OBJECTIVE:The study of dental development in individuals born with cleft lip and palate (CLP) serves to determine when orthodontic intervention should start. To evaluate the permanent second molar development in children born with cleft lip and palate according to Demirjian's and Nolla's methods. METHODOLOGY:Out of a total of 513 digital panoramic radiographs, 113 pairs of children aged 3 to 16 years were selected. The exams were from children born with or without cleft lip and palate, of the same sex, with an age difference of up to 30 days. The images were analyzed by three examiners and reliability was checked through intra-examiner agreement by the Kappa test. The data were analyzed by Wilcoxon's and Mann-Whitney tests according to each dataset. RESULTS:The findings indicated delayed development of the permanent second molars in children with CLP (P<0.001). The development of the right permanent second molar was delayed compared to the left molar in children with CLP. Moreover, mandibular teeth showed significantly earlier development than maxillary teeth in both the case and control groups. There was no significant difference in the development of permanent second molars between sexes. CONCLUSION:Children with CLP presented delay in the development of permanent second molars.


目的: 研究唇腭裂 (CLP) 出生个体的牙齿发育,以确定何时开始正畸干预。根据Demirjian 's和Nolla' s方法评估出生的唇腭裂患儿的永久性第二磨牙发育情况。 方法: 在总共 51 3 张数字化全景x线片中,选择 11 3 对 3 ~ 16 岁的儿童。这些检查来自出生时患有或不患有唇腭裂的儿童,性别相同,年龄相差长达 30 天。由三名检查者分析图像,并通过Kappa test通过检查者内一致性检查可靠性。根据每个数据集,通过Wilcoxon 's和Mann-Whitney检验分析数据。 结果: CLP患儿永久性第二磨牙发育延迟 (P<0.001)。与CLP患儿的左磨牙相比,右永久性第二磨牙的发育延迟。此外,在病例组和对照组中,下颌牙的发育均明显早于上颌牙。永久性第二磨牙的发育在性别间无显著差异。 结论: CLP患儿表现为永久性第二磨牙发育延迟。

METHODS:BACKGROUND:The anterior oronasal fistulae neighboring the alveolar cleft could persist or reappear after the alveolar reconstruction with cancellous bone grafting. The persistent symptomatic anterior oronasal fistulae need to be repaired, but surgery remains a challenge in cleft care. Surprisingly, this issue has rarely been reported in the literature. The purpose of this long-term study was to report a single surgeon experience with a therapeutic protocol for persistent symptomatic anterior oronasal fistula repair. METHODS:This is a retrospective study of consecutive patients with Veau type III and IV clefts and persistent symptomatic anterior oronasal fistulae managed according to a therapeutic protocol from 1997 to 2018. Depending on fistula size, patients were treated with local flaps associated with an interpositional graft or two-stage tongue flaps (small/medium or large fistulae, respectively). The surgical outcomes were classified as "good" (complete fistula closure with no symptoms), "fair" (asymptomatic narrow fistula remained), or "poor" (failure with persistent symptoms). RESULTS:Forty-four patients with persistent symptomatic anterior oronasal fistulae were reconstructed with local flaps associated with interpositional fascia or dermal fat grafting (52.3%) or two-stage tongue flaps (47.7%). Most of patients (93.2%) presented "good" outcomes, ranging from 87% to 100% (local and tongue flaps, respectively). Three (6.8%) patients presented symptomatic residual fistula ("poor" outcomes). CONCLUSIONS:For the repair of persistent symptomatic anterior oronasal fistulae, this therapeutic protocol provided satisfactory outcome with low fistula recurrence rate.

METHODS:OBJECTIVE:Methadone is a vital treatment for women with opioid use disorder in pregnancy. Previous reports suggested an association between methadone exposure and Pierre Robin sequence (PRS), a rare craniofacial anomaly. We assessed the association between gestational methadone exposure and PRS. DESIGN/SETTING:This case-malformed control study used European Surveillance of Congenital Anomalies population-based registries in Ireland, the Netherlands, Italy, Switzerland, Croatia, Malta, Portugal, Germany, Wales, Norway and Spain, 1995-2011. PATIENTS:Cases included PRS based on International Classification of Disease (ICD), Ninth Edition-British Paediatric Association (BPA) code 75 603 or ICD, Tenth Edition-BPA code Q8708. Malformed controls were all non-PRS anomalies, excluding genetic conditions, among live births, fetal deaths from 20 weeks' gestation and terminations of pregnancy for fetal anomalies. An exploratory analysis assessed the association between methadone exposure and other congenital anomalies (CAs) excluding PRS. Methadone exposure was ascertained from medical records and maternal interview. RESULTS:Among 87 979 CA registrations, there were 127 methadone-exposed pregnancies and 336 PRS cases. There was an association between methadone exposure and PRS (OR adjusted for registry 12.3, 95% CI 5.7 to 26.8). In absolute terms, this association reflects a risk increase from approximately 1-12 cases per 10 000 births. A raised OR was found for cleft palate (adjusted OR 5.0, 95% CI 2.7 to 9.2). CONCLUSIONS:These findings suggest that gestational methadone exposure is associated with PRS. The association may be explained by unmeasured confounding factors. The small increased risk of PRS in itself does not alter the risk-benefit balance for gestational methadone use. The association with cleft palate, a more common CA, should be assessed with independent data.

METHODS::Orthopedic treatment to improve deficient maxillary growth of cleft lip and palate patients is an important part of treatment. The success of this treatment is strongly dependent on the time of initiation of therapy. There has been a large controversy in the available literature regarding the skeletal age of these patients. The aim of the present study was to compare the skeletal age of cleft lip and palate patients with normal individuals.37 unilateral and 14 bilateral cleft lip and palate patients and 47 healthy individuals participated in this cross-sectional study. The patients were classified into 8 to 10 and 11 to 14-year-old individuals. Cervical vertebral maturational stage of participants was evaluated in the lateral cephalometry. The skeletal age of cleft lip and palate patients was compared with normal controls. Chi-square was used for statistical analysis. There was not a significant difference in the skeletal developmental stage of unilateral and bilateral cleft compared to their normal peers according to their age and sex. Also, significant difference in skeletal maturational stage of cleft lip and palate patients was not found between boys and girls (P = 0.8). Similarly, no significant difference was found in the skeletal age of the 3 studied groups without considering the age and sex of participants (P = 0.5). Regarding the similar skeletal maturational stage of cleft lip and palate patients with normal controls in our study, their maxillofacial orthopedic treatment can be initiated at similar time to normal peers.
