Background: This study was conducted to 1. estimate the effect of protein, creatine, and amino acids supplements on the oral health of bodybuilders. 2. compare the oral health status of bodybuilders with another non-bodybuilder group. Methods: This cross-sectional study was conducted in Riyadh city between April and July 2021. About 200 non-smokers Saudi men were recruited in the study which was allocated into two groups (100 subjects each); bodybuilders and non-bodybuilders. Oral health indicators like dental caries, plaque, and gingival indices were measured. Results: D and DMFT were higher in the bodybuilder group than in the non-bodybuilder [4.47 vs 0.89 for D, and 8.75 vs 4.58 for DMFT]. Also, P.I. and G.I. showed the same result. 60 % of participants were taking protein only, while 37% of them were taking a combination of protein, creatine, and amino acids. Only 3% were taking creatine. A positive significant association was found between the frequency of protein intake and D, Pl. I., and G.I. Negative significant association was found between Pl. I score and each of protein and combined intake of protein, creatine, and amino acids. Regarding G.I., combined supplement intake, protein intake, duration, and frequency of brushing were negatively associated with it [p=0.033, 0.026, 0.081, and 0.010 respectively]. Conclusion: From the previous findings we can conclude that poor oral hygiene practices among bodybuilders may be the real cause of their bad oral health. Also, the frequency of protein intake could be directly associated with increased dental caries, plaque accumulation, and gingivitis. While the higher intake of protein and combined supplements were associated with decreased plaque and gingival indices.
