Determining whether an odontogenic swelling is a cellulitis or fluctuance is difficult but important as both may require different treatments. It has been suggested in the medical and dental literature that the use of an ultrasound may aid in differentiating cellulitis and fluctuance. Therefore, the purpose of this investigation was to compare the accuracy of clinical examination alone versus clinical examination plus ultrasonography in the diagnosis of cellulitis and fluctuant swellings in symptomatic patients with a diagnosis of pulpal necrosis, acute apical abscess or cellulitis, and clinical swelling. Eighty-two emergency patients participated in this study. Each patient was examined and diagnosed by clinical examination and by clinical examination plus ultrasonography. An incision for drainage procedure was performed and a definitive diagnosis was recorded. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. With clinical exam alone, a correct diagnosis was made 56 of 82 times (68.3%). With clinical exam plus ultrasonography, a correct diagnosis was made 57 of 82 times (69.5%). The sensitivity of the clinical exam alone was 30% and for clinical exam plus ultrasonography it was 40%. The specificity was 90.4% for the clinical exam alone and 86.5% for the clinical exam plus ultrasonography. The positive predictive values, negative predictive values, and accuracy values were 64.3% versus 63.2%, 69.1% versus 71.4%, and 68.3% versus 69.5% for clinical exam alone versus clinical exam plus ultrasonography, respectively. In conclusion, the addition of ultrasonography to clinical exam alone did not significantly increase the number of correct diagnoses made.
