Evaluating the knowledge of sports participants regarding dental emergency procedures in National Sports University, Imphal

Irrigation is a key part of successful root canal treatment as it fulfils several important mechanical, chemical and (micro) biological functions including the healing of periapical tissues.


Introduction
Dental trauma during sports is the major associated factor which links dentistry and sports. This is one of the most recent and evolving dental sectors. Sports dentistry is the treatment of sporting oral / facial injuries and associated oral disorders and manifestations. It has two main components: First to treat orofacial injuries and second to avoid sport-related orofacial injuries [1].
Sports dentistry is the branch of dental sciences include prevention, protection and clinical management of oral and maxillofacial region of athletes and sports active members, it also deals with the safety precautions towards orofacial region and its disorders. Hence precaution, prevention and safety measures are the key factors in avoiding oral and maxillofacial injuries [2]. For all sports, particularly contact, it is normal for children to get injured, with face being the principal area of injury. As dentists, we have different types of dental and facial bone fractures to deal with [3].
The face is the body's most defenseless area, and is often the least protected area. About 11-40 per cent of all sport injuries involve the face. Such injuries most frequently occur by clashing with impacts from a ball or surface or from player to player. A blow to the face may not only infl ict damage to the tooth or soft tissue, but can also lead to fractures of the jaw or facial bones, or even head injury. The complex facial anatomy Citation: Gautam  Only the principal investigator had access to the data and no personal details (e-mail address, phone number, name, etc.) were required. Responses were sought from only those players who are involved contact sports like boxing, Tae kwon do and mixed martial arts (MMA) and a submission was considered only when the 'submit' button was clicked at the end of the questionnaire (inclusion criteria). Among total submissions, if a sportsperson failed to answer ≥1 question, it was excluded from the analysis.
The study duration was from 1 st August 2020 to 25 th august, 2020, and both convenience sampling (researchers themselves contacted players to participate in the study) and snowball sampling (the participating players were asked to forward the questionnaire to their colleagues) were used so that maximal participation could be ensured.

Results
Out of 90 participants 30 each were boxers, mixed martial arts, and taek-wondo players who fi lled the questionnaire.
Differences in their responses were noted among the three groups (Table 1).
In our study majority of players (86.7%-96.7%) encountered trauma while playing and 70%-93% of participants among them has previous experience in managing those trauma cases. Majority of participants reported that soft tissue injuries (70%-80%) are more common than hard tissue injuries (20%-30%) while playing. Only 13.3% -40% participants knew that tetanus toxoid injection is necessary in dental trauma cases while 33%-60% of participants has no idea about such measure. On knowledge regarding management of these soft tissue tears 10%-33.3% reported they wipe the area neatly and apply turmeric over it, 30%-33% participants apply an ointment /dettol /spirit and 33.3%-60% prefer to visit a dentist. Only 30%-33.3% participants of our study reported to seek professional help immediately if a permanent tooth has been knocked out, and 23-26.6% reported to seek help within 30 minutes. Majority (30%-66.7%) participants of our study do not knew the concept of replant ( put back) the tooth into the socket from which it came in case of trauma, and only 6% -16% of players were aware of this concept and rest participants has no idea. Only 13.3%-50.3% players reported that they will Scrub the tooth gently with a tooth brush to replant a tooth back it the socket if it has fallen into the ground and was covered in dirt, 6%-23.3% reported that they will prefer to rinse the tooth under the tap water and 80% of taekwondo players reported that they will put the tooth straight back into the socket without doing anything. poses a challenge for the physicians to diagnose and treat these injuries [4].
Contact sports are described as those sports in which players communicate physically with each other in an effort to prevent the opposing team or person from winning [5]. The

Injuries has identifi ed the most common form of dental / orofacial injuries suffered during sports participation, which include lacerations of the soft tissue, abrasions and contusions, intrusions of the dents or avulsions, fracturing of the crown or / and the root, loss of one or more teeth of maxillary incisors most often [6].
Andersson and Bodin [7] stated that the determining factors for a favorable prognosis of replantation of avulsed tooth are minimal time of the avulsed tooth outside the socket, the storage and transportation medium of the avulsed tooth, and also minimal handling of the root surface and the periodontal ligament. They also stated that prognosis of reimplanted tooth is largely determined in the fi rst 15 min after avulsion. This states that immediate reimplantation is a necessity to achieve a better prognosis on reimplanted tooth [7]. According to the study conducted by Andreasen and Hjorting-Hansen [8], teeth that were reimplanted within 30 min gave a success rate of 90%, while only 5% chances of retention to those that were reimplanted after 2h.
The less common trauma involves zygoma fractures, mandibular fractures, alveolar fractures and temporomandibular joint trauma. Temporomandibular sport injuries and disorders may be caused by direct blows to the temporomandibular region, and indirectly by blows to the chin or laterally to the lower jaw where the force is transferred to one or both jaws. At the same time, the surrounding muscles, articular and extraarticular ligaments, articular disks and capsules, teeth can dissipate and modify the pathogenic effect of force [6].
Orofacial injuries have common consequences and are troublesome. These injuries can affect aspects of life physically, mentally, socially, and economically. Physically, orofacial injuries can lead to abnormal primary teeth exfoliation, permanent teeth eruption failure, unfavorable color changes in the teeth, painful abscesses and dental loss resulting in the injured victim's mouth unesthetic gaps [9]. Protection from sport-related orofacial injuries currently comes in the form of three shielding equipments: mouth guards, facemasks, and helmets [10]. Therefore, this study was conducted to assess the knowledge regarding prevention of traumatic injuries among contact sports players of National Sports University.

Materials and methods
Our study population consisted of players of National Sports University. The players consent to participate in the study (inclusion criteria) was implied when they clicked on the 'next' button to answer the questionnaire, and they had complete freedom either to decline or answer the questionnaire.
Citation: Gautam  Through results we arrived at the conclusion that Tae kwon do players has more (facial) injuries as compared to MMA and boxing as the difference between taekwondo and MMA / boxing statistically signifi cant.

Discussion
Sports can be fun time or a moment of competition. But such fun or competitions can be marred by the unwanted injuries infl icted during sports activities [11].
In our study 96.7% of Tae kwon do and 86.7% of MMA and boxers encountered trauma whilst playing amongst which 93.3% of the taek-wondo players, 70% of MMA and boxers had previous experience in managing trauma cases. This is found in disparity to the study performed by Zazryn TR, McCrory PR, Cameron PA among Australian professional boxers was found to be 23.3% [12] and at the same time 23.6%. in study conducted by Ngai KM, Levy F, Hsu EB among American mixed martial arts competitors [13].
In present study the greatest numbers of participant with dental injuries (96.7%) are of Tae kwon do, which is in a contrast to a study conducted by conducted by Jehad Ajarmah et al (30%) [14].
In present study participants most often came across soft tissue injuries (lip, tongue, cheek etc) which was found similar to the results of the study by Chan, et al. [15] In this study, 36.7% boxers, 40% MMA athletes and 13.3% Tae kwon do players agreed that tetanus toxoid injection is necessary in cases of dental trauma. According to research conducted by Fujita Y, Shiono Y, Maki K thorough attempt must be made to determine whether a patient has completed primary immunization. Children with unknown or uncertain previous immunization histories should be considered to have no previous tetanus toxoid doses [16].  using antiseptics, spirit or ointment and it was surprising to know that urban participants preferred the traditional method of managing injuries like application of turmeric in spite of readily available modern medicaments [17].
In our study majority of players believed to take immediate action in case of avulsed tooth which was found similar to the study conducted by Andersson and Bodin who have further stated that the prognosis of reimplanted tooth is largely determined in the fi rst 15 min after avulsion. This states that immediate reimplantation is a necessity to achieve a better prognosis on reimplanted tooth. 7 According to the study conducted by Andreasen and Hjorting-Hansen [8], teeth that were reimplanted within 30 min gave a success rate of 90%, while only 5% chances of retention to those that were reimplanted after 2h [18]. were familiar with the tooth rescue kit while in our study 6.7% boxers, 16.7% MMA athletes and 16.7 % Tae kwon do athletes were aware of replanting avulsed or knocked out tooth which was comparatively low [20]. Different storage media can be used for an avulsed tooth: Milk, saliva, saline solution, and water (in order of preference). Although water is the most readily available, it should be the last option because it causes lysis of vital periodontal cells. 21 In present study 23.3% boxing and MMA players and 3.3% of the Tae kwon do athletes reported that they will carry avulsed tooth in water medium in case of avulsion.

Conclusion
While contact sports pose a relatively high risk for dental and orofacial trauma, proper treatment can improve outcomes. Prompt referral for complicated crown fractures and temporomandibular joint dislocations is paramount. A toothsaving kit is useful on the sideline. If not available, an avulsed tooth can be transported in milk or saliva. Mouth guards can reduce or eliminate dental injury in most cases.
