RESUMEN
BACKGROUND: The aim of this study was to evaluate changes in lip metrics before and after facial rejuvenation treatment with hyaluronic acid-based fillers and to compare them with those of a control group using stereophotogrammetry (3D). METHODOLOGY: This study included 63 Caucasian women divided into Group C (<30 years, n=30) and Group H (>30 years, n=33), which was further divided into before (HT0) and after (HT1) lip augmentation with hyaluronic acid (HA). Eleven anthropometric landmarks were identified for linear, angular, and surface area measurements. Three photos were captured in Group C, while Group H had photos taken at T0 and T1. Statistical analysis was conducted using the Shapiro-Wilk test to evaluate normality, the Kruskal-Wallis test and one-way ANOVA. Tukey's post hoc and pairwise comparison tests were performed to analyze differences between variables (P value < 0.05). RESULTS: There were significant differences between lip width (ChR-ChL) and philtrum width (CphR-CphL) (P<.001). The total heights of the upper (Ls-Li) and lower vermilion lips (Sto-Li) increased, and the heights of the upper (Sn-Ls) and lower (Li-Sl) cutaneous lips decreased. The angles related to the philtrum (ChR-CphR-Ls, P<.001; ChL-CphL-Ls, P<.001) and nasolabial angle (Prn-Sn-Ls) (P<.001) exhibited significant differences. The surface areas of the upper, lower, and total vermilion lip showed significant differences (P<.001). Tukey's test indicated no significant differences in surface area after lip augmentation between the HT1 and C groups. CONCLUSION: Analysis of lip morphology after a filler procedure revealed a reversal of age-related changes, with increases in vermilion lip height and surface area comparable to those of younger individuals.

RESUMEN
INTRODUCTION: Symmetry is balance, some correspondence in the size, form, and arrangements of parts on opposite sides of a plane, line, or point. The opposite of this concept is asymmetry, or imbalance. OBJECTIVE: This retrospective study compared two methods for assessing arch symmetry with linear measurements based on triangles, to determine their applicability and efficiency. METHODS: Two groups were enrolled: children (n=20) and adults (n=20), and the arch symmetry was assessed from linear measurements. Method 1: the incisor-canine (INC), canine-molar (CM), and incisor-molar (INM) distances (paired t-test and Pearson correlation). Method 2: a mathematical equation between the cusps measurements of the canines and the distobuccal of the first molars leading to result 1 (t-test for one sample and bootstrapping analysis). Dental casts were digitized and analyzed using a software program. The Bland-Altman test compared the methods (α=0.05). RESULTS: The Bland-Altman test revealed concordance between the methods; however, separately the results were different: In method 1, the mandibular arch did not demonstrate correlation (children, INC r=0.33; CM r=0.45; INM r=0.51; adults, CM r=0.46; INM r=0.35), however, the maxilla revealed a strong correlation in children and a strong/moderate correlation in adults. In method 2, both arches were symmetrical (p>0.05). CONCLUSION: Method 1 may be appropriate during orthodontic treatment, and method 2 may be indicated for final treatment. These methods are useful; however, only method 1 identified the side of asymmetry. The methods can contribute to future studies in syndromic and non-syndromic patients, before and after orthognathic surgeries and orthodontic treatment, comparing results.

This study aimed to assess and quantify the morphologic characteristics of the lips and the lower third of the face in cleft and noncleft patients, utilizing three-dimensional (3D) stereophotogrammetry. Sixty patients were included in the study, comprising 30 unilateral cleft lip and palate patients (G1, 24 female, 6 male; aged 20 to 60 y, mean age 44.0±12.0 y) and 30 noncleft patients (G2, 23 female, 7 male; aged 20 to 59 y, mean age 43.5±12.0 y). Anthropometric landmarks were identified on the facial surface. Three-dimensional stereophotogrammetry was employed to capture images. Statistical analysis was conducted to compare the groups, with a significance level set at 0.05. The comparative analysis revealed statistically significant differences in 5 linear and 6 angular measurements. Linear measurements such as philtrum width, upper and lower cutaneous lip height, mandibular ramus length, and midfacial depth exhibited significant differences between cleft and noncleft patients. Similarly, angular measurements, including upper lip angle, Cupid's bow angle, lower/medium face convexity, lip seal, nasolabial angle, and left gonial angle, displayed statistically significant disparities. These findings underscore the ongoing surgical challenges in the comprehensive rehabilitation of patients with clefts, highlighting the critical need for continued advancements in treatment strategies.

OBJECTIVES: This investigation aimed to assess the optimal timing for lip repair in children with cleft lip and palate via 3D anthropometric analysis to evaluate their maxillofacial structures. METHODS: The sample comprised 252 digitized dental models, divided into groups according to the following timing of lip repair: G1 (n = 50): 3 months; G2 (n = 50): 5 and 6 months; G3 (n = 26): 8 and 10 months. Models were evaluated at two-time points: T1: before lip repair; T2: at 5 years of age. Linear measurements, area, and Atack index were analyzed. RESULTS: At T1, the intergroup analysis revealed that G1 had statistically significant lower means of I-C', I-C, C-C', and the sum of the segment areas compared to G2 (p = 0.0140, p = 0.0082, p = 0.0004, p < 0.0001, respectively). In addition, there was a statistically significant difference when comparing the cleft area between G2 and G3 (p = 0.0346). At T2, the intergroup analysis revealed that G1 presented a statistically significant mean I-C' compared to G3 (p = 0.0461). In the I-CC' length analysis, G1 and G3 showed higher means when compared to G2 (p = 0.0039). The I-T' measurement was statistically higher in G1 than in G2 (p = 0.0251). In the intergroup growth rate analysis, G1 and G2 showed statistically significant differences in the I-C' measurement compared to G3 (p = 0.0003). In the analysis of the Atack index, there was a statistically significant difference between G1 and the other sample sets (p < 0.0001). CONCLUSION: Children who underwent surgery later showed better results in terms of the growth and development of the dental arches.
RESUMEN
Ctenoluciidae is a Neotropical freshwater fish family composed of two genera, Ctenolucius (C. beani and C. hujeta) and Boulengerella (B. cuvieri, B. lateristriga, B. lucius, B. maculata, and B. xyrekes), which present diploid number conservation of 36 chromosomes and a strong association of telomeric sequences with ribosomal DNAs. In the present study, we performed chromosomal mapping of microsatellites and transposable elements (TEs) in Boulengerella species and Ctenolucius hujeta. We aim to understand how those sequences are distributed in these organisms' genomes and their influence on the chromosomal evolution of the group. Our results indicate that repetitive sequences may had an active role in the karyotypic diversification of this family, especially in the formation of chromosomal hotspots that are traceable in the diversification processes of Ctenoluciidae karyotypes. We demonstrate that (GATA)n sequences also accumulate in the secondary constriction formed by the 18 S rDNA site, which shows consistent size heteromorphism between males and females in all Boulengerella species, suggesting an initial process of sex chromosome differentiation.

In this study, we analyzed the potential of viral infections in the species Homo sapiens as environmental causes of orofacial clefts (OFCs). A scoring system was adapted for qualitatively assessing the potential of viruses to cause cleft lip and/or palate (CL/P). This assessment considered factors such as information from the literature, nucleotide and amino acid similarities, and the presence of Endogenous Viral Elements (EVEs). The analysis involved various algorithm packages within Basic Local Alignment Search Tool 2.13.0 software and databases from the National Center for Biotechnology Information and the International Committee on Taxonomy of Viruses. Twenty significant viral species using different biosynthesis strategies were identified: Human coronavirus NL63, Rio Negro virus, Alphatorquevirus homin9, Brisavirus, Cosavirus B, Torque teno mini virus 4, Bocaparvovirus primate2, Human coronavirus HKU1, Monkeypox virus, Mammarenavirus machupoense, Volepox virus, Souris mammarenavirus, Gammapapillomavirus 7, Betainfluenzavirus influenzae, Lymphocytic choriomeningitis mammarenavirus, Ledantevirus kern, Gammainfluenzavirus influenzae, Betapolyomavirus hominis, Vesiculovirus perinet, and Cytomegalovirus humanbeta5. The evident viral etiological potential in relation to CL/P varies depending on the Baltimore class to which the viral species belongs. Given the multifactorial nature of CL/P, this relationship appears to be dynamic.

BACKGROUND: Denture biofilm acts as a potential reservoir for respiratory pathogens, considerably increasing the risk of lung infections, specifically aspiration pneumonia, mainly 48h after hospital admission. The establishment of a straightforward, affordable, and applicable hygiene protocol in a hospital environment for the effective control of denture biofilm can be particularly useful to prevent respiratory infections or reduce the course of established lung disease. OBJECTIVES: To evaluate the anti-biofilm effectiveness of denture cleaning protocols in hospitalized patients. METHODOLOGY: The maxillary complete dentures (MCDs) of 340 hospitalized participants were randomly cleaned once using one of the following 17 protocols (n=20): brushing with distilled water, toothpaste, or neutral liquid soap (controls); immersion in chemical solutions (1% sodium hypochlorite, alkaline peroxide, 0.12% or 2% chlorhexidine digluconate), or microwave irradiation (650 W for 3 min) combined or not with brushing. Before and after the application of the protocols, the biofilm of the intaglio surface of the MCDs was evaluated using two methods: denture biofilm coverage area (%) and microbiological quantitative cultures on blood agar and Sabouraud Dextrose Agar (CFU/mL). Data were subjected to the Wilcoxon and Kruskal-Wallis tests (α=0.05). RESULTS: All 17 protocols significantly reduced the percentage area of denture biofilm and microbial and fungal load (P<0.05). The highest percentage reductions in the area of denture biofilm were observed for 1% hypochlorite solution with or without brushing and for 2% chlorhexidine solution and microwave irradiation only in association with brushing (P<0.05). The greatest reductions in microbial and fungal load were found for the groups that used solutions of 2% chlorhexidine and 1% hypochlorite and microwave irradiation, regardless of the association with brushing (P<0.05). CONCLUSIONS: A single immersion for 10 min in 1% sodium hypochlorite, even in the absence of brushing, proved to be a straightforward, rapid, low-cost, and effective protocol for cleaning the dentures of hospitalized patients.

OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the clinical and mycological effectiveness of mucoadhesives as vehicles for drugs or natural products in the treatment of oral candidiasis. MATERIALS AND METHODS: The search for articles was carried out in the Medline/PubMed, SCOPUS, EMBASE, Web of Science, Cochrane Library, and SciELO databases before August 2023. We selected the studies, extracted the data, evaluated the study quality, graded the evidence, performed the risk of bias, and carried out meta-analysis. RESULTS: A total of 389 potentially relevant articles were identified, and 11 studies (1869 participants) met the inclusion criteria of the systematic review. The overall risk of bias was considered low. The most common presentation of mucoadhesives was tablets, with miconazole being the most frequently drug used in the delivery system. Mucoadhesives demonstrated comparable efficacy with topical or systemic antifungal agents, with no significant differences between treatments in terms of clinical (RR = 0.907; 95CI = 0.3-1.297; p = 0.591; I2 = 64.648) or mycological (RR = 0.95; 95CI = 0.667-1.360; p = 0.789; I2 = 73.271) efficacy. CONCLUSIONS: Mucoadhesives may be a suitable alternative to conventional treatments, with the advantage of reducing the frequency of application by up to 5 times and the daily dosage by up to 20 times.

OBJECTIVES: To evaluate the quantitative values of linear and angular facial anthropometrics in patients with unilateral cleft lip and palate (UCLP) and compare them with those of patients with bilateral cleft lip and palate (BCLP) using three-dimensional (3D) facial imaging. DESIGN: Retrospective, observational, and cross-sectional study. SETTING: Hospital for Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP). PATIENTS/ PARTICIPANTS: In total, 61 non-syndromic patients with CLP who underwent multidisciplinary treatment and rehabilitated with a prosthesis were enrolled and divided into those with UCLP (G1; n = 31) and those with BCLP (G2; n = 30). INTERVENTION: Facial images were captured using a 3D camera after landmarks were marked on each patient's face. The software evaluated linear and angular parameters. Statistical tests were applied. Significance was determined as P < 0.05. MAIN OUTCOME MEASUREMENTS: Overall, 22 linear and 13 angular measurements were evaluated. RESULTS: The nasal length (P = 0.08), middle third of the face (P = 0.06), base nose width (P < 0.001), nasal root width (P < 0.001), nasal tip angle (P = 0.018), philtrum width (P < 0.001), lower face width (P = 0.039) and midfacial depth (P = 0.040) were significantly higher in G2; the upper cutaneous lip height was significantly higher in G1. Sexual dimorphism was observed except for linear measurements (linear distance between the labiale superius and labiale inferius landmarks, nasal root width, and upper cutaneous lip length) and angular measurements. CONCLUSIONS: G2 had a greater length and width of nose and nasal root, nasal tip angle, philtrum width, and lower face width, midfacial depth, and midface third than G1. These findings also revealed the presence of sexual dimorphism.

RESUMEN
A síndrome pós-COVID-19 afeta pacientes independentemente da gravidade da doença. Os sintomas mais comuns são fadiga, cefaleia, déficit de atenção, dispneia e depressão. Para ajudar na reabilitação dos pacientes, a intervenção fisioterapêutica tem sido utilizada como estratégia. Objetivo: Analisar os efeitos de um programa de reabilitação fisioterapêutica na qualidade de vida, capacidade funcional, percepção de esforço, percepção da dor e força muscular, em indivíduos com a síndrome pós-COVID-19. Métodos: Trata-se de um estudo quase experimental, com 33 indivíduos, divididos em dois grupos: intervenção (GI) que recebeu um programa de reabilitação fisioterapêutica e controle (GC) que não recebeu. Os participantes foram avaliados antes e após o período de intervenção para força, por meio de dinamometria de preensão palmar; nível de dor, pela escala visual analógica; capacidade funcional, pelo teste de caminhada de seis minutos; percepção de esforço, através da escala modificada de BORG e qualidade de vida pelo instrumento SF-36. Resultados: Observou-se no GI aumento significativo (p<0,05) da qualidade de vida nos domínios de capacidade funcional, aspectos físicos e redução da dor e aumento da força de preensão palmar. Houve diferença significativa (p<0,05) entre os grupos para percepção de esforço nos momentos antes e após as intervenções. Para as demais variáveis não foram evidenciadas diferenças significativas. Conclusão: O programa de intervenção fisioterapêutica promoveu melhora dos domínios de capacidade funcional, aspectos físicos e da dor da qualidade de vida, e aumento da força de preensão palmar de indivíduos com sintomas da síndrome pós-COVID-19.
Post-COVID-19 syndrome affects patients regardless of the severity of the disease. The most common symptoms are fatigue, migraine, attention deficit, dyspnea, and depression. Physiotherapeutic intervention has been used as a strategy to aid the rehabilitation of patients. Objective: To analyze the effects of a physiotherapeutic rehabilitation program on quality of life, functional capacity, perceived exertion, perception of pain, and muscle strength in patients with post-COVID-19 syndrome. Methods: This is a quasi-experimental study with 33 participants, divided into two groups: an intervention group (IG) who received the physiotherapeutic rehabilitation program and a control group (CG) who did not. Participants were assessed for strength before and after the intervention period, using handgrip dynamometry and being assessed with a visual analog scale (VAS) for pain, the six-minute walk test (6MWT) for functional capacity, the BORG scale for exertion perception, and the SF-36 scale for quality of life. Results: A significant increase (p<0.05) in quality of life was observed in the IG in the SF-36 domains of physical functioning, physical role limitations, bodily pain, and increased handgrip strength. There was a significant difference (p<0.05) between the groups for perceived exertion before and after the intervention. No significant differences were found among the other variables. Conclusion: The physiotherapeutic intervention program improved the quality of life assessed with the SF-36 domains of physical functioning, physical role limitations, and bodily pain, and increased handgrip strength of patients with symptoms of post-COVID-19 syndrome.
RESUMEN
The tribe Serrasalmini is a diverse group with paraphyletic genera and taxonomic uncertainties. Several studies have been carried out in this group of fish in order to understand this problem, including the cytogenetic approach. In this study, three species of a clade of Serrasalmini were characterized cytogenetically - Pristobrycon striolatus, Catoprion absconditus and Pygopristis denticulatus. The three species presented diploid number (2n) equal to 62 chromosomes, of one and two arms, with karyotypic formulas and species-specific fundamental numbers. Heterochromatin is centromeric and terminal (bi-telomeric) in most chromosomes, with a conspicuous interstitial block at pair 1 (m) in all three species. The nucleolar organizer regions were multiple and C-band positive, and their location was confirmed via 18S ribosomal DNA mapping; however, with additional sites. The 5S rDNA was located in interstitial region of long arm of pair 1 (m), in the three species (homeologous). Moreover, we observed synteny between 18S and 5S in the species C. absconditus and P. denticulatus, which, according to fiber-FISH, are interspersed. Thus, the maintenance of 2n (62) evidences the diversification of chromosomal formulas within the clade by non-Robertsonian rearrangements and reflects the paraphyly of the related species.
RESUMEN
Objective: To analyze the effect of the Mobilization With Movement (MWM) of the Mulligan's concept in the perception of nociceptive and neuropathic pain, range of motion (ROM) and joint mobility of individuals with low back pain. Method: This is a randomized and controlled clinical trial, with 30 volunteers with nonspecific low back pain, divided into: Intervention Group (INTG), that received sustained natural apophyseal glides (SNAG) type MWM of the Mulligan's concept; Control Group (CONTG), which received a similar intervention to INTG. Volunteers were assessed using the Numeric Rating Scale for Pain (NRS Pain); the Modified Schober Test (MST) and ROM by goniometry for lumbar spine mobility and Douleur Neuropatique 4 (DN4) questionnaire for assessment of neuropathic and nociceptive pain. Results: INTG showed an increase in lumbar flexion (pre-intervention= 81.21±15.23°; post-intervention= 90.00±19.62°, p< 0.05), mobility of the lumbar spine in MST (pre= 15.33±1.05 post= 16.08±1.02, p< 0.05) and reduction of pain perception by NRS Pain (pre= 5.33±2.26; post= 1.47±2.61 p< 0.05) and in CONTG (pre= 4.07±2.34; post= 2.20±1.93, p< 0.05). Conclusion: The intervention with MWM - SNAGs promoted improved ROM and mobility in flexion of the lumbar spine, associated with reduction from the nociceptive pain in INTG and CONTG.

Conclusão: A intervenção com MWM - SNAGs promoveu melhora da ADM e da mobilidade na flexão da coluna lombar, associada com redução da dor nociceptiva no GINT e no GCONT.
RESUMEN
As próteses parciais removíveis (PPRs) são uma alternativa de tratamento viável na prática clínica para reabilitar arcos parcialmente desdentados. Entretanto, o planejamento dessas próteses e preparo bucal prévio são frequentemente negligenciados. O presente artigo tem como objetivo relatar o caso clínico de uma reabilitação oral com PPRs superior e inferior após abordagem multidisciplinar, de modo a enfatizar as fases de um planejamento criterioso e de preparo prévio dos dentes pilares, visando o sucesso e a longevidade da reabilitação. Paciente do sexo masculino de 57 anos de idade compareceu à clínica da Faculdade de Odontologia de Bauru, Universidade de São Paulo, queixando-se da estética de seu sorriso e de algumas ausências dentárias. O indivíduo utilizava uma PPR provisória inferior insatisfatória e apresentava perda de dimensão vertical de oclusão (DVO). Após o exame clínico, radiográfico e estudo do caso em articulador semi-ajustável, realizou-se o planejamento com abordagens restauradoras, endodônticas, periodontais e protéticas. Após tratamento periodontal, foi realizada endodontia dos elementos 12, 15 e 47, confecção de núcleos e coroas nos dentes 12 e 15, restauração a nível gengival para apoio residual no dente 47, restaurações nos dentes 11, 13, 22, 24 e 44 e, por fim, a confecção das PPRs superior e inferior. A abordagem multidisciplinar utilizada neste caso clínico viabilizou o restabelecimento da DVO e possibilitou o sucesso da reabilitação protética(AU)
Removable partial dentures (RPDs) are a viable treatment alternative in clinical practice to rehabilitate partially edentulous arches. However, the planning of these dentures and prior oral preparation are often neglected. This article aims to report the clinical case of an oral rehabilitation with upper and lower RPDs after a multidisciplinary approach, to emphasize the phases of careful planning and prior preparation of the abutment teeth, aiming at the success and longevity of the rehabilitation. A 57-year-old male patient came to the clinic of the Bauru School of Dentistry, University of São Paulo, complaining about the esthetics of his smile and some missing teeth. The subject was using an unsatisfactory lower provisional prosthesis and had a loss of vertical dimension of occlusion (OVD). After the clinical and radiographic examination and the case study in a semi-adjustable articulator, planning was carried out with restorative, endodontic, periodontal and prosthetic approaches. After periodontal treatment, endodontics were performed on elements 12, 15 and 47, creation of cores and crowns on teeth 12 and 15, restoration at the gingival level for residual support on tooth 47, restorations on teeth 11, 13, 22, 24 and 44 and, finally, the making of the upper and lower PPRs. The multidisciplinary approach used in this clinical case enabled the restoration of the OVD and enabled the success of the oral rehabilitation(AU)

RESUMEN
This study aimed to evaluate the influence of cleft width on dental arch symmetry of children with unilateral cleft lip and palate. Forty-one children were subjected to impression preoperatively (T1; mean age = 0.31 ± 0.07 years) and postoperatively (T2; mean age = 6 .73 ± 1.02 years). Eighty-two digitized dental casts were analyzed by stereophotogrammetry software. The cleft palate width was measured in the anterior (P-P'), middle (M-M'), and posterior (U-U') regions. Also, the following measurements were obtained: anterior intersegment (I-C') and intrasegment (I-C); total intersegment (I-T') and intrasegment (I-T); cleft-side (C'-T') and non-cleft-side (C-T) canine tuberosity. Paired t test and Pearson correlation coefficient were applied (α = 5%). Cleft width had the following means: 10.16 (± 3.46) mm for P-P', 12.45 (± 3.00) mm for M-M', and 12.57 (± 2.71) mm for U-U'. In the longitudinal analysis, I-C' had a significant reduction, while the other measurements significantly increased (p < 0.001). Asymmetry was verified in the following analyses at T1: I-C' vs. I-C and I-T' vs. I-T (p < 0.001); at T2, only in I-C' vs. I-C (p < 0.001). At T1, P-P' vs. I-C' (r = 0.722 and p < 0.001), P-P' vs. I-T' (r = 0.593 and p < 0.001), M-M' vs. I-C' (r = 0.620 and p < 0.001), and M-M' vs. I-T' (r = 0.327 and p < 0.05) showed a positive and significant correlation. At T2, there was a correlation between M-M' and I-C' (r = 0.377 and p < 0.05). In conclusion, the anterior and middle cleft widths influenced palatal asymmetry in the first months of life, while middle width influenced residual asymmetry.

Brazil has one of the largest forest areas on the planet and the potential for the emergence of new diseases. In turn, orofacial clefts, especially cleft lip and or palate (CL/P), are characterized as congenital malformations and may be associated with genetic and environmental factors. The present study aimed to investigate in silico the flavivirus's potential to emerge in Brazil as an etiology of CL/P. A scoring method was created based on literature and nucleotide similarity analysis. An integrative analysis of the literature was performed to answer the questions through the databases PubMed/MEDLINE, SciELO, LILACS, and Google Scholar to have a more significant number of results. The software Basic Local Alignment Search Tool-BLAST 2.12.0, through the Genomic + Transcript Databases (Human Genomic plus Transcript Human G+T), was selected to find similarities with human sequences associated with CL/P. The viral sequences used were obtained from the National Center for Biotechnology Information Virus-NCBI Virus, in which only complete and referential genomes were selected. The flavivirus that emerged in Brazil and presented a high potential to cause CL/P was the Iguape virus strain (species Aroa virus ), followed by the Cacipacore virus and the Rocio virus strain (species Ilheus virus ) with medium potential to cause CL/P. In conclusion, we suggest among the virus evaluated that the Iguape virus presented a high potential of causing CL/P. As prevention, the control of arthropods and the hospital diffusion on viral dynamics, mainly in the CL/P context and other congenital malformations, are indicated.

The objective of this systematic review was to identify the available scientific evidence on bone substitutes (BSs) compared with autogenous bone grafts (ABGs) for regeneration of horizontal bone resorption in the anterior maxillary alveolar process, aiming at rehabilitation with endosseous implants. This review was performed according to the PRISMA guidelines (2020) and registered in the database PROSPERO (CRD: 42017070574). The databases searched were PUBMED/MEDLINE, EMBASE, SCOPUS, SCIENCE DIRECT, WEB OF SCIENCE, and CENTRAL COCHRANE, in the English language. The Australian National Health and Medical Research Council (NHMRC) and Cochrane Risk of Bias Tool were used to assess the study's quality and risk of bias. A total of 524 papers were found. After the selection process, 6 studies were selected for review. A total of 182 patients were followed for a period of 6 to 48 months. The mean age of patients was 46.46 years, and 152 implants were installed in the anterior region. Two studies achieved a reduced graft and implant failure rate, whereas the remaining 4 studies had no losses. It may be concluded that the use of ABGs and some BSs is a viable alternative for the rehabilitation with implants in individuals with anterior horizontal bone loss. However, additional randomized controlled trials are warranted due to the limited number of papers.

Objetivo: descrever os indicadores de morbimortalidade da covid-19 em crianças e adolescentes no estado do Ceará. Métodos: trata-se de um estudo observacional, analítico, do tipo transversal que avaliou dados secundários referente às notificações de covid-19, em crianças e adolescentes, no estado do Ceará, dos anos de 2020 a 2022. A coleta de dados ocorreu por meio da base de dados da Integração das Informações da Secretaria da Saúde do Estado do Ceará. Para o processamento dos dados, utilizou-se o Microsoft Excel, o qual foi organizado em tabelas e analisado por meio de estatística descritiva. A pesquisa não necessitou de aprovação em Comitê de Ética em Pesquisa. Resultados: observou-se, tanto para o sexo feminino quanto para o masculino, que o ano de 2021 obteve o maior número de casos notificados, confirmados e óbitos, e as faixas etárias mais acometidas foram as de zero a quatro anos e adolescentes de 15 a 19 anos. Para os indicadores de incidência, o sexo feminino teve maior incidência de casos confirmados na faixa etária de 15 a 19 anos. Os indicadores de mortalidade estiveram maiores entre as crianças de zero a quatro anos do sexo masculino, nos anos 2021 e 2022. Conclusões: os achados deste estudo reforçam que alguns grupos podem ter maior risco de desfechos ruins. O que torna necessário identificar fatores associados a resultados insatisfatórios em crianças e adolescentes com covid-19.
Objective: to describe the morbidity and mortality indicators of covid-19 in children and adolescents in the State of Ceará. Methods this is an observational, analytical, cross-sectional study that evaluated secondary data regarding notifications of covid-19 in children and adolescents in the state of Ceará from 2020 to 2022. Data collection took place through the database of the Integration of Information of the Secretariat of Health of the State of Ceará. Microsoft Excel was used for data processing, they were organized in tables and analyzed using descriptive statistics. The research did not require approval from the Research Ethics Committee. Results: it was observed, for both females and males, that the year 2021 had the highest number of reported, confirmed cases and deaths, and the most affected age groups were those from zero to four years and adolescents from 15 to 19 years old. For the incidence indicators, females had a higher incidence of confirmed cases in the age group of 15 to 19 years. Mortality indicators were higher among male children aged zero to four years in the years 2021 and 2022. Conclusions: The findings of this study reinforce that some groups may be at greater risk of poor outcomes. This makes it necessary to identify factors associated with unsatisfactory outcomes in children and adolescents with covid-19.

This in silico study aims to investigate flaviviruses as an environmental factor in the etiology of nonsyndromic cleft lip and/or palate (CL/P).A scoring method with 7 topics-disease, transplacental passage, tropism, cellular damage, reported case, analysis of genome similarity, and transcriptome between virus and host, was created based on literature and in silico experimentation. Viral genomes of NCBI virus were obtained and BLAST 2.12.0 was applied for the similarity analysis, adjusted to search for only human sequences related to CL/P with the statistical threshold defined for E-value ≤1.Flaviviruses with high potential to cause CL/P were: serotypes 2, 3, and 4 of the Dengue virus and lineage 2 of the West Nile virus, while the Yellow Fever virus, Japanese encephalitis virus, Tick-borne encephalitis virus, and Saint Louis encephalitis virus presented with medium potential to cause CL/P. As for the Zika virus, even strains associated with microcephaly showed only medium potential.Dengue virus and West Nile virus presented with high potential to act as environmental factors in the etiology of CL/P.
