“…For the root perimeter, the same procedure was carried out but at the cementoenamel junction (CEJ) [21] (Figures 3 & 4). The palatal height was measured from the midpalatal suture, tracing a perpendicular line to the line formed from central fossa to central fossa of the upper first molars [26]. To measure the angulation of the first upper molars, a straight line was drawn parallel to the palatal base and then a perpendicular line was drawn to this one passing through the centre of the pulp chamber of both upper molars [27] (Figure 5).…”
