- 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.

- 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.
