    Abstract:
    The objective of the study was to compare the ability of dental, ENT and radiology specialists to identify the dental cause of maxillary sinusitis with conventional computed tomography, dental and panoramic radiographs. Out of 34 dental records from subjects treated at ENT and Oral and Maxillofacial Surgery Department, LUHS Kaunas Clinics, 22 females and 12 males with the diagnosis of odontogenic maxillary sinusitis, periapical (DPA), panoramic (DPR) and computed tomography (CT) images of posterior maxilla were selected for further studies. In total, 39 sinuses with an odontogenic and 37 sinuses with only rhinogenic cause (control group) were included in the study. Sinuses with mucosal thickening less than 3 mm were excluded from the research. Each image was evaluated by 5 endodontologists, 5 oral surgeons, 6 general dentists, 6 otorhinolaryngologists and an experienced oral radiologist. DPR and DPA views were not evaluated by ENT specialists. The dental cause of maxillary sinusitis was marked according to the given scale. Intraclass correlation coefficient and ROC curve statistical analysis were performed. The best accuracy was observed when CT views were evaluated by experienced oral radiologist and oral surgeons: the AUC was 0.958 and 0.859, respectively. DPR views showed the best accuracy when evaluated by oral surgeons (0.763) and DPA-by endodontologists (0.736). The highest inter-rater agreement was observed between experienced oral radiologist and oral surgeons/otorhinolaryngologists (0.87/0.78) evaluating CT. Sensitivity and specificity of CT were 89.7 and 94.6%, DPR-68.2 and 77.3%, DPA-77.9 and 67%. Identification of dental cause of maxillary sinusitis sometimes is a challenge, which depends on radiological method and, more importantly, on evaluator's experience.
