Interdental Area in the Aesthetic Zone of Maxilla ? Variations of Distance between Interdental Alveolar Crest and Interdental Contact Point in Relation with Age and Sex

CBCT- radiographic techniques, can be used to assess the morphological characteristics of the alveolar bone in the aesthetic zone of maxilla. The goal of the present study was to compare the length of distance between the contact point and the most coronal point of the interdental bone in patients of different age groups and different sexes. Th study included 406 measurements in CBCT images of 85 patients with no pathological alveolar bone loss and with visibly closed contact areas. Exclusion criteria included missing upper frontal teeth, teeth crowding, restored maxillary frontal teeth. Statistical analysis was performed using descriptive analysis of the SPSS version 19 software package. The mean ( standart deviation) distance from the interdental bone crest to the contact point between maxillary canines and lateral incisors was 3.9 0.9 mm, between lateral and central incisors was 4.2 0.9 mm, and between central incisors was 4.1 1.0 mm In patients without periodontal diseases, the length of distance between the crest of the interdental bone and the contact point of adjacent maxillary frontal teeth is not in correlation of the age and sex of the investigated individuals.
