Dentofacial inflammation resulting from untreated dental caries is a serious disease that can spread to deeper tissues of the neck and face. This study aimed to analyze salivary cytokine profiles as potential biomarkers of acute odontogenic infections in children. The study group consisted of 28 children aged 3-17 years old with acute dentofacial infections (DI) and a control group (caries experience, CE) of 52 children aged 4-17 years old with uncomplicated dental caries. The cytokine profile was analyzed using the Bio-Plex Pro Human Cytokine 27-Plex kit in the saliva of children in both groups. The levels of IL-4, IL-15, FGF-2, G-CSF, and PDGF-BB were significantly increased in children with dentofacial infections compared to the control group. In contrast, the levels of other cytokines, such as IL-2, IL-7, IL-9, IL-13, GM-CSF, and IFN-γ, did not show statistically significant differences between these two groups. IL-4, IL-15, FGF-2, G-CSF, and PDGF-BB may serve as potential selective biomarkers of inflammation of the oral cavity in children. These biomarkers can be useful in identifying and monitoring the progress and treatment of bacterial infections resulting in dentofacial inflammation.

Saliva contains various proteins that are important in developing inflammatory processes and their prevention. One key aspect of saliva research is the relationship between oral infections and inflammation, and the role of some salivary proteins.

To demonstrate which salivary cytokines can be biomarkers of acute odontogenic oral and facial infections in children.

The study included two groups of patients: a study group of 28 children: 7 girls and 21 boys aged 3 -17 years with acute dentofacial inflammation (DI) and a control group of 52 children: 16 girls and 36 boys aged 4-17 years with uncomplicated dental caries (CE). The levels of Interleukin-5 (IL-5), Interleukin -10 (IL-10), Interleukin-17A (IL-17A), Interleukin-12p70 (IL-12p70), Eotaxin, Rantes, Vascular Endothelial Growth Factor (VEGF), and Interferon gamma-induced protein 10 (IP10) in the saliva of children in DI and CE groups were compared. Statistical analysis was performed with Statistica 13. The Student's t-test and the Wilcoxon signed-rank test were used.

The results show that IL-10, IL-17A, and Eotaxin showed a statistically significant increase in the DI group compared to the CE group. The significance level for IL-10 was p=0.02, for IL-17A was equal to Eotaxin and p=0.04. The other measured parameters did not differ statistically significant between the two groups.

IL-10, IL-17A, and Eotaxin can be used as potential biomarkers for tooth-related inflammatory states of the oral cavity and face in children. These biomarkers can be useful in identifying and monitoring the presence of inflammation in the oral cavity and face.

Tongue abscess (TA) is a very rare clinical condition and its treatment is very important. Surgical drainage is at the forefront in the treatment. Our study includes patients with tongue and tongue base abscesses.

To discuss the clinical and laboratory findings of these patients emphasizing the underlying causes and treatment options with the largest patient series in the English literature.

We included patients with isolated TA who applied to our clinic between January 1, 2020 and January 1, 2023. Those who lack the recorded data, those who are not between the ages of 18-66, those who have not undergone surgery-interventional procedure, and those who have infection and/or abscess in another place were excluded from the study.

There were two female (18%) and nine male (82%) patients in our series consisting of 11 patients. Their ages ranged from 18 to 66, and the mean ± SD was 48.63 ± 16.3. Considering the localization of the abscess, three anterior abscesses (27%), two lateral abscesses (18%), and six abscesses at the base of the tongue (54%) were detected.

Tongue abscesses can cause acute upper airway obstruction and respiratory collapse. It may be necessary to act quickly for the tracheotomy procedure and this procedure can usually be performed under local anesthesia as intubation cannot be achieved. When we encounter an abscess in an unexpected organ, difficulties may be encountered in the management of the patient.

The most common cause of the development of odontogenic infection is untreated dental caries, which initially leads to pulpitis. If an odontogenic infection is left untreated, it will pass through the limiting bone plate and will infiltrate deeper structures. Odontogenic infections are different in adults and children. The study was conducted at the Department of Pediatric Otolaryngology and Pediatric Head and Neck Surgery of Upper Silesian Children's Health Center in Katowice in the 2020-2022. We included 27 patients aged 2-16 in the study. Patients were diagnosed with an active, acute odontogenic inflammatory process in the head and neck area. We assessed pain, trismus, extraoral and intraoral swelling and the level of CRP [C Reactive Protein], WBC [White Blood Cells], NLR [Neutrophil Lymphocyte Ratio], D-dimers and Prealbumins. The results were analyzed in terms of the location of the source of inflammation: maxilla or mandible and the type of source of infection: deciduous tooth or permanent tooth. Deciduous teeth are more often the cause of odontogenic infection in the maxilla, while permanent teeth in the mandible. Trismus, extraoral, and intraoral swelling occurred in all infections caused by permanent teeth. The CRP and NLR ratio is statistically higher in infection, which originates from permanent teeth. The mean hospitalization time was also longer for infections from permanent teeth 3.42 days than for deciduous teeth 2.2 days. The varied clinical picture of odontogenic infections in children requires periodic analyzes of statistical data related to epidemiology, etiology, and symptomatology in order to update diagnostic and therapeutic procedures.
