# A child is brought to the clinic with complaint of irregular teeth. The maxillary central incisor is rotated in an otherwise normal occlusion. What should the next step be?
a) Check for supernumerary teeth
b) Resection of supracrestal fibers
c) Exert a couple on tooth
d) Fixed orthodontic appliances given
The correct answer is a. Check for supernumerary teeth.
Unerupted mesiodens and the presence of thick labial frenum between the central incisors are common causes of midline diastema.
Before attempting to close midline diastema, radiographs should be taken to rule out supernumerary teeth as the cause of diastema.
