“…27 The prevalence of SRA in the Finnish population is 1.3%. 41 In our study the defect categories D2 and D3 fulfill the criteria of short root anomaly. In the TBI group 10/10, and in the non-TBI group 1/5 patients had alterations of this magnitude in relative root length, giving a prevalence of 73.3%.…”

Summary:Chemo-and radiotherapy may have injurious effects on developing teeth. In this long-term follow-up study among poor-risk neuroblastoma (NBL) survivors our aims were: (1) to assess both the type and extent of the side-effects of the anticancer treatment on tooth development; and (2) to develop an index for expressing total damage to the permanent dentition. We studied the dental development from panoramic radiographs (PRG) of 18 long-term survivors treated under the age of 6 years with high-dose (HD) chemotherapy and autologous stem cell transplantation (ASCT) for poor-risk NBL. The myeloablative therapy was either HD chemotherapy and fractionated total body irradiation (TBI) of 10-12 Gy (TBI group, n = 10) or HD chemotherapy only (non-TBI group, n = 8). A defect index (DeI) was developed to describe the damage to the permanent dentition. The DeI was also tested in 18 healthy adolescents. All NBL patients had disturbances in dental development including short roots, arrested root development, microdontia and tooth aplasia. After TBI, 9/10 patients had very severe root defects, in contrast to none in the non-TBI group. All children in the TBI group had 2-12 (mean 6.6) missing permanent teeth, while 2/5 in the non-TBI group (3/8 excluded due to young age) had two and four missing permanent teeth, respectively. Microdontia was found at equal frequency in both groups. The mean value of the DeI was 70.0 (range 28-117) in the TBI group, 15.2 (range 4-34) in the non-TBI group (P Ͻ 0.001, Mann-Whitney U test) and 1.8 (range 0-15) in healthy adolescents. Disturbances in dental development may compromise occlusal function in poor-risk NBL patients after ASCT, especially when TBI is included in the conditioning regimen. Long-term dental follow-up and rehabilitation is required.

“…This racial variation, together with a strong familial background, indicates that this anomaly has a strong genetic influence (16). Apajalhti et al (19) found a prevalence of 1.3% among healthy young adults. The male:female ratio is reported to be 1:3 (19).…”

“…Apajalhti et al (19) found a prevalence of 1.3% among healthy young adults. The male:female ratio is reported to be 1:3 (19). Presence of generalized short roots was found in combination with systemic conditions such as hypoparathyrodism, Stevens-Johnson syndrome, Rothmund-Thomson syndrome, exposure to irradiation and thalassaemia disorders (16)(17)(18).…”

Permanent mandibular central incisor is rarely affected by tooth shape anomalies of crown and root. Co-occurrence of multiple anomalies in a permanent mandibular central incisor is extremely rare. This paper reports an unusual concurrent combination of multiple dental anomalies affecting both the crown and root of a permanent mandibular left central incisor -talon cusp, dens invaginatus, short root anomaly and macrodontia -, which has not previously been reported together. Case management is described and implications are discussed. The dentist should be aware of these rare entities in order to provide an accurate diagnosis and management for which detailed examination of the tooth both clinically and radiographically is very important.

“…The condition designated as short root anomaly or SR anomaly (Lind, 1972) occurs mostly in maxillary central incisors (Apajalahti et al, 2002) and is described in modern clinical literature (de Man, 1979;Apajalahti et al, 2002;Roinioti and Stefanopoulos, 2007). According to Turp and Alt (1998), variations in the root size and form of permanent teeth are determined by separate hereditary factors; however, tooth germ distortion or injury by trauma is also a possible origin of short roots (Hillson, 2005).…”

Leprogenic odontodysplasia: new evidence from the St. Jørgen’s medieval leprosarium cemetery (Odense, Denmark)

Leprogenic odontodysplasia (LO), also known as dens leprosus, consists of anomalous root development of the permanent upper incisors. This dental anomaly was first reported by Danielsen in 1968 among Danish juvenile skeletons from medieval leprosaria cemeteries. As yet, no clinical cases have been documented and the etiological and epidemiological significance of the condition are poorly understood. The aim of this study is to discuss a case of LO found amongst the skeletons from the St. Jørgen's leprosarium cemetery (13th-16th/17th centuries), housed in the ADBOU (Anthropological Database of Odense University), Southern Denmark University. A juvenile individual presents a disarticulated maxillary right central incisor possessing a short root that shows a groove caused by marked constriction beginning approximately 1.5 mm above the neck. From this groove, the diameter decreases considerably until the apex. Atrophy of the anterior alveolar maxillary process, extending laterally from the central incisors to the canines, is also apparent. This individual exhibits additional rhinomaxillary lesions (e.g. absorption of the piriform margin including the anterior nasal spine) and foot changes (including phalangeal acro-osteolysis) compatible with a diagnosis of lepromatous leprosy. This case contributes to the debate about the significance of this rare condition, particularly in terms of its presence in Scandinavian skeletons from medieval leprosaria cemeteries. Possible interpretations are discussed, including the pathognomonic value of the specific lesion and whether it indicates early childhood onset of leprosy during the Middle Ages. The understanding of LO epidemiology and its relationship with leprosy will benefit from future clinical and skeletal studies.
