Abstract

Aim: This study evaluates the influence of premature unilateral loss of mandibular deciduous molars on condylar and ramus vertical symmetry, on digital orthopantograms of a sample of Romanian patients. Material and methods: The retrospective study was performed on 200 patients (128 boys and 72 girls), between 6-9 years old, during 2010-2015, in the Clinic of Pediatric Dentistry Ambulatory of the “Sf. Spiridon” County Clinical Emergency Hospital from Iasi, Romania. The digitally measurements were made with Planmeca Romexis Viewer 3.0.1®, according method to a known method. Results: Statistically significant differences were found between the control group (without loss of deciduous molars) and the study group (with premature unilateral loss of mandibular deciduous molars) for mean values of the condylar asymmetry index (p=0.000), which were over 5-7%, indicating the condylar asymmetry. Conclusions: The premature unilateral loss of the mandibular deciduous molars is a risk factor for the condylar symmetry.
