The cementodentinal junction (CDJ) forms a biological and structural link between cementum and dentin. This biological link is regarded as a distinct tissue in its own right. Certain important proteins responsible for periodontal regeneration are ...

2010年11月1日 · The results of this study presented an evaluation of the effect of CDJ and cementum and exhibited the association between the tooth attachment mechanism and the load transfer characteristics within the tooth supporting structure.

2007年12月1日 · Cementum is attached to root dentin via a hydrophilic fibrous cementum–dentin junction (CDJ) [8]. The CDJ is also known as the innermost cementum layer, intermediate cementum or collagen hiatus and consists of collagen fibrils and remnants of epithelial cells of Hertwig's epithelial root sheath (HERS) [9].

In this study the collagen fiber orientations defining the structure of cementum and CDJ are described relative to the longitudinal axis (Z) of a tooth. AFM, histology and MicroXCT results offer structure variations within transverse planes (2-D XY plane) assumed to be orthogonal to the longitudinal axis of a tooth.

2015年9月1日 · In the first phase of our study, the collagenous architecture of CDJ of healthy teeth has been reported. Aim: The objective of this study is to observe and report periodontal pathological...

A cemental tear can be either the incomplete or complete detachment of the cementum from the cemento-dentinal junction (CDJ) or its partial detachment along the incremental line within the body of cementum of the tooth root (Watanabe et al., 2012).

2022年11月6日 · The CDJ is a structure that can be observed in histological sections; however, clinically and radiographically, locating the CDJ is impossible. The cementum extends into root canals by covering dentine and the CDJ is located at various levels around the circumference of the canal wall in the region of the apical foramen.

Aim: The objective of this study is to observe and report periodontal pathological changes in the fibrous or collagenous architecture of CDJ of periodontitis-affected teeth and discuss the probable clinical implications of CDJ in disease.

Cementum is attached to root dentin via a hydrophilic fibrous cementum-dentin junction (CDJ) [8]. The CDJ is also known as the innermost cementum layer, intermediate cementum or collagen hiatus and consists of collagen fibrils and remnants of epithelial cells of Hertwig’s Epithelial root sheath (HERS) [9].

The border between cementum and dentin, the Cementum-Dentin junction (CDJ), is less distinct than the DEJ. Cementum is slightly less strong than dentin, and is composed of the materials listed in Table 4.5. Some publications list the mineral component of cementum to be 60 to 65% (further reading here).
