Objectives: To evaluate the oral health status of the professional soccer players in Thailand. Methods: Twenty-five
Thailand professional soccer players’ oral conditions were examined and included in this study. DMFT, Quigley
& Hein plaque index (PI), Löe & Silness gingival index, World Health Organization malocclusion index, pocket
depth, TMJ examination and history of dental trauma were recorded. Results: The results demonstrated poor oral
health level including dental caries (84%), DMFT score mean was 10.08, dental attrition (60%) and periodontal
pocket (36%). Thirty percent of all players presented bruxism. More than 40% of athletes were bothered by their
oral health with 28% reporting an impact on quality of life and 18% on training and performance. Conclusion: The
oral health of Thai professional soccer players was poor that may result in negative impact on well-being, training
and performance. As oral health is an important element of overall health and well-being, health promotion is
required to optimize soccer player performance.
