DIAGNOSTIC ACCURACY OF PERIAPICAL RADIOGRAPH, CONE BEAM COMPUTED
TOMOGRAPHY, AND INTRASURGICAL LINEAR MEASUREMENT TECHNIQUES FOR
ASSESSING FURCATION DEFECTS: A LONGITUDINAL RANDOMISED CONTROLLED TRIAL

Objectives: To evaluate the accuracy of cone beam computed tomography (CBCT),
periapical radiograph, and intrasurgical linear measurements in the assessment of molars
with furcation defects. Materials and methods: This parallel, single-blinded, randomised
controlled trial (RCT) consisted of 22 periodontitis patients who had molar with advanced
furcation involvement (FI). All patients followed the same inclusion criteria and were
treated following the same protocol, except for radiographic evaluation (CBCT vs.
periapical). This study proposed and evaluated five parameters that represent the extent
and severity of furcation defects in molars teeth, including CEJ-BD (clinical attachment
loss), BL-H (depth), BL-V (height), RT (root trunk), and FW (width). Results: There were no
statistically significant differences between CBCT and intrasurgical linear measurements
for any clinical parameter (p > 0.05). However, there were statistically significant
differences in BL-V measurements (p < 0.05) between periapical and intrasurgical
measurements in maxillary molars. Meanwhile, the sensitivity was 62.8% and 56.9% for
CBCT and periapical, respectively. Conclusions: Overall, when compared to the
intrasurgical measurements, CBCT provided better diagnostic, sensitivity, and
quantitative information on CAL, height, depth, and width of the furcation defects than
periapical radiograph. Clinical relevance: An accurate presurgical furcation diagnostic tool
can guide the clinicians from the stage of diagnosis to definitive management so that
unnecessary periodontal surgical interventions can be prevented.
