    Investigation of prevalence and characteristics of mesiodens in a non-syndromic 11256 dental outpatients
    (Verduci Publisher, 2013) Colak, H.; Uzgur, R.; Tan, E.; Hamidi, M. M.; Turkal, M.; Colak, T.
    AIM: To investigate the prevalence of mesiodens in a sample of Turkish dental patients and their distribution among genders. PATIENTS AND METHODS: A retrospective study was performed using panoramic radiography of 11256 patients, who ranged in age from 15 to 55 years old. All data (age, sex and or syndrome) were obtained from the patient files and analyzed for mesiodens. Statistical evaluation of the presence of mesiodens related to gender was performed by the Pearson chi-squared test. RESULTS: Mesiodens was detected in 15 subjects (0.13%). The prevalence of mesiodens for females and males was 0.20% and 0.057%, respectively (p = 0.037). The most commonly observed mesiodens was maxillary canine-like type (60%). Most of the mesiodens (67%) were found in the vertical position, followed by horizontal position (33%). The age and sex distribution, number of mesiodens per patient, shape, direction, size, and effect on permanent maxillary incisors are also presented in this study. The most common complication caused by mesiodens was midline of the permanent incisors. CONCLUSIONS: Mesiodens is an uncommon developmental anomaly in Turkish dental patients. Early diagnosis allows the most appropriate treatment, often reducing the extent of surgery, orthodontic treatment and possible complications.

    Prevalence of Root Dilacerations in Central Anatolian Turkish Dental Patients
    (Univ West Indies Faculty Medical Sciences, 2012) Colak, H.; Bayraktar, Y.; Hamidi, M. M.; Tan, E.; Colak, T.
    Objective: The aim of this study was to determine, retrospectively, the prevalence and distribution of the dilaceration of the root for each tooth-type in a sample of Central Anatolian Turkish population by using panoramic radiographs. Method: Panoramic radiograhs of 6912 patients (3860 women and 3052 men, mean age 29.04 years, range, 15 to 50 years) were examined for the presence of root dilacerations. Chi-square test was also used to compare the prevalence of dilacerations between male and female subjects and upper and lower jaws. Results: Data showed that 1108 (16.0%) of these subjects had one or more teeth that were dilacerated and these were detected in 466 (15.2%) males and 642 (16.6%) females. Statistical analysis (chi(2) test) showed a significant difference in the prevalence of dilaceration among male and female patients. Mandibular third molars were dilacerated most often (3.76%), followed by mandibular second molars (1.81%). Dilaceration was found in 1.23% of maxillary second premolars and 1.23% of mandibular second molars. Conclusion: Root dilacerations are not uncommon among Turkish dental patients, and their early detection could be important in treatment problems associated with it. However, further larger scale studies are required to assess its prevalence in the general population in order to compare it with other ethnic groups.
