Objective:To analyze the oral health condition of the crew of a ship by carrying out oral examination，so as to provide reference for offering better medical services.Methods:A total of 816 crew members of a ship were divided into two groups：new crew group with 186 members（onboard time ≤ 1 year）and old crew group with 630 members（onboard time > 1 year）. Indicators related to dental caries，periodontal disease，and wisdom teeth were recorded and analyzed statistically.Results:Among the 816 crew members，the caries prevalence rate was 42.7%，the per capita caries was 0.98，the periodontal health rate was 22.3%，the calculus detection rate was 75.9%，the materia alba detection rate was 9.27%，and the wisdom teeth detection rate was 49.6%. The new crew had worse rank sum test results than the old crew regarding the number of dental caries，decayed-missing-filled teeth，and the calculus index（CI）（ P<0.05）. While the new crew had better results than the old crew regarding the number of teeth loss due to caries（ P<0.05）. In all，799 teeth needed dental treatment；71 teeth were missing and needed to be repaired；619 patients needed supragingival scaling；and 1，005 impacted wisdom teeth needed to be removed. Conclusion:The oral health of the crew is not optimistic，therefore，more oral medical services are needed. Early prevention of oral diseases and oral health education should be strengthened，early treatment of oral diseases should be carried out routinely，and oral examination and intensive treatment should be conducted regularly.
