Hypodontia, hyperdontia and canines impaction was recognized. From patients with CL\/P treated at the Clinic of Congenital Facial Deformities in Chair and Department of Jaw Orthopedics Medical University of Lublin, 56 subjects were randomly selected. On the panoramic radiographs taken at the age of 8\u201312 years, the angle of upper unerupted canines was measured using Westerlund\u2019s recommendations. The supernumerary teeth and hypodontia were checked. The procedures: maxillary expansion, secondary alveolar bone graft (SABG) and extraction of primary canines were noted. The frequency of canines impaction was 5.36%. Hypodontia was found in 37.5% of patients; hyperdontia was present in 23.21% of patients. No influence of procedures (expansion of the maxilla, SABG, deciduous canines extraction) on permanent maxillary canine eruption was proved. Patients with CL\/P are exposed to the unfavorable position of unerupted maxillary canines most frequently in the cleft area of complete cleft. Maxillary lateral incisor on the cleft side is most frequently affected with congenital anomaly. Hypodontia and hyperdontia do not influence maxillary canine impaction. Good clinical result was achieved with an applied approach, which should be widely introduced.<\/jats:p>","DOI":"10.3390\/jcm9123813","type":"journal-article","created":{"date-parts":[[2020,11,25]],"date-time":"2020-11-25T21:55:06Z","timestamp":1606341306000},"page":"3813","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Frequency of Additional Congenital Dental Anomalies in Children with Cleft Lip, Alveolar and Palate"],"prefix":"10.3390","volume":"9","author":[{"given":"Przemys\u0142aw","family":"Pastuszak","sequence":"first","affiliation":[{"name":"Chair and Department of Jaw Orthopedics, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Izabella","family":"Dunin-Wilczy\u0144ska","sequence":"additional","affiliation":[{"name":"Chair and Department of Jaw Orthopedics, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3654-3042","authenticated-orcid":false,"given":"Agnieszka","family":"Lasota","sequence":"additional","affiliation":[{"name":"Chair and Department of Jaw Orthopedics, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,25]]},"reference":[{"key":"ref_1","unstructured":"Materna-Kiryluk, A.
