Aesthetic effect evaluation of the xenogeneic collagen matrix in keratinized mucosa augmentation around dental implants / 口腔疾病防治

Objective@#To evaluate the stability and aesthetic effect of a xenogeneic collagen matrix (mucograft) on achieving an adequate keratinized mucosa width (KMW) around implants and to provide a reference basis for the clinical application of xenogeneic collagen matrix materials.@*Methods@#The hospital ethics committee approved the study protocol, and the patients provided informed consent. Twenty patients with a KMW<2 mm at the buccal implant site who were treated in Binzhou Medical University Affiliated Yantai Stomatological Hospital from July 2020 to September 2022 were included, and a total of 36 implants were included. The mean age of the patients was (52.0±10.4) years, of which 18 were females and 2 were males. They were divided into a free gingival graft group (FGG, control group) and a xenogeneic collagen matrix group (test group) according to different graft materials. The incremental effect of the KMW on the buccal side of the implant and the mucosal shrinkage rate was measured at 1 month and 3 months after the operation. The mucosal scar index (MSI) was evaluated after the operation.@*Results@#At 3 months postoperatively, the KMW was (3.67 ± 1.06) mm in the control group and (2.96 ± 0.98) mm in the test group, and the difference was statistically significant (t = 2.076, P<0.05). The KMW shrinkage rate was (33.34 ± 16.30) % in the test group and (22.05 ± 15.47) % in the control group at 1 month postoperatively and (51.95 ± 12.60) % in the test group and (37.44 ± 16.30) % in the control group at 3 months postoperatively, with statistically significant differences between the two groups at the same time points (P<0.05). Three months after surgery, the test group showed significantly better outcomes than the control group in terms of the five scar indicators (scar width, scar convexity, scar color, scar trace, and overall appearance), and the difference was statistically significant (P<0.05).@*Conclusion@#Xenogeneic collagen matrix can increase the peri-implant KMW and achieve a more natural and coordinated soft tissue aesthetic effect but with a higher shrinkage rate.

Clinical application of lithium disilicate glass ceramic cantilever resin-bonded fixed partial denture in the restoration of single anterior tooth loss / 口腔疾病防治

Objective@#To investigate the clinical effect of lithium disilicate glass ceramic cantilever resin-bonded fixed partial dentures (CRBFPDs) on single anterior tooth loss to provide a reference for the selection of restoration methods for single anterior tooth loss.@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-two patients with less than two anterior teeth with monomaxillary loss were included in this study. After 6 months, 1 year, 2 years, and 3 years, the aesthetic and functional effects of the restorations and the periodontal health status were evaluated, and the visual analog scale (VAS) was used to assess patient satisfaction.@*Results@#During the observation period, the connector fractured in one case within 3 months. One case had debonded within 2 years. The aesthetic restoration effect of all lithium disilicate glass ceramic CRBFPDs was categorized as Class A. The periodontal health was good, there was no clinical absorption in the soft and hard tissues of the abutment or subbridge, periodontal status according to the evaluation indices was classified as class A, and the total satisfaction rate of the patient was 100%.@*Conclusion@#For single anterior tooth loss patients, lithium disilicate glass ceramic cantilever resin-bonded fixed partial denture can achieve the restoration effect of less invasion, better adhesion, aesthetics, comfort and good biocompatibility. With high patient satisfaction, it can be considered an ideal restoration method for replacing a single anterior tooth.

Marco legal para la prevención de procedimientos estéticos con sustancias modelantes / Legal framework for preventing aesthetic procedures with modeling substances i:en

En la actualidad, la alogenosis iatrogénica es una condición reconocida en todo el orbe, especialmente en Latinoamérica, donde es evidente la ausencia de control en la administración de sustancias no reguladas con fines estéticos, lo que ha devenido un problema emergente por la magnitud de las complicaciones, ya que algunos productos, como aceites minerales, hidrocarburos, silicona industrial, generan graves consecuencias, tanto locales como sistémicas, en el organismo. Muchos países aún no han regulado la prohibición de esta práctica, aunque cada día son más las campañas para prevenirla; sin embargo, al mismo tiempo aumenta la incidencia de la enfermedad en todo el mundo por el incremento de estos procedimientos estéticos. Al respecto, en Cuba, el creciente número de afectados por esta causa evidencia vulnerabilidad en el cumplimiento de lo establecido hasta la fecha, por lo que se impone instaurar un marco legal de estricto cumplimiento que regule la inyección de sustancias modelantes con fines estéticos.

Currently, iatrogenic allogenosis is a condition recognized throughout the world, especially in Latin America, where the absence of control in the administration of unregulated substances for aesthetic purposes is evident, which has become an emerging problem due to the magnitude of complications, since some products, such as mineral oils, hydrocarbons, industrial silicone, generate serious consequences, both local and systemic, in the body. Many countries have not yet regulated the prohibition of this practice, although every day there are more campaigns to prevent it. However, at the same time the incidence of the disease increases worldwide due to the increase in these aesthetic procedures. In this regard, in Cuba, the growing number of people affected by this cause shows vulnerability in compliance with what has been established to date, that is why it is necessary to establish a legal framework of strict compliance that regulates the injection of modeling substances for aesthetic purposes.

Ética, ecología y ecosofía: perspectivas divergentes para refundamentar la bioética global

el texto busca ampliar las fronteras del concepto de "bioética global", centro de la propuesta teórica de Van Rensselaer Potter sobre la "bioética ecológica" en su obra Global Bioethics, de cara a la "ética de la tierra" desarrollada por el ecólogo y ambientalista Aldo Leopold y el análisis de la "ecosofía" planteado por el filósofo y psicoanalista Félix Guattari en Las tres ecologías. Dicha caracterización se plantea con el fin de establecer presupuestos teóricos en torno a las nociones de bioética ecológica y ecosofía en la perspectiva de la bioética global en un renovado intento de ampliación de sus horizontes disciplinares. Se establecen tres momentos para el análisis: inicialmente se caracteriza la ética de la tierra propuesta por Arnold Leopold en su obra A Sand County Almanach. Posteriormente, se analizan los principales aspectos de la "ética ecológica" en la obra Global Bioethics. Finalmente, se destacan varios aspectos de la ecosofía de Félix Guattari que ponen en perspectiva el acento ecológico de la bioética global de Potter y que podrían considerarse como presupuestos divergentes útiles para enriquecer la bioética global en la actualidad.

the text seeks to expand the boundaries of the concept of "global bioethics," the core of Van Rensselaer Potter's theoretical proposal on "ecological bioethics" in his work Global Bioethics, in the face of the "ethics of the Earth" developed by the ecologist and environmentalist Aldo Leopold and the analysis of "ecosophy" raised by the philosopher and psychoanalyst Félix Guattari in The Three Ecologies. This characterization is proposed to establish theoretical assumptions around the notions of ecological bioethics and ecosophy from the perspective of global bioethics in a renewed attempt to broaden its disciplinary horizons. Three moments are established for the analysis: initially, the land ethics proposed by Arnold Leopold in his work A Sand County Almanach is characterized. Subsequently, the main aspects of "ecological ethics" in Global Bioethics are analyzed. Finally, several aspects of Félix Guattari's ecosophy are highlighted that put into perspective the ecological accent of Potter's global bioethics, which could be considered valid divergent presuppositions to enrich global bioethics today.

Reabilitação estética com facetas e coroas cerâmicas em dissilicato de lítio: relato de caso / Aesthetic rehabilitation with ceramic facets and crowns in lithium disilicate: case report

Introdução: A procura pela estética do sorriso é crescente na Odontologia, pois, muitas vezes um sorriso alinhado e periodonto saudável não são o bastante. A cerâmica odontológica apresenta-se como uma ótima possibilidade restauradora, visto o avanço das técnicas de adesão entre o substrato dentário e as cerâmicas, torna-se mais previsível o resultado com este tipo de reabilitação. Objetivo: O presente artigo tem como objetivo descrever um caso clínico com envolvimento de diversos níveis de desgaste dentário para reabilitação estética com cerâmica de dissilicato de lítio. Relato de caso: Paciente 36 anos, gênero feminino, apresentava insatisfação com seu sorriso devido a forma e a alteração de cor dos seus dentes superiores anteriores e pré-molares. O plano de tratamento consistiu em realizar a troca da coroa metalocerâmica por coroa total cerâmica da unidade 14, coroa total cerâmica nas unidades 11, 21 e 22, facetas cerâmicas nas unidades 15, 13, 12, 23, 24 e 25, osteotomia e gengivoplastia das regiões de 2º prémolar superior esquerdo ao 2º pré-molar superior direito, clareamento dental caseiro da arcada inferior e placa oclusal superior de proteção. O material de escolha para a resolução do caso clínico foi a cerâmica vítrea reforçada à base de dissilicato de lítio, pois, possui um índice de refração de luz semelhante à estrutura dentária, sem interferência significativa da translucidez, além de ser passível de cimentação adesiva por se tratar de uma cerâmica ácido sensível e o tamanho do cristal e a sua disposição favorecem o aumento das propriedades mecânicas da restauração. Conclusão: O plano de tratamento realizado permitiu o restabelecimento da função e estética, com reprodução das características dos dentes naturais e promoção da jovialidade e da harmonia no sorriso(AU)

Introduction:The demand for smile aesthetics is growing in Dentistry, because, often a smile aligned and healthy periodontium are not enough. Dental ceramics, presented as an excellent restorative possibility, since the advancement of adhesion techniques between the dental substrate and the ceramics, becomes more predictable the result with this type of rehabilitation. Objective: This article aims to describe a clinical case involving several levels of dental wear for aesthetic rehabilitation with ceramics. Case Report: A 36-year-old female patient presented dissatisfaction with her smile due to the shape and color alteration of her anterior and premolar upper teeth. The treatment plan consisted of exchanging the metal-ceramic crown for the total ceramic crown of unit 14, total ceramic crown in units 11, 21 and 22, ceramic veneers in units 15, 13, 12, 23, 24 and 25, osteotomy and gingivoplasty of the regions from 2nd left upper premolar to 2nd right upper premolar, home tooth whitening of the lower arch and upper occlusal plate of protection. The material of choice for the resolution of the clinical case was the glass ceramic reinforced on the basis of lithium disilicate because it has a refractive index of light similar to the dental structure, without significant interference of translucency, besides being liable to adhesive cementation because it is a sensitive acid ceramic and the size of the crystal and its disposition favor the increase of the mechanical properties of the restoration. Conclusion: The treatment plan performed allowed the restoration of function and aesthetics, with reproduction of the characteristics of natural teeth and promotion of joviality and harmony in the smile(AU)

Socioeconomic Determinants of Demand for Dental Cosmetic Treatments

Introduction: The demand for cosmetic dentistry is a growing trend globally. Increased media coverage, availability of free online information, and the improved economic status of the general population have led to an increase in the patient’s aesthetic expectations. Since no study has measured the relationship between the economic status of people and the choice of cosmetic dentistry in Iran and due to the growing demand for it, this study was designed. Method: In this descriptive epidemiological study, we visited three completely different areas in terms of Socioeconomic status (SES) in Tehran. A checklist was used to record the gender, job, age, education level, maternal status, and source of payment for cosmetic dentistry treatment. Result: The majority of the volunteers for dental cosmetic restoration were 23?26 years. Of 498 cosmetic restoration volunteers, 50 were men and 448 were women. As for the education level, most of the participants had a high school diploma. The cost of cosmetic restoration of 351 patients (70%) was paid by the parents or the spouse, and 147 patients paid the cost from their income. Our study showed that 7% of visits to dental clinics were only for cosmetic treatment demands in Tehran in 2021. Conclusion: Type of job, education level, and marital status had no significant relationship with the choice of cosmetic treatment while age had a significant relationship with the choice of cosmetic dental restoration treatment. In addition, the choice of cosmetic dental treatment was completely related to gender, and women were the main users of it.

Aplicação do ultrassom microfocado no rejuvenescimento facial: uma revisão da literatura / Application of microfocused ultrasound in facial rejuvenation: a literature review

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.

Campo eletromagnético focado de alta intensidade para o tratamento da celulite / High-intensity focused electromagnetic field treatment for cellulite

Introdução: O tratamento com campo eletromagnético focado de alta intensidade (HIFEM) usa ondas eletromagnéticas de baixa frequência para induzir contrações musculares, causando hipertrofia muscular e reduzindo a gordura subcutânea. Objetivo: avaliar os efeitos de um tratamento com HIFEM na celulite nos glúteos. Métodos: trinta mulheres foram recrutadas e randomizadas em 2 grupos que receberam 8 ou 12 sessões de HIFEM na região dos glúteos. A celulite foi avaliada utilizando a Cellulite Severity Scale, a Global Aesthetic Improvement Scale e um questionário de satisfação. Mudanças na composição corporal foram avaliadas com bioimpedância e medidas da circunferência do quadril. Resultados: a aparência global da região glútea das pacientes melhorou com o tratamento. Houve melhora na celulite de algumas pacientes, mas para a maioria a melhora não foi grande o suficiente para resultar em uma mudança de classificação na Cellulite Severity Scale. A satisfação foi alta e os eventos adversos foram poucos, não-graves e transitórios. Conclusão: os efeitos do tratamento com HIFEM na celulite da região glútea são sutis. Contudo, este tratamento é capaz de melhorar globalmente a aparência da região glútea, melhorando a percepção das pacientes sobre a gravidade de sua celulite

Introduction: High-intensity focused electromagnetic field treatment (HIFEM) uses low-frequency electromagnetic waves to induce supramaximal muscle contractions, causing muscle hypertrophy and reducing fat. Objective: To evaluate the effects of a HIFEM treatment for the improvement of cellulite on the buttocks. Methods: Thirty patients were divided into two groups that received eight or 12 HIFEM sessions on the buttocks for six weeks. We assessed the improvement in cellulite and the buttocks' global appearance through the Cellulite Severity Scale (CSS), the Global Aesthetic Improvement Scale (GAIS), and a satisfaction questionnaire. Changes in body composition were evaluated through bioimpedance and hip circumference measurements. Results: Patients from both groups improved the global appearance of their buttocks. Cellulite lesions of some patients improved, but for most patients, the improvement wasn't great enough to change the grade on the Cellulite Severity Scale. Patient satisfaction was high and adverse events were few, minor, and transitory. Conclusion: The effects of HIFEM on cellulite are subtle, as this treatment modality cannot address the fibrous septa that cause the depressed lesions of cellulite. Nevertheless, HIFEM procedures can improve the buttocks' global appearance, enhancing the patients' subjective perception of their cellulite.

Relationship between eyebrow and eye aesthetics after correction of aponeurotic ptosis / 中华医学美学美容杂志

Objective:To evaluate the specific changes and importance of the proportions of the eyebrows and eyes after surgery by analyzing and measuring the changes of the values of the eyebrows and eyes in elderly patients with aponeurotic ptosis before.Methods:A total of 54 cases (108 eyes) of elderly patients with aponeurotic ptosis who were treated in our department from 2019.01 to 2020.12 were collected preoperatively and 6 months postoperatively, and they were set as the study group. At the same time, the data of 48 cases (96 eyes) of healthy people with good face were collected and set as the young control group, and the data of 50 cases (100 eyes) of elderly healthy people without ptosis were collected and set as the elderly control group. The corresponding objective data were analyzed, and the specific changes and proportional relationship of eyebrows and eyes after surgery were evaluated.Results:Compared with the preoperative data, the marginal reflex distance 1 (MRD1), the height of the palpebral fissure (HPF) in the study group increased at 6 months after the operation, and the distance between the eyebrow and eye at each site increased or shortened ( P<0.05). Six months after the operation, the brow height from medial canthus (MBH), the central brow and eye distance (brow height from upper eyelid margin on midpupillary level, CBH), and the lateral brow and eye distance (brow height from lateral, LBH) had been changed. The change rates of canthus compared with preoperatively were that (88.29±11.69)%, (85.04±14.96)%, and (93.61±13.56)%, respectively, among which CBH shortened most significantly, and the shortened distance was (3.76±2.43) mm. The MRD1 and HPF in the group increased significantly at 6 months after operation, which were significantly greater than those in the elderly control group ( P<0.05). CBH was significantly shortened ( P<0.05); compared with preoperative, the ratio of HPF/CBH, HPF/length of the palpebral fissure (LPF) in the study group increased at 6 months after operation, and the lateral canthus brow tail line [ratio of lateral canthus to lateral end of eyebrow (LLE)]/LPF decreased ( P<0.05); HPF/CBH in the study group was lower than that in the young control group at 6 months after operation, but greater than that in the elderly control group ( P<0.05). Monthly HPF/LPF was significantly higher than that of the elderly control group ( P<0.05), and the LLE/LPF of the study group was significantly higher than that of the young control group at 6 months after operation ( P<0.05); intraoperative levator muscle shortening (LMS) was negatively correlated with postoperative MBH, CBH and LBH ( P<0.05), among which LMS had the greatest correlation with CBH ( r=-0.587). Conclusions:After ptosis correction, the palpebral fissures are larger, the distance between the eyebrows and the eyes is shortened, and there is a certain proportional relationship. After surgery, the patient's eyebrow-eye ratio is better than that of the elderly in the same age group, and it is closer to the young people, and the intraoperative LMS has a correlation with the eyebrow-eye distance, which can be used as a factor to predict the shortened distance of the eyebrow-eye distance.

Analysis of smile exposure and related factors in young people aged 20 to 30 with convex facial profiles / 口腔疾病防治

Objective @#To study smile exposure in 20- to 30-year-olds with convex facial profiles and to explore the correlation between smile exposure and other aesthetic indicators, as well as psychological factors. @*Methods @# This study obtained ethical approval from the hospital. After they gave informed consent and portrait authorization, 80 young subjects aged 20-30 with convex facial profiles had their dynamic postural smile and spontaneous laughter recorded. The videos were imported into Photoshop CC software, key frames were selected, and the smile exposure was measured. The three-dimensional information of the subject's face in a resting state was obtained, the relevant aesthetic indicators were measured, and the satisfaction degree of their smile and laughter were evaluated. Correlation analysis was conducted for smile exposure and the relevant aesthetic indicators and subjective psychological evaluation.@*Results @# There were statistically significant differences in smile exposure, smile patterns, relevant aesthetic indicators and subjective psychological evaluation between males and females aged 20 to 30 (P<0.05). There was a large gap between males and females in the average opening degree when laughing, males having 5 times that of females, while the average gingival exposure height of the maxillary central incisor in males was approximately 1/2 of that in females. The average nasolabial angle of males (99.80° ± 7.96°) was larger than that of females (96.26° ± 7.31°) (P<0.05), while the average ratio of upper lip length to the length of the lower 1/3 of the face of males (33.73% ± 2.35%) was less than that of females (38.57% ± 2.76%) (P<0.05). The average psychological score of males (57.75±13.46) was higher than that of females (53.69±17.95) (P<0.05). The ratios of maxillary teeth and gingival exposure to oral fissure in the postural smile were positively correlated with the nasolabial angle. The oral fissure width in spontaneous laughter was negatively correlated with psychological score.@*Conclusion @# Convex-faced males and females aged 20 to 30 have different smile exposures and smile patterns. Males tend to smile more openly with a larger opening and less gingival exposure, while females tend to grin with a small opening and more gingival exposure. Smile exposure is positively correlated with nasolabial angle and negatively correlated with smile satisfaction.

Does Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) reflect the impact of malocclusion on facial aesthetics?

ABSTRACT Introduction: Malocclusion is presumed to have adverse effects on dental and facial attractiveness, leading to deleterious psychosocial impact and Quality of life(QoL) of the individual. The Psychosocial Impact of Dental Aesthetic Questionnaire (PIDAQ) has proved to be effective for assessment of psychosocial impact of malocclusion on dental aesthetics, but it's effectiveness for assessing facial aesthetics is unknown. Objective: The aim of the present study was to assess the effectiveness of PIDAQ on its ability to reflect the psychosocial impact of malocclusion on facial attractiveness, using the Facial Aesthetic index (FAI) after its translation and validation in the regional language. Methods: The 23-item PIDAQ, after translation process, cross-cultural adaptation and pilot testing, was administered to 330 subjects (62.5 % females and 37.5 % males; age range 18-30 years) with varying degrees of severity of malocclusion, assessed by the two components of the Index of Orthodontic Treatment Need (Dental Health Component, IOTN-DHC, for normative need; and self-administered Aesthetic Component, IOTN-AC, for subjective need) and FAI. Results: The internal consistency and test-retest reliability were good (Cronbach's alpha = 0.859 - 0.958; Intraclass correlation coefficient =0.984). FAI, IOTN-DHC and IOTN-AC scores showed highly significant correlation with PIDAQ scores, depicting strong convergent validity (p< 0.001). One-way analysis of variance (ANOVA) and Bonferroni post-hoc test showed highly significant correlations (p-value < 0.001) for all comparisons. There were no significant differences between responses of males and females. The regional version of PIDAQ had excellent reliability. Conclusions: PIDAQ showed good psychometric properties and was able to effectively reflect the psychosocial impact of malocclusion on altered facial aesthetics.

RESUMO Introdução: Acredita-se que a má oclusão tenha efeitos adversos na estética dentária e facial, levando a um impacto psicossocial e na qualidade de vida (QV) do indivíduo. O questionário PIDAQ (Psychosocial Impact of Dental Aesthetic Questionnaire) provou ser eficaz para avaliação do impacto psicossocial da má oclusão na estética dental, mas sua eficácia para avaliar a estética facial é desconhecida. Objetivo: O objetivo do presente estudo foi avaliar a eficácia do PIDAQ em refletir o impacto psicossocial da má oclusão na atratividade facial, usando o Índice de Estética Facial (FAI) após sua tradução e validação na linguagem regional. Métodos: O PIDAQ com 23 itens, após o processo de tradução, adaptação transcultural e teste piloto, foi administrado a 330 indivíduos (62,5% do sexo feminino e 37,5% do sexo masculino; faixa etária de 18 a 30 anos) com má oclusão de gravidade variada, avaliados pelos dois componentes do Índice de Necessidade de Tratamento Ortodôntico (Componente de Saúde Dentária, IOTN-DHC, para necessidade normativa; e Componente Estético auto-administrado, IOTN-AC, para necessidade subjetiva) e pelo FAI. Resultados: A consistência interna e a confiabilidade teste-reteste foram boas (alfa de Cronbach = 0,859-0,958; coeficiente de correlação intraclasse = 0,984). Os escores FAI, IOTN-DHC e IOTN-AC mostraram correlação altamente significativa com os escores do PIDAQ, representando forte validade convergente (p< 0.001). A análise de variância (ANOVA) de uma via e o teste post-hoc de Bonferroni mostraram correlações altamente significativas (p < 0,001) para todas as comparações. Não houve diferenças significativas entre as respostas de homens e mulheres. A versão regional do PIDAQ apresentou excelente confiabilidade. Conclusões: O PIDAQ mostrou boas propriedades psicométricas e foi capaz de refletir efetivamente o impacto psicossocial da má oclusão na estética facial alterada.

Estimation du succès fonctionnel et esthétique des implants dentaires / Estimation of the functional and aesthetic success of dental implants

Les implants dentaires ont révolutionné la réhabilitation orale partielle et totale. Des taux de succès allant de 80% à 100% à travers le monde (Buser, 2019) Le succès du traitement implantaire doit répondre à deux objectifs pour être validé. Le premier est le concept d'ostéointégration et le second sur l'aspect esthétique des tissus autour de l'implant. notre objectif était d'estimer le taux de succès fonctionnel, en se basant sur les critères de succès d'Albrektsson et coll (Albrektsson,1986 ) ainsi qu'une évaluation esthétique par le PES (Belser, 2009) sur un échantillon de 50 patients dont 107 implants posés au secteur antérieur où le profil esthétique joue un rôle important. Le taux de succès fonctionnel était estimé à 94% voire 03 échecs sur 50 patients, avec une différence significative entre le succès implantaire et le degré d'hygiène bucco dentaire (p=0.00001) ; ainsi que le degré d'inflammation (p=0.0000) et la maladie parodontale p=0.04. On a eu 100% de succès chez les patients à qui on a procédé à un enfouissement total de l'implant. Enfin le succès esthétique était bon chez 42(84%) patients pour un score de 8 à10, et favorable chez les 5(10 %) restants pour un score de 5 à 7

Dental implants have revolutionized partial and total oral rehabilitation. Success rates ranging from 80% to 100% worldwide (Buser, 2019) The success of the implant treatment must meet two objectives to be validated. The first is the concept of osseointegration and the second on the aesthetic appearance of the tissues around the implant. Our objective was to estimate the functional success rate, based on the success criteria of Albrektsson et al (Albrektsson, 1986) as well as an aesthetic evaluation by the PES (Belser, 2009) on a sample of 50 patients including 107 implants placed in the anterior sector where the aesthetic profile plays an important role. The functional success rate was estimated at 94% or even 03 failures out of 50 patients, with a significant difference between the implant success and the degree of oral hygiene (p=0.00001); as well as the degree of inflammation (p=0.00001) and finally the periodontal disease (p=0.04). We have had 100% success in patients who have undergone total burying of the implant Finally, aesthetic success was good in 42 (84%) patients for a score of 8 to 10, and favorable in the remaining 5 (10%) for a score of 5 to 7.

Prospective study of the aesthetic effect of botulinum toxin a when injected into the muscles of facial expression

Botulinum neurotoxin A (BoNT-A) causes an anticholinergic effect on neuronal fibers, which control muscle contraction and autonomic disorders. Thus, it has been widely used in facial aesthetics, decreasing the action of motor muscles and consequent wrinkles. This preliminary study evaluated the effect of BoNT-A in 77 patients, the treatment satisfaction index was defined in percentage (from 0% to 100%). The evaluation was carried out on 15th, 30th, 60th, 90th, and 180th days after BoNT. The data were analyzed using the Friedman, Student t, Mann-Whitney test with t (alpha=0.05). The results showed that at 15th and 30th days the scores were similar in all muscles with high level of satisfaction and until 90th days the scores decreased significantly for Corrugator supercilii 79.38%, Occipitofrontalis 71.46%, Orbicularis oculi 70.43%; but the satisfaction was good. At 180 days, there was a drop in effectiveness in all treated muscles since the scores decreased significantly, showing low satisfaction by the participants. This study demonstrated that the BoNT-A had attested satisfaction effect by participants for up to 90th days, but at 180th days the satisfaction was low. In the comparative analyzes between women under 40 and over 40 years of age, there was no significant differences.

Rinoplastia secundaria en pacientes con fisura labiopalatina / Secondary Rhinoplasty in Patients with Clef lip and Palate

Introducción: La deformidad nasal asociada con el labio leporino ha sido vista como uno de los problemas reconstructivos más desafiantes en la rinoplastia, hasta el momento no se ha acordado ningún método único para cuantificar el éxito del tratamiento. En el año 2006 se aprobó oficialmente el protocolo para el tratamiento de las deformidades nasales complejas del Hospital Clínico Quirúrgico "Hermanos Ameijeiras", que están incluidas, las deformidades nasales congénitas secundarias en el adulto, no se recogen antecedentes de resultados en este grupo de pacientes basados en mediciones objetivas. Objetivo: Evaluar los resultados estéticos de la rinoplastia secundaria en pacientes con fisura labiopalatina. Métodos: Se realizó un estudio analítico a través de mediciones nasales angulares y de áreas, comparadas en fotografías estandarizadas entre el pre y posoperatorio y se determinó el índice de asimetría según la fórmula de Nakamura. Un panel de expertos usó la escala de Asher McDade y realizó la evaluación subjetiva de las imágenes, que permitió calcular el índice estético antes y después del tratamiento. Resultados: Se obtuvo una reducción marcada de todos los índices de asimetría nasal entre el pre y posoperatorio, así como una mejoría del índice estético posoperatorio pasándose de una apariencia pobre a muy buena apariencia. Conclusiones: Con la aplicación del protocolo para el tratamiento de las deformidades nasales del paciente fisurado adulto del Hospital Clínico Quirúrgico "Hermanos Ameijeiras" se obtienen buenos resultados estéticos(AU)

Introduction: Nasal deformity associated with cleft lip has been seen as one of the most challenging reconstructive problems in rhinoplasty; up to date, no single method has been agreed upon to quantify management success. In 2006, the protocol for managing complex nasal deformities was officially approved by Hermanos Ameijeiras Clinical Surgical Hospital, which includes secondary congenital nasal deformities in adults; however, there is no history of outcomes in this group of patients based on objective measurements. Objective: To assess the aesthetic outcomes of secondary rhinoplasty in patients with cleft lip and palate. Methods: An analytical study was carried out through linear and angular nasal measurements, compared in standardized photographs between the pre- and postoperative period; while the asymmetry index was determined according to Nakamura's formula. A panel of experts used the Asher McDade scale and performed the subjective assessment of the images, which allowed calculation of the esthetic index before and after the procedure. Results: A marked reduction was obtained in all nasal asymmetry indexes between the pre- and postoperative periods; as well as an improvement in the postoperative aesthetic index, from a poor appearance to a very good appearance. Conclusions: With the application of the protocol for managing nasal deformities of the adult cleft patient of Hermanos Ameijeiras Clinical Surgical Hospital, good esthetic outcomes are obtained(AU)

O momento estético como potencialidade de vida e de futuro / The aesthetic moment as a potentiality for life and the future / Le moment esthétique comme potentialité de vie et de l'avenir / El momento estético como potencial de vida y futuro

Este artigo é uma reflexão teórica acerca de algumas potencialidades do momento estético: este se configura, a um só tempo, como refúgio das intempéries do presente, como possibilidade de fortalecimento dos laços do indivíduo com a vida e como abertura para o futuro. A relação do pianista inglês James Rhodes com a música clássica, conforme narrada por ele em sua autobiografia, é apresentada como expressão de tais potencialidades. Em nossa argumentação, descrevemos o momento estético como momento de afrouxamento das fronteiras do self, que atualiza, até certo ponto, a relação primordial do bebê com o objeto materno. Enfatizamos os limites do momento estético, já que este não substitui a necessidade do encontro humano, mas indicamos que ele pode se apresentar como uma espécie de lugar de espera suportável que mantém aberto o horizonte do encontro.

Resumos This paper is a theoretical reflection on some potentialities of the aesthetic moment: this is configured, at the same time, as a refuge from the storms of the present, as a possibility to strengthen the individual's ties with life, and as an opening to the future. The English pianist James Rhodes's relationship with classical music, as narrated by him in his autobiography, is presented as an expression of such potentialities. During its argumentation, the text describes the aesthetic moment as a moment of loosening of the boundaries of the self, which updates, to a certain extent, the infant's primordial relationship with the maternal object. The article emphasizes the limits of the aesthetic moment, as it does not replace the need for human interaction, while indicating its potential as a kind of bearable waiting place which keeps the horizon of the encounter open.

Cet article est une réflexion théorique sur certaines potentialités du moment esthétique: celui-ci se configure, à la fois, comme un refuge contre les tempêtes du présent, comme une possibilité de renforcer les liens de l'individu avec la vie, et comme une ouverture vers l'avenir. La relation du pianiste anglais James Rhodes avec la musique classique, telle qu'il la raconte dans son autobiographie, est présentée comme une expression de ces potentialités. Au cours de l'argumentation, le texte décrit le moment esthétique comme un moment de relâchement des frontières du soi, qui actualise, dans une certaine mesure, la relation primordiale du nourrisson avec l'objet maternel. L'article souligne les limites du moment esthétique, car il ne remplace pas le besoin de la rencontre humaine, tout en indiquant son potentiel comme une sorte de lieu d'attente supportable qui maintient ouvert l'horizon de la rencontre.

Violet LED-Based Tooth Whitening and Resin Composite Restorations to Reestablish Smile Aesthetics Case Report

ABSTRACT: This clinical case described the aesthetic treatment of a patient complaining about the aspect of their upper teeth. After anamnesis and clinical examination, the association of tooth whitening photoactivated by violet LED and resin composite restorations was indicated. Prior to restorative treatment, three bleaching sessions were performed with low concentration hydrogen peroxide (6 %; Nano white flex) for 30 minutes. During this period, violet LED irradiation was intercalating performed every 1 minute, totalizing 15 minutes. Ten days after the final bleaching session, old restorations in the upper lateral incisors were removed for better color selection of resin composites. Then, all upper anterior teeth were directly restored with nanofilled resin composite (Filtek Z350XT), reestablishing anatomy, form, and function. At the end of the treatment, the association of techniques proved to be cost-effective, restoring the esthetics satisfactorily and promoting the patient's well-being by a minimally invasive approach.

RESUMEN: En este reporte de caso se describió el tratamiento para una paciente que se quejaba del aspecto de sus dientes superiores. Tras anamnesis y exploración clínica, se indicó la asociación de blanqueamiento dental fotoactivado por LED violeta y restauraciones de resina compuesta. Antes del tratamiento restaurador, se realizaron tres sesiones de blanqueamiento con peróxido de hidrógeno de baja concentración (6 %; Nano white flex) durante 30 minutos. Durante este período, la irradiación con LED violeta se intercalaba cada 1 minuto, totalizando 15 minutos. Diez días después de la última sesión de blanqueamiento, se retiraron las restauraciones antiguas de los incisivos laterales superiores para una mejor selección del color de la resina compuesta. Luego, todos los dientes anteriores superiores fueron restaurados de manera directa con resina de nanorrelleno (Filtek Z350XT), restableciendo la anatomía, forma y función. Al final del tratamiento, la asociación de las técnicas resultó beneficioso, restaurando la estética de forma satisfactoria y promoviendo el bienestar de la paciente mediante un abordaje mínimamente invasivo.

Anterior aesthetic restoration with ultrathin porcelain veneers on asymmetric faces assisted by a four-dimensional smile design: a case report and literature review / 口腔疾病防治

Objective@#To explore the application effect of a four-dimensional smile design as the leading and facial streamline as the reference system in the aesthetic restoration of anterior teeth.@*Methods@# A case of scattered space in anterior teeth was treated with a four-dimensional smile design and digital aesthetic restoration with ultrathin porcelain veneer. The digital information of the patients was obtained through oral and facial scanning, and a four-dimensional smile design and prediction were carried out. After the treatment plan was jointly determined by doctors and patients, minimally invasive abutment preparation was carried out, and ultrathin porcelain veneer was made and bonded in place. After the operation, the esthetic degree and marginal fit were observed and reexamined one year after the repair.@* Results @#The edges of the ultrathin ceramic veneers were naturally tight, and the color was coordinated, with satisfying pink and white esthetics. The face was more harmonious and natural when smiling. One year after the restoration, the facial aesthetics were wonderful, the abutment teeth and periodontal tissues were healthy, and the patients were satisfied. The results of the literature review showed that the fitting of temporal facial scanning and intraoral scanning data can accurately predict four-dimensional smile aesthetics, simulate the real state of the dynamic smile and pronunciation process, and combine it with facial streamlines to design a natural and coordinated personalized smile for patients with asymmetric faces. However, for patients with occlusal changes, unstable occlusion or temporomandibular joint disorder, it is necessary to add data fitting, such as electronic facial arch and cone beam CT, to more accurately simulate postoperative mandibular movement.@*Conclusion@# With a four-dimensional smile design as the leading and facial streamline as the reference system, the whole process digital design assisted the restoration of asymmetric anterior teeth with ultrathin porcelain veneer and had a good effect. The postoperative smiling of patients is harmonious and beautiful, which is in line with the expected effect. Patient participation and satisfaction are high; thus, this method is worthy of clinical promotion.
