Abstract
OBJECTIVE: The use of cone-beam computed tomography (CBCT) for periodontal diagnosis and treatment plan is limited. The aim of this study is to compare the assessment of periodontal conditions and infrabony defects between conventional intraoral radiography (IOR) and CBCT.
METHODS: The study included 25 subjects who had periodontitis and at least 2 infrabony defects. All subjects received clinical periodontal examination, IOR, and CBCT. Three periodontists assigned periodontal diagnosis and prognosis of each tooth. For teeth with infrabony defects, the number of defect walls and treatment was determined. IOR and CBCT assessment was compared.
RESULTS: There were 666 teeth and 123 infrabony defects. The overall concordance between IOR and CBCT for periodontal diagnosis, prognosis, infrabony defect type, and infrabony defect treatment, were 79.3%, 69.5%, 44.7%, and 64.2%, respectively. IOR underestimated diagnosis, prognosis, and the number of infrabony defect walls at 16.4%, 24% and 37.4%, respectively. IOR and CBCT had poor concordance for periodontal regeneration (43.3%). Tooth extraction was more prevalent when assessed by CBCT (35.0% vs. 22.7%). CBCT had excellent inter-examiner agreement (Fleiss' kappa 0.87-0.94) and higher percentage of complete agreement among examiners than IOR for all assessments.
CONCLUSIONS: IOR underestimated the severity and prognosis of periodontal disease. CBCT was superior to IOR for evaluation of infrabony defect morphology and treatment. CBCT provides excellent agreement among examiners on periodontal and infrabony defect assessment.
