Introducción: el colapso trasversal maxilar se define como el desarrollo insuficiente del maxilar en sentido trasversal. Es uno de los problemas más perjudiciales en el crecimiento facial y la integridad de las estructuras dentoalveolares. Objetivo: identificar la cantidad colapsos transversales del maxilar en tomografía computarizada de haz cónico (CBCT) y la decisión terapéutica propuesta. Material y métodos: se examinó un total de 52 expedientes con CBCT del Postgrado de Ortodoncia de la Universidad Autónoma de Sinaloa determinándose los casos de colapso trasversal maxilar a través del análisis de Penn. La información recolectada fue capturada en una base de datos, utilizando el programa Excel, y se analizó con un modelo de regresión logística. Resultados: se encontraron 32 pacientes con colapso trasversal maxilar de un total 44 pacientes atendidos. El modelo de regresión logística no mostró asociación entre la presencia de colapso maxilar y el uso de tratamientos con el que resolvieran el colapso maxilar. Conclusión: existe gran cantidad de pacientes con colapso maxilar; sin embargo, el plan de tratamiento no muestra tratar de resolver estos colapsos maxilares (AU)

Introduction: transverse maxillary collapse is defined as insufficient development of the maxilla in a transverse direction. It is one of the most harmful problems in facial growth and the integrity of the dentoalveolar structures. Objective: identify the number of transverse collapses of the maxilla in cone beam computed tomography (CBCT) and the proposed therapeutic decision. Material and methods: a total of 52 records with CBCT of the orthodontics postgraduate course of the Autonomous University of Sinaloa UAS were examined, determining the cases of transverse maxillary collapse through the Pen analysis. The information collected was captured in a database using the Excel program and analyzed with a logistic regression model. Results: 32 patients with maxillary transverse collapse were found out of a total of 44 patients attended. The logistic regression model did not show an association between the presence of maxillary collapse and the use of treatments that resolved maxillary collapse. Conclusion: there is a large number of patients with maxillary collapse, however, the treatment plan does not show trying to resolve these maxillary collapses (AU)

Degree of Sagittal Suture Fusion, Cephalic Index, and Head Shape in Nonsyndromic Sagittal Craniosynostosis.

BACKGROUND: Sagittal craniosynostosis may present with complete or partial fusion of the sagittal suture, but relationships between degree of sagittal suture fusion and head shape are currently poorly described. The aim of this study was to characterize sagittal suture fusion patterns and determine associations with head shape in a cohort of patients with nonsyndromic sagittal craniosynostosis. METHODS: Patients with nonsyndromic sagittal craniosynostosis at a tertiary care center with available computed tomography imaging were included in this study. The anterior and posterior distances of sagittal suture patency were measured along 3-dimensional parietal bones. Degree of sagittal suture fusion was compared to head shape characteristics, including cephalic index (CI), frontal bossing, and occipital bulleting. RESULTS: Ninety patients (69 male) were included in this retrospective study. The sagittal suture was on average 85.6±20.1% fused, and 45 (50.0%) patients demonstrated complete fusion of the sagittal suture. CI was associated with increased degree of fusion for the anterior one-half (ρ=0.26, P =0.033) and anterior one-third (ρ=0.30, P =0.012) of the sagittal suture. Complete fusion of the anterior one-third of the sagittal suture predicted higher CI (ß=13.86, SE=6.99, z =-0.25, P =0.047). Total degree of sagittal suture fusion was not predictive of CI or head shape in any analysis. CONCLUSIONS: Decreased fusion of the anterior one-third of the sagittal suture, but not total suture, may paradoxically predict increased severity of scaphocephaly as quantified by CI in nonsyndromic sagittal craniosynostosis.

Discrepancia negativa transversal del maxilar y factores asociados en pacientes con necesidad de cirugía ortognática / Negative transverse maxillary discrepancy and associated factors in patients requiring orthognathic surgery

Introducción: La discrepancia transversal de las arcadas es un problema esquelético poco estudiado en personas con necesidad de tratamiento ortodóncico quirúrgico. Objetivo: Caracterizar a pacientes con discrepancia negativa transversal del maxilar y necesidad de tratamiento por cirugía ortognática. Métodos: Se realizó un estudio descriptivo de corte transversal en 25 expedientes clínicos de pacientes que acudieron al servicio de cirugía maxilofacial del Hospital Clínico Quirúrgico Hermanos Ameijeiras, con discrepancia negativa transversal del maxilar y necesidad de cirugía ortognática entre enero de 2016 y enero de 2020. Se estudiaron los casos por medio de variables cualitativas divididas en epidemiológicas, características faciales y mediciones dentarias. Para el análisis se confeccionaron cuadros estadísticos y como medidas de resumen se utilizaron frecuencias absolutas y relativas. Resultados: La frecuencia de la discrepancia negativa del maxilar fue de 13,3 por ciento. Los pacientes de piel blanca fueron los más afectados (80 por ciento) y el principal motivo de consulta fue estético (68 por ciento). La asimetría del tercio inferior y el perfil cóncavo estuvieron presentes en el 44 por ciento y 36 por ciento de los casos respectivamente. Se observó alta frecuencia de pacientes con el tercio inferior aumentado (76 por ciento), mordida cruzada posterior (48 por ciento), mordida abierta anterior (75 por ciento), apiñamiento en la arcada inferior (63,3 por ciento) y lingualización del incisivo inferior (72 por ciento). Conclusiones: La discrepancia negativa transversal del maxilar es frecuente en personas con necesidad de cirugía ortognática y con gran afectación estética. Se observó mayor predisposición a padecerla en pacientes de piel blanca(AU)

Introduction: Transverse discrepancy of the arches is a skeletal problem not sufficiently studied in persons requiring surgical orthodontic treatment. Objective: Characterize patients with negative transverse maxillary discrepancy requiring surgical orthognathic surgery. Methods: A descriptive cross-sectional study was conducted of 25 medical records of patients attending the maxillofacial surgery service at Hermanos Ameijeiras Clinical Surgical Hospital with negative transverse maxillary discrepancy requiring orthognathic surgery from January 2016 to January 2020. The cases were studied with qualitative variables divided into epidemiological, facial features and dental measurements. Analysis was based on statistical charts. The summary measurements used were absolute and relative frequencies. Results: The frequency of negative maxillary discrepancy was 13.3 percent. White skin patients were more commonly affected (80 percent). The main concern was aesthetic (68 percent). Lower third asymmetry and a concave profile were present in 44 percent and 36 percent of the cases, respectively. A high frequency was observed of patients with an augmented lower third (76 percent), posterior crossbite (48 percent), anterior open bite (75 percent), lower arch crowding (63.3 percent) and lower incisor lingualization (72 percent). Conclusions: Negative transverse maxillary discrepancy is common among patients requiring orthognathic surgery for large aesthetic alterations. White skin patients were found to be more prone to present this disorder(AU)

Utility of Preoperative Helmet Molding Therapy in Patients With Isolated Sagittal Craniosynostosis.

ABSTRACT: The purpose of this study was to review our institution's experience using helmet molding therapy in children with isolated non-syndromic sagittal craniosynostosis before placement of cranial springs and provide objective measurements of craniometric changes to help determine its role in treatment.Patients who underwent preoperative helmet molding therapy for sagittal craniosynostosis were retrospectively reviewed. Three-dimensional surface tomography scans were used to measure head circumference, cranial width, cranial length, cranial index (CI), and cranial vault asymmetry.Seventeen patients underwent orthotic helmeting therapy before spring mediated cranial vault expansion. Patients spent a median of 48 days (interquartile range [IQR] 32, 57) in preoperative orthotic helmeting therapy. There were increases in both cranial width and length post-helmeting (median: 107.5 mm [IQR 104.8, 110.4] versus 115.6 mm [IQR 114.5, 119.3]; P < 0.001) (median: 152.8 mm [IQR 149.2, 154.9] versus 156.8 mm [IQR 155.0, 161.5]; P < 0.001), respectively. There was a greater increase in cranial width (P = 0.015). Consequently, patients' CI improved after preoperative helmeting (median: 0.702 [IQR 0.693, 0.717] versus 0.739 [0.711, 0.752]; P < 0.001). There was no evidence of growth restriction from helmeting (pre-helmeting Head circumference [HC]: median 96.8 percentile [IQR 90.6, 99.9] versus post-helmeting HC: 98.7 percentile [IQR 94.7, 99.8]; P = 0.109).Preoperative helmeting in patients with non-syndromic isolated sagittal craniosynostosis can be used to improve CI before surgical correction. Significant benefits can be achieved in shorter preoperative helmeting durations than previously reported with no evidence of cranial growth restriction, which supports its feasibility and utility in children undergoing spring mediated cranial vault expansion.

RESUMEN Fundamento: Dentro de las anomalías de la oclusión que provocan afectación estética y funcional en los pacientes, se destaca el síndrome de clase III esqueletal de Moyers, cuyo diagnóstico debe ser preciso y precoz. Objetivo: Cuantificar la concordancia entre los criterios diagnósticos ortodóncicos y médicos en los portadores del síndrome de clase III esquelético de Moyers. Metodología: Se realizó un estudio observacional, descriptivo y transversal en la Clínica Estomatológica Provincial Docente "Mártires del Moncada" de Santiago de Cuba desde enero de 2018 hasta enero de 2020. Se estudiaron, por Ortodoncia y diferentes especialidades médicas seleccionadas, 15 pacientes de 8 a 18 años de edad diagnosticados clínica y cefalométricamente con clase III esqueletal de Moyers. Resultados: El nivel de acuerdo entre ortodoncia y las diferentes especialidades médicas fue leve con Oftalmología (Kappa=0.10), casi perfecta con Ortopedia (Kappa=1.00), pobre por Gastroenterología y por Otorrinolaringología (Kappa de 0.09 y 0.10 respectivamente), resultados estadísticamente significativos solo con Ortopedia. Conclusiones: Es evidente la marcada concordancia entre los diagnósticos ortodóncicos y ortopédicos en el síndrome de clase III esquelético, a diferencia del resto de las especialidades médicas; probablemente asociado a la no estandarización de las evaluaciones clínicas.

ABSTRACT Background: Among the occlusion anomalies that cause esthetic and functional affectation in patients, Moyers skeletal class III syndrome stands out, its diagnosis should be accurate and early. Objective: To quantify the concordance between orthodontic and medical diagnostic criteria in patients with Moyers skeletal class III syndrome.

Treatment of Sagittal Craniosynostosis Using Osteoplastic Parietal Craniotomy Flap With Distraction Osteogenesis: A Variation on Technique.

ABSTRACT: Late presentation sagittal craniosynostosis presents a unique challenge due to the decreased ability of the skull to repair the bony defects created by standard of care techniques. Distraction osteogenesis is a viable strategy to correct this defect in late presenting cases. The authors describe a variation in technique in which the temporalis muscle origin is retained, creating an osteoplastic bone flap with retained vascularity through the tem-poralis muscle. This may improve postoperative bony healing of bony defects in this compromised population. The authors present two patients who presented to them late with sagittal synostosis who were treated with distraction osteogenesis in which vascular continuity to the parietal bones is preserved through the temporalis muscle.

Tratamento orto-cirúrgico de paciente com sorriso gengival e padrão face longa ­ relato de caso / Orto-surgical treatment of patient with gummy smile and long face pattern ­ case report

Resumo Introdução: O padrão Face Longa é uma deformidade facial com aumento da altura facial anterior. Nesse padrão, verifica-se incompetência labial com contração da musculatura perioral. O crescimento dentoalveolar vertical excessivo provoca exposição gengival durante o sorriso, o que constitui a principal queixa do paciente. A prevalência do padrão Face Longa varia de 1,5% a 14,6% na população adulta e aproximadamente metade desses pacientes necessitam de intervenção cirúrgica. Objetivo: relatar o caso clínico de paciente com padrão Face Longa severo tratado com a abordagem ortodôntico-cirúrgica. Métodos: Após um breve tratamento ortodôntico pré-cirúrgico, o paciente foi submetido à cirurgia ortognática. Foi realizada impacção maxilar de 10mm com rotação de plano oclusal e mentoplastia. A tecnologia digital, com imagens tridimensionais, foi aplicada para planejar o tratamento e imprimir guias cirúrgicas. Resultados: O tratamento promoveu selamento labial passivo com exposição gengival adequada no sorriso e um perfil facial reto. A paciente mostrou-se muito satisfeita com os resultados estéticos e funcionais. Conclusão: O tratamento orto-cirúrgico em pacientes com padrão de crescimento vertical é uma excelente alternativa para corrigir a desarmonia esquelética e melhorar a estética facial e do sorriso, além disso, promove forte impacto positivo na qualidade de vida dos indivíduos. Essa abordagem, quando devidamente planejada por um profissional experiente e com o auxílio da tecnologia digital pode aumentar a previsibilidade e a estabilidade a longo prazo.(AU)

Abstract Introduction: The Long Face pattern is a facial deformity with increased anterior total facial height. In this pattern, there is lip incompetence, and when the lip seals, contraction of the perioral musculature can be evidenced. Excessive dentoalveolar growth leads to gingival overexposure during smile, which is the patient's main complaint. The prevalence of Long Face pattern ranges from 1,5% to 14,6% in adult population and approximately half of these patients require surgical intervention. Objective: to report a clinical case of a patient with severe Long Face pattern treated with an orthodontic-surgical approach. Methods: After a brief pre-surgical orthodontic treatment the patient underwent orthognathic surgery. It was performed a 10mm maxillary impaction with occlusal plane rotation and mentoplasty. The digital technology with three-dimensional images was ­ to plan the treatment and print surgical splints. Results: Treatment promoted passive lip seal with adequate smiling gingival exposure and a straight profile. Patient became very satisfied with the aesthetical and functional results. Conclusion: Ortho-surgical treatment in patients with vertical growth pattern is an excellent alternative to correct skeletal disharmony and improve facial and smile aesthetics, besides that it promotes a strong positive impact on the quality of life of individuals. This approach when properly planned by an experienced professional and with the aid of digital technology may increase predictability and long-term stability.(AU)

3D Assessment of the Correlation between Neonatal Morphology and Occlusal Outcomes in 5-Year-Old Patients with Complete Unilateral Cleft Lip and Palate

ABSTRACT Objective: To exploit 3D measurement technology to determine any correlation between neonatal palate morphology and occlusal outcomes at five years in patients receiving surgery for unilateral cleft lip and palate (CLP). Material and Methods: Twenty-nine neonatal and 5-year models treated by the same surgeon using the same protocol for CLP correction were scanned using a high-resolution structured-light scanner and stored in stl format. Dedicated software was used to make linear and surface area measurements on the neonatal models, and each digitized 5-year model was assigned a Five-Year-Old (5YO) index score on three separate occasions by the same investigator. Results: Minimum, maximum, mean, standard deviation and standard error were calculated for each variable considered, and the Pearson coefficient was used to identify any correlations between neonatal variables and 5YO scores. Linear regression analysis showed that the only variable to approach significance was the posterior width of the cleft, which showed an R2 equal to 0.111, indicating that it accounts for 11% of the variability of the 5YO index. There was no other appreciable correlation between linear measurements, surface areas, or their inter-relationships. Conclusion: There is no correlation between neonatal morphological characteristics and occlusal outcomes at 5 years in CLP patients treated via the surgical protocol considered.

Introdução: desproporções esqueléticas são consideradas casos extremos de variação da tipologia facial, caracterizadas por grandes alterações da oclusão associadas a modificações funcionais. O tratamento é orto-cirúrgico, com reconstrução das bases ósseas por meio de cirurgia ortognática. Após essa cirurgia, o acompanhamento fonoaudiológico auxilia o paciente no reconhecimento da nova face e nas readaptações das funcões de respiração, fala, mastigação e deglutição. Objetivo: apresentar relato de caso clínico de cirurgia ortognática, em seguimento longitudinal de 10 anos, por meio de análise das avaliações fonoaudiológicas. Relato do caso: mulher, 26 anos, portadora de deformidade craniofacial do tipo Classe III, prognata, com queixa estética e de mastigação, com indicação de cirurgia ortognática. Foram realizadas cinco avaliações fonoaudiológicas, sendo: a primeira na fase pré-operatória, segunda no 19º dia de pós-operatório, terceira após três meses de reabilitação fonoaudiológica, quarta após quatro meses de manutenção dos resultados obtidos e a quinta após 10 anos da intervenção cirúrgica. Em avaliação pré-cirúrgica foi registrada alteração no padrão miofuncional relacionado às funções de mastigação, deglutição, fala e respiração. Após terapia fonoaudiológica observou-se melhora da musculatura de lábios, bochecha, masseter e postura de língua, bem como na amplitude dos movimentos mandibulares. Em 10 anos observa-se estabilidade nos padrões funcionais de respiração, posicionamento de língua em repouso, organização do padrão da fala, articulação, deglutição, assim como na autoestima da paciente. Considerações finais: o tratamento fonoaudiológico associado à cirurgia ortognática e à ortodontia mostrou evoluções e eficácia, para nesse caso, atingir satisfação da paciente aos novos ajustes do padrão miofuncional.

Introduction: dentofacial deformities are seen as extreme cases of facial typology variation, characterized by major changes in occlusion associated with functional modifications. It requires an ortho-surgical treatment, in which the bone bases are reconstructed through orthognathic surgery. Treatment and monitoring are required after surgery with a Speech-language Pathologist (SLP) in order to assist patients in the recognition of their new faces and in the adjustments of orofacial functional patterns, avoiding negative interferences. Purpose: to report an orthognathic surgery clinical case in a 10-year longitudinal follow-up through the analysis of the SLP assessments. Case report: a prognathous 26-year-old woman with Class III craniofacial deformity, presenting aesthetic and chewing complaints with indication for orthognathic surgery. Five SLP ́s assessments were conducted, as follows: the first one, in the preoperative stage; the second, 19 days after the surgery; the third, after three months of SLP rehabilitation; the fourth, after four months of follow-up as maintenance of the results obtained; and the fifth, ten years after the surgical intervention. In the preoperative assessment, changes were recorded in the myofunctional pattern related to chewing, swallowing, speech and breathing functions. Improvements in the lip, cheek and masseter muscles were reported after SLP therapy, as well as in tongue posture and mandibular range of motion. After 10 years, favorable changes were observed in breathing pattern and tongue posture at rest, organization and stability of speech, articulation, and swallowing patterns, as well as in the patient's self-esteem. Final considerations: the SLP approach associated with orthognathic surgery and orthodontics procedure achieved evolutions and proved to be effective, leading this patient to satisfactory new adjustments of the myofunctional pattern.

Diagnóstico precoz de la estrechez del maxilar superior en la dentición mixta / Early diagnosis of the maxillary´s narrowness in the mixed dentition

Las compresiones del maxilar superior son alteraciones transversales por discrepancia óseo-dentaria. .En la dentición mixta temprana puede establecerse la estrechez mediante índices que relacionan el tamaño dental con el ancho transversal del arco dentario. Se analizaron 33 modelos superiores de niños en el tercer período de desarrollo clínico según Barnett. Se estableció la estrechez realizando el análisis métrico del arco dental mediante el índice de Pont. Se describió la anomalía de posición anterior según las siguientes variables: A) Apiñamiento dentario: 1-Escalón de los dientes anterosuperiores; 2-Rotación mesial de los cuatro incisivos; 3-Rotación mesial de los incisivos centrales y rotación distal de los incisivos laterales y 4-Rotación distal de los incisivos centrales. B) Ausencia de apiñamiento: 1-Reabsorción atípica y 2- Ausencia de reabsorción atípica. Las anomalías de posición y/o reabsorciones atípicas anteriores en este período de desarrollo clínico se asocian a estrechez transversal del maxilar superior Siendo la malposición más frecuente la rotación mesial de los cuatro incisivos, siguiendo las reabsorciones atípicas y el escalón de los dientes anterosuperiores, luego la rotación mesial de los incisivos centrales y distal de los laterales y por último la rotación distal de los incisivos centrales (AU)

Inside the traverse alteration of the maxillary the compressions are described as uni or bilateral where an imbalance is settled down between the dental size and the size of the maxillary causing alterations in the position of the teeth. In the early mixed teething the narrowness of the maxillary can be settled by means of indexes that relate the dental size with the traverse width of the dental arch. Thirty models of the maxillary of children according to Barnett's third development period were analyzed. The metrical analysis of the dental arch form was carried out through Pont's index. The theoretic values were compared with the real ones establishing the deviations of the norm that is to say the narrow nest. Out of the 30 cases analyzed, 40% presented mesial rotation of the 4 incisors; 27% showed a stop of the front teeth; 27% atypical reabsorption; 20% mesial rotation of the central incisors and distal rotation of the lateral incisors and the 10% presented a distal rotation of the central incisors. With regard to the front atypical discrepancy 36.66% of the cases had a discrepancy above 6 mm and the 23.33% below 3 mm (AU)

Características orofaciais de indivíduos com mucopolissacaridoses: um estudo transversal pareado / Orofacial characteristics of individuals with mucopolysaccharidosis: a paired cross-sectional study

As mucopolissacaridoses (MPS) caracterizam-se por um grupo de doenças genéticas metabólicas raras, com manifestações multissistêmicas progressivas. Acarretam diversas alterações físicas, motoras e intelectuais. Dentre as alterações físicas, muitas estão presentes na face e na cavidade bucal. Na área odontológica ainda são poucos os estudos dedicados à MPS, sendo insuficientes as informações sobre as características orofaciais presentes nas pessoas acometidas por essa anomalia. O presente estudo objetivou identificar as características orofaciais de indivíduos com MPS e comparar com um grupo de indivíduos sem MPS. Foi realizado um estudo observacional transversal com uma amostra pareada de 14 indivíduos com MPS e 28 sem MPS, na faixa etária de 5 a 26 anos, pareados por sexo e idade. Os participantes com MPS e sem MPS são atendidos em dois hospitais públicos de Belo Horizonte, região sudeste do Brasil. Em ambos os grupos foi realizada a análise facial e a análise cefalométrica (medidas angulares e lineares). Além disso, também foram identificadas a presença ou ausência de alterações dentárias e maxilomandibulares por meio de radiografias panorâmicas. Previamente ao estudo principal, a examinadora passou pelo processo de calibração prática. Foram obtidos valores kappa entre 0,76 e 0,98. Para as variáveis cefalométricas, não foram observados erros sistemáticos significativos (p> 0,05). Os erros aleatórios para as medidas lineares e angulares foram baixos. A análise estatística entre os grupos foi realizada por meio do teste qui-quadrado e teste t independente. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Minas Gerais. A média de idade dos 42 participantes foi de 13,9 anos (± 7,2). Em relação às alterações faciais e cefalométricas, observou-se que quando comparados com indivíduos sem MPS, a maioria dos indivíduos com MPS apresentou perfil dolicofacial, alteração nas proporções faciais, com aumento da altura facial anterior inferior (AFAI) e incompetência labial (todos p<0,05). Seis medidas angulares foram significativamente maiores entre os indivíduos com MPS: 1s.Na, 1s.NB, FMA, IMPA, AFI e Po.Or_Go.Me; todos p <0,05. Duas medidas angulares apresentaram-se significativamente reduzidas nos indivíduos com MPS: 1s.1i, Ba.N-Ptm.Gn; p <0,05. Quatro medidas lineares apresentaram-se aumentadas entre os indivíduos com MPS: 1s-NA, 1i-NB, S-UL e S-LL; todos p<0,05. E, cinco medidas lineares (PogN-Perp, Co-A, Co-Gn, Nfa-Nfp e overbite; todos p<0,05) apresentaram-se reduzidas entre os indivíduos com MPS. Em relação à presença/ausência de alterações dentárias e maxilomandibulares, observou-se que a presença de dentes supranumerários (p=0,003); dentes conóides (p = 0,009); taurodontismo (p<0,001); dentes impactados (p<0,001); dentes semi-inclusos (p=0,040); dentes inclusos (p=0,013); e dilaceração radicular (p=0,047) foi estatisticamente mais frequente nos indivíduos com MPS quando comparados aos sem MPS. Além disso, a presença de rarefação óssea/ lesão de furca óssea (p=0,032), hipoplasia condilar (p<0,001), lesões ósseas radiolúcidas (p=0,001) e cistos dentígeros (p=0,001) também foram mais frequentes em indivíduos com MPS. Conclui-se que a maioria dos indivíduos com MPS apresentou perfil dolicofacial com aumento da altura facial anteroinferior. Os indivíduos com MPS foram identificados com incisivos superiores e inferiores vestibularizados, espaço nasofaríngeo reduzido e overbite reduzido. A presença de alterações dentárias e maxilomandibulares também foram frequentes nos indivíduos com MPS, ressaltando assim a importância do conhecimento a cerca das manifestações clínicas orais e faciais que podem ser herdadas através da MPS, a fim de se realizar um atendimento odontológico preventivo e eficaz.

Mucopolysaccharidosis (MPS) are characterized as a group of rare metabolic genetic diseases, with progressive multisystemic manifestations. There are several physical, motor and intellectual alterations. Among the physical alterations, many are presented in the face and oral cavity. In the the area of dentistry, there are still few studies dedicated to MPS, with insufficient information about the orofacial characteristics presented in individuals affected by this anomaly. Therefore, the aim of the present study was to evaluate the orofacial features of individuals with Mucopolysaccharidosis (MPS) and to compare the characteristics of those individuals with a group of non-MPS individuals. A cross-sectional study was carried out with a paired sample of 14 MPS individuals and 28 non-MPS individuals between five and 26 years old matched for sex and age. Participants with and without MPS are patients attended at two public hospitals in Belo Horizonte, southeastern region of Brazil. Facial and cephalometric analysis (angular and linear measurements) was performed for both groups. Besides that, the presence/absence of dental and maxillomandibular alterations were assessed through panoramic radiographs. Prior to the main study, the examiner went through practical calibration process. Kappa scores for categorical variables obtained were 0.76 to 0.98. For the cephalometric variables, no systematic errors were observed (p>0.05). Random errors for linear and angular measurements were low. Statistical analysis between groups was performed by means of chi-square test and independent t test. The study was approved by the Research Ethics Committee of the Universidade Federal de Minas Gerais. The mean age of the 42 participants was 13.9 years (±7.2). Regarding facial and cephalometric measures, it was observed that when compared to non-MPS individuals, most MPS individuals were dolichofacial, with facial proportions alterations, increased ALFH, and no passive lip sealing (all p<0.05). Six angular measurements (1s.Na, 1s.NB, FMA, IMPA, AFI, and Po.Or_Go.Me; all p<0.05) were significantly increased among MPS individuals. Two angular measurements (1s.1i, Ba.N-Ptm.Gn; all p<0.05) were significantly decreased among MPS individuals. Four linear measurements were significantly increased among MPS individuals (1s-NA, 1i-NB, S-UL and S-LL; all p<0.05). Five linear measurements (PogN-Perp, Co-A, Co-Gn, Nfa-Nfp and overbite; all p<0.05) were significantly decreased among MPS individuals. It can be concluded that, most MPS individuals were dolichofacial with increased anterior lower facial height. MPS individuals also present pro-inclined upper and lower incisors, reduced nasopharyngeal space and reduced overbite. The presence of dental and maxillomandibular alterations were also more frequent in MPS individuals, highlighting the importance of the knowledge about the oral and facial clinical manifestations that can be inherited with the MPS disease, in order to provide preventive and effective dental care.

Maxillomandibular deformity in a canine with fibrous osteodystrophy secondary to chronic kidney disease

Background: Cases of renal fibrous osteodystrophy are usually associated with nutritional causes, which of renal causesare considered uncommon in dogs. This disorder is characterized by the intense proliferation of fibrous connective tissue inbones, impairing bone stiffness. The aim of this study was to report a case of fibrous osteodystrophy secondary to chronickidney disease in a canine with a “rubber jaw” facial deformity.Case: A 4-year-old male unneutered mongrel dog weighing 5.2 kg had a history of apathy, progressive weight loss andvomiting for one month, and polyuria and polydipsia for more than three months. In addition, the owner complained aboutthe deformed appearance in the muzzle region of the animal, which was evidenced flexibility of the same, with a displacement of the mandible and maxilla on physical examination, similar to the “rubber jaw”. Blood tests revealed macrocyticanemia, elevated total plasma proteins, and lymphopenia-associated neutrophilia, as well as hyperphosphatemia (24 mg/dL), uremia (283.6 mg/dL) and increased creatinine (8.6 mg/dL), ALT (143.2 UI/L) and alkaline phosphatase (3222.2UI/L), while calcium (8.8 mg/dL) and albumin (1.9 g/dL) were decreased. A serological test for visceral leishmaniasis wasalso performed, which was negative. Abdominal ultrasound imaging revealed kidneys with alterations in tissue architecture, increased thickness and complete loss of cortico-medullary relationship, while the parathyroid gland was enlargedand spindle-shaped. Cranial radiography showed marked radiopacity of the bilateral maxillary bones, with destructionof the nasal, turbinate and frontal bones, as well as loosening of the teeth and destruction of the mandibular bone matrix,characterizing an aspect of “rubber jaw”. Based on the history, history and evidence of azotemia, hyperphosphatemia andloss of facial bone density, the diagnosis of fibrous osteodystrophy secondary to chronic kidney...(AU)

Myosin 1H and the soft tissue profile of african american females with mandibular prognathism

Introduction: The aim of this study was to explore the influence of Myosin 1H on the soft tissue profile of African American females. Methods: Fourteen African American females from the University of Pittsburgh School of Dental Medicine Dental Registry and DNA Repository with the ancestral genotype GG, marker rs10850110, locus 12q24.11 were analyzed. For this investigation, measurements were taken of the eleven items that comprise the Holdaway soft tissue analysis. Profile differences between ethnicity and corresponding normative values were explored by independent-sample t tests for all facial profile measurements. Student's t test for independent means was used to determine differences with accepted norms. Significance was set a p<0.05. Results: There were significant differences between four of the eleven Holdaway values and the reported values for African Americans. The mean convexity value of the African American female group was 1.0 mm less the normative value of 5.7 mm (p>0.000). In contrast, the H angle of the African American females was larger than the normative value. Conclusions: Our study confirms previous research that Myosin 1H contributes to mandibular prognathism. It agrees with the idea that Myosin 1H is less influential in the maxillary soft tissue complex. Understanding the genetic influence of soft tissue growth would allow improved therapies and prevention approaches.

Introduçâo: O objetivo desse estudo foi determinar a influência da miosina 1H nos tecidos moles de mulheres americanas negras. Métodos: Foram estudadas quatorze mulheres americanas negras participantes do projeto Dental Registry and DNA Repository da Faculdade de Odontologia da Universidade de Pittsburgh com o genótipo comum GG do marcador rs10850110, localizado no lócus 12q24.11. Medidas de onze parâmetros que compõem a análise de tecidos moles de Holdaway foram utilizadas. Diferenças entre etnicidade e medidas normais correspondentes, foram exploradas através do teste t de Student de amostras independentes para todas as medidas faciais. O teste t de Student para médias independentes foi usado para determinar diferenças em comparação à medidas normais. A significância foi estabelecida em p<0,05. Resultados: Houve uma diferença estatisticamente significante entre quatro das onze medidas de Holdaway. A convexidade média da mulher americana negra foi de 1,0 mm a menos que o valor normal de 5.7 mm (p>0.000). Em contraste, o ângulo H das mulheres americanas negras foi maior que o valor normal. Conclusões: O nosso estudo confirma resultados anteriores que a miosina 1H contribui para o prognatismo mandibular. Nossos resultados concordam com a ideia de que a miosina 1H tem menor influência nos tecidos moles da maxila. Entender a influência genética no crescimento dos tecidos moles irá possivelmente permitir melhorar as abordagens de tratamento e prevenção atuais.
