Presently in our country, the measurement ofalveolar bone in Cone Beam Computed Tomography (CBCT) images is done by oral and maxillofacial radiologists. Most of theclinicians in implant treatment plan,use the measurements provided by radiologist in the CBCT images.The aim of this study is to discover the method approved by most clinicians according to the various methods of linear measurement of alveolar bone. Initial cross-sectional image from different areas of lower jaw was chosen by three radiologists and threeperiodontists. Several measurementswere specified for each of the ridges. The ridges and measurement methods were numbered. 342 dentists comprising 39 radiologists, 85 maxillofacial surgeons, 106 periodontists and112 general dentists selected their desired method for each of the ridges. Pearson chi square test was used for data analysis. Most of the participants in ridges1, 2 and 4 selected method number 1 (41.8 and 48 and 67.5% respectively). Majority of the participants in ridges number 3 and 5 chose method 2(50 and 28.4% respectively). The most suitable method for clinicians in each area can be useful in radiologist s measurement in CBCT slices.
