Abstract [en]

ABSTRACT

   Cone beam computed tomography (CBCT) can be used for radiographic diagnosing of patients with bilateral cleft lip and palate. It gives a high possibility for detailed assessments of the jaws, but also ten times higher effective radiation dose than the routine intraoral radiographic examination of the area.

  The aim of this study was to compare assessments with intraoral radiographs and CBCT of the bony part of palatal clefts and adjacent teeth in adolescents with bilateral cleft lip and palate (CLP).

   Ten patients with bilateral CLP who had been examined with both CBCT and intraoral radiographs prior to surgery with bone grafting were included. Three specialists in Oral and Maxillofacial Radiology reviewed CBCT and intraoral examinations independently. They made assessments regarding teeth and cleft. Differences in results between methods and observers were assessed.

   There was no significant difference between the methods when assessing the teeth measures, except in some complicated cases where CBCT was superior to the intraoral examination. Since the radiation dose is lower for intraoral examinations that is preferable when the diagnostic results are comparable to CBCT. However, in complicated cases it might be necessary to examine the patient with CBCT to make more accurate interpretations, i.e. the examination is justified.

   A significant difference was found when assessing facial height and bucco-palatal width of the cleft, where CBCT was superior to intraoral radiography. If these measures influence treatment planning, CBCT can be justified. However, this needs to be investigated.
