Assessment of coherence between the experts in interpreting the results of treatment of congenital cleft alveolar bone by Cone-Beam computed tomography

The aim of the study was to evaluate the agreement between the experts in evaluating the results of alveoloplasty in patients with congenital alveolar cleft with cone-beam computed tomography (CBCT). The study design: we evaluated the results of alveoloplasty of 79 patients. Interobserver agreement the radiologists was assessed be means of Cohen’s kappa. Diagnostic significance of the results was assessed using Student’s t-test. Results. In 35 (31%) cases type I to Bergland, type II was defined in 40 (35,4%) cases, type III in 30 (26,5%) cases and type IV ‒ in 8 cases (7,1%). Interobserver agreement of the experts is significant (k = 0.696 (p <0.001)).
