Tooth number – FDI tooth numbering system; M – Males; F – Females; T – total; 14, Maxillary right first premolar (MFP), 24, Maxillary Left first premolar (MFP), 15, Maxillary right second premolar (MSP), 25, Maxillary left second premolar. Type I, 1 canal from the orifice to the apex represented as 14 1 root with 1 canal according to Ahmed et al. Type II, originates as 2 canals, merges, and ends as 1 at the apex represented as 14 1 root with 2 canals at the beginning and ending as 1 at the apex according to Ahmed et al. Type III, 1 canal at the orifice divides into 2 along its length and then merges into 1 before exiting the root at the apex represented as 14 according to Ahmed showing 1 root with 1 canal which divides into 2 along its length then merges into 1 before exiting the apex. Type IV, originates as 2 canals and ends as 2 at the apex represented as 25 according to Ahmed et al showing 1 root with 2 root canals and 14BP showing 2 roots with separate canals in each buccal (B) and palatal (P) roots. Type V, originates as 1 canal then divides into 2 along its length and exits the root represented as 14 according to Ahmed et al showing 1 root with 1 canal in the coronal third then dividing into 2 before exiting the apex. Type XVI, Sert and Bayirli addition to Vertucci represented as 14BP according to Ahmed et al showing 2 roots with buccal root (B) having 1 canal in the coronal third and then dividing along its length and exiting as 2 while the palatal root (P) having 1 canal throughout its length. Type VIII, originates as 3 and ends as 3 canals at the apex represented as 14MBDBP according to Ahmed et al showing 3 roots with single canals in each mesiobuccal (MB) distobuccal (DB) and Palatal (P) roots. χ – Chi-square test; ns – non-significant with value ≤0.05. |
