    Malocclusion prevalence and orthodontic treatment need in central Anatolian adolescents compared to European and other nations’ adolescents
    (Dental Press Editora Ltda, 2015) Bilgic, Fundagul; Gelgor, Ibrahim Erhan; Celebi, Ahmet Arif
    Objective: To determine the prevalence of malocclusion and orthodontic treatment need in a large sample of Central Anatolian adolescents and compare them with European-other nations’ adolescents. Methods: The sample included 1125 boys and 1204 girls aged between 12 and 16 years with no previous orthodontic treatment history. Occlusal variables examined were molar relationship, overjet, overbite, crowding, midline diastema, posterior crossbite, and scissors bite. The dental health (DHC) and aesthetic components (AC) of the Index of Orthodontic Treatment Need (IOTN) were used as an assessment measure of the need for orthodontic treatment for the total sample. Results: The results indicated a high prevalence of Class I (34.9%) and Class II, Division 1 malocclusions (40.0%). Moreover, increased (18%) and reduced bites (14.%), and increased (25.1%) and reversed overjet (10.%) were present in the sample. Conclusion: Using the DHC of the IOTN, the proportion of subjects estimated to have great and very great treatment need (grades 4 and 5) was 28.%. However, only 16.7% of individuals were in need (grades 8-10) of orthodontic treatment according to the AC. © 2015 Dental Press Journal of Orthodontics.

    Prevalence of Temporomandibular Dysfunction and its Association with Malocclusion in Children: An Epidemiologic Study
    (Journal Pedodontics Inc, 2017) Bilgic, Fundagul; Gelgor, Ibrahim Erhan
    Introduction: Malocclusion is one etiological factor of temporomandibular joint disorder (TMD). This study investigates the prevalence of TMD and the relationship between TMD and the type of occlusion. Study design: A sample of 923 children (463 girls and 460 boys, ages 7-12 years old) was grouped not only by chronological age but also by gender. The information was collected on functional occlusion (anterior and lateral sliding, interferences), dental wear, mandibular mobility (maximal opening, deflection, deviation), and temporomandibular joint and muscular pain recorded by palpation. Results: Headache was the only symptom of temporomandibular dysfunction (TMD) reported by the children. The results showed that one or more clinical signs were recorded in 25% of the subjects, most of which were mild in character. The prevalence increased during the developmental stages. Girls were in general more affected than boys. Conclusions: In this study, many subjects with TMD had malocclusions. Early treatment may be important in the prevention of severe TMD. Significant associations were found between different signs, and TMD was associated with posterior crossbite, anterior open bite, Angle Class II and III malocclusions, and extreme maxillary overjet.
