Oral health problems in high-performance athletes at 2019 Pan American Games in Lima: a descriptive study

Periodontal disease and sports performance: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to assess the association between athletic performance and periodontal disease (PD). Observational studies published up to April 2022 were searched in online databases (PubMed, Scopus, Web of Science, The Cochrane Library, LILACS, OpenGrey, and Google Scholar). PECO statement focused on studies with professional athletes (Participants) with PD (Exposition) compared to those with healthy periodontium (Comparison) and its effects on sports performance (outcome). Searches were conducted according to the PRISMA guidelines (registration protocol: 10.17605/OSF.IO/7ADH6) and risk of bias evaluation according to the Joanna Briggs Institute checklist. A total of 793 references were retrieved, of which eight were considered eligible. Two studies did not show an association between clinical PD parameters and performance. A meta-analysis with 396 participants suggested a relationship between PD and self-reported reduction in sports performance (odds ratio [OR] = 1.55; 95% confidence interval [CI] 1.04-2.31; p = 0.03; I2 = 0%) with moderate quality of evidence accordingly GRADE analysis. Despite the differences in performance evaluations between studies, PD was associated with reduced self-reported sports performance. Additional studies assessing confounding factors and objective assessment of PD and performance are needed to clarify the real effect of both conditions.

Twenty-first century knowledge mapping on oral diseases and physical activity/exercise, trends, gaps, and future perspectives: a bibliometric review

Maintenance and improvement of an individual's overall well-being require a multidisciplinary approach that encompasses everything from oral health care to regular physical exercise. The notion that poor oral health can influence general health and athletic performance has sparked an interest in this relationship. This study offers an overview of relevant research and a knowledge map,and discusses publication metrics and key topics concerning the relationship between physical activity or exercise and oral diseases. We searched the Web of Science database for articles published in the 21st century that addressed the relationship between physical activity and oral diseases. Under the stipulated inclusion criteria, a rigorous selection process yielded 276 from 3,883 retrieved articles. The articles were classified by what was assessed as follows: occurrence of oral diseases in athletes or sports enthusiasts (n = 174); impact of physical activity or exercise on the oral cavity (n = 59); effects of oral changes on sports performance and physical fitness (n = 31); and the connection between oral health status, physical activity or exercise, and systemic conditions (n = 12). Orofacial trauma has received the most attention among all investigated oral diseases. However, there is a need for greater attention of dysfunctional habits that can contribute to premature tooth wear, as well as oral inflammatory diseases that can have systemic implications. This mapping can encourage the development of new primary research.

How do infectious diseases affect high-performance athletes? Norovirus during the Lima 2019 Pan American Games

Background and Aims

The incidence of infectious diseases among athletes during international competitions is a concern for public health. In this study, we aim to report six cases of norovirus-associated gastroenteritis among athletes in Lima 2019 Pan American Games, a multisport event held in Peru.

Results

During the Lima 2019 event, there were no reported outbreaks or cases of most frequent diseases, however, six cases (0.09%) of norovirus-associated gastroenteritis were reported. The clinical stage of the cases was self-limited to 2 days, and the main treatment was fluid replacement. Of the six affected athletes, five came from the United States and one from Chile. Only one karate athlete from the United States, could not continue with the competition due to the illness.

Conclusions

The incidence of norovirus-associated gastroenteritis among athletes in Lima 2019 was low, and the clinical course of the illness was self-limited. We conducted a retrospective analysis of medical records of athletes who presented with gastroenteritis using the Panam Sport In previous sporting events, such as the 2017 World Athletics Championships in London, Injury and Illness Surveillance System. These findings can inform the development of public health strategies for the prevention and control of infectious diseases among athletes during international competitions.

Sports Diet and Oral Health in Athletes: A Comprehensive Review

Food and fluid supply is fundamental for optimal athletic performance but can also be a risk factor for caries, dental erosion, and periodontal diseases, which in turn can impair athletic performance. Many studies have reported a high prevalence of oral diseases in elite athletes, notably dental caries 20-84%, dental erosion 42-59%, gingivitis 58-77%, and periodontal disease 15-41%, caused by frequent consumption of sugars/carbohydrates, polyunsaturated fats, or deficient protein intake. There are three possible major reasons for poor oral health in athletes which are addressed in this review: oxidative stress, sports diet, and oral hygiene. This update particularly summarizes potential sports nutritional effects on athletes' dental health. Overall, sports diet appropriately applied to deliver benefits for performance associated with oral hygiene requirements is necessary to ensure athletes' health. The overall aim is to help athletes, dentists, and nutritionists understand the tangled connections between sports diet, oral health, and oral healthcare to develop mitigation strategies to reduce the risk of dental diseases due to nutrition.

Erosive tooth wear and salivary parameters among competitive swimmers and non-swimmers in Egypt: a cross-sectional study

INTRODUCTION

Competitive swimmers spend considerable time practicing their sport. Prolonged exposure to chlorinated water can alter salivary parameters and might compromise oral health. This study aimed to determine erosive tooth wear status and its related risk factors among competitive swimmers as compared to non-swimmers.

MATERIALS AND METHODS

A cross-sectional study consisting of 180 athletes (90 competitive swimmers versus 90 competitive rowers "non-swimmers") was conducted. Participants were interviewed on the common erosion risk factors. The Basic Erosive Wear Examination system was used to assess the status of erosive tooth wear. Stimulated saliva sample was collected before and after a training session and pool pH was evaluated using pH strips for 7 days. Data were analyzed using descriptive statistics and multivariable analysis.

RESULTS

The prevalence of dental erosion was significantly higher among competitive swimmers (60%) with higher BEWE scores compared to non-swimmers (25.6%). The salivary flow rate was reduced significantly after training sessions in both groups while salivary pH increased among swimmers. Evaluation of pool water revealed a continuous reduction in the pH level, reaching a very acidic pH level of 3.24.

CONCLUSION

Erosive tooth wear is more prevalent among competitive swimmers. Years of practice and regular consumption of acidic drinks increase the odds of developing erosive lesions. A high incidence of erosive lesions may be attributed to a reduction in swimming pool pH level. Salivary parameters showed variations between groups after training sessions.

Physical activity as a modifiable risk factor for periodontal disease

Non-communicable diseases (NCDs), which contribute significantly to global morbidity, are largely preventable through behavioral changes. As with other NCDs, periodontitis is associated with modifiable risk factors such as smoking and stress and is linked to multiple adverse health outcomes through a shared pathway of chronic systemic inflammation. While the health benefits of physical activity have been widely promoted in public health and extensively studied for other systemic conditions, its impact on periodontal health has only recently started to gain attention. This article critically evaluates the current literature on the relationship between physical activity and periodontitis. While cross-sectional studies have shown an inverse association between physical activity levels and periodontitis risk in the general population, clinical oral health surveys of elite athletes with high levels of physical activity have nonetheless revealed poor periodontal conditions. Although causality has not been determined, physical activity could positively impact periodontitis directly, by reducing inflammatory biomarkers, and indirectly, through its modulatory effects on insulin sensitivity, obesity, bone density, stress, and other health promoting behaviors. Given the importance of risk factor control during initial periodontal therapy, understanding the role of physical activity as a potential behavioral risk modifier is paramount. The findings of this review provide an evidence-based overview of how physical activity could influence periodontitis. There is a need for longitudinal cohort studies to verify the temporality of the reported associations and exclude confounders, while interventions are needed to assess the efficacy of physical activity on periodontal treatment outcomes.

Knowledge and Self-Assessment of Dental Injuries and Oral Health among Croatian Professional Water Polo Players: A Cross-Sectional Study

OBJECTIVES/AIM

The purpose of this study was to evaluate oral health knowledge, and the incidence of self-reported dental injuries incidence, the frequency of mouthguard use, oral hygiene habits, and oral health status among professional water polo players.

MATERIALS AND METHODS

During the 2022/2023 season, 114 water polo players from the Croatian First League participated in a questionnaire-based online survey. The data collected included sociodemographic and professional attributes, oral health knowledge questions, dental injury experiences, and practices related to mouthguard use. Respondents also rated their own oral health status and oral hygiene habits. The data were analyzed using descriptive statistics and a regression analysis.

RESULTS

The respondents demonstrated inadequate knowledge of oral health, with a mean score of 6.4 ± 2.6 out of 12. Better knowledge correlated positively with older age (p ˂ 0.05) and consistent flossing (p = 0.014). Additionally, 27.2% (31 of 114) of reported dental injuries were related directly to incidents which occurred while participating in water polo. These injuries occurred more frequently during games (54.8%) and often involved the anterior maxillary incisors (71.0%) due to player contact (87.1%). Awareness of mouthguards was high (93.9%), whereas their actual use was low (7.0%) because 35.1% of respondents reported discomfort wearing them. The respondents' self-assessments revealed widespread dental problems, including tooth sensitivity (13.3%), erosion (15.8%), calculus (28.1%), and pigmentation (7.9%).

CONCLUSIONS

The research results indicate a lack of adequate knowledge among the respondents regarding oral health. This deficit was not associated with oral hygiene habits or oral cavity conditions. These findings highlight the disparities in oral health awareness and practices associated with water polo participation and emphasize the importance of education and prevention efforts.

The Impact of Competitive Sports on Oral Health: Exploring Their Relationship with Salivary Oxidative Stress in Children

This article explores the correlation between salivary biomarkers, such as glutathione peroxidase (GPX), total antioxidant capacity (TAC), and superoxide dismutase (SOD), and their association with oral health for children in competitive sports. Saliva has emerged as a valuable resource for evaluating physiological and pathological conditions due to its non-invasive collection method and easy storage. This study examines the potential of GPX, TAC, and SOD as salivary biomarkers for assessing the impact of competitive sports on children's oral health. It discusses the potential implications of increased oxidative stress due to intense physical activity and the role of antioxidant defense mechanisms in maintaining oral health. In total, 173 children aged between 6 and 17 were divided into three groups, 58 hockey players, 55 football players, and 60 in the control group, and examined to assess their oral hygiene and dental and periodontal health. Saliva was collected, centrifuged, and the supernatant was analyzed for the relevant biomarkers. The findings seem to suggest that salivary biomarkers, like GPX, TAC, and SOD, might serve as indicators of the physiological response to competitive sports in children, as well as indicators of oral health, especially dental cavities, and periodontal disease. Statistical analysis showed significant differences between the groups, with better values for athletes, regardless of age, sex, or activity type. Understanding the relationship between salivary biomarkers and competitive sports in children can have significant implications for monitoring and optimizing the health and performance of young athletes. Further research is needed to establish the specific associations between these biomarkers and the effects of several types and intensities of sports activities on oral health in children.
