Primary and secondary dentition anomalies were not observed in infants with CP and different in the UCL group ( P = .003). Risk differences involved primary supernumerary teeth ( P = .0001) and talon cusp formation ( P = .0001), and secondary tooth agenesis ( P = .001) of the maxillary lateral incisor on the side of the cleft lip. Delayed primary and secondary dental maturation occurred in the UCL and CP groups, greater in infants with UCL ( P &lt; .0001). Primary and secondary dental maturation featured sexual dimorphism with greater delay in males (UCL, P &lt; .0001; CP, .0001 &gt; P = .001). The effect of cleft severity on dental maturation was significant in infants with UCL ( P = .0361) and CP ( P = .0175) in the primary but not in the secondary dentition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>There were different dental anomalies in the primary and secondary dentitions in operated infants with UCL and no dental anomalies in unoperated infants with CP.
