ABSTRACT

SUMMARY:

Craniofacial symmetry is an important factor in creating a harmonious facial appearance. Genetic and external factors may cause the formation of mandibular asymmetry. The aim of this study was to evaluate vertical mandibular asymmetries in adolescents who had unilateral mandibular first permanent molar (FPM) teeth extracted at an early age. The study group consisted of 60 subjects (30 females, 30 males with a mean age of 16.18±1.04 years) who had their mandibular permanent first molar tooth extracted before the age of 12, and the control group consisted of 60 healthy subjects (30 females, 30 males with a mean age of 16.23±0.92 years). Condylar asymmetry index (CAI), ramal asymmetry index (RAI), and condylar-ramal asymmetry index (CRAI) were calculated using panoramic radiographs of the subjects. Independent samples t-test was used to evaluate the differences between groups. CAI, RAI, and CRAI values were similar between male and female subjects in both control and study groups, and no statistically significant difference was found (p>0.05). No statistically significant difference was observed between the group who had their mandibular first permanent molar teeth extracted at an early age and the control group (p>0.05). CAI values were relatively higher in both groups, but there was no significant difference between the CAI, RAI, and CRAI values between the groups.
RESUMEN
La simetría craneofacial es un factor importante para crear una apariencia facial armoniosa. Factores genéticos y externos pueden causar la formación de asimetría mandibular. El objetivo de este estudio fue evaluar las asimetrías mandibulares verticales en adolescentes a quienes se les extrajo el primer molar permanente (FPM) mandibular unilateral a una edad temprana. El grupo de estudio consistió en 60 sujetos (30 mujeres, 30 hombres con una edad media de 16,18±1,04 años) a quienes se les extrajo el primer molar mandibular permanente antes de los 12 años, y el grupo control consistió en 60 sujetos sanos (30 mujeres, 30 hombres con una edad media de 16,23±0,92 años). El índice de asimetría condilar (CAI), el índice de asimetría ramal (RAI) y el índice de asimetría condilar-ramal (CRAI) se calcularon utilizando radiografías panorámicas de los sujetos. Se utilizó la prueba t de muestras independientes para evaluar las diferencias entre los grupos. Los valores de CAI, RAI y CRAI fueron similares entre los hombres y las mujeres tanto en el grupo control como en el de estudio, y no se encontraron diferencias estadísticamente significativas (p>0.05). No se observaron diferencias estadísticamente significativas entre el grupo al que se le extrajo el primer molar permanente mandibular a una edad temprana y el grupo control (p>0,05). Los valores de CAI fueron relativamente más altos en ambos grupos, pero no hubo diferencias significativas entre los valores de CAI, RAI y CRAI entre los grupos.
