Influence of Lateral Cephalometric Radiographs on Orthodontic Treatment Planning of Class II Patients


Stupar, Irina; Yetkiner, Enver; Wiedemeier, Daniel; Attin, Thomas; Attin, Rengin (2018). Influence of Lateral Cephalometric Radiographs on Orthodontic Treatment Planning of Class II Patients. Open Dentistry Journal, 12:296-302.

Abstract

Background Lateral Cephalometric Radiographs (LCR) are a common decision-making aid in orthodontic treatment planning and are routinely used in clinical practice. The aim of this present study was to test the null hypothesis that LCR evaluation does not alter specific components of orthodontic treatment planning in Class II patients. Materials and Methods Records of 75 patients, who had been treated at the Department of Orthodontics, Centre of Dental Medicine, University of Zurich comprised the study material. Inclusion criteria were: (1) adolescents between the age of 12-15, (2) permanent dentition with Class II buccal segment relationship (3) absence of craniofacial and dento-alveolar malformations. Fifteen orthodontists from the dental faculties of Istanbul University, Istanbul and Ege University, Izmir filled out Likert-type linear scale questionnaires without knowing that they would repeat the same procedure with and without LCRs at two different time points. Equivalence and clinical relevance were assessed using (%95 CI) Wilcoxon signed rank tests. Results Extraction decision did not differ between groups (=0.68). Preference of functional appliance use (=0.006) and inter-maxillary fixed functional appliance (p=0.043) was different among groups. Conclusion LCR evaluation has minor influence on treatment planning procedure of Class II patients. It might be beneficial to consider its prescription not in a routine manner but as a supplementary tool considering possible reduction of radiation exposure.
