Objective Evaluation of the dental arch relationships of Japanese patients with unilateral cleft lip and palate (UCLP) from the orthodontic clinic of the University of Tokyo Hospital (UTH) compared with patients treated by the Oslo Cleft Team, Norway. Design Retrospective study and comparison with previous reports. Materials Dental models of 24 patients with UCLP in UTH taken before orthodontic treatment and before alveolar bone grafting were included. Surgeons in many hospitals performed primary surgeries. These models were matched for age and gender with 24 models from a consecutive series of patients treated by the Oslo Cleft Team as part of the Eurocran Good Practice Archive. A total of 48 models were evaluated. Main Outcome Measure Dental arch relationship was rated with the Goslon Yardstick. The strength of agreement of rating was assessed with weighted kappa statistics. Results Intra- and interexaminer agreements evaluated by weighted kappa statistics were high, indicating good reproducibility. Almost 60% of the patients in UTH were classified into poor or very poor categories, and the mean Goslon score was 3.50. These results show a contrast to those in Oslo and were the poorest in comparison with previous reports. Conclusion Dental arch relationships in patients with UCLP in UTH were poor. This seemed to be attributable to surgical procedures, but a factor of racial difference in the craniofacial morphology was also considered. Further intercenter research is required to clarify this point.

Objective: To compare the dental arch relationship following one-stage repair of unilateral cleft lip and palate (UCLP) in Warsaw with a matched sample of patients treated by the Oslo Cleft Team. Material: Study models of 61 children (mean age, 11.2; SD, 1.7) with a nonsyndromic complete UCLP consecutively treated with one-stage closure of the cleft at 9.2 months (range, 6.0 to 15.8 months; SD, 2.0) by the Warsaw Cleft Team at the Institute of Mother and Child, Poland, were compared with a sample drawn from a consecutive series of patients with UCLP treated by the Oslo Cleft Team and matched for age, gender, and soft tissue band. Methods: The study models were given random numbers to blind their origin. Four examiners rated the dental arch relationship using the GOSLON Yardstick. The strength of agreement of rating was assessed with weighted Kappa statistics. An independent t-test was carried out to compare the GOSLON scores between Warsaw and Oslo samples, and Fisher's exact tests were performed to evaluate the difference of distribution of the GOSLON scores. Results: The intrarater and interrater agreements were high (K ≥ .800). No difference in dental arch relationship between Warsaw and Oslo groups was found (mean GOSLON score  =  2.68 and 2.65 for Warsaw and Oslo samples, respectively). The distribution of the GOSLON grades was similar in both groups. Conclusions: The dental arch relationship following one-stage repair (Warsaw protocol) was comparable with the outcome of the Oslo Cleft Team's protocol.

Objective: To evaluate the dental arch relationships for a consecutive series from Goteborg, Sweden, who had delayed hard palate closure. Design: Retrospective study. Setting: Sahlgrenska University Hospital, Goteborg, Sweden. Patients: The dental study models of 104 consecutive unilateral cleft lip and palate subjects. The study cohort was born between 1979 and 1994. Longitudinal records were available at ages 5 (n = 94), 10 (n = 97), 16 (n = 59), and 19 years (n = 46). Five assessors rated models according to the GOSLON Yardstick on two separate occasions each. Interventions: These patients had been operated upon according to the Goteborg protocol of delayed hard palate closure (at age 8 years). Results: 85% of subjects were rated in groups 1 and 2 (excellent or very good outcome), 12% were rated in group 3 (satisfactory), and 3% were assigned to group 4 (poor). No patients presented in Group 5 (very poor). Weighted kappa statistics for double determination of Yardstick allocation for five assessors demonstrated values between .65 and .90 for interrater agreement (good/very good) and between .70 and .90 for intrarater agreement (very good). Conclusions: Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.

ABSTRACT Objective: To compare the mixed dentition incisor and molar overjet, severity of contraction of the dental arch, and the sagittal molar relationship on the cleft side vs the noncleft side in children with repaired complete unilateral cleft of the lip and palate (UCLP). Materials and Methods: Orthodontic records taken prior to orthodontic preparation for alveolar bone grafting were screened to select study casts from patients with nonsyndromic repaired complete UCLP who did not have mandibular skeletal or dental asymmetry. The study sample comprised dental casts from 74 children aged 8.9 ± 1 years. Standardized digital photographs were acquired at 1:1 magnification. A coordinate system was developed using digital image-processing software (Photoshop CS4 and Adobe Illustrator). Incisor and molar overjet, Angle's classification, and arch contraction were recorded. Descriptive statistics, paired t-tests, and kappa statistics were used to compare the cleft and noncleft sides. Results: A negative overjet of −1 to −5 mm was often present at the incisors, with greater frequency and magnitude on the cleft side. Class II molar relation was more frequent on the cleft side (61.1%) than on the noncleft side (47.2%). Significantly greater contraction of the cleft side deciduous canine and deciduous first molar was noted, while the difference was very minor at the first permanent molar. Conclusions: Cleft side maxillary arch contraction was most severe in the deciduous canine and first deciduous molar region and progressively less severe in the posterior region of the arch. A greater frequency and severity of negative overjet and Class II molar relationship was seen on the cleft side.

Objective: To determine the treatment outcome based on dentoalveolar relationships among Malay children born with nonsyndromic complete unilateral cleft lip and palate (UCLP). Design: Retrospective cohort study. Setting and Sample Population: The Department of Orthodontics at the School of Dental Science and the Reconstructive Sciences Unit, School of Medical Science, Universiti Sains Malaysia. Dental study models of 82 UCLP Malay children aged 8 to 10 years were evaluated. All subjects had their cleft lip and palate repaired, but no alveolar bone graft or any orthodontic treatment was performed. Outcome Measure: The outcome of dental arch relationships was assessed using the Goslon Yardstick Index: a dental measure with outcomes ranked on a scale ranging from 1 to 5. Agreement of rating was assessed with weighted kappa statistics; both intraexaminer and interexaminer agreements were high, indicating good reproducibility. Results: A total of 2.4% of the sample was in grade 1, 24.4% in grade 2, 35.4% in grade 3, 31.7% in grade 4, and 6.1% in grade 5. The mean Goslon index score was 3.15. Conclusion: Dentoalveolar relationship outcomes of UCLP Malay children are intermediate according to the Goslon Yardstick. Interpretation of results should consider the ethnic differences in the craniofacial complex.

Objective The objective of this study was to evaluate the craniofacial morphology of children with unilateral cleft lip and palate (UCLP) resulting from differing management protocols practiced in Prague from 1945 to 1976. Design The craniofacial morphologies of four groups of patients were compared. Two groups were assessed retrospectively (individuals born from 1945 to 1963), and two groups were followed on a longitudinal basis (individuals born from 1966 to 1976). Setting The study was conducted at the Cleft Lip and Palate Center at the Department of Plastic Surgery, Prague, which has a catchment area population of 6 million. Patients The subjects were a consecutive series of adult males (n = 84) who had complete UCLP without associated malformations. Interventions Patients born from 1945 to 1955 did not receive centralized orthodontic therapy. From 1945 to 1965, the alveolar process in the area of the cleft was not surgically repaired. Primary bone grafting was used for the group born from 1965 to 1972, and primary periosteoplasty was used in the subsequent period. Throughout the period covered by the study, the palate was operated on by pushback and pharyngeal flap surgery. From 1945 to 1965, the lip was repaired initially according to Veau, and later according to Tennison and Randall, and during this time, fixed appliances were used for orthodontic treatment. Results The results for the period from 1945 to 1955 are characterized by mandibular overclosure with anterior crossbite. Centralized orthodontic treatment in the later period improved sagittal jaw relations due to the posterior displacement of the mandible and an edge-to-edge bite was attained, but maxillary retrusion was unchanged. Primary bone grafting increased retrusion of the maxilla, which was compensated by further posterior displacement of the mandible. An edge-to-edge bite was also obtained. Primary periosteoplasty reduced maxillary retrusion, and the marked proclination of the upper dentoalveolar component with fixed appliances resulted in a positive overjet. It was no longer necessary to push the mandible back to the extent required in bone grafting. Conclusion Effective orthodontic treatment made the greatest contribution to improved facial development. It allowed compensation of maxillary retrusion by changes in the position of the mandible or by proclination of the upper dentoal-veolar component with fixed appliances. The applied surgical methods using primary bone grafting caused deterioration of the anterior growth of the maxilla.

Objective: To evaluate midfacial growth in prepubertal children with complete unilateral cleft lip and palate following one-stage simultaneous repair. Subjects: A series of 28 consecutively treated subjects with complete unilateral cleft lip and palate were compared with age- and gender-matched controls with normal midfacial structure. Methods: On the lateral cephalograms taken at the age of approximately 10 years, size and position of the maxilla and upper dental arch were evaluated in vertical and horizontal planes. Statistical analysis included independent t tests and nonparametric Mann-Whitney tests. Results: The maxilla was found to be retruded (sella-nasion-point A angle decreased by 4.5° and nasion to point A distance increased by 4.2 mm) and rotated posteriorly (sella-nasion/palatal plane angle decreased by 4.5°) in the cleft group. Maxillary length (pterygomaxillare-point A distance) was diminished by approximately 2 mm. Upper incisors were found retroclined in comparison to controls (both upper incisor axis/sella-nasion and upper incisor axis/palatal plane angles were decreased by 10.7° and 6.1°, respectively). Conclusion: Maxillary prominence, as measured with the sella-nasion-point A angle and the condylion-point A and articulare-point A distances, was decreased. Shortened length and posterior position of the maxillary body were responsible at a ratio of 60% to 40% for a decreased prominence of the maxillary complex. The palatal plane demonstrated a larger inclination to the sella-nasion plane by 4.5° due to a decreased sella-posterior nasal spine distance.

Objective: To evaluate dental arch relationship in treated bilateral cleft lip and palate (BCLP) cases at an Indian cleft center using the Bauru yardstick. Patients and methods: Digital photographs of the dental cast of 50 consecutively treated patients (28 males and 22 females) with nonsyndromic BCLP at an Indian cleft center were rated by 2 examiners as per the Bauru yardstick for the 12-year-old age group. The average age group was 12 ± 0.62 years. All cases were treated with same surgical protocol. Results: The inter-examiner agreement between the 3 examiners was found to be very high, with weighted kappa values ranging from 0.894 to 0.951. The intraexaminer agreement between the 2 examinations for all the examiners was also found to be very high, with weighted kappa values ranging from 0.894 to 0.931. Seventy-eight percent of patients were rated with a Bauru yardstick score of 1+2. In addition, 10% of patients were rated with a score of 3, 8% as 4, and 4% as 5. The overall Bauru yardstick score for the center was 2.36. Conclusion: The protocol followed for the repair of BCLP cases by the center was found to be a good regimen in regard to the Bauru yardstick score.

Summary 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. Trial registration ISRCTN29932826.
