The Frequency and Characteristics of Mesiodens in a Turkish Patient Population

Abstract

Objectives:The aim of this study was to investigate the frequency and characteristics of mesiodens among a group of orthodontic patients in Turkey.Methods:A retrospective study was performed using panoramic radiographs of 3,351 patients ranging in age from 8 to 16 subjected to dental treatment in the Department of Oral and Maxillofacial Radiology and Department of Orthodontics (Erzurum, Turkey) between 1996 and 2008. All medical and demographic data (age and sex) were obtained from the files. Descriptive characteristics of mesiodentes, including number, shape, position, complication caused by mesiodens and treatment were recorded. The Chi-squared test was used.Results:Results show that the frequency of mesiodens was 0.3% with the ratio of boys (6 cases) to girls (4 cases) being 1.5:1 and this was not statistically significant (P>.05). Of the 10 children, 8 (80.0%) had 1 mesiodens and 2 (20.0%) had 2 mesiodentes bilaterally to midline. Of the 12 mesiodentes, 8 (66.7%) were fully impacted, 7 (58.3%) in a vertical position and 9 (75.0%) conical shape. The most common complication caused by mesiodens was delayed eruption of the permanent incisors in 4 cases (40.0%).Conclusions:The frequency of mesiodens in Turkish orthodontic patients was found to be 0.3% and more frequently in males with the ratio being approximately 1.5:1. Most of the mesiodentes were in conical shape (75.0%). Sixty-seven percent of the cases were fully impacted.

Radiographic characteristics of mesiodens in a non‐syndromic pediatric population in the Black Sea region

“…The reason for this is that the supplemental teeth in the form of natural teeth are often confused with permanent teeth, and the patient's family might think that the central teeth have erupted. 11 The majority (76.8%) of the mesiodens in the current study were in the vertical position, consistent with previous studies. Of the 82 mesiodens, 65 were vertical (76.8%), nine were inverted (12.1%), and eight were horizontal (10.9%).…”

“…They can be categorized as single (one mesiodens) or multiple (2, 3, or 4 mesiodens) . Gündüz et al, Kazancı et al, and Kocatas Ersin et al found one mesiodens in 76.8% of patients, and two mesiodens in 23.1%, one in 80%, and two in 20%, and one in 41.72% and two in 58.82% of patients, respectively . In the present study, one mesiodens in 84.5% (N = 60) of patients and two mesiodens in 15.4% (N = 11) of patients were found, and more than two mesiodens were not found in any of the patients.…”

“…Studies on the prevalence of mesiodens have shown that the rate varies between 0.15% and 2.2%. In studies conducted in Turkey, Gündüz et al, Bereket et al, Kazancı et al, and Colak et al reported the prevalence of mesiodens to be 0.3% in 23 000, 0.3% in 111 293, 0.3% in 6154, and 0.13% in 11 256 pediatric patients, respectively . Kara et al found a mesiodens prevalence of 0.27% in a multicenter study involving 35 108 patients .…”

“…In the present study, and contrary to the literature, the supplemental tooth rate was much higher in permanent dentition than the primary dentition, and much of it had erupted. The reason for this is that the supplemental teeth in the form of natural teeth are often confused with permanent teeth, and the patient's family might think that the central teeth have erupted …”

“…The mean age of patients with mesiodens in the present study (82.52 ± 12.67 months) was similar to that in previous studies. Children in this age group generally undergo assessments for normal tooth eruption and treatment for delayed or failed eruption of the maxillary central incisors; therefore, mesiodens is commonly discovered during this period.…”
