Abstract Objective: To determine the presence of specific patterns of dental defects in a group of individuals born with clefts. Design: Case-control. Setting: Nossa Senhora do Loreto Municipal Hospital and Federal University of Rio de Janeiro Pediatric Dentistry Clinics, Rio de Janeiro, Brazil. Patients: 642 radiographic and clinical records were evaluated, 321 cases and 321 controls. Results: Individuals born with clefts presented considerably more dental anomalies in comparison to controls (p = 0.0001). The most frequent was tooth agenesis (n = 53; p = 0.001), followed by supernumerary teeth (n = 14; p = 0.11) and tooth malposition (n = 11; p = 0.33). Regarding tooth agenesis, the upper lateral incisors were more frequently absent in the cleft group (31/86) while control individuals presented more agenesis of the mandibular second premolars (19/45). Conclusions: The higher prevalence of dental anomalies, especially number anomalies, opposite of the cleft area, in individuals born with cleft lip and/or palate is the commonest associated dental anomaly outside the cleft area. Key words: cleft lip, cleft palate, dental anomalies.
