Abstract

The objective of this study was to evaluate bone density changes around the teeth during orthodontic treatment by using cone beam computed tomography (CBCT). CBCT was used to measure the bone densities around six teeth (both maxilla central incisors, lateral incisors, and canines) before and after 7 months of orthodontic treatment in eight patients. In addition, each root was divided into three portions (cervical, intermediate, and apical) to determine whether the bone density change varied with tooth level. The mean reduction in bone density around the measured teeth was 24% after orthodontic treatment. The bone density reduction around teeth was largest for the upper-right and upper-left central incisor (29% and 26%, respectively) and ranged from 20% to 23% for the other four teeth. The mean bone density reduction did not differ significantly between the cervical, portion, and apical portions of the teeth (26%, 22%, and 24%, respectively). CBCT is useful for evaluating bone density changes around teeth during orthodontic treatment. The bone density around the teeth reduced significantly after the application of orthodontic forces for 7 months.

Der Aufbau von Geweben und Organen während der Embryonalentwicklung wird von den Zellen bemerkenswert choreografiert. Für diesen Prozess braucht es spezielle sogenannte „Organisatoren“. In einer aktuellen Veröffentlichung im Fachjournal Nature Cell Biology berichten Forschende durch welchen Vorgang diese Organisatoren im Gewebe entstehen und wie sie dann die Bildung von Zähnen orchestrieren.
