Purpose: This study aimed to determine if there is a relation between odontogenic infection severity score (OISS) and difficult intubation at the time of surgical treatment for severe odontogenic infections (SOI). A secondary goal of this study was to determine the utility of OISS as a predictor of difficult intubations.

Methods: This retrospective cohort study was composed of consecutive patients admitted and surgically treated in the operating room (OR) for SOIs. Patients with an OISS ≥ 5 were designated as Group 1 and < 5 Group 2.

Results: There was a statistically significant difference in difficult intubations between the two groups (p = 0.018). Patients with an OISS ≥ 5 were nearly four times more likely to be difficult intubations compared to patients with an OISS < 5 (OR 3.70, 95% CI 1.19-11.45). When OISS ≥ 5 was used to predict difficult intubation, the sensitivity was 69%, the specificity was 63%, the positive predictive value was 23%, and the negative predictive value was 93%.

Conclusion: OISS ≥ 5 was associated with a higher prevalence of difficult intubations compared to an OISS < 5. OISS may provide clinically relevant data that can be used with established risk factors, laboratory values, and clinical judgment.

Background: Odontogenic maxillary sinusitis (OMS) is recognized in literature, but diagnosing it is challenging due to its different and overlapping clinical presentations of it. Misdiagnosis can lead to persistent symptoms and clinical burden. Interestingly, recent guidelines from the American Academy of Otolaryngology-Head and Neck Surgery lack recommendations for dental evaluation in adult sinusitis cases.

Background: Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention.

Odontogenic infections (OIs) can progress rapidly and may lead to severe systemic complications, especially in patients with underlying conditions like diabetes mellitus (DM). This study aims to evaluate the predictive value of inflammatory scores-quick Sequential Organ Failure Assessment (qSOFA), Systemic Immune-Inflammation Index (SII), derived Neutrophil-to-Lymphocyte Ratio (dNLR), and Odontogenic Infection Severity Score (OISS)-in assessing the severity of OIs in diabetic versus non-diabetic patients. A case-control study was conducted on 123 patients diagnosed with OIs.

Background/objectives: Inexperienced dentists and dental students are especially prone to misdiagnosis, and this represents a huge problem regarding antimicrobial stewardship. We aimed to develop a mobile app for rational antibiotic prescribing in dentistry based on local-systemic symptoms and patient factors, rather than solely on diagnosis, to tackle misdiagnosis.

Methods: The study involved 64 participants, 50 of which were third-year dental students attending a pharmacology course focusing on antimicrobials, comprising lectures and practical sessions without (noAPP group, n = 22) or with (APP group n = 28) the assistance of a mobile application.

Introduction: Osteomyelitis is an inflammatory condition of the bone with a multifactorial etiology, including trauma and odontogenic infections. Despite being a common condition in clinical practice, limited research exists on the clinical and pathological profile of Osteomyelitis of the Jaws (OJ). This 51-year retrospective study aimed to describe the clinical, radiographic, and histopathological features of OJ diagnosed at a single oral pathology referral center.
