RESUMEN
OBJECTIVE: To investigate the craniofacial growth outcomes of early secondary alveolar bone grafting(ABG) around 6 years of age. DESIGN: Retrospective cohort study. SETTING: 1 North-American and 5 Northern-European cleft centers. SUBJECTS: 33 subjects with CUCLP consecutively treated with secondary ABG around 6 years of age were compared to 105 subjects from 4 centers treated with late secondary ABG and 19 subjects from 1 center with primary ABG. METHODS: Preorthodontic standardized lateral cephalometric radiographs taken after 12 years of age were traced and analyzed according to the Eurocleft Study protocol. Fourteen angular and two proportional measurements were performed. Measurement means from the Study Center(SC) were compared to 5 Northern-European centers using analysis of variance and Welch's modified t-tests, and P < .05 was considered statistically significant. RESULTS: For the SC, the mean age ± SD at the time of bone graft was 5.85 ± 0.71 years and the mean age at the time of the lateral cephalogram was 13.4 ± 1.8 years. The sagittal maxillary prominence of the SC was favorably comparable to the 5 Northern-European centers. The mean SNA (78.1 ± 4.3) for the SC was significantly higher compared to 4 of the 5 Northern-European centers(all P < .05), and the mean ANB angle was comparable to 4 of the 5 centers. Similarly, the mean soft tissue ANB angle was not significantly different to the 5 centers. The soft tissue vertical proportions compared favorably to all 5 Northern-European centers(all P < .01). CONCLUSIONS: Craniofacial growth outcomes of early secondary ABG around 6 years compare favorably to the outcomes of late secondary ABG.

OBJECTIVE: To compare the outcomes between 2 groups of patients with complete clefts treated with early secondary alveolar bone grafting (ABG) at 2 centers (5-7 years, before orthodontic intervention) and to a third group of patients treated at one of those centers (center 1) who had received later secondary ABG (8-10 years, after orthodontic intervention). DESIGN: Blind retrospective analysis of cleft site radiographs using Americleft Standardized Way to Assess Grafts (SWAG) scale. PATIENTS: A total of 99 patients with complete clefts from 2 North American cleft/craniofacial centers. INTERVENTIONS: Secondary ABG representing 2 protocols: early grafting at a mean age of 6.6 years prior to any orthodontic intervention, and later grafting at a mean age of 10.2 years following pregrafting orthodontic intervention. MAIN OUTCOME MEASURES: Using occlusal radiographs, the SWAG scale from 0 (failed graft) to 6 (ideal) was used. Six trained, calibrated raters scored each radiograph twice, with the average of the 2 ratings used as the final score. Reliability was assessed using the weighted κ statistic. The significance of differences between groups was determined using the Kruskal-Wallis test and Dunn test for pairwise comparisons. RESULTS: Inter-rater reliability of SWAG method was good (0.631). Intra-rater reliability was excellent (0.817). There was a tendency for improved total graft outcome in the early grafted group from center 1 compared to the later grafted group with improvement being significantly different in only the coronal third of the early, preorthodontic grafted group. However, the difference was not statistically significant for the graft overall.

OBJECTIVES: 1. To evaluate the orthodontic burden of care of nasoalveolar molding (NAM) and modified McNeil for the treatment of patients with complete unilateral cleft lip and palate (CUCLP). 2. To compare the esthetic outcomes of each with those of centers not utilizing infant orthopedics (IO). DESIGN: Retrospective cohort study. SETTING: Institutional. PARTICIPANTS: Four cohorts with repaired CUCLP (n = 149) from 3 centers. INTERVENTIONS: Two cohorts were treated in the same center and had either traditional infant orthopedics (TIO) or NAM and 2 were treated in centers not employing IO. MAIN OUTCOME MEASURES: Burden of care data for the IO groups were compared using t tests. Frontal and profile photographs at approximately age 5 were collected for ratings of nasolabial esthetics, using a modification of the Asher-McDade method. Intrarater and interrater reliabilities were determined using weighted κ statistics. Median ratings were compared using a Kruskal-Wallis test. RESULTS: The burden of care of NAM was significantly greater than TIO for both the number of visits (9.9 vs 6.6, [ P < .001]); and treatment duration (127 vs 112 days, [ P < .05]). Significant differences in nasolabial esthetic ratings were noted among the 3 centers. No significant differences were observed in the nasolabial esthetic outcomes between the NAM and TIO groups. CONCLUSIONS: 1. NAM required more visits and longer overall duration compared with TIO. 2. The center employing IO showed favorable nasolabial esthetics compared to those not utilizing IO. 3. No significant differences were found in the nasolabial esthetics of patients who have received NAM compared with TIO.

The purpose of this study was to investigate ways to improve rater reliability and satisfaction in nasolabial esthetic evaluations of patients with complete unilateral cleft lip and palate (UCLP), by modifying the Asher-McDade method with use of Q-sort methodology. Blinded ratings of cropped photographs of one hundred forty-nine 5- to 7-year-old consecutively treated patients with complete UCLP from 4 different centers were used in a rating of frontal and profile nasolabial esthetic outcomes by 6 judges involved in the Americleft Project's intercenter outcome comparisons. Four judges rated in previous studies using the original Asher-McDade approach. For the Q-sort modification, rather than projection of images, each judge had cards with frontal and profile photographs of each patient and rated them on a scale of 1 to 5 for vermillion border, nasolabial frontal, and profile, using the Q-sort method with placement of cards into categories 1 to 5. Inter- and intrarater reliabilities were calculated using the Weighted Kappa (95% confidence interval). For 4 raters, the reliabilities were compared with those in previous studies. There was no significant improvement in inter-rater reliabilities using the new method. Intrarater reliability consistently improved. All raters preferred the Q-sort method with rating cards rather than a PowerPoint of photos, which improved internal consistency in rating compared to previous studies using the original Asher-McDade method. All raters preferred this method because of the ability to continuously compare photos and adjust relative ratings between patients.

BACKGROUND: Nonsyndromic cleft lip with or without cleft palate (nsCL±P) and nonsyndromic cleft palate (nsCP) are caused by a combination of genetic and environmental risk factors. We investigated gene-environment and gene-gene joint effects in a large multicenter study of case-parent triads. METHODS: The nsCL±P or nsCP triads were recruited in 11 European countries between 2001 and 2005. We collected DNA samples from infants and from their mothers and fathers, and mothers completed a questionnaire on exposures, including smoking and folic acid supplement use during pregnancy. We used log-linear regression to estimate relative risks (RRs) and 95% confidence intervals (CIs) for associations between nsCL±P or nsCP and variants in MTHFR, MTHFD1, TGFA, SATB2, and MSX1, stratifying by environmental or genetic factors. RESULTS: We obtained genotype and exposure data for 728 nsCL±P triads and 292 nsCP triads. In male infants, there was no association between the mother's homozygous MSX1 p(CA) *4/*4 genotype and nsCL±P (RR, 0.98; 95% CI, 0.63-1.54), but this maternal genotype resulted in a doubling of risk for female infants (RR, 2.21; 95% CI, 1.13-4.34). There was evidence suggestive of gene-gene joint-effects between MTHFR-TGFA for nsCP but not for nsCL±P. CONCLUSION: Although we chose the genes and their variants and putative joint effects based on associations previously reported in the literature, we replicated few associations. These results do not provide evidence supporting associations between these genes and oral clefts in European populations, although gene-environment and gene-gene interactions could play a role in oral cleft etiology.

OBJECTIVE: To compare the dental arch relationships of Turkish patients with complete unilateral cleft lip and palate (UCLP) with the results reported for participants in the Eurocleft study. PATIENTS: Study models of 109 patients with complete UCLP from five university clinics in Turkey were evaluated (clinic A = 25 patients, clinic B = 23 patients, clinic C = 20 patients, clinic D = 21 patients, and clinic E = 20 patients). The mean age of the patient cohort was nine years old (range = 8-11 years old), and the cohort was born between 1976 and 1990. METHODS: The examiners rated the three-dimensional (3D) models using the GOSLON Yardstick. The scores were compared with those from the Eurocleft centers: E1(B), E2(E), E3(A), E4(F), E5(C), and E6(D). Intra- and interexaminer agreements were evaluated using weighted kappa statistics. RESULTS: The mean GOSLON scores for the Turkish clinics were as follows: clinic A = 3.16, clinic B = 3.13, clinic C = 3.25, clinic D = 3.67, and clinic E = 3.70. Scores for three of the Turkish clinics (A, B, and C) were significantly worse than the scores for the three best Eurocleft centers, E1(B), E2(E), and E3(A) (P < .001, P < .001, and P < .05, respectively). Scores for two of the Turkish clinics (D and E) were similar to those for Eurocleft center E6(D) but worse than the scores for the other Eurocleft centers (P < .01, P < .001, respectively). CONCLUSIONS: This was the first study in which three-dimensional models were used to derive scores to compare with those of the Eurocleft centers. According to the results of analysis of 109 3D models, 50.4 % of the patients in Turkey were classified as GOSLON score 4 and 5. This may have been attributable to poor surgical procedures, low-volume surgeons, and the decentralized treatment approach in Turkey between 1985 and 2000. Further research is needed to assess the situation in Turkey in more recent years.

BACKGROUND: Cleft lip and cleft palate are common birth defects, affecting about one baby of every 700 born. Feeding these babies is an immediate concern and there is evidence of delay in growth of children with a cleft as compared to those without clefting. In an effort to combat reduced weight for height, a variety of advice and devices are recommended to aid feeding of babies with clefts. OBJECTIVES: This review aims to assess the effects of these feeding interventions in babies with cleft lip and/or palate on growth, development and parental satisfaction. SEARCH STRATEGY: The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 27 October 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 4), MEDLINE via OVID (1950 to 27 October 2010), EMBASE via OVID (1980 to 27 October 2010), PsycINFO via OVID (1950 to 27 October 2010) and CINAHL via EBSCO (1980 to 27 October 2010). Attempts were made to identify both unpublished and ongoing studies. There was no restriction with regard to language of publication. SELECTION CRITERIA: Studies were included if they were randomised controlled trials (RCTs) of feeding interventions for babies born with cleft lip, cleft palate or cleft lip and palate up to the age of 6 months (from term). DATA COLLECTION AND ANALYSIS: Studies were assessed for relevance independently and in duplicate. All studies meeting the inclusion criteria were data extracted and assessed for validity independently by each member of the review team. Authors were contacted for clarification or missing information whenever possible. MAIN RESULTS: Five RCTs with a total of 292 babies, were included in the review. Comparisons made within the RCTs were squeezable versus rigid feeding bottles (two studies), breastfeeding versus spoon-feeding (one study) and maxillary plate versus no plate (two studies). No statistically significant differences were shown for any of the primary outcomes when comparing bottle types, although squeezable bottles were less likely to require modification. No difference was shown for infants fitted with a maxillary plate compared to no plate. However, there was some evidence of an effect on weight at 6 weeks post-surgery in favour of breastfeeding when compared to spoon-feeding (mean difference 0.47; 95% confidence interval 0.20 to 0.74). AUTHORS' CONCLUSIONS: Squeezable bottles appear easier to use than rigid feeding bottles for babies born with clefts of the lip and/or palate, however, there is no evidence of a difference in growth outcomes between the bottle types. There is weak evidence that breastfeeding is better than spoon-feeding following surgery for cleft. There was no evidence to suggest that maxillary plates assist growth in babies with clefts of the palate. No evidence was found to assess the use of any types of maternal advice and/or support for these babies.

OBJECTIVE: To develop yardsticks for assessment of dental arch relationship in young individuals with repaired complete bilateral cleft lip and palate appropriate to different stages of dental development. PARTICIPANTS: Eleven cleft team orthodontists from five countries worked on the projects for 4 days. A total of 776 sets of standardized plaster models from 411 patients with operated complete bilateral cleft lip and palate were available for the exercise. STATISTICS: The interexaminer reliability was calculated using weighted kappa statistics. RESULTS: The interrater weighted kappa scores were between .74 and .92, which is in the "good" to "very good" categories. CONCLUSIONS: Three bilateral cleft lip and palate yardsticks for different developmental stages of the dentition were made: one for the deciduous dentition (6-year-olds' yardstick), one for early mixed dentition (9-year-olds' yardstick), and one for early permanent dentition (12-year-olds' yardstick).

Clefts of the lip and palate are generally divided into two groups, isolated cleft palate and cleft lip with or without cleft palate, representing a heterogeneous group of disorders affecting the lips and oral cavity. These defects arise in about 1.7 per 1000 liveborn babies, with ethnic and geographic variation. Effects on speech, hearing, appearance, and psychology can lead to longlasting adverse outcomes for health and social integration. Typically, children with these disorders need multidisciplinary care from birth to adulthood and have higher morbidity and mortality throughout life than do unaffected individuals. This Seminar describes embryological developmental processes, epidemiology, known environmental and genetic risk factors, and their interaction. Although access to care has increased in recent years, especially in developing countries, quality of care still varies substantially. Prevention is the ultimate objective for clefts of the lip and palate, and a prerequisite of this aim is to elucidate causes of the disorders. Technological advances and international collaborations have yielded some successes.

BACKGROUND: Powered brushes were first introduced commercially in the 1960s. A recent systematic review suggested the superiority of certain modes of powered over manual toothbrushing for plaque and gingivitis reduction. That review did not allow for direct comparison between different modes of powered toothbrush. OBJECTIVES: To compare different modes of powered toothbrushing against each other for plaque reduction and the health of the gingivae. Other factors to be assessed were calculus and stain removal, cost, dependability and adverse effects. SEARCH STRATEGY: The following databases were searched: Cochrane Oral Health Group's Trials Register (to 26 July 2010); Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3); MEDLINE via OVID (1950 to 26 July 2010); EMBASE via OVID (1980 to 26 July 2010); CINAHL via EBSCO (1982 to 26 July 2010). There were no language restrictions. SELECTION CRITERIA: Trials were considered for inclusion with the following criteria: random allocation of participants; no compromised manual dexterity; unsupervised powered toothbrushing for at least 4 weeks. The primary outcomes were the plaque and gingivitis scores after powered toothbrush use during trial period. DATA COLLECTION AND ANALYSIS: Data extraction was performed independently and in duplicate. The authors of trials were contacted to provide missing data where possible. The effect measure for each meta-analysis was the standardised mean difference (SMD) with 95% confidence intervals (CI) using the random-effects model. Potential sources of heterogeneity were assessed. MAIN RESULTS: The review included data from 15 trials with 1015 participants. Due to the dearth of trials assessing the same mode of action, no definitive conclusions can be stated regarding the superiority of one mode of powered toothbrush over any other. Only minor and transient side effects were reported. Cost, dependability were not reported. AUTHORS' CONCLUSIONS: Further trials of good quality are required to establish if any mode of action has superiority over the other modes of action for powered toothbrushes.

OBJECTIVE: To compare and evaluate longitudinally the dental arch relationships from 4.5 to 13.5 years of age with the Bauru-BCLP Yardstick in a large sample of patients with bilateral cleft lip and palate (BCLP). DESIGN: Retrospective longitudinal intercenter outcome study. PATIENTS: Dental casts of 204 consecutive patients with complete BCLP were evaluated at 6, 9, and 12 years of age. All models were identified only by random identification numbers. SETTING: Three cleft palate centers with different treatment protocols. MAIN OUTCOME MEASURES: Dental arch relationships were categorized with the Bauru-BCLP yardstick. Increments for each interval (from 6 to 9 years, 6 to 12 years, and 9 to 12 years) were analyzed by logistic and linear regression models. RESULTS: There were no significant differences in outcome measures between the centers at age 12 or at age 9. At age 6, center B showed significantly better results (p=.027), but this difference diminished as the yardstick score for this group increased over time (linear regression analysis), the difference with the reference category (center C, boys) for the intervals 6 to 12 and 9 to 12 years being 10.4% (p=.041) and 12.9% (p=.009), respectively. CONCLUSIONS: Despite different treatment protocols, dental arch relationships in the three centers were comparable in final scores at age 9 and 12 years. Delaying hard palate closure and employing infant orthopedics did not appear to be advantageous in the long run. Premaxillary osteotomy employed in center B appeared to be associated with less favorable development of the dental arch relationship between 9 and 12 years.

A popular method for nasolabial rating in unilateral cleft lip and palate (UCLP) is the Asher-McDade system consisting of a 5-point ordinal scale assessing nasal form, nasal symmetry, nasal profile, and vermilion border. The aim of the current study was to identify reference photographs illustrating this scale to facilitate its use.Four observers assessed nasolabial appearance on frontal and profile photographs of the nasolabial area of 42 children of Caucasian origin with a repaired UCLP at age 9 years. Cronbachs alpha, based on the individual scores of the 4 observers, ranged from 0.73 to 0.82 for the 4 nasolabial ratings, indicating a good reliability. The reliability of the overall score (mean of the 4 component scores) was also high (Cronbachs alpha, 0.83). Both for the nasolabial component ratings and for the overall score, duplicate measurement errors were small. The reliability for the mean of the 4 observers' scores was good, Spearman rank correlation coefficients ranging from 0.56 to 0.96.Subsequently, photographs were selected that showed the highest agreement among observers. For each of the 4 components (eg, nasal form, nasal deviation, nasal profile, and shape of the vermilion border), 5 photographs were selected to illustrate the whole range of the scale (score, 1-5), resulting in the selection of 20 pictures.It was concluded that nasolabial appearance rating can be performed reliably using a panel of judges and averaging the scores of all observers. Reference photographs, as developed from this study, may facilitate the rating task.

INTRODUCTION: Temporomandibular disorder (TMD) is a common condition. Studies of TMD in relation to orthodontic treatment did not show an association, but longitudinal studies from adolescence to adulthood are lacking. The aim of this study was to investigate the relationship between orthodontic treatment and TMD with a longitudinal study design. METHODS: This prospective cohort study was conducted in South Wales, United Kingdom. The baseline investigation was carried out in 1981 and involved children aged 11 to 12 years (n = 1018). Follow-up investigations were done in 1984 (n = 792), 1989 (n = 456), and 2000 (n = 337). RESULTS: Overall TMD prevalence increased from the baseline (3.2%) to age 19 to 20 (17.6%) and decreased by age 30 to 31 (9.9%). TMD prevalence was higher in females at all follow-up points, except the baseline. Overall, incidences of TMD were 11.9%, 11.5%, and 6.0% at the first, second, and last follow-ups, respectively. Females were more likely to develop TMD than males (hazard ratio [HR], 2.1; 95% CI, 1.3 and 3.3), and those with high self-esteem were less likely to develop TMD (HR, 0.6; 95% CI, 0.4 and 0.8). There was no association between orthodontic treatment and new TMD onset. The incidences of persistent TMD were 20.0%, 34.9%, and 28.0% at the first, second, and last follow-ups, respectively. Females were more likely to have persistent TMD than males (HR, 2.5; 95% CI, 1.0 and 6.1). There was no association between orthodontic treatment and persistent TMD. The only significant predictors of TMD in adults aged 30 to 31 were female sex (odd ratio, 3.0; 95% CI, 1.1 and 8.2) and TMD in adolescence (odds ratio, 4.5; 95% CI, 2.0 and 10.0). CONCLUSIONS: Orthodontic treatment neither causes nor prevents TMD. Female sex and TMD in adolescence were the only predictors of TMD in young adulthood.

OBJECTIVES: Despite the widespread belief that orthodontics improves psychological well-being and self-esteem, there is little objective evidence to support this (Kenealy et al., 1989a; Shaw, O'Brien, Richmond, & Brook, 1991). A 20 year follow-up study compared the dental and psychosocial status of individuals who received, or did not receive, orthodontics as teenagers. DESIGN: A prospective longitudinal cohort design with four studies of the effect of orthodontic treatment. Secondary analysis of outcome data incorporated orthodontic need at baseline and treatment received in a 2 x 2 factorial design. METHODS: A multidisciplinary research programme studied a cohort of 1,018, 11-12 year old participants in 1981. Extensive assessment of dental health and psychosocial well-being was conducted; facial and dental photographs and plaster casts of dentition were obtained and rated for attractiveness and pre-treatment need. No recommendations about orthodontic treatment were made, and an observational approach was adopted. At the third follow-up 337 (30-31 year olds) were re-examined in 2001. RESULTS: Participants with a prior need for orthodontic treatment as children who obtained treatment demonstrated better tooth alignment and satisfaction. However when self-esteem at baseline was controlled for, orthodontics had little positive impact on psychological health and quality of life in adulthood. Lack of orthodontic treatment where there was a prior need did not lead to psychological difficulties in later life. Dental status alone was a weak predictor of self-esteem at outcome explaining 8% of the variance. Self-esteem in adulthood was more strongly predicted (65% of the variance) by psychological variables at outcome: perception of quality of life, life satisfaction, self-efficacy, depression, social anxiety, emotional health, and by self-perception of attractiveness. CONCLUSIONS: Longitudinal analysis revealed that the observed effect of orthodontic treatment on self esteem at outcome was accounted for by self esteem at baseline. Prior need for treatment assessed in childhood made a small contribution to the prediction of self-esteem 20 years later in adulthood. Dental status in adulthood, whilst statistically significant, appeared to be of minor importance in a model that included other psychological variables. When prior need for treatment was taken into account there was little objective evidence to support the assumption that orthodontics improves long-term psychological health.

OBJECTIVE: To evaluate nasolabial appearance of patients with UCLAP treated in Nijmegen and to compare them with those from six other individual centers from the Eurocleft study. Relationships between nasolabial aesthetics, dental arch relationships and cleft width at birth were also investigated. PATIENTS: Children of Caucasian origin with complete UCLAP (n=42 consecutive cases) from the Nijmegen Cleft Palate Unit, The Netherlands. METHODS: Nasolabial appearance was assessed by applying an aesthetic index and subsequently compared with the six-centre Eurocleft study. Cleft width at birth was measured on maxillary plaster casts. RESULTS: The 90% central range for the overall aesthetic rating of the 42 Nijmegen patients is 2.0-3.7 on a scale from 1 to 5 (1=very good nasolabial appearance, 5=very poor nasolabial appearance). With regard to the overall aesthetic rating, Nijmegen showed similar treatment outcomes with Eurocleft centres A, D, E and F. Nijmegen scored significantly better than Eurocleft centre C and significantly worse than Eurocleft centre B (pAsunto(s)

RESUMEN
INTRODUCTION: Despite the widespread expectation that orthodontic treatment improves psychological well-being and self-esteem, there is little objective evidence to support this. The aim of this study was to compare the dental and psychosocial status of people who received, or did not receive, orthodontic treatment as teenagers. METHODS: A prospective longitudinal cohort design was adopted. A multidisciplinary research team evaluated 1018 participants, aged 11 to 12 years, in 1981. Extensive assessments of dental health and psychosocial well-being were conducted; facial and dental photographs and plaster casts of dentition were obtained and rated for attractiveness and pretreatment need. No recommendations about orthodontic treatment were made, and an observational approach was adopted. At the third follow-up, 337 subjects (30-31 years old) were reexamined in 2001. One-way ANOVA was used to explore differences between the 4 groups (need/no need; treatment/no treatment). RESULTS: The percentage changes in index of complexity, outcome and need scores for the 4 groups were need/no treatment (12.7%), no need/no treatment (-17.1%), need/treatment (31%), and no need/treatment (-11.4%). Participants with a prior need for orthodontic treatment as children who obtained treatment had better tooth alignment and satisfaction. However, when self-esteem at baseline was controlled for, orthodontic treatment had little positive impact on psychological health and quality of life in adulthood. CONCLUSIONS: Lack of orthodontic treatment when there was need did not lead to psychological difficulties in later life.

BACKGROUND: The burden of care for children with cleft lip and palate extends beyond primary repair. Children may undergo multiple secondary surgeries to improve appearance or speech. The purpose of this study was to compare the use of secondary surgery between cleft centers. METHODS: This retrospective cohort study included 130 children with complete unilateral cleft lip and palate treated consecutively at 4 cleft centers in North America. Data were collected on all lip, palate, and nasal surgeries. Nasolabial appearance was rated by a panel of judges using the Asher-McDade scale. Risk of secondary surgery was compared between centers using the log-rank test, and hazard ratios estimated with a Cox proportional hazards model. RESULTS: Median follow-up was 18 years (interquartile range, 15-19). There were significant differences among centers in the risks of secondary lip surgery (P < 0.001) and secondary rhinoplasty (P < 0.001). The cumulative risk of secondary lip surgery by 10 years of age ranged from 5% to 60% among centers. The cumulative risk of secondary rhinoplasty by 20 years of age ranged from 47% to 79% among centers. No significant differences in nasolabial appearance were found between children who underwent secondary lip or nasal surgery and children who underwent only primary surgery (P > 0.10). CONCLUSIONS: Although some cleft centers were significantly more likely to perform secondary surgery, the use of secondary surgery did not achieve significantly better nasolabial appearance than what was achieved by children who underwent only primary surgery.
RESUMEN
OBJECTIVES: The aim of the study was to investigate the prevalence of orofacial pain (OFP) among young adults (30-31 years old) and to determine the effect of childhood and adulthood risk factors on the occurrence of OFP. METHODS: Prospective cohort study to investigate dental and social effects of malocclusion and effectiveness of orthodontic treatment was conducted in Wales, United Kingdom. At 20-year follow-up 337 subjects aged 30-31 participated (74% from previous follow-up aged 19-20 and 33% from the baseline) and were asked about OFP. RESULTS: The prevalence of OFP was 23% (95% CI: 19%, 28%). Childhood factors, socio-demographic, lifestyle, health behavior factors, history of orthodontic treatment and tooth wear were not associated with OFP. Participants with OFP were more likely to report that their teeth did not fit together properly [odds ratio (OR) = 12.4, 95% CI: 2.7-56.5) and reported previous trauma to the jaws (2.3; 1.3-4.2). Both diurnal and nocturnal teeth clenching and grinding were significantly associated with OFP (3.1; 1.4-7.1). Participants with frequent headaches had increased risk of having OFP (3.7; 1.6-8.4) while having reported 4-10 types of pain in other parts of the body other than the head, was associated with OR = 9.2 (3.7-23.0). An increased tendency to have OFP was seen in those individuals with higher levels of psychological distress (2.3; 1.4-3.9), high score on Life Event Inventory (2.6; 1.3-5.3), depressive symptoms (2.2; 1.2-4.0) and stress (2.2; 1.2-4.0). High self-esteem associated with lower risk of OFP (0.5; 0.3-0.9). CONCLUSIONS: This study shows that OFP is frequently reported by young adults aged 30-31 and supports a multifactorial etiology with factors from many domains, including local mechanical factors, psychological and co-morbidities. However, none of the childhood factors considered in this study were associated with OFP in adulthood.

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 calculate the amount of treatment and associated travel experienced by five groups of patients treated at different centers. (This data is related to outcomes and patient/parent satisfaction in subsequent papers in this series). DESIGN: A longitudinal cohort study where results were previously reported at 9 years and follow-up measurements were obtained for 12 and 17 years. SETTING: Multidisciplinary cleft services in Northern Europe. SUBJECTS: 127 consecutively treated individuals with repaired unilateral complete cleft lip and palate. MAIN OUTCOME MEASURES: Numbers of surgeries and outpatient visits, number of visits, and treatment duration for early orthopedics and orthodontic treatment, associated travel time and difficulties. RESULTS: The mean number of operations per center ranged from 3.5 to 6; length of orthodontic treatment from 3.3 to 8.5 years, and attendance from 49 to 94 visits; and for early orthopedics, 0 to 15 months of treatment, 0 to 17 visits, and 0 to 146 days in hospital. CONCLUSION: Protocols for the management of complete unilateral cleft lip and palate can vary dramatically in the burden of treatment imposed.
