Frequency of impacted teeth and categorization of impacted canines: A retrospective radiographic study using orthopantomograms

Abstract

Objective:The objective of this study is to determine the frequency of impacted maxillary canines using seven subtype classification system. For this purpose, impacted maxillary canines have been divided into seven various subtypes.Materials and Methods:This is a descriptive, cross-sectional, and retrospective study conducted using radiographic data of residents of Madinah, Al Munawwarah. Radiographic data of 14,000 patients, who attended College of Dentistry, Taibah University, from January 2011 to February 2015, were screened against the selection criteria for the presence of impacted teeth. The individuals with maxillary impacted canines were matched to maxillary canine impaction. The occurrence of each subtype of impacted canines was calculated.Results:Impacted teeth are more common in the maxilla compared to mandible. The impacted canine represented the highest proportion of all impacted maxillary teeth followed by the second premolars and the central incisors. According to the classification system represented, Type II of canine impaction comprised the highest proportion (51%) while Type IV (0.5%) comprised the lowest frequency. The maxillary canine is the most frequently impacted tooth followed by mandibular canines.Conclusions:Although there are many variations, the majority of impacted canines fall into Type II of the classification of impacted canines.

Radiographic assessment of impacted maxillary canine position using CBCT: A comparative study of 2 methods

“…In our study, a higher incidence of impacted maxillary canines was found in females (83.3%) as compared to males (16.7%). This was in concordance with many previous studies that showed that these impactions are more com monly found in female patients than in males with a 2:1 ratio 4,6,15,17,[21][22][23] . A typically similar result to ours was found by Zarch et al at 2013 where the majority of their patients were females (80%).…”

“…An almost equal distribution of impacted maxillary canines was found in our results on both sides (23 on the right (51%) and 22 on the left (48.9%) side). Nevertheless, Al Zoubi et al at 2017 reported a higher prevalence of impacted maxillary canines on the left side compared to the right side 23 . Similarly, a previous study by Takahama and Aiyama at 1982 reported a higher frequency of left sided maxillary impactions in cleft patients as well as in the control group.…”

Analysis of X-Ray Features of the Location of Impacted Teeth in the Examined Patients

“…Ретеновані зуби -досить поширена патологія у осіб молодого віку, яка потребує виваженого підходу до проведення діагностики та вибору методу лікування, адже правильне ведення таких пацієнтів призводить до позитивного результату, що призводить до відновленні цілісності зубних рядів, та відповідно повноцінної естетики та функціонування зубощелепного апарату [4,6,10,15]. У алгоритмі обстеження обов'язковим є встановлення положення вісі ретенованого зуба в щелепі та по відношенню до вісі сусідніх зубів, стан альвеолярної кістки, вік пацієнтів та їх загальносоматичний статус [8,9,[11][12]14]. Вибір методу лікування: ортодонтичне, хірургічне та комбіноване, з додатковим використанням пародонтальної хірургії та фізіотерапевтичного лікування повинен проходити індивідуально з подальшим моніторингом та диспансерним наглядом.…”

A Radiograhic Study of the Third Molar Inclusion

“…(1) Even if the frequency of impacted teeth among individuals varies from country to country, the third molar remains the most common tooth aff ected by impaction, followed by the maxillary canine. (2) Factors that can infl uence dental impaction can be systemic and local. Among the local factors we can mention the lack of space on the arch, the premature loss of deciduous teeth, the ectopic position of the dental bud, obstructions along the path of the eruption, dental crowding or cystic tumours.…”
