THE ACCURACY OF LINEAR MEASUREMENTS IN CONE BEAM COMPUTED TOMOGRAPHY
FOR ASSESSING INTRABONY AND FURCATION DEFECTS: A SYSTEMATIC REVIEW AND
META-ANALYSIS

Yusof NAM, Noor E, Yusof MYPM
Objective: To assess the accuracy of the linear measurements of intrabony and/or
furcation defect quantified by cone beam computed tomography (CBCT). Materials and
methods: A systematic search of the literature was conducted by two authors
independently from the PubMed, Scopus, and EBSCO for full articles published in journals
between January 2003 and March 2017. Eligible studies were assessed for quality and
heterogeneity using the QUADAS-2 tool. A meta-analysis was performed to identify the
accuracy of CBCT in the measurement of intrabony defects. The effect size was estimated
and reported as the standardised mean difference (SMD). Results: A total of 105 titles and
abstracts were screened. Of those, 11 articles met the inclusion criteria for the systematic
review while only four were selected for meta-analysis. The overall effects of standardized
2
mean difference and 95% CI was -0.03 [95% CI -0.67 to 0.60] with a x statistic of 0.49 with
three (3) degrees of freedom (p>0.05), I2= 0.01%. Conclusion: CBCT is highly accurate and
reproducible regarding linear measurements for assessing intrabony defects with a
weighted standardized mean difference of 0.03mm. More randomised controlled trials
are required to assess the accuracy of CBCT in assessing patients with periodontal defects.
