Two to eight years after receiving autogenous iliac crest grafts for treatment of alveolar cleft defects, eighteen patients who had unilateral cleft palate were evaluated for their periodontal status. When cleft-associated canines were compared with contralateral control canines, no statistically significant differences were found between specific surface values for plaque index, gingival index, or probing depths. Attachment loss was found to be greater (<0.72 mm) on the mesio-facial, facial, and mesiopalatal surfaces of the cleft-associated canines than on the control canines. Fifty-six per cent of the cleft-associated canines required surgical exposure and 44% also required orthodontic assistance to erupt to a functional occlusion. Osseous grafting of alveolar cleft defects resulted in satisfactory clinical periodontal support for cleft-associated canines.
