Periodontitis is a group within the periodontal disease where the support tissue is affected as a result of an imbalance between aggressive and bacterial host immune response. Radiographic examination is a noninvasive method that when used properly can provide images that show early bone loss. Assessment of bone density has been previously described. This study aimed to assess changes in bone density of the alveolar crest in the period of four months, both in patients with chronic periodontitis before and after primary therapy, and in periodontally healthy patients. Patients in both groups underwent periodontal examination with Florida Probe ®, to assess the presence of periodontitis and also the change of clinical parameters after primary therapy. Six radiographs were taken per patient at each time of evaluation. From these images we performed the evaluation of alveolar crest bone density over areas of interest (ROI) using the Kodak Dental Imaging Software 6.7 ®. Comparisons between radiographic measurements taken at baseline and follow up, did not show differences for ROI 1, ROI 2, JCE-CO in both groups. Thus, we observed that the group of patients with chronic periodontitis showed no significant difference in bone density of the alveolar crest 4 months after treatment, even with improvement of clinical periodontal parameters. The group of periodontally healthy patients did not show density changes at the same time.
