A retrospective study on molar furcation assessment via clinical detection, intraoral radiography and cone beam computed tomography

Table 6 Correlation coefficients of periodontal probing with CBCT or BW/PA in assessment of furcation involvement for maxillary and mandibular first molars

Periodontal charting (Modified Glickman)	CBCT	BW/PA
Maxillary buccal	0.599^a	0.579^a
Maxillary mesial palatal	0.591^a	0.499^a
Maxillary distal palatal	0.644^a,c	0.424^a,c
Mandibular buccal	0.372^a	0.362^a
Mandibular lingual	0.264^b	0.230^b

Abbreviations: CBCT cone beam computed tomography, BW/PA bitewing/periapical radiographs
^aCorrelation is significant at p < 0.01, between CBCT and periodontal charting, or between BW/PA and periodontal charting
^bCorrelation is significant at p < 0.05, between CBCT and periodontal charting, or between BW/PA and periodontal charting
^cCBCT demonstrated significantly stronger correlation (p < 0.05) with periodontal charting relative to BW/PA at assessment of distal palatal side of maxillary first molars
