Abstract Introduction Differences in bone density before and after endodontic treatment were examined in teeth with periapical lesions in Hounsfield units (HUs) by using cone beam computed tomography (CBCT). Methods Sixteen patients requiring endodontic treatment for periapical lesions underwent CBCT scan before and after treatment. Their bone densities were calculated in HUs. The study included 16 lesions measuring 8–10 mm in diameter. HU measurements were taken from an area of 2.25 mm2 on the CBCT images where the bone density was lowest, before and after treatment. Results The initial and final measurements were compared statistically by using paired samples statistics at the 5% significance level. Conclusions The results of this study support the use of CBCT to measure bone density before and after endodontic treatment.
