Prevalence of dentofacial injuries among combat sports practitioners: A systematic review and meta-analysis

Oro-dental trauma burden and mouthguard usage among contact sports players: A call for sports dentistry initiatives in Sri Lanka

BACKGROUND/AIM

Contact sports-related oro-dental trauma contributes to a significant proportion of sports injuries among school children. Oro-dental trauma imposes a detrimental impact on the oral health-related quality of life. However, the burden of oro-dental trauma among contact sports players and their practices of mouthguards remains a research gap in Sri Lanka. The current study bridges that while providing evidence for contextual changes such as initiating sports dentistry.

MATERIALS AND METHODS

The study was conducted among 1340 adolescent contact sports players in Colombo district, Sri Lanka; 63.1% males and 36.9% females (age 13-18), who were enrolled in football, rugby, hockey, boxing, basketball, and martial arts in the school setting. A checklist was administered to obtain demographic information, sports practices, and the use of mouthguards. An oral examination was conducted for those who experienced oro-dental trauma during the last 12 months.

RESULTS

Self-reported oro-dental trauma pooled prevalence of the contact sports players was 35.9% (95% CI = 33.3-38.5), with males' preponderance. Dental trauma was present in 23.8% (n = 319), while 15.8% were uncomplicated and 8% were complicated. Soft tissue injuries were present in 12.1% (n = 162). Oro dental trauma (ODT) was highly prevalent among boxing, rugby, and hockey players. Only 20.8% (n = 279) of players used mouthguards. However, 91.0% (n = 254) of them were using ready-made mouthguards. Mouthguard use and the type of mouthguard showed statistically significant associations across the type of oro-dental trauma among contact sports players.

CONCLUSIONS

Contact sports-related oro-dental trauma prevalence is as high as 35.9% among Colombo district school children in Sri Lanka. However, their level of mouthguard usage is shallow at 20.8%. Further research is necessary to investigate the reasons behind this, and national guidelines should be developed to prevent and manage sports-related accidental injuries.

Epidemiology of Injuries and Their Implications in Jiu-Jitsu Practitioners: An Integrative Systematic Review

Objective  To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods  Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results  Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion  There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport.

Care of The Older Fighter: Position Statement of the Association of Ringside Physicians

Older Fighters are defined as combat sports athletes older than 35 years, based on heightened medical risks and historical classification. Age-related changes to the neurological, cardiopulmonary, endocrinological, thermoregulatory, osmoregulatory, and musculoskeletal systems increase these athletes' risks for injury and may prolong their recovery. These age-related risks warrant special considerations for competition, licensure, prefight medical clearance, in-fight supervision, post-fight examination, and counseling regarding training practices and retirement from combat sports. Neurological considerations include increased risk of intracranial lesions, intracranial hemorrhage, and sequelae from traumatic brain injury (TBI), warranting more comprehensive neurological evaluation and neuroimaging. Increased risk of myocardial ischemia and infarction warrant careful assessment of cardiac risk factors and scrutiny of cardiovascular fitness. Older fighters may take longer time to recover from musculoskeletal injury; post-injury clearance should be individualized.

Comparative analysis of dental trauma in contact and non-contact sports: A systematic review

Dental traumas in sports are common and have physical, social, psychological, and economic impacts. The aim of this study was to determine, through a systematic review, the prevalence of dental trauma in contact and non-contact sports. This review was submitted to PROSPERO (CRD42023421206). Included studies addressed the prevalence of dental trauma in young athletes and adults above 18 years, excluding reviews, editorials, symposiums, or those evaluating athletes under 18 years. A literature search was conducted using the databases PubMed, Web of Science, Scopus, Embase, LIVIVO, SPORTDiscus, Dentistry & Oral Sciences Source (via EBSCO), and Lilacs and BBO, as well as gray literature. Bias risk was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist. Data were synthesized considering study characteristics, population, sport, and outcomes. R Statistics software was used for all meta-analyses. A total of 1707 articles were identified. After applying eligibility criteria, eight were selected. Three studies, not previously observed, were later added after reading four systematic reviews on a similar topic. Fourteen contact sports and five non-contact sports were analyzed. The prevalence of dental trauma was 11.38% in contact sports and 5.24% in non-contact sports. Regardless of the type of sport, athletes face risks of dental trauma, with contact sports showing higher prevalence. The use of mouthguards is essential across all contact and non-contact sports as a preventive measure.

Prevalence of dental, oral, and maxillofacial traumatic injuries among domestic violence victims: A systematic review and meta-analysis

BACKGROUND/AIMS

Domestic violence (DV) encompasses a series of abusive behaviors, perpetrated in a family environment, against individuals of all ages and genders. Injuries to the head, neck, and face are frequent findings among victims of abuse, negatively impacting their quality of life. Although oral and maxillofacial injuries (OMFI) and traumatic dental injuries (TDI) are commonly diagnosed among DV victims, their prevalence is still unknown. This systematic review was aimed to assess the prevalence of OMFI and TDI among victims of DV.

METHODS

The protocol of the review was registered in PROSPERO (CRD42023424235). Literature searches were performed in eight electronic databases, up to August 7th, 2023. Observational studies published in the Latin-roman alphabet and reporting the prevalence of OMFI and/or TDI were included. The Joanna Briggs Institute's critical appraisal tool, checklist for prevalence studies, was used for quality assessment. Results were presented as qualitative and quantitative syntheses.

RESULTS

Seventeen studies, totaling 12,375 victims of domestic violence, were included. Meta-analyses showed an overall prevalence of 29% (95% CI: 15%-48%, I2  = 99%) and 4% (95% CI: 1%-10%, I2  = 98%) for OMFI and TDI, respectively. Higher pooled prevalence for OMFI (41%, 95% CI: 13%-46%, I2  = 99%) was demonstrated in samples with only women. OMFI was less prevalent (20%) among DV victims under 18, while TDI was lower among adults (1%). Hospital samples presented higher pooled prevalence of OMFI (32%), and forensic data from fatal victims presented higher prevalence of TDI (8%).

CONCLUSION

The overall prevalence of OMFI and TDI in DV victims was 29% and 4%, respectively. Women victims of DV presented higher rates of OFMI (41%) and TDI (6%).

Prevalence of adverse events in pronated intubated adult COVID-19 patients: A systematic review with meta-analysis

AIM

To present the pooled estimated prevalence of adverse events in pronated intubated adult COVID-19 patients.

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

This study used the Cochrane Library, CINAHL, Embase, LILACS, Livivo, PubMed, Scopus, and Web of Science databases as data sources.

METHODS

The studies were meta-analysed using JAMOVI 1.6.15 software. A random-effects model was used to identify the global prevalence of adverse events, confidence intervals and the heterogeneity data. Risk of bias was assessed using the Joanna Briggs Institute tool, and the certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Of the 7904 studies identified, 169 were included for full reading, and 10 were included in the review. The most prevalent adverse events were pressure injuries (59%), haemodynamic instability (23%), death (17%) and device loss or traction (9%).

CONCLUSION

The most prevalent adverse events in mechanically ventilated pronated patients with COVID-19 are pressure injuries, presence of haemodynamic instability, death and device loss or traction.

IMPLICATIONS FOR THE PATIENT CARE

The evidence identified in this review can help improve the quality and safety of patient care by helping to design care protocols to avoid the development of adverse events that can cause permanent sequelae in these patients.

IMPACT

This systematic review addressed the adverse events related to prone position in intubated adult COVID-19 patients. We identified that the most prevalent adverse events in these patients were pressure injuries, haemodynamic instability, device loss or traction and death. The results of this review may influence the clinical practice of nurses who work in intensive care units and, consequently, the nursing care provided not only to COVID-19 patients but for all intubated patients due to other reasons in intensive care units.

REPORTING METHOD

This systematic review adhered to the PRISMA reporting guideline.

PATIENT OR PUBLIC CONTRIBUTION

As this is a systematic review, we analysed data from primary studies conducted by many researchers. Thus, there was no patient or public contribution in this review.

A systematic review of the added value of perioperative pain neuroscience education

OBJECTIVE

To identify and summarize evidence about the benefits of perioperative pain neuroscience education (PNE) on pain-related and psychosocial outcomes.

METHODS

Included were reports written in English that carried out PNE or its synonyms; perioperative period; aged ≥ 18 years; interventional studies and observational studies. Secondary studies, conference abstracts, and editorials were excluded. There was no time limitation.

INFORMATION SOURCES

PubMed, Virtual Health Library, Cochrane Library, and Science Direct. Search: June 20th 2023. The risk of bias was assessed using the Joanna Briggs Institute checklists, and synthesis followed the recommendations of the Synthesis Without Meta-analysis (SWiM) guideline. Register: Center for Open Science website (10.17605/OSF.IO/ZTNEJ).

RESULTS

The sample consisted of 18 reports. For pain outcomes, it was not possible to attribute PNE benefits because ten reports found improvements in both intervention and control groups. For psychosocial outcomes, fourteen reports found benefits for PNE groups. All the analyzed reports showed low risk of bias.

CONCLUSION

PNE had additional benefits beyond those obtained with conventional treatment for psychosocial outcomes.

PRACTICAL IMPLICATIONS

Due to the lack of evidence, it was not possible to indicate the clinical use of PNE. It is suggested that further studies are needed aimed at clarifying the possible benefits.

A suggested universal protocol for dental examination in sports

The athletes of any sport and level submit their bodies to constant exercise. Any given pathology can increase the risk of injury, illness, or even reduced performance. The medical examination is valuable in diagnosing existing health problems and preventing medical issues that might compromise the athlete's overall health when exercising. The stomatognathic system is not an exemption, as oral pathologies, including dental caries and periodontal diseases, are found in high incidence in sports. The need for accurate and detailed dental examination in sports leaded dentists from the European Association for Sports Dentistry and the Academy for Sports Dentistry to elaborate a universal dental examination in sports protocol that can record the overall oral health of the athlete, including the teeth, periodontium, and musculoskeletal screening, for all athletes. The outcome of this stomatognathic examination allows sports physicians and professionals other than dentists to have a complete image of the individual oral health condition of any given athlete, and it allows the dentists to efficiently screen and prevent pathologies, as well as to advise on the eligibility to practice sports from the oral health perspective.

Development and validation of a novel index to assess the perceived impact of sports-related oro-dental trauma among adolescents: findings from Sri Lanka

BACKGROUND

Sports-related oro- dental trauma, such as tooth fracture, displacement, mobility, and avulsion, cause significant concern among adolescent players due to detrimental impacts. The current study aims to develop, validate and assess the reliability of a simple index as a questionnaire to assess the impact of sports-related oro-dental trauma both untreated and treated, among adolescent school children in Sri Lanka.

METHODS

AODTII, an adolescent oro-dental trauma impact index, was developed and validated using a mixed-method approach. Items for the index were generated by quantitative as well as qualitative analysis of the results from Oral Health-Related Quality of Life Questionnaires, personnel interviews with experts and focus group discussions with adolescents. Principal component analysis and Exploratory factor analysis were used to create the index. The index was validated in the Sinhala language, and the reliability of the index was assessed using a separate sample in the school context in the Colombo district.

RESULTS

The initial list of 28 items was reduced to 12 by the Principal Component Analysis. Exploratory Factor Analysis categorised the variables into four latent constructs; physical impact, psychosocial effect influenced by peer pressure, the impact of oral health care and the impact caused due to unmet dental trauma treatment need. The cut-off values of the AODTII were based on PCA. The index achieved the Content Validity Ratio of 88.33. The construct validity was assessed with confirmatory factor analysis by developing a structural equation model. It obtained good model fit indices of RMSEA value of 0.067, SRMR of 0.076, CFI of 0.911 and the Goodness of Fit index of 0.95. The homogeneity was ensured with convergent and discriminant validity. The Cronbach's alpha value was 0.768, ensuring reliability. The index assesses the level of impact due to oro- dental trauma and identifies whether the adolescents perceive it significantly or not.

CONCLUSION

Twelve-item AODTII emerged as a reliable and valid tool to assess the perceived impact of untreated and treated sports-related oro- dental trauma on Sri Lankan adolescents with implications for its use in other populations. Further research is required to improve the translational value of AODTII. Moreover, the tool is potential as a patient-centred communication tool, clinical adjunct, advocacy tool and a useful OHRQoL index. However, it is needed to be supported end-users' feedback.

Quantitative text analysis of the mechanisms of tooth injury: Analysis of accidents in five sports that occurred in 15 years under school control

BACKGROUND/AIM

Dental trauma may occur in school settings and it can impact patients' quality of life. Analysis of the occurrences of dental trauma is essential in identifying preventive methods. There are numerous reports of such accidents but most are quantitative analyses with limited data. The aim of this study was to extract information on the mechanisms of injuries that leads to prevention by performing a qualitative analysis of the occurrence of dental trauma.

MATERIAL AND METHODS

After screening 7684 cases of dental injuries that occured in schools and were reported to the Japan Sports Council between 2005 and 2020, 533 detailed descriptions of injuries that occurred during sports were included. Quantitative text analysis was performed on the target data by performing statistical analysis, extracting frequently used words, and creating a co-occurrence network. Injury mechanisms were evaluated based on appearance of words.

RESULTS

Dental injuries occurred frequently in five sports included in the survey. They were in order of decreasing frequency: baseball, basketball, soccer, volleyball, and rugby. Males were injured more often in all sports other than volleyball. The number of accidents increased in all sports among high school students. The frequent word list and co-occurrence network were different for each sport. This allowed typical accident occurrence mechanisms to be extracted for these five sports.

CONCLUSIONS

Typical accident occurrence mechanisms were extracted from quantitative text analysis targeting free texts on the occurrence of accidents for five sports. Quantitative text analysis is useful for the evaluation of accident cases, which may aid in accident prevention.

Impacts of educational interventions on the knowledge of prevention and emergency management of traumatic dental injuries in 11-17-year-old martial arts athletes: a randomized controlled trial

PURPOSE

We compared the effect of an educational pamphlet and a mobile application regarding prevention and emergency management of sport-related traumatic dental injuries (TDIs) on knowledge and self-reported preventive practice of 11-17-year-old Karate and Taekwondo athletes.

METHODS

Participants were invited through an online link published by the Public Relations of the corresponding federations. They completed an anonymous questionnaire consisting of demographics, self-reported experience of TDIs, knowledge of emergency management of TDIs, self-reported preventive practice of TDIs, and the reason for not using mouthguard. The respondents were randomly allocated to pamphlet or mobile application group with the same content. Three months after the intervention, the questionnaire was completed by the athletes again. Repeated measures ANOVA and a linear regression model served for statistical analysis.

RESULTS

In pamphlet group, 51 athletes and in mobile application group 57 athletes completed both baseline and follow-up questionnaires. At baseline, the mean score was 1.98 ± 1.20 and 1.82 ± 1.24 (out of 7) for the knowledge and 3.70 ± 1.64 and 3.33 ± 1.95 (out of 7) for practice in the pamphlet and application group, respectively. In 3-month follow-up, the mean score of knowledge and self-reported practice was significantly higher compared to baseline in both groups (p < 0.001) with no statistically significant difference between the two groups (p = 0.83 and p = 0.58, respectively). Most of the athletes were very satisfied or satisfied with both types of the educational intervention.

CONCLUSION

Both pamphlet and mobile application seem to be useful to improve awareness and practice regarding TDI prevention in adolescent athletes.

Incidence Rates and Pathology Types of Boxing-Specific Injuries: A Systematic Review and Meta-analysis of Epidemiology Studies in the 21st Century

Background

To the best of our knowledge, an evidence-based investigation into 21st-century boxing-specific injury rates and types has yet to be performed.

Purpose

To provide an overview and quantitative synthesis of the incidence rates (IRs) and pathological categorizations of boxing-specific injuries in the 21st century.

Study Design

Systematic review; Level of evidence, 3.

Methods

Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched literature published from January 2000 to November 2021 in PubMed and the Cochrane Library systematically for qualifying epidemiology studies of organized boxing activities across the world. Two independent reviewers completed the literature review, data extraction, and quality assessment. The IRs of injuries per 1000 boxers (IR_N), per 1000 competition exposures (IR_E), and per 1000 minutes of competition (IR_C) or training (IR_T) were subsequently calculated. Single-arm meta-analyses were performed for the subgroups of different types of boxing. Sample size weighted means were calculated using a random-effects model in all studies with 95% CIs.

Results

Out of an initial 9584 articles, 14 studies were included, with most (11/14) having a moderate level of quality. The pooled IR_N in overall injuries was 223.9 (95% CI, 157.5-290.4), the IR_E was 233.3 (95% CI, 161.3-305.2), and the IR_C was 13.0 (95% CI, 8.9-17.1). In professional boxing, the IR_N (399.8), IR_E (379.8), and IR_C (23.9) were all significantly higher than in the amateur and female groups. The IR_E (76.6 vs 250.6; P < .000) and IR_C (9.2 vs 15.4; P < .000) in amateur boxing were significantly lower in studies between 2010 and 2019 than in earlier studies. For pathology categorization, the pooled frequencies were 12.3% (95% CI, 8.7%-15.9%) for concussion, 21.4% (95% CI, 14.1%-28.6%) for skin laceration, 30.2% (95% CI, 22.1%-38.2%) for soft tissue contusion, 15.3% (95% CI, 7.7%-22.9%) for sprain and muscle/ligament injury, and 11.4% (95% CI, 2.7%-20.1%) for fracture.

Conclusion

IRs of injury remain high in professional boxing, although they have decreased in the past 10 years in amateur boxing. Soft tissue contusion was the most common injury type. Better exposure measurements and epidemiologic indicators should be applied in future studies.

Head Trauma Exposure in Mixed Martial Arts

Combat sports training involves a high risk of head injury. Previously published research on head trauma exposure in MMA evaluated only the knockouts (KO), without calculating all head strikes. The aim of the research was to evaluate the total head trauma exposure during MMA competitions among male and female fighters. Two thousand four hundred and eighty-eight MMA fights from all numbered UFC events between 2000 and 2021 were analyzed. A database containing the results from officially published scorecards with information such as the outcome of a fight, its duration, number of strikes (significant and total amount of hits) depending on location and knockdowns was created. Additional video verification of the knockout technique was carried out. The athletes received an average of 2.41 significant head strikes out of a total of 6.30 head strikes per minute. Head strikes were more common in female fights than in male. Women executed more total and significant head strikes per minute than men. Head trauma caused the ending of 31.6% of all fights-more often in male fights (32.2%) than female (23.1%). It was the most common cause of knockouts-88.1%. Professional fights in mixed martial arts involve high exposure to head trauma. A careful evaluation of the risk involved in training in such a discipline is necessary to provide adequate prevention methods.

External Apical Root Resorption in Orthodontic Patients Who Practice Combat Sports: A Case-Control Observational Pilot Study

Orthodontic treatment could lead to undesirable effects such as external apical root resorption (EARR). Moreover, trauma to both the face and teeth can predispose to EARR. On the other hand, the practice of combat sports results in increased maxillofacial injuries. Consequently, our objective was to determine if there is a statistically significant difference in the EARR of the patients undergoing fixed orthodontic treatment who practice combat sports and controls. Our null hypothesis was that there is no difference in the EARR between patients undergoing orthodontic treatment who practice combat sports and the patients under the same treatment that do not practice combat sports. An observational, descriptive, and prospective case-control pilot study was designed. The exposed group consisted of patients that practice combat sports. Whereas the control group was conformed of patients that do not practice combat sports without a previous history of facial trauma and without face trauma during the orthodontic treatment. EARR of the maxillary and mandibular anterior teeth was measured using cone-beam computed tomography (CBCT). The CBCT scans were obtained from all patients prior to the beginning of the orthodontic treatment and 1 year later. At the end of the follow-up for the maxillary right central and lateral incisors of the exposed group, the EARR was significantly higher than the homologous teeth of the control group (p < 0.05). As a consequence, the patients treated orthodontically who practice combat sports could be more susceptible to EARR.

Orofacial conditions and oral health behavior of young athletes - a comparison of amateur and competitive sports

PURPOSE

This retrospective cross-sectional study aimed to evaluate oral health status (dental, periodontal and functional) and oral health behavior in young German athletes including the comparison of competitive (CA) and amateur sports (AA).

METHODS

Data of CA (German national teams, perspective and youth squads) and AA aged between 18 and 30 years with an available oral examination in 2019 were included. Clinical examination: caries experience (DMF-T), non-carious wear (erosion, BEWE), partially erupted wisdom teeth, gingival inflammation (PBI), plaque index, periodontal screening (PSI), and temporomandibular dysfunction (TMD) screening. Questionnaires: oral health behavior, periodontal symptoms.

RESULTS

88 CA (w = 51 %, 20.6 ± 3.5 years) of endurance sports and 57 AA (w = 51%, 22.2 ± 2.1 years) were included. DMF-T was comparable (CA: 2.7 ± 2.2, AA: 2.3 ± 2.2; p = 0.275) with more D-T in CA (0.6 ± 1.0) than AA (0.3 ± 0.7; p = 0.046; caries prevalence: CA: 34 %, AA: 19 %; p = 0.06). Both groups had low severity of erosion (BEWE about 3.5). CA had more positive TMD screenings (43 % vs. 25 %; p = 0.014). In both groups, all athletes showed signs of gingival inflammation, but on average of low severity (PBI < 1). More CA needed complex periodontal treatment than AA (maximum PSI = 3 in 40% vs. 12%; p < 0.001). Oral health behavior was comparable (daily tooth brushing, regular dental check-ups in > 70%).

CONCLUSIONS

Young German athletes (CA and AA) generally showed signs of gingival inflammation and needed to improve their oral health behavior. CA showed slightly increased oral findings (more D-T, periodontal and TMD screening findings) than AA, but similar oral health behavior. This may imply an increased dental care need in competitive sports.

Use of technology for self-care in surgical wound infection surveillance: integrative review

ABSTRACT Objectives: to synthesize knowledge about technology for self-care in surgical wound infection surveillance. Methods: integrative review conducted in CINAHL, Embase, LILACS, PubMed, Scopus and Web of Science databases with the descriptors “surgical wound infection” and “self-care”, in addition to manual search in the references of the included studies. The selection and evaluation of the methodological quality of the studies and data collection were performed by two independent reviewers; conflicts were resolved by a third reviewer. Results: nine primary studies were included, published between 2011 and 2019. Six are cross-sectional, two are randomized clinical trials, and one is a case report. Mobile, text messaging, and imaging applications, computer software, assessments, and data storage capacity stand out. Conclusions: the technologies identified for self-care in surgical wound infection surveillance were the creation and use of mHealth and the use of health apps on mobile devices. Effective technologies in surveillance of surgical wound infection that enable rapprochement with the healthcare team, encourage a greater number of surgical wound assessments, enhance self-care actions, and decrease patient anxiety. Technology is also a monitored and recorded form of patient care, one of the main axes of infection surveillance.

Useful design of custom-made mouthguard for athletes undergoing orthodontic treatment with brackets and wires

Background/purpose

Custom-made mouthguards (MGs) are strongly recommended for athletes during sports activities to prevent dental injuries. Athletes undergoing orthodontic treatment and wearing brackets require specially designed MGs for better protection and to create more space that will not hinder the planned orthodontic tooth movement. The purpose of this study was to fabricate effective, specially designed, custom-made MGs for patients or athletes with ongoing orthodontic treatment and to evaluate the shock absorption abilities of these MGs by an in vitro comparison of three different designs.

Materials and methods

Three different types of specially designed, double-layered MGs, (i) creating inter bracket space inside the MG, (ii) embedding silicon wax inside the MG, and (iii) creating a buffer space with additional hard insertion, were fabricated from a simulated bracket attached model. Impact test was performed using a free-falling object on a vertical rod, and the strain-gauge system was used to assess the strain on the dentition with the MGs for the comparison of the shock absorption abilities of the three types. Analysis of variance at a significance level of 5% and multiple comparisons were performed for statistical analysis.

Results

The strains on the dentition with the MG creating buffer space with hard insertion were significantly lower than those with the other two types of MG (P < 0.001).

Conclusion

Insertion of a hard material and ensuring buffer space between the MG and the teeth and/or appliance was more effective than other methods of fabricating custom-made MGs to prevent sports-related traumatic dental injuries in athletes undergoing orthodontic treatment.

Prevalence of dental trauma in Brazilian children and adolescents: a systematic review and meta-analysis

This study aimed to investigate the prevalence of dental trauma in Brazilian children and adolescents. A systematic review was conducted considering eight databases: MEDLINE (via PubMed), LILACS, BBO, Scopus, Embase, Web of Science, Open Access Theses and Dissertations, and OpenThesis. Only prevalence studies that used a probabilistic sampling method were included, without restriction on year or language of publication. The JBI critical appraisal tools for prevalence studies were used to assess the individual risk of bias. The individual studies were combined in the meta-analysis using the random-effects model. The heterogeneity between the studies was analyzed by Cochran's Q and the I-square statistics. A meta-regression analysis was performed to evaluate the sources of heterogeneity. The GRADE approach assessed the certainty of evidence across included studies. The search resulted in 2,069 records, of which 36 were included in the study. The eligible studies were published from 2000 to 2021, with a total sample of 40,194 children and adolescents. Most studies (75%) had a low risk of bias. In permanent teeth, the prevalence of dental trauma was 21% (95%CI: 16.0; 26.0) and in deciduous teeth; 35% (95%CI: 26.0; 44.0). The prevalence of dental trauma among boys was higher than among girls for both dentitions. Based on a low certainty, the prevalence of traumatic dental injuries in Brazilian children and adolescents is higher than that found worldwide both in deciduous and permanent teeth. Also, the prevalence of dental trauma among boys is higher than among girls.

Prevalence of anterior open bite in children and adolescents: a systematic review and meta-analysis

PURPOSE

Anterior open bite is defined by the lack of incisal contact between the teeth in centric relation. The aim of this study was to determine the prevalence of anterior open in children and adolescents.

METHODS

This systematic review included a search in the databases: PubMed, Scopus, Web of Science, LILACS, Google Scholar, and ProQuest. The acronym PECOS was considered: (P) children and adolescents, (E) presence of anterior open bite, (C) not applicable, (O) prevalence, and (S) observational studies. The risk of bias assessment was carried out using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The prevalence meta-analyses were performed using MedCalc^® software. The certainty of the evidence was determined with the GRADE approach.

RESULTS

26 studies were included. Eleven studies were judged at low, seven at moderate, and eight at high risk of bias. The overall prevalence of anterior open bite was 16.52% (95% CI 12.34-21.17) in children and adolescents. The prevalence was 19.38% (95% CI 13.77-25.69) in South America. The prevalence of anterior open bite was 22.67% (95% CI 16.56-29.43) among females and 16.99% (95% CI 11.77-22.94) among males. The prevalence of anterior open bite was 18.84% (95% CI 13.88-24.38) in the primary dentition, and 14.26% (95% CI 7.67-22.46) in the mixed dentition. The overall certainty of the evidence was very low.

CONCLUSION

The overall prevalence of anterior open bite was 16.52% in children and adolescents aged 2-16 years. Giving the limitations of a prevalence meta-analysis, the extrapolation of the results should be cautious.

Postoperative complications in adult patients undergoing surgery with confirmed infection by SARS-CoV-2: An integrative review

Objective:

to analyze the evidence available in the literature about postoperative complications in adult patients undergoing surgical procedures with confirmed infection by SARS-CoV-2.

Method:

an integrative literature review conducted in the CINAHL, EMBASE, LILACS, PubMed, Scopus and Web of Science databases, as well as in the gray literature. The references identified were exported to the EndNote manager and, subsequently, to the Rayyan web application for study selection. The stages of sampling, categorization of studies, evaluation of the studies included, interpretation of the results and knowledge synthesis were performed by two reviewers independently and in a masked manner. The data were analyzed descriptively.

Results:

of the 247 articles identified, 15 were selected to comprise this review. The prevalent postoperative complications in patients infected with SARS-CoV-2 were the following: cough, dyspnea and hypoxia, need for invasive mechanical ventilation or not, admission to the intensive care unit and death.

Conclusion:

the most reported postoperative complications in the studies evaluated were respiratory-related, followed by cardiovascular complications. The importance of preoperative screening for COVID-19 is highlighted, as well as of the monitoring and tracking of confirmed cases in the postoperative period, as these actions exert an impact on reducing the occurrence of complications related to SARS-CoV-2.

The role of teledentistry in oral cancer patients during the COVID-19 pandemic: an integrative literature review

OBJECTIVES

This integrative review aimed to assess the benefits of the use of teledentistry for patients undergoing treatment of oral and head and neck cancer during the COVID-19 pandemic.

MATERIALS AND METHODS

We searched in PubMed, Cochrane, Scopus, Web of Science, Lilacs, Embase, Open Grey, Google Scholar, and Jstor databases for studies referring to the management, control, and assistance, through teledentistry, to patients with oral and head and neck cancer during the COVID-19 pandemic.

RESULTS

We found 356 references in the databases, 209 after duplicates removal, 23 met criteria for full-text reading, and 11 studies were included for qualitative synthesis, in four categories: virtual visits, use of remote technology, patient's satisfaction, multidisciplinary approach in teledentistry. We found that 78% of patients currently preferred teledentistry; 92% of patients would recommend the use of video consultation to other patients. The continuity of dental care, the reduction of patient visits to the hospital, the reduction of the risk of infection with the coronavirus, and limitation of face-to-face consultations to protect health professionals are benefits that reinforce the use of teledentistry by health institutions. Two studies showed patients' satisfaction with the use of teledentistry in monitoring cancer patients and showed an improvement in quality of life.

CONCLUSIONS

The teledentistry, as a remote technology for monitoring patients with oral and head and neck cancer, is well accepted by patients in preliminary studies. Although these studies pointed out some benefits of using remote technologies for the care of cancer patients, further robust scientific evidence is still needed in this regard.

Prevalence, Patterns, and Characteristics of Eye Injuries in Professional Mixed Martial Arts

Purpose

To describe the frequency and type of eye injuries in fighters in mixed martial arts (MMA) competition.

Methods

Fight result data were collected from the Nevada Athletic Commission database from 2001 to 2020. Any fighters in a professional mixed martial arts (MMA) contest with an eye injury were included. Main outcome measures included frequency and rate of eye injuries per fight and the types of eye injuries. Secondary outcome measures were gender, laterality, decision type, and length of no-contact recommended.

Results

Of the 256 MMA events in the database, 187 events (73.3%) had at least one eye injury. Of a total 2208 fights at these events, there were 363 fighters who sustained 369 eye injuries, with the yearly rate of eye injuries per 100 fighters ranging from 2.56 to 12.22. The most common injuries were eyebrow and eyelid lacerations (n=160, 43%), lacerations around the eye (n=98, 27%), and orbital fractures (n=62, 17%). Most eye injuries were right sided (n=197, 53.3%) and the majority of fighters with eye injuries lost their match (n=228, 62.8%). Fifty-seven fighters were recommended for further ophthalmology clearance after the match. The most common reasons for recommended ophthalmology follow-up was orbital fracture (n=25, 44%) and retinal injury (n=7, 12%). Forty-three fighters received no-contact requirements relating to their injury for an average of 8.9 weeks (range 1–24 weeks).

Conclusion

Ophthalmic injuries in professional MMA were prevalent, were most often lacerations surrounding the eye, and often accompanied the fighter losing their match.

Prevalence of Dentofacial Injuries and Concussions Among College Athletes and Their Perceptions of Mouthguards

PURPOSE

The purpose of this study was to determine the rates of dento-facial injuries and concussions among National Collegiate Athletic Association (NCAA) division 1 college athletes and their perceptions of mouth-guards and their protection role in injury prevention.

MATERIALS AND METHODS

A specific survey regarding the experiences of dento-facial injuries and concussions, attitudes towards the mouthguards, and knowledge of dental first aid was distributed to 682 NCAA division I college athletes registered at Columbia University. The independent predictor variable was sport type (contact versus noncontact). The dependent outcome variables were dental injury rate, facial injury rate, concussion rate, mouthguard use, knowledge of dental first aid. Chi-squared and independent sample tests were used for statistical analysis.

RESULTS

The mean age of the athletes was 19.4 years (range: 17 to 22). 107 (47.6%) athletes were male. Only 62 (27.6%) athletes reported mouthguard use during gameplay. The most popular choice of mouthguard was the mouth-molded type (56.7%). Mouthguard use was significantly more prevalent among contact sport athletes (43.3% versus 1.2%; P < 0.01). Contact sport athletes were more likely to experience dental injuries (14.3% versus 0.0%; P < 0.01)., facial injuries (35.0% versus 6.2%; p < 0.01), and concussions (32.6% versus 2.4%; P < 0.01) relative to noncontact sport athletes. No significant difference was identified between contact and noncontact sport athletes with regards to knowledge of dental first aid.

CONCLUSIONS

Contact sport athletes are significantly more inclined to suffer dento-facial injuries and concussions relative to noncontact sport athletes. Thus, mouthguard use and knowledge of dental first aid should be particularly reinforced amongst contact sport athletes.

Mouthguards in dentistry: Current recommendations for dentists

Properly fitted mouthguards reduce the risk and severity of orofacial injury, to both hard and soft tissues, preventing thousands of dollars of trauma management. In this review, findings from recent research will be evaluated to discuss the strengths and limitations of the different types of mouthguards, including their indications by sport. Design, ideal dimensions, and other characteristics will also be explored. Additionally, patient education and motivation will be examined, with a focus on the dentist's role in this regard. Finally, in addition to proper oral hygiene, the importance of proper mouthguard maintenance and evaluation will be discussed. This review will therefore be able to act as a guide for dentists looking to provide patients of all ages with personal protective equipment and stay up-to-date on recent developments in this branch of the sports dentistry field.

Prevalence of orofacial injuries in wheeled non-motor sports athletes: A systematic review and meta-analysis

BACKGROUND/AIMS

As the popularity of sports activities grows, so do the number of sport-related injuries. Furthermore, sports that use equipment or vehicles that modify the speed of the player can present more serious injuries. The aim of this systematic review was to identify the overall prevalence of orofacial trauma in wheeled non-motor sports athletes.

METHODS

The search strategy was applied in eight electronic databases (Embase, LILACS, Livivo, PEDro, PubMed, Scopus, SportDiscus, and Web of Science). Additionally, a complementary search of the gray literature (Google Scholar, OpenGrey, and ProQuest Dissertations & Theses Global), reference lists of included articles, and studies indicated by experts on the subject was done. The included articles were observational studies with sufficient data of orofacial trauma (type and anatomical site) in wheeled non-motor sport athletes, regardless of the competition level. Risk of bias was assessed by using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The meta-analysis was performed using R Statistics software, and the strength of cumulative evidence was assessed by The Grading of Recommendations Assessment, Development, and Evaluation.

RESULTS

From 4042 identified studies, after the removal of duplicates and phase one of selection (title and abstracts screening), 251 studies remained for phase two (full-text screening). Five articles were finally included. One study was considered to have a low risk of bias and four had a moderate risk of bias. The cumulative prevalence of orofacial injuries in wheeled non-motor sport athletes was 21.7% (CI: 8.7-34.7; I² :97.6%) and the prevalence of dental injuries in these sports was 7.5% (CI:4.3-10.7; I² :61.9%). The certainty in cumulative evidence was considered to be very low.

CONCLUSION

About 22% of the wheeled non-motor sport athletes have suffered orofacial injuries. The most prevalent type of injury was classified as dental trauma.

Sport and Dental Traumatology: Surgical Solutions and Prevention

Trauma is a worldwide cause of millions of deaths and severe injuries every year, all over the world. Despite the limited extension of the oral region compared to the whole body, dental and oral injuries account for a fairly high percentage of all body traumas. Among head and neck traumas, dental and facial injuries are highly correlated to sport activities, and their management can be a real challenge for practitioners of any specialty. In case of trauma directed to periodontal structures, restorative and endodontic solutions may not be sufficient to achieve a definitive and long-lasting treatment. This article aims to illustrate surgical options and appliances to prevent dental injuries that may be available to the clinicians treating dental trauma involving oral soft and hard tissues.

Thickness change and deformation of custom-made mouthguards after two years of use by Bangladeshi field hockey players

BACKGROUND/AIM

Sports mouthguards are effective devices that prevent dental trauma in sports activities. Players should change mouthguards on a regular basis because of thickness reduction and shape deformation. However, there is no guidance regarding the best timing to change mouthguards. The aims of this study were to analyze the thickness change and deformation of mouthguards after 2 years of use in Bangladesh field hockey players and to consider appropriate evaluation criteria.

MATERIAL AND METHODS

Fifty-seven field hockey players belonging to the Bangladesh Sports Education Institute participated in this study. Participants were provided with double-layered mouthguards made of polyolefin-based material using a vacuum-forming machine. Mouthguards were fabricated using 2-mm-thick sheet as the first layer and 3-mm-thick sheet as the second layer. Players used the mouthguards for 2 years. Before and after using the mouthguards, the thicknesses of nine areas were measured. In addition, the lengths of five areas were used to analyze shape deformation.

RESULTS

After 2 years, the thicknesses of all measured areas had significantly reduced, and the lengths had significantly increased. Thickness reduction of the posterior-occlusal and anterior-incisal areas and deformation of the posterior-buccal and posterior-palatal areas were significantly larger than those in other measured areas.

CONCLUSIONS

Mouthguards should be changed on a regular basis to minimize thickness reduction and deformation. Occlusal and incisal thickness and length of the buccal-posterior area and the palatal-posterior area are factors to be considered in establishing guidelines regarding the timing of mouthguard change.

Analysis of microorganisms in periapical lesions: A systematic review and meta-analysis

AIMS

The aim of this study was to systematically review the literature on prevalence of microorganisms and their viability/activity in endodontic periapical lesions.

DESIGN

Literature research was performed on five electronic biomedical databases from their start dates to June 2020. Only studies evaluating the presence of microorganisms in periapical lesions in human permanent teeth with secondary/persistent infection were included. Two reviewers independently assessed the eligibility for inclusion, extracted data and evaluated the risk of bias. Meta-analysis and binominal tests were used to analyse the resulting data.

RESULTS

From the 1,313 records found, 23 full-texts were included for qualitative and quantitative analysis. The prevalence of microorganisms in endodontic periapical lesions was 87 % (95 % CI, 75-94) and the prevalence of viable/active microorganisms was 82 % (95 % CI, 66-91). There were statistical differences in the geographic area subgroup and between viable bacteria and active viruses. The most common detection method of microorganisms was the molecular one (69 %), and the most prevalent bacteria were the species Actinomyces, Fusobacterium and Prevotella (40 %). Most of the included studies had moderate risk of bias.

CONCLUSIONS

The prevalence of microorganisms in endodontic periapical lesions was 87 % and the prevalence of viable/active microorganisms was 82 %.

Is There Association Between Stress and Bruxism? A Systematic Review and Meta-Analysis

This systematic review and meta-analysis aimed to investigate a possible association between stress and bruxism in humans. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines under the code CRD42020188862, and the searches were performed on the following databases: PubMed, Scopus, Web of Science, Cochrane, LILACS, OpenGrey, and Google Scholar. This systematic review evaluated observational studies in adult humans with and without stress to verify the association between bruxism and the presence of stress. The risk of bias was evaluated through the Joanna Briggs Institute Critical Appraisal Tools for Analytical Cross-Sectional Studies. In quantitative analysis, the Odds Ratio (OR) and their 95% confidence interval (CI) were calculated through a fixed-effect model. Furthermore, a summary of the overall strength of evidence was presented using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). A total of 1,458 studies were identified, and six were included in this systematic review. Two studies included were classified with a low risk of bias, and the others were classified with a moderate risk of bias. In three articles, a meta-analysis was performed and showed an association between these two factors (OR 2.07 [1.51, 2.83], p < 0.00001, I ² = 45%). Besides that, a low certainty of the evidence was detected among this association. Stressed individuals show a higher chance of presenting bruxism when compared to healthy individuals. Despite the low heterogeneity found in the quantitative analysis among the articles reporting an association between stress and bruxism, further studies with similar methods are necessary to understand this relationship better.

ASSOCIATION BETWEEN LEVELS OF SPORTS PARTICIPATION AND ORAL INJURIES AMONG COMBAT ATHLETES

ABSTRACT 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.

Health-Risk Behavior-, Mental Health-, and Physical Exercise-Related Risk Factors for Tooth Fractures in Korean Adolescents

We aimed to determine factors related to tooth fracture experience in Korean adolescents. This study used data from the 14th Korea Youth Risk Behavior Survey in 2018, a cross-sectional web-based survey of health-risk behaviors among a representative sample of Korean middle- and high-school students aged 12–17 years. A total of 60,040 participants were selected using a complex sampling design of the survey from 400 middle schools and 400 high schools. They answered a self-administered questionnaire survey in classrooms. Explanatory variables included those pertaining to health-risk behaviors, mental health, and physical exercise. Complex-sample multivariable logistic regression models were applied to identify factors related to tooth fracture experience in the past 12 months. The overall prevalence of dental fracture experience was 11.4%. Risk factors related to tooth fractures in Korean adolescents were unhealthy behaviors such as alcohol and tobacco consumption; mental health problems including stress, depression, and suicidal ideation; and intensive physical exercise. The major risk factor related to tooth fractures was depression. To prevent tooth fractures among adolescents, schools should strengthen mental health education, encourage mouthguard use during intensive physical exercise, and develop school environments to prevent orofacial injuries. Further studies on various risk factors related to tooth fractures are warranted.

Comprehensive analyses of maxillofacial fractures due to non-professional sports activities in Italy

BACKGROUND/AIM

Sports activities have become increasingly popular among amateurs and this has led to an increase in maxillofacial fractures. The aim of this study was to investigate the management of amateur sport-related maxillofacial fractures and appropriate preventive measures.

METHODS

A trauma database was used to analyze 3231 patients with maxillofacial fractures admitted to the Maxillofacial Surgery Division of Città della Salute e della Scienza Hospital, Turin, Italy, from January 2001 to December 2019. Only patients with non-professional sports-related maxillofacial fractures were included. The following data were collected: age, gender, type of sport, mechanisms of injury, sites of fracture, Facial Injury Severity Scale, associated injuries, month of trauma, time to treatment, treatment, length of stay, and interval before return to sport.

RESULTS

There were 432 patients, 378 males and 54 females, with a mean age of 29.2 (5-76 years). Sport-related maxillofacial fractures' relative percent ranged from 11.1% in 2001 to 17.5% in 2019. Soccer was the most common cause of sport-related maxillofacial fractures (54.2%), and impact with a player/opponent was the main mechanism of injury (72%). An intentional violent act (player hit by a fist) was the cause of fracture in 8.5% of the soccer-related injuries. Fractures of the middle third of the face occurred in 61.2% of patients. Maxillofacial fractures were treated within 24 h in 25% of patients. There were 343 out of 412 patients who received open reduction and internal fixation (mean length of hospital stay: 3.7 days). There was no contraindication to resuming sport activities at 30/40 days after treatment, except for combat sports.

CONCLUSIONS

This study provided further evidence of a relative increase in sports-related maxillofacial fractures. Soccer is related to the majority of sport maxillofacial fractures. Adherence to the rules is necessary to limit violent acts that cause such injuries. In non-professional players, resumption of the full activity is allowed after 40 days for non-combat sports.

Determinants for traumatic orofacial injuries in sport: Extrinsic factors in a scoping review

BACKGROUND/AIM

Sports practices carry a risk for orofacial injuries and, to avoid them, preventive measures are necessary. The aim of this study was to investigate a web of extrinsic determinants for orofacial trauma in sports.

MATERIALS AND METHODS

Through a scoping review, eight extrinsic risk factors for sports-related orofacial trauma emerged from the thematic analysis. These were sports modality, sports philosophy, competition rules, level of competition, accessory equipment, environmental conditions, acting regimen, pitch conditions, and human resources. The data collection was conducted on seven databases, using terms based on health science descriptors and keywords related to orofacial trauma and sports.

RESULTS

From the 1155 articles found, 157 were selected based on eligibility criteria and classified according to the mentioned factors. After the full reading of the articles, the most cited risk factor was sports modality while acting regimen and environmental factors were the least mentioned. Therefore, a scheme following the web of determinants was constructed with the purpose of establishing a risk profile, which was based on the interactions between the determinants and on the frequency that they were mentioned as contributors to injury. From this, it was observed that each traumatic event is possibly a result of the interrelationships among the eight suggested determinants.

CONCLUSION

Sports modality was the most cited extrinsic determinant observed in the literature, while environmental conditions and acting regimen were the least cited. In addition, more than establishing the determinants, it is necessary to comprehend how they relate, once preventive strategies should intercede on these relations, to help reduce sports injuries.

Improving the Wearing Rate of Mouthguards in the Youth Rugby Category Affects the Total Future Mouthguard Wearing Rate

The aim of this study is to consider the hypothesis that wearing mouthguards (MGs) from a young age helps to shape players’ habit of continuing to wear MGs as adults. In addition, we consider the mandatory rule of wearing mouthguards in the youth category on the future wearing rates of mouthguards. Eighty-five Japanese male amateur rugby players were included in this study. We examined the relationship between the wearing rates of mouthguards when participants were high school students and as adults (in 2018) using a questionnaire. Collected data were classified into categories (age, mouthguard type, and applied mandatory rule or not), and their relationships were analyzed. The wearing rate of mouthguards in high school was significantly related to the wearing rate of mouthguards in adulthood (χ2 = 12.1, p < 0.01). The mandatory rule to wear mouthguards at high school was related to the wearing rates of mouthguards as adults, but not significantly (χ2 = 3.42, p = 0.06). Participants’ mouthguard wearing rates as adults were affected by their high school wearing rates. The mandatory rule of wearing mouthguards in the youth category may be somewhat effective for improving mouthguard wearing rates; however, it is more important to provide knowledge about their importance.

Knowledge regarding avulsion, reimplantation and mouthguards in high school children: Organised sports-related orodental injuries

Purpose:

To assess knowledge, awareness and attitude of high school children involved in various sports activities regarding avulsion, reimplantation and mouthguard use.

Materials and Methods:

An interview-based study was conducted among high school children in the age group of 8–16 years (n = 1105). A questionnaire was given to children and parents which included questions based on knowledge of children regarding avulsion, reimplantation, consequences of losing teeth, mouthgards and their usage and preferred media for tooth transportation. The research proposal was submitted to the ethics committee and the study design was approved. Data analysis included descriptive statistics and Statistical Package for the Social Sciences (SPSS) software.

Results:

Only 37.6% of the children knew that their teeth can be completely knocked out with injury and 20.1% knew that a knocked-out tooth can be replanted. The preferred media for tooth transportation were gauze/cotton (27.2%), handkerchief (17.5%), paper (14%), water (13.8%) and cellophane (1.3%), i.e. 81.3% of the children preferred dry transport media. Among the children playing contact sport, 53.8% did not know about mouthguards and the rest 46.2% knew about it, but most of them never used it.

Conclusion:

Considering the lack of awareness among children, as well as the people around them, there appears to be a crucial need for education of public and to determine dental manpower and dentists to increase awareness.
