Occlusal Characteristics of Patients Treated in the Orthodontic Department of the Department of Odontology
Background: The objective of this study was to determine the occlusal characteristics of the patients treated in the dentofacial orthopedics department of the Department of Odontology of Dakar.
Methods: A retrospective cross-sectional descriptive study was carried out, based on the files of patients who came to the Dentofacial Orthopedics Department for consultation. Patients who had not received prior orthodontic treatment were included in this study . On each selected file, sociodemographic data as well as clinical data constituted by the reason of the consultation and the occlusion in the 3 dimensions were collected. A data entry form was set up with the epi info 7 and analyzed using the epi 2000 software. A t test on independent sample was used to compare the age-sex variable.
Results: 109 cases were selected in a total of 222 identified. The average age was 9 years ± 2.27 . 4 1% of patients were in Angle class I against 34% in class II and 1 4% in class III. Vertically , 39.81% of the patients were in normocclusion while 25% had a deep overbite and 34% an open bite. Regarding the transversal dimension, 91.7 4% of the patients had a normocclusion whereas 3% and 4% presented respectively a posterior crossbite and a scissors bite.
Conclusion: These occlusal features are different from those found in other geographical areas. The ethnicity, the age of the patients and the method of recording occlusal data may explain these disparities. It is necessary to take into account the occlusal characteristics in order to undertake an adequate interceptive treatment.
