ADEX Diagnostic Skills Examination (DSE) Practice Test

Managing a lateral incisor with a mid-root fracture requires careful consideration of the tooth's vitality and the extent of the fracture. Stabilizing the tooth for a period of three weeks is an appropriate approach because it allows for initial healing and assessment of the tooth's condition.

In cases of root fractures, especially if the coronal segment remains vital, stabilization through splinting can help minimize movement and provide support during the healing process. After this period, further evaluation, such as radiographs, can be performed to assess the fracture's healing and determine the need for any additional treatment, such as root canal therapy or further restorative measures.

Extraction would not be the first choice unless there is no hope for recovery or if the tooth is no longer salvageable. Immediate root canal treatment might lead to unnecessary intervention if the tooth can heal spontaneously, so it's typically reserved for cases where the tooth is symptomatic or there are signs of necrosis. Waiting for spontaneous healing might be too passive without stabilization, which could increase the risk of complications. Thus, stabilizing the tooth for three weeks is the best option to promote potential healing and preserve the tooth's function.
