- Background: The Scandcleft trial is a randomized controlled trial that includes children with unilateral cleft lip and palate where registrations are standardized and therefore provides the opportunity to describe craniofacial characteristics in a very large sample of patients. Objectives: The aim of this study was to describe craniofacial growth and morphology in a large study sample of 8-year-old children with unilateral cleft lip and palate (UCLP); before orthodontic treatment and before secondary alveolar bone grafting; and to compare the cephalometric values with age-matched non-cleft children from previous growth studies to identify the differences between untreated cleft- and non-cleft children. Materials: There are 429 eight-year-old UCLP patients in the Scandcleft study group. A total of 408 lateral cephalograms with a mean age of 8.1 years were analysed. Cephalometric analyses were performed digitally. The results from three previously published growth studies on non-cleft children were used for comparison. Results: Cephalometric analyses showed a large variation in craniofacial morphology among the UCLP group. In general, they present with significant maxillary retrusion and reduced intermaxillary relationships compared to the age-matched non-cleft children. In addition, the vertical jaw relationship was decreased, mainly due to decreased maxillary inclination. The upper and lower incisors were retroclined. It can be expected that these differences will increase in significance as the children age. Conclusion: Results from this study provide proposed norms for the young UCLP before any orthodontic treatment and can be valuable for the clinician in future treatment planning.

- Aims: To determine reliability and predictive validity of the 5-year-olds’(5YO) Index and GOSLON Yardstick in 119 patients born with unilateral cleft lip and palate at 5, 7/8, 10, 15/16, and 19 years. Methods: Five hundred thirty-four dental study models were appraised by 2 teams in 2 centers, twice in each center. Intrateam and interteam reliability in scoring the models was calculated using κ. Dental arch prediction rates were calculated as the proportion of models remaining in the same category (good–scores 1 and 2; fair–score 3; poor–scores 4 and 5) over time. Results: Intrateam and interteam κ statistics ranged from 0.74 to 0.89 and from 0.74 to 0.81, respectively. The 5YO Index and GOSLON Yardstick at 5 years produced almost identical results. The prediction rate of 19-year-old (n = 106) outcome was >80% for those in groups 1 and 2 at 5 years, while for those in groups 4 and 5 prediction was poor (<40%). Prediction of groups 4 and 5 remained poor until 10 years when it increased to 77%. At 15/16 years prediction rate was 93% for those in groups 4 and 5. Prediction of cases in group 3 was very poor at all ages. Conclusions: These results question the predictive value of “poor” dental arch relationships before 10 years of age. However, the predictive value of “good” dental arch relationship scores over time is good in all age groups. This has implications for audit policies to predict facial growth outcomes. © American Cleft Palate-Craniofacial Association. All rights reserved 2020.

- Background: It is suggested that dental agenesis affects maxillary protrusion and dental arch relationship in children with unilateral cleft lip and palate (UCLP). In addition, an association between the need for orthognathic surgery and dental agenesis is reported. Aim: The aim was to study the impact of maxillary dental agenesis on craniofacial growth and dental arch relationship in 8-year-old children with UCLP. Subjects and methods: The sample consisted of individuals with UCLP from Scandcleft randomized trials. The participants had available data from diagnosis of maxillary dental agenesis as well as cephalometric measurements (n = 399) and GOSLON assessment (n = 408) at 8 years of age. Results: A statistically significant difference was found for ANB between individuals with agenesis of two or more maxillary teeth (mean 1.52 degrees) in comparison with those with no or only one missing maxillary tooth (mean 3.30 degrees and 2.70 degrees, respectively). Mean NSL/NL was lower among individuals with agenesis of two or more maxillary teeth (mean 9.90 degrees), in comparison with individuals with no or one missing maxillary tooth (mean 11.46 degrees and 11.45 degrees, respectively). The number of individuals with GOSLON score 4-5 was 47.2% in the group with two or more missing maxillary teeth and 26.1% respectively 26.3% in the groups with no or one missing maxillary tooth. No statistically significant difference was found in the comparison between individuals with no agenesis or with agenesis solely of the cleft-side lateral. Conclusion: Maxillary dental agenesis impacts on craniofacial growth as well as dental arch relationship and should be considered in orthodontic treatment planning.
