Abstract

Background: According to the 2014 National Oral Health Study, 5.20 % of the Colombian population has total edentulism and 32.8 % in the population over 65 years of age. However, other parameters relevant to the correct approach to edentulism should be analyzed with radiographic studies. Purpose: To identify the frequency and characteristics of the findings and bone variations in panoramic radiographs of totally edentulous patients. Methods: A descriptive, observational study was carried out on 10.000 panoramic radiographs, from which those corresponding to patients with total edentulism were analyzed using the CliniView 9.3 program. Variables of sex, age, alveolar ridge height, mandibular branch height and condyle, as well as radiographic findings were recorded. Results: 112 radiographs of patients with total edentulism were found, 51.8 % with some type of incidental finding. Most frequent were implants 33.9 % followed by root remains in 13.4 %. There were no differences in the averages of the bone measurements on both sides. Men have higher alveolar ridge height in the lower jaw than women (p <0.05). Condylar height values ​​were similar for both sexes. A higher value of the height of the mandibular branch was found in men (p <0.05). Conclusions: Frequency of radiographic incidental findings in total edentulous patients is considerable. The bony variations caused by the absence of teeth must be taken into account when making clinical decisions of restoration with total prosthesis or with implants.
