Supernumerary Teeth and Dental Development

Abstract

Purpose: The aims of this study were to compare the radiographic development of permanent teeth in a group of children with and without supernumerary teeth (ST), determine whether using conebeam computed tomography or panoramic radiography improves the accuracy of dental age (DA) estimation and investigate the effects of factors including the numbers and positions of ST. Methods: One hundred fifty dental radiographs of children with and without ST at the ages of 6.0 to 14.9 years were included in this study. The children in both groups were age and sex-matched. The lower left-side 7 permanent teeth were evaluated according to the Demirjian method, DA was determined. The difference between chronological age (CA) and DA (CA-DA) for the children with and without ST and further based on the number and localization of ST were calculated.Results: For all groups, the mean DA values were higher than the mean CA values. The difference between the CA and DA values in the children with ST was higher than the difference in the children without ST. Supernumerary teeth in posterior localization, multiple ST and among boys were observed to increase the differences between the mean CA and DA values. The mean age difference between radiographies in the children with and without ST was similar. Conclusion: Panoramic radiography was found adequate in determination of dental development with the Demirjian method. Dental development was even more advanced in the children with ST in comparison to the control group. Clinicians should keep in mind that the dental developments of children with supernumerary teeth may be advanced.

Technical Skills to Split Teeth During Extraction of Mesiodentes in High Site

“…Identifying the position and direction of mesiodens is essential. Compared to conventional imaging, CBCT can provide more accurate assessment, including the position, direction, morphology of mesiodens and condition of adjacent teeth 16 . CBCT is highly recommended for diagnosis of mesiodens.…”

Supernumerary tooth impacted close to the nasal cavity: Case report

“…In Latin America, mesiodens are the most frequent supernumeraries, with a prevalence of 1.7% [3] . Dental eruption of patients with supernumerary teeth is faster than chronological age, compared to patients without supernumerary teeth [4] . Mesiodens are the most frequent etiology of diastases at the midline level [5] .…”

Dente supranumerário em região de mandíbula: relato de caso

“…Enquanto uma arcada dentária humana permanente típica compreende trinta e dois dentes, a dentição decídua apresenta apenas vinte. Hiperdontia, também conhecida como presença excessiva de dentes, pode ser classificada como supranumerários rudimentares, quando sua anatomia difere dos padrões regionais, ou supranumerários suplementares, quando sua forma é similar aos demais dentes na região (1,2).…”
