TABLE o1: Locations of defective secondary dentinal areas in diseased mandibular (mand) and maxillary (max) cheek teeth (CT) expressed as a percentage of the total number of Ct with defective secondary dentine.
Chart o1: A comparison of eruption age distributions of mandibular cheek teeth from cases and controls.
Chart o2: A comparison of eruption age distributions of maxillary cheek teeth from cases and controls.
Fig o1: Occlusal anatomy of mandibular cheek tooth (CT) of Triadan positions 06 (a) and also of maxillary CT of Triadan positions 06 (b). The locations of the dark-staining secondary dentinal areas are assigned names related to their anatomical location for the purposes of this paper. The endodontic numbering systems of Dacre (2005) ( ) and du Toit et al. (2008b) (*) are also illustrated. (This is an addition to Fig 2 in the paper, which demonstrated the the occlusal anatomy of teeth of Triadan positions 07–10.)
Fig o2: Of the 8 diseased mandibular cheek teeth from Triadan positions 07–10 with multiple secondary dentinal defects, the 2 most prevalent combinations of defective secondary dentinal areas were the combination of rostral buccal (RB) and caudal buccal (CB) and the combination of caudal buccal (CB) and caudal lingual (CL) areas. (“Rst” = rostral, “Buc” = buccal, “Cd” = caudal, “Ling” = lingual).
Fig o3: Fissure line running through the buccal aspect of a mandibular cheek tooth, connecting the rostral and caudal buccal secondary dentinal areas (arrows), which are defective.
