Factors Influencing the Onset of Intra- and Post- Operative Complications Following Tooth Exodontia: Retrospective Survey on 1701 Patients

7Complications after tooth extraction may occur because of several factors correlated to the patient's medical history, surgical site or type of intervention. The aim of this retrospective cohort study was to evaluate type and frequency of complications after exodontic surgery, its correlation with antibiotic administration and between patient's related systemic factors. From June 2015 until February 2016 1701 exodontic interventions, for a total of 2322 extracted teeth, were carried out at the Unit of Oral Surgery in Trieste. Descriptive statistic, and backward multiple logistic regressions were performed to identify the variables associated with the presence of post-operative alveolitis or any other post-operative complication. The presence of coagulopathy and smoking habit were related to high risk of post-operative alveolitis (OR = 5.51, p = 0.035 and OR = 2.5, p = 0.029, respectively). Tooth fracture was found to be correlated with higher probability of post-operative alveolitis (p = 0.001) and concomitant chemotherapy put at a higher risk post-operative complications, including alveolitis (OR = 29.5, p = 0.018). According to the present results, antibiotic consumption did not seem to reduce the incidence of post-operative infective complications (alveolitis). A careful analysis of medical history, the adequate surgical technique, and the correct instructions in post-surgical behavior, prevent the insurgence of intra and post-operative complications.openopenVettori, Erica; Costantinides, Fulvia; Nicolin, Vanessa; Rizzo, Roberto; Perinetti, Giuseppe; Maglione, Michele; Di Lenarda, RobertoVettori, Erica; Costantinides, Fulvia; Nicolin, Vanessa; Rizzo, Roberto; Perinetti, Giuseppe; Maglione, Michele; Di Lenarda, Robert
