard ranged from the smallest (ice hockey stick, 46.9 kgf) to the biggest (steel ball, 481.6 kgf). The peak transmitted forces were smaller when the mouthguard was attached than without it for all impact materials but the effect was significantly influenced by the object type. The steel ball showed the biggest (62.1%) absorption ability while the wooden bat showed the second biggest (38.3%). The other balls or the puck showed from 0.6 to 6.0% absorbency. These results show that it is important to test the effectiveness of mouthguards on specific types of sports equipment. In future, we may select different materials and mouthguard designs suitable for specific sports.     

Oro-facial injuries and mouthguard use in elite female field hockey players

Abstract –  The objectives of this study were to assess the prevalence of oro-facial injuries, frequency of mouthguard use and players' attitudes towards the use of mouthguards among elite English female field hockey players. All 140 players of the English Hockey Association female Premiere League were asked to complete a questionnaire. Main outcome measures were prevalence of oro-facial injuries, frequency of wearing of mouthguards and attitudes to mouthguard wearing. One hundred and ten completed questionnaires were returned (79% response rate). Facial injuries were common. Nineteen percent had sustained dental injury. Five percent of the respondents had at least one tooth avulsed. Eighty-eight percent of the players said that they owned a mouthguard. Mouthguards were worn regularly during matches by 69% but were used less frequently during training. Six percent thought that mouthguards were ineffective. Eighteen percent of the subjects refused to play if they did not have their mouthguard. Sixty-nine percent of the subjects felt that the mouthguards should be worn compulsorily at all times during the game. The following were finally concluded from the study: oro-facial injuries were commonly reported; 88% of the players possessed a mouthguard; and mouthguards were worn regularly during matches by 69% but were used less frequently during training.     

Dental trauma in contact team sports

Abstract Dental injuries occurring from 1979–1985 in Finland in 6 contact team sports (American football, bandy, basketball, team handball, ice hockey and soccer) were studied. A total of 23,395 accidents occurred among registered players; 1526 (6.5%) of these accidents affected the dental structures. Contact between players caused over half of the accidents and a blow from a stick every third accident. Crown fractures were the most common type of dental injury, occurring most often to the maxillary central incisors. In most accidents (58.6%) only one tooth was affected. The highest rate of incidence was found in ice hockey (8.9%) and the lowest in American football (1.4%). The low incidence in American football was due to adequate facial and dental protection that is mandatory in this sport.     

Mouthguard utilization rates during sport activities in Ankara, Turkey

Abstract –  The objective of this study was to determine the attitudes towards mouthguard use in Ankara, Turkey. In the first part of this study, an eight-item questionnaire was distributed to 22 coaches from 15 secondary schools randomly selected from five municipalities of Ankara, Turkey. The questionnaire sought information on how much coaches know regarding mouthguards and how often children and adolescents of the ages 11–18 use mouthguards. The second part of the study was based on the data obtained from direct interviews answered by 121 university athletes of three different sport modalities (football, ice hockey and martial arts). The purpose of this part of the study was to determine the rate of mouthguard use and the frequency and type of oral trauma in these athletes. The result of the coaches' questionnaires revealed that; none of the 11–18 years old children and adolescents used mouthguards while participating in sports. Of the coaches, 77.2% had seen orofacial trauma in this age group during sport activities and 95.5% of the coaches believed that mouthguards prevented oral injuries. Of the coaches, 72.7% reported that children and adolescents should use mouthguards in sport activities. The second part of the study showed that although all of the athletes owned mouth-formed type of mouthguards, the utilization rate was 74.4%. Of all players, 13.2% had suffered from one or more form of oral injury while not wearing mouthguards. The results show that in Turkey, the use of mouthguards has not become widespread in sports. It can be concluded that regular mouthguard use in sports should be encouraged in Turkey.     

Dental injuries in water polo, a survey of players in Switzerland

Water polo is a sporting activity which has a medium risk of causing dental trauma. Owing to the high speed, close body contact, and the combination of throwing and swimming that is inherent to the sport, the general injury potential is high. Using a standardized questionnaire for a total of 415 water polo players from Switzerland, this study examines the frequency of dental and facial injuries in water polo, athletes' habits regarding the wearing of mouthguards, and the general level of knowledge about emergency procedures following dental trauma. The participating players came from 6 divisions: Swiss national leagues A and B, first and second leagues, as well as the women's, and junior's league. The data were evaluated according to division and gender. Of the 415 interviewees, 185 (44.6%) had witnessed a dental injury in water polo. Eighty-seven (21.0%) players reported having suffered a tooth injury when playing water polo. Tooth fracture was the most stated dental injury [86 (16.4%)]. A similar number of tooth injuries were experienced by both male [355 (21.1%)] and female [60 (20.0%)] players. The interviewees over the age of 50 showed a higher incidence of tooth injuries than younger players (>50 years = 41.7%). Slightly more than half of the interviewed players [228 (54.9%)] were aware of the possibility of replanting avulsed teeth. As few as 43 (10.4%) players were familiar with tooth rescue boxes. Only 32 (7.7%) water polo players wore a mouthguard; the most common reason for not wearing a mouthguard was that it was seen to be unnecessary [169 (40.7%)]. This survey highlights the potential for improvement in the level of knowledge about dental injury prevention in water polo. In addition to information and guidelines from the relevant sports' associations, and coaches, dentists could also play a role in the provision of this education.     

Attitudes of Central Collegiate Hockey Association ice hockey players toward athletic mouthguard usage

OBJECTIVE: The purpose of this study was to examine Central Collegiate Hockey Association ice hockey players' attitudes regarding the use of athletic mouthguards and to determine the effects of mouthguard type, player position, education, and usage time with respect to attitudes. METHODS: A questionnaire measuring players' attitudes toward mouthguards was sent to certified athletic trainers (ATC) responsible for providing healthcare coverage at 10 institutions of the Central Collegiate Hockey Association (CCHA). The ATC's distributed the surveys to all the players on their respective collegiate teams. Out of a total of 265 players listed on the roosters of the CCHA, one hundred and sixty five (62%) players returned the surveys, with 158 surveys used in the analyses (60%). RESULTS: Approximately 13.3% of players (n=21) reported wearing mouthguards 50% of the time or greater during games and 3.8% (n=6) reported wearing mouthguards 50% of the time or greater during practices. Twenty-six percent (n=41) of the players never received educational information regarding using mouthguards. Thirty-nine percent (n=59) of the players reported altering mouthguards to obtain a better fit while 91% of the players were not influenced by the cost of the mouthguard. A 2 x 2 x 2 ANOVA revealed a significant interaction among player position and mouthguard type with respect to player attitudes (F(1,131) = 4.96, P < 0.05), with defensive players having more negative attitudes toward mouthguard usage compared to offensive players. CONCLUSION: No one specific factor affecting attitudes was identified, however, players reported limited educational opportunities to learn about the effectiveness of mouthguards. Therefore, coaches, dentists, and healthcare providers should engage in more preventive educational programs to increase player attitudes and compliance.     

The incidence and severity of dental trauma in intercollegiate athletes

BACKGROUND: The use of protective devices such as mouthguards during participation in contact sports may be effective in reducing the incidence or severity of dental injuries. METHODS: Dental injuries reported to the athletic department at the University of Southern California, Los Angeles, were recorded from 1996 through 2005. The authors classified each injury and determined the severity of the injury. Severity was defined in relation to the treatment required and the prognosis of the teeth and supporting tissues involved. RESULTS: Fifty-one traumatic dental injuries were reported. Basketball was the sport with the highest injury rate; it had an incidence rate (IR) of 10.6 injuries per 100 athlete-seasons among men, and an IR of 5.0 injuries per 100 athlete-seasons among women. The IR for men's basketball players was five times higher than that for football players for whom mouthguard use is mandatory. CONCLUSIONS: Given the relatively high incidence of dental injury in basketball and the potential of mouthguard use to reduce the incidence and severity of the trauma, mandatory use of mouthguards among collegiate basketball players should be considered. CLINICAL IMPLICATIONS: Dental professionals have a responsibility to educate patients and the public about the importance of using mouth-guard protection in contact sports.     

Dental squash injuries – a survey among players and coaches in Switzerland, Germany and France

Abstract –  Squash belongs to sporting activities with medium risk of causing dental trauma. Because of high velocity, close body contact and the use of rackets the injury potential in squash has increased. The aim of this work was to conduct a comparative study between Switzerland, Germany and France on a number of issues: the frequency of dental and facial injuries in squash, athletes' habits of wearing mouthguards, as well as the general level of information about emergency measures after a dental trauma and the resulting consequences. Using a standardized questionnaire a total of 653 individuals, 600 squash players and their 53 coaches, were interviewed. In each of the three countries 200 players belonging to four different divisions (juniors, amateurs, semi-professionals and professionals) were surveyed. Of these 653 interviewees 133 (20.4%) have already observed a dental injury; 27 (4.5%) have experienced a dental trauma themselves. Less than half of all interviewed players and coaches (47.6%) were aware of the possibility of replanting avulsed teeth. Just 5.1% were familiar with the tooth rescue kit. Only one individual wore a mouthguard. The results show that the area of squash requires more information about prevention through sports associations, coaches and dentists.     

Dental injury and its prevention in Swiss rugby

Abstract – Objectives: Rugby players are at a high risk of sustaining dental injury because of the high number of tackles implicit to the game. This study aimed to determine the frequency of injuries sustained by players in the Swiss rugby league. Methods: During the 2010/11 season, 517 rugby players from 19 clubs were questioned about dental trauma as well as the use of mouthguards and other forms of body protection. The level of awareness about tooth avulsion and replantation was also assessed. Participants included athletes from four different leagues; National (155), Premier (122), Women’s (90) and Juniors (150). Results: Of the 517 players taking part in the survey, 54.4% had sustained at least one serious injury and 39.5% had sustained a facial injury. One hundred and thirty‐nine athletes (37.3%) had observed another player sustain a dental injury during a game, whilst 35 (6.8%) had personally sustained one or more dental injuries. Dental injury rate was considerably higher amongst forwards than backs. Four hundred and fifty‐six players (88.2%) wore a mouthguard of which three‐quarters were tailor‐made. Three hundred and thirteen players (60.5%) were aware that an avulsed tooth can be replanted; however, only 27 (5.2%) had heard of the tooth rescue boxes. These results demonstrate that, whilst general injuries occur with regularity in rugby, dental injuries are not amongst the most common forms. This is almost certainly attributable to the high level of mouthguard usage. Particularly for players in the junior league, in which the use of mouthguards was lowest, the risk of dental injury may be reduced by an increased level of education about tooth protection. Conclusions: To this end, an increased awareness about and usage of tooth rescue boxes would be desirable. It would seem sensible to make the wearing of mouthguards compulsory in contact sports such as rugby.     

Dental trauma and level of information: mouthguard use in different contact sports

Abstract  – The objective of the present work was to study the occurrence of dental trauma in different sports, as well as to check if athletes used mouthguard during sport activities, and knew the siginificance of its utilization. The professional and semi-professional athletes who practised contact sports were interviewed, and were analyzed to determine the occurrence of dental trauma during sport practice, as well as if the athletes used a mouthguard and knew its indication. Results showed a high rate of dental trauma in athletes compared to the general population. The majority of athletes also demonstrated little utilization of mouthguard, in spite of the information about usage during sports practices and a general knowledge of its uses.     

Basketball players' experience of dental injury and awareness about mouthguard in China

Abstract –  The objective of the present study was to describe the occurrence of orofacial, particularly dental injuries in basketball, and to survey the athletes' awareness concerning the use of mouthguards during basketball training and competition. A pilot questionnaire was designed and tested with basketball players. Two hundred and thirty-six male athletes were surveyed. Seventy-seven players were professional players. Exactly 80.6% professionals and 37.7% semi-professional athletes had an experience of oral soft tissue laceration and dental injuries in basketball practice. The difference between the two groups is significant. The incidence of dental and oral injuries was related to the length of training time. About 59% of the athletes ranked the risk of orofacial and dental injury in basketball as medium. Although the awareness of mouthguards among the basketball players was very high (80.1%), only one of them had used the custom-made mouthguard. Most of the athletes gained the knowledge about mouthguards from foreign players (33.5%), media (24.8%) and teammates/classmates (24.3%). The influence of dentists was very weak. Athletes should be informed about the high risk of oral injuries when participating in contact sports. Dentists should play a more significant role in the program of promoting mouthguard use to prevent the occurrence of oral injury in sport participation.     

Does a free‐of‐charge distribution of boil‐and‐bite mouthguards to young adult amateur sportsmen affect oral and facial trauma?

Abstract –  The purpose of this retrospective study was to evaluate the compliance effectiveness of free-of-charge distribution of boil-and-bite mouthguards to amateur sportsmen who exercise and play without a formal team, a coach, or regulations. Several infantry units in the Israel Defense Forces distributed maxillary boil-and-bite mouthguards to their recruits. Target companies from these battalions and from similar battalions (comparison group -mouthguards not supplied), were selected. Soldiers were interviewed using a structured questionnaire. Of the 630 male participants, 272 received a mouthguard and 358 served as the comparison group. No differences were found between groups regarding demographic parameters or overall trauma cases. When compliance to a free-of-charge distributed boil-and-bite mouthguard was assessed, 93 (34.2%) participants reported using the mouthguard during sport activities. Compliance was high for martial arts, but low for other sports. Although the number of self-reported sport-related oral/dental trauma cases was similar between mouthguard users and non-users, the users group showed less severe injuries. However, free distribution to young amateur sportsmen does not affect oral and dental trauma unless accompanied by education and motivation.     

Do American football players in Turkey protect themselves from dental or orofacial trauma?

Abstract – Background/Aims: Dental and orofacial trauma in contact sports differs from other sources, as it is possible to prevent it and reduce the dental and orofacial trauma by using protection devices. The aim of this study was to evaluate the occurrence of dental or orofacial trauma in American football players of Turkey National League as well as to investigate if the players were aware of mouthguards (MGs) and had used any. Material and methods: An epidemiological survey was carried out through interviews with 78 American football players in four clubs competing in Turkey National League. Thirteen players had already been affected by orofacial trauma. Results and Conclusions: Results revealed that 67 of 78 Turkish–American football players were aware of MG, while 46 of 78 players also demonstrated its use. It should be concluded that from the moment a youngster starts practising football, he should be encouraged to wear an MG to get used to the sensation and, would automatically consider it as a part of the game. A great responsibility lies on dentists, to inform their patients about the importance of wearing MG and the consequences, if it is not worn.     

Eye injuries and orofacial traumas in floorball – a survey in Switzerland and Sweden

Abstract – The objective of this study was to investigate the occurrence of eye injuries and orofacial traumas in floorball. In addition, the athletes’ habits of wearing protective goggles and mouthguards was surveyed, and an assessment was made of the general level of knowledge amongst athletes and coaches about preventive and first aid measures after a dental trauma and the resulting consequences. The study was conducted by the same interviewer in Switzerland and Sweden during the 2009/2010 season using a standardized questionnaire. A total of 608 individuals (565 athletes and 43 coaches) belonging to the amateur and semi‐professional leagues in the two countries were individually interviewed. Although 72.7% of all athletes had observed and 27.7% of field players had sustained an injury to the eye or its vicinity, only 25 athletes (4.9%) wore protective eyewear. Similarly, despite 31.7% of all players having observed a dental or jaw injury and 11.3% of interviewed field players having suffered one, only one athlete wore a mouthguard on a regular basis. Participants from Switzerland were significantly better informed than participants from Sweden with regard to first aid measures. The results of this study show that floorball has an equally high risk for dental trauma as handball. Further investigations of dental injuries in floorball would be valuable in order to provide players, coaches, parents and sporting federations with the necessary information to make decisions regarding the use of mouthguards. It is strongly recommended that protective eyewear should be made mandatory.     

Prevention of craniofacial injuries in ice hockey

Prior to 1975, craniofacial injuries were the most frequent of all ice hockey injuries. Through the cooperative efforts of hockey administrators, health professionals, sports standards organizations, and the introduction of mandatory protective equipment playing rules craniofacial injuries in youth, high school, and college hockey players in the United States have been almost eliminated. Blind eye injuries, once a major problem, no longer occur in players wearing certified full face protectors. The saving in health care costs for treating eye injuries alone is estimated to be upwards of $10 million annually. Despite the phenomenal success of amateur hockey organizations in eliminating most craniofacial injuries, such injuries continue to occur in recreational, "Old Timers," major junior, and professional hockey players because of failure to use the most effective types of protective equipment. The system established in the United States for preventing craniofacial injuries in the sports of ice hockey that involves youth, high school, and college hockey associations along with standards setting and certification procedures can serve as a model for all amateur sports throughout the world.     

Evaluating the knowledge of sports participants regarding dental emergency procedures

Abstract –  Dental trauma is a common consequence of sports practice to which emergency treatment is critical. The purpose of this study was to evaluate the knowledge of sports participants about dental trauma procedures, particularly tooth avulsion. A specific questionnaire concerning concepts, experiences and behaviors after dental trauma and the use of mouthguard was standardized and validated with 80 people. The validated questionnaire was then distributed to 310 sports participants. The results showed that 28.4% had experienced a kind of dental trauma; 42.6% would look for a dentist for treatment; 51.7% reimplanted or would reimplant the avulsed tooth; 6.5% would maintain the avulsed tooth in milk. Although 47.4% of the participants were aware of the possibility of accidents during sports practice, only 13.9% reported to use a mouthguard. This study showed an overall lack of knowledge of sportsmen and sportswomen with regards to tooth avulsion, thus reinforcing the need for educational campaigns to improve the immediate emergency treatment of tooth avulsion.
