Objective: To describe erupting maxillary canine positions in patients with bone-grafted alveolar clefts. Sample: The sample consisted of 101 cleft sites from patients with complete unilateral or bilateral cleft lip and palate who had early (≤9 years) or late (>9 years) secondary alveolar bone grafts. Methods: Canine position was assessed using panoramic radiographs taken before and after alveolar bone grafts. Vertical canine positions were assessed using the long axis of the maxillary permanent canine relative to a 90° vertical reference line. Lateral canine positions were defined using the relationship between the canine tip and the midplane of the lateral incisor root. Anomalous lateral incisors were recorded. Statistical analysis included Student's t tests and chi-square tests. Results: Patients with alveolar clefts had a 20-fold increased risk for canine impaction, based on erupting canine positions. Abnormal vertical canine positions decreased following early and late alveolar bone grafts ( p < .05), whereas abnormal lateral canine positions increased following late alveolar bone grafts ( p < .01). Of the cleft sites with altered canine positions, 61% also had a lateral incisor anomaly. Based on canine position, the non–cleft-side canine had the same risk for impaction as the cleft-side canine. Conclusions: Patients with alveolar clefts have a significantly higher risk for canine impaction compared with patients without clefts. Timing of alveolar bone grafts and lateral incisor anomalies influenced the risk for canine impaction. An alveolar bone graft should be planned in accordance with maxillofacial development, including the eruption of teeth adjacent to the cleft.

Aim: To investigate differences in sella turcica size and bridging in children with unilateral cleft lip and palate (UCLP) with or without concomitant dental anomalies. Patients and Methods: A cross-sectional study was carried out looking at 56 children with nonsyndromic UCLP. Lateral cephalograms, taken before alveolar bone grafting, were used to assess sella turcica height, width, area, and bridging. Panoramic radiographs were used to evaluate the presence of dental anomalies in the cleft area including agenesis, supernumerary, and peg-shaped lateral incisors. Differences between sella turcica measurements in the presence or absence of dental anomalies were assessed using t tests. Differences between the prevalence of dental anomalies and sella turcica bridging were assessed using χ2 and Fisher exact tests. Multinomial logistic regression was used to investigate potential associations between sella measurements and dental anomalies. Results: Twenty-six of the 56 children presented with agenesis of the cleft-side lateral incisor, while 7 had a supernumerary, and 19 had a peg-shaped lateral incisor. With regard to sella turcica bridging, 27 children had no calcification, 25 partial and 4 complete calcification. Children with agenesis of the cleft-side lateral incisor showed a shorter sella maximum height ( P = .010) and a smaller area ( P = .019). When looking at sella turcica bridging, 100% of children with complete calcification showed agenesis of the cleft-side lateral incisor, compared with 52% and 33% of children with partial calcification and no calcification, respectively ( P = .034). Conclusions: Children with UCLP and sella turcica bridging are more likely to present with agenesis of the cleft-side maxillary lateral incisor.

Aim: To evaluate the association of environmental risk factors, particularly paternal and maternal age, with gender and type of oral cleft in newborn with nonsyndromic cleft lip with or without cleft palate (NSCL/P). Methods: This study included 1,346 children with NSCL/P of two Brazilian Services for treatment of craniofacial deformities. Parental ages were classified into the following groups: maternal age <35, 36-39, and ≥40 years; paternal age <39 and ≥40 years. The data was analyzed with chi-square test and multinomial logistic regression analysis. The odds ratios were estimated with a 95% confidence interval. Results: Of the 1,346 children included in this study, CLP was the type of NSCL/P with highest prevalence, followed by, respectively, CL and CP. There was a greater occurrence of NSCL/P in males compared to females (55.8% versus 44.2%). CLP was more common in men, while the CL and CP were more prevalent in women (p=0.000). No association between maternal age and clefts was observed (p=0.747). However, there was evidence of association between father’s aged ≥40 years old and NSCL/P (p=0.031). When patients with CP were analyzed separately, no association between the father’s age and the child’s gender (p=0.728) was observed, i.e. the female gender prevails among patients with CP, regardless of the father’s age. Conclusions: This study showed that there were differences in the distribution of the non-syndromic cleft lip and/or palate and the gender, and fathers aged ≥40 years old may have increased risk of oral cleft. Further studies involving different populations are needed for a better understanding of the effect of maternal and paternal ages as a risk factor for the occurrence of oral clefts.

Alveolar Bone Grafting

Objective: To examine the effect of migration of the germ of the lateral incisor into the bone for eruption factors on bone bridge resorption. Methods: Twenty-five subjects who underwent secondary alveolar bone graft were enrolled. The volume of the alveolar bone grafts immediately after the operation (V1), bone bridge formation 6 months postoperatively (V2), and tooth (teeth) migration into the bone bridge (Vt) were measured using a computed tomography (CT) image analyzer. Based upon these measurements, the following points were examined: (1) the correlation between the tooth-occupied ratio (Rt = Vt/V2 × 100) and the ratio of bone bridge resorption (Rv = (V1 − V2)/ V1 × 100); and (2) comparison of the tooth-occupied ratio (Rt) and the ratio of bone bridge resorption (Rv) between the groups with and without the germ of the lateral incisor. Results: A significant negative correlation was found between Rv and Rt (p < .001). Comparison of Rv and Rt between the groups with and without a germ of the lateral incisor revealed that both indices were significantly higher in the former group than the latter one (p < .05). Conclusion: In cleft lip and palate patients with a germ of the lateral incisor, it is beneficial to carry out secondary bone grafting to the alveolar cleft at the age of 5 to 7 years, preceding eruption of the canine, in order to form a good bone bridge that will facilitate eruption of the lateral incisor and subsequent normal dentition and occlusion.

Objective: To quantify dental anomalies in permanent dentition associated with complete unilateral cleft lip and palate and to survey treatment modalities used to address these problems. Method: Retrospective study of 116 children with complete unilateral cleft lip and palate treated at SickKids since birth. Presence and morphology of lateral incisors and second premolars were determined. Orthodontic, surgical, and/or prosthetic procedures were analyzed. Results: The cleft-side lateral incisor was absent in 93.1% of finished cases. The lateral incisor mesial to the cleft was present in 4.3%, absent due to agenesis in 75.9%, and extracted in 19.8% of cases. The lateral distal to the cleft was present in 2.6%, absent due to agenesis in 33.6%, and extracted in 63.8% of cases. Of 105 lateral incisors, only one had normal morphology. Noncleft-side lateral incisors were absent in 16% of finished cases. Absence was due to agenesis in 12.1% of cases and extraction in 4.3%. When the lateral incisor was missing, closure of the dental space occurred by orthodontic tooth movement after alveolar bone grafting (45%); surgical closure with simultaneous alveolar bone grafting (35%); prosthetic closure (17%); and 3% were failures. Agenesis of premolars occurred in 12.1% of cleft-side and 10.3% of noncleft-side maxillary second premolars. Conclusions: The cleft-side lateral incisor is rarely present at the conclusion of orthodontic and surgical treatment of complete unilateral cleft lip and palate. Often absent due to agenesis, when present it is typically abnormal in size and bone support and is commonly extracted in favor of canine substitution.

Purpose. To compare the results of secondary alveolar bone grafts in patients with complete cleft lip and cleft lip and palate using 2 radiographic scales and according to the rate of canine eruption through the newly formed bone. Materials and Methods. We analyzed pre- and postoperative radiographs of 36 patients for the amount of bone in the cleft site according to the Bergland and Chelsea scales. The associations between the variables and the correlation between the scales were measured. Results. A total of 54.2% and 20.8% of cases were classified as type I and type II, respectively, using the Bergland scale, whereas 50% and 22.5% were classified as types A and C, respectively, using the Chelsea scale. A positive correlation between the 2 scales was observed. In 33.3% of males, 58.3% of females, 54.5% of unilateral cleft cases, and 12.5% of bilateral cleft cases, the permanent canines had erupted. Bone grafts performed prior to canine eruption achieved more satisfactory results. Conclusions. Our results suggest that both radiographic scales are important tools for the evaluation of bone grafts. Additionally, longer time periods of evaluation were associated with improved results for patients with secondary alveolar bone grafts.
