Cephalometric findings in patients with Papillon-Lefevre syndrome

Introduction: Literature regarding oral conditions in patients with Papillon-Lefevre syndrome (PLS) often covers the periodontal aspects, but no literature was found describing specific craniofacial findings in this group. The aim of this retrospective study was to investigate the cephalometric findings of patients with PLS. Methods: Lateral cephalograms of 8 patients with PLS were traced, and hard- and soft-tissue variables were analyzed. Results: Class III skeletal relationship was evident (ANB angle, 2 degrees +/- 3.1 degrees; Wits appraisal, -9.1 mm +/- 3.7 mm). Other findings include maxillary retrognathia, decreased lower facial height, retroclined mandibular incisors, and upper lip retrusion. Conclusions: Patients affected with PLS have a Class III skeletal pattern. These findings can be of clinical value not only for diagnosis, but also for proper treatment planning.
