ABSTRACT 

Objectives: This retrospective study aimed to objectively assess bone density values obtained by cone-beam computed  tomography and map the periapical and inter-radicular regions of the mandibular bone.

Material and Methods: In total, periapical bone regions of 6898 roots scanned by cone-beam computed tomography were.  T he results were evaluated retrospectively and recorded using Hounsfield units (HU).

Results: The correlation between periapical HU values of adjacent mandibular teeth was strongly positive (P < 0.01). The  anterior region of the mandible yielded the highest mean HU value (633.55). The mean periapical HU value of the premolar  region (470.58) was higher than that measured for the molar region (374.58). The difference between furcation HU values of  the first and second molars was unnoticeable.

Conclusions: The results of this study tried to evaluate the periapical regions of all mandibular teeth, which could ease bone  radiodensity before implant surgery. Even though the Hounsfield units provide the average radio-bone density, a site-specific  bone tissue evaluation of each case is essential for appropriate cone-beam computed tomography preoperative planning.
