Long-term radiographic and periodontal evaluations of the bone-grafted alveolar cleft region in young adults born with a UCLP.

The teeth on the cleft side had high levels of gingival inflammation. Few pathological gingival pockets, however, were found. Shallow gingival recessions frequently occurred around the central incisor on the cleft side. Teeth in the bone-grafted cleft region generally had good bone support.
