Abstract: Objectives:To understand the characteristics of oral disease management at sea by analyzing the diagnosis and treatment needs and countermeasures of oral diseases in officers and sailors on an escort mission in the context of public health emergencies,so as to provide a point of reference for dentists on future escort missions,as well as improve the overall capability of oral healthcare at sea.Methods:Different oral diseases among ship crew members during escort missions,along with corresponding treatment measures,were recorded and statistically analyzed.Results:Oral diseases associated with the highest clinical visit rate during escort missions were positive dental calculi,caries,ulcers,pericoronitis of wisdom teeth,wedge-shaped defects,and residual roots and crowns. The most common dental treatment procedures performed at sea were dental filling and ultrasonic scaling. The main emergency diseases were pericoronitis of wisdom teeth,acute pulpitis,and acute periapical periodontitis.Conclusion:In the context of public health emergencies,there is a high demand for oral healthcare among officers and sailors on escort missions,with a primary focus on caries,periodontal diseases,and pericoronitis of wisdom teeth. Therefore,it is necessary to strengthen the oral healthcare during operational and non-operational periods.
