(PO88) Cemento-Osseous Dysplasia, Its Contemporary Correlations and Mistreatment In The Endodontic Setting

Abstract: Cemento-osseous dysplasia (COD) is often considered in differential diagnoses for teeth with radiolucent lesions surrounding the periapex. The University of Florida’s Dental Clinic has encountered multiple cases that were misdiagnosed, leading to mistreatment. This retrospective study aims to determine the incidence of each type of COD and quantify the number of cases that have undergone endodontic treatment. A secondary aim is to explore possible correlations between patient demographics and COD. Existing imaging modalities for 77 patients diagnosed with COD were evaluated, along with radiographic interpretations and demographic information for each patient. The results demonstrated that the most prevalent type of COD was Florid (55.8%), followed by Periapical (23.4%) and Focal (20.8%). Females (88.3%) were more likely than males (11.7%) to be diagnosed with COD, with 59% of the total number of participants being Black, followed by White (33.8%). Of the total cases, 40.3% had endodontically treated teeth, and only 24.7% of those teeth had a history of sensibility tests being completed. The maxillary arch (59.2%) had a higher prevalence of root canal-treated teeth in patients diagnosed with COD than the mandibular arch (40.8%), and the most common tooth type to be treated belonged to the category of maxillary anterior teeth. In conclusion, COD appears to remain prevalent in African American females. This study revealed that sensibility testing was not routinely done prior to endodontic therapy for patients diagnosed with COD, and the most common teeth to be treated endodontically were maxillary anteriors..
