Author Correction: Gene-environment correlations and genetic confounding underlying the association between media use and mental health.

Odontogenic infections originate in the teeth or periodontium []. If the inflammatory reaction progresses from apical periodontitis, subperiosteal bone areas are initially affected, followed by various soft tissue regions []. As the infection spreads, life-threatening complications such as necrotising fasciitis, mediastinitis or sepsis are not uncommonly seen [, ]. Due to the incidence of these infections, in addition to the dangers to the individual, high economic costs are often incurred, mainly due to surgical interventions, the length of hospital stay (LOS) or intensive care treatments [–]. Predicting treatment outcomes and managing therapy is challenging for treating physicians, especially in cases of extensive infections [, ]. Due to a lack of improvement or worsening symptoms, it is not uncommon that revision surgeries or transfers to the intensive care unit are necessary, which significantly prolongs the LOS []. To support decision-making in everyday clinical practice, prognostic markers such as procalcitonin (PCT) have become established in various specialist areas and are routinely used for risk stratification in patients with severe respiratory tract infections [] or sepsis []. Despite the potentially life-threatening nature of odontogenic infections, evidence on the clinical value of PCT for their assessment remains scarce [–].
