Comparative Evaluation of Clinical Efficacy of Diode LASER and Cryosurgery for Gingival Pigmentation: A Split-Mouth Randomized Clinical Study

ABSTRACT Objective: To compare and evaluate the clinical efficacy of diode laser and cryosurgery for treating melanin pigmentation of gingiva. Material and Methods: A total of twenty-five subjects with physiological gingival pigmentation on the facial aspect of both maxillary and mandibular anterior arches (50 sites), both male and female, with an average age ranging from 18-35 years, participated in the study. The sites were randomly divided into Group I: depigmentation by Laser and Group II: depigmentation by Cryosurgery. The following parameters were assessed for the evaluation of treatment results: Melanin Oral Pigmentation Index (PI), Visual Analogue Scale (VAS) for pain evaluation and Healing index (HI). The data collected was statistically evaluated. Results: On intergroup comparison, there was no statistical difference in the score from baseline (p>0.05); however, a statistically significant difference was seen at the end of 1 year (p<0.05). Moreover, 57-60% of arches showed recurrence of pigmentation in the laser group whereas; only 12.7-17% recurrence was seen in the cryosurgery group at the end of the first year. Conclusion: Treatment of gingival hyperpigmentation with laser and cryosurgery shows a marked improvement of gingival pigmentation in both groups, but the cryosurgery depigmentation sites showed more sustainability.

Estudo comparativo de zumbido e aptidão cardiorrespiratória entre pessoas pós-COVID-19 / Comparative study of tinnitus and cardiorespiratory fitness among people post COVID-19

RESUMO Objetivo Verificar a relação entre zumbido e aptidão cardiorrespiratória em pessoas após COVID-19. Métodos Estudo transversal com amostra de pessoas pós-COVID -19 que responderam à Escala Visual Analógica para zumbido e questionário padronizado contendo dados sobre internação e zumbido. Para avaliar a aptidão cardiorrespiratória, utilizou-se a avaliação clínica e o Teste de Bruce para mensurar o consumo de oxigênio diretamente (via analisador de gases, com utilização do consumo pico de oxigênio - VO2pico). Resultados Participaram 192 pessoas, com média de idade de 47,8 ± 12,6 anos. A prevalência de zumbido autorreferido foi de 27,1% (n = 52). Dos 52 pacientes com zumbido, 27 iniciaram com o sintoma durante ou após o diagnóstico de COVID-19. Houve diferença significativa para o VO2pico absoluto entre os grupos com e sem zumbido (p = 0,035), sendo que o grupo com zumbido apresentou os menores valores; o tamanho do efeito foi pequeno. Não houve correlação entre os escores da Escala Visual Analógica para o zumbido e os valores de VO2pico absoluto e relativo (p > 0,05). Conclusão Houve diferença estatisticamente significativa entre as queixas de zumbido e o VO2pico nas pessoas após a COVID -19, sendo que o grupo com zumbido apresentou o VO2pico absoluto menor do que o grupo sem zumbido. Nos pacientes com zumbido, também foi encontrado VO2pico absoluto e relativo menor para as mulheres, além do VO2pico relativo menor para os hipertensos e obesos.

ABSTRACT Purpose To verify the relation between tinnitus and cardiorespiratory fitness among people after COVID-19. Methods Cross-sectional study with a sample of people post Covid-19 who responded to the Visual-Analog Scale for tinnitus and standardized questionnaire containing data on hospitalization and tinnitus. To evaluate cardiorespiratory fitness, it used the clinical assessment and Bruce test to measure oxygen consumption directly (via gas analyzer, using peak oxygen consumption - VO2peak). Results In total, 192 participants were assessed, with a mean age of 47.8 ± 12.6 years . The prevalence of self-reported tinnitus was 27.1% (n = 52). Of these 52 patients with tinnitus, 27 people started with the symptom during or after the diagnosis of COVID-19. There was a significant difference for the absolute VO2peak and the groups with and without tinnitus (p = 0.035): the tinnitus group showed the lowest values, the effect size was small. There was no correlation between the scores of the Visual-Analog Scale for tinnitus and the absolute and relative VO2peak (p > 0.05). Conclusion There was a statistically significant difference between tinnitus complaints and the VO2peak among people post COVID-19, with the tinnitus group having a lower absolute VO2peak than the non-tinnitus group. In tinnitus patients, we also found lower absolute and relative VO2peak for women, in addition to lower relative VO2peak for hypertensive and obese patients.

Introduction: Appropriate pain control is a crucial and necessary challenge to address in the surgical field, since it would produce a great impact patient recovery. Objective: To assess the effect of a nursing intervention applied during the perioperative period for pain control in the adult patient in the immediate postoperative period. Methods: Quantitative and quasiexperimental study carried out with two groups, an experimental and a control group, of adults operated on in the surgical room of a health institution in Bucaramanga, Colombia, in the first semester of 2017. The universe consisted of 3240 patients, while the calculated sample was 120. The intervention consisted in three phases, framed within the theory of unpleasant symptoms. The visual analog scale was used to assess pain. Descriptive, bivariate and multiple analyses were performed. Betas were calculated with linear regression models and using the scores of the pain scale at ten to twenty and thirty minutes; as well as at one to one and half hours, and two hours. Results: The groups presented similar characteristics: in the experimental group, the scores of the pain scale decreased at ten minutes by 0.98 (95 percent CI: -2.0; 0.02); at one hour, by 0.77 (95 percent CI: -1.60; 0.05; at one and a half hours, by 0.71 (95 percent CI: -1.13; -0.12); and at two hours, by 0.60 (95 percent CI: -1.09; -0.10). Conclusions: The nursing intervention in the perioperative period, beyond the administration of analgesics, is fundamental to modify responses, as referred by Swanson's theory, unpleasant symptoms and their negative effects are improved or controlled; in this case, postoperative pain(AU)

A Randomized Triple-Blind Clinical Trial of the Effect of Low-Level Laser Therapy on Infiltration Injection Pain in the Anterior Maxilla

Abstract Objective: To evaluate the level of pain experienced during infiltration anesthesia of the anterior maxilla following low-level laser therapy (LLLT) with 810-980 nm wavelengths. Material and Methods: In the current triple-blind clinical trial, 84 patients received a total of 168 infiltration anesthesia injections (1.8 mL of 2% lidocaine plus 1:100,000 epinephrine) in the anterior maxilla. Each patient received two injections into the buccal mucosa of the right and left central incisors with a two-week interval. One injection was performed after LLLT, while the other injection was administered conventionally without laser. The pain level was measured immediately after injection using a visual analog scale (VAS). Results: There was a significant difference in the pain level experienced with and without LLLT, such that the mean pain score following LLLT was significantly lower than that without LLLT (p<0.05). No significant difference was found in the pain level between laser and no laser groups in males, but the difference in this regard was significant in females (p<0.05) and female patients experienced a significantly lower level of pain following LLLT. Conclusion: The low-level laser therapy can be successfully used to decrease the level of pain experienced during infiltration anesthesia of the anterior maxilla (AU).

Smile Arc Esthetics in Middle-Aged Man from the Layperson's Perspective Via Eye-Tracking

Abstract Objective: To evaluate the perceptions of smile esthetics associated with variations in the vertical plane of the maxillary incisors in the smile arc using eye-tracking software. Material and Methods: An image of a 59-year-old Caucasian male model was adapted and edited to make three changes in the vertical plane, simulating a convex, straight, and reverse smile arc. Four areas of interest were inserted at the right and left eyes, nose, and mouth. Forty laypeople raters between 18 and 45 years of age participated of the study. Eye-tribe hardware and Ogama software were used to perform eye-tracking. Attractiveness and age-perception questions were also incorporated into the study. ANOVA test and Pearson's correlation coefficient, at p < 0.05. Results: The most observed AOI in images with convex, straight, and reverse smiles, as assessed using heatmaps and point maps, was the mouth, followed by the right eye. A significant difference for the eye (p=0.02) was found when comparing convex and reverse smiles, whereas a significant difference for the mouth was observed between the straight and reverse smiles (p=0.03). Conclusion: Convex and straight smile arcs were associated with equal levels of attractiveness; the reverse smile was less attractive. No significant difference was noticed regarding age perception and the smile arcs. However, the reverse smile recorded a more complete fixation time.

Psychosocial concerns predict longitudinal trajectories of distress in newly diagnosed cancer patients

INTRODUCTION@#Unmet psychosocial concerns are associated with emotional distress among cancer patients. This longitudinal study aimed to identify specific psychosocial concern profiles and trajectories of emotional distress, and examine their association among newly diagnosed adult cancer patients across the first year of diagnosis.@*METHODS@#Adult patients aged 21-64 years were screened to determine their eligibility for this study. Psychosocial concerns and psychological distress were measured using the Problem List and the Distress Thermometer, respectively (n = 221). Latent transition mixture analysis was used to determine specific psychosocial concern profiles and trajectories of emotional distress, and examine associations with adjustments made for demographic and medical variables.@*RESULTS@#Two classes of psychosocial concerns were identified: low (81%) and high (19%) concerns. Two trajectories of distress were identified: low stable (69%) and high stable (31%) trajectories. Patients in the high concerns class were significantly more likely to demonstrate the high stable trajectory of distress.@*CONCLUSION@#Our findings highlight the importance of concurrent assessment of multiple psychosocial concerns and screening of emotional distress throughout a cancer patient's treatment journey. Such assessments can effectively guide interventions to address individual concerns and alleviate emotional distress among newly diagnosed cancer patients.

Evaluación de la efectividad y satisfacción de las pacientes tras miomectomía histeroscópica en consulta / Evaluation of effectiveness and patient satisfaction of hysteroscopic myomectomy in office

OBJETIVO: Analizar la efectividad de las miomectomías histeroscópicas en consulta realizadas con minirresector y conocer si hay factores relacionados con el grado de satisfacción de las pacientes. MÉTODO: Estudio observacional, transversal y prospectivo, de mujeres sometidas a miomectomía histeroscópica en consulta durante el año 2018. Las pacientes recibieron medicación para la preparación cervical, analgesia oral y anestesia paracervical. La miomectomía se realizó con un minirresector de 5.8 mm. Se registraron el tiempo y el dolor en una escala visual analógica (EVA) durante la entrada y la resección, así como la satisfacción de las pacientes a los 3 meses con el cuestionario validado CSQ-8. RESULTADOS: El estudio incluyó 59 pacientes. El tiempo medio de entrada fue menor de 1 minuto (47,93 segundos) y el de resección fue de 13,51 minutos. El dolor referido por las pacientes en la EVA durante la entrada y la resección puntuó en torno a 3 y 4, respectivamente. Se consiguió un 74.6% de resecciones completas de los miomas y la puntuación media de satisfacción de las pacientes fue de 27.17. La resección completa del mioma se asoció con una mayor satisfacción total de las pacientes. CONCLUSIONES: La miomectomía histeroscópica en consulta llevada a cabo con un minirresector de 5.8 mm con analgesia paracervical obtiene buenos resultados clínicos, con buena satisfacción de las pacientes. Esta última se relaciona con una resección completa del mioma, sin que influyan el tiempo necesario para su exéresis ni el dolor.

OBJECTIVE: To analyze the effectiveness of hysteroscopic myomectomy in office performed with mini-resectoscope, and to know if there is any variable related with patient satisfaction. METHOD: Observational and prospective transversal study, which included all women who underwent a hysteroscopic myomectomy in office in 2018. Patients received drugs for cervical preparation and pain management, as well as paracervical block. We used the 5.8 mm mini-resectoscope. We kept record of time and AVS pain during entrance and resection, as well as patient satisfaction 3 months after the procedure using the CSQ-8. RESULTS: The study included 59 patients. Mean entrance time was less than 1 minute (47.93 seconds), while mean resection time was 13.51 minutes. AVS pain during entrance and resection was around 3 and 4, respectively. We achieved 74.6% rate of complete resection. Mean patient satisfaction rate was 27.17 points. We found that a complete myoma resection is related to higher patient satisfaction. CONCLUSIONS: Hysteroscopic myomectomy in office performed with the 5.8 mm mini-resectoscope, using cervical block, achieves good clinical results and a good patient satisfaction. Patient satisfaction is associated with a complete resection of the myoma, without any influence of pain experienced or time required.

Avaliação clínica do uso de antibióticos em cirurgias para instalação de implantes dentários: um ensaio clínico randomizado, triplo cego e controlado / Clinical evaluation of the use of antibiotics in surgeries to install dental implants: a randomized, triple-blind, controlled clinical trial

Objetivo: avaliar clinicamente por meio de um ensaio clínico controlado, randomizado e triplo cego, 2 regimes farmacológicos de profilaxia antibiótica, em pacientes submetidos a instalação de implantes dentários de dois estágios, quanto a dor, infecção e perda de implantes. Materiais e métodos: Um total de 61 pacientes receberam 115 implantes dentários. A coleta dos dados foi realizada por um examinador calibrado e cego nos seguintes períodos de acompanhamento pós-operatório: T1 (7 dias), T2 (14 dias), T3 (30 dias) e T4 (120 dias). A randomização foi realizada por meio da função aleatório do Microsoft Excel® (2013), que dividiu os grupos de forma aleatória e os pacientes foram alocados de acordo com a lista gerada pelo programa. Os sujeitos da pesquisa foram divididos em 3 grupos: grupo 1 (G1) formado por 21 pacientes que não utilizaram profilaxia antibiótica, o grupo 2 (G2) formado por 20 pacientes que fizeram uso da profilaxia antibiótica pré-operatória com amoxicilina 1 g por via oral 1 hora antes do procedimento e o grupo 3 (G3), com 20 pacientes que utilizaram profilaxia antibiótica pré-operatória com amoxicilina 1g via oral 1 hora antes do procedimento e manutenção do antibiótico, sendo 500 mg de amoxicilina por 05 dias a cada 08 horas. A variável dor foi analisada utilizando-se de uma escala visual analógica- EVA e do número de analgésicos ingeridos. A infecção foi considerada quando na presença de pus e fístula. Além disso, no tempo T4 foi realizado a reabertura do implante para avaliação do sucesso da osseointegração primária, considerando ausência de mobilidade e dor quando da troca do parafuso de cobertura pelos cicatrizadores. A dor (EVA e número de analgésicos) foi analisada por meio do teste Kruskall Wallis e o pós-teste (Post hoc de Dunn). A infecção foi analisada com o teste Exato de Fisher e a falha, descritivamente. O nível de significância foi estabelecido em 5%, com intervalo de confiança de 95%. Resultados: A análise da dor pós-operatória evidenciou melhores resultados nos grupos que utilizaram antibiótico (G2 e G3) no acompanhamento T1 (7 dias), com os pacientes sentindo menos dor (Teste de Kruskall Wallis- p < 0,05). A avaliação entre os grupos G2 e G3 também evidenciou diferenças (Post hoc de Dunn- p < 0,05) com superioridade para G3. Nos demais períodos não houve diferenças significativas. A infecção esteve presente nos grupos G1 (2 casos) e G3 (2 casos), porém não houve diferença estatística entre os grupos (Teste Exato de Fisher- p > 0,05) com evolução para perda (falha) de dois implantes, um no grupo G1 e outro no grupo G3. Conclusões: Os resultados preliminares de estudo evidenciaram melhores resultados quanto a dor, nos pacientes que utilizaram antibiótico profilático, mas não conseguiu demonstrar superioridade quanto a infecção e perda do implante quando comparado ao grupo sem uso de antibióticos. Dessa forma, baseado nos resultados do presente estudo, considerando um número máximo de 4 implantes por procedimento, em pacientes saudáveis, sem procedimentos adicionais, o uso de antibióticos embora tenha melhorado a dor no pós-operatório imediato, não demonstrou benefício em relação a diminuição dos índices de infecção e falha dos implantes (AU).

Objective: conduct a randomized, triple-blind, controlled test to clinically assess 2 pharmacological treatments of antibiotic prophylaxis, in patients submitted to a two-stage dental implant procedure, in terms of pain, infection and implant failure. Materials and methods: A total of 61 patients received 115 dental implants. Data collection was conducted by a blind calibrated examiner during the following postoperative follow-up periods: T1 (7 days), T2 (14 days), T3 (30 days) and T4 (120 days). Randomization was performed using the random function of Microsoft Excel® (2013), which randomly divided patients according to the list generated by the program. The study subjects were divided into 3 groups: group 1 (G1) consisting of 21 patients who did not use an antibiotic prophylaxis, group 2 (G2), with 20 patients who used preoperative antibiotic prophylaxis (1 g of amoxicillin) applied orally 1 hour before the procedure and group 3 (G3), with 20 patients who used preoperative antibiotic prophylaxis (1g of amoxicillin) applied 1 hour before the procedure, maintaining the antibiotic, consisting of 500 mg of amoxicillin, for 5 days every 8 hours. Variable pain was analyzed using a visual analog scale (VAS) and the number of analgesics taken. Infection was considered by the presence of pus and fistula. The implant was reopened at time T4 to evaluate the success of primary osseointegration, considering the absence of mobility and pain while replacing the cover screw with a healing screw. Pain (VAS and number of analgesics) was analyzed using the Kruskal-Wallis and Dunn's post hoc tests. Infection was analyzed with Fisher's Exact test and failure described. A 5% significance level was established, with a 95% confidence interval. Results: Analysis of postoperative pain showed better results in the groups that used antibiotics (G2 and G3) at follow-up T1 (7 days), with patients experiencing less pain (Kruskal Wallis, p < 0.05). Intergroup assessment also demonstrated differences (Dunn's post hoc, p < 0.05), being higher in G3, but there were no significant differences in the other periods. Infection was present in group 1 (2 cases) and G3 (2 cases), with no significant intergroup differences (Fisher's Exact test, p > 0.05), with a loss (failure) of two implants: one in G1 and the other in G3. Conclusions: The preliminary results of the study revealed better pain results in patients who used prophylactic antibiotics, but was not superior in relation to infection or implant failure when compared to the group that did not use antibiotics. Thus, based on the results of the present study, considering a maximum of 4 implants per procedure, in healthy patients with no additional procedures, although antibiotics improved pain in the immediate postoperative, they did not decrease infection indices or implant failure (AU).

Estimulação elétrica nervosa transcutânea interativa e convencional em mulheres com dismenorreia primária / Interactive and conventional transcutaneous electrical nerve stimulation in women with primary dysmenorrhoea

A dismenorreia primária é uma dor na região inferior do abdômen, antes ou durante a menstruação e independente de patologias pélvicas. Tratamentos fisioterapêuticos são alternativas para a melhora dos sintomas, dentre esses recursos, a estimulação elétrica nervosa transcutânea (TENS). O objetivo deste estudo foi comparar o efeito terapêutico e analgésico da TENS interativa e convencional na dor secundária à dismenorreia primária. A aplicação da TENS, em ambos os grupos, foi realizada no primeiro dia do período menstrual por 35 minutos. Na TENS interativa todas as voluntárias optaram pelos seguintes parâmetros: frequência de 250 Hz, duração de pulso de 25 µs e intensidade conforme nível sensorial, sendo essa ou a duração do pulso reajustado, a cada 5 minutos, conforme houvesse necessidade. Na TENS convencional foi utilizado os seguintes parâmetros: frequência de 100 Hz, duração de pulso de 50 µs e com a intensidade conforme grupo anterior. A análise estatística foi realizada por meio do software GraphPadPrism®, versão 5.0, sendo empregado o teste t de Student e com nível de significância de p < 0,05. Obteve-se como resultado uma redução da dor entre as participantes de ambos os grupos logo após o tratamento. Porém não houve diferença na analgesia promovida pelos dois métodos de tratamento. (AU)

Primary dysmenorrhea (PD) is a lower region of the abdomen pain, before or during menstruation and independent of pathologies. Physical therapy treatments are alternatives to improve symptoms, among these resources, transcutaneous electrical nerve stimulation (TENS). The aim of this study was to compare the therapeutic and analytical effect of interactive and conventional TENS in high school in PD. The application of TENS, in both groups, was performed on the first day of the menstrual period for 35 minutes. In the interactive TENS all the volunteers chose the following parameters: frequency of 250 Hz, pulse duration of 25 µs and intensity according to sensory level, whether this or the duration of the readjustment of the pulse, every 5 minutes, according to the need for use. In conventional TENS, the following parameters were used: frequency of 100 Hz, pulse duration of 50 µs and intensity according to the previous group. A statistical analysis was performed using the GraphPadPrism® software, version 5.0, being employed Student's test with a significance level of p < 0.05. The result is a reduction in pain among participants in both groups right after treatment. However, there was no difference in the analgesia promoted by the two treatment methods. (AU)

Evaluación de la obstrucción nasal por métodos subjetivos y pico flujo inspiratorio nasal en niños y adolescentes con rinitis crónica / Assessment of nasal obstruction by subjective methods and peak nasal inspiratory flow in children and adolescents with chronic rhinitis

Introducción. La obstrucción nasal (ON) es el síntoma más molesto de la rinitis crónica (RC). Los estudios que correlacionaron métodos subjetivos y objetivos de ON realizados en niños y adultos produjeron resultados contradictorios. Objetivos. Analizar la correlación entre escalas subjetivas de ON con determinaciones de pico flujo inspiratorio nasal (PFIN) y comparar la valoración subjetiva de la ON y el PFIN en niños según su edad. Población y métodos. Participaron pacientes con RC. Se estimó la correlación entre la evaluación subjetiva de la ON mediante una escala visual análoga (ON-EVA, por su sigla en inglés) y la Escala de evaluación de los síntomas de obstrucción nasal (NOSE, por su sigla en inglés) y medición del flujo aéreo nasal pre- y posvasoconstrictor, mediante PFIN. Se analizaron las diferencias entre los grupos de 8 a 11 años y los de 12 a 15 años para la valoración subjetiva de la ON y PFIN. Resultados. Se incluyeron 79 pacientes entre 8 y 15 años. No se comprobó correlación entre ON-EVA y PFIN antes y después del vasoconstrictor (r = -0,19; p = 0,11 y r = -0,18; p = 0,15 respectivamente) ni entre NOSE y PFIN basal (r = -0,23; p = 0,07). Hubo diferencias en el PFIN entre niños de 8-11 años y 12 a 15 años (p = <0,0001), pero no se demostraron diferencias en la percepción subjetiva por ON-EVA (p = 0,7591). Conclusión. No se demostró correlación entre puntajes subjetivos de ON y PFIN en niños y adolescentes con RC. Los niños mayores perciben menos la ON que los de menor edad. Las escalas subjetivas de ON no reemplazan su medición con PFIN en pacientes con rinitis.

Introduction. Nasal obstruction (NO) is the most irritating symptom of chronic rhinitis (CR). The results of studies that correlated subjective and objective methods of NO in children and adults were contradictory. Objectives. To analyze the correlation between subjective NO scales and peak nasal inspiratory flow (PNIF) measurements and compare the subjective NO assessment and PNIF in children by age. Population and methods. Participants were patients with CR. The correlation between the subjective NO assessment using a visual analog scale (NO-VAS) and the Nasal Obstruction Symptom Evaluation (NOSE) and nasal airflow measurement pre- and post-vasoconstrictor administration using the PNIF was estimated. The differences in the subjective NO assessment and PNIF between children aged 8-11 years and 12-15 years were analyzed. Results. A total of 79 patients aged 8-15 years were included. No correlation was established between the NO-VAS and the PNIF before and after vasoconstrictor administration (r = -0.19; p = 0.11 and r = -0.18; p = 0.15 respectively) or between the NOSE and the baseline PNIF (r = -0.23; p = 0.07). Differences were observed in the PNIF between children aged 8-11 years and 12-15 years (p = < 0.0001), but there were no differences in the subjective perception assessed with the NO-VAS (p = 0.7591). Conclusion. No correlation was demonstrated between the subjective NO score and the PNIF in children and adolescents with CR. Older children have a lower perception of NO than younger ones. Subjective NO scales cannot replace the PNIF measurement in patients with rhinitis

Introduction: The association between depressive symptoms and pain is evidenced, so they must be treated together. Objective: To determine the relationship between depressive symptoms and chronic back pain in patients who start rehabilitation. Material and methods: An observational, prospective and cross-sectional study was conducted in 118 patients with chronic back pain who started rehabilitation. The pain was measured using the Visual Analog Scale and depressive symptoms were measured with the Beck Depression Inventory-II. Results: The patients presented an average pain of 6,69 ± 1,98, with moderate levels of intensity (52,5 percent) and lumbar location (55,1 percent); the longest time duration ranged from 1 to 3 years (54,2 percent). Depressive symptoms had an average score of 19,13 ± 10,62; they were analyzed in two groups: minimum level of symptoms (0-13 points) and risk (14-63 points) including mild, moderate and severe levels (66,9 percent). The relationship between depressive symptoms and chronic back pain was significant; that is, the higher the level of pain, the greater the presence of symptoms. In the case of severe level of pain, the mild/moderate/severe symptoms were 80,9 percent (p = 0,03); 73,3 percent for females (p = 0,02); concerning marital status, 93,8 percent were separated/widowed (p = 0,04) and 100 percent had no levels of education (p = 0,03). Conclusions: Depressive symptoms are related to chronic back pain; the higher the level of pain, the greater the presence of depressive symptoms. It is also associated with the female sex, separated or widowed persons and persons without any education(AU)

Aplicação do refinamento das regras de ligação da CIF à Escala Visual Analógica e aos questionários Roland Morris e SF-36 / Application of the refinements of ICF linking rules to the Visual Analogue Scale, Roland Morris questionnaire and SF-36

Resumo A Escala Visual Analógica (EVA), o Questionário de Incapacidade de Roland Morris (RMDQ) e Questionário de Qualidade de Vida SF-36, amplamente utilizados, tiveram seu conteúdo conectado à CIF por regras propostas em 2002 e 2005. Em 2016 foram refinadas e ainda não foram aplicadas. Aplicar as regras de conexão de conteúdo refinadas para os instrumentos EVA, RMDQ e SF-36. Dois profissionais de saúde identificaram os conceitos significativos e vincularam às categorias mais específicas da CIF, um terceiro arbitrou divergências. O grau de concordância foi dado pelo coeficiente kappa. Houve alto grau de concordância (Kappa=0,93 p<0,001). O conceito principal da EVA foi conectado à categoria b280, os 24 conceitos principais do RMDQ, à categoria b28013 e os 27 adicionais a outras categorias. O SF-36 teve 36 conceitos principais e 30 adicionais identificados, do total, 17 não foram definíveis pela CIF. Dos conceitos conectados dos 3 instrumentos 39 referem-se à Funções do Corpo, 57 à Atividades e Participação e 4 à Fatores Ambientais. O refinamento das regras propiciou mais clareza no processo de identificar, relacionar o conteúdo dos instrumentos à CIF e expor os resultado e aumentou o número de conceitos identificados e categorias contempladas pelos instrumentos.

Abstract The Visual Analogue Scale (VAS), Roland Morris Disability Questionnaire (RMDQ), Short Form Health Survey (SF-36) are broadly used and had their content linked to ICF by the linking rules of 2002 and 2005. In 2016 were refined and were not applied yet. To apply the refinements of ICF linking rules to VAS, RMDQ, and SF-36. Two health professionals identified the meaningful concepts and linked to the most precise ICF categories and a third triggered in divergences. The degree of agreement was calculated by kappa statistic. There was almost perfect agreement (Kappa=0.93 p<0,001). The main concept of VAS was linked to ICF category b280, the 24 main concepts of RMDQ linked to b28013, and 27 additional linked to other categories. The SF-36 had 36 main concepts and 30 additional concepts identified which 27 were definable by the ICF and 17 do not. From the total of ICF linked concepts, 39 refer to Body Functions, 57 to Activities and Participation and 4 to Environmental Factors. The refinements of linking rules propitiated more clarity in the process to identify, to link instruments content with ICF and to expose the results. Thus, increased the number of identified and linked concepts as well as the categories in the instruments.

Evaluation of Masticatory Performance and Patient Satisfaction Before and After Posterior Implant Restoration

ABSTRACT Objective: To evaluate the improvement in masticatory performances two weeks after posterior implant restoration. Material and Methods: Nine patients with missing first and second molars were included in the study. Masticatory performances were evaluated using subjective and objective methods utilizing color-changeable chewing gum and the visual analog scale (VAS) assessment. The subjects were asked to chew the color-changeable chewing gums before and two weeks after the posterior implant restoration. Their expectations regarding aesthetics and function were verified on the VAS before implant placement. Additionally, the VAS was used for the posttreatment completion rating two weeks after the implant restoration. Results: Significant differences in masticatory performance were noted at baseline (before implant posterior restoration) and two weeks after implant restoration (p<0.05). The posttreatment aesthetic and functional expectations ratings significantly exceeded the expectations (p<0.05). Conclusion: Masticatory performances were improved two weeks after implant restoration. In addition, the significant posttreatment ratings of the patients exceeded their initial expectations. In particular, patients with poor masticatory functions demonstrated significant improvements and satisfaction following implant restoration compared to those with good mastication. These findings indicate that a posterior implant restoration can increase the masticatory performance.

Odontogenic Maxillofacial Infections in a High-level Hospital: Orofacial Pain and Related Conditions

ABSTRACT Objective: Odontogenic infection is a common condition in America; the aim of this research was to determine the profile of odontogenic maxillofacial infections and to identify the link between these and the pain felt by patients admitted to the emergency dental service of the Hernân Henriquez Aravena Hospital in Temuco, Chile. Methods: A cross-sectional, double-blind study analysed 49 individuals admitted for emergency dental care. Included were admissions associated with odontogenic infection identified by clinical examination, establishing a relation to pain through a survey. The diagnosis was made clinically using the fascial spaces involved in the infection, presence of self-medication prior to admission, need for surgical treatment and the patient 's systemic conditions. The data were analysed using descriptive statistics, Chi-squared, ANOVA, considering a value of p < 0.05 as significant. Results: The average pain level measured by visual analogue scale (VAS) in emergency admission was 8.1. There was no association between the diagnosis (pulp infection, periodontal infection or pericoronitis) and the VAS (p = 0.078), but there was association between age and the diagnosis (p = 0.022), and the VAS was associated with pain compared to other types of pathologies or traumas (p = 0.011). Conclusion: Odontogenic infection is frequent and linked to age and high-pain values. New public policies should be adopted based on these results. New studies are needed to assess new variables associated with these pathologies.

Revisión sistemática de la literatura sobre la evaluación del proceso de la masticación / Systematic Review Of The Literature On The Evaluation Of The Chewing Process

El objetivo del presente estudio fue presentar una revisión sistemática de la literatura relacionada con los estudios que aborden los métodos de evaluación de la masticación y sus características principales. Como estrategia de investigación se realizó en las bases de datos PubMed, Web Of Science, Medline, SciELO y Lilacs desde 2006 al 2020. Como criterios de selección se escogieron todos los estudios disponibles, sin restricción de idioma; de los últimos 14 años; cuyos participantes no presentaron alteraciones neurológicas ni psiquiátricas. Fueron analizados a partir de su relación con el objeto del presente estudio. Las palabras clave utilizadas en la búsqueda de los artículos fueron identificados en los Descriptores en Ciencias de la Salud (DEDS) siendo las siguientes: "Evaluation", "Mastication", "Masticatory Muscles", "Masseter Muscle" y "Temporal Muscle". Utilizando también OR y AND como operadores lógicos. Se encontró 1311 estudios en las bases de datos investigadas, después de la revisión fueron eliminados 1278 y elegidos 33 artículos; y considerándose sólo 21 artículos según criterios de selección y objetivo. Todos los artículos revisados obtuvieron un alto grado de evidencia (nivel I) luego de realizar una evaluación crítica de la evidencia científica, determinando que todos los artículos evaluados fueron catalogados como estudios clínicos aleatorizados y con diseños experimentales. Siendo excluidos los estudios longitudinales, con individuos con patologías. Se concluye que el método que se utiliza mayormente es la evaluación clínica fonoaudiológica, mediante observación y palpación de musculatura orofacial, seguido de electromiografía de superficie, electrognatografía y la escala analógica visual para la saciedad. Las características observadas fueron, número de ciclos de masticación, velocidad de la masticación, porcentaje de actividad muscular eléctrica, fuerza muscular, tipo de masticación según el lado de preferencia de masticación, eficiencia masticatoria y tipología facial.

The objective of the present study was to present a systematic review of the literature related to studies that address chewing evaluation methods and their main characteristics. As a research strategy, it was carried out in the PubMed, Web Of Science, Medline, SciELO and Lilacs databases from 2006 to 2020. All available studies were chosen as selection criteria, without language restriction; of the last 14 years; whose participants did not present neurological or psychiatric alterations. They were analyzed based on their relationship with the object of the present study. The keywords used in the search for the articles were identified in the Health Sciences Descriptors (DEDS) being the following: "Evaluation", "Mastication", "Masticatory Muscles", "Masseter Muscle" and "Temporal Muscle". Also using OR and AND as logical operators. 1311 studies were found in the investigated databases, after the review 1278 were eliminated and 33 articles were chosen; and considering only 21 articles according to selection and objective criteria. All the articles reviewed obtained a high degree of evidence (level I) after making a critical evaluation of the scientific evidence, determining that all the articles evaluated were classified as randomized clinical studies with experimental designs. Longitudinal studies with individuals with pathologies being excluded. It is concluded that the method most used is the speech therapy clinical evaluation, by observation and palpation of the orofacial muscles, followed by surface electromyography, electrognatography and the visual analog scale for satiety. The observed characteristics were, number of chewing cycles, chewing speed, percentage of electrical muscle activity, muscle strength, chewing type according to chewing preference side, chewing efficiency and facial typology.

Efficacy of Oil Pulling in the Management of Oral Submucous Fibrosis: A Preliminary Study

ABSTRACT Objective: To evaluate the effectiveness of oil pulling in the management of oral submucous fibrosis (OSMF). Material and Methods: A total of 62 patients clinically and histopathologically diagnosed as OSMF were incorporated in the present study. The subjects are randomly divided equally into two groups, Group A (oil pulling group) and Group B (placebo group). Subjects in Group A were asked to perform OP with sesame oil on an empty stomach in the morning for 3 months and Group B was given placebo capsules for 3 months. Assessment of various clinical parameters was done regularly, and data were analyzed using the Chi-square test. Results: Eighty-two percent had a habit of betel nut chewing, while 18% of the patients had tobacco chewing habits, which were among the main causative factors for OSMF. Clinical improvements in mouth opening, tongue protrusion, difficulty in speech and deglutition, and burning sensation were significant in the Group A. None of the patients reported any discomfort or side effects. The symptoms were not severe in nature and resolved in few days without stopping the therapy. Conclusion: Oil pulling can bring about significant clinical improvements in the symptoms like a mouth opening and tongue protrusion.

Difference in Orthodontic Patients' Perceptions of Essix and Hawley Retainers

Abstract Objective: To determine differences in how orthodontic patients perceive the aesthetics relating to the use of Essix and Hawley retainers. Material and Methods: Photographs of a female patient using an Essix retainer and a Hawley retainer, respectively, were assessed by 70 orthodontic patients aged between 21 and 55 years. All participants were provided with the same images of the two retainer types being worn and were asked to grade the aesthetics of each retainer using a visual analog scale. The significance of differences in orthodontic patient perceptions of aesthetics in the use of Essix and Hawley Retainers in the young adult and adult age groups were tested using the Mann-Whitney test with assumed significance p<0.01. Results: There were differences in participants' perceptions between the two retainers that were statistically significant, with responses varying between young adults aged 21 to 35 years and adults aged 36 to 55 years. According to the VAS, the two retainers' average scores in the total population are 82 for Essix Retainer and 60 for Hawley Retainer in both groups. Conclusion: The Essix retainer as a retention appliance is considered more aesthetically pleasing than the Hawley retainer among both young and middle-aged adults.
