Dental anomalies in the incisor-canine region in patients with cleft lip and palate - literature review.

Tooth disorders in the anterior region of the maxilla are very common among patients with cleft lip, alveolar bone and palate. The authors concentrate on dental disorders, erupting problems and root development, specifying dental anomalies - especially regarding the lateral incisor, central incisor and canine. Disorders may relate to the shape of the tooth, its location, size, number and they can be considered separately or together. Anomalies can be affected by many factors, such as orthodontic or surgical treatment, the presence of supernumerary teeth, lack of bone, genetic factors and many others. Each group of cleft is different and the following anomalies can be identified: UCLP (unilateral cleft lip and palate), BCLP (bilateral cleft lip and palate), UCLA (unilateral cleft lip and alveolus) and BCLA (bilateral cleft lip and alveolus). This article is intended to summarise some of the most recent knowledge about tooth disorders in the anterior region of cleft lip and palate patients and present them in an orderly way.
