Diagnostic Accuracy of CBCT for Detection of Second Canal of Permanent Teeth: A Systematic Review and Meta-Analysis

Table 3

Sensitivity and specificity of CBCT for detection of different types of permanent teeth except for mandibular canine.

Second canal	MB2	Maxillary and mandibular premolars	Mandibular molars
Pooled prevalence (%)	59	29	63
Sensitivity (95% CI)	96.6% (82.5%–99.4%)	88.8% (40.7%–98.9%)	81% (73.2%–86.9%)
Specificity (95% CI)	85.1% (65.2%–94.6%)	97.6% (94.8%–98.9%)	85.7% (76.5%–91.7%)

MB2: second mesiobuccal canal of permanent maxillary first and second molars: %: percentage; CI: confidence interval; pooled sensitivity and specificity of mandibular canine cannot be estimated because MetaDTA software allows at least two studies to undergo meta-analysis.
