Congenital absence of the permanent canines: a clinico-statistical study

Abstract

Abstract:We report here a clinico-statistical study of congenital absence of the permanent canines (CAPC). Sixty-five cases (22 men and 43 women) of CAPC were found in the files of 35,927 outpatients, an incidence of 0.18%. Thirty-seven cases had single absence of the canine and 28 cases had multiple absences. There were 42 cases in the maxilla, 17 in the mandible, and 6 in both the maxilla and the mandible. In the single absence cases, there was a tendency of occurrence at the left side in the maxilla, and the right side in the mandible. There were 39 CAPC cases without absence of other permanent teeth. Several complicated dental anomalies were seen such as persistence of deciduous teeth, congenital absence of other permanent teeth, microdontia, malposition, and complete or incomplete impaction (excluding the third molars). The complication rate of other permanent tooth absences was higher in the cases with CACP in the maxilla than in the mandible. (J. Oral Sci. 46, [247][248][249][250][251][252] 2004)

Non Syndromic Familial Hypodontia - A Case Series

“…The most frequently affected teeth are the mandibular second premolar and the maxillary lateral incisor [4]. The congenital absence of canines in the permanent dentition is reportedly a very rare occurrence with prevalence rates varying from 0.06% to 0.18% [11]. The present cases report familial non-syndromic hypodontia in three siblings, of which two cases show bilateral maxillary canine agenesis.…”

Bilateral Mandibular Permanent Canine Agenesis: A Rare Case Report

“…[8] Fukuta et al in their study showed that male to female ratio affected by congenital absence of permanent canine was 1:2, with left side of maxilla and in the mandible right side being affected more. [7] The association of dental agenesis with syndromes and dental anomalies have also been reported in literature. These include Rieger syndrome, Witkop syndrome, Book syndrome, Down syndrome, oral and facial clefts, hemifacial microsomia and many others.…”

“…[7] The incidence of congenitally missing permanent canine was found to be 0.1% in the maxilla and 0.02% of mandible in a survey of congenitally missing teeth, excluding third molar in 6000 orthodontic patients by Rose. [8] Fukuta et al in their study showed that male to female ratio affected by congenital absence of permanent canine was 1:2, with left side of maxilla and in the mandible right side being affected more.…”

A rare case of congenital absence of permanent canines associated with other dental anomalies

“…Congenital absence of the canines in the permanent dentition is very rare and the reported incidence varies from 0.18 -0.45% (3,4,5). Studies have reported more predilections in females and in the maxilla (3,4). Dental anomalies associated with congenitally missing permanent canines include agenesis of other teeth, microdontia, malocclusion, and retained primary teeth (4).…”

“…Prevalence of hypodontia in the permanent dentition (excluding 3rd molars) is about 4.5 -7.4% in Caucasians (1) and the most frequently affected teeth are the mandibular second premolar (3.4%) and the maxillary lateral incisor (2.2%) (2). Congenital absence of the canines in the permanent dentition is very rare and the reported incidence varies from 0.18 -0.45% (3,4,5). Studies have reported more predilections in females and in the maxilla (3,4).…”
