Introduction. The most common malformations associated with cleft lip and palate are dental abnormalities. Multifactorial etiology and the time of the formation of cleft palate and start building the dental lamina may be the cause of coexistence cleft defects and dental disorders. Aim of the study. Evaluation of the frequency and type of dental disorders in patients with complete unilateral cleft of the primary and secondary have been the subject of the research. Material and methods. The material consisted of panoramic films of 70 children (31girls, 39 boys) aged 8–11 years with a complete unilateral cleft of the primary and secondary. The radiographic evaluation are: dental status, number of teeth, and their construction. Results. In the group of 70 children were found to have abnormalities in the number and morphology of the teeth in a total of 60 patients (29 girls, 31 boys). The most commonly observed disorder was hypodontia (66.4%) found in 44 patients. Missing teeth (89.8%), were mainly found in upper jaw. In 67.7% hypodontia was on the incisors side located in the vicinity of cleft. There were also lack of upper premolars (29%) and central incisors (3.3%). Hyperdontia occurred in 9.6% and concerned maxillary lateral incisors on the cleft side. Another observed disorder was atypical tooth structure (24%) on the lateral incisors in the upper jaw.
