Epidemiological characteristics and risk factors for prolonged hospitalisation in oral and maxillofacial space infections: a 3-year retrospective study of 217 cases

Periapical periodontitis remains a primary cause of OMSI; however, the rising incidence of infections due to cosmetic injections and implant surgeries warrants attention. Penicillin, clindamycin, and erythromycin are not recommended as empirical first-choice drugs. The predictive model effectively identified risk factors for extended hospitalisation. Hypertension, diabetes, pre-admission interventions, and age are risk factors for lengthened hospitalisation. Efforts should be made to promote oral hygiene education and healthcare system reforms in regions with similar demographic and socioeconomic conditions.
