Anatomical Configuration of Roots and Canal Morphology of Primary Mandibular First Molars: A CBCT Study

A critical analysis of laboratory and clinical research methods to study root and canal anatomy

“…The knowledge generated on root and canal anatomy in the primary dentition is mainly from laboratory studies using 2D radiographic imaging (Gupta & Grewal, 2005; Sarkar & Rao, 2002), staining and clearing (Bagherian et al, 2010; Gupta & Grewal, 2005; Katge & Wakpanjar, 2018), SEM (Dammaschke et al, 2004; Sharma et al, 2016), 2D radiographic (periapical [Song et al, 2009] or vertical bitewing [Liu et al, 2010; Tu et al, 2010]), CT (Zoremchhingi et al, 2005), CBCT on extracted teeth (Demiriz et al, 2018; Gaurav et al, 2013; Reddy et al, 2018) and micro‐CT (El Hachem et al, 2019; Fumes et al, 2014; Mohd Ariffin et al, 2020; Neboda et al, 2018; Wang et al, 2013; Ziya et al, 2019) (Figure 41). In addition, clinical CBCT in population groups such as Chinese (Yang et al, 2013), Korean (Jung et al, 2020), Turkey (Ozcan et al, 2016) and India (Krishnamurthy et al, 2017) have been the most commonly used methods for clinical studies.…”
