Additionally, there were negative correlations observed for all sites except B and L/P sites; however, these were not statistically significant. Moreover, there were significant differences (<i>p</i> < 0.05) observed between anterior and posterior sites measured via CBCT except for the MB site. On the other hand, a comparison between anterior and posterior teeth measured via surgical interventions showed significant differences (<i>p</i> = 0.0001) in all measured sites.</p><p><strong>Conclusion: </strong>A significant correlation has been observed between measurements acquired from CBCT and surgical intervention for the anterior teeth. On the contrary, no significant correlation was observed for the posterior teeth.</p><p><strong>Clinical significance: </strong>Overlapping and the absence of 3D information are two of traditional radiography's main drawbacks. Surgerical exposure can yield precise information, but it gives less time to plan the kind of periodontal regeneration that will be needed. The accuracy and feasibility of CBCT have been established.
