Bir Grup Türk Populasyonunda Görülen Meziodenslerin Sıklığı, Özellikleri Ve Meydan Getirdikleri Komplikasyonlar

Objectives: the purpose of the study was to analyze the frequency, characteristics and associated complications of mesiodens in a group of patients in Turkey.

Materials and Methods: The present study included 3782 patients (1590 male, 2192 female), who attended the Department of Maxillofacial Radiology, Faculty of Dentistry, Erciyes University for their dental problems. Panoramic radiographs routinely obtained during dental examinations served as the study basis for detection of the prevalence of mesiodens. In the case of mesiodens detection additional occlusal radiographs were obtained from the patients. In addition to age and gender, descriptive characteristics of meziodens, including number, shape, position, complication caused by mesiodens were recorded.

Results: The prevalence of mesiodens in the present study was 2.7% (3.9% male, 1.8% female). The sex ratio was 2.17:1, favoring boys, the ratio was statistically significant (p<0.001).The majority of the mesiodens (50%) were conical in shape. A majority of the mesiodens (62.1%) were vertically aligned. Inverted and horizontally positions were observed in 20.2% and 16.1% of the cases. 17 patients had two, and two patients had more than two mesiodens. Most of the mesiodens (58.1%) were associated with complications and only 41.9% were asymptomatic.

Conclusions: The prevalence of mesiodens was found to be high comparable to similar studies in the literature. The majority of the mesiodens were impacted and thus, in case of retention or delayed eruption, dentists should bear in mind that mesiodens may be the cause and early detection and timely surgical intervention should be kept in mind to avoid unwanted complications.
