This regional 2-center study was designed 1) to analyze the clinical features of all patients with odontogenic orofacial infection as per type of visit, 2) to analyze the clinical features of diabetic patients compared with nondiabetic patients, and 3) to identify potential variables that may associate with long length of stay (LOS) of patients admitted for orofacial odontogenic infection in Northern Peninsular Malaysia. All adult patients with orofacial odontogenic infections who attended the Oral and Maxillofacial Department of Hospital Raja Permaisuri Bainun and Hospital Sultan Abdul Halim from March 2015 to February 2019 were included. Data on patients' demography, medical history, smoking status, clinical presentation, and LOS were collected. Multivariate logistic regression analysis was performed using the dichotomous dependent variable, namely, short LOS (LOS <5days) and long LOS (LOS ≥5days). A total of 355 patients were reported with the mean age of 39.93±15.95years old. Multivariate analysis revealed that diabetes (adjusted odds ratio=4.387, 95% confidence interval=1.453 to 13.241, Pvalue=.009) and multiple space involvement (adjusted odds ratio=4.859, 95% confidence interval=1.280, 18.454, P value=.020) were responsible for long LOS. Judicious treatment is recommended when treating patients of such infection that involves multiple spaces with underlying diabetes mellitus.
