It is believed that the intensity of the immunoinflammatory response in OI is the main prognostic factor. Therefore, in this research, it was pursued to determine if the combination of C-reactive protein (CRP) and Neutrophil to Lymphocyte Ratio (NLR) (CRP-NLR) may serve as potential severity predictors in patients with odontogenic infections. Materials and Methods: A retrospective analysis on 108 patients hospitalized for odontogenic infections was conducted at the Department of Maxillofacial Surgery. Depending on the symptom severity scale, patients hospitalized with OI were divided into two equal groups based on infection severity (SS). Results: Patients with severe OI from Group B were associated more frequently with diabetes mellitus and smoking more often than those with a lower severity from Group A. In Group A, abscesses of odontogenic origin accounted for 70.4% of hospitalizations, while in Group B, abscesses and cellulitis were associated in 55.6% of cases (p-value &lt; 0.001). The disease outcomes were more severe in Group B patients, where 22.2% of them developed sepsis, compared to 7.4% of Group A patients (p-value = 0.030). However, there was no significant difference in mortality rates. The SS and systemic immune inflammation index (SII) scores of Group B patients were substantially higher than Group A patients (13.6 vs. 6.1 for the SS score, p-value &lt; 0.001), respectively, 2312.4 vs. 696.3 for the SII score (p-value &lt; 0.001). All biomarker scores, including the CRP-NLR relationship, were considerably higher in Group B patients, with a median score of 341.4 vs. 79.0 in Group B (p-value &lt; 0.001). The CRP-NLR association determined a 7.28-fold increased risk of severe OI. The receiver operating curve (ROC) analysis of CRP-NLR yielded an area under curve (AUC) value of 0.889, with high sensitivity (79.6%) and high specificity (85.1%), for predicting a severe odontogenic infection using biomarkers measured at hospital admission (p-value &lt; 0.001). Conclusions: Therefore, it can be concluded that CRP-NLR is a reliable and affordable biomarker for determining the severity of odontogenic infections that may be included in other prognostic models for dental infections.<\/jats:p>","DOI":"10.3390\/medicina59010020","type":"journal-article","created":{"date-parts":[[2022,12,22]],"date-time":"2022-12-22T03:24:30Z","timestamp":1671679470000},"page":"20","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["The Role of C-Reactive Protein and Neutrophil to Lymphocyte Ratio in Predicting the Severity of Odontogenic Infections in Adult Patients"],"prefix":"10.3390","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8236-2205","authenticated-orcid":false,"given":"Ovidiu","family":"Rosca","sequence":"first","affiliation":[{"name":"Department XIII, Discipline of Infectious Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bogdan Andrei","family":"Bumbu","sequence":"additional","affiliation":[{"name":"Department of Dental Medicine, Faculty of Medicine and Pharmacy, University of Oradea, University Street 1, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1293-7664","authenticated-orcid":false,"given":"Oana","family":"Ancusa","sequence":"additional","affiliation":[{"name":"Department V, Discipline of Medical Semiology I, Faculty of General Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serban","family":"Talpos","sequence":"additional","affiliation":[{"name":"Discipline of Oral and Maxillo-Facial Surgery, Faculty of Dental Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Horatiu","family":"Urechescu","sequence":"additional","affiliation":[{"name":"Discipline of Oral and Maxillo-Facial Surgery, Faculty of Dental Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9215-5154","authenticated-orcid":false,"given":"Sorin","family":"Ursoniu","sequence":"additional","affiliation":[{"name":"Department of Functional Sciences, Center for Translational Research and Systems Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vlad","family":"Bloanca","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marius","family":"Pricop","sequence":"additional","affiliation":[{"name":"Discipline of Oral and Maxillo-Facial Surgery, Faculty of Dental Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, 300041 Timisoara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1016\/j.anorl.2015.08.007","article-title":"Criteria for admission of odontogenic infections at high risk of deep neck space infection","volume":"132","author":"Alotaibi","year":"2015","journal-title":"Eur.
