“…In our study, we found the mesioangular impaction is the most common type of impaction in both unilateral 39% and bilateral impactions 41%, respectively. Our study result shows similar results found in various other studies [ 14 – 16 , 18 ] and international studies [ 11 , 15 , 31 – 34 , 36 ]. Bokhari et al [ 16 ] mentioned about Belfast Study Group in their article.…”

“…Higher prevalence of mesioangular impaction may be related to the more common underdevelopment of mesial root. But we found vertical angulation is not so far behind, unilateral 39% and bilateral impactions 39%, respectively, Alfadil and Almajed [ 18 ] also got similar results in their study. A previous study conducted in the same region by Haidar and Shalhoub [ 17 ] noted more frequency of vertical impaction 53.9% followed by mesioangular 32.7%.…”

“…This is the third study to evaluate incidence of impacted third mandibular molars in the population of the Central Region of Saudi Arabia. Previous two studies were conducted 35 years and two years ago, respectively [ 17 , 18 ]. The number of patient's radiographs in our study was equivalent or more to the number of radiographs used in many other national and international studies [ 14 – 18 , 23 – 38 ], and inclusion and exclusion criteria of patients were almost similar like other studies which allowed us to compare our results with such studies.…”

“…Haider and Shalhoub [ 17 ] reported 34% and 29% prevalence of impacted third molars for males and females, respectively. Alfadil and Almajed [ 18 ] reported 30.9% patients had at least one impacted third molar. This discrepancy perhaps is due to the higher number of patients considered for our study.…”

“…In Saudi Arabia, the pattern of third molar impaction has been assessed in several other regions [ 14 – 16 ], excluding two studies by Haidar and Shalhoub [ 17 ] and Alfadil and Almajed [ 18 ] which were conducted in the central region 35 years ago and two years ago, respectively. Haidar and Shalhoub [ 17 ]evaluated 1000 panoramic radiographs and reported 32.3% for third molar impaction incidence without any sex predilection.…”

The objective of this study was to study the incidence of type of impaction of mandibular third molars based on the classifications of Pell and Gregory and Winter, which included angulation of the tooth and level of the occlusal surface of the third molar with respect to the second molar, respectively, in a sample of Saudi population in central region. In this retrospective study, orthopantomograms (OPGs) of 17760 patients were examined, who were reported by the Dental University Hospital (DUH) at King Saud University, Riyadh, Saudi Arabia, between the years 2016 and 2020. Out of 17760 radiographs, 2187 (12.31%) patients presented with at least one impacted third molar. Out of which, 1337 (7.52%) patients had bilateral impaction and 850 (4.78%) patients had unilateral impaction ( p < 0.001 ). No gender predominance was noted in the impaction status ( p > 0.05 ). In bilateral impaction, 671 were male (50.2%) and 666 were female (49.8%). Among unilateral impaction, 394 (46.4%) were male and 456 (53.6%) were female. Mesioangular angulation was the most common pattern of impaction (65%) followed by vertical angulation in both bilateral and unilateral impactions. Level A impaction was found to be highest in both bilateral and unilateral impactions which are 48.02% and 54.0%, respectively ( p < 0.05 ). Our study highlights mesioangular impaction and level “A” as the most frequently encountered angulation and level of impaction in impacted teeth. This study result provides us useful data regarding the radiographic status of mandibular third molars in the population of Saudi Arabia.
