DENTAL ANOMALIES IN CHILDREN WITH NON-SYNDROMIC CLEFT LIP PALATE

Objectives: To compare the frequency of dental anomalies in patients affected by Unilateral non-syndromic cleft lip palate (UNSCLP) and Bilateral non-syndromic cleft lip palate (BNSCLP) and to determine whether statistical differences are associated to cleft sides in UNSCLP.
Methods: Panoramic X-rays were analyzed from 200 children from 5 to 12 years old, 100 with non-syndromic cleft lip palate (NSCLP, 72 men and 28 women) and 100 without NSCLP (57 women and 43 men) who formed the control group. Chi square and OR were performed for statistical comparisons.
Results: 98% of the patients with NSCLP and 11% of the control group had at least one dental anomaly. In subjects with NSCLP, the most frequent anomaly was the microdontia of maxillary lateral incisors (56%), followed by agenesis (54%). There was a statistically significant difference and it was also found association in the frecuency of microdontia (p: 0.000 OR: 2,27), agenesis (p: 0.000, OR: 57,5) and supernumerary teeth (p: 0.000 OR: 10,7) by case group. Statistical significant differences were also found in the dental anomalies previously mentioned by the affected side (p<0.005).
Conclusions: The frequency of dental anomalies reported in the sample is greater than in the general population, with a higher incidence of dental anomalies in the case group and the affected side. In the present study, the NSCLP constitutes a risk factor for the presence of dental anomalies in the evaluated population.
