“…In the literature survey performed during this study, 12 articles reported an association between TT and agenesis 3,4,9,11,13,14,17,20,54,55,62,64 but none described the occurrence of tooth giroversion. The reported frequency of the association between TT and agenesis in previous studies was around 37-40% 16,65 . In addition, retained canine was one of the most common dental anomalies found in combination with TT (Table 1), and this may suggest a common etiological origin for these conditions.…”

Tooth transposition is a rare developmental disorder in which a normal tooth erupts in an inappropriate position. The change in position occurs between two adjacent teeth within the same quadrant. In this article, two cases of tooth transposition involving mandibular molars are described. Patient 1 presented with bilateral transposition between first and second mandibular molars. In addition, giroversion of the first molars was observed. Patient 2 presented with unilateral transposition between the mandibular left molars. Because this tooth disorder does not affect quality of life, both patients declined to seek dental treatment. Out of the 120 cases of tooth transposition found in the literature, 92,5% occurred in the maxilla and 15% were bilateral, 65,8% percent of these cases involved the canine and first premolar; 26.6% involved the canine and lateral incisor; 2,5% involved the canine and central incisor; and only 0.85% involved the first and second molar. The majority of tooth transposition cases occurred in women (66,6%). In literature, tooth transposition is a poorly-documented condition. Consequently, this report seeks to contribute to the existing information in the literature on this disorder.

“…TT can occur at any age and is usually diagnosed during clinical and radiographic examination, prior to orthodontic treatment. The distribution of TT cases by sex varies according to the geographical location 1,65,66 . It can affect the maxillary or mandibular dentition, unilaterally or bilaterally 66 .…”

“…Radiologic examination complements clinical examination by demonstrating complete dental inversion in the case of total transposition, tooth overlap, or root inversion in partial transposition. 28 The most frequent tooth diagnosed with dental transposition is the maxillary canine that can change its place with the lateral incisor or first premolar (►Fig. 5).…”

Dentists and oral and maxillofacial radiologists have used periapical, occlusal, panoramic, and cephalometric radiographs for many years for diagnosing dental anomalies, especially before orthodontic or surgical treatment. Cone beam computed tomography was developed in recent years especially for the dental and maxillofacial region. Thus it has become the imaging modality of choice for many clinical situations, such as the assessment of dental impaction and structural teeth anomalies or other associated diseases and disorders (e.g., Gardner's syndrome, cleidocranial dysplasia). This article reviews different aspects of dental impaction and its possible effects on adjacent structures such as external root resorption, marginal bone loss, as well as describing structural dental anomalies. It provides a systematic analysis of their characteristic features and imaging findings for general radiologists to achieve a precise diagnosis and an optimal interpretation.

“…When the affected teeth are completely transposed, complete transposition is observed. If the roots remain in a normal position with only transposed crowns, incomplete transposition is defined [ 13 ]. Tooth agenesis is most commonly observed in patients with CLCP [ 14 , 15 ].…”

The aim of this study was to investigate the prevalence of tooth agenesis, tooth malformation, and eruption patterns of upper canines/first premolars in Taiwanese children. A total of 132 cleft lip and cleft palate (CLCP) patients (82 boys and 50 girls) underwent alveolar bone grafting (ABG) between 2012 and 2022. The patients’ dental records and X-ray images were inspected. We examined dental anomalies, including congenital missing teeth, microdontia, and transposition from the upper canines to the upper first premolars in these CLCP patients. Additionally, we investigated the mean ABG operation age (9.27 ± 0.76 years) of our patient; 40.9% of them received pre-ABG orthodontic treatment at 8.72 ± 0.70 years. Among the 132 cleft subjects, the prevalence of tooth agenesis is 73.5% (97/132). The most frequently missing teeth are the maxillary lateral incisors (right side: 46.2%; left side: 47.0%). In this study, microdontia are found in all the upper incisors, of which the highest percentage (18.9%) is observed in the upper left lateral incisors. The prevalence of upper canine and first premolar transposition is 10.6%. The pattern of tooth agenesis and microdontia of the upper lateral incisors shows a strong correlation with the cleft sites of these CLCP patients in our study. These results may support the idea that the patterns of dental anomalies in CLCP patients are region-specific.
