The study sample comprised 3000 patients, 1220 (41%) males and 1780 (59%) females. The total number of missing teeth, excluding third molars, was found to be 518 (17%), discovered in 326 individuals (11%), 139 males (43%) and 187 females (57%) (Table 1). Those found to be missing from the maxillary dentition numbered 308 (59%), and those from the mandibular dentition 210 (41%). While 311 (95.4%) individuals had one to five missing teeth (Hypodontia patients), 15 (4.6%) had six to eleven missing permanent teeth (Oligodontia patients) (Two patients with 11 missing teeth; one with 9 missing teeth; one had 8 missing teeth; five had 7 missing teeth; and six patients had 6 missing teeth each). The most common missing tooth was the maxillary lateral incisor (176) (\(p\) < 0.05), of which 93 (53%) were the right lateral incisor, and 83 (47%) the left lateral incisor. The next most common missing tooth was the mandibular second premolar 137 (27%), 76 (55%) from the left side and 61 (45%) from the right (Table 2). A total of 73 (13%) maxillary second premolar teeth were found to be missing, 37 (51%) from the left and 36 (49%) from the right side (Table 3). Missing first premolars numbered 61 (12%), of which 34 (56%) from the maxilla and 27 (44%) from the mandible. \begin{table}

Table 1: Distribution of missing teeth by gender. A total of 41 (8%) canines were missing, 25 (61%) from the maxilla and 16 (39%) from the mandible. A total of 30 (6%) mandibular incisors were missing, distributing equally between right and left sides (Table 3). Bilateral agenesis of teeth was significantly more (131-80%) than unilateral agenesis (33-20%) (\(p<0.05\)). The most common bilateral agenesis were the maxillary lateral incisors followed by the mandibular second premolars (\(p<0.05\)) (Table 4). The patterns of bilateral agenesis of the maxillary lateral incisors and bilateral missing maxillary second premolars were detected in four individuals, while bilateral missing of the maxillary lateral incisors and bilateral missing mandibular second premolars in seven individuals. Bilateral agenesis of both maxillary and mandibular second premolars were found in nine individuals; and one individual showed a combined bilateral missing of the maxillary lateral incisors, bilateral missing maxillary second premolars and bilateral missing mandibular second premolar. Other dental anomalies detected in patients with tooth agenesis include: peg-shaped maxillary lateral incisors, supernumerary teeth, retained maxillary primary canines and impacted maxillary permanent canines, ectopic teeth, canine transposition and transmigration [1]. \begin{table}
