    Abstract:
    INTRODUCTION: Cleft lip with or without cleft palate (CL/P) is congenital deformity associated with hyperdontia. OBJECTIVE: To determine the prevalence and characteristics of supernumerary teeth in patients with CL/P. DESIGN: Retrospective descriptive and correlation clinical study. PATIENTS: One hundred thirteen children with cleft (age ranged 9.3-19.2; 67 males and 46 females) treated in Clinic of Congenital Facial Deformities Medical University of Lublin were included in the study. METHODS: Records evaluation was conducted regarding age, gender, cleft type (Q36, Q37-International Classification of Diseases 10th revision), cleft side, and incidence of supernumeraries. In all supernumerary teeth, size, shape, and developmental degree were analyzed and correlation between the incidence of hyperdontia with different variables was checked. Correlations were detected using chi-square and the Yates correction. RESULTS: The majority of the examined group were males-59.29% with Q37 (67.26%) and the cleft on the left side (62.83%). Hyperdontia was noted in 26.55%. Only upper lateral incisors were affected. They usually had atypical shape (56.67%), reduced size (83.33%), and delayed development (56.67%). CONCLUSIONS: The prevalence of supernumerary permanent teeth in patients with cleft was higher than in the general population. Anomaly was more frequent in male patients and occurred mainly on the cleft side. The severity of the cleft did not influenced the frequency of supernumerary teeth, their shape, size, and developmental degree. Supernumerary teeth were characterized by reduced crown size, abnormal structure, incorrect inclination, and delayed development phase.
