This study aimed to statistically analyze the types of oral and maxillofacial problems and corresponding treatments provided from October 2018 to September 2022, and to describe the trends of dental service pre and post COVID-19 outbreak.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The medical records of all patients visited to the CHN L2 during the 48 months were collected and were accessed for the research purposes between October 2018 and September 2022. Dental visitors were counted and identified with nationality and occupations. Dental service was categorized as emergency, routine and evacuation.

The proportion of UN military personnel is 91.39% (870\/952). A total of 1,116 teeth and mucosa problems were treated. Dental emergencies represented 13.98% percent (156\/1, 116). 2,180 dental treatments (2.29 procedures per patient) were provided: dental radiographs taken (618, 28.30%), local anesthesia (448, 20.55%), RCT (373, 15.14%), resin composite filling (330, 15.14%), extraction (248, 11.38%) and other treatments (164, 7.52%). The number of monthly visitors was significantly affected by the COVID-19 epidemic (<jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05), pre-COVID-19 (total 151\u2009\u00b1\u200951, dental 33\u2009\u00b1\u200913) and post-COVID-19 (total 51\u2009\u00b1\u200921, dental 13\u2009\u00b1\u20098), the lowest number was in July 2020, 6 months after the COVID-19 outbreak (total 16 and dental 3).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Dentistry is the most frequently visited department in the CHH L2 in Bukavu, and the number of visitors were affected by the COVID-19 epidemic. Treatments related to dental caries, pulpitis, apical periodontitis, and wisdom teeth problems account for the majority of dental service. The variety and severity of dental problems demonstrate the urgent need for training in multiple specialized skills for deployed military dental personnel.<\/jats:p><\/jats:sec>","DOI":"10.3389\/froh.2025.1527777","type":"journal-article","created":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T06:38:44Z","timestamp":1740033524000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Dental
