ABSTRACT
A adoção da chupeta e mamadeira pelos pais podem trazer problemas no desenvolvimento craniofacial da criança. A sucção digital é outro fator influenciador da má formação da face, este pode ser antecedido pela mamadeira e chupeta. O conhecimento sobre o desenvolvimento facial correto ajuda no reconhecimento de desvios da normalidade. Foi realizada uma revisão da literatura a fim de analisar e comparar os efeitos no crescimento facial entre os hábitos deletérios e a amamentação fisiológica. Muitos registros de malformações causadas por hábitos deletérios foram encontrados. Conclui-se que a amamentação natural ainda é a melhor forma de alimentação para crianças, e nenhuma outra opção será melhor que a fisiológica, sendo aconselhável evitar o uso dos demais(AU)
The adoption of pacifiers and bottles by parents can bring problems in the child's craniofacial development. Finger sucking is another factor influencing the malformation of the face, which can be preceded by the bottle and pacifier. Knowledge about correct facial development helps in recognizing deviations from normality. A literature review was carried out in order to analyze and compare the effects on facial growth between harmful habits and physiological breastfeeding. Many records of malformations caused by deleterious habits were found. It is concluded that natural breastfeeding is still the best form of feeding for children, and no other option will be better than the physiological one, being advisable to avoid the use of the others(AU)

Introdução: O aumento da expectativa média de vida leva a população a buscar, com maior frequência, tratamentos estéticos que visem o rejuvenescimento da face e do pescoço. O Ultrassom microfocado (MFU) é descrito como uma opção de tratamento não-invasiva para a flacidez facial e o envelhecimento. Objetivo: Revisar a literatura científica quanto ao uso do MFU no processo de rejuvenescimento facial e correção da flacidez da pele. Metodologia: Trata-se de uma revisão narrativa da literatura, baseada na pesquisa de artigos científicos nas bases de dados PubMed e Biblioteca Virtual em Saúde realizada durante o mês de março de 2022, através da seguinte estratégia de busca: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". Um total de 19 manuscritos foram incluídos em síntese qualitativa. Desenvolvimento: O MFU pode ser aplicado no tecido subcutâneo, produzindo pequenos pontos de coagulação térmica dentro da camada reticular média a profunda da derme e subderme. A aplicação de calor nesses discretos pontos de coagulação térmica faz com que haja neossíntese de colágeno e consequente enrijecimento da pele. Estudos recentes evidenciaramresultados promissores quanto a aplicação do MFU em regiões de sulco nasolabial, linha da mandíbula, sobrancelhas, região infraorbital, palpebra inferior e ligamentos de retenção zigomático-bucais. Considerações finais: O MFU tem se mostrado uma técnica segura, sendo considerado eficaz, não-invasiva, bem tolerada pelos pacientes e viável para a prática clínica médica e odontológica.
Introduction: The increase in average life expectancy leads the population to seek, with greater frequency, aesthetic treatments aimed at rejuvenating the face and neck. Microfocused ultrasound (MFU) is described as a non-invasive treatment option for facial sagging and aging. Objective: To review the scientific literature regarding the use of MFU in the process of facial rejuvenation and correction of sagging skin. Methodology: This is a narrative review of the literature, based on the search for scientific articles in the PubMed and Virtual Health Library databases carried out during the month of March 2022, using the following search strategy: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". A total of 19 manuscripts were included in a qualitative synthesis. Development: MFU can be applied to the subcutaneous tissue, producing small points of thermal coagulation within the middle to deep reticular layer of the dermis and subdermis. The application of heat to these discrete points of thermal coagulation causes collagen neosynthesis and consequent skin tightening. Recent studies have shown promising results regarding the application of MFU in regions of the nasolabial sulcus, jaw line, eyebrows, infraorbital region, lower eyelid and zygomatic-buccal retention ligaments. Final considerations: MFU has been shown to be a safe technique, being considered effective, non-invasive, well tolerated by patients and viable for clinical medical and dental practice.

As exostoses mais conhecidas são o Torus palatino e mandibular, que se desenvolvem a partir do crescimento benigno da cortical óssea, localizadas respectivamente na linha média palatina e superfície lingual de caninos e pré-molares, podendo ser unilaterais ou bilaterais. Esse trabalho tem como objetivo o estudo de um grupo familiar que apresentaram o Torus como característica em comum, buscando confirmar a presença e prevalência das características clínicas multifatoriais listadas na literatura, possibilitando o diagnóstico da etiologia e assim traçando um plano de tratamento individual, se necessário. Como metodologia, foi realizada uma triagem com cada membro familiar na clínica Odontológica da Faculdade Sete Lagoas - FACSETE, descartando a participação no estudo os membros que não apresentaram o Torus. Os indivíduos que apresentaram indicação da remoção cirúrgica foram encaminhados para clínica de cirurgia da própria instituição. Concluímos, portanto, com este estudo que fatores genéticos e ambientais colaboram como fator etiológico mais predominantes para surgimento do Torus no grupo familiar estudado... (AU)
The best known exostosis are the palatine and mandibular Torus, which develop from the benign growth of the cortical bone, located respectively in the midpalatal line and lingual surface of canines and premolars, and maybe unilateral or bilateral. This work aims to study a family group that had Torus as a common feature, confirming the presence and prevalence of multifactorial clinical features listed in the literature, enabling the diagnosis of etiology and thus outlining an in dividual treatment plan, if necessary.

Aim: This study aimed to evaluate the correlation between vertical dimension of occlusion (VDO) and various facial measurements in a sample of Sudanese adults. Material and Methods: A total of 113 dental students (33 males and 80 females) with a mean age of 21.7±1.26 years were enrolled in this study. Different facial measurements including (Eye-Mouth, Eye-Eye, Eye-Ear, and Ear Height) were compared with two different measurements of VDO: N-Gn (from the tip of the nose to the tip of the chin), and Sn-Me (from the base of the nose to the bottom of the chin). Pearson's correlation coefficient test was utilized for the correlation between the measured parameters. A p-value of less than 0.05 was considered significant for all analyses. Results: A significant positive correlation was shown between all measured facial distances and both measured VDO distances. Though, the strongest correlation was seen for the eye-mouth distance (r= 0.725, p<0.001), while the weakest was for ear height (r= 0.254, p= 0.007). A paired t-test revealed a significant longer N-Gn distance than Sn-Me distance. Also, it has been shown that there were no significant differences between right and left sides of the face. Conclusion: The distance measured from the outer canthus of the eye to the angle of the mouth can be used to predict Subnasale-Menton (Sn-Me) distance.
Objetivo: Este estudio tuvo como objetivo evaluar la correlación entre dimensión vertical oclusal (DVO) y varias medidas faciales en una muestra de adultos sudaneses. Material y Métodos: Un total de 113 estudiantes de odontología (33 hombres y 80 mujeres) con una edad media de 21,7 ± 1,26 años se inscribieron en este estudio. Se compararon diferentes medidas faciales que incluyen (ojo- boca, ojo-ojo, ojo-oído y altura de la oreja) con dos medidas diferentes de DVO: N-Gn (desde la punta de la nariz hasta la punta del mentón) y Sn -Yo (desde la base de la nariz hasta la parte inferior del mentón). Se utilizó la prueba del coeficiente de correlación de Pearson para la correlación entre los parámetros medidos. Un valor de p inferior a 0,05 se consideró significativo para todos los análisis. Resultados: Se mostró una correlación positiva significativa entre todas las distancias faciales medidas y ambas distancias DVO medidas. Sin embargo, la correlación más fuerte se observó para la distancia ojo-boca (r=0,725, p<0,001), mientras que la más débil fue para la altura de las orejas (r=0,254, p=0,007). Una prueba de t pareada reveló una distancia N-Gn significativamente más larga que la distancia subnasal-mentón. Además, se ha demostrado que no hubo diferencias significativas entre los lados derecho e izquierdo de la cara. Conclusión: La distancia medida desde el canto externo del ojo hasta el ángulo de la boca puede utilizarse para predecir la distancia subnasal-mentón.

Introdução: A respiração oral é uma alteração prevalente na infância, que tem como uma das consequências a alteração na musculatura dos lábios. A termografia infravermelha, é uma opção para se avaliar a população infantil, pois não gera incômodo, é segura e não emite radiação. Acredita-se que a termografia da face e dos lábios possa auxiliar no diagnóstico e acompanhamento fonoaudiológico. Objetivo: 1) descrever a distribuição de temperatura na face de crianças respiradoras nasais; 2) verificar se os pontos termoanatômicos descritos para adultos pela literatura são facilmente visualizados nas crianças; 3) comparar os resultados da temperatura média dos pontos termoanatômicos da face entre os sexos; e 4) comparar a temperatura dos pontos termoanatômicos e áreas do lábio superior e lábio inferior entre crianças respiradoras orais e nasais. Métodos: estudo observacional transversal realizado com 30 crianças respiradoras nasais e 30 orais de quatro a 11 anos, de ambos os sexos. Utilizou-se a termografia infravermelha da face para obter um termograma frontal, um de perfil direito e outro esquerdo de cada participante. Foram marcados 14 pontos termoanatômicos no termograma frontal e 6 em cada de perfil, mais as áreas de lábio superior e inferior. Foi realizada análise qualitativa visual das imagens, além de análise descritiva e cálculo do ∆T (diferença entre os dois lados da face). Também foi realizada análise de concordância intra e interavaliadores na avaliação dos pontos utilizando-se o Coeficiente de correlação intraclasse. Comparou-se as temperaturas entre os sexos de respiradores nasais, temperatura de respiradores orais e nasais por meio dos Testes T e Mann Whitney. Além disso, comparou-se a diferença entre a temperatura da área de lábio superior e inferior (∆T área) e dos pontos localizados no lábio superior com os do inferior (∆T pontos) entre respiradores orais e nasais utilizando-se os mesmos testes. Resultados: As maiores temperaturas foram no ponto Comissura Palpebral Medial na vista frontal e no ponto Temporal de perfil. O ponto supratroclear não é um ponto que se destaca na face das crianças. O ∆T foi maior que 0,3 para a maioria dos pontos. As regiões hiperradiantes foram testa, olhos e região perioral e as hiporradiantes nariz, bochechas e região do mento. A análise de concordância intra e interavaliadores na avaliação dos pontos variou de boa a ótima. Não foi encontrada diferença de temperatura entre os sexos. Verificou-se que os pontos termoanatômicos mais próximos ao lábio, áreas dos lábios e meato acústico externo apresentaram temperatura menor nos respiradores orais do que nos nasais. Não houve diferença entre os grupos no ∆T de área e pontos. Conclusão: as crianças respiradoras nasais apresentaram como regiões hiperradiantes a testa, os olhos e a região perioral. Os pontos termoanatômicos encontrados nas crianças, são coincidentes com os da população adulta, exceto o ponto Supratroclear, que não é nítido. Os respiradores nasais apresentaram assimetria térmica e não houve diferença entre os sexos. Crianças respiradoras orais apresentaram menor temperatura na região dos lábios e do meato acústico externo do que as respiradoras nasais e não houve diferença entre lábio superior e inferior.
Introduction: mouth breathing is a prevalent disorder in childhood, which has as consequence alteration in the muscle of the lips. Infrared thermography, is an interesting option to assess the child population, as it is safe and does not cause discomfort nor emit radiation. It is believed that thermography of the face and lips can help in the orofacial myology diagnosis and follow-up. Objective: 1) to describe the facial spatial temperature distribution of nose breathing children; 2) verify if the thermoanatomical points described for adults in the literature are easily viewed in nose breathing children; 3) to compare the results of the mean temperature of the thermoanatomical points of the face of nose breathing children between sexes; 4) to compare the temperature of the thermoanatomical points and areas of lips between mouth and nose breathing children. Methods: Cross-sectional observational study of 30 nose-breathing and 30 mouth breathing children of both sexes aged 4 to 11 years. Front view, right side view, and left side view thermogram of each participant were recorded. The mean temperatures of 14 anatomical thermal points in the front view thermogram and 12 points in the side view and lip areas were assessed. A visual qualitative analysis of the images was performed, in addition to a descriptive analysis, and calculation of the ∆T (difference between the two sides of the face). Intra- and interrater agreement analyses of point assessment were made using the intraclass correlation coefficient. Temperatures were compared between sexes of nasal breathers, and temperatures of nose and mouth breathers using the T and Mann Whitney tests. In addition, the difference between the temperature of the upper and lower lip area (∆T area) and between the points located on the upper lip with those on the lower lip (∆T points) of mouth and nose breathers were compared using the same tests. Results: Medial Palpebral Commissure point had the highest temperature in the front view thermogram and Temporal point in the side view. The Supratrochlear point is not a point that stands out on the face of children. ∆T was greater than 0.3 for most points. The warmest regions were forehead, eyes and perioral region and the coldest, nose, cheeks and chin region. The analysis of intra- and inter-rater agreement in the assessment of points ranged from good to excellent. No temperature difference was found between the sexes. It was found that the thermoanatomical points closest to the lip, areas of the lips and External Acoustic Meatus presented lower temperature in mouth breathers than in nose ones. There was no difference between the groups in ∆T area and points. Conclusion: nose breathing children presented the forehead, eyes and perioral region as the hottest regions. The thermoanatomical points found in children are similar to those on the adult population, except for the Supratrochlear point, which does not stand out. Nose breathers showed thermal asymmetry and there was no difference between the sexes. Mouth breathing children have lower temperature in the region of the lips than nose breathing children.

This paper reviews some recent studies on the recognition and evaluation of facial paralysis based on artificial intelligence. The research methods can be divided into two categories: facial paralysis evaluation based on artificial selection of patients' facial image eigenvalues and facial paralysis evaluation based on neural network and patients' facial images. The analysis shows that the method of manual selection of eigenvalues is suitable for small sample size, but the classification effect of adjacent ratings of facial paralysis needs to be further optimized. The neural network method can distinguish the neighboring grades of facial paralysis relatively well, but it has a higher requirement for sample size. Both of the two methods have good prospects. The features that are more closely related to the evaluation scale are selected manually, and the common development direction may be to extract the time-domain features, so as to achieve the purpose of improving the evaluation accuracy of facial paralysis.

OBJECTIVE@#To explore the genetic basis for two Chinese pedigrees affected with Coffin-Siris syndrome (CSS).@*METHODS@#Whole exome sequencing (WES) was carried out for the probands. Candidate variants were verified by Sanger sequencing of the probands and their family members.@*RESULTS@#The two probands were respectively found to harbor a heterozygous c.5467delG (p.Gly1823fs) variant and a heterozygous c.5584delA (p.Lys1862fs) variant of the ARID1B gene, which were both of de novo in origin and unreported previously. Based on the guidelines of American College of Medical Genetics and Genomics, both variants were predicted to be pathogenic (PVS1+PS2+PM2).@*CONCLUSION@#The c.5467delG (p.Gly1823fs) and c.5545delA (p.Lys1849fs) variants of the ARID1B genes probably underlay the CSS in the two probands. Above results have enabled genetic counselling and prenatal diagnosis for the pedigrees.

Objective: To assess the taste function of healthy Chinese adults with the reliable whole-mouth taste test, and to analyze the correlation of taste function with age and gender. Methods: The clinical data of 584 participants reporting the normal sense of smell and taste from March 2019 to January 2020 in the Physical Examination Center of Beijing Anzhen Hospital were analyzed in the study, including 297 males and 287 females, aging (46.9±16.6) years. The subjects were divided into youth group (19-35 years old), middle aged group (36-50 years old), middle-elderly aged group (51-65 years old) and elderly group (66-80 years old). The taste test involved 5 tastants (sour, sweet, salty, umami and bitter) and 7 concentrations. The perception and recognition scores of five tastes were obtained through the whole-mouth taste test. SPSS 22.0 software was used for statistical analysis. Results: The intra-class correlation coefficients of the whole-mouth taste test were 0.751 to 0.828, which showed high test-retest reliability. The total score of perception and recognition of five tastes showed the significant negative correlation with age (r value was -0.49 and -0.44, respectively, both P<0.001). Compared with the other two groups, taste function of middle-elderly aged and elderly group decreased significantly (all P<0.001). There was no significant difference in total perception scores and total recognition scores between youth and middle aged group (all P>0.05). The perception scores and recognition scores of sour, salty, umami, bitter and total scores in females were higher than those in males (all P<0.05), but there was no significant difference in perception scores and recognition scores for sweet between them (P value was 0.584 and 0.223, respectively). Conclusions: The taste function is significantly negatively correlated with age. Except the sweet, females are more sensitive to the sour, salty, umami and bitter tastes than males.

OBJECTIVE@#To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema.@*METHODS@#A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up.@*RESULTS@#After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average.@*CONCLUSION@#585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

OBJECTIVE@#To establish a deep learning algorithm that can accurately determine three-dimensional facial anatomical landmarks, multi-view stacked hourglass convolutional neural networks (MSH-CNN) and to construct three-dimensional facial midsagittal plane automatically based on MSH-CNN and weighted Procrustes analysis algorithm.@*METHODS@#One hundred subjects with no obvious facial deformity were collected in our oral clinic. Three-dimensional facial data were scanned by three-dimensional facial scanner. Experts annotated twenty-one facial landmarks and midsagittal plane of each data. Eighty three-dimensional facial data were used as training set, to train the MSH-CNN in this study. The overview of MSH-CNN network architecture contained multi-view rendering and training the MSH-CNN network. The three-dimensional facial data were rendered from ninety-six views that were fed to MSH-CNN and the output was one heatmap per landmark. The result of the twenty-one landmarks was accurately placed on the three-dimensional facial data after a three-dimensional view ray voting process. The remaining twenty three-dimensional facial data were used as test set. The trained MSH-CNN automatically determined twenty-one three-dimensional facial anatomical landmarks of each case of data, and calculated the distance between each MSH-CNN landmark and the expert landmark, which was defined as position error. The midsagittal plane of the twenty subjects' could be automatically constructed, using the MSH-CNN and Procrustes analysis algorithm. To evaluate the effect of midsagittal plane by automatic method, the angle between the midsagittal plane constructed by the automatic method and the expert annotated plane was calculated, which was defined as angle error.@*RESULTS@#For twenty subjects with no obvious facial deformity, the average angle error of the midsagittal plane constructed by MSH-CNN and weighted Procrustes analysis algorithm was 0.73°±0.50°, in which the average position error of the twenty-one facial landmarks automatically determined by MSH-CNN was (1.13±0.24) mm, the maximum position error of the orbital area was (1.31±0.54) mm, and the minimum position error of the nasal area was (0.79±0.36) mm.@*CONCLUSION@#This research combines deep learning algorithms and Procrustes analysis algorithms to realize the fully automated construction of the three-dimensional midsagittal plane, which initially achieves the construction effect of clinical experts. The obtained results constituted the basis for the independent intellectual property software development.

Objective: To explore the establishment of an efficient and automatic method to determine anatomical landmarks in three-dimensional (3D) facial data, and to evaluate the effectiveness of this method in determining landmarks. Methods: A total of 30 male patients with tooth defect or dentition defect (with good facial symmetry) who visited the Department of Prosthodontics, Peking University School and Hospital of Stomatology from June to August 2021 were selected, and these participants' age was between 18-45 years. 3D facial data of patients was collected and the size normalization and overlap alignment were performed based on the Procrustes analysis algorithm. A 3D face average model was built in Geomagic Studio 2013 software, and a 3D face template was built through parametric processing. MeshLab 2020 software was used to determine the serial number information of 32 facial anatomical landmarks (10 midline landmarks and 22 bilateral landmarks). Five male patients with no mandibular deviation and 5 with mild mandibular deviation were selected from the Department of Orthodontics or Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from June to August 2021. 3D facial data of patients was collected as test data. Based on the 3D face template and the serial number information of the facial anatomical landmarks, the coordinates of 32 facial anatomical landmarks on the test data were automatically determined with the help of the MeshMonk non-rigid registration algorithm program, as the data for the template method to determine the landmarks. The positions of 32 facial anatomical landmarks on the test data were manually determined by the same attending physician, and the coordinates of the landmarks were recorded as the data for determining landmarks by the expert method. Calculated the distance value of the coordinates of facial anatomical landmarks between the template method and the expert method, as the landmark localization error, and evaluated the effect of the template method in determining the landmarks. Results: For 5 patients with no mandibular deviation, the landmark localization error of all facial anatomical landmarks by template method was (1.65±1.19) mm, the landmark localization error of the midline facial anatomical landmarks was (1.19±0.45) mm, the landmark localization error of bilateral facial anatomical landmarks was (1.85±1.33) mm. For 5 patients with mild mandibular deviation, the landmark localization error of all facial anatomical landmarks by template method was (2.55±2.22) mm, the landmark localization error of the midline facial anatomical landmarks was (1.85±1.13) mm, the landmark localization error of bilateral facial anatomical landmarks was (2.87±2.45) mm. Conclusions: The automatic determination method of facial anatomical landmarks proposed in this study has certain feasibility, and the determination effect of midline facial anatomical landmarks is better than that of bilateral facial anatomical landmarks. The effect of determining facial anatomical landmarks in patients without mandibular deviation is better than that in patients with mild mandibular deviation.

Desde la antigüedad la belleza y la armonía facial han sido objetivos que tanto pintores como escultores, médicos y las personas tratan de lograr. Los rostros han sido estereotipados y es así como las caras proporcionadas tanto en alto como en ancho con perfiles que son rectos o levemente convexos son los que se asocian a bondad, generosidad, personas con luz interior, princesas y son las "buenas de las películas". Pero ¿qué sucede con aquellos rostros cóncavos, con tercios inferiores ya largos o cortos? a ellos les ha tocado la peor parte, son los malos, los oscuros, los "villanos de las películas". Objetivos La finalidad de este trabajo es acercar a los colegas ortodoncistas una opción de tratamiento en clase III esqueletal, cuando el camuflaje ortodóncico no alcanza para resolver el crecimiento alterado entre el maxilar superior y el maxilar inferior (AU)
Beauty and facial harmony have been, since the beginning of humanity, a target for artists, painters, sculptores, and even people and doctors to accomplish. There is a stereotype of beauty: faces with proportional dimensions both in height and length, with straight profiles or somehow convex are associated with kindness, generosity and inner beauty. We can see this in movies where the heroes, the princesses, the "good guys" are portrayed with these types of faces. And what happens with people with concave faces, long or short inferior thirds? They are doomed to be the evil, the dark and "the villains" (AU)

Este trabajo tuvo como objetivo evaluar características de la sonrisa en pacientes con necesidad de tratamiento ortodóntico. Como objetivos específicos, se planteó estudiar el arco de la sonrisa, la línea del labio superior y los corredores bucales, que son tres componentes importantes a la hora de elaborar un plan de tratamiento adecuado para devolver al paciente una sonrisa funcional y estéticamente aceptable. La muestra quedó conformada por 157 pacientes; de cada uno de ellos se obtuvo una foto de una sonrisa voluntaria. Se encontró que el arco de la sonrisa, en el 39,5 %, presentaba un arco consonante; un 20,4 %, uno plano y el 40,1 % restante, uno no consonante. Al estudiar la línea del labio superior, se observó que, en el 8,3 %, la línea era baja; en el 62,4 %, media y en el 29,3 %, alta. En cuanto a los corredores bucales, se observó que el valor medio, en proporción a la distancia intercomisural del corredor bucal total, era de 15,89 % ± desvío estándar (5,03 %); el valor total máximo, 26,19 % y el valor mínimo, 2,74 %. Conociendo la prevalencia de cada uno de estos datos, se podrá arribar al diagnóstico y posterior plan de tratamiento para cada paciente de manera individualizada(AU)
This work aimed at evaluating smile characteristics in patients in need of orthodontic treatment. As specific objectives, it was raised the issue of studying the smile arch, upper lip line and buccal corridors, which are three important components when preparing an adequate treatment plan to restore the patient a functional and aesthetically acceptable smile. The sample consisted of 157 patients and a photo of a voluntary smile was obtained from each of them. It was found that the smile arch had a consonant arch in 39.5%, 20.4% a flat arch and the remaining 40.1% a nonconsonant arch. When studying the upper lip line, it was observed that in 8.3% the line was low, 62.4% medium and 29.3% high. As regards the buccal corridors, it was observed that the mean value in proportion to the intercommissural distance of the total buccal corridor was 15.89% ± standard deviation (5.03%); maximum total value was 26.19% and minimum value 2.74%. Knowing about the prevalence of each of these data, it will be able to arrive at the diagnosis and subsequent treatment plan for each patient individually(AU)

INTRODUCTION. A patient at a critical situation has a higher risk of pressure injuries, and their incidence in intensive care continues being high and variable, despite its prevention. In Ecuador the reality of this complication is unknown. OBJECTIVE. To perform a demographic and epidemiological characterization of critically ill patients with pressure injuries. MATERIALS AND METHODS. Descriptive, retrospective study. From a population of 2 087 admitted to the Adult Unit Intensive Care Area of the Carlos Andrade Marín Specialties Hospital, demographic and epidemiological data were collected from 147 records of physical and electronic Medical Records of patients who pressure injuries, in the period January 1 to December 31, 2018. The data were analyzed in the statistical program International Business Machines Statistical Package for the Social Sciences, version 22. RESULTS. Median age was 66 years; male sex 63,3%, pre-obese 40,8%, hypertensive 37,6% and diabetic 23,8%. More than 60,0% received invasive mechanical ventilation, sedatives and vasoactive drugs, the median of the Acute Physiology and Chronic Health disease Classification System II was 20 (IQ 14-27), mortality 34,0%. The prevalence of pressure injuries was 7,0% and incidence 3,49%. The location of pressure injuries were: the sacral region 62,6%, heel 24,0% and face 7,5%; 59,2% stage 2 and 5,4% stage 3.

SUMMARY: The aim of this study was to examine the localization of the landmarks in the maxillofacial region and their relations with each other and to evaluate them morphologically and clinically. Our study included 41 dry adult human skulls of unknown age and sex of Anatolian population. Statistical analysis of the data obtained in our study was performed with SPSS v.20.0 software (IBM Corp., Armonk, NY, USA). Statistical significance was accepted as P ? 0.05. Whereas the mean right supraorbital depth (SOD) value was significantly greater than the mean left SOD value (p 0.05). Correlation values in our study varied between -0.156 and 0.612. The highest correlation value was obtained in the positive direction between the orbital height (OH) and supraorbital foramen-infraorbital foramen (SOF-IOF) measurements (r = 0.612, p < 0.001). We believe that measurements of the orbit, SOF, and IOF and our data on their localizations, along with the relationships that we observed in our study will allow surgeons to avoid damaging the neurovascular bundles during surgical interventions and local anesthesia procedures in the frontal, periorbital, and maxillofacial regions.
RESUMEN: El objetivo de este estudio fue examinar la localización de los hitos en la región maxilofacial y sus relaciones entre sí y evaluarlos morfológica y clínicamente. Nuestro estudio incluyó 41 cráneos humanos adultos secos de edad y sexo desconocidos de la población de Anatolia. El análisis estadístico de los datos obtenidos en nuestro estudio se realizó con el software SPSS v.20.0 (IBM Corp., Armonk, NY, EE. UU.). La significación estadística se aceptó como P ? 0,05. Mientras que el valor medio de la profundidad supraorbitaria derecha (SOD) fue significativamente mayor que el valor medio de la SOD izquierda (p 0,05). Los valores de correlación en nuestro estudio variaron entre -0,156 y 0,612. El mayor valor de correlación se obtuvo en la dirección positiva entre las medidas de altura orbitaria (OH) y foramen supraorbitario-foramen infraorbitario (SOF-IOF) (r = 0,612, p <0,001). Creemos que las mediciones de la órbita, SOF e IOF y nuestros datos sobre sus localizaciones, junto con las relaciones que observamos en nuestro estudio, permitirán a los cirujanos evitar dañar los haces neurovasculares durante las intervenciones quirúrgicas y los procedimientos de anestesia local en la zona frontal, periorbitaria. y regiones maxilofaciales.
