Growth Outcomes Audit for Unilateral Cleft Lip and Palate (UCLP) After 2-stage Palate Repair.

PURPOSE: To assess the impact of 1 and 2-stage palatoplasty protocol on the dental arch relationships in unilateral cleft lip and palate (UCLP) in a single center. METHODS: Our study consisted of 349 individuals divided into 2 groups according to the palatoplasty protocol. Two-stage group comprised 169 subjects with UCLP (mean age: 6.9 y, 110 male and 59 female) who underwent lip, nasal ala, and anterior palate repair with vomer flap from 3 to 6 months (first surgery stage). Soft palate repair occurred from 12 to 18 months (second surgery stage). The one-stage group comprised 180 subjects with UCLP (mean age: 7.2 y, 108 male and 72 female) who underwent 1-stage palatoplasty. Dental models were evaluated by 3 experienced orthodontists applying Goslon Yardstick and the 5-year-old index (FYOI). The influence of the palatoplasty technique and surgeon factor on the interarch relationship was evaluated. The weighted Kappa was used to assess intraexaminer and interexaminer agreements for comparisons of dental arch relationships. Intergroup comparisons were conducted using the χ 2 test ( P <0.05). RESULTS: The intraexaminer reliability was very good (0.81 to 0.98) and interexaminer reliability varied from satisfactory to very good (0.56 to 0.83). The mean occlusal index of the 2-stage and 1-stage groups was 2.77 and 3.03, respectively. The variability of the mean index between surgeons varied from 2.38 to 3.2 in the 2-stage group and 2.91 to 3.2 in the 1-stage group. There were significant differences in the frequency of Goslon 5 index ( P =0.002) between groups, with the 2-stage group presenting less cases (1.18%) than the group 1-stage (11.11%). CONCLUSION: The interarch relationship was similar for both palate repair protocols. Two-stage palatoplasty showed a decreased prevalence of Goslon index 5.

Outcomes of permanent canines on the cleft side after secondary alveolar grafting using different materials in complete unilateral cleft lip and palate.

The prevalence of impaction of the permanent canine on the cleft side (PCCS) ranges from 12-35% after alveolar bone grafting (ABG). PCCSs usually develop above other permanent teeth in the alveolar process, gradually becoming vertical until they reach the occlusal plane. The type of cleft, hypodontia of lateral incisor on the cleft side, slower PCCS root development, and genetic factors are predictors of impaction and/or its ectopic eruption. To compare the behavior of PCCS in individuals with complete unilateral cleft lip and palate (UCLP) subjected to secondary alveolar grafting (SAG) with different materials. This retrospective longitudinal study analyzed 120 individuals undergoing SAG with iliac crest bone, rhBMP-2, and mandibular symphysis. The individuals were selected at a single center and equally divided into three groups. Panoramic radiographs were analyzed by the Dolphin Imaging 11.95 software to measure PCCS angulation and PCCS height from the occlusal plane at two different timepoints. No statistical significance was found between grafting materials (P=0.416). At T1, the PCCS height from the occlusal plane was greater for rhBMP-2 and mandibular symphysis compared to iliac crest bone. The lateral incisor on the cleft side was not related to success or lack of eruption of PCCS (P=0.870). Impaction rates of PCCS were similar for the materials studied. Absence of the lateral incisor on the cleft side did not prevent spontaneous eruption of PCCSs.

Does the rehabilitation treatment predispose the patient with cleft to endodontic treatment?

Aim: to verify the relation between endodontic treatment of teeth adjacent to the cleft area and the rehabilitation of patients with unilateral cleft lip and palate, at the Hospital for Rehabilitation of Craniofacial Anomalies. Methods: the present split-mouth study was composed of 406 individuals with complete unilateral cleft lip and palate who had completed the rehabilitation process in a single tertiary cleft center (55.9% males). The information was collected from the dental history on the patients' records and radiographs. The frequency of endodontic treatment in the upper incisors and canines was calculated for the cleft and non-cleft sides. The comparison between sides was performed by the chi-square test (p <0.05). Results: endodontic treatment was more frequent in teeth adjacent to the cleft than in contralateral teeth. The frequency of endodontic treatment in at least one tooth adjacent to the cleft was 18.97%, and 11.6% on the contralateral side. It was observed that endodontic treatment was necessary in 63.5% of patients who had been submitted to orthodontic treatment, 42.4% of those rehabilitated with fixed partial dentures and 12.0% of patients who underwent dental reshaping of teeth adjacent to the cleft. The treatments performed included vital pulp therapy (46.1%), non-vital pulp therapy (46.8%) and endodontic retreatment (7.1%). Conclusion: in individuals with complete cleft lip and palate, teeth close to the bone defect area and used for rehabilitation treatment presented greater need of endodontic intervention

Objective: Congenital defects, including cleft lip and palate, increase the morbidity and mortality in the affected population. This study aimed to determine the prevalence of cleft lip and palate in the city of Bauru, Brazil, by evaluation of registry in the Brazilian Livebirth Certificate (DNV) and the Information System on Livebirths (SINASC), and analyzed the concordance of diagnosis compared with registries of the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC/USP), located in the same city. Material and Methods: This retrospective observational study comprised analysis of all DNVs and identification of individuals with clefts born and living in Bauru, comparing with data from HRAC/USP. The prevalence was calculated by dividing the number of children born with clefts in the study period by the total number of livebirths registered. The reporting of different types of clefts was compared by the chi-square test. Results: Overall, 50,898 DNV were evaluated, among which there were 25 reported cases of cleft lip and/or palate. In the same period, HRAC/USP registered 77 cases born in Bauru, representing 67.5% of underreporting of the occurrence of clefts. Cleft palate was the most prevalent (34.9%), followed by cleft lip and palate (31.7%) and cleft lip (30.2%), mostly affecting males (58.5%). The reporting of cleft palate (16.12%) was lower compared to cleft lip (43.75%) and cleft lip and palate (54.54%). Conclusion: The study revealed predominance of cleft palate, with significant underreporting of clefts in the public health system, especially for cleft palate as compared to cleft lip and cleft lip and palate (AU)

Hyoid Bone Position and Head Posture in Patients With Richieri-Costa Pereira Syndrome (EIF4A3 Mutations).

Robin sequence with cleft mandible and limb anomalies, known as Richieri-Costa-Pereira syndrome (RCPS), is an autosomal recessive acrofacial dysostosis characterized by mandibular cleft and other craniofacial anomalies and respiratory complications. The aim of this cross-sectional study was to describe the hyoid and head posture of 9 individuals with RCPS using cephalometric measurements and provide a discussion about its implications in obstructive sleep apnea syndrome (OSAS). The study was conducted on lateral cephalograms of patients with RCPS and 9 selected age-matched controls in tertiary cleft center in Brazil. The cephalograms were digitized and analyzed on a software to obtain the vertical and horizontal hyoid position, its relationship with the mandible and the relation of the cranial base and postvertebral line. The t test was used for analysis of means and Levene's test for equality of variances.Cephalometric measurements H-S (vertical distance between hyoid bone and sella) (Supplemental Digital Content, Figure 1, http://links.lww.com/SCS/B247) and H-C4lp (horizontal position of the hyoid in relation to the post-pharyngeal space) showed statistically significant difference compared to controls (P < 0.05). Therefore, the hyoid bone was more inferiorly and posteriorly positioned in the study group compared with the control group. The vertebrae measurements did not present differences compared to controls. The described position of hyoid bone could be involved in the severe OSAS of RCPS patients.

Craniofacial Morphology in Patients With Opitz G/BBB Syndrome.

OBJECTIVE: To compare the cephalometric characteristics of patients with and without Opitz G/BBB syndrome type I. DESIGN: Cross-sectional, case-control study. SETTING: Tertiary cleft center in Brazil. PARTICIPANTS: Eighteen individuals with Opitz G/BBB syndrome with complete bilateral cleft lip and palate (BCLP), compared to 18 individuals with nonsyndromic complete cleft lip and palate and 18 individuals without malformations, matched for gender and age. INTERVENTIONS: Pretreatment lateral cephalograms of all patients were manually traced and digitized for achievement of linear and angular measurements. MAIN OUTCOME MEASURES: Analysis of variance or Kruskal-Wallis followed by Tukey tests were used for intergroup comparisons at a significance level of P < .05. RESULTS: Individuals with Opitz G/BBB syndrome exhibited alterations in SNGn, P-Co, and N'-Pr/Po-Or that were not attributable to BCLP. Co-Go, Sella-Nasion-Supramentale, ANB (maxillo-mandibular relationship), and anterior nasal spine-posterior nasal spine (ANS-PNS)/U1A-U1T were significantly different in both G/BBB and BCLP groups compared to control, but not different between G/BBB and BCLP groups. Anterior nasal spine-posterior nasal spine/Go-Gn, ANS-PNS, V-Upper pharyngeal wall, and U-lower pharyngeal wall were different in nonsyndromic BLCP compared to nonsyndromic controls and Opitz G/BBB group. CONCLUSION: Patients with Opitz G/BBB syndrome exhibited some unique cephalometric alterations compared to patients with nonsyndromic complete BCLP and controls.

Relação entre reabsorções dentárias e enxerto alveolar em dentes adjacentes à área da fissura / Relationship between root resorption and alveolar graft in teeth adjacent to the cleft lip and palate area

Objetivo: avaliar, radiograficamente, a prevalência, extensão e severidade da reabsorção dentária em dentes adjacentes à área de fissura após enxerto ósseo alveolar. Métodos: radiografias de 200 indivíduos com fissura unilateral e bilateral, alveolar e palatina, foram analisadas para se investigar a presença de reabsorção dentária relacionada com o enxerto ósseo. No total, 1.315 radiografias foram analisadas (periapical, oclusal e radiografias panorâmicas), obtidas a partir de 200 indivíduos com fissura labiopalatina unilateral e bilateral completa ubmetidos a cirurgia de enxerto, disponíveis a partir dos arquivos da Seção de Radiologia do HRAC-USP. Resultados: entre os 200 indivíduos, 33 tinham reabsorções dentárias externas. Dessas, 15 estavam presentes nas radiografias pré-operatórias e 18 só depois do enxerto ósseo. No geral, 30 reabsorções localizaram- se no terço apical da raiz e 3 no terço cervical; o incisivo central esquerdo foi o mais afetado. Não foram observadas reabsorções dentárias no terço médio da raiz e nenhuma reabsorção afetou mais de um terço. Não existiu diferença estatisticamente significativa entre a idade do paciente durante a cirurgia de enxerto ósseo e a presença de reabsorção dentária externa. Conclusões: a prevalência da reabsorção dentária em dentes adjacentes à área da fissura em indivíduos submetidos a enxerto ósseo foi baixa (16,5%). O terço apical da raiz foi o local mais frequente de reabsorção radicular externa, e não houve reabsorções afetando mais de um terço da raiz. (AU)

Male individuals with Robin Sequence: emerging significant association with ABO and RhD blood group phenotypes.

BACKGROUND: This study investigated the association of Robin Sequence with ABO and RhD blood group phenotypes. METHODS: A retrospective cross-sectional study was performed of a cohort of Robin Sequence patients of the Hospital de Reabilitação de Anomalias Craniofaciais - Universidade de São Paulo (USP), Brazil. The study group was composed of 339 individuals of both genders with Robin Sequence referred for specific treatment. A control group was composed of 1780 individuals without syndromes. The groups were compared using the Pearson' chi-square test (χ 2) with statistical significance being defined for an alpha error of 5% (p-value < 0.05). RESULTS: A comparison of gender found a significant difference for the AB phenotype between groups (p-value = 0.007). Comparing blood type by gender there was no significant difference within the same group (p-value = 0.117 and 0.388 respectively, for Robin Sequence and the control group). When comparing the AB blood type between groups, there was no difference for females (p-value = 0.577), but there was a significant difference for males (p-value = 0.0029). CONCLUSIONS: This study showed that the population with Robin Sequence had different patterns related to gender concerning the phenotypic distribution of ABO and RhD blood group phenotypes. Robin Sequence is more common among females. The AB phenotype was significantly higher in males with Robin Sequence than in males of the Control Group. The prevalence of the RhD-negative phenotype is higher in individuals with Robin Sequence. This result suggests a possible association of ABO and RhD phenotypes with Robin Sequence that should be better investigated by molecular studies, as it deserves greater attention.

Comparative Analysis of the Efficacy of Dental Plaque Removal Between Manual and Powered Toothbrushes in Individuals With Syndactyly.

OBJECTIVE: To compare the efficacy of dental plaque removal between manual and powered toothbrushes in individuals with syndactyly. MATERIAL AND METHODS: Seventeen patients with Apert syndrome aged 11 to 30 years. The efficacy of toothbrushing was evaluated by the O'Leary plaque index at 2 periods: initial (before toothbrushing) and final (immediately after toothbrushing), using manual toothbrush (Colgate Twister) and powered toothbrush (Colgate Actibrush). Means were compared by the ANOVA test at a significance level of 5%. RESULTS: The reduction in the plaque index was different for each type of toothbrush (interaction factor between manual and powered toothbrushes and initial and final periods, P = 0.026). The powered toothbrush provided greater reduction of dental plaque than the manual toothbrush. CONCLUSION: In individuals with syndactyly, both manual and powered toothbrushes allowed significant plaque reduction on tooth surfaces; however, the powered toothbrush exhibited greater efficacy of plaque removal compared with the manual toothbrush.

Cephalometric Findings in Nine Individuals With Richieri-Costa-Pereira Syndrome.

The Richieri-Costa-Pereira syndrome (RCPS) is an autosomal-recessive acrofacial dysostosis caused by mutations in EIF4A3, characterized by mandibular cleft comprising other craniofacial anomalies and limb defects such as cleft palate/Robin Sequence, microstomia, absence of mandibular central incisors, minor ear anomalies, clubfeet and first and 5 ray defects. The findings from this study are useful for better understanding the morphological consequences of disorders of EIF4A3, and having a better picture of the anatomic characteristics of the syndrome for a better therapeutic planning. Twenty-four angular and linear variables were measured to assess anteroposterior and vertical (superior-inferior) position of the cranial base, maxilla, mandible, and facial profile. The cephalometric radiographic analysis was performed on 9 individuals with RCPS, obtained at a mean age of 10.3 years, and compared with randomly selected age-matched 9 controls, without clefts and with well-balanced faces, with mean age of 10.6 years (both groups range 8.1 to 13.7 years). t test was used for analysis of means and Levene test for equality of variances. The syndrome group presented severe mandibular hypoplasia and retrognathism (P = 0.009, P = 0.001), greater facial convexity (N'PnPog and N'SnPog, P < 0.05) in syndrome group compared with the control group (P = 0.003, P = 0.004). In conclusion, in the RCPS group, most craniofacial defects affect the lower facial third, considering the severely affected mandible.

The maxillary lateral incisor in the rehabilitation of cleft lip and palate.

Objective This study analyzed the maintenance of lateral incisors in the dental rehabilitation of individuals with cleft lip and palate. Material and Methods The study was conducted on a tertiary craniofacial center and comprised retrospective analysis of panoramic and periapical radiographs of Caucasoid individuals with non-syndromic complete unilateral cleft lip and palate, analyzing all radiographs available on the records of each individual, from the first to the last up to 12 years of age. Overall, 2,826 records were reviewed to achieve a sample of 1,000 individuals. Among these, 487 individuals presented the permanent lateral incisors on both cleft and non-cleft sides, which were included in this study. Results The results were evaluated in percentages and by descriptive statistics. The association between maintenance of the lateral incisor and timing of alveolar bone graft were analyzed by the t test. Among the 487 individuals, 265 had not completed treatment, 62 presented insufficient information, and 44 concluded the treatment elsewhere. Among the remaining 116 individuals, the lateral incisor was extracted from 88 (75.86%) of them on the cleft side (CS) and from 23 (19.83%) people on the non-cleft side (NCS). The age at accomplishment of alveolar bone graft was significantly associated with maintenance of the lateral incisor on the cleft side (p<0.01). Most extractions were indicated because of the inadequate positioning on the CS and for midline correction on the NCS. Rehabilitation was primarily completed by orthodontic movement (53 individuals on the CS and 13 individuals on the NCS). Conclusion In conclusion, the lateral incisor on the cleft side was not maintained in most individuals. Positive relationship was observed between extraction of the lateral incisor and age at accomplishment of the alveolar bone graft, suggesting the need to anticipate the initial radiographic evaluation to enhance its maintenance and reduce the procedures required for rehabilitation.

Evaluation of photobiomodulation therapy associated with guided bone regeneration in critical size defects. In vivo study.

The repair of bone defects raises the interest of investigators in several health specialties. Grafting techniques with bone substitutes and laser therapies have been investigated to replace autogenous bone and accelerate the bone healing process. Objective To evaluate the effect of photobiomodulation therapy (PBMT) associated with guided bone regeneration (GBR) in critical size defects. Material and Methods The study was conducted on 80 male rats (Rattus norvegicus albinus, Wistar) submitted to surgical creation of a critical size defect on the calvaria, divided into eight study groups: group C (control - only blood clot); group M (collagen membrane); group PBMT (photobiomodulation therapy); group AB (autogenous bone); group AB+PBMT; group AB+M; group PBMT+M; group AB+PBMT+M. The animals were killed 30 days postoperatively. After tissue processing, bone regeneration was evaluated by histomorphometric analysis and statistical analyses were performed (Tukey test, p<0.05). Results All groups had greater area of newly formed bone compared to group C (9.96±4.49%). The group PBMT+M (achieved the greater quantity of new bone (64.09±7.62%), followed by groups PBMT (47.67±8.66%), M (47.43±15.73%), AB+PBMT (39.15±16.72%) and AB+PBMT+M (35.82±7.68%). After group C, the groups AB (25.10±16.59%) and AB+M (22.72±13.83%) had the smallest quantities of newly formed bone. The area of remaining particles did not have statistically significant difference between groups AB+M (14.93±8.92%) and AB+PBMT+M (14.76±6.58%). Conclusion The PBMT utilization may be effective for bone repair, when associated with bone regeneration techniques.

Influência da oleosidade resultante da lubrificação da caneta de alta rotação na adesão da resina composta ao esmalte / Influence of oil contamination resulting from lubrication of high-speed handpieces in the bonding of composite resin to enamel

A restauração de dentes por sistemas adesivos é rotina em odontologia. O tratamento do esmalte inicia-se pela profilaxia e asperização dos prismas. A manobra é feita com brocas adaptadas à canetas de alta ou baixa rotação as quais devem ser lubrificadas frequentemente. Diversos fatores podem provocar falhas nas restaurações, entre eles a contaminação por oleosidade. A proposta do trabalho foi verificar a influência da lubrificação das pontas de alta rotação na adesão de resinas compostas ao esmalte. Foram confeccionados 30 corpos de provas, constituídos de cilindros de PVC, nos quais se incluiu fragmento da superfície vestibular de dente bovino em resina acrílica autopolimerizável, de maneira paralela ao solo, com área suficiente para a colagem de braquete de 9 mm2. A amostra foi dividida em três grupos de 10. No primeiro (A), cada braquete foi colado de maneira convencional com uma asperização prévia do esmalte realizada com caneta sem lubrificação. No segundo (B), foi realizada asperização com caneta lubrificada e pré-acionada por 30 segundos. E no terceiro (C), a asperização foi feita imediatamente após a lubrificação. Cada braquete foi submetido ao teste de tração. Todas as falhas foram coesivas, apresentando valores médios de 73,18N para o grupo A, 75,90N para o B e 91,45N para o C. O tratamento estatístico não mostrou diferença significativa entre os grupos. De acordo com o método instituído não houve influência da lubrificação das pontas de alta rotação na adesão de resinas compostas ao esmalte (AU).

The use of adhesive systems is a routine procedure in restorative dentistry. Enamel treatment starts with prophylaxis and abrasion of enamel prisms. This is performed using drills adapted to high or slow speed handpieces which must be frequently lubricated. Many factors may produce failure in tooth restoration, among them is the contamination by oil. The purpose of this study was to assess the influence of high speed handpiece lubrication in bond strength of composite resin to enamel. Thirty specimen were made constituted of PVC cylinders, in which were included fragments of the vestibular surface of the bovine tooth in self-polymerized acrylic resin parallel to the floor with sufficient area for bonding the 9 mm2 bracket. The samples were divided randomly into three groups of 10. In the first group (A), the bracket was bonded using the conventional way and enamel abrasion was previously performed with an unlubricated handpiece. In the second one (B), abrasion was performed with a lubricated handpiece which was run on air for 30 seconds and in the third group (C), abrasion was made immediately after lubrication. A tensile test was carried out for each bracket. All failures were cohesive with mean values of 73,18N (group A), 75,90N (group B) and 91,45N (group C). Statistical tests detected no significant differences between the groups. According to the established method, there was no influence of high speed handpiece lubrication on bond strength of composite resin to enamel (AU).

Accumulated knowledge and prevention practices in oral health.

This text begins by reflecting on health promotion and equity/ inequity. In health, inequity is understood as a political concept that has moral implications and that is committed to social justice. A discussion follows on some issues regarding the risk and prevention of diseases, still considered a hegemonic practice, and lack of experience in oral health-care, bearing in mind the concept of vulnerability. The risk is probabilistic and involves the mathematical chances of acquiring a disease in a certain group, whereas vulnerability addresses the potential of acquiring or not acquiring a disease in a certain environment. The need for systematic studies on determinants is stressed, with the ultimate goal of improving health and reducing inequities, and with the concern and political intention of including health equity in governmental policies.
