Mouth guards protect against orofacial and dental injuries in sports. However, special fitted dental splints have been claimed to improve strength and speed and, therefore, to enhance athletic performance. Purpose: To test the effects of a neuromuscular fitted dental splint in comparison with a habitual verticalizing splint and a no-splint condition on cycling sprint performance in the Wingate Anaerobic Test (WAnT). Methods: Twenty-three men (26.0 ± 2.0 y, 1.82 ± 0.06 m, 79.4 ± 7.7 kg) performed 3 WAnTs, 1 with the neuromuscular fitted splint, 1 with a habitual verticalized dental splint of the same height and material, and 1 under control conditions without any mouth guard, in randomized order separated by 1 wk. Results: No differences between any splint conditions were found in any aspect of WAnT performance (time to peak power, peak power, minimum power, power drop, and average power). Moderate to nearly perfect correlations between all splint conditions in all WAnT outcomes with coefficients of variation between 1.3% and 6.6% were found. Conclusions: Irrespective of habitual verticalization or myocentric positioning, dental splints have no effects on any aspect of WAnT performance. Results are comparable to those of test--retest experiments. [ABSTRACT FROM AUTHOR]

Roberts, AH, Walden, AJ, Carter, KA, and Symons, TB. Effect of sport-specific constraints on aerobic capacity in high school field hockey players. J Strength Cond Res 36(2): 493–497, 2022—Many sports require the use of a mouth guard (MG) and carrying an object during play. Research has shown that individually these conditions can cause performance decrements; however, no research has been conducted into the effect of combining both mouth guard and stick with adolescent female field hockey players. This study aimed to determine the effects of MG and stick (STK) use on estimated aerobic capacity over the course of a season long training and competition period. Thirty-eight female high school field hockey players were separated into 2 groups: experimental (EXP—all training with MG-STK) or control (CTL—all training without MG-STK). Aerobic capacity was estimated using a multi-stage fitness test. Field hockey specific training prescribed by coaching staff was performed throughout the study, with testing at pre-, mid- and post-season. Subjects performed 2 sets of testing at each time point, first without MG-STK (WOMG-STK) and then with MG-STK. No main effect was observed in aerobic capacity estimations between groups; however, MG-STK testing reduced estimated aerobic capacity at each time point, regardless of the group (WOMG-STK: 37.4 ± 6. mL·kg−1·min−1 vs. MG-STK: 33.2 ± 4. mL·kg−1·min−1; p < 0.01). Chronic use of MG-STK does not seem to negatively impact estimates of aerobic capacity over the course of a season in high school field hockey players. Therefore, players should be encouraged to use MGs during all training sessions as it increases safety and familiarity with no decrement in long-term physiological performance. [ABSTRACT FROM AUTHOR]

Introduction: Despite increase in the knowledge about reduction of dental injuries after tonsillectomy, the incidence is still considerable to attract attention. Presently gauze pieces, rubber or soft plastic materials are used. Hence, it was attempted to use a soft elastomeric putty dental material for this purpose which moulds perfectly to the shape of the upper dentition when applied and also gives full coverage of teeth with no reduction of the space when mouth is opened for surgery. It also gives better protection to the upper dentition as the gag fits perfectly on to it when applied. This, unlike gauze piece threads does not get interwined between the gaps of malaligned, prominent or crooked teeth, thereby offering superior protection. Aim: To describe the feasibility of custom fabricated teeth guard for Boyle Davis mouth gag in oral and oropharyngeal surgeries. Materials and Methods: An cross-sectional study was conducted in the Department of Ear, Nose and Throat, Mahatma Gandhi Medical College, Puducherry, India, in association with Indira Gandhi Institute of Dental Sciences, kerala, India, from February to April 2019. The equipment was simple, comprising of a paste of elastomeric silicone putty which had a base and catalyst which was custom made for the patient, just minutes before application over the patient’s upper dentition and over which the Boyle Davis mouth gag was applied and then the mouth opened for surgery. Total 50 consecutive patients, in the age group of 6-18 posted for tonsillectomy, were inserted with the equipment before application of Boyle Davis (BD) gag. The ease of insertion with a score of 1-4 was recorded from the surgeon. Postoperatively, once the gag was removed along with the custom made putty, the patient’s upper dentition was examined to look for any dental injuries that might have occurred due to gag insertion. The comfort level was assessed by a targeted questionnaire over a scale of difficulty from 1-4, 1 being comfortable and 4 being difficult. Results: The mean age of the patients was 10.56 years with the mean weight of 38.55 kilograms. There were 27 males and 23 females. In all the patients, pre and perioperative period was uneventful. The ease of insertion score was 1 in all the 50 patients; there were no oral injuries and no residual side-effects due to the material used. The mean score for comfort level was 1.8. Conclusion: An indigenously made elastomeric teeth guard is extremely effective in preventing dental injuries after application of Boyle Davis mouth gags in cases of adenotonsillectomy under controlled general anaesthesia.

Sports dentistry is one of the most important and upcoming fields in dentistry. Sports dentistry includes the prevention and management of athletics-related orofacial injuries and associated oral cavity diseases. The most noteworthy angle in forestalling sports-related orofacial injuries is guarding up with defensive devices, for example, appropriately fitting helmets, face masks and additionally mouth guards. Athletes are not well versed of the health implications of a traumatic injury to the mouth or of the potential for incurring severe head and orofacial injuries while playing. The dentist can play an essential role in notifying athletes, coaches and patients about the importance of preventing orofacial injuries in sports. The present article aims to elevate professional awareness and interest towards sports dentistry and the injuries. [ABSTRACT FROM AUTHOR]

A loose tooth is a great concern for anaesthesiologists either as a potential foreign body or a bleeding source. A 48-year-old male patient scheduled to undergo a lumbar discectomy had a loose maxillary incisor; he got his tooth fixed by using a thermoplastic external nasal splint. Different approaches such as modification in laryngoscopy or removal of loose teeth have been proposed, but fixing and keeping it in place is not a usual practice which was successfully applied for our patient. Loose incisors could be fixed and protected by using a thermoplastic nasal splint as a mouth guard. [ABSTRACT FROM AUTHOR]

Introduction: Despite increase in the knowledge about reduction of dental injuries after tonsillectomy, the incidence is still considerable to attract attention. Presently gauze pieces, rubber or soft plastic materials are used. Hence, it was attempted to use a soft elastomeric putty dental material for this purpose which moulds perfectly to the shape of the upper dentition when applied and also gives full coverage of teeth with no reduction of the space when mouth is opened for surgery. It also gives better protection to the upper dentition as the gag fits perfectly on to it when applied. This, unlike gauze piece threads does not get interwined between the gaps of malaligned, prominent or crooked teeth, thereby offering superior protection. Aim: To describe the feasibility of custom fabricated teeth guard for Boyle Davis mouth gag in oral and oropharyngeal surgeries. Materials and Methods: An cross-sectional study was conducted in the Department of Ear, Nose and Throat, Mahatma Gandhi Medical College Puducherry, India, in association with Indira Gandhi Institute of Dental Sciences, kerala, India, from February 2019 to April 2019. The equipment was simple, comprising of a paste of elastomeric silicone putty which had a base and catalyst which was custom made for the patient, just minutes before application over the patient’s upper dentition and over which the Boyle Davis mouth gag was applied and then the mouth opened for surgery. Total 50 consecutive patients, in the age group of 6-18 posted for tonsillectomy, were inserted with the equipment before application of Boyle Davis (BD) gag. The ease of insertion with a score of 1-4 was recorded from the surgeon. Postoperatively, once the gag was removed along with the custom made putty, the patient’s upper dentition was examined to look for any dental injuries that might have occurred due to gag insertion. The comfort level was assessed by a targeted questionnaire over a scale of difficulty from 1-4, 1 being comfortable and 4 being difficult. Results: The mean age of the patients was 10.56 years with the mean weight of 38.55 kilograms. There were 27 males and 23 females. In all the patients, pre and perioperative period was uneventful. The ease of insertion score was 1 in all the 50 patients; there were no oral injuries and no residual side-effects due to the material used. The mean score for comfort level was 1.8. Conclusion: An indigenously made elastomeric teeth guard is extremely effective in preventing dental injuries after application of Boyle Davis mouth gags in cases of adenotonsillectomy under controlled general anaesthesia.

Objectives To assess if wearing a mouth guard impacts maximal aerobic capacity in amateur boxers. Materials and Methods A prospective crossover cohort (pilot) study was conducted to assess maximal aerobic capacity in amateur boxers using the 20 m multi stage fitness test (MSFT). Two primary outcomes measures were recorded: (1) the maximum oxygen uptake (peak VO2—mL/kg/min) and (2) distance run (meters—m). Thirteen amateur boxers completed the MSFT 7 days apart under control (no mouth guard—C) and intervention conditions (mouth guard—MG). Participants also submitted data on height, weight, type of mouth guard and Rate of Perceived Exertion (RPE) during the test. Statistics Paired T‐test. Results Mouth guard use was shown to reduce peak VO2 and distance run during the 20 m MSFT from 56.31 to 54.12 mL/kg/min and 2572 to 2380 m respectively (p

Introduction and importance Tori are benign bony outgrowths that occur in different locations along the mandible and maxilla. Their origin is still uncertain; however, various hypotheses have been put forward, including male gender or mechanical overload. Recurrence of a torus after surgical resection is rarely described, and even less rapidly after a procedure. Case presentation We present here the case of a 52-year-old patient who presented voluminous mandibular tori on the lingual side. The tori recurred very rapidly after the first resection surgery and with the same initial volume. Pathological examinations confirmed the histological type. The identified risk factors were excessive fish consumption, occlusal overload factors, and male gender. The patient then underwent a second surgery associated with a mouth guard in order to treat bruxism. There was no recurrence after one year of follow-up. Clinical discussion This case report highlights the fact that there is still a lack of understanding of the risk factors associated with torus. However, several studies have been able to understand certain genetic or dietary mechanisms in the genesis of these exostoses. Conclusion This case emphasizes the importance of mechanical overload in the recurrence of exostoses, which, coupled with dietary, gender, and ethnic factors, may be responsible for recurrence in this patient. The detection of factors associated with the risk of recurrence is a major challenge., Highlights • The various factors that cause torus are still poorly understood. • Recurrence of tori after surgery has been described only rarely, but never rapidly. • The detection of factors associated with the risk of recurrence are a major challenge, in order to avoid recidivism.

Teeth clenching during exercise is important for sports performance and health. Recently, several mouth guard (MG)-type wearable devices for exercise were studied because they do not disrupt the exercise. In this study, we developed a wearable MG device with force sensors on both sides of the maxillary first molars to monitor teeth clenching. The force sensor output increased linearly up to 70 N. In four simple occlusion tests, the trends exhibited by the outputs of the MG sensor were consistent with those of an electromyogram (EMG), and the MG device featured sufficient temporal resolution to measure the timing of teeth clenching. When the jaw moved, the MG sensor outputs depended on the sensor position. The MG sensor output from the teeth-grinding test agreed with the video-motion analysis results. It was comparatively difficult to use the EMG because it contained a significant noise level. Finally, the usefulness of the MG sensor was confirmed through an exercise tolerance test. This study indicated that the developed wearable MG device is useful for monitoring clenching timing and duration, and the degree of clenching during exercise, which can contribute to explaining the relationship between teeth clenching and sports performance.

Roberts, AH, Walden, AJ, Carter, KA, and Symons, TB. Effect of sport-specific constraints on aerobic capacity in high school field hockey players. J Strength Cond Res 36(2): 493-497, 2022-Many sports require the use of a mouth guard (MG) and carrying an object during play. Research has shown that individually these conditions can cause performance decrements; however, no research has been conducted into the effect of combining both mouth guard and stick with adolescent female field hockey players. This study aimed to determine the effects of MG and stick (STK) use on estimated aerobic capacity over the course of a season long training and competition period. Thirty-eight female high school field hockey players were separated into 2 groups: experimental (EXP-all training with MG-STK) or control (CTL-all training without MG-STK). Aerobic capacity was estimated using a multi-stage fitness test. Field hockey specific training prescribed by coaching staff was performed throughout the study, with testing at pre-, mid- and post-season. Subjects performed 2 sets of testing at each time point, first without MG-STK (WOMG-STK) and then with MG-STK. No main effect was observed in aerobic capacity estimations between groups; however, MG-STK testing reduced estimated aerobic capacity at each time point, regardless of the group (WOMG-STK: 37.4 ± 6. mL·kg-1·min-1 vs. MG-STK: 33.2 ± 4. mL·kg-1·min-1; p0.01). Chronic use of MG-STK does not seem to negatively impact estimates of aerobic capacity over the course of a season in high school field hockey players. Therefore, players should be encouraged to use MGs during all training sessions as it increases safety and familiarity with no decrement in long-term physiological performance.

Introduction Oral injuries are common traumas in combat sports due to the aggressive nature of both offense and defense. Sports mouth guards are made to reduce the risk of traumatic face and jaw injuries and concussions during sports activities. Objective The objective of this study was to determine the prevalence of oral injuries in combat sports and to examine the association between participation levels and percentage of injury occurrence. Methods One hundred and eight participants (mean age: 22.42 ± 2.162 years) who were involved in sparring events were recruited. Data were collected using a questionnaire consisting of 22 questions about the demographic profile of the athletes, their injury experience and type of injuries sustained, awareness and use of mouth guards in sports activities. Descriptive analysis, Chi-square test, and one-way analysis of variance (ANOVA) were applied for data analysis. Results Almost 77% of participants had experienced oral injuries during sports activities and nearly 90% were aware that oral injuries can be reduced by using mouth guards. In addition, 52.7% of participants complained that the mouth guard is not comfortable to use during sports activities. Findings revealed a significant moderate association between levels of participation and number of oral injuries ( p = 0.013). One-way ANOVA showed a significant mean difference in the rate of oral injury for the four levels of participation groups F (3, 104) = 6.21, p = 0.011. Post-hoc comparisons using the Bonferroni test indicated a significant mean difference between university-state levels ( p = 0.033) and university-national levels ( p = 0.028). Conclusion This study revealed that higher levels of participation in sports have a higher risk of injury. It was also found that the discomfort of using a mouth guard can be reduced if the coaches make the athletes wear proper mouth guards that follow the recommended specifications. Level of evidence IIIb; Case control study. RESUMO Introdução As lesões orais são traumas comuns nos esportes de combate, devido à natureza agressiva tanto do ataque quanto da defesa. Os protetores bucais esportivos são feitos para diminuir o risco de lesões traumáticas na face e na mandíbula; e também de concussão durante as atividades esportivas. Objetivo Este estudo teve como objetivo determinar a prevalência de lesões orais em esportes de combate e examinar a associação entre níveis de participação e a porcentagem de ocorrência de lesões. Métodos Foram recrutados cento e oito participantes (média de idade: 22,42 ± 2,162 anos) envolvidos em eventos de combate. Os dados foram coletados por meio de um questionário composto por 22 perguntas sobre o perfil demográfico dos atletas, sua experiência com lesões e tipo de lesões sofridas, conhecimento e uso de protetores bucais em atividades esportivas. A análise descritiva, o teste do qui-quadrado e a análise de variância (ANOVA) foram aplicados para análise dos dados. Resultados Quase 77% dos participantes sofreram lesões orais durante atividades esportivas e quase 90% estavam cientes de que as lesões orais podem ser reduzidas com o uso de protetores bucais. Além disso, 52,7% dos participantes reclamaram que o protetor bucal não é confortável para uso durante as atividades esportivas. Os achados revelaram associação moderada significativa entre níveis de participação e número de lesões orais (p = 0,013). A ANOVA unilateral mostrou uma diferença média significativa na taxa de lesão oral nos quatro níveis dos grupos de participação F (3, 104) = 6,21, p = 0,011. As comparações post-hoc usando o teste de Bonferroni indicaram diferença média significativa entre os níveis universitário-estadual (p = 0,033) e os níveis universitário-nacional (p = 0,028). Conclusão Este estudo revelou que níveis mais altos de participação no esporte representam maior risco de lesões. Verificou-se também que a sensação de desconforto ao usar protetor bucal pode ser reduzida se os treinadores fizerem com que os atletas usem protetores bucais adequados, que sigam as especificações recomendadas.

Modified electroconvulsive therapy (m- ECT) is a treatment for mental disease such as depressive disorder. Although a muscle relaxant is used during current application, strong occlusion occurs due to the proximity of the electrode to the temporal and masseter muscles. Although a feedback mechanism to avoid excessive occlusion occurs unconsciously, the mechanism does not work under general anesthesia. Strong occlusion may cause complications such as tooth injury, pain of the jaw, lip laceration, and bleeding of the gums. Although there was a report that the insertion of shock-absorbing materials such as gauze reduces complications, there has been no study on the effectiveness of a mouth guard ( MG) for alleviating the occlusal force during m- ECT. The present study investigated the effectiveness of MG for alleviation of the occlusal force and complications during m- ECT. An ethyl-vinyl-acetate ( EVA) MG was used as a shock-absorbing material to mitigate the strong occlusion during m- ECT to investigate the influence of MG on the occlusal force and its effectiveness. The results showed that the occlusal force was alleviated by 58 ± 22% on average using MG during m- ECT. It also helped reduce intra-oral problems such as pain and bleeding. The results suggest the effectiveness of MG for alleviating the occlusal force during m- ECT and avoiding complications due to strong occlusion. [ABSTRACT FROM AUTHOR]

BACKGROUND: NASA has been making efforts to assess the carbon dioxide (CO2) washout capability of spacesuits using a standard CO2 sampling protocol. This study established the methodology for determining the partial pressure of inspired CO2 (PIco2) in a pressurized spacesuit. We applied the methodology to characterize PIco2 for the extravehicular mobility unit (EMU).METHODS: We suggested an automated and mathematical algorithm to find the end-tidal CO2 and the end of inspiration. We provided objective and standardized guidelines to identify acceptable breath traces, which are essential to accurate and reproducible calculation of the in-suit inhaled and exhaled partial pressure of CO2 (Pco2). The mouth guard-based method for measurement of inhaled and exhaled dry-gas Pco2 was described. We calculated all individual concentrations of PIco2 inhaled by 19 healthy subjects classified into 3 fitness groups. The transcutaneous Pco2 was monitored as a secondary measure to validate washout performance.RESULTS: Mean and standard deviation values for the data collection performance and the CO2 metrics were presented (e.g., minimum time weighted average Pco2 at suited workloads of resting, 1000, 2000, and 3000 (BTU h1) were 4.75 1.03, 8.09 1.39, 11.39 1.26, and 14.36 1.29 (mmHg s1). All CO2 metrics had a statistically significant association and all positive slopes with increasing metabolic rate. No significant differences in CO2 metrics were found between the three fitness groups.DISCUSSION: A standardized and automated methodology to calculate PIco2 exposure level is presented and applied to characterize CO2 washout in the EMU. The EMU has been operated successfully in over 400 extravehicular activities (EVAs) and is considered to provide acceptable CO2 washout performance. Results provide a basis for establishing verifiable Pco2 requirements for current and future EVA spacesuits.Kim KJ, Bekdash OS, Norcross JR, Conkin J, Garbino A, Fricker J, Young M, Abercromby AFJ.

- Abstract
Background: We present early-stage in vitro evidence supporting the hypothesis that 2-3 mm lead plaques used as shielding in prosthesis for the radiotherapy in head-and-neck cancer patients help reduce deposit dose in healthy or at risk organs. Purpose: To test the effect of lead in reducing therapeutic radiation. Methods: In vitro tests were performed with two 1 mm x 5 cm x 5 cm lead plates on a Gafchromic RQTA2 "10 x 10" chromic film. 6 MeV energy doses of 192 cGy applied with a linear accelerator as a fraction of applicable doses of teletherapy to test contact. Likewise, 168 MeV Iridium 192 (brachytherapy) were used for a 300 cGy dosis under a cover of solid water (2 cm thick polymer with the same density as water). Similar tests were performed without the lead protection in both cases (open field) as a control. Results: The density readings of the films showed, for the treatment with 2 mm lead Iridium 192, an increased difference of radiation of 7.25% compared to the open field. The treatment with linear accelerator with 6 MeV energy and 2 mm lead increased 16.25% compared to the open field. [ABSTRACT FROM AUTHOR]

The aim of this study was to analyze the influence of orthodontic bracket type (metallic or ceramic) and mouthguard on biomechanical response during impact. Two-dimensional plane-strain models of a patient with increased positive overjet of the maxillary central incisor was created based on a CT scan, simulating the periodontal ligament, bone support, gingival tissue, orthodontic brackets (metallic or ceramic) and mouthguard. A nonlinear dynamic impact finite element analysis was performed in which a steel object hit the model at 1 m/s. Stress distributions (Von Mises and Modified Von Mises) and strain were evaluated. Stress distributions were affected by the bracket presence and type. Models with metallic and ceramic bracket had higher stresses over a larger buccal enamel impact area. Models with ceramic brackets generated higher stresses than the metallic brackets. Mouthguards reduced the stress and strain values regardless of bracket type. Mouthguard shock absorption were 88.37% and 89.27% for the metallic and ceramic bracket, respectively. Orthodontic bracket presence and type influenced the stress and strain generated during an impact. Ceramic brackets generated higher stresses than metallic brackets. Mouthguards substantially reduced impact stress and strain peaks, regardless of bracket type.

The occurrence and causes of oral and dental injuries in a young Israeli population during childhood and adolescence were evaluated, as well as participants’ awareness of using protective devices, such as mouth guards, during sporting activities. The survey consisted of 427 young adults, aged 18–21 years. A questionnaire was distributed relating to past oral and dental injuries over their lifetime; type of sporting activity practiced, specifying time, place and cause of injury; and use and awareness of protective devices. Participants who reported to be injured were asked to report the type of their injury, treatment provided, and satisfaction with the results. The total number of dental and oral injuries was 133, affecting 31.1% of the participants, in which 72 (16.9%) suffered dental injuries, mostly because of falls (64%), followed by sporting activities (23.2%), street-fights (7.2%), and car accidents (5.6%). Injuries occurred at school in 36.5% of cases and at home in 23.8% of cases. The most frequently reported injury was laceration (47.3%) followed by tooth fracture (41.9%). Of the 427 participants, 239 (56%) were active in at least one type of sport. Only 22.6% were aware of protective devices, e.g. mouth guards, and only 2.8% actually used these devices. These results show the high risk of potential dental and oral injury during childhood and adolescence, a lack of knowledge regarding the benefits of mouth guards and their limited use. Increased awareness of protective measures and devices, and their actual use should be encouraged with public health education. [ABSTRACT FROM AUTHOR]

Among the various orofacial characteristics related to this syndrome, the following are pointed out, difficulty with sucking, tongue malformation, mandibular hypoplasia, saliva drooling, arched palate and micrognathia. In spite of the diversity of oral features described for these patients, self-inflicted oral trauma has not yet been reported. Therefore, the purposes of the present report were to describe an unusual case of a baby with Moebius syndrome who had a parafunctional habit that resulted in a persistent traumatic lesion of the lower lip, and discuss the treatment performed.

The main objectiveof the sport is to provide well-being to the practitioner, but in many cases its integrity is compromised bylack of care and protection, and in order to protect the oral cavity from future trauma, it is recommendedto wear mouth guards during the practice of Because it has already been proven that it is capable ofsignificantly reducing the chances of dental trauma. The mouth guard is a rigid yet flexible material, whichfits into the teeth and when used properly, will exert its valuable function. The dentist should be aware ofhis / her sports patients, informing them of the use of mouth guards and encouraging them to use them.This literature review will highlight the importance of the use of mouth guards against dental traumatism,its classification and its way of making.

Mouth guards protect against orofacial and dental injuries in sports. However, special fitted dental splints have been claimed to improve strength and speed and, therefore, to enhance athletic performance.Purpose:To test the effects of a neuromuscular fitted dental splint in comparison with a habitual verticalizing splint and a no-splint condition on cycling sprint performance in the Wingate Anaerobic Test (WAnT).Methods:Twenty-three men (26.0 ± 2.0 y, 1.82 ± 0.06 m, 79.4 ± 7.7 kg) performed 3 WAnTs, 1 with the neuromuscular fitted splint, 1 with a habitual verticalized dental splint of the same height and material, and 1 under control conditions without any mouth guard, in randomized order separated by 1 wk.Results:No differences between any splint conditions were found in any aspect of WAnT performance (time to peak power, peak power, minimum power, power drop, and average power). Moderate to nearly perfect correlations between all splint conditions in all WAnT outcomes with coefficients of variation between 1.3% and 6.6% were found.Conclusions:Irrespective of habitual verticalization or myocentric positioning, dental splints have no effects on any aspect of WAnT performance. Results are comparable to those of test–retest experiments.

Mouth guards are considered an essential part of equipment for athletes participating in contact sports. The purpose of this study was to evaluate the effect of custom-made mouth guards on the ventilatory gas exchange effects of taekwondo athletes. The subjects were 22 elite athletes aged between 14 and 17 years. To determine the effect of mouth guard use during exercise, oxygen consumption (VO2) was measured with a portable gas analysis system while an exercise tolerance test with a shuttle run test protocol was performed. Values with and without mouth guard were compared. Wilcoxon ranks test was used for the statistical analysis. The results show that wearing mouth guards has no significant effect on maximal oxygen uptake (VO2max), minute ventilation (VE), tidal volume (VT) and respiratory exchange ratio (RER) while performing maximal exercise ( P > 0.05). In conclusion, taekwondo athletes can use custom-made mouth guards without negative effects on their aerobic performance capacity. [ABSTRACT FROM AUTHOR]
