Bilateral Cleft Lip

The aim of this study was to describe maxillary and mandibular dental-arch form and occlusion in bilateral cleft of the lip and palate (BCLP) from 3 to 17 years of age and to compare their characteristics with a normative sample. A sample of 22 patients with BCLP was investigated, with a noncleft control sample used for comparison. Dental-arch dimensions were studied on dental casts. A comparison between both groups was made at fixed time intervals. From 9 years of age, the cleft sample showed a significantly smaller maxillary depth. Maxillary dental-arch widths were also significantly smaller than in the control group over the whole age period. Mandibular dental-arch measurements were very similar In both groups, although smaller first-molar widths were noted in the BCLP group beginning at 12 years of age. A tendency for end-to-end occlusion was found, which became more clear with age and was most markedly in the canine region.

The purpose of the study was to localize the characteristic craniofacial abnormalities in young children with complete bilateral cleft lip and palate, to average their growth changes, and to compare all these to observations from a normative sample. A longitudinal sample of 30 males with complete bilateral cleft lip and palate was obtained from the files of the Craniofacial Center at The Hospital for Sick Children, Toronto. An age-matched noncleft control sample was selected from the Burlington Orthodontic Research Center. All individuals had lateral cephalometric radiographs at approximately 6 years, 12 years, and as adults. These were analyzed by cephalometrics and by tensor biometrics. The results of the two methods of analysis were in agreement and tended to complement each other. In the cleft sample, there was little cleftinig effect on the midline structures of the cranial base; the premaxilla was initially protruded but became normal in the adult; the nasal bone was longer and more protruded; the posterior maxillary segments were hypoplastic and the bony pharynx narrower; there was overeruption of the posterior teeth; and the mandibular gonial area was smaller.

Significant Difference

Objectives: The aim of this study is to evaluate the prevalence and distribution of hypodontia, inside and outside the cleft area, in an Italian population with a non-syndromic unilateral (UCLP) and bilateral (BCLP) cleft lip and palate on panoramic radiographs and comparing it with a control sample. Study design: Case group was ethnically uniform and consisted in 233 patients. The control group was composed of 1000 subjects. Patients included were between seven and fifteen years old. Descriptive analysis, using absolute and relative frequencies, was performed to check out the prevalence of gender distribution, hypodontia and cleft formation. Statistical analysis was conducted with Chi-squared test, Yate's correction and the Fisher's exact test. The power was set higher than 0.8 for each test. Results: 160 cleft patients (68.68%) presented at least one missing tooth, while 88 patients in the control groups presented agenesis (8.80%). A statistically significant difference was found in case and control groups for upper lateral incisors (37.34% and 48.07% in the case group against 2.50% and 2.60% in the control group), upper and lower second premolars (8.58%, 6.44%, 5.58% and 6.01% in the cleft group and 0.60%, 0.60%, 2.50% and 2.70% in the control group). Conclusion: Higher prevalence of dental agenesis in the maxillary dental arch is explained by the cleft defect. Higher prevalence of mandibular second premolars agenesis cannot be explained by the anatomical defect and suggests a multifactorial aetiology, including environmental and genetic factors, of the cleft condition.

Objective To investigate the effects of infant orthopedic treatment and lip adhesion on maxillary growth of patients with bilateral cleft lip and palate (BCLP). Design Prospective longitudinal study. Setting The present study was conducted at the Cleft Lip and Palate Center, Harapan Kita Children and Maternity Hospital, Indonesia, and the Department of Oral and Maxillofacial Surgery, Kyushu University Hospital, Japan. Subjects The study sample consisted of 53 patients with complete BCLP and 10 noncleft patients with other diseases. Patients with BCLP were divided into three groups: H (-), 11 patients treated without Hotz's plate; H (+), 24 treated with Hotz's plate; and LA-H, 18 treated with lip adhesion and Hotz's plate. Methods Serial dental casts were obtained from each BCLP child at the following four time points: first visit, labioplasty, palatoplasty, and 5 years of age. Each maxillary dental cast was scanned, and the linear and angular dimensions were measured. Results and Conclusion Lip adhesion showed a temporary negative effect. In all patients with BCLP, the surgeries affected the growth of the anterior arch width until the age of 5 years. Collapse of the premaxilla following labioplasty in the H (-) group affected the growth of dental arch length until the age of 5 years. Treatment using Hotz's plate prevented collapse of the premaxilla, and the growth of the arch length was comparable to that observed in the noncleft group.

Form Change

Objective: Quantitative descriptions of form (size and shape) changes are significant to the understanding of the development, treatment planning, and prognosis of patients born with cleft lip and palate. This study compared the results of traditional dental arch form change measurements, such as width, depth, perimeter, and area, with four numeric methods: finite element scaling analysis, macroelement method, Euclidean distance matrix analysis, and conventional least-squares and resistant-fit theta rho Procrustes analyses. Design: Using tooth cusp landmarks on maxillary study casts, form change measurements of a male with complete bilateral cleft lip and palate at ages 2, 5, and 6 years were made comparing each age to the next older. Results and Conclusions: With the exception of the 2- to 5-year resistant-fit analysis, all numeric methods: 1) provide comparable results, 2) provide more detailed descriptions than do traditional methods, and 3) provide results that correlate well with the reported effects of increased lip pressure due to lip closure surgery. The use of finite-element scaling analysis on study casts is somewhat limited since: 1) there is more than one solution at teeth shared by many finite elements, 2) gross averaging of form change occurs within triangular elements, and 3) solutions can vary with the choice of element location. The use of the macroelement method circumvented the above finite element limitations with out compromising finite-element advantages. Procrustes results vary with the chosen superposition algorithm. The choice of the most appropriate Procrustes method required some a priori knowledge of form difference. The large number of results obtained by Euclidean distance matrix analysis and the nongraphic presentation of these results hamper quick interpretation but may be best suited for definitive statistical analysis. The graphic representation of both the magnitude and direction of: 1) landmark displacement in the Procrustes analyses (once size difference is eliminated), and 2) the rate of form change in the macroelement method provide an intuitive appreciation of how and where the casts differ.

Abstract Objective: To determine whether distoangular malposition of the unerupted mandibular second premolar (MnP2) is more frequent in children with unilateral clefts of the lip and palate. Materials and Methods: This retrospective study examined panoramic radiographs from 45 patients with unilateral clefts of the lip and/or palate who had no previous orthodontics. A control sample consisted of age- and sex-matched patients. The distal angle formed between the long axis of MnP2 and the tangent to the inferior border was measured. The mean, standard deviation, and range were calculated for the angles measured in the cleft and the control groups. The significance of the differences between the means was evaluated by the paired t-test. The angles of the cleft and noncleft sides were also measured and compared. Results: The mean inclination of the MnP2 on the cleft side was 73.6°, compared with 84.6° in the control group. This difference was highly significant statistically (P < .0001). The difference in angles from the cleft and noncleft sides was 0.7°, not statistically significant. A significant association was found between clefting and distoangular malposition of the developing MnP2, suggesting a shared genetic etiology. This association is independent of the clefting side, ruling out possible local mechanical effects. Conclusion: Clinicians should be aware of the potential for anomalous development of MnP2 in children with clefts.
