ROOT LACERATION: RADIOGRAPHIC ANALYSIS IN PATIENTS WITH NON-SYNDROMIC LABIAL AND / OR PALATIN FISSURE

Abstract

Cleft lips and/or nonsyndromic palates (CP/NSP) represents the most common congenital abnormality in humans. Nevertheless, there are few studies that analyze the curvature and dilaceration in CP/NSP patients. The purpose of this study was to evaluate the prevalence of root dilaceration in 400 CP/NSP patients, as well as relate the root curvature degree with different kinds of clefts. It was observed that premolars and molars roots have different directions (p <0.001). Straight roots inclined to the distal face were more prevalent (46.6% and 44.5% respectively). There are differences in the location of the curvature in relation to the 1/3 root (p <0.001). The cleft lip and cleft palate had presented a higher frequency of root dilaceration. There was no significant association between the degree of root curvature of molars and premolars to a specific kind of cleft. These findings suggest to conduct a case-control study to answer questions relating to differences in angulation among CP/NSP patients with the general population.
