Studies addressing the periodontal health of the teeth surrounding the bone-grafted cleft in patients born with unilateral cleft lip and palate disagree on whether periodontal health is compromised. To determine periodontal health differences between the cleft and the non-cleft sides nearly a decade after secondary alveolar bone grafting. This prospective, controlled (split-mouth design) study comprised an intraoral apical radiographic and a periodontal examination of 40 consecutive patients from one centre (n = 26 males) who had undergone bone grafting at mean age of 10.2 years (±1.6). Probing pocket depth, gingival index, gingival recession, and radiographic bone support were assessed. No significant difference occurred in probing pocket depth between teeth at cleft and non-cleft sites (OR 1.8, P = .488). Gingival recession was present at 6.6% of all examined sites on the cleft side and at 1.7% on the non-cleft side (OR 17.3, P < .001). Gingival recession occurred most often on the buccal and disto-buccal surfaces of the central incisor on the cleft side. The gingival index was significantly higher on the cleft side (OR 8.0, P < .001). The Bergland index was I or II in most patients (87%). Recruitment of eligible patients was lengthy. 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.
